CATALOGUE OF ORTHOPTEROUS INSECTS i\ THE COLLECTION OF THE BRITISH MUSEUM. PART I. PHASMID^J. BY JOHN OBADIAH WESTWOOD, F.L.S., M.E.S., &c. LONDON: PRINTED BY ORDER OF THE TRUSTEES. 1859. QLfof PRINTED BY TAYLOR AND FRANCIS RED LION COURT, FLEET 8TREET. INTRODUCTION. The object in preparing the present Catalogue has been to give at one view a description of all the species of Phasmid^e now in the British Museum Collection, and also a description of those species which are known to exist in other Collections, but which are at present desiderata in the Museum Collection, to enable travellers, collectors, and others to assist in completing the National Collection. The figures have been drawn and lithographed by the author, who has paid great attention, in preparing them, to the proportion which the joints of the limbs and the body bear to each other, which he believes to be one of the best characters for the distinction of species, and one which it is very difficult to express in a moderate space in a description. Mr. W. W. Saunders, and several other entomologists named in the text, have most kindly lent the specimens in their Collections to be compared with those in the British Museum, and with the figures which the author had made from specimens in Foreign Collections, to enable him to determine the species with greater precision. The species in the British Museum are marked with B.M. in the margin. JOHN EDWARD GRAY. British Museum, June 1, 1859. CATALOGUE OF ORTHOPTEROUS INSECTS. Class INSECTA. Order ORTHOPTERA. Orthoptera, Olivier. Hemiptera, pars, Linnmus. Hemiptera, Retzius. Dermaptera, Be Geer. TJlonata, pars, Fabricius. Deratoptera, pars, Clairville. Section AMBULATOMA. This Section, comprising insects with legs formed for slow motion, consists of the single Family PHASMITJUE, Kirby, Serville, G. R. Gray. Phasmodea, Bttrmeister. Phasmina, MacLeay. Spectra, Latreille. Phasma, Stoll, Lichtenstein, De Haan. Prothorax small, not dilated into a shield covering the head. Legs formed for walking ; the fore pair not rapto- rial ; the hind pair not saltatorial ; tarsi 5-jointed. Abdo- men not forcipated at the tip. The Orthopterous insects distinguished by the preceding characters are popularly known under the names of Spectres, Walking-stick and Walking-leaf insects ; the two former names being given to them in allusion to the slender twig- like form of many of the species, and the latter to the leaf- like appearance of others, especially those of the genus Phyllium, which indeed in the living state so nearly re- semble the foliage of the plants on which they reside, as to be distinguished from them with difficulty ; a curious instance of which will be found noticed under Phyllium Scythe. The 5-jointed tarsi, longitudinally folded wings, when present, and abdomen not furnished with an apical pair of forceps, distinguish these insects from the cursorial Forfi- culidee or Ear-wigs ; the small size of the prothorax, or segment immediately following the head, will at once sepa- rate these insects from the cursorial family Blattidce or Cockroaches ; the simple fore legs from the raptorial Man- tidce ; and the hind legs, not formed for leaping, from the saltatorial Gryllidce, Achetidee and Locustida. The species are comparatively of large and often gigantic size ; they frequent the warmest portions of the globe, and the recent researches of assiduous collectors in different parts of the world, have satisfactorily proved that India and the islands of the Indian Archipelago constitute the metropolis of the group. Notwithstanding their large size (may we not, indeed, from analogy with the higher tribes of animals, rather say that, as a necessary dependence upon their large size ?), the insects of this family are harmless herbivorous creatures. The attention of modern entomologists to the great in- crease in the number of species of these insects preserved in our collections, was first aroused by the appearance of the elegant work on the Australian Phasmidse, published by CATALOGUE OF ORTHOPTEROUS INSECTS. Mr. G. R. Gray, and subsequently by the excellent Synopsis which he published of the entire group. The species are, however, far more numerous than has hitherto been supposed, as may be easily conceived from the fact, that notwithstanding the recent labours of G. R. Gray, Burmeister, De Haan and Serville respectively in England, Germany, Holland and France, I have been enabled in the present work nearly to double the number of known species. The chief specific characters exist in the relative pro- portions of the different parts of the body, and the form and position of the spines, lobes and tubercles with which their bodies and limbs are armed. In these respects there is a general amount of resemblance between the males and females, which allows us in certain instances to assume the specific identity between specimens of opposite sexes, the males being smaller, more slender, and furnished with longer legs and antennae ; whilst the females are larger, more robust, and have shorter limbs. In many cases also the females are entirely destitute of wings, or have them only partially developed, whilst they are of full size in the males. Many species, however, appear to be entirely desti- tute of wings in both sexes ; and it will at once be perceived, that this circumstance constitutes one of the chief difficulties in the investigation of the specific rank of the individuals. The amount of development of the sexual appendages at the extremity of the body will, however, enable us in most instances to determine whether an insect be immature or arrived at its full growth. It is, however, very probable that some of the more obscure species described in the following pages may prove to be the immature states of other, perhaps still unknown species, or that they are the sexes of other insects regarded as distinct. As, more- over, we are imperfectly acquainted with so many of the species in consequence of possessing but unique specimens (of the opposite sexes of which we are therefore entirely ignorant), it will be perceived that equally great obstacles exist against our proposing a satisfactory generic distribu- tion of the family. The materials, in fact, which we possess are not sufficient to allow us to tabulate either the groups or the species ; and I think it right to mention these circum- stances as a reason for the omission of these very necessary additions to most modern monographs, which would other- wise be comparatively easy of formation. An instance of such difficulties will prove the impossibility, in our present limited knowledge of the family, of satisfactorily establish- ing the position of species known, as it were, only by halves. Of the large new species from the Feejee Islands, a consi- derable number of the apterous female specimens were first received. With no clue to the condition of the male, the only step was to place the insect amongst those which were known only as wingless species. The male, however, has since been received by the British Museum, and proves that the species belongs to the group which has winged males and apterous females. A tabulation of the species therefore, founded on the supposed apterous condition of the one in question, would have been an erroneous one. Like the Tipulida and other long-legged insects, these species are liable to lose their legs, especially in an early stage of their existence ; but as successive moultings of the skin take place without any material alteration in the general form, the limbs are re-developed ; they are, how- ever, generally distinguished by being of a smaller size than the corresponding limbs on the opposite side of the body. This has been the case with the typical specimen of Bacteria mexicana (Heteronetnia mexicana, G. R. Gray), which has one of its hind legs thus abbreviated, the corresponding leg on the opposite side having been broken off. Hence Mr. G. R. Gray was led to believe that the insect was nor- mally furnished with small hind legs, and was thence led to form it into a separate genus on that account. Several instances will be observed, on looking over the Plates of this work, in which a similar disproportion occurs in the size of the feet. Charpentier also describes an instance of this difference in the size of the legs in a specimen of Bacillus Rossii, as a most extraordinary fact. As the species of this family are often well distinguished from each other by the relative length of the different por- tions of the legs, a description of which could not without great detail be introduced into the specific descriptions, it may be allowed me to state, that in the accompanying engravings I have carefully measured the various parts of each leg, as well as the other parts of the body. I have also given detailed figures, under each species, of the struc- ture of the terminal segments of the body, containing the organs of generation, which, as has been long ago re- marked by the most profound entomologists, afford the most important specific characters. The six basal seg- ments of the abdomen are in general simple, whilst the three terminal ones are modified for the reception of the organs in question. In the male, these three joints, on the ventral side of the body, are shorter than the rest, and swollen ; whilst in the female, the seventh ventral segment is formed into a large, often boat-shaped, ovipositor or operculum, containing within it the other organs of gene- ration modified from the two terminal segments of the body, forming in a few instances long exserted styles or plates. In both sexes, also, the underside of the ninth dorsal segment is furnished with two generally filiform and very short setose styles, but which in the Australian CATALOGUE OF ORTHOPTEROUS INSECTS. species are greatly developed, forming two long flattened appendages. As the development of these three terminal segments is therefore more various in the species than that of the six hasal ones, I have thought it would be advan- tageous to give a separate measurement of the two portions of the abdomen. In the notice therefore of the length of the insect, that of the six basal segments is first given, and then that of the three terminal ones, with the total length, thus : abdom. lin. 6+lin. 3=lin. 9. The presence or absence of ocelli has been used as a sectional character in the family, but, as it appears to me, too great an importance has been allowed to it ; instances will, in fact, be mentioned in the course of this work, in which not only closely allied species differ in the possession of ocelli, but also the opposite sexes of the same species ; and in one instance even specimens of the same sex equally disagree in this respect. Another character has also recently been employed as of generic importance — namely, the simple or furcate condition of the second or main vein in the costal area of the wings. I have, however, met with specimens in which the veins in this portion of the wings were so arranged that it was not possible to affirm whether the vein in question were furcate or not ; whilst other instances have occurred in which the vein was simple in one sex and furcate in the other. The admeasurements are made on the English scale of 12 lines to the inch ; in cases where the measures are de- rived from other writers, they are given in the scales which they have employed. Another character hitherto unemployed in the determi- nation of the species of this family, has afforded me occa- sionally good distinctive peculiarities — namely, the relative size of the two divisions of which the upper surface of the metathorax is composed. This, of course, is modified by the size of the wings ; but still it is too useful to be neg- lected. Most of the recent writers upon this family have followed the primary divisions founded upon the presence or absence of wings, first suggested by Lichtenstein. Latreille, how- ever, followed by Serville, adopted the presence or absence of membranous dilatations on the legs as a primary character ; the former author using the alary character in a secondary sense ; the latter, however, entirely ignores it as a means of tabulation, using the comparative lengths of the pro- and mesothorax as a means for separating the great mass of the species into two primary groups. Considering, as I do, the wings of Insects as their most essentially characteristic organs, as compared with all other Annulose animals, I shall not hesitate to follow the arrangements of Gray, Bur- meister and De Haan in this respect.

Charpentier says the fore legs are quite simple, and only the four hind ones spined. In a specimen in the British Museum from Marseilles, having the thorax granulated and the antenna: 13-jointed, the fore femora are quite simple, the four hind ones have four b 2 CATALOGUE OF ORTHOPTEROUS INSECTS. minute spines close to the tip, and the meso- and meta- thorax have an elevated longitudinal line. 2.

The typical specimen of this insect in the British Mu- seum collection is a male, very slender and cylindrical, with the following proportions : — Head, lin. 1^ ; proth. lin. 1 ; mesoth. lin. 6 ; metath. lin. 5 ; abdom. lin. 12. The antenna; are very slender, filiform, 18- or 19-jointcd, as long as the mesothorax. The head is marked on each side with a dark stripe. The thorax and abdomen are marked on each side with a slender dark longitudinal line, with a lateral paler one. The fore and middle legs are very long and quite unarmed (the hind ones are wanting). The basal joint of the tarsi is remarkably elongated, as are also the ungues and pulvilli. The three terminal segments of the body are very convex (when seen ' laterally), of nearly equal size, the last furnished with a narrow terminal lobe, and with two long, exserted, clavate, curved, anal styles. The three terminal ventral segments are but little CATALOGUE OF ORTHOPTEROUS INSECTS. swollen and not angulated, the last extending to about half the length of the ninth dorsal segment. Dr. Burmeister considers this insect may be the male of his Bacteria gracilis {B. Abdul, Westw.), with broken antennae ; such, however, is not the case, those organs being perfect in the British Museum specimen. His de- scription of the male of his B. gracilis is as follows : — " Glaber, laevis ; femoribus omnibus muticis, posticis 4 cy- lindricis ; antennis 1 6-articulatis in mare ; linea thoracis laterali alba." 8.

Abdomen with a black central dorsal line, except on the terminal convex portion ; the terminal abdominal seg- ments pale huffish-brown. The antennas are short, not reaching to half the length of the fore femora ; they are 15-jointed and slender. The meso- and metathorax are slightly dilated behind for the insertion of the fore and hind legs. The abdomen has the three terminal segments gradually clavate, the last being the largest, convex and rounded behind, with the two anal styles capitate at the tip and exposed, crossing each other behind. The three ventral segments scarcely reach beyond the base of the ninth dorsal segment. The legs are very long, slender and simple. I have adopted the MS. name applied to this species by Mr. G. R. Gray in the British Museum collection. It is here first described. Plate VIII. Fig. 5. The male, of the natural size. 5 a. The terminal segments of the abdomen seen sideways. 10. Bacillus Capensis.

The male is very slender and filiform, with the thoracic segments slightly dilated at the insertion of the legs, and the abdominal segments very slightly and gradually thick- ened from the middle to the extremity of each ; the three terminal joints gradually clavate ; the last very convex, rounded, and margined behind. The head is elongate and subconvex, simple, with a pale line on each side enclosing the eyes, and a dark line behind the eyes and extending along the sides of the thorax and abdomen. The antennae are about four times the length of the head, 18- or 19- jointed ; the joints irregular in length, the basal joint but slightly dilated. The metathorax is nearly equal to the mesothorax in length, its hinder division being extremely short. The abdominal segments are gradually, but very slightly, thickened from the middle to the extremity of each, and the three terminal segments are gradually clavate, the last being very convex, with the hind margin rounded, slightly margined behind ; the three terminal segments be- neath are moderately swollen, short, not extending beyond the eighth dorsal segment. The anal styles are rather long, clavate, setose, and much incurved, one folding over the other. The legs are very long and slender. The female is much more robust than the male, nearly parallel, with the pale lateral line scarcely distinct. The antennae are about half as long again as the head, 18-jointed; the joints irregular in length, the basal joint but slightly dilated. The hind margin of the head has a small depres- sion in the middle ; the thoracic segments are smooth, with a very fine line down the middle of the back, extending in a more distinct carina towards the extremity of the abdo- men. The metathorax is about five-sixths of the length of the mesothorax, and its hinder division is very short. The operculum extends nearly to the extremity of the body ; and the two anal styles are very short, elongate ovate, and setose. The legs are shorter and much more robust than those of the male, and quite simple. Plate XXIII. Fig. 7- The male, of the natural size. 7 a.

The body is terminated by two small porrected styles, the three terminal segments being marked with longitudinal furrows. The operculum extends beneath the seventh, eighth, and greater part of the ninth dorsal segments. The legs are long and simple; the anterior femora are cm-ved at the base, and the middle femora slightly thickened. The body beneath is entirely simple. Plate II. Fig. 7.

This small slender species is of. an obscure brown colour, the male being considerably darker, with a dorsal line along CATALOGUE OF ORTHOPTEROUS INSECTS. the metanotum, and the base of the femora dark red. The male is very slender and cylindrical ; it is not glossy, and is slightly granulose. The head is elongated and narrowed behind the eyes, between which, in both sexes, are two small conical points. The antennae are rather longer than the head, and 20-jointed. The prothorax is armed at each extremity with two small spines. The mesothorax is long and slender, with several pairs of minute conical tubercles, and a large one, bifid at the apex, at the hinder extremity. The metathorax is rather shorter than the mesothorax ; the hinder division very short, and armed, as well as the hinder extremity of the anterior division, with a raised point, as is also the case with each of the segments of the abdomen in the middle of its hinder margin. In both sexes each of the abdominal segments has the base and extremity slightly dilated on each side, arising from the presence of small lateral tubercles. The legs are long and slender ; the femora slightly granulose. The female is more robust, with somewhat shorter legs ; the surface of the body is more granulose ; the elevated point at the ex- tremity of the mesothorax is simple ; and the operculum extends to the extremity of the abdomen. In the specimen of this sex before me, the left middle femur is armed with granules, and an erect spine near the base ; but the middle leg on the right side is simple, probably having been re- produced.

A small specimen, apparently of this species, in the collection of the East India House, brought from Java by Dr. Ilorsfield (" No. 5 "), has the two horns of the head shorter, more foliaceous, with rounded serrated upper edges, and the following proportions : — Long. corp. unc. 4£ ; cap. lin. 2 ; anten. lin. 3 ; proth. lin. 2 ; mesoth. lin. 11 ; metath. lin. 8 ; abdom. lin. 22+ lin.

Another still smaller specimen, in the same collection, also from Java (Ilorsfield, " No. 4 "), agrees with the last- mentioned specimen, but the head is oblong-cylindrical and entirely destitute of horns. Its measurement is as follows : — Long. corp. unc. 3, lin.'7 ; cap. lin. If ; anten. lin. 5£ ; proth. lin. 1| ; mesoth. lin. 9 ; metath. lin. 7\\ abdom. lin. 19 + lin. 5=unc. 2. This specimen seems to unite the present with the fol- lowing species, from which last it, however, differs in the four posterior femora being furnished only with a small lobe-like spine on the under side near the tip. The National Collection possesses several specimens, which might at first sight be mistaken for separate species. One of these, from Silhet, has the head large, oval, and flattened, of a dull luteous-brown colour, with two dark lines on each side behind the eyes ; there is also only one spine on the upper edge of the middle femora near the base ; and the meso- and metathorax are wider (probably arising from pressure in drying). Other specimens differ in the number of spines on the legs. «. 22. Bacillus Hyphereon, Westw. Plate VI. fig. 1.

Plate VI. Fig. 1 . The female, of the natural size. 1 a. The terminal segments of the abdomen seen sideways. I am not satisfied as to the specific distinction between this and Ph. Cuniculus, depending as it does on the exist- ence of horns on the head, and want of spines at the base of the middle legs in the latter, and vice versd in the former. The Entomological Society of London has received an Indian specimen of this species from Mrs. Hamilton, which appears still further to connect the present species with the preceding ; having two diverging spines between the eyes ; the mesothorax granulated ; the middle femur on the right side with three foliaceous spines towards the base on the upper side, whilst there is only one on the left femur; the middle tibia on the right side is also three-spined on the upper edge, whilst the left one is only 1-spined ; the hind femur has also one spine on the upper edge near the base.

Head longer than wide, gradually narrowed from the eyes to the base, which is slightly ele- vated and divided into four parts or small tubercles. The antennse are scarcely one and a half time longer than the head ; the basal joint is oval and flattened ; the remainder, twenty-three or twenty-four in number, are short and fili- form. The mesothorax is slightly dilated above the base of the middle feet. The mctathorax is long, its hinder division rather short. The six basal segments of the abdomen are cylindrical and simple ; the three terminal segments are broken off in the unique specimen before me, so that I am unable to determine the sex. The fore legs are also want- ing ; the middle legs are comparatively short ; the femora have two small lobes on the under side near the base on the opposite angles of the limb, and near the tip they have a minute spine on the under edge ; the tibiae are slender, with a few very minute and slender spines ; the basal joint of the tarsi is about as long as the second and third joints together. The hind legs are rather longer and simple, ex- cept that the femora are armed with a minute spine on the under side near the tip. This species seems to approach nearly to B.

The antennae of the unique specimen of this species in my collection being broken off beyond the basal joint, I am unable to determine precisely whether it belongs to this "■enus or not ; but its apparent affinity to Bac. Hyphereon and Alauna and the dilated basal joint of the antennae favour such an opinion. The head is rather longer than wide, gradually narrowed from the eyes to the base ; the disk is convex (not acutely elevated at the base), covered with numerous minute granules, which are arranged in about seven irregular longitudinal rows. The basal joint of the antennae is moderately large, nearly oval, depressed, with a small carina along the middle. The mcsothorax is long and subcylindrical, but little dilated above the base of the middle legs. The metathorax is long, of equal width with the mesothorax, its hinder division rather short. The abdomen is long, more slender than the thorax ; the segments simple, except the sixth, which is armed beneath at its extremity with a strong deflexed spine ; the three terminal segments of the abdomen are compressed, the eighth segment being about half the length of the seventh segment ; the ninth segment is subtruncate at its extremity, with the outer apical angles rather produced. The oper- culum is long and compressed, black and granular at its extremity, which does not quite reach the extremity of the abdomen ; the two apical styles are small and deflexed. The fore legs are wanting ; the middle ones are rather short ; the femora furnished with a small conical leaflet on the under side ; the under side near the apex is armed with several very minute spines ; the tibiae are armed with several minute and widely affixed spines ; the basal joint of the tarsi is rather longer than the second and third joints taken together. 25.

It is entirely of an obscure grey colour varied with brown, the upper surface slightly rugose aud irregular, with a few- scattered polished granules and short raised lines. The head is oblong, raised between the eyes, where it is armed with two short erect spines ; the hind margin is elevated and slightly tubercled at its sides. The antennae are about half as long again as the head, 11-jointed, the basal joint large and wide at its base, the upper surface with a raised line down the middle. The prothorax above is irregular, with an impressed line in the centre, and with two pro- minent granules in the middle of its fore margin. The meso- and metathorax and the abdominal segments have a raised line down the middle of the back ; the five basal seg- ments have the sides parallel, the sixth is gradually nar- rowed to its hinder extremity, the seventh is parallel at the sides ; the eighth and ninth are long and gradually acumi- nated to the tip, which is entire and pointed, the two minute caudal styles not being visible from above. The opercu- lum is small, and does not extend to the middle of the ninth dorsal segment ; it is Notched at its tip. The legs are rather short and entirely destitute of spines. Plate XXII. Fig. 4.

The male is glabrous and coloured in the same way as the female, but with the markings more suffused (possibly the effect of grease). The head is short and broad, punc- tured on the disc with two minute impressions between the eyes ; the upper lip is prominent and rounded ; the antennae are short and 20-jointed. The prothorax is wider than the head, with the anterior angles rounded, exposing the spi- racles ; the disc is rather uneven and slightly punctured. The mesothorax is considerably dilated, its dorsal portion elevated, and furnished at its hind part with a pair of flat, semiovate, elytriform, dark greenish -brown wing-cases, strongly reticulated, but immoveable, and only extending over the basal part of the metathorax, which latter is spotted like the segments of the abdomen, and bears a pair of minute rudimental wings, of a dirty straw colour, and soldered to the surface at its base. The abdomen is elon- gate, gradually narrowed from the base to the seventh seg- ment in the male, the three terminal segments forming an oval mass ; the three terminal ventral segments short and gaping widely, exposing the complicated male organs of generation. The abdomen of the female is broader and swollen, the lateral margins being more membranous than the disc ; it is gradually narrowed from the base to the extremity, which is rounded and entire. The operculum is short and flat, not extending beyond the middle of the eighth dorsal segment. The legs are dirty olive-brown, mottled with buff; they are short and very strong, and entirely destitute of spines ; the fore femora are not bent at the base. The body beneath is pale luteous-buff, very slightly spotted with dark brown. Plate V. Fig. 1. The male, of the natural size. 1 a. The three terminal segments of the abdomen seen from beneath. 1 b.

The National Museum in Paris contains several speci- mens of this species, which I have examined, and which differ considerably from each other. The specimen repre- sented in M. Gay's work is a large female, which bears a strong general resemblance to, and has rudimentary teg- mina as fully developed and the abdomen as gradually attenuated as in, the female of An. pardalina. Others, of a much narrower form, with the sides of the body nearly parallel, have the hind margin of the mesothorax dilated at each side, with a deep rounded notch in the middle. These are evidently males, the largest measuring as follows : — Head, 2 lines ; prothorax, 2\ lines ; mesothorax (to extre- mity of lateral scales), 3£ lines ; metathorax, 3 lines ; ab- domen, 1 1 lines : total, 23 lines. Another specimen, which is evidently a female, measures more than half an inch longer than the specimen figured in M. Gay's work, its dimensions being :■ — Head, 2 lines ; prothorax, 3} lines ; mesothorax, 4 J lines ; metathorax, 4i lines ; abdomen, 18 lines = 33 lines, or 2f inches. It has the thoracic portion of the body considerably narrower than the female figured by M. Gay ; the prothorax is nearly square and smooth ; the mesonotum rather oblong and only slightly emarginate behind, without any decided indication of the rudimentary wing-scales ; the metanotum rather oval, and the abdominal segments gradually atte- nuated to the tip. From these characters there seems to me to be reasonable doubt whether this specimen, from its larger size, can be a female of this species with the wing-covers undeveloped. I should be rather inclined to consider it as a distinct species, for which I would propose the provisional specific name of An. yrylloides. 8. (48.) Anisomorpha flavomaculata.

The only specimen I have seen of this species is a very imperfect female in the National Collection. It is jet-black, impunctate, very glossy, and has the head and hind legs pitchy ; it is smooth, and destitute of spines or tubercles. The head and prothorax are of nearly equal size ; the former has the sides behind the eyes nearly straight, and the crown of the head is marked with two impressions between the eyes. The prothorax is slightly margined at the sides, the anterior angles spiraculiferous. The mesothorax is gradually widened from the anterior margin to the middle, from whence to the base the sides are nearly parallel ; it is impressed on each side within the lateral margin and slightly in the middle of the disc ; the hind margin is straight, and destitute of rudimentary wing-scales. The metathorax is as broad as the widest part of the meso- thorax, subconvex ; the lateral margin constricted rather before the middle, exposing the dilated flanks of the meta- sternum. The abdomen is gradually narrowed from the base to the extremity ; the three terminal segments are arched above, the ninth being obtusely rounded and ex- posing the extremity of the operculum, which extends beneath the three terminal joints ; the two anal styles are very short and ovate. The four fore legs are wanting ; the two hind ones are short, strong and simple. Plate XXV. Fig. 7- The female, of the natural size. 7 «• The three terminal segments seen sideways. 10. (50.)

The entire body is glossy black and smooth, the fore femora alone being dirty buff at the base ; the body be- neath is smooth and polished, with the joints simple. The head is oval, convex, polished and smooth, with two small impressions in front of the crown. The antennae are short, 16-jointed, the basal joint small, the second square, the remainder oblong and setose. The prothorax is widest behind the middle. The mesothorax is constricted at its base, rather dilated before the middle, narrowed again behind the middle, and dilated at its hind part ; the swollen anterior part bears a large oval raised tubercle. The meta- thorax is more than half the length of the mesothorax, dilated behind the middle, where, as well as near the base, it is furnished with a raised transverse ridge. The abdo- men is long and rather slender, the fourth segment being the narrowest, whence it is gradually dilated to the eighth joint, which is swollen at its sides ; the ninth joint being considerably narrower, shorter, and deeply notched, the two divisions of the notch being dcflexed ; the ninth ven- tral segment is also swollen beneath, and notched at its extremity, which does not extend to the extremity of the dorsal surface ; the basal segments arc transversely swollen across the hind part, and the hind ones are marked with longitudinal impressions. The legs are very long and slender, the fore femora but slightly curved at the base, and all the femora finely serrated from the middle to the extremity on the under side. Plate I. Fig. 6. The male, of the natural size. 6 a. The head, thorax, and first abdominal segment seen laterally. 6 b. The four terminal segments of the abdomen seen laterally. I am induced to place this insect in the present genus on account of its uniform black colour and polished sur- face. It ill accords, however, with the preceding species, owing to the great length of its legs and the nodose struc- ture of its thoracic segments. Genus 4. DIAPHEROMERA. Diapheromera, G. R.

BACTERIA. 21 The above description is copied from Fabricius, and it will be seen that it affords no absolute characters either for the determination of the species or sex of the insect which served for the Fabrician description, and which was con- tained in the Collection of Lund. The insect which was regarded as this species by Mr. G. R. Gray, in the Collec- tion of Mr. Children, is now in the British Museum Col- lection. It is a female, measuring 3 inches 7 lines in length, and was received from the Rev. L. Guilding of St. Vincents. The description given by Mr. G. R. Gray is — " Virescens, corpore subplano, subscabro, linea media ele- vata ; femoribus lineis clevatis striatis." The proportions of the body are — Head, lin. 2£ ; proth. lin. 2; mesoth. lin. 101 ; metath. lin. 4f ; abdom. lin. 17+ lin. 5=lin. 22. The abdomen is destitute of dorsal appendages, and is gradually narrowed to the extremity, where it is slightly truncated, exposing the two small anal styles. The oper- culum varies in length in different specimens ; the full- grown individuals having it extended beyond the last seg- ment of the body about the length of this joint ; in others it only reaches to the extremity of the body. The insect, however, which Dr. Burmeister regards as B. Calamus, is quite distinct from that above described by Gray. His character is — B. Calamus, abdominis segmento 4to supra pone mar- ginem posticum lobato. Mas : laevis, tarsorum articulo lmo subcristato ; relatio mesothoracis ad metathoracem=3 : 2 ; abdominis segmento penultimo utrinque processu acuto dependente. Fcemina : subscabra, thorace spinoso, tarsorum articulo 1 mo cristato ; relatio mesothoracis ad metathora- cem=8 : 5. Long. corp. maris 4" 9'" ; foem. 7" 1'". The male is referred to StolPs fig. 81 (not 87 as mis- printed in Burmeister) ; but Stoll's insect is nearly 5^ inches long, and his figure neither represents any lobe on the fourth dorsal segment of the abdomen, nor any dilata- tion of the basal joint of the tarsi ; whilst the female de- scribed by Burmeister is twice the length of Guilding's specimen described by Gray. An examination of the Lundian specimen, if still in existence at Kiel, can alone solve this question. Stoll's figure 81, on the other hand, is given by Mr. G. R. Gray as the larva of a species of Cladoxerus (" C.fili- formis 1 " G. R. Gray) ; and in the Paris Museum I found a similar male sent from ' De la Mana' by Leschenault, named Cladoxerus gracilis, fern.* I entirely agree with Dr. Burmeister in regarding Stoll's figure as the male of * M. Scrville also (Ann. Sc. Nat. xxii. p. 60) regards this figure of Stoll as the larva of a male of the genus Cladoxerus. a large species of Bacteria ; but it appears to me uncertain to which species it really belongs. 2.

The three terminal segments of the abdomen are very short, the last nearly square, with the anal styles very short, but exserted at the hinder angles of the joint ; the operculum extends beyond the last joint to about the length of the latter ; the four hind femora are simple, except near the tips beneath, where they are armed with a small conical spinose lobe or compound spine. 4.

The female of this species is tolerably well represented by Stoll, whose figure exhibits the unarmed head, smooth body, and angulated basal joint of all the tarsi. Fabricius does not refer his Ph. ferula to Stoll, nor does his descrip- tion — " M. magna, elongata ; corpore filiformi, aptero, viridi ; pedibus longitudine corporis ; femoribus angulatis, posticis 4 apice spinosis ; antennae mediocres, apice fuscae ; corpus totum laeve, glabrum, viride absque elytris et alis " — quite satisfactorily agree with Stoll's figure. Lichtenstein quotes both Stoll and Fabricius under his ferula, with the character — " Ph. pedibus aliquanto corpore brevioribus, tar- sorum articulo lmo triangulari ereeto ; anticorum pedum femora et tibia apice subspinosce." Dr. Burmeister chiefly distinguishes the female of B. Arumatia (ferula, F. Burm.) from those of B. Calamus, muricata and simplex by the smooth surface of the body. Mr. W. W. Saunders possesses an insect of large size, which I refer to this species with some doubt. It is a female, represented of the natural size, in PI. XXIII. fig. 4, and measures 8£ in. in length ; its proportions being — antennae, unc. 4 ; head, lin. 4 ; proth. lin. 3 ; mesoth. lin. 24 ; metath. lin. 15 ; abdom. lin. 48^+lin. 8 + oper- cul. lin. 2-±-=lin. 59. The head is oval, very convex, with a minute tubercle on each side near the inner hinder angle of the eyes. The body is smooth ; the thorax with a very slender raised line on each side within the lateral margin ; the fourth and fifth dorsal segments of the abdomen have a small foliaceous lobe in the middle of the hind margin ; the terminal segment of the abdomen is nearly square ; the hind margin entire ; the two anal styles visible at the sides. The operculum is granulated, and extends a quarter of an inch beyond the extremity of the abdomen (fig. 4 a) ; it is furnished within with two elongated slender filaments bent upwards at the extremity, and extending also a little beyond the abdomen. The legs are long and slender, destitute of spines or lobes, and the basal joint of all the tarsi is angulated in the middle of the upper edge. It is a native of Columbia. If it should ultimately prove distinct, it may receive the name of B. Remphan. 6. (58.) Bacteria filiformis.

This is another insect of which the insufficiency of the early descriptions renders identification nearly impossible. Fabricius, who first described the species, saw it in Dr. Hunter's Museum at Glasgow, and gives " In America me- ridionali " as its habitat. He, however, refers to Herbst's Archives, t. 51. f. 2. That figure, however, represents a species of Bacillus, as above referred to under No. 17. An examination of the Hunterian specimen, if still in exist- ence, will alone clear up the question as to the true Fabri- cian species. Lichtenstein, taking up the species, gives South America and the opposite islands as its locality. His figure represents a very slender male insect, rather more thau 4 inches long, with the body neither spined nor tubercled ; the two terminal segments of the body much swollen, with two short anal styles at the extremity ; the legs long and slender, annulated with black. "The Ph. filiforme in the Ohrtmannian Collection," he observes, "is without doubt a male, full-grown, and yet without any wings. Time will show whether or not the Ph. filiforme be the male of Ph. Ramulus " — evidently meaning Ph. fe- rula (arumatia), of which he states, " Habitat cum preece- dente" (Ph. filiformis). Dr. Burmeister accordingly regards Ph. filiformis as the male of B. ferula (arumatia) ; he however describes it as having the first joint of the tarsi as " distinctius cristato," whereas Lichtenstein expressly alludes to its similarity to the following joints. Burmeister adds — " abdominis seg- mento penultimo utrinque processu acuto dependente nullo." 7. (59.) Bacteria nraricata. Mas.

A male insect in the National Collection, sent from Tapa- jos, Brazil, by Mr. Bates, agrees tolerably well with Lich- tenstein's figure of B. filiformis. It measures rather more than 4 inches in its total length ; the antennce, lin. 27 ; the prothorax, lin. \\; the mesothorax, lin. 13; the metathorax, lin. 9 ; and the abdomen, lin. 19 + lin. 4=lin. 23. Its colour is rufous brown varied with green, the latter colour most prominent on the thoracic segments ; it is very slender and cylindric ; the body and legs entirely destitute of spines or tubercles ; the seventh and eighth dorsal segments of the abdomen are dilated, each of the hinder lateral angles of the eighth being elongated into a deflcxed spine ; the ninth segment is small, widened behind and subemarginate, ex- posing the anal styles at the sides ; the three terminal ven- tral segments are short, with a strong deflexed spine in the middle. The legs are very long, slender and simple, the four hind ones of a dark colour with pale bands. The basal joint of the tarsi is not cristated. This character seems to agree with the male of B. muricata of Illiger, which is from Para in Brazil. A larger male specimen (5i inches long), sent from Villa Nova by Mr. Bates, agrees with the preceding. 8. (60.) Bacteria simplex.

An- tenna; long and slender (reaching to the extremity of the fore tibia;) ; mesothorax long and slender, with a few tuber- cles in front ; metathorax with a small prominent tubercle on each side at about one-third of the distance from the base. Abdomen moderately long, the seventh and eighth segments short, widened behind ; the terminal segment still broader, especially behind ; the outer apical angles rounded ; the posterior margin slightly emarginate ; the under surface furnished along the extremity with numerous small teeth ; the anal styles rather long and thickened, but not visible from above. The three terminal ventral segments short, scarcely extending beyond the base of the ninth dorsal segment, the ninth swollen at its base beneath into a curved horny tubercle ; beyond this, extending beneath the ninth dorsal segment, is a strong, detached, curved, horny point. The legs are moderately long, especially the anterior pair ; the middle and hind femora are rather thickened ; the whole are destitute of spines. Plate VII. Fig. /.

I suppose, however, that it is a male insect. The head is rather small and unarmed ; the mesothorax very long, and (as well as the metathorax) dilated at the insertion of the legs ; these segments are also unarmed. The abdominal segments are simple and slender ; the six basal segments bear a small tubercle on each side close to the base ; they are not furnished with any dorsal appendage. The four hind legs are moderately long ; the femora rather incrassated, and armed near the tips beneath with a strong and acute spine, succeeded by a smaller one ; the tibiae and tarsi are slender and simple. 14.

The male is very slender and cylindrical, the thoracic segments being slightly dilated at the insertion of the legs. The body is quite smooth, scarcely polished, and destitute of spines. The general colour is pale luteous with a darker line down the middle of the back, and a slender pale green line down each side of the body. The head is elongated posteriorly, the hind margin slightly elevated, the middle of the raised edge being depressed ; on each side behind the eye is a dusky line. The mesothorax is very long, the metathorax about half the length of the pro- and meso- thorax. The abdomen is slender ; the segments very slightly dilated at the base, the three terminal segments short, the last truncate and slightly margined behind ; the anal styles deflexed, subcorneal, and curved inwards at the tip. The legs are long and slender, the femora slightly toothed be- neath near the tip. The female is larger, more robust, and of a dirty luteous brown colour, with shorter legs ; the surface of the body is smooth ; the head and thoracic segments finely mottled with minute luteous dots ; on the crown of the head behind is a large, reversed, triangular pale spot, more or less distinct, enclosing a spear-shaped dark one. The thoracic segments are quite simple ; the mesothorax is greatly elongated ; the hinder division of the metathorax occupies only two-sevenths of its entire length. The abdomen is subdepressed, gra- dually attenuated from the third segment to the extremity, where it is terminated by a small, elongate, semi-ovate, constricted lobe, along which runs a fine central carina ; the anal styles are elongated and straightly porrected back- wards, being as long as the preceding segment, which is twice the length of the penultimate one ; the operculum is slender and acute at the tip, which scarcely extends beyond the middle of the last segment. The legs are rather short, and all the femora slightly toothed near the tip on the under side ; the femora and tibiae are more or less distinctly varied with paler spots. In the want of an opportunity of examining the original insect from Antigua, described and figured by Drury under the name of Mantis linearis (Exot. Ent. i. pi. 50), and which was evidently a male insect, closely allied to the male above described, it is impossible to determine whether the latter be really distinct from Drury's insect.

The insect is very long, slender, and cylindrical. It is a male, and is entirely destitute of spines or tubercles. Its proportions are as follow : — Head, lin. li ; proth. lin. 1§ ; mesoth. lin. 1 1£ ; metath. lin. 7\; abdom.lin. 15|-f-lin. 5}=lin. 20J. The meso- and metathorax are slightly dilated at their hind part ; the abdominal segments are rather narrowed in the middle ; the eighth segment is considerably longer than the ninth, which is rather square above, cmarginate behind, with two elongated clavate anal styles porrected obliquely beyond the extremity of the body ; the three terminal ventral segments are dilated, and do not extend beyond the middle of the eighth dorsal segment. The legs are very slender and quite simple. Dr. Burmeister suggests that this insect may be the female of his Bacteria tridens. Desirable as it is to deter- mine the sexes of these insects, and justifiable to suggest the sexual identity of insects described as distinct where sufficient evidence exists of such a relation, it is clearly un- advisable to attempt this where uo grounds exist to enable the student to arrive at such a conclusion. In the present instance we have a male insect regarded as the female of another species, whereas the description "corpus filiforme" should have suggested to Dr. Burmeister that the insect was a male. 16.

The meso- and metathorax are cylindrical, and only slightly dilated at the insertion of the legs ; the abdomen is of nearly uniform width with the thoracic segments, and the six basal segments are of nearly equal length ; the seventh is shorter and more dilated, the eighth very short, the ninth rather longer and more attenuated, and slightly carinated with a minute semicircular terminal appendage, exposing at its extremity two minute conical points, and at its sides the short obtuse anal styles. The operculum is very long (about equal in length to the three basal segments of the abdomen), and extends far beyond the extremity of the body ; it is swollen beneath the eighth and ninth dorsal segments. The legs are moderately long and slender, the anterior femora serrated along the upper edge, the basal joint of the tarsi longer than the remaining joints united ; the middle femora are armed near the base on the upper edge with two spines ; the hind legs are simple.

This species is allied to B. striata, Burmeister. It is green, opake and smooth, except the abdomen, which has one central and five slender elevated lines on each side. The head is small and oblong, without spines or tubercles. The antenme are gradually attenuated, and extend back- wards to the middle of the metathorax. The thoracic seg- ments are gradually dilated from the head to the base of the abdomen, whilst the latter is gradually attenuated to its extremity. The metathorax is rather more than half the length of the mesothorax. The operculum of the abdomen extends slightly beyond the extremity of the body ; it is deeply bifid at the tip, and but little swollen in the middle ; the anal styles are short, exserted at the tip of the body, and incurved. The legs are short and simple, the fore femora moderately widened along the upper angle, and all the femora are quite simple. The basal joint of the tarsi is about as long as the three following joints in all the feet. Plate XXIV. Fig. 6. The female, of the natural size. 6 a.

The head is short and square, with a number of minute raised granules chiefly arranged in lines. The antennae are longer than the head and whole of the thorax, and finely setose ; the basal joint is short and rather broad, the alternate joints brown at the tips. The remainder of the body is also rugose and slightly gra- nulose, the granules of the mesonotum larger and black. The metathorax is rather more than two-thirds of the length of the mesothorax. The abdomen is considerably longer than the front part of the body ; it has the fifth segment considerably dilated on each side beyond the middle ; the seventh segment is nearly equal in length to the preceding, the eighth and ninth are short, and, as well as the seventh, carinated above. The operculum is narrow, not swollen, and scarcely extends beyond the seventh segment ; behind it are two flattened, narrowed pieces, and the two anal styles are very small and terminal. The legs are short and simple ; the fore femora broad, and flattened along the upper edge. The basal joint of the tarsi is about equal in length to the three following joints. Plate XXIV. Fig. 4.

It is quite cylindrical, the thoracic segments being considerably dilated at the insertion of the legs, and the abdominal segments gradually but slightly narrowed in the centre, the extreme base and apex being also slightly con- stricted. The general colour is greenish brown, with the legs slightly mottled with buff. The head is short, broad, and armed with two erect spines behind the eyes on the crown. The antennae are very long and slender, slightly ringed with buff. The prothorax is armed with a pair of erect spines in the middle of its hind part. The mesothorax is very long and slender, with several minute whitish tubercles arranged irregularly ; it is armed at its extremity with two erect spines in the middle, and two smaller ones at the sides. The metathorax is about four-fifths of the length of the me- sothorax and rather more dilated at its hinder extremity, which is armed with two erect spines at the extremity of its anterior portion, and two smaller and wider apart at the extremity of the hinder portion ; it is also armed with a small tubercle and a spine on each side in front of the legs. The abdomen is slender, with the joints slightly widened near the base and extremity, each however being very slightly constricted ; the first segment has a pair of spines on its upper surface at the hinder part ; there is also a cor- responding but much smaller pair on the second joint ; the seventh and eighth segments are wider than the preceding, and the ninth is greatly swollen both laterally and on the upper side, concave beneath ; the terminal ventral segments are much compressed and deflexed, extending to the ex- tremity of the eighth dorsal segment, which is emarginate at its lateral margins ; and the anal styles are large, incurved and obtuse.

This species rivals Phasma nematodes, De H., in its long and slender proportions ; but its fore legs are much shorter, and its antennae longer. The head is wider than the prothorax, with a dark, broad, longitudinal line along the middle of the crown. The antennas are very slender, and reach to the middle of the anterior tibiae. The tho- racic and abdominal segments are very slender and cylin- drical ; the meso- and metathorax slightly dilated at the posterior extremity ; the seventh segment of the abdomen is not more than half the length of the sixth, and is gra- dually widened nearly to its extremity ; the eighth is also widened in the same manner, and the ninth is slightly con- stricted at the base ; it is wider than the eighth, its sides margined, its hind angles rounded off, exposing the anal styles, and its hind margin entire and rounded. The ter- minal ventral segments are mutilated in the unique male specimen in the National Collection. The legs are long and very slender, entirely destitute of spines ; the femora slightly clouded ; the tibiae blackish at the base, aud ob- soletely banded with darker brown. Plate V. Fig. 3.

Saunders. This species is at once distinguished by the great length of the mesothorax, which with the prothorax measures one- third of the entire length of the body. The head is mo- derately elongated, with the sides parallel. The antennae are very long and slender. The prothorax is marked with a blackish line down the middle and at the side, the latter extending along the sides of the meso- and metathorax and abdomen ; the thoracic segments are but very slightly granulose ; the mesothorax is marked with a black spot in the middle of the hind part ; the metathorax does not equal one-third of the length of the mesothorax, its hinder division occupying about two-fifths of its entire length. The abdomen is slender, filiform, the eighth segment longer than either the seventh or last, which is rounded behind, subconvex, with the anal styles beneath deflexed, nearly- straight, and subclavate. The legs are long, slender and simple, with the base of the tarsus more than half its whole length ; the thoracic and abdominal segments are mar- gined on the under side with a black lateral line. The female is much more robust and considerably more granulose, especially on the meso- and metathorax. The head has the sides parallel, and its hind part has a trans- verse row of small tubercles. The antennae are very long and slender. The metathorax agrees in its small size with 32 CATALOGUE OF OltTHOPTEROUS INSECTS. that of the male. The abdominal segments are very slightly marked with a slender longitudinal carina ; they are nearly parallel throughout their whole length ; the terminal dorsal segment is truncate at its extremity, where it is serrated ; and the operculum is deeply and acutely bifid at its extre- mity, and extends beyond the extremity of the body. The legs are long and slender, and entirely simple. The basal joint of the tarsi is about half the length of the tarsus itself. Plate XXV. Fig. 1. The male, of the natural size. 1 a.

The body is long, slender and cylindric ; the extremity of the metathorax slightly dilated at the origin of the hind legs ; the surface of the meso- and metathorax is finely granulose (more strongly so in the male). The head is destitute of any spine or tubercle. The fore legs are slender and simple, the middle legs rather short ; the femora with two small spines near the tip beneath ; the middle tibiae rather dilated near the base on the under side (the hind legs are wanting) ; the basal joint of the tarsi is rather longer than the remaining joints together. The abdomen is slender, cylindric ; the ninth dorsal seg- ment is deeply slit (to about half its length) ; the lateral margins strongly deflexed ; on the under side it is furnished with two short obtuse lobes ; the three terminal segments extend to the extremity of the eighth dorsal segment. The body of the female is terminated by a minute anal lobe, the anal styles are very short and obtuse, and the oper- culum, which is flat, only extends to the base of the ninth dorsal segment. 40.

This species, of which I have only seen a single female, is well distinguished by its very slender form, its long, pos- teriorly attenuated abdomen, terminated by a slender ap- pendage like a tenth joint, and its uniform dull, pale grey colour. The head is greatly elongated and narrowed be- hind the eyes ; in front, between the eyes and the base of the antennae, are three minute spear-shaped impressions. The antennae are slender, extending to the middle of the metathorax. The mesothorax is very long and of equal breadth throughout, and with a slender raised median dorsal line (which extends to the extremity of the abdomen) . The metathorax measures three-fifths of the mesothorax in length ; its hinder division is very short, not being more than one-sixth of its whole length. The abdomen PHASMID^E. BACTERIA. 83 is considerably longer than the anterior portion of the body ; it is gradually widened to the fourth segment, and is afterwards gradually attenuated to the tip ; the three ter- minal segments together are not longer than the sixth, the seventh being equal to the eighth and ninth united ; the last is furnished with a long narrow appendage resem- bling a tenth joint, with its extremity obtusely pointed. The operculum is not at all convex, and extends only to the base of the ninth segment ; the two anal styles are very short and thin, attached on the under side of the ninth joint. The legs are long, very slender, and simple ; the tarsi short, with the basal joint as long as the remainder united. I suppose, notwithstanding its length, that the unique specimen which I have seen is an immature female. Plate XXIV. Fig. 11. The female, of the natural size. 11 a.

The dimensions given above are taken from the typical specimen of B. coenosa in the Hopean Collection, the figure above referred to being too large and robust. The meso- thorax has on each side two longitudinal rows of small granules. The abdomen is gradually attenuated ; the ter- minal segment with the two minute but rather broad anal styles exposed at its extremity. The operculum extends to the middle of the ninth dorsal segment, having a curved and acute horny detached lobe within. The legs are long and entirely destitute of spines. The insect has the appearance of being in an immature condition, the surface of the body having shrunk in various parts. A careful examination of the typical specimen of B. fra- gilis has satisfied me that it is only a young larva of the preceding species. It is represented in the figure above referred to much too large and robust, and with the oper- culum much too developed. It lies in fact quite flat, ex- tending not more than the length of one-third of the eighth dorsal segment ; the remainder of the ventral surface of this segment is occupied with two flat oval lateral lobes and a narrow ventral pointed one ; and the ninth ventral seg- ment bears two curved and rather broad appendages, and two short exserted lateral anal styles. The mesothorax has the rudiments of the lateral rows of granules. The head is dirty white, but having shrunk in the middle, it appears to be marked on each side with a white line. Mr. Hope has applied the MS. name of B. tenuis to a small insect in his collection, represented in PI. XXVII. fig. 2, which I have no hesitation in regarding as the male of B. coenosa. It is very slender, cylindrical, smooth, dirty brown ; the head above marked with a longitudinal pale line on each side behind the antennae ; the abdominal seg- ments are rather narrowed in the middle, the base and ex- tremity of each being gradually widened. The mesothorax is long, and marked on each side with two rows of small black granules placed wide apart ; the eighth dorsal seg- ment is half as long again as the ninth, which is notched at its extremity, carinated above, and furnished in the middle beneath with two long, deflexed, curved, obtuse, setose anal styles ; the eighth and ninth ventral segments are swollen, especially the angulated base of the ninth, which does not extend to more than two-thirds of the length of the eighth dorsal segment. The legs are long, very slender, and simple. Plate XXVII. Fig. 2. The male, of the natural size. 2 a. The terminal segments of the body seen sideways. 42. (94.) Bacteria Samouellii.

The four following insects differ so materially from all the other apterous species, that I am uncertain (in the absence of males of each) whether they should be referred to the other groups of Apterophasmina, or be raised to the rank of separate genera.

The upper surface of the body is entirely obscure whitish- buff varied with brown ; it is flat, opake, and very rugose ; and beneath it is brown covered with minute whitish points. The head is furnished on each side with a large auriform, rugose-foliaceous appendage directed backwards over the fore part of the prothorax, the hind part of the latter being wider than the head. The mesothorax is dilated, being nearly twice the width of the head ; the anterior angles rounded, the sides rather contracted behind the middle, and the hind part widened in front of the insertion of the middle legs ; it bears on its upper surface near its anterior part, two triangular, slightly elevated spaces, the angles of which are directed towards the anterior angles of the mesothorax. The metathorax is shorter than the mesothorax and nearly square, with the outer edges nearly straight. The abdomen is wide, but somewhat narrower at the base than the metathorax ; each segment, from the second to the sixth, furnished at the sides with lateral dila- tations, which gradually increase in size to those of the sixth joint, which are the largest, the upper surface of each marked with curved impressed lines ; the three terminal segments small and narrowed ; the ninth trifid at its extre- mity, exposing the extremity of the operculum. On the under side the meso- and metastemum are quite flat, and the dilated abdominal segments are marked with a raised longitudinal carina on each side ; the whole surface being covered with minute white points. The legs are rather short and dilated ; the fore femora externally serrated, the hind ones with two or three strong serrations near the tip ; all the tibiae flattened and slightly serrated. Plate I.

The whole insect is of a pale brown colour, with the legs paler luteous brown, and the extremity of the abdomen paler ; it is covered with minute pale glossy granules, and has a very fine polished line running along the middle of the thorax and abdomen on the under side ; these granules are fewer on the abdomen. The head is furnished with two small raised spaces between the eyes. The mesothorax is considerably elongated, as is also the metathorax, which is strongly divided near its extremity into two parts by a transverse line. The abdomen is entire, gradually widened to the fourth segment, behind which it is gradually nar- rowed, the three terminal segments being narrower than the head ; the last (ninth) dorsal segment is subemarginate behind, exposing a small rudimental joint, and with two small styles at its outer angles. The operculum extends nearly to the extremity of the ninth dorsal segment, be-- tween which and it are to be seen three pairs of dilated ap- pendages, forming the internal organs of generation. The fore legs (as well as the antenna;) are broken off in the unique specimen in the National Collection. The four hind femora are slightly thickened at the tip, with two or three minute spines, and the tibiae and tarsi are simple. The presternum and mesosternum are divided into two parts by a transverse line across the centre of each. Plate III. Pig. 4. The female, of the natural size. 4 a.

The two horns on the head are very small, and placed between*the anterior part of the eyes. The body is entirely covered with minute white granules, which are less distinct on the abdomen. The mesothorax is strongly dilated at its extremity ; the upper surface of the thoracic and abdominal segments arc destitute of a fine raised longitudinal dorsal line, except the terminal segments of the abdomen, which are carinated ; the seventh dorsal segment is conical, the eighth and ninth obconic, the ninth with a fine slit extending to the base, but with the edges of only the hinder half of the slit apart. The two anal styles are short, deflexed, straight, and affixed in the middle of the under side of the ninth segment. The three terminal ventral segments are gradually dilated from the base to the middle of the ninth segment, which is slightly swollen, its extremity scarcely extending beyond the base of the ninth dorsal segment. The anterior legs have one or two small spines beneath near the tip, and the basal joint of the fore tarsi is elevated, being widest towards the tip ; the middle femora are considerably thickened, armed beneath near the tip with a triangular lobe, ex- ternally denticulated; the hind femora are slender, with several minute spines near the tip.

The typical specimen of L. pterodactylus is a female, in the Collection of the British Museum, and is unquestion- ably the female of L. brevipes. The two horns on the head are very minute and scarcely distinct ; the mesothorax is much swollen behind, the metathorax being considerably wider than the middle of the mesothorax ; the fifth abdo- minal segment is dilated, the sixth narrowed, the seventh nearly as long as the sixth, narrowed ; the eighth and ninth are short and nearly equal in length, the last being termi- nated by a distinct semiovate lobe, like a tenth dorsal seg- ment ; the sixth ventral segment is furnished with a de- flexed point in the middle of its hind margin ; the oper- culum is but slightly dilated, and extends to the extremitv of the ninth dorsal segment, which has its sides notched and armed with two small flattened oval anal styles. The fore tibiae have a small spine near the extremity on the under side ; the fore tibiae have a dilatation near the base and apex on the upper edge, and the basal joint of the fore tarsi is dilated into a large rounded plate on its upper edge ; the middle femora are much thickened, with an an- gulated toothed lobe on the under side near the tip, and an angular projection near the tip on the upper side ; the middle tibiae are very short, with a lobe on both edges near the base.

The insect represented in Plate V. fig. 7. agrees in all its general characters with the male figured by De Haan. It is, however, from Singapore, and is in the National Collec- tion. Its head is armed with two small spines between the eyes, which appear to be wanting in De Haan's specimen ; the antennae have a minute tubercle on one of the joints near the base of each ; the anterior femora are not of equal length. The remarkable structure of the extremity of the abdomen is not represented by De Haan. The ninth dor- sal segment is attenuated and deeply cleft, the two divi- sions incurved at the tip, with the inner edge armed with numerous minute spines, and furnished at the middle with two elongate curved styles. The three terminal ventral seg- ments do not extend beyond the base of the ninth dorsal segment. Plate V.

This species is well distinguished by the two large com- pound spines on the prothorax, and by the large triangular strongly spined space on each side of the anterior part of the mesothorax. The general colour is brownish-black in the male, with the spines and central line down the thorax ferruginous. The female is ferruginous brown, with the abdomen darker coloured, the spines and small tubercles being more ferruginous. The male has the body much less rugose, but with the spines more acute ; the female is covered with small granules, and the mesothorax has the triangular lobe on each side more dilated, flattened, and spined than in the male. The head is nearly square, with two strong spines on the crown behind the middle, with several smaller tubercular spines. The anterior lateral angles of the prothorax are spiracular, surmounted by a small spine ; the disc on each side is* armed with a strong, obliquely erect, bifid spine, each followed, in the female, by a row of small tuberculiform spines. The mesothorax has a transverse row of small spines across the base ; the flanks are armed with a row of about six small spines ; the disc in the male is armed on each side near the front with a strong spine, beyond the middle with a pair of erect approxima- ting spines, and another pair above the insertion of the middle leg. Along the middle both of the meso- and meta- thorax runs a slender, slightly elevated, ferruginous line ; the flanks of the metathorax are also spined, and the disc of the anterior portion is armed with a pair of strong, obliquely erect spines. In the female the spines become more com- pound, the anterior pair of the mesothorax being united to- gether, and to the two middle spines, by a raised transverse lozenge-shaped space, with the edges serrated ; the dis- coidal carina is furnished with two rows of small tubercles. The thorax beneath is unarmed. The abdomen is consi- derably narrower than the metathorax ; the segments are nearly square in the male and very finely rugose, but trans- verse in the female and finely granular, with a transverse ridge of tubercles near the hind margin. The terminal seg- ments of the abdomen in the male are but little swollen ; the terminal dorsal segment slightly emarginate in the middle, and the last ventral segment rounded at its extre- mity ; the terminal dorsal segment in the female is cari- nated, with an impressed line running down the middle of the carina ; the operculum large, but not extending beyond the extremity of the abdomen. The legs are moderately long in the male, shorter and stronger in the female ; the femora, especially in the latter, are armed with small spines on the upper edges ; the under edge in the four posterior femora armed with two spines towards the tip ; the tibiae are rugose rather than spined ; the tarsi are short, with the basal joint small.

Allied in general form to the preceding species. Ob- scure brown, opake and rugose both on the upper and under sides, finely setose. The head is rather longer than wide, with small tubercular spines between the eyes and on the hind part. The antennas are very short and 16- or 1 7-jointed. The prothorax is about the size of the head, with two oblique granulated raised lines ; the hinder mar- gin also tubcrculated. The mesothorax is gradually di- lated, with an elevated tuberculated ridge down the middle ; the lateral margins also granulated, and with lateral curved elevated granulated lines. The metathorax is gradually dilated to the front of the place of insertion of the hind legs, where it is strongly angulated and suddenly narrowed, the hinder division separated from the anterior by a curved impressed line. This portion of the body, as well as the abdomen, is marked down the middle by an elevated tu- bercular carina, and the hind margins of the abdominal segments are armed with larger tubercular spines, the outer posterior angles of each segment being prominent ; the ninth dorsal segment is much depressed and subemar- ginate, exposing the anal lobe resembling an extra segment. The operculum is swollen at the base, and scarcely extends to the extremity of the exposed lobe. The legs are short, the anterior femora curved at the base ; all the femora are armed with small tubercular spines. The mesosternum is flat, with a very fine raised central line, and a row of tubercles on each side, outside of which the mesosternum is angu- lated. The ventral segments of the abdomen are slightly tricarinated along the middle. Plate IV. Fig. 3. The female, of the natural size. 3 a.

This is one of the most repulsive-looking species in the entire family, owing to its uniform dirty brown colour and strongly armed appearance. The male is considerably nar- rower than the female, and the spinulose lobes upon the different parts of the body are more elongated, terminating in longer and more acute spines. The head is short, with the face deflexed ; it is rugose, and armed with two strong denticulated lobes on the crown, behind which are two smaller spines. The antennae are long and slender, with long joints. The prothorax is transverse, armed with two spines in front and two smaller behind. The mesothorax is oblong in the male, nearly square in the female ; it has two small spines near together in front, and two large trian- gular denticulated lobes at the sides, with two small spines behind in the middle ; it is also spined along the edges. The metathorax is shorter than broad in the female, with a pair of small triangular denticulated lobes in front (pro- duced in the male into acute spines) ; the middle is cari- nated, and the sides are dilated into triangular spinose lobes. The abdomen is rugose, serrated along the edges, narrower in the male, broad in the female : the first and second segments in the male with a pair of spines, and the fifth and sixth with two small denticulated lobes ; in the female all the six basal segments have a pair of denticu- lated lobes, those on the second and third segments being the smallest, and those on the fifth largest, subovate and denticulated ; the three terminal segments are broadly di- lated, the last joint erect in the male, terminating in two small rounded lateral lobes in the female. The legs of the male are longer and more slender than those of the female. All the femora and tibise are furnished with numerous small obtuse tubercles, arranged in pairs on the femora. The tarsi are short, with the basal joint scarcely larger than the following joint.

The prothorax is armed with two erect spines at its hinder part. The mesothorax is long and slender, considerably dilated at the insertion of the legs (as is also the metatho- rax), armed with about twelve spines arranged in three ir- regular transverse series. The metathorax has about ten similar spines, four arranged transversely near the middle, two at the extremity of each of the divisions, and two lateral oues. The hind part of each of the abdominal segments is dilated and deflexed ; the middle of the hind margin both dorsally and vcntrally armed with two spines.

I have seen only one female individual of this species, which differs from all the others with which I am ac- quainted in the shape and appendages of the abdominal segments, tuberculated legs, &c. It may possibly be the female of A. Tolima, but I have no proof of such a fact. The head is short, very convex, with various minute spines on the crown, two being of larger size than the rest. The antennae are at least as long as the fore legs. The pro- thorax is furnished with numerous small granules and two small erect points in the middle of the hinder margin. The mesothorax and metathorax are also granulose, with a central slender raised line and two short spines on the disc in front of the middle and two on the hind margin ; the metathorax is short, with two small spines in the middle. The abdomen has the basal segments gradually dilated into an oval mass, convex above, rugose ; the basal segment with two small spines in the middle, and two larger towards the sides on the hind margin ; the second segment has the hinder margin in the middle raised into a broad thin plate, with a spine on each side and two converging carinas in the middle ; the third and two following segments are broad, with the middle raised into a much narrower lobe, the disc with converging carinae and the lateral margins dilated behind ; the sixth segment is much narrower than the pre- ceding ; and the three terminal segments are much com- pressed, and as long as the four preceding segments united, with an acute carina along the middle, the sides slightly rugose ; the seventh segment being as long as the eighth and ninth united. The operculum extends to the extre- mity of the abdomen ; it is but slightly swollen in the mid- dle. The legs are of moderate length, armed with nume- rous small conical lobes on the femora and tibise, those of the fore legs being less strongly marked than in the hind legs ; the tarsi have the basal joint rather longer than the three following joints united.

Obscure blackish-brown and opake, the surface irregu- larly granulose. The head is widened in front to the eyes with two erect spines on the crown in the middle and seve- ral smaller ones near the hind margin. The antennae are scarcely longer than the mesothorax, with the basal joint large, oval and flattened. The prothorax has two raised longitudinal lines posteriorly dentated. The mesothorax is gradually widened from the anterior margin to the middle, behind which its sides are straight ; the disc is irregularly granulated, with a central longitudinal raised line. The metathorax is oblong, with a similar raised central line. The abdomen is rather wider than the metathorax ; the basal segments short, the fifth and following gradually nar- rowed and rather longer ; the sides of each joint are emar- ginate, so that each side of this part of the body forms a series of scallops ; each segment, moreover, is furnished down the middle of the back with two curved narrow raised lines, enclosing between them an elongate-oval space, and the sides are further marked with curved raised lines ; the ninth segment is deeply impressed transversely at a short distance from its base, its apex being acuminated ; beneath it bears two small oval styles, the operculum extending beneath the seventh, eighth, and base of the ninth joints. The legs are rather short ; the femora with very small tuber- cles on the fore edge ; the two hind femora dilated at the base behind. The basal joint of all the tarsi is short.

The general colour is rusty-brown, the surface granulato- rugose, the under side of the body being opake, slightly rugose, with the abdominal segments simple. The head is rugose and furnished above with two large and four smaller spinose leaflets, which are elevated and laterally obliquely porrected, the larger ones being rounded on their anterior upper margin, the crown of the head is furnished moreover with two spines ; the basal joints of the antennae are rugose (the terminal joints are broken off in the unique specimen in the National Collection). The prothorax is rugose and spined at its upper side, with two diverging spines near its hind margin. The mesothorax is spined along the sides, which are gradually dilated to the base of the middle legs ; the anterior part bears a triangular rugose space, armed with spines at the sides, and there is a central longitudinal elevated line with two strong spines in the centre. The metathorax is about half the length of the mesothorax, considerably dilated at the sides in front of the base of the hind legs, armed with two strong spines near its base, and the sides also spined. The abdomen is rugose above ; the extremity of the basal segments with a minute compound lobe in the middle of the hind margin, which becomes foliaccous and much larger in the fourth and fifth segments, but gradually diminishes on the hind segments. The abdomen is as wide as the mesothorax, but narrowed at the base of the seventh segment. The oper- culum extends beneath the whole of the seventh, eighth, and ninth segments, not however extending beyond the latter. The femora are irregularly foliaceo-dentate, both along the fore and hind edges, and the tibiae are irregu- larly but widely serrated on the outer edge. The tarsi have the basal joint slightly larger than the second joint. Plate I. Fig. 5. The female, of the natural size. 5 a. The head and part of the thorax seen laterally. 5 b.

The whole insect is opake, and considerably varied in its colour from green to rusty-brown and lighter buff; it is covered with small granules or spines, and is armed with numerous conical leaflets, which are denticulated at the edges. The head is armed with two conical spinose lobes on the crown, behind which are two erect spines. The antennae are long and slender, with the tips of the joints (in the basal half of the antennae) darker-coloured than the basal portion. The prothorax is armed with two erect spines in front, and four in a transverse row behind. The mesothorax, in addition to the pair of large triangular spi- nose leaflets, is armed with four pairs of erect spines. The metathorax also bears a pair of smaller spinose triangular leaflets, and two pairs of dorsal spines, one pair close to the fore margin, and one pair beyond the middle. The six basal segments of the abdomen are armed at the sides with triangular spinose lobes ; and on the upper surface near the base of each is a pair of small spines wide apart, with a pair of large spines approximated together in the middle of the hind margin, accompanied in the third and fourth segments by a spinose erect lobe ; the three terminal segments are very much compressed, the eighth segment being furnished above with an ovate erect serrated lobe ; the ninth segment is produced in a slender plate at its ex- tremity ; the operculum extending to the extremity of the abdomen, but with its extremity deflexed. The legs are PIIASMID/E. CEROYS. 61 long and slender, considerably variegated in their colours ; the anterior femora and tibiae irregularly spinose and ser- rated ; the four hind femora with five or six spines on each of their angles, that near the apex being the largest. The middle right leg in the specimen drawn had apparently been reproduced, being smaller than the opposite limb, and destitute of spines. The size of the spines of the body varies in different individuals. One specimen in Mr. Fry's collection has the abdomen destitute of the lateral lobes, whilst the dorsal lobes of the third, fourth and eighth segments are larger than in the specimen which I have figured.

Uniformly opake, red-brown, with the sides of the body nearly parallel ; the entire surface of the body covered with minute granules and short slight irregular lines. The head is oblong and simple. The antennae nearly half the length of the body and very slender. The mesothorax long and slightly widened at its extremity, as is also the metathorax, which has its hinder division very short and slightly indi- cated. The second segment of the abdomen is furnished with a large erect leaflet at its hinder margin, and the fol- lowing segments are also furnished on their hind margins with a series of small tubercles, from which run fine striolae into the disc of the segment ; the ninth segment is slightly wider than the rest, it has a small spine on each side, and it is notched at its extremity, a small lobe appearing be- tween the divisions. The operculum extends beneath the seventh and eighth and base of the ninth dorsal segments. The legs arc of moderate length ; the anterior simple, with the femora curved at the base ; the intermediate femora are furnished on the upper fore edge with three large rounded leaflets, the hind edge being tuberculated ; the hind femora are irregularly and slightly serrated, as are the four poste- rior tibiae. The basal joint of all the tarsi is nearly equal to the three following in length. Obs.

This species, of which I have seen only a single female individual, is entirely of a dull brown colour, slightly varied with luteous ; it is finely rugose, with slender elevated lines and minute granulations wide apart. The head is elon- gated behind the eyes, with a dark mark down the centre of the crown. The antennae are long and slender, the basal joint oval and depressed. The mesothorax is mode- rately elongated and gradually widened, with a raised cen- tral line extending also along the metathorax, which is gradually wider than the mesothorax, and about three-fifths of its entire length ; its hinder division is short, with a raised, slightly curved line on each side. The abdomen is not longer than the thorax ; it is wide and subdepressed, with the terminal segments gradually attenuated ; on either side of the slightly raised median line is a curved line simi- larly raised, and another nearer the lateral margins scarcely defined. The three terminal segments are strongly cari- nated ; the seventh joint considerably longer than the pre- ceding ; the eighth and ninth of equal length, each being nearly equal to the sixth. The operculum is swollen at its base ; it extends a little beyond the extremity of the abdomen, and is deeply emarginate at its tip.

Opake dull brown ; elongate, cylindrical, the meso- and metathorax being rather dilated in their hind part. The head is tuberculated in its hind part. The antennae are multiarticulate, the basal joint of moderate size. The pro- thorax is armed with three pairs of erect spines and smaller lateral tubercles. The mesothorax is long and slender, except at its hind part, which is dilated ; it is armed with several spines at its anterior and posterior parts, two of larger size being close together and adjoining the hind margin. The metathorax bears two erect spines a little in advance of its middle, and immediately behind these are two minute elytriform scales lying close upon the back, of a pale rosy colour with a black line down the middle of each ; the hind part of the metathorax is dilated, with the sides spined in front of the hind legs. The abdomen is long, slender, and cylindrical, with the seventh joint gra- dually widened at the hind part, and the eighth gradually narrowed to its extremity ; the ninth segment is widened behind, with its outer angles deflexed and bent inwards, the inner edge being armed with strong spines set transversely, and furnished with two hirsute styles ; the terminal ventral segments not extending beyond the eighth dorsal segment. The legs are rather short, with the femora thickened to- wards the tips ; the anterior femora are curved at the base, and the inner edge is armed with three small spines near the tip ; the middle and hind femora are armed with several smaller and two larger spines next the tip. All the tibiae are simple. The body beneath is paler brown, opake, with the segments simple, covered with very minute whitish points, which are more numerous on the anterior part of the mesostemum.

This species is distinguished by its wide flattened form, its granulated surface, and the pale longitudinal stripes on the upper surface of its body. The head is armed with small pointed tubercles, as well as the prothorax, on which those next the median line are larger and arranged in pairs. The antennas are broken off at the twenty-second joint. The mesothorax is considerably dilated at the sides in the middle, the lateral margins being serrated ; in the widest part the disk is raised into two elevated conical tubercles ; beyond the middle it is narrowed, but is again dilated at the place of insertion of the middle legs. The metathorax is ob- long, serrated at the edges, dilated at the base of the hind legs, and furnished on the middle of its upper side with two small elytriform scales. The abdomen is wide, with the sides of each segment dilated, the disk with a longitudinal raised vitta and several longitudinal lateral darker lines and marks ; the three terminal segments are considerably nar- rower than the rest ; the ninth is entire, and furnished at the sides with a pair of small styles ; the operculum ex- tends beyond the ninth dorsal segment, appearing like an extra joint from above. The legs are short and robust; the two fore femora are curved at the base ; the four poste- rior are tuberculated along the fore edge and irregularly serrated beneath ; the tibiae are slightly dilated within near the base, the outer edge slightly and irregularly lobed. The body beneath is opake and entirely covered with very minute whitish granules. Plate III. Fig. 3. The female, of the natural size. 3 a. The head and thoracic segments seen from the side. 3 b.

The male is very slender, cylindrical, smooth, pale lu- teous buff. The antennae are rather longer than the fore femora. The mesothorax is marked with two very fine black lines down each side. The tegmina are small, nar- rowly ovate, pale luteous-coloured, areolated, with small black dots enclosed in the areolae. The wings are minute, steel-blue and glossy ; the costal area greenish at the ex- tremity with black dots, sanguineous at the base. The ab- domen is slender (the three terminal segments are wanting in the unique male in the National Collection) ; the basal segments have a rudiraental lobe almost indistinct in the middle of the hind margin of each. The legs are long and slender, the four hind ones finely serrated on the under side of the femora. The female is more robust and brown, with the meso- thorax and abdominal segments granulose ; the tegmina and wings are coloured as in the male ; the middle of the central abdominal segments is more distinctly lobed ; the terminal segment is slightly notched in the middle, with the two very short thick anal styles visible at the sides. The operculum scarcely extends beyond the base of the ninth dorsal segment. The legs are shorter and more ro- bust ; the four hind femora are more strongly serrated on the under edge. Plate VIII.

This species agrees so entirely in all respects, size in- cluded, with the females of Bacillus Peristhenes, that I was, at first, tempted to believe that the unique speci- men in the British Museum Collection was one which had acquired an extra development in its transformations. The abdomen is attenuated from the base to the apex, where it is furnished with a pair of anal styles as long as the eighth and ninth dorsal segments ; it is of a luteous colour, smooth, impunctate, but not glabrous. The head has a rather deep impression between the eyes. The mesothorax is finely granulated, and furnished at its hinder extremity with a pair of minute oval tegmina. The metathorax is also fur- nished with two minute rudimental wings, extending a very short distance beyond the extremity of the tegmina. The four hind femora arc armed beneath, between the middle and the tip, with two to four minute spines ; the tibiae are slender and simple. The operculum is small, scarcely ex- tending beyond the middle of the eighth dorsal segment. The antennae and two fore legs are wanting in the single female specimen which I have examined.

Long and slender ; the male very slender and filiform, entirely of an obscure red-brown colour, with the surface of the body smooth, except the upper surface of the meso- thorax and base of the metathorax, which are densely covered with very minute granules. The head is of mode- rate size and unarmed. The metanotum of the male is simple ; but that of the female is furnished with two minute, free, moveable, oval, reticulated scales, resembling rudimental tegmina. The abdomen is long and simple ; *he terminal segments in the male are short, forming an oval mass, the last terminated by two small lobes exposing the short caudal styles. The terminal segments of the female exhibit a structure I have rarelv met with in the family : the ninth segment has its apical outer angles rounded, with the short anal styles visible at the sides ; the extremity is slightly emarginate, exposing a minute ter- minal rounded lobe. The operculum is long and deeply- incised at the tip ; it extends far beyond the terminal seg- ment, and is accompanied on either side by a slender com- pressed elongated style, channelled externally, with a deep slit at its apical end, and with the extremity of its upper edge prolonged into a spine, detached and lying outside of the upper edge of the lower division ; within the space thus formed lie two long and flattened slender filaments, nearly as long as the operculum, incurved towards their tips. The legs are long, slender, aud simple ; all the tarsi, however, have a small node at the base of the first joint, which is setose on the under side. Plate IV. Fig. 4.

Phibalosoma (male), Cladoxerus (male), and Cladomorphus (female), G. R. Gray, Serville. Cladoxerus, Burmeister, Serville. .Males with wing-covers and wings. Females apterous. Head destitute of ocelli. Legs long, and generally spined. Males very long, slender, and cylindrical. Mesothorax several times longer than the prothorax. Metathorax shorter thau the mesothorax. Tegmina small, much shorter than the metathorax, oval. Wings small, or of moderate size. Females more robust, with much shorter legs. Ovi- duct generally extending beyond the extremity of the abdomeu. Considering the possession of a pair of wings in the males and the absence of alary organs in the females as the leading character of this group, we find several distinct types of structure among the males as well as amongst the much fewer females with which we are acquainted. The males of Phibalosoma serratipes and Rypharpax, for in- stance, have the terminal dorsal segment of the body 72 CATALOGUE OF ORTHOPTEROUS INSECTS. elongated, pointed, and bifid at the tip ; whereas in the Australian Ph. Caprella, the Manilla Ph. longicorne, and the New World species allied to Ph. gracile, it is of the usual shape, and in the Brazilian Ph. LePeletierii it is greatly elongated : on the other hand, the females of Ph. Pytho- nius have the oviduct twice the length of the three terminal segments of the body, and in Ph.Le Peletierii, fern., it ex- tends a short distance beyond the extremity of the abdo- men ; whilst in PA. Acanthopus, fern., it is not visible at all from above, the terminal dorsal segment being truncated. Corresponding variations may possibly be simultaneous in both sexes of the different types of form, but they do not appear to be concurrent with the geographical distribution of tbe species. The males of some of the smaller species approximate very closely to some of the more slender species of Neeroscia, and it is not improbable that it will be found necessary to remove them to that genus or to Phasma, should their females prove to be winged. In the uncertainty which exists as to the apterous or winged condition of the females of the types of the genus Cladoxerus (CI. serratipes, gracilis, &c), I have preferred retaining the generic name given by Mr. G. R. Gray to the male of the Brazilian species (Ph. Le Peletierii). Hence, if these females should ultimately prove to be winged, it will be necessary to remove them from the genus and restore to them the generic name of Cladoxerus. 1. (186.)

I have adopted the usual plan, where the sexes of a spe- cies have been described under different names, of retaining that of the male in preference to that of the female, although the latter has been employed for both the sexes by Bur- meister and Charpentier. I have the greater pleasure in doing this, as commemorative of the name of my late friend the Count Le Peletier de Saint Fargeau, one of the most ardent and laborious of entomologists. The elongated operculum of the male, with the remark- able arrangement of the chief veins of the costal area, are characters which I have not observed in any other species of the family. 2. (187.)

Macgillivray). B.M., &c. This fine species, which is one of the most striking re- cent acquisitions in the family, was collected by Mr. Mac- gillivray in Ngau, one of the Feejee Islands. The male, of which I have only seen a single specimen, quite recently sent home by Mr. Macgillivray, is very long, slender, and cylindrical. The head is destitute of ocelli. The mesothorax long, and slightly dilated at the insertion of the fore legs. It is luteous, with a greenish tinge ; the two rows of dorsal spines are much stronger than in the females, and black ; there are also two rows of minute spines on each side, and two still smaller along the prosternum. The metathorax has a row of very small points along the flank, with a deep double impression near the hind extremity of the metasternum, beyond which is a point on each side. The abdomen is long and filiform ; the three terminal segments small. The tegmina small and truncate, greenish, with the lateral margin yellow. The wings are large; the costal area pale luteous buff, greenish at the base, with a yellow- line, the hind part with a row of small brown dots ; the principal vein is furcate in the left wing ; the hinder area is very pale buff, rather darker at the tip, the veins pale reddish brown. The legs are long, with the femora rather strongly serrated. The female has the head small, oval, convex, and desti- tute of spines or tubercles, with a small transverse impres- sion between the eyes. The antennae are long and slender, and consist of about twenty-nine or thirty joints, gradually becoming very long after the eighth joint. The prothorax is small, oblong, the surface irregular, the fore margin excised, the anterior angles truncate, a small deep puncture within each angle. The mesothorax is the widest part of the body, being much dilated before and slightly contracted behind the middle ; the upper surface is entirely smooth, except towards its sides, where it is slightly punctured ; the con- necting lateral membrane with a row of small black spines. 71 CATALOGUE OF ORTHOPTEROUS INSECTS. The metathorax is about two-thirds of the length of the mesothorax, oblong convex, smooth, with the lateral margin on each side armed with a similar row of small black spines ; the six basal abdominal segments are large, smooth, convex, and destitute of spines, with an acute lateral margin ; the three terminal segments are small and narrowed, the eighth segment being the shortest, the ninth gradually attenuated and rounded behind, and with the two short caudal styles scarcely visible at its sides. The operculum is very long and boat-shaped, extending the length of the three termi- nal dorsal segments ; beyond the extremity of the abdomen it is furnished within with two compressed, narrow, sabre- shaped appendages, as long as the operculum itself. The legs are moderately long, the thighs strongly, and the under edge of the tibiae less strongly serrated. A female specimen in the National Museum, smaller than the usual-sized individuals, has the sides of the meso- thorax almost parallel. Plate XXXV. Fig. 3. The male, of the natural size. 3 a.

The male is long and very slender, destitute of spines, except on the legs. The head is much broader than the prothorax, oval, very convex in its hinder part, the middle of which is elevated into two minute conical tubercles of unequal size. The mesothorax is long, smooth, and of equal width, except at the hind part ; it is of the same length as the metathorax. The tegmina are obovate, much constricted towards the base, the middle being raised into a large rounded tubercle ; they are dirty ashy brown, with the base of the outer margin luteous. The wings are large, but narrow, very slightly tinged with brown, and with darker brown longitudinal veins. The costal area is pale greenish brown, pale luteous along the base of the outer margin ; the chief vein is furcate in both wings at half an inch from the base ; the transverse veinlets are very numerous, straight, and distinct. The abdomen is long, cylindrical, and smooth ; the seventh segment gradually widened, and the ninth deeply slit at its extremity ; the PHASMIDiE.

The abdomen is long and thick ; the sixth segment is lobed on each side ; the seventh longer than the sixth ; the eighth and ninth short, the latter emarginate — truncate at its ex- tremity ; anal styles short and deflexed. The operculum does not quite extend to the extremity of the body. The legs in both sexes are strongly serrated along their different angles, those of the male being longer and more slender ; the basal joint of all the tarsi is compressed along its upper edge.

A unique male of this species forms part of the National Collection. It is remarkable for the great length of the abdomen, spinose legs, and especially the structure of the terminal segments of the abdomen. It is slender and cylin- drical, the body being destitute of spines. The head rather large, oval, and subdepressed, nearly smooth, with a pale patch in front, and another on each side behind the antennae pale yellow. The antennas have the extremity broken off at about 1| inch from the base ; the joints remaining are long and finely hairy. The mesothorax is slender and cylindrical. The tegmina are small and narrow, with a strong carina elevated considerably in the middle. The wings are moderately large, but not wide ; they are pale brown, with the costal area rather darker brown ; the chief vein is furcate at a short distance from the base. The ab- domen is very long and filiform ; the seventh dorsal seg- ment gradually widened, the eighth gradually narrowed, the ninth elongated and deeply bifid, the two divisions gaping considerably and denticulated on their inner surface, with the two anal styles inserted on the under surface, and not so long as the divisions of this terminal segment ; the three terminal ventral segments are abbreviated, not ex- tending to the extremity of the eighth dorsal segment. The legs, especially the anterior pair, are elongated and rather slender ; all the femora rather strongly serrated on all their edges ; the tibiae less strongly serrated, the four posterior with a more conspicuous spine on the outer edge towards the base ; the basal joint of the tarsi rather flattened and dilated.

Py- thonius, with longer legs, the head larger and flatter, and the mesothorax unarmed. It is also closely allied to Ph. Hypharpax, but has the wings and mesothorax con- siderably longer, and the terminal abdominal segments dif- ferently constructed. The head is oblong, wider than the prothorax, flattened above, the posterior angles rounded, and the hind margin suddenly deflexed ; between the eyes in front is a short transverse curved impression. The eyes are large and prominent. The antennae moderately long, with about twenty-four joints, the middle ones long. The mesothorax long, very slender, and simple. The tegmina are elongate-ovate, constricted before the middle, with the median carina elevated into a strong obtuse conical lobe. The wings are long and narrow ; they are hyaline, slightly- tinged with brunneous, with dark brown longitudinal veins; the costal area darker, especially towards the anterior mar- gin, the margin itself towards the base with a luteous stripe ; the transverse veins are very distinct, and the me- dian one simple. The abdomen is long, slender, and simple ; the seventh joint two-thirds of the length of the sixth, and gradually widened ; the eighth gradually nar- rowed ; the ninth more attenuated, compressed, longitudi- nally cleft ; the apex truncate, the two divisions spinulose within, and the anal styles deflexed ; the three terminal ventral segments are short and gradually thickened, extend- ing only to the middle of the eighth dorsal segment. The legs are long and slender, the whole being serrated ; the four posterior tibiae with a small lobe near the middle of the upper margin ; the basal joint of the tarsi longer than the rest united.

Serville' s figure above referred to represents the insect at least double the natural width, although of the proper length ; the fore legs are also too short. The tegmina are very small, narrowed and depressed between the base and middle, the hinder portion being swollen, and the carina in this part rounded. The ter- minal segments of the abdomen are shorter than in CI. Cryphaleus, and destitute of dark dots. The hind legs are also shorter than in that species. I have examined and drawn the insect in the Berlin Museum, described by Burmeister as the female of this species thus: — "Unicolor; femoribus anticis in marginibus to CATALOGUE OF ORTHOPTEROUS INSECTS. serratis ; tibiis posticis supra nunc lobatis nunc integris ; operculo vaginali longissimo, lanceolato, canaliformi. Long, corp. cum operc. 5" 10'"; anten. 5'"." The insect, in fact, closely resembles my Plate XXV. fig. 9 ; the abdomen is, however, considerably broader, the metathorax as well as the legs rather shorter, and the middle femora have two or three serrations on the under side. I do not understand on what grounds Burmeister considers this as the female of this species, there being, as it appears to me, no analogy in the structure of the body or legs to warrant such a con- jecture. 16.

The great length of the mesothorax and its very slen- der proportions render this a very conspicuous species, of which, however, I am only acquainted with the single male represented in the accompanying figure. It is very long and slender, destitute of spines, smooth, of a greenish- brown colour, with the antenna; and legs red-brown. The head is wide, with two very small conical tubercles between the eyes, and a small circular impression behind the clypeus ; it is fulvous-coloured. Eyes very prominent.

Burmeister, in his Revision of the Order in Germar's ' Zeitschrift ' (ii. p. 41), and De Haan (p. 131), have re- ferred this genus to Cladoxerus, Serv. (Phibalosoma, supr.), evidently, however, without having had an opportunity of seeing the insects in nature ; the former, at least, had failed to recognize the species, as I found the male in the Berlin Museum, described by him under the name of Cyphocrania acanthomera ; thus proving, in effect, its generic distinction from Cladoxerus, and its much closer affinity to Cypho- crania. The fine female insect figured by me in the ' Arcana En- tomological pi. 49, is so closely allied to the female of M. inuncans, that I do not hesitate to refer it to the genus, although it possesses extremely minute rudimental teg- mina ; as is also the case with the insect in the Berlin Mu- seum from the coast of Africa, described below under the name of M. parallela. It is with much greater doubt that I refer the large apterous Brazilian female insect, also figured in my ' Ar- cana,' ii. pi. 61 (D. yibbosa, Burm.), to this genus: not only its geographical range, but also its unarmed legs and peculiar-shaped thorax separate it from the Old World species. 1.

I have been compelled to propose a new genus for a PHASMID.E. IIETEROPTERYX. 81 curious species, of which both sexes have recently been sent to this country by Mr. Wallace from Aru; the female of which bears a close general resemblance to the species of Ceroys, but the antennae are those of Bacillus ; whilst the male is slender and winged, with the legs spined as in the female, but having the lobes of the four hind legs reduced to dilated spines. 1.

Saunders. The male of this curious species is slender and subcylin- drical, of a brownish luteous colour, with the abdomen glossy. The head is rather longer than wide, rugose above, especially behind, with large eyes. The antennae are short, about 20-jointed ; the basal joint broad and flat. The prothorax is rugose, and armed in front with two short spines ; two larger spines also arm the middle of the front margin of the mesonotum, which is covered with minute whitish granules, as is also the mesosternum. The teg- mina are small, oval, and with the middle of the carina mo- derately elevated, the disc of the tegmiua within the carina being marked with a black spot. The wings are of mode- rate size, opake whitish, with a rather darker outer margin ; the costal area pale luteous, with the fore margin browner, and with the chief veins (especially the median one) marked with black lines ; the latter is furcate near the base. All the legs are finely serrated, with the four posterior femora armed along each of the two upper angles with four eqiu- distant spines, the third being the largest and subfoli- aceous. The extremity of the abdomen in the unique male which I have seen is distorted, but the terminal ventral seg- ments are but slightly swollen and very short. The tarsi are short, with the basal joint not so long as the remaining joints. The female is opake brown, more rugose than the male. The head subquadrate, with the hind margin very rugose. The antennae are still shorter than those of the male, with the basal joint more dilated. The pro- and mesothorax are spined as in the male. The metanotum has on each side, near the middle, an oblique row of short diverging spines ; and there is a conical rugose lobe just in front of each of the posterior coxae. The abdomen is cylindrical and ru- gose ; the anterior segments have two small erect spines in the middle of the anterior margiu, and a diverging one at each side of the posterior margin ; the three terminal segments have a raised and flattened irregular carina along the middle, which in the eighth segment is prolonged and furcate, and the last joint is spinose above ; the whole under-surfaee is armed with small spines. The operculum is swollen at its base, and extends to the extremity of the body. The legs are short and rugose ; the spines larger than those of the males. The tarsi are very short, with the basal joint not longer than the two following joints. Plate XXXIV. Fig. 4. The male, of the natural size. Fig. 5. The female, of the natural size. 5 a.

Body spinose, furnished in both sexes with moderate- sized tegmina, and small wings of nearly equal size in both sexes ; costal area not distinct, covered by the tegmina when at rest. Body of the male rather slender, with the metathorax swollen ; of the female broad, with the basal segments of the abdomen dilated ; the terminal segment with a corneous elongated joint-like appendage, extending considerably be- yond the extremity of the operculum. Legs robust and spined, but not lobed. Anterior femora not sinuated at the base. Tarsi with the basal joint short.

Saunders, Hopeiano Oxonise (olim nostr.), et B.M. This species approaches as closely to II. Be Haanii as the latter does to II. Mulleri, De H. It is, however, very much larger (a number of specimens being uniform in size), and is distinguished by the group of four spines at the base of the tegmina, and the mottled appearance of the latter. The general colour is reddish brown, obscure, slightly rugose, and armed with numerous small and a considerable number of larger spines, those upon the body of the male being much stronger than those of the female, while the legs of the latter are shorter, stronger, and more strongly spined. The head is armed on its hind part with eight strong spines, arranged in two rows ; the anterior lateral angles of the prothorax have two strong spines, and there are two near the hinder angles ; on the middle of the disc in front are two erect diverging spines, and a transverse row of spinelets near the hind margin. The upper surface of the mesothorax has a somewhat elevated triangular space, bearing a strong pair of spines in front, a pair in the middle, and an elevated group of four between the places of insertion of the tegmina; a raised line also runs ob- liquely on each side from the fore angles to the base of the tegmina bearing a row of minute spines, and the extreme lateral margin bears about six spines on each side. The PHASMIDiE. HETEROPTERYX. 83 mesothorax of the male is conical ; of the female consider- ably wider at the base than the hind part of the prothorax, and gradually widened backwards. The metathorax has the sides much swollen and rounded, and strongly spiued on the margin, with a very strong spine on each side oppo- site the middle of the tegmina. The abdomen of the male is subcylindrical, gradually narrowed to the fifth segment, the edges spiued as well as the upper surface, a pair of spines in the middle of the disc of each being the largest. The female has the abdomen broad, subdepressed, nar- rowed from the fifth segment, the lateral margins finely spined, the upper surface armed with very minute spines, the three terminal segments spineless, the ninth carinated, and furnished at the tip with an oblong joint-like append- age with four small teeth on each side ; the three terminal ventral segments in the male are much swollen. The operculum of the female extends to the extremity of the anal appendage. The tegmina are oval, the extremity being more pointed, the base with a strong pale carina' extending one-third of their length : the wings extend to the base of the abdomen. The legs of the male are mo- derately long ; those of the female shorter and more robust, strongly spined throughout, the spines of the inner edge of the hind tibiae very strong and curved. The mesoster- num is armed with three small spines on each side, and the metasternum with two ; the basal segments of the abdo- men with four longitudinal rows of spines ; the coxa; of all the legs are also strongly spined. The species is named in honour of G. R. Gray, Esq., whose writings upon the family have so greatly contributed to our knowledge of the species. Plate XXX. Fig. 2. The male, of the natural size. 2 a.

Pitchy black, opake, with a chestnut tinge ; strongly spined on the head, thorax and legs ; the abdomen with smaller spines, the spines tipped with dark fulvous. Head nearly square, with two small spines between the eyes, and eight larger on the hind part in pairs. Antennae 26-jointed, the basal joint of moderate size, the last joint rather longer than the two ' preceding together. Prothorax wider than the head, widest behind, divided into two parts by a trans- verse impression ; the anterior part with four strong spines, the posterior with two. The metathorax is gradually di- lated ; its dorsal portion is raised and narrowed behind to the base of the tegmina, it is rugose, with a transverse row of six strong spines in front, two wide apart in the middle and two close together behind, and two smaller ones close to the origin of the tegmina ; the lateral deflexed part is armed with numerous strong spines. The tegmina are oval, extending rather beyond the hind part of the metathorax, and entirely covering the short wings ; the sides of the metathorax are swollen and strongly spined. The abdo- men is nearly as broad as the metathorax in front, and gra- dually narrowed to the extremity ; the six basal segments are armed with small spines in the middle of the upper surface as well as along their lateral margins ; the ninth segment is carinated down the middle, emarginate behind, terminated by an oblong carinated appendage notched at its sides and apex. The operculum is swollen, and extends beyoud the end of the ninth segment, but not beyond the exposed anal lobe. The legs are of moderate length, the anterior femora not curved at the base ; all the femora an- gulated, and strongly spined along each angle ; the tibiae are strongly serrated, the hind ones with incurved spines on the inner edge. The body beneath is opake ; the mesostemum on each side with a row of three short spines, and two more in the middle behind ; the metasternum has two spines on each side, two in the middle, and two in the middle of the hind margin, which extends backwards between the hind legs ; the three basal abdominal segments are also furnished with two spines on each side near the middle.

I have here restricted the genus to the large species, of which an excellent figure of the female was first published by Drury under the name of Mantis gigas, the natural history of which has since been investigated in the Island of St. Vincent's by the late Rev. Lansdown Guilding, whose specimens of both sexes, with the eggs and larva?, are pre- served in the British and Hopeian Museums ; to this is added the Platycrana venustula of Serville, and a third West Indian species. The other species introduced into the genus by Gray appear to differ in no generic respect from his Aplopus mi- cropterus. It seems to me to be most probable that the Pleesiophyllum Havaniense of MacLeay's MSS. (Phasma H., ante, p. 34, Plate XXII. fig. 7) may be the full-grown female of PI. venustula, or an allied species ; in which case, we shall have females of the group without any rudi- ment of wings or wing-covers. The peculiar manner in which the horns of the head are developed in the female of this insect indicates an intimate relationship with the fe- males of Ilaplopus. 1. (215.) Diapherodes gigas. Mas.

The general colour of the specimens of this insect in the Hopeian Museum is greenish yellow j when alive, it was probably uniform green, the specimens having been pre- served in spirits. The surface of the body is smooth, but not glossy. The head is deflexed in front, the crown fur- nished with two tubercles, the right-hand one being the larger ; the hind part of the head has several small spines. The antennae are of moderate length, the joints beneath arc black, beyond the middle also every fourth or fifth joint is dark at the tip. The prothorax has two small spines at its hind margin ; the mesothorax is gradually widened, with a few minute tubercles or spines on its disc, two near the fore margin being more distinct ; the sides of the meso- thorax and metathorax are white, the former also armed with a row of small spines. The tegmina are small and somewhat triangularly ovate, green, with the costal margin beneath black ; the wings are very small and hyaline ; the costal area broad, coriaceous, green, with a black spot beneath. The abdomen is long, the anterior segments rather broad, the remainder gradually narrowed to the end, the three terminal ones being more suddenly narrowed. The operculum is boat-shaped, as long as or longer than the two or three terminal segments of the abdomen. The legs are short and robust ; the anterior femora with two or three and the four posterior femora armed beneath with six or eight spines ; the tibiae dilated near the base, the tips with several small spines ; the basal joint of the tarsi short.

Gray (Syn. Phasm. p. 34). Haplopus, Sect. A., Burmeister (p. 57C). Haplopus, Sect. C, Be Haan (p. 127). Males with the body elongate and slender, the metatho- racic portion more robust. Females broader, subdepressed, with the abdomen greatly elongated, and the oviduct extending considerably beyond the extremity of the abdomen. Head in both sexes with two unequal-sized tubercles, that on the right side generally the larger. Ocelli want- ing. Antennae of moderate length. Mesothorax con- siderably elongated, often spinose. Tegmina small, oval, shorter in the females. Wings of the male large ; those of the female very small, not longer than the tegmina, not reaching to the extremity of the metathorax, with but few longitudinal veins. Legs comparatively short, thick in the female, and often spined. Anal styles very small in the female, more elongated and deflexed in the males. The species of this group, as here restricted, are natives of the West Indian Islands, the habitat of Amboyna given by Stoll to H. micropterus being clearly erroneous. As a group, they are very closely allied to Biapherodes gigas of Drury ; indeed Gray unites several of them generically with that insect. I cannot, however, separate them from H. micropterus. It would therefore perhaps be more natural entirely to sink the genus Biapherodes, uniting its species with the others. 1. (218.) Haplopus Evadne, Westw. Plate XVIII. fig. 6, male.

It is very long, slen- der and cylindrical ; the general colour luteous brown, but the head, prothorax, and extremity of the abdomen, as well as the antennae and legs, are tinged with green. The head is convex, with two slightly raised tubercles on the crown M CATALOGUE OF ORTHOPTEROUS INSECTS. behind the eyes. The antennae are rather thick, with about fifty-six short joints. The mesothorax is long, with about a dozen small black conical spines disposed in irre- gular rows along two-thirds of the anferior length. The tegmina are elongate ovate, not strongly angulated before the middle ; they are of an elegant yellow colour, with five bright green longitudinal streaks along the chief veins. The wings are opake white, with a delicate pinkish tint, especially towards the anal margin ; the longitudinal veins almost colourless ; the costal area is coloured in the same manner as the tegmina, the chief vein being furcate at the distance of about half an inch from the base. The abdo- men is very long and cylindrical, slightly widened at the base ; the three terminal segments widened, the extremity rather angularly emarginate in the middle ; the three ter- minal ventral segments moderately swollen, not extending beyond the eighth dorsal segment ; the anal styles extend- ing backwards, and forming a small forceps. The legs are short and rather thick, especially the four posterior femora, which are spined beneath ; the basal joint of the tarsi is about as long as the three following joints. Plate XVIII. Fig. 6.

In insula " St. Domingo," Haiti. In Mus. Saun- ders et Hopeiano Oxoniae (olim nostr.). This species is very closely allied to H. Evadne, but is at ouce distinguished by its longer limbs, narrower wings, and peculiar coloration. The head is very convex, and armed on the top of the crown with two acute conical points, black at the tip, the right one being the larger ; the sides of the head are whitish. The antennae are very long, rather thick, composed of about sixty short joints. The prothorax is armed with two small spines near its anterior margin. The mesothorax is slender and cylindrical, armed with six or seven spines placed in two rows irregularly. The tegmina are elongate ovate, brown, glossy, with a strongly raised conical tubercle near the base ; the outer margin and two elongated patches beyond the middle are white. The wings are opake white, slightly tinged throughout with pink, the whole of the veins being dusky coloured ; the costal area is pale brown, with a number of small elongated whitish patches; the base is black. The mesosternum is armed with six small spines arranged in two longitudinal series, and the metasternum with two pairs of similar but rather larger spines ; the sides of the latter are marked with a narrow fulvous stripe. The abdomen is long, slender and cylindrical ; the terminal segments white at the sides, and scarcely dilated ; the three ventral segments short, not ex- tending to the extremity of the eighth dorsal segment, and but little swollen, and the anal styles are rather thick and obtuse at the tips. The coxae of all the legs are fulvous, the legs themselves green, moderately long and slender, with the four posterior femora armed beneath with a few small spines. Plate XVIII. Fig. 5.

Neither Drury nor Fabricius mention the two mesotho- racic spines (indeed Fabricius says that the character of the thorax constitutes the chief difference between this spe- cies and H. bispinosus). Drury' s figure, however, clearly exhibits the two erect black spines in front of the meso- thorax. According to his figure, the head is also desti- tute of the two tubercles, which are likewise unnoticed by Fabricius, who expressly describes them in H. bispinosus. Another character apparently distinguishing H. Jamaicensis from the latter species, are the green stripes of the teg- PHASMID.E. HAPLOPUS. 87 mina, which have the outer margin yellow. The habitat also (although vaguely indicated by Fabricius), as respects H. bispinosus, seems different. With these exceptions, I should have regarded the two insects as identical. 4. (221.)

Stoll incorrectly considered that the insect which he re- presented in his figure 77 was a male in the pupa state, and also that it came from Amboyua. There is no doubt, how- ever, that it is a female arrived at the perfect state, and that it is a native of the West Indies. The insect consi- dered as this species in the Berlin Museum by Burmeister is a female, with the following proportions : — Long. corp. cum operc. unc. 5f ; cap. lin. 3 ; proth. lin. 3; mesoth. lin. 12 ; metath. lin. 8 J ; abdom. lin. 28 +lin. 6-J- + operc. lin. 8£ = unc. 3, lin. 7 ; tegm. lin. 5 ; alae long. lin. 5. It has the legs shorter and thicker than is represented by Stoll. The two tubercles on the head are obtuse, the right one being larger than the left. The prothorax has two pairs of tubercles in front ; the mesothorax is armed with numerous but small spines ; the four hind femora have three or four strong teeth along their hinder edge ; the sixth abdominal segment is a little dilated on each side behind, and the operculum is considerably broader at the extremity of the body than the ninth ventral segment. Burmeister describes the larva as having " auf den 4 Hinter- scheiikeln 2 Hautlappen und einen erhabenen Hinterrand am lsten und 2ten Itiickensegment." 6. (223.) Haplopus spinipes.

Hab. ? Mus. Soc. Linn. Lond. I am unable to satisfy myself whether the insect in the Cabinet of the Linnsean Society, described as above by Mr. G. R. Gray as a male pupa, is not in reality a male imago with rudimental tegmina and wings. The specimen whilst living has evidently undergone some accident, as the left hind leg is scarcely more than half an inch long, whilst the right-hand one is longer than the entire abdomen. The head in this specimen, as also in the female, is armed with PHASMID,E. HAPLOPUS. 89 two spines, the prothorax with several pairs of smaller spines, and the mesothorax with numerous spines placed irregularly ; the sides of the metathorax in the female are also spined, as well as the under side of all the femora in the male and female. The male has the three terminal seg- ments of the body thicker than the preceding ; the female has the sixth abdominal segment rounded, and rather di- lated at the sides ; and the operculum of the same sex ex- tends nearly an inch beyond the extremity of the abdomen. 12.

The male of this species is quite slender and subcylin- dric, with a glossy surface, and in its dried state of a light brightish brown colour, with the sides of the head and of the terminal segments of the abdomen white. The head is oblong, very convex, with two strong short horns in the middle of the crown, that on the right side being the larger ; they are tipped with a short acute black point ; there are also two small black granules on the hind part of the crown of the head. The antennas are long and slender ; the joints are about twice as long as thick, there being sixty-four joints in each antenna. The prothorax is fur- nished near its fore margin with two black points ; and the mesothorax has four pairs of similar points, the hinder part being quite smooth. The tegmina are about two-thirds of the length of the mesothorax, oval, with a strongly elevated protuberance in the middle ; they are of a dirty glaucous- grey, with the edges varied with white markings. The wings are about half the length of the entire body, milk- white, with a slight rosy-brownish tinge ; the anterior part dull glaucous-grey, darker at the base, with white markings, especially on the fore margin. The abdomen is very long and slender ; the sixth segment with a small lobe on each side ; the three terminal segments rather wider than the rest, and short ; the terminal ventral segment not extending beyond the eighth dorsal segment, and considerably dilated at its base ; the two terminal styles porrected and obtuse. Legs short and strong ; the anterior pair simple ; the four posterior femora slightly spined along the under edge ; basal joint of the tarsi about as long as the three following joints. Meso- and metasterna with a few black points. The female is of an opake dirty glaucous-white colour. The horns of the head of unequal size, as in the male. The pro- and mesothorax much more thickly marked with small points, black at the tip. The tegmina are short and nearly rounded, thickly reticulated with paler nervures, and with a moderately raised tubercle beyond the middle. The wings are nearly equal in length to the tegmina ; their an- terior portion is dirty greenish-brown ; the hind part thickly reticulated with black veins. The abdomen is very long and gradually attenuated to the tip ; the oviduct is very long and boat-shaped, the exserted portion being nearly equal to the four preceding segments in length. Plate XI.

Abdomen of the female with the sixth segment strongly dilated on each side ; oviduct ex- tending far beyond the extremity of the body. I am induced to follow M. Serville in separating the curious insect upon which he has founded this genus from the preceding group, although it is certainly very closely allied to such species as Haplopus micropterus (angulatus, Burm.) and H. spinipes, G. R. Gray (Ph. angulata, Pal.B.) ; the dilatation of the legs, the lobed condition of the hind ones, the curious mirror-like patch at the base of the costal area of the wings, and the dilated sides of the sixth abdo- minal segment seem to warrant this step, which will, I have no doubt, be fully confirmed when the male shall be dis- covered. 1.

In Mits. Ilopeiano Oxonise et B.M. PHASMIDjE. PALOPHUS. £»] Deceived by the locality of Australia given to this species by Mr. G. R. Gray, as well as by his short, incomplete, and not quite accurate description, I had regarded the male in the British Museum Collection as a distinct species ; but an examination of the typical specimen in the Hopeian Col- lection at Oxford has convinced me that it is identical with it. Mr. Hope's specimen is also a male, and it has no locality attached to it ; so that the locality of Australia given to it must have been conjectural. Both sexes are contained in the Royal Museum at Berlin, and the female is also in the Leyden Museum. The following is Mr. G. R. Gray's description of this species : — " Brunneus, cornubus inter oculos duobus longis, compressis ; thorace rugoso ; alis brunneis, margine supe- riori nigrescentibus, basi nigra, nervis obscuris ct albo ma- culatis ; tegminibus in medio paulum elevatis ; pedibus longis gracilibus simplicibus hirsutis." The male is very slender, with a disproportionately long abdomen, the hind legs not extending beyond its extremity, and with a comparatively short mesothorax. It is ashy- coloured, with the abdomen brown, and the legs obscurely fasciated. The head and anterior parts of the thorax are granulated ; the former with a large double setose horn, porrected in front, arising between the eyes. The ocelli are large ; the anterior placed in front of the frontal horns, and the lateral ones at their sides. The antennse are up- wards of 2\ inches in length, finely setose ; they consist in the British Museum specimen of thirty-eight joints, but some at the tip are probably broken off ; the joints are elon- gated, the base of each pale, and the apex darker. There is a small spine on each side of the head between the eyes and mandibles. The mesothorax is not longer than the head and prothorax united ; it is slender and subcylindrical. The abdomen is very long ; the three terminal joints short, the last emarginate at the tip, exposing the ends of the short anal styles ; the three terminal ventral segments are ab- breviated, the last not extending beyond the middle of the eighth dorsal segment, it is moderately swollen. The teg- mina are elongate-ovate, with a strongly elevated tubercle between the base and the middle ; the fore margin is whitish, with a black oblong patch. The wings are large ; the costal portion pale brownish-buff, with a dark brown spot at the base ; the hind portion brown, with pale buff spots irregular in size, but mostly circular and arranged on the longitudinal veins. The legs are slender and setose ; the anterior pair considerably elongated ; the fore femora with a small spine on the upper edge in the middle ; the middle and hind femora with a small spine near the base beneath, and a little further removed from the base, above ; all the tibire have two small spines on the outer edge, one before and the other beyond the middle ; the tarsi are short, with the basal joint of the fore legs rather dilated. The female has the wings half the length of the abdo- men. The mesothorax is proportionably longer and much wider than in the male, with two pairs of tubercles on its upper surface. The third, fourth and fifth segments of the abdomen are produced on the hind dorsal margin into two small pointed lobes ; the eighth segment is very short ; the ninth longer, truncate at its extremity ; and the oper- culum does not extend beyond the middle of the ninth dorsal segment.

In Mus. Saunders. Specimens of this species of large size have been col- lected by Mr. Wallace in Malacca, which I at first con- sidered sufficiently distinct to form a separate species. I can, however, after more mature consideration, only regard them as forming a local variety, in which the body is quite smooth, the head broad, and the eyes large. The antennae are long and slender, upwards of 70-jointed, the joints beyond the middle becoming more and more indistinct, except at intervals of four or five joints, which gives the appearance of long compound joints. The head is pale luteous, with seven longitudinal dark streaks on its hinder portion, the middle ones being transversely united between the eyes. The prothorax is square, the anterior angles spiraculiferous, transversely impressed across the middle, and marked with blackish stripes, two of which form a V in the middle of the front half; the mesothorax is also con- siderably varied with blackish, which colour leaves a pale frontal hastate and two reuiform lateral patches of luteous. The metathorax is nearly as long as the pro- and meso- thorax united. The abdomen is long, ITarrow and convex in the male, wider in the female, with a dark longitudinal median stripe, having two larger oval and several smaller dark spots on each side of it. The legs are moderately long and simple, luteous-coloured ; the femora and tibia; with the extremity and a fascia across the middle black ; the tarsi black, except the pale basal joint. The wings are brown; the costal area pale green, with numerous PIIASMID/E. ASCIIIPAS.MA. 93 black spots and dots, lenving the veins green ; median vein simple. The terminal segments of the abdomen of the male are very much swollen both above and below, and the anal styles are deflexed, broad, and emarginate at the ex- tremity. The female has the terminal joint rounded and entire, the operculum very much swollen, and the anal styles short and oval. Plate XV. Fig. 2. The variety of the male, of the natural size. 2 a.

This species is allied to the preceding in being entirely destitute of the rudiments of tegmina ; it has the an- tennae very long and slender, the legs annulated, especially near the extremity of the femora, and the costa of the wings obscurely clouded. It agrees in size with the male of A. affine, De Haan ; but the wings are at least one-third larger, and the last segment of the under side of the body shorter. The general colour is pale brown. The body is narrow and subcylindrical. The head is rather wider than the prothorax, and is marked in the middle of the crown behind with a small dark spot. The prothorax is rather longer than the head, and the mesothorax is about one-third longer than the prothorax. The antennee are long and slender, with the joints short ; beyond the middle they are marked at irregular distances with a dusky ring at the extremity of one of the joints, leaving two, three, or even four joints between the dusky and slightly incrassated joints. The tegmina are entirely obsolete. The wings are very pale brown, and rather opake, with the costal area darker lu- teous-brown, slightly clouded with irregular ill-defined paler patches ; all the veins are pale brown, the principal longi- tudinal vein darker than the rest, and slightly spotted with pale dots towards the base. The legs are slender ; the fore femora nearly straight at the base ; all of them are ob- scurely annulated with dusky, and with a more decided ring near the tip ; the intermediate tibia? are armed be- neath with several minute spines. The abdomen is long and slender, slightly clavate at the tip, the last joint de- flexed and emarginate at its extremity ; the two anal styles rather long, deflexed and incurved ; the seventh ventral segment is distinct, but the two following are coalesced into a somewhat conical segment, scarcely swollen beneath, and extending nearly to the extremity of the ninth dorsal segment.

Hab. In Insulis Philippinensibus et Ceram. B.M. This species seems, at first sight, closely allied to Ph. Forstenii of De Haan ; but the very peculiar shape of the wings and the dilated anal styles of the male, together with the reticulated costal area of the wings of the male (not noticed in this sex by De Haan, although he describes it in the characters of the female of his Forstenii), the much larger size of the insect, and smaller head, prove it to be a distinct species. The general surface of the body is smooth, opake, and black. The head as wide as the metathorax, with the eyes large. The tegmiiia are minute, stipuliform, with the outer angle of the apex slightly produced. The wings are dark brown, with black longitudinal veins ; the costal area is of the same colour, but its anterior margin is luteous, and it is thickly reticulated with veins of the same colour. The abdomen is long and slender, clavate at its extremity ; the anal styles deflexed and incurved, gradually widening to beyond the middle, and with the apex obliquely truncate ; the seventh ventral is distinct ; but the eighth and ninth are coalesced into a convex joint, not suddenly swollen at the base. The legs are short and rather thick ; the anterior femora straight at the base. Plate IX. Fig. 2. The male, of the natural size. 2 a.

This is more robust than several of the closely allied species, and is further distinguished by the shorter rounded wings, unicolorous body, and very numerously dotted costal area of the wings. The head is rather broad and convex. Antennae about 50-jointed, moderately long and slender, especially at the tips, where the joints are almost indistinct. Protborax about two-thirds of the length of the mesotho- rax, its anterior division convex. Mesothorax nearlv cylin- drical, with a fine line on each side within the lateral margin. Tegmina minute, erect, stipuliform, pale luteous. Wings of moderate size, broad, each covering more than half a circle, pale brown, with darker longitudinal veins, the trans- verse ones semitransparent ; costal area pale luteous buff, with the cells (formed by the minute transverse veins) brown ; median vein simple.

It is closely allied to A. Daunus, but has shorter legs and larger wings. The accompanying figure is taken from a specimen from Malacca, which agrees with the original type in the British Museum, except that the wings are slightly longer and broader. The head is small, luteous brown, obscurely marked with brown spots and lines. The antennae are rather short and very slender ; the joints pale at the base, dark at the extremity. The pro thorax is about one-fourth longer than wide, cylindrical, with a slightly impressed median line. The mesothorax is rather wider than the prothorax, and about twice as long as it is broad ; its sur- face is slightly granulose, and varied with paler dots and small dark spots in front and behind. The tegmina are reduced to two small, acute, obliquely elevated black spines. The metathorax is about the length of the mesothorax, its hinder division occupying about two-thirds of its whole length. The abdomen is long and slender ; the basal seg- ments with two black spots in front of each ; the three ter- minal joints short. The operculum swollen at the base ; the apex much compressed, extending to the middle of the ninth dorsal segment. The wings are moderate-sized, pale browu, with the longitudinal veins rather darker, the trans- verse ones scarcely visible ; the costal area is luteous brown, with numerous small, irregular, more or less distinct whitish spots. The legs are short, setose, single ; the fore femora thick, scarcely excavated at the base ; the tibiae slender, and slightly ringed with pale luteous ; hind legs uniformly coloured beneath.

This is one of the largest species of the genus, and is well distinguished by its short mesothorax, spiniform teg- mina, setose legs, and the round spots of the costa of the wings. The head is small ; the eyes prominent, but not so wide as the mesothorax ; it is dirty luteous, with a square black patch in the middle of the hind part, and with two blackish streaks behind the eyes. The antennae are slender, with the joints gradually elongated, and with the tips of the joints dusky ; they are nearly destitute of hairs (the tips are broken off in the only specimen I have seen). The prothorax is longer than the head, dirty luteous, with a dark patch in the middle of the fore margin, and a dark lateral spot behind the eyes. The mesothorax, as well as the metathorax, has a large pale luteous spot in the middle of its anterior dorsal portion. The abdomen is dirty lu- teous, considerably varied with dusky markings ; the three terminal dorsal segments are short, the seventh being con- stricted at the base. The operculum is slightly boat- shaped, and extends nearly to the extremity of the last dorsal segment ; the anal styles are deflexed and obtuse.

The prothorax is about two-thirds of the length of the me- sothorax ; the surface of both is smooth, and varied with dark longitudinal stripes on a paler ground, the central dark line being the broadest, and interrupted in the middle by a small bilobed pale oval spot. The tegmina are small, erect, and spiniform. The wings of the male are of mo- derate size, those of the female reaching to the middle of the fourth dorsal segment of the abdomen ; comparatively narrow, of a very pale brown colour, slightly darker along the outer margin, with rather darker longitudinal veins ; the costal margin brown along the anterior portion, the hinder portion irregularly clouded with whitish and brownish-buff markings ; the median vein simple. The abdomen long and simple, varied with dark longitudinal marks ; the three terminal joints very much swollen in the male, those of the ventral surface large, extending beyond the ninth dorsal segment ; the apex bent upwards, obtuse at the tip, and slightly emarginate, widely gaping, enclosing the dilated male organ terminating in an acute point ; the anal styles thick and deflexed, dilated, oval, pointed, setose.

Having, however, fortunately obtained in Paris the fragments of the three typical specimens described by Serville, I have ascertained its distinctness not only from that species, but also from any of the preceding. In the very pilose legs it approaches P. pilosipes of De Haan ; but that author's description of the identity in the size of the wings of both sexes, and the maculation of the third vein of the costal area, sufficiently distinguish it from De Haan's species. It also approaches A. affine of De Haan, but the shorter wings and swollen terminal segments of the abdomen of that species suffi- ciently separate the two ; the latter character also, as well as the simple anal styles and larger size, distinguishes P. Daunus from Serville's insect, although they agree in the dissimilar size of the wings in the opposite sexes. The Servillean specimens are in a deplorable condition ; but the abdomen of the male is perfect, and shows that the terminal ventral segments are not in the least swollen, and that the anal styles are short, but very broad and deflexed, with the extremity emarginate-truncate. Serville describes the legs generally as very pubescent ; but I can only dis- cover this character in one pair of legs, and suppose them to be the posterior. Genus 23. LOPAPHUS, Westw.

The antennae are as long as the pro- and mesothorax, 22-jointed, the basal joint large. The pro- and mesothorax are finely granu- lated ; the latter wider than the former, with the sides nearly parallel. The abdomen is widened from the base to the fourth and fifth segments, which have a longitudinal raised space in the middle of the hind margin terminating in a small membranous lobe ; the seventh segment is much narrowed, forming with the two following segments an oblong-ovate mass. The operculum is very wide, and ex- tends slightly beyond the extremity of the abdomen. The tegmina are elongate-ovate, with the ordinary carina near the base strongly marked. The wings are rather short, extending to about the hind margin of the third abdominal segment ; the costal area is brown at the base, forming ill- defined dark spots towards the middle of the area, which is pale straw-coloured, the apical portion being rich chest- nut-red ; the hinder area is steel-blue, with numerous white spots, one of larger size than the rest near the middle of its anterior portion. The legs are long ; the fore femora strongly serrated along the upper edge ; the tibia? with numerous minute spines ; the middle femora with a large foliaceous lobe, pointed at the tip, at about one-third of the length from the base of the upper edge, with two small aeute lobes between it and the apex ; the hind femora with several small spines and a larger lobe before the middle ; the four hind tibiae with a small lobe on the outer edge near the base, and several small spines on each of the edges.

The accompanying figures are taken from the two typical specimens (male and female) in the Hopeian Collection. The head is furnished with two pairs of tubercles close to the hind margin. The ocelli are large in both sexes. The antennae of the male are setose, with the joints long,, the basal joint narrow (the extremity is broken off). The pro- notum is flat, and widened behind, with the lateral margins slightly elevated. The mesonotum has a raised, somewhat heart-shaped space, armed with short lateral spines, as well as with several on the disc ; there is also a curved row of short spines on each side, running from the anterior lateral angles to the base of the tegmina, and the extreme lateral margins are also spined. The tegmina in both sexes are oval, with a very slight angulated elevation in the middle. The wings are large ; the costal area pale ashy buff, irregularly varied with brown, the chief vein furcate ; the membranous area pink, gradually shaded off to brown, the longitudinal veins strong and dark brown. The abdominal segments are furnished on each side with thin membranous lobes, acute at the hind angle, very much smaller in the male than in the female ; the former has the terminal dorsal segment of the abdomen elevated in the centre, whence it is furcate to the extremity ; the anal styles are long and obtuse ; the operculum of the female is simple, and extends to the ex- tremity of the abdomen. The legs are rather short in both sexes, with the femora serrated externally in the female. Plate XXXI. Fig. 6. The male, of the natural size (with the extremity of the legs and wings omitted). 6 a.

The simple structure of the abdominal segments of the unique male of this species, preserved in the Hopeian Museum, separates it from the genuine species of Prisopus, with which it agrees in the membranous and serrated ap- pendage of the legs. I do not doubt, when the female comes to be known, that it will be necessary to form a separate genus for its reception, it being here placed pro- visionally in that of Xeroderus. Plate XXXVI.

The female only of the unique species of this Brazilian type of form is known, and is contained in the National Museum of Paris. Burmeister's conjecture that it is the male of Prisopus spinicollis is without foundation, the sim- ple structure of the legs being of itself sufficient to prove the wide separation of the two groups. 1.

I have followed Dc Haan in adding several species to this genus, which, however, seem to differ in various im- portant particulars from the original type (of which I have not been able to find any specimen in the Paris Collections, but which seems very closely allied to Phasma spinosum of Fabricius = Ph. corniceps, G. R. Gray, of which the type is contained in the British Museum). It is indeed possible that the Eastern species of this group will require forming into a distinct genus when a better knowledge is obtained of Serville's type. 1. (266.) Creoxylus corniger.

Sarawak, Borneo (B. Wallace). In Mus. Saun- ders et Oxonise (olim nostr.). This species is very closely allied to Ph. Diacis, De Haan, but differs in the uniform size of the spines of the head, the shorter mesotliorax, and the differently con- structed terminal joints of the abdomen. The head is sub- quadrate, rounded at its hinder part, granulose, the gra- nules arranged in lines ; eyes very prominent ; a row of four, small, equal-sized spines across the hind part of the head, and a small round black spot on each side behind the eyes. The antennae are rather short, dark brown, with numerous small luteous rings. The prothorax is finely granulose, as is also the mesothorax, which is gradually widened behind, and armed with a few very small spines in its anterior half. The tegmina are oval, obscure, blackish brown, with the inner margins paler ; the carina is coni- cally elevated rather before the middle of its length, and is dilated in its hinder portion into a large semicircular lamina. The wings are stained blackish brown, with the costal area darker, the veins varied with black or blackish dots, the median vein simple. The abdomen has the fifth and sixth segments wider than the preceding, and mar- ginated ; the seventh and eighth are subquadrate, the eighth with a lobe in the middle of its hind margin ; the ninth seg- ment small and conical, with the two small anal styles se- tose ; the terminal ventral segments form a large operculum extending beyond the tip of the abdomen, with its truncated extremity subdenticulated. The fore femora are dilated, and suberose along the under margin. The tibiae short, and dilated at the base and apex. The four hind legs short, with the femora denticulated beneath. Plate XXXII.

Gray, and having also before me Serville's types of his two species, C. versifasciata and C. versirubra, in the Hopeian Collection, I am able to refer the two latter to C. Goliath. The type of C. versifasciata is a smaller female, and has lost all its distinctive colours, probably from having been originally preserved in spirits of wine. I have also recently obtained a remarkably beautiful specimen of the female from Moreton Bay, of which the following are the dimensions : — Long. corp. cum operc. unc. 8^ ; cap. lin. 5 ; anten. lin. 15; proth. lin. 5; mesoth. lin. 15; metath. lin. 14y ; abdom. unc. 3, lin. 7 + unc. 1 + operc. ap. lin. 9 =unc. 5, lin. 4 ; tegm. lin. 22 ; alar, expans. unc. 8. In this specimen the mesothorax is nearly smooth ; the colour of the membranous portion of the wings is hyaline tinged with green ; the prothorax has a broad brown fascia on each side ; the abdomen is dark fulvous brown, with the extremity and the operculum dark green. The Acrophylla Typhceus of Gray, which De Haan gives as the male of Cyphocrania Goliath, is the male of Tropidoderus Childrenii. 4. (275.) Cyphocrania Beauvoisii.

Lichtenstein' s figure of this species is evidently more faithful in some respects than his description : thus, the tegmina, which he says are "brevissimis," are in fact ob- long-ovate, and as long as the metathorax ; and the fore legs are not so broad as to merit the term "latissimis." It is described as a male, and as a native of China. I can scarcely doubt, however, but that it is an African insect, of the female sex, and that it is, in fact, the female of Palophus Haworthii, ante, p. 90. The armature of the legs, the quadrinodose mesothorax, the bilobed fourth and fifth seg- ments of the abdomen, and the emargination of the terminal segment, observable in Lichtenstein's figure, are all found in the Berlin and Leyden specimens of the female, which is Burmeister's Haplopus ceratophyllus. It is indeed not improbable that the Leyden specimen may be the original Holthuysian type described by Lichtenstein. 8. (279.) Cyphocrania aestuans, Westw. Plate VII. fig. 4, female.

This fine species is nearly the size of Ph. reticulata of Palisot de Beauvois ; but the wings and wing-covers are scarcely more than half the size of those of that species. The entire insect is of an obscure luteous ashy or pale buff- brown colour, the surface having a great number of mi- nute black granules. The head is oval, with two larger com- pound tubercles between the eyes, and with small tubercles on the back part of the head arranged on each side in three longitudinal rows. The antenuse are shorter than the mesothorax, with the basal joints of moderate size. Theprothorax is rugose, and of equal length with the head. The mesothorax is armed with three or four small spines on each side of the median line, placed irregularly. The metathorax has the posterior portion greatly elongated. The abdomen is very long, and nearly equally broad, and simple, except the fourth segment, which has a double lobe on its hinder margin on the upper side ; the eighth segment is very short, the ninth truncated at its extremity ; the seventh ventral segment is but little swollen, and extends to one-third of the length of the ninth dorsal segment ; its extremity is emarginate ; the two aual styles are short and thick. The tegmina are oval, equal to the head and pro- thorax in length, with a slightly elevated space between the base and the middle. The wings are twice the length of the tegmina, extending, when closed, to the extremity of the first segment of the abdomen ; the costal area is uniform reddish brown, with the median vein furcate ; the hind area is steel-blue and glossy, with the base slightly tessel- lated with somewhat paler spots. The fore legs are long and nearly simple. The four hind legs have the femora furnished near the base and apex beneath with a small lobe, also on the upper side near the base and in the middle ; the tibise have two lobes before and beyond the middle on the outer edge, and a small one on the inner edge towards the base ; the tarsi are simple. The legs are slightly banded with dark brown. A specimen in the British Museum has the fore and middle legs on the right-hand side imperfectly developed. Plate VII. Fig. 4.

The head is oval, granulose, with two pairs of rounded tubercles on the crown. The antennae are broken at the tips, twenty-six joints only remaining. The meso- thorax is long, granulose, and armed with two diverging black spines near the middle of the disc. The basal seg- ments of the abdomen are narrowly margined at the sides ; the fourth has a transverse membrane near the tip ; the three terminal segments are narrowed, rugose, the terminal one entire ; the anal styles very short. The operculum slightly boat-shaped, not extending to the tip of the abdo- men. The tegmina are oblong-ovate, with a strong carina running from the base, forming an elevated lobe before the middle. The costal area of the wings is pale greenish brown ; the base paler, with a large irregular black spot ; the posterior area brown, with irregular fasciae of pale spots, and also with small round pale spots upon the longitudinal veins. The legs are strong ; the femora dentated ; the fore tibiae with an elongated membrane on the upper edge, reaching from the middle to the extremity, with two inci- sions ; the four hind tibiae have a single spine on the outer edge near the base, and with several on the inner edge ; the tarsi are compressed.

Westermann Havnise. The male of this handsome species is unique in the splendid cabinet of M. Westermann of Copenhagen. It is long and slender, and of a brown colour varied with luteous. The head is oblong ; eyes prominent ; ocelli obsolete, the hind part raised into a transverse row of very small eleva- tions ; on each side behind the eyes is a longitudinal luteous stripe. The antennae are long and slender ; beyond the middle they are slightly marked with pale rings placed wide apart. The prothorax is armed with two pairs of spines, one at the fore margin, the other in the middle. The mesothorax is also armed on its upper surface with a series of still larger acute spines, arranged not quite regu- larly in pairs. The tegmina are small, subovate, with the median carina suddenly, but only moderately, elevated into a small conical tubercle ; they are greyish luteous, with brown veins. The wings are large ; they are of a pinkish- white colour, varied with a number of irregular broad greyish-brown fasciae, the veius in the dark parts being much darker ; the costal area is huffish brown, slightly varied with brown and luteous, with the veins blackish, the median one being simple. The legs are long, slender, and unarmed, fulvous-coloured varied with brown. The abdo- men is long and slender ; the sixth segment constricted in the middle, carinated along the centre ; the seventh seg- ment shorter and subcorneal, the eighth considerably con- stricted in the middle, and the ninth subquadrate, slightly emarginate at its apex, the anal styles not being visible from above ; the terminal ventral segments are considerably swollen, the ninth extending only to the extremity of the eighth dorsal segment, acute, with the tip also emarginate. The meso- and metasterna are spinulose. Plate XXXVIII. Fig. 2. The male, of the natural size. 2 o. The terminal segments of the body seen sideways. 11. (282.) Cyphocrania? punctipes.

Entirely smooth and rather glossy, except the mesotho- rax, which is more or less covered with small, oblong, slightly raised tubercles, especially in front, and along the lateral margins of the upper part ; the general colour is pale green, with the mesothorax and abdomen brownish, the latter greenish at its extremity ; the tegmina and costal area of the wings are green, the membranous portion of the latter slightly stained with brownish, with longitudinal fulvous veins. The head is oval. The antennae short, with about twenty-three joints ; the basal joint of moderate size. The prothorax is scarcely larger thau the head, its anterior lateral angles narrowed and slightly porrected ; the disc PIIASMIDJE. ACROPHYLLA. 113 uneven. The mesothorax has its sides nearly straight ; the mesonotum is, however, narrowed behind to the base of the tegmina, which, when closed, do not extend over more than two-thirds of the metanotum ; they are shortly ovate and strongly reticulated, and rather more than half the length of the wings, which, when closed, extend to the middle of the second abdominal segment. The abdomen is long, simple, and subconvex ; the segments gradually narrowed to the extremity and margined at the sides, the anterior ones with two lines of small impressions on each side ; the terminal segment is rounded, exposing the two small styles as well as the extremity of the operculum, which is con- stricted close to the base. The legs are short, strong, and angulated ; the middle ridge of all the femora beneath armed with a few slight and scarcely distinct spines. The specimens from the Philippine Islands have the me- sothorax more strongly granulated. Plate IV. Fig. 2. The female, of the natural size. 2 a.

This species is closely allied to PL Alpheus, but is at once distinguished by the relative size of the wing-covers and wings, more slender abdomen, smooth mesothorax, and denticulated femora. The head is obovate and convex, very smooth ; it is produced into a prominent angle in front of each eye, behind each of which is also a slightly curved longitudinal impressed line. The antennae are rather longer than the pro- and mesothorax ; the first joint moderately robust, the third and immediately following joints very short, but gradually elongated. The prothorax is marked on each side of its hinder portion with a slightly impressed oval line, each preceded by strong punctures. The meso- thorax is smooth and oblong, with a slender raised line running along each side to the base of the wing-covers, this line being punctured on its inner edge ; near the hind margin it has two deep impressions, between which is a minute scutellum-like plate. The abdominal segments are smooth and nearly square, each slightly constricted at its base and apex ; the eighth and ninth joints attenuated, the latter angulated along the middle of its upper surface. The operculum is constricted near the base ; it is boat- shaped, and extends very slightly beyond the extremity of the ninth dorsal segment. The anal styles are short, broad, and obtuse. The tegmina are oval, pale green, very strongly and thickly reticulated, the membrane along the anterior and posterior edges towards the base being brown ; the strong discoidal vein is slightly elevated. The wings have the costal area pale luteous at base, greenish at the apex ; the veins more strongly coloured than the membrane ; the chief vein is furcate both towards the base and about the middle of the wing ; the hind portion is pale luteo-fulvous, with the longitudinal veins fulvous, the transverse ones nearly colourless. The legs are short and strong ; the femora finely spined beneath. The unique specimen in the British Museum has the left fore-leg not fully developed. Plate XXVII. Fig. 5.

Inhabit New Holland. The Australian species here brought together form several divisions, according to the size of the wings. Thus, in Act. Titan they are of large size in the female, whilst in Acr. Chronus, &c. they are much shorter in the female. A. violascens is destitute of ocelli . De Haan unites A. 11-1 CATALOGUE OF ORTHOPTEROUS INSECTS. Titan with Cyph. Goliath in the genus Cyphocrania ; but the remarkably elongated anal appendages refer the former species to Acrophylla, whilst G. Goliath, from the arma- ture of its legs, and greatly elongated ovipositor, evidently belongs to a type distinct from the true Acrophylla. 1. (289.) Acrophylla Titan. Mas.

I am not satisfied as to the amount of variation to which this species is subject, but believe it to be greater than would at first sight be credited. In the Hopeian Collec- tion are preserved a male and female, received from Mr. MacLeay as distinct, under the name of Diura Saturnus ; the female agreeing with Gray's figure in the size of the wings and tegmina, but with the legs and anal styles more elongated, the latter being 13 lines long, the entire insect being 8 inches long. Other female specimens, of much smaller size, varying from 5 to 6 inches long, have the wings scarcely so long as the tegmina. In these also there is considerable difference in the length of the anal styles. Another specimen, about 8£ inches long (including the anal styles, 13 lines long), has the wings as large as in Gray's figure, but much more strongly tessellated than the ordinary individuals, the general colour of the specimen being reddish brown. 4.

This species is remarkable for having the wings strongly tessellated in both sexes, those of the female being scarcely more than half the size of those of the male, and for the minute size of the anal styles of the male. The body is long and slender. The general colour is dark reddish brown. The head of the male is wide, with large eyes, and the three ocelli are distinct in both sexes ; the antennae in the male are moderately long, slender, and finely setose, about 24-jointed ; those of the female are much shorter, but composed of the same number of joints. The meso- thorax is armed along its upper surface with about six pairs of small pointed tubercles, placed rather irregularly ; and the lateral margins are also armed with a few smaller ones. The tegmina are oblong-ovate, with the middle of the central carina scarcely elevated. The wings are white, Q2 116 CATALOGUE OF ORTHOPTEROUS INSECTS. strongly marked with black-brown tessellations along the transverse veins ; the costal area is red-brown, with the numerous transverse veinlets whitish ; the central vein is furcate near the base. The legs of the male are long and slender, shorter and more robust in the female ; the ante- rior pair nearly simple, but the four hinder with the lower angles (especially of the femora) finely serrated. The ab- domen of the male is long and slender ; the terminal ven- tral segment short and much swollen ; the terminal dorsal segment contracted at the base, swollen at the sides, and furcate at the extremity, with minute teeth at the inner edges of the furcation. The ovipositor of the female is boat-shaped and compressed, followed by two compressed porrected anal styles about as long as the preceding joint. Plate XXXV. Fig. 1 .

I have only seen the male of this species, which is very long, slender, and cylindrical, entirely of a luteous pale brown colour (the specimen had, however, been preserved in spirits of wine). The head is rather large and subdepressed ; the eyes very large, as well as the three ocelli. The antennse are short and thick, 23-jointed, the joints narrowed at the base, and setose. The mesothorax is long, armed with four pairs of short thick spines. The tegmina are elongate- ovate ; the median carina moderately elevated. The wings are large, stained along the outer margin with darker brown; the costal area darker, especially along the basal half, with the median vein furcate near the base. The abdo- men is very long and slender ; the last joint truncate, with the truncation curved ; the anal styles as long as the three terminal joints, flattened, and slightly pointed at the tip. The legs are of moderate length and serrated, the anterior tibice being simple ; the four hind tibiae with a bispinose foliaceous lobe near the base on the upper edge. Plate XXXVII. Fig. 2.

The head is oblong and polished ; the eyes large, as well as the three ocelli. The autennse are long and straight, about 24-jointed, the joints being remarkably long. The anterior half of the body is of a rich fulvous colour ; the legs rather paler, with a slight greenish tinge. The prothorax is rather irregular on its upper surface, and the mesothorax is marked by an impressed line down the whole of its length. The tegmina are small, oblong, with the middle of the carina but slightly elevated ; they are fulvous yellow, with the inner margin marked with three rows of small black spots occupying the areas between the transverse yellow veins. The wings are large, of a beau- tiful rosy hue, with darker rosy longitudinal veins ; the costal area rich yellow, with fulvous longitudinal veins ; the fore margin tinged with green, and the hinder margin with a brown dash, intersected by the pale longitudinal veins ; the principal vein is not furcate, but it unites before reaching the apex of the wing with the next vein, and this united portion again unites close to the tip with the fol- lowing vein. The legs are very slender and simple ; the basal joint of the tarsus about as long as the following joints united. The abdomen is long, cylindrical, brown, and polished ; the three terminal joints are short, and termi- nated by two slender, straight, porrected styles ; the ovi- positor is straight, scarcely swollen, and reaches to the extremity of the ninth dorsal segment.

Hab. In Columbia (D. Gaudichaud). In Mus. Saun- ders. This species is long and slender, of an obscure blackish- brown colour, opake. The head is nearly square, but slightly convex, with the three ocelli on the crown, the an- terior one considerably in advance of the others ; on each side behind the eyes is an obscure pale streak . The antennae are long and slender ; the joints are very long, and each alternate joint has its base marked with a broad whitish ring ; beyond the middle each joint is composed of a great number of minute articulations. The prothorax is oval, the anterior angles being truncated and spiraculiferous. The mesonotum is scarcely longer than the prothorax, finely rugose, and with two oblique rows of small tubercles on each side extending to the insertion of the tegmina ; the latter are small and nearly square, the centre strongly ele- vated into an obtuse angle, the ridge of which is marked with a dull whitish line. The wings are large, opake whitish, with a slight fulvous tinge, which is the colour of the longitudinal veins ; the veins and veinlets along the outer margin of the wings are brown ; the costal area is blackish, with the principal vein furcate near the base. The abdomen is long, narrow, of nearly equal width through- out ; the terminal ventral segments considerably swollen and angulated, not extending beyond the eighth dorsal segment ; the anal styles deflexed and ovate. The legs arc long and slender, destitute of spines ; the basal joint of the tarsi is as long as the three following joints. Plate XVII. Fig. 2. The male, of the natural size. 2 a.

This species is well distinguished by its short and bi- spinose mesothorax, and by the peculiar markings of the costal area of the wings. The general colour is dark brown variegated with olivaceous green. The head is very convex behind, and raised into a large conical tubercle ; the three ocelli are very large. The antennae are pale luteous, very long and slender, but only 24-jointed ; the apical joints are, however, finely and minutely annulated ; each joint has the apical half brown. The mesothorax is very little longer than the prothorax, armed before its middle with two erect obtuse points, preceded by two more minute ones ; its lateral margins are also armed with two or three small spines. The tegmina are larger than the mesothorax ; the central carina is very strongly elevated and rounded, the apex is obliquely truncated, and the disk strongly reticulated with the fine pale veinlets. The wings are large ; the costal area pale olivaceous green, with numerous irregular-sized broad brown waved spots ; the chief vein is furcate near the base ; the hinder area smoky coloured, with darker longitudinal veins. The abdomen is dark brown ; the terminal segments short, and conical at the tip ; the oviduct small, but reach- ing to the extremity of the abdomen ; the two anal styles short, obtuse, setose, and convergent at the tip. The legs are long, slender, and simple, alternately marked with brown and olivaceous spots ; the tarsi are long, the basal joint being about as long as the three following joints. Plate XXXIII.

Ega, in Brasilia (B. Bates). B.M. Of this elegant species I have only seen a single speci- men, which I regard as a female with some doubt. The anterior part of the body is grass-green, with purplish- brown markings, the mesothorax and abdomen being lu- teous brown. The head is oblong and green, with a cir- cular yellow patch between the eyes surrounded by a black ring, and having a slender dark line down its middle ; the hind part of the head is marked with seven longitudinal pale yellow lines. The antennse are reddish brown, the tips of the joints darker, basal joint yellow. The pro- and me- sothorax are green, with several dark purplish-brown longi- tudinal lines with slender yellow ones between them, the sides of the latter grass-green. The tegmina are elongate- ovate ; the carina scarcely elevated in the middle ; the inner margin, and a patch extending from it to the middle of the carina, of a purplish-brown colour. The wings are large and white, the longitudinal veins slightly fulvous ; the costal area has its anterior half grass-green, the posterior half yellowish, with irregular purplish-brown patches ; the me- dian vein is furcate. The legs are short and simple ; they are greenish-luteous coloured, with the tips of the femora and tibiae dusky. The abdomen is long, and of a luteous- brown colour ; the three terminal joints are rather short, and gradually attenuated, with the anal styles porrected and obtuse : the operculum is not at all prominent, and scarcely extends beyond the extremity of the seventh dorsal segment ; it is pointed at the tip, and is followed by two flattened plates united by a straight line down the middle, and these again by an entire, oval, slender membraue.

The head is subquadrate, its ante- rior part pale yellow ; eyes prominent ; ocelli three, luteous. The head, prothorax, mesothorax, tegmina, legs, and costal area of the wings are greenish ashy, not glossy ; the an- terior parts of the body rugose, with minute pale granula- tions. The antennae are nearly as long as the body, with pale annuli ; the mesothorax is short, as well as the meta- thorax, being of nearly equal length. Tegmina small, sub- ovate, rugose ; the carina moderate, armed near the base with a small erect spine. Wings with the costal area ashy green, the principal vein furcate, hinder portion of wings slightly tinged with brown. Abdomen long, slender, dark brown, slightly glossy, rather clavate at the tip ; apical dorsal segment with a small notch in the middle of the hind margin ; anal styles short and rather thick ; terminal ven- tral segments scarcely swollen, extending rather beyond the base of the ninth dorsal segment.

The female, as will be seen from the measurements given above, is considerably larger ; the spine on the tegmina of the male is not so large, and is more deflexed than in the female ; the antennae of the male are very long and slender, consisting of about forty joints, the joints long and slender, slightly hairy, and scarcely distinguishable from each other ; near the extremity of the antennae in the female there is a white annulus about a line long ; the costal area of the wings in the female is greenish brown, with a few slightly- marked pale spots near the apex, none of which are dis- cernible in the male ; the posterior area is of a dirty huffish white, with buff veins. The legs are dirty brownish green, with the femora and tibiae darker at the tips ; the ante- rior and middle tibiae are also slightly marked with paler annuli. Pi.ate XIII. Fig. 3.

The head is furnished in the male with three rudimental ocelli, which are almost obsolete in the female. The antennae are long r 2 124 CATALOGUE OF ORTHOPTEROUS INSECTS. in both sexes. The tegmina are oval, and have a large dark central patch, the middle of the central carina being but little elevated ; the principal vein of the costal area in the wings of both sexes is furcate near the base ; the trans- verse, veins in this part are rather wide apart, and black. The wings of the male are of full size, but those of the fe- male are scarcely longer than the mesothorax. The abdo- men of the male is cylindrical, with the seventh and eighth segments rather swollen ; the terminal ventral segment does not extend beyond the eighth dorsal, and is not swollen and more membranous than usual ; the last dorsal segment is small, and arched at its extremity, with the anal styles short, cylindrical, obtuse, and setose ; the abdomen of the female is longer and more robust, the sixth ventral segment with a short spine in the middle of its posterior margin ; and the oviduct is membranous, and does not extend be- yond the middle of the eighth dorsal segment. 23.

Villa Nova, in Brasilia (D'. Bates). B.M. This obscurely-coloured, very slender species is well distinguished by the very short legs, annular antennae, and granulated anterior part of the body. The head is small, oblong, convex ; eyes very globose and prominent ; between them in the male is a circular depression, within which the ocelli are placed; the two posterior ones on raised pale- coloured tubercles, giving the appearance of a pair of greatly enlarged ocelli. In the female the ocelli are small and less conspicuous. The antennae are slender, about 50-jointed, brown, with the majority of the joints pale at the base ; the terminal joints are very indistinct, and close to the tip is a rather broad white ring. The pro- and mesothorax are finely but rather distantly granulose. The tegmina are small, oval, with the veins strongly marked, and with a moderately ele- vated tubercle a little before the middle of the chief vein. The wings are rather long and narrow, equally developed in both sexes, stained pale brown, with the veins rather darker ; the costal area pale luteo-greyish, varied with darker purplish-brown clouds ; the principal veins marked alternately with short black streaks ; median vein furcate at about one-fourth from the base of the wing. Legs, especially the four hind ones, very short, slender, and simple. Abdomen very long and slender, the terminal seg- ments in the male not dilated above, and scarcely so beneath, widely gaping at the tip ; anal styles small, and buff. The terminal ventral segments, in the only female I have seen, may possibly have been injured, — the plate analogous to the oviduct being flattened, and only extending to the extremity of the seventh dorsal segment, and notched at its tip, fol- lowed by two pairs of lateral compressed plates, narrow, and pointed at the tip, and another bifid flattened plate with the two anal styles. Obs. One of the specimens of the male, received with the rest from Mr. Bates, is destitute of ocelli (fig. 2d). Plate XXI. Fig. 2. The female, of the natural size. 2 a.

This is one of the most curious species in the family, and is distinguished not only by the brilliancy of its colours, but also by its remarkably short mesothorax, scarcely more than a quarter of the length of the metathorax, its straight anterior femora, large subglobose head, large wings, &c. The head is large and fulvous red, with three ocelli in a triangle between the eyes. The antennae are long and slender, with several broad whitish annuli. The prothorax brown, with two pairs of black patches on the back ; the anterior lateral angles are circularly incised. The meso- thorax is very short, gradually raised and widened behind. The tegmina are pale reddish brown, with minute dots of black in the reticulated spaces. The wings are large and bright orange-coloured, with a broad black border, the tip being pale lutcous ; the costal area is reddish brown, with a multitude of minute black dots within the reticulated spaces; the chief vein is furcate near the base. The meta- thorax is wide ; the abdomen gradually narrowed to the tip, dark brown-coloured ; the three terminal segments short, entire ; anal styles short, exserted ; operculum moderately swollen, extending to the extremity of the abdomen. Legs moderately long, slender, and simple ; femora blackish ; tibiae and tarsi annulated with luteous and blackish. Tarsi with the basal joint rather longer than the three following joints united. Body beneath of a nearly uniform rich brown colour. Plate XVII. Fig. 5. The female, of the natural size. 5 a. The terminal segments of the abdomen seen sideways. 26. (327.) Phasma unicolor.

The only specimen I have seen of this species has the abdomen broken off beyond the third segment, so that it is only from its slender form that I conjecture that it is a male. It is slender and cylindrical, dusky brown, and desti- tute of gloss. The head is rather larger than the prothorax ; eyes prominent ; the middle of the head rather rugose, and with two rows of granules extending towards the hind mar- gin. The antennae are very long and slender, brown, with paler annulations. The mesothorax is long, slender, and finely granulose. The tegmina are ovate, considerably shorter than the metathorax, with the apical margin ob- liquely truncate ; they are brown, with darker veins, and with a strongly elevated tubercle towards the base. The wings are of moderate size, slightly stained with brown, with dark brown longitudinal veins ; the costal area pale brown, with numerous darker small patches and spots, especially towards the disc of the wing ; the chief vein is furcate. The abdomen is long and slender. The legs are of moderate length, slender, simple, dusky, and slightly varied with paler dots. Plate XVII. Fig. 1. The insect (male?), of the natural size. 28. (329.)

This species approaches Ph. brevipenne, Burm. ; but that species is described as possessing ocelli, and as having the wings three times as long as the tegmina, the latter being mucronated in the middle ; in all which respects it differs from the one now under notice. The body is long, rather slender and subcylindrical, of an obscure blackish colour with a greenish tinge ; the head and thorax covered with small granules ; the abdomen rugose. The head is rather wider than the prothorax ; the eyes moderately pro- minent, without ocelli ; the crown of the head with two small spines on each side. The antenna; reach to the middle of the metathorax ; they are 20-jointed, the joints being long. The tegmina are elongate-ovate, rather narrow be- hind ; they are of a dark greenish colour, with darker veins ; the carina is strongly elevated near the base into a rounded lobe. The wings are about twice the length of the tegmina, with the costal area ashy green, the base pale obscure rosy ; the posterior area smoky, with pale strigse between the transverse veinlets. The abdomen is long, with the sixth and seventh segments dilated, and the eighth and ninth narrowed, the last being longitudinally carinated above, the carina terminating in a rather deep incision ; anal styles short, obtuse, and slightly protruded ; the seventh ventral segment is strongly angulated. The legs are rather short ; the anterior femora rather dilated and rugose ; the basal joint of the tarsi not longer than the three following joints. Plate XI. Fig. 5.

This is a very curious species, distinguished by its ro- bust body, very short mesothorax, and very long simple legs and antennae. The head is rounded, convex, entire, with three very minute ocelli ; the eyes very prominent. Antenna long, slender, and multiarticulate, every fifth or sixth joint being separated more distinctly from the follow- ing than the others, making, at first sight, the antenna appear as if composed of long joints each reducible into several subarticulations. The prothorax is subcorneal ; the anterior lateral angles semicircularly truncate ; the hind margin with a broad black transverse fascia. The meso- thorax is short, broad, subcorneal, and simple. The teg- mina are small, subovate, emarginate on the hinder margin, the reticulations pale-coloured ; the central carina but little elevated. The wings are very wide ; the costal area dark brown, with very numerous transverse parallel luteous veinlets ; the main vein furcate near the base, the two divi- sions uniting together again near the tip ; the hinder area is smoky- coloured, with brunneous longitudinal veins. The abdomen is robust, swollen in the middle, and convex ; the three terminal segments narrow, the eighth moderately elevated ; the operculum boat-shaped, deepest near the base ; the anal styles short and porrected. All the legs are long and simple; the tarsi long ; the hind ones two thirds of the length of the hind tibia. Plate XVII. Fig. 3. The female, of the natural size. 3 a.

Body long and slender, generally simple, or occasionally with the head, prothorax, mesothorax, or tegmina spined, and with short quadrate tegmina and fully developed wings in both sexes. Head generally unarmed, with or without ocelli. Antenna; generally very long, and often annulated. Thorax elongated, cylindrical. Mesothorax generally about thrice the length of the prothorax or shorter (in the species destitute of ocelli). Tegmina small, generally subqua- drate, and from one-fifth to one-eighth of the length of the wings. Wings large ; costal area with the main vein sim- ple in both sexes, or bifurcate in the female only of some of the species. Legs long and slender, neither spined nor dilated ; basal joint of the tarsi very elongate. Abdomen elongate, cylindric, subclavate in the males ; anal styles very short. Inhabit India and the Islands of the Eastern Ocean. Restricted as this group is, according to the views of Serville and De Haan, to the Oriental species allied to Phasma, the species are very numerous. In the following arrangement I have not attempted to tabulate the species, although I have followed the distribution proposed by De Haan, commencing with the species with spines on the head, after which are placed some species with spines on the thorax, followed by the unarmed species having an elon- gated mesothorax. De Haan has distributed the latter according to the colours of the wings and legs, which has led to artificial results. The genus is terminated by those species which have the mesothorax comparatively short. 1. (334.) Necroscia spiniceps.

In Mus. Lugdunensi. This is a very slender and delicate species, well distin- guished by its conically elevated head and short truncated tegmina, with the hind margin pale green. The head is much larger than the prothorax ; the three ocelli distinct. The antennae in the male are longer than the entire body, blackish, with a white ring near the tip. The antenna: and legs of the female are shorter than those of the male. The pro- andmesothorax are slender, but widened behind; the disc covered with minute white granules. The tegmina are very short, with a strongly elevated conical tubercle in the middle, the hind margin narrowly edged with pale green. The wings are dusky ; the costal area in the male reddish and unspotted, in the female reddish brown with numerous darker clouds ; in the former the principal vein is simple and pale-coloured, but it is furcate in the latter. The abdomen is very long and slender in the male ; the eighth joint longer than the preceding or following, the latter being very short ; the three terminal ventral seg- ments are considerably dilated, the ninth extending to the extremity of the eighth dorsal segment. In the female the abdomen is more robust, with the operculum extending to about the extremity of the eighth dorsal segment. The legs of the male are very slender and reddish, the tarsi whitish, with the base of the first joint dusky ; the legs of the female are shorter and more obscure, but with pale tarsi, the basal joint being about half the whole length of the tarsi.

The head and thorax are dull pale greenish and finely granulated, the remainder of the body brownish and smooth ; the head is armed on the crown with about ten erect spines. The antennas are about two-thirds of the entire length of the body ; they are obscurely co- loured, with a slight pale annulus near the tip. The pro- thorax is small, with a few small erect spines across the hinder margin, The mesothorax is armed in front with two pairs of strong spines (those on the left side being con- fluent, except at the tips, in the only specimen which I have seen) ; the disc of the remainder of the mesothorax is armed with a few much smaller spines. The tegmina are small and subquadrate, with a strongly raised obtuse tu- bercle in the middle ; the hinder margin with two pale spots on the edge. The wings are brown ; the costal area darker, with several small pale spots on the fore margin, and two or three larger and more distinct near the tips. The abdomen is very long and slender, the fifth segment with its hinder edge elevated in the middle ; the three ter- minal segments rather swollen, the last emarginate at the tip ; the two terminal ventral segments are swollen, the last not extending beyond the extremity of the eighth dorsal segment. The fore legs are wanting in the speci- men drawn ; the four posterior are rather short and simple, obscurely coloured, with the tips of the femora and tibiae darker ; the basal joint of the tarsi is not more than half the whole length of the latter.

This obscurely-coloured species is easily distinguished by its conical head, short legs, and rather thickened hind thighs. The general colour is obscure brown, slightly varied with buff and luteous. The head is conically ele- vated in the hind part of the disc, the surface being armed with acute granulations ; the face is marked with a small triangular black spot. The antennae are long and slender, multiarticulate, finely setose, the joints very short. The pro- and mesothorax are slender and finely granulose. The tegmina are small and ovate ; the median carina rather strongly angulated between the middle and base ; the chief veins are varied with buff and black spots ; they are not straight, but slightly undulated throughout their whole length. The wings are moderately large, stained blackish brown, with the longitudinal veins somewhat darker-co- loured ; the costal area is darker brown, the chief vein not furcate, blackish, with numerous small luteous dots. The abdomen is long, slender, and simple; the terminal segments, especially the eighth, strongly elevated and angulated at the summit, the ninth joint obliquely deflexed ; the three terminal ventral segments are not swollen beneath, the ninth extending beyond the extremity of the ninth dorsal segment. The legs are slender and short, resulting chiefly from the shortness of the tibia?, which are not so long as the femora ; the hind femora are rather thickened and den- ticulated along their whole length ; the basal joint of the tarsi iu all the legs is about the length of the three follow- ing joints united.

Sarawak, Borneo (D. Wallace). In Mus. W.W. Saunders. This species is at once distinguished by the great length of the abdomen and the comparative shortness of the me- sothorax, with its recurved spines. The head is rather flat and simple ; the three ocelli are very minute, but distinct. The antennae are very long (at least 4 inches) and slender. The prothorax is the same size as the head. The mesothorax is about 2-i- times the length of the pro- thorax ; it is rather narrower than the prothorax in front ; its disc is rather flat, each side having about eight thin acute recurved spines. The metathorax is oblong, wider than any other part of the body, its hinder portion rather longer than the anterior. The abdomen is long, narrow, and simple (twice the length of the entire thorax) ; the three terminal segments are widened (they have, however, been crushed) ; the seventh and following ventral plates extend only to about the middle of the eighth dorsal segment. The anal styles are short and obtuse. The teg- mina are short, broad, and subtruncate at the extremity. The wings are large ; the anterior area pale dull green, the median vein furcate ; the posterior area is pale brown, with a large, somewhat triangular pale buff spot near the apex. The legs are long, slender, and simple ; the femora finely serrated ; the tarsi with the basal joint as long as all the remainder together. The body beneath is pale and simple, except the mesosternum, which has two rows of deflexed spines. The pupa is smaller (3£ inches long), with the meso- thorax similarly spined ; the rudimental tegmina are very minute (about one line long), oval, and the rudimental wings are subovate, 5-J lines long, touching each other along the inner margin in the middle of the back.

This obscure species is distinguished by the granulose surface of the anterior part of the body, and by the ante- rior half of the mesonotum being armed with six small black spines arranged irregularly in pairs. The head is oblong, PHASMIDJS. NECROSCIA. 131 with an oblong impression between the eyes ; the granules on the hind part of the head are arranged in longitudinal lines. The antennae are long and slender, with the joints short, but irregular. The mesothorax is of equal width with the head, with a slightly raised longitudinal dorsal median line. The tegmina are small, oblong-quadrate ; the median carina slightly indicated, with the ordinary conical elevation almost obsolete. The wings are long and rather narrow, subhyaline, with the longitudinal veins luteous brown ; the costal area greyish brown, the median vein simple and paler coloured. The abdomen is long, subcylin- dric, with slightly raised longitudinal lines along the lateral margins ; the apex gradually attenuated and simple, the tip trilobed, the middle lobe rather elongated and rounded ; the anal styles short, porrected, and conical. The ovi- duct scarcely swollen, extending to about the middle of the ninth dorsal segment.

This species, of which I have only seen a single speci- men of the male, approaches N. JEsalus, of which it might at first be supposed to be the opposite sex ; the armature of the head and legs seems, however, sufficiently to disprove this relationship. The head is nearly ovate ; the eyes mode- rately prominent ; the ocelli wanting ; the inner margin of each eye is armed with two small spines, and the hind part of the crown of the head is raised into a rugose tubercle armed in front with minute spines. The mesothorax is rather short and subrugose. The tegmina are nearly square, with the costa elevated into a strong crest, rounded in front. The wings are large and pale, with the costal area darker and clouded. The abdomen is elongated, as wide as the mesothorax ; the fourth, fifth and sixth segments a little dilated at a short distance from the base of each ; the seventh and eighth short, and rather wider than the preceding ; the ninth subquadrate, rather constricted in the middle on each side, with the apical angles rounded off, and the hind margin emarginate in the middle. The anal styles are short, obtuse, and not exposed ; the three terminal ventral segments are short, only extending to the base of the ninth dorsal segment ; they are moderately swollen, the eighth being very short and transverse. The legs are rather short and robust ; the four posterior femora witli two or three mi- nute spines on the under side near the tips ; the basal joint of the tarsi is not longer than the three following joints.

In insula Java (Dr. Ilorsfield). In Mus. Soc. Merc. Ind. Orient., Lond. The only female specimen which I have seen of this spe- cies very closely resembles Necroscia Salmanazar (PI. XVI. fig. 6) in its general form and proportions, but differs in its uniform fulvo-luteous colour, in the possession of three distinct, although small, ocelli, in the more strongly granu- lose mesonotum, in the uniform colour of the costal area of the fore wings, and in the two small horns with which the sixth ventral segment is armed at its extremity. The head is rather longer than wide, with a slight circular impression between the eyes, within which the ocelli are placed ; the hind part of the head is slightly raised, and divided by a longitudinal impressed line down the middle. The antenna; are very long and slender, with very numerous joints scarcely discernible. The mesonotum is covered above with minute granules, without any raised longitudinal carina. The tegmina are small, oval, obliquely truncate at the ex- tremity. The wings are large, somewhat hyaline, and co- lourless ; the costal area pale fulvo-luteous; the median vein concolorous with the body, simple, and rather darker than the remainder. The abdomen is wider than the thorax, nearly parallel ; the last three dorsal segments short ; the terminal one emarginate, exposing a minute rounded lobe at its apex ; the anal styles are of moderate size, concolo- rous, porrected, and resembling a small open forceps ; the sixth ventral segment has a small deflexed spine on each side at its extremity ; the operculum is nearly straight and compressed, its apex acutely bifid. I have not thought it necessary to give a figure of this insect, as it bears so great a general resemblance in its form and proportions to Necroscia Salmanazar. 19. (352.) Necroscia Aruana, Westw.

Sarawak, Borneo (/>. Wallace). B.M. This obscure species is well distinguished by the short multi-sinuated femora and tibiae, as well as by the sub- lineated granulation of the mesonotum. The head is nearly square, slightly elevated at the hind part, and gra- nulose. The antennae are long and very slender ; the joints short. The mesothorax is gradually broadened behind, being wider than the head at its base ; the granules are larger than on the prouotum, especially those towards the fore part, where they form several irregular lines. The tegmina are oval, with the subbasal elevation of the median carina slightly marked ; the veins are not very prominent, but are marked with several short whitish spots. The wings are of moderate size, brownish, with the longitudinal veins darker brown ; the costal area is obscure and darker brown, varied, especially towards the extremity, with greyish buff ; the chief vein is simple, varied with brown and luteous. The abdomen is wider than the mesothorax, of nearly equal width throughout, each of the six basal segments being rather dilated on each side towards its base ; the three ter- minal segments are gradually narrowed ; the seventh and eighth with an elevated tubercle near the middle of the hind margin. The ovipositor is conical, depressed, with a curved carina on each side from the base to the middle, enclosing on each side a raised polished spot, giving to the ovipositor, when seen from beneath, the appearance of a fox's face, the nose or tip of the ovipositor being slightly emarginate. The legs are rather short ; the femora and tibiae (except the tibiae of the fore legs) rather dilated, and multisinuated along their whole length ; the basal joint of the tarsi is simple, and about as long as the three following joints.

This male species, of which I have seen but a single in- dividual (interesting on account of the partial development of one of the fore legs), is long, very slender, and cylindric, with the body entirely smooth, except the mesothorax, which is very finely granulose throughout its entire sur- face. The head is nearly square, but slightly convex, with two minute black dots between the eyes, and a fine im- pressed line down the middle of the back of the head, ex- tending also through the pronotum ; the mesouotum having a fine central carina. The antennae are long and very slender, each composed of about seventy joints, each fourth joint being black ; the remaining joints being of the general colour of the insect, which is of a luteous brown. The tegmina are small and nearly square ; the central carina elevated into a conical tubercle towards the base. The wings are large and somewhat hyaline, slightly stained with brown, with pale brown veins ; the costal area tinged with rosy brown, and varied with darker rosy-brown irre- gular and ill-defined spots, especially in the middle of the fore margin, the chief vein being also dotted with brown. The abdomen is long and simple ; the three terminal seg- ments slightly dilated, the last quadrate, with the extre- mity truncate and much deflexed ; the three terminal ven- tral segments extend to the extremity of the body, and are but slightly swollen beneath. The legs are short, slender, and simple, except the femora, which have a minute spine on the under side near the tip ; the basal joint 'being as long as all the rest united. Plate XII. Fig. 2.

Long, slender, subcylindrical ; the female more robust, with the hind part of the mesothorax and the metathorax dilated. The general colour of the head and thorax is ful- vous or luteous, varied with dark brown markings. The head is unarmed, and furnished with two small round tubercles between the eyes, which appear to be developed into ocelli in the male ; the hind part of the head is marked with eight more or less distinct dark lines. The antenna? are very long and slender (one-fourth longer than the entire insect in the male) ; the basal articulations are luteous ; at the distance of half an inch from the base the joints be- come very short, a single joint at equal distances apart (about « quarter of an inch) being pale at its base, and there being also a ring of white near the tip. The pro- thorax is marked with two rather angulated lines down the middle. The mesothorax is marked with several dark patches, especially one on each side near the tegmina ; its disc is covered with small luteous granules. The tegmina are subquadrate, with the carina moderately elevated in the middle into a rounded lobe ; they are black, with the lateral margin and the fine reticulated veins green. The wings are long and rather narrow ; the costal area is green, with the veins (both longitudinal and transverse) paler, marked with a number of dark brown clouds forming indi- stinct fasciae ; the chief longitudinal vein is simple. The posterior area is brown, more or less strongly tinged with rosy red. The legs are luteous buff, with dark brown rings ; they are slender and simple, with the basal joint of the tarsi long, and pale yellow, with the tip black. The abdomen is brown, with the articulations paler ; that of the male is very slender, with the three terminal segments rather short and slightly swollen ; the last segment attenu- ated and notched at the tip ; the three ventral segments are moderately swollen, extending a little beyond the base of the ninth dorsal segment. The terminal segments of the female are simple, the operculum extending to half the length of the ninth dorsal segment. Plate IX. Fig. 1. The male, of the natural size. 1 a.

The head is sub- quadrate, the hinder part not at all elevated. The eyes rather small, but very prominent. The antennae long, slender, and blackish. The mesothorax finely granulated above, about four times the length of the prothorax. The tegmina obscure greenish, small, oval, scarcely carinated, and but slightly angulated towards the base. The wings are scarcely stained with brown ; the costal area is greenish brown, paler green along the inner margin ; the veins dark, the principal ones varied with minute whitish spots ; the second vein is not furcate. The abdomen is very long and slender ; the terminal segments rather widened, but not swollen, the last with the edges deflexcd at the tip, and armed with minute teeth on the inside ; the anal styles are thickened, and obtuse at the tips ; the terminal ventral segments have, I believe, been injured in the unique male which I have seen. The legs are long and slender ; the middle ones considerably the shortest, simple, except that all the femora are armed on the under side near the tip with a small spine ; the basal joint of the tarsi is about as long as the succeeding joints united.

The female also bears a considerable resemblance in general form to the female of that species, figured in PI. XIX. fig. 1 . The general colour is reddish brown. The male has the head rather large and convex, of a bright orange colour. The eyes large and prominent. The antennae very long and slender, blackish, with three white annuli, the third being close to the tip. The pro- and mesothorax have the upper surface finely granulated ; the latter is rather widened in its hind part. The tegmina are rather broad, sub- quadrate ; the carina strongly marked, acute along its ridge, and elevated between the middle and base into a conical lobe rounded at its top ; the base of the tegmina is occu- pied by a broad entire yellow fascia. The wings are large, pale brown, with the base and apex uniform brown, the middle portion occupied with numerous slender white trans- verse reticulations ; the costal area is pale reddish brown, scarcely darker than the posterior area, and with the veins scarcely distinct ; the median one simple. The abdomen is long and slender ; the apical segments short and simple ; the anal styles produced into a pair of small curved forci- pated appendages, setose, incurved, and thickened at the tips. The terminal ventral segments are short and consi- derably swollen. The legs are very slender and simple, and of an orange colour. The female agrees with the male in general colours, but has the body more robust and the legs shorter ; the me- dian vein of the costal area is furcate at about 7\ lines from the base ; and the operculum is acutely boat-shaped, and extends to the extremity of the abdomen.

The pale- ringed antenna? and the elegant contrast of the two portions of the beautifully tinted wings distinguish this species. The general colour is dull luteous, tinged with green on the thorax, and with fulvous on the abdo- men, which is glossy. The head is broad, with the eyes very prominent, convex above, fine green, with a large yel- low rounded spot between the eyes. The antennae are very long and slender, blackish, with about five whitish annuli. The metathorax is finely granulated. The tegmina are small, subovate, rather strongly angulated near the middle ; the base, and a spot between the base and the middle of the inner margin, together with another spot beyond the middle of the outer margin, pale. The wings are rosy pink ; the costal area green, yellower at the base, with the veins darker green, the principal vein not being furcate. The abdomen is loug and slender ; the terminal segments con- siderably swollen ; the ninth dorsal segment with an acute 150 CATALOGUE OF ORTHOPTEROUS INSECTS. edge ; the anal styles obtuse, incurved, and forcipated. The legs are long, slender, unarmed, testaceous-coloured ; the basal joint of the tarsi as long as all the remaining joints united. The female is larger and broader, with shorter legs. The general colour resembles that of the male ; the pale spot across the middle of the tegmina transverse, and extending to the inner margin, and the pale spot of the outer margin more oblique. The chief vein of the costal area is furcate. The three terminal segments of the abdomen compressed and short ; the ovipositor not swollen, extending to the ex- tremity of the ninth dorsal segment ; the anal styles straight and obliquely porrected. The colour and form of the spots on the head and teg- mina vary in different specimens. In some males the head is spotless, in others it has a large rich fulvous-yellow round spot between the eyes. In some specimens of both sexes the spots of the tegmina are transverse, oblique, and whitish ; in others fulvous yellow ; whilst in some the spots are round and fulvous yellow. I at first considered the specimens with rounded spots on the tegmina as a distinct species, to which I gave the name of Ph. Eurybates, which they may retain, if ultimately proved to be a distinct species. Plate XIX. Fig. 7. The male, of the natural size. 7 a. The terminal segments of the body seen sideways. Plate XIX.

The head is small and convex, destitute of ocelli, fulvous, with a black spot on each side behind the eyes. The antennae arc black, with the two basal joints luteous green. The extremities are broken off at nearly an inch from the base. The prothorax is nearly equal in size to the head ; it is green, with the anterior lateral angles, two contiguous spots in the middle of the fore margin, a spot on each side above the insertion of the fore legs, and a spot on the middle of the hind margin black. The meso- thorax is short and rather narrowed in front, having a slight constriction close to the fore margin ; it is slightly rugose, green, with two spots on the disc towards the fore margin, a slender lateral line on each side, and a transverse spot near the hind margin black. The tegmina are broad, nearly square, with the angles rounded off, green, rugose, with a strongly angulated red carina. The wings are very large ; the costal area green in front ; the strong midrib red, furcate beyond the middle ; the hind part black, with the numerous transverse veinlets green ; membranous area brownish black, with a large basal spot and a subapical row of oval spots white. The abdomen is long and slender, chestnut-brown, with the junction of the segments, as well as the sides of the terminal segments, yellow. The legs are rather short and simple ; the tarsi with the basal joint as long as the three following taken together. Body be- neath luteous ; the three terminal ventral segments reach- ing to the extremity of the eighth dorsal segment, not swollen ; the articulations indistinct *, two curved thin appendages extending beyond the tip ; the anal styles of moderate size, extending beyond the extremity of the body.

Distinguished by its long and narrow form, destitute of spines, with the legs rather short and simple, and the wings large and reticulated. General colour reddish buff. The head with a slender black line down the middle, and one on each side behind the eyes. The antennae long and slender, especially beyond the middle, with very numerous short joints ; they, as well as the legs and anterior part of the body, are finely villose. The pro- and mesothorax have a fine black line down the centre, and the latter has also a fine line on each side within the lateral margin of the mesonotum. The tegmina are small and shortly ovate, strongly carinated down the middle, which is elevated into an angle a little before the centre of the carina. The wings are large and rather hyaline, with the longitudinal veins brown ; all the transverse veins widely bordered with a brown shade, which becomes confluent towards the tips of the wings ; the costal area fulvous buff, rather darker at the base in the female, and slightly clouded with darker shades. The legs are rather short and simple, and marked with several very fine dark longitudinal lines ; the tarsi have the basal joint as long as the three following. The abdomen is reddish brown, with several fine dark longitu- dinal lines ; that of the male is narrow and of nearly uni- form width ; the seventh joint rather narrowed ; the ninth wider, with the posterior lateral angles rounded off; the terminal ventral segments are scarcely swollen, the eighth and ninth being confluent and pointed at the tip, which does not extend beyond the eighth dorsal segment ; the anal styles are prominent, slender, and obtuse at the tips. The female has the extremity of the body gradually attenuated, the terminal joint being bifid at the tip, with the anal styles protruded backwards and placed close together, giving the appearance of an extra minute joint. The operculum is but moderately swollen, and extends to the middle of the ninth dorsal segment, its apex being bifid. 154 CATALOGUE OF ORTHOPTEROUS INSECTS. Plate IX. Fig. 6.

I have only seen a single male of this pretty species, the general colour of which is pale obscure greenish lutescent ; it is smooth and destitute of spines or tubercles, except two small conical tubercles on the mesonotum rather beyond the middle. The head is considerably wider than the prothorax, with the eyes very prominent ; the hind part of the crown is somewhat conically elevated. The antennae are long, very slender, and with the joints scarcely distinguishable. The mesonotum has a fine central longitudinal carina, and on each side below the raised lateral margin is a short red line running to the base of the tegmina. The tegmiua are small, short, subovate, rather sharply carinated down the middle, and with the centre angulated ; they are brown, with the veins pale, and forming a strongly reticulated surface. The wings are large, pale brown, the extreme base of a delicate green colour, and the apex pale along the margin ; the transverse veins are rather widely stained with rather darker brown ; the costal area is dirty luteous, with the longitu- dinal veins greenish, the principal vein not being furcate. The abdomen is long, filiform, smooth, and of a red co- lour, knobbed at the extremity ; the three apical ventral segments being considerably swollen, and extending nearly to the extremity of the ninth dorsal segment ; the anal styles are short, broad, curved, and somewhat forcipate. The legs are of moderate length, slender, simple, and of a greenish lutescent colour ; the basal joint of the tarsi about as long as the three succeeding joints. Plate XVI. Fig. 2.

W.W. Saun- ders. Of this pretty little species I have only seen a single male, of which the hind legs were wanting. It is smooth, and destitute of spines or tubercles. The head, pro- and mesothorax, tegmina, and costal area of the wings are green ; the mesothorax obscure greenish brown ; the abdo- men red ; the legs obscure reddish, with the tarsi pale buff. The head is larger than the prothorax, very convex, and elevated at the hind margin, glossy, with the eyes very prominent, and having a yellow longitudinal line on each side behind the eye. The antennae are long and slender, brownish, paler at the base. The prothorax is small, glossy, with two yellow spots in front and a larger broader one behind. The mesothorax is not half as long again as the prothorax ; it is narrowed towards the base, which is ornamented above with a yellow spot, and the hinder part with a yellow line on each side. The tegmina are small, nearly oval, strongly angulated above in the middle near the base, green, with a pale line on the outside of the an- gulated ridge. The wings large, brown; the costal area green, with a pale longitudinal line ; the fore margin dusky ; the chief vein is simple. The abdomen is long, subclavate, brownish red ; the eighth dorsal segment much larger than the ninth, which is small and semiovate ; the anal styles large, exserted, and thickened at the tips ; the three termi- nal ventral segments are moderately swollen, the ninth not extending to the extremity of the eighth dorsal segment. The legs are simple, slender, and of moderate length (the hind ones wanting) ; the femora and tibiae obscure on the outside, dull reddish on the inside; the tibiae dark at the tips, and the tarsi pale buff.

This very remarkable species is well distinguished by its straight anterior femora, its short square spotted tegmina, and its large multivenose wings with the pale brown costal area spotted with black. The head of the female is mo- derately large, rather convex, with three slender dark lines on the hind part of the crown. The antennae are slender ; but the tips in the unique female which I have seen are broken off. The prothorax has its anterior lateral angles truncated and incised ; its slender hind margin is bright scarlet. The mesothorax is not more than one and a half times the length of the prothorax ; it is slender in front, two-thirds of its hinder portion being widened, its disc gra- nulose, and the anterior portion of the dilated part with two large rounded tubercles. The tegmina are short, sub- quadrate, brown, each with about six small black spots ; the tubercle of the carina is very prominently elevated and obtuse. The wings are very large, pale smoky-coloured, the membranous portion very thickly and transversely veined ; the costal area is fulvous brown, the second vein furcate, each of the longitudinal veins bearing a series of small round black spots. The abdomen is rather wide ; the two terminal segments small, the last entire ; the caudal styles rather short and obtuse. The operculum extends nearly to the extremity of the body ; its tip is emarginate ; the sixth ventral segment is entire along its hind margin. The legs are short, rather robust, and unarmed ; the anterior femora are straight, being in nowise emarginate at the base ; the basal joint of the tarsi is about as long as the three following joints united.

The insect which I consider to be the male of this spe- cies is contained in the Collection of Mr. Westermann of Copenhagen, and is represented in PL XXXV. fig. 5. It is of an obscure luteo-fulvous colour ; the mesothorax with a green fascia in front ; the tegmina and costal area of the wings marked with numerous small round greenish-black dots ; the membranous portion nearly pellucid, and scarcely tinged with brown ; the veins very slender, but distinct ; the median vein of the costal area is simple, but it is united with the next at a short distance from the tip of the wing ; the antennae are slightly annulated with whitish. Plate XXXV. Fig. 5. The male, of the natural size. 5 a. The terminal segments of the body seen sideways. A variety of the male of this species has been sent from Sarawak by Mr. Wallace. It is represented in PL XXXV. fig. 4, and is slender and of a fulvous-brown colour ; the head very convex ; eyes very prominent ; antennae very long and slender, brown, not annulated with white, the base luteous ; the pro- and mesothorax granulated, the latter twice the length of the former, with two-thirds of its hind portion elevated, the anterior part of the elevated portion slightly bituberculated. The membrane connect- ing the head and prothorax and the pro- and mesothorax is bright scarlet ; the mesothorax is also distinguished by a narrow green margin in front. The tegmina are nearly square, strongly carinated, reddish brown, with the veins slender and pale fulvous, forming reticulations. The wings are uniform smoky brown ; the costal area fulvous brown, with the transverse veins slender, placed very regu- larly at short equal distances apart, and pale luteous ; the median vein simple. The abdomen is brown ; the extre- mity much swollen beneath, paler luteous. The fore legs are wanting in the only specimen I have seen ; the middle and hind ones slender, sanguineous, with the articulation between the femora and tibiae pale buff.

This species is at once distinguished by its short bi- tuberculated mesonotum, and short broad tcgmina very strongly elevated between the base and middle, and the numerous minute spines on the front parts of the body. The head is rounded, very gibbose ; eyes very prominent ; hinder part of the crown armed with several rows of mi- nute spines. The antenna; are short ; the joints slender, short, and very numerous ; they are dark brown, annulated with buff, the anuuli being near together towards the base. The pronotum has the anterior lateral angles acute and porrected, and the disc is furnished with a few acute gra- nules. The mesothorax is not twice the length of the pro- thorax ; it is widened behind, especially in the female, and is furnished with numerous small tubercular spines, the disc being armed with two elevated granulose tubercles a little in advance of the middle. In the male the mesothorax is comparatively more elongated than in the female. The metathorax is longer than the mesothorax (being nearly double its length in the female). The tegmina are nearly square, with the angles rounded (those of the male being rather longer than those of the female) ; the elevation of the carina is very strongly raised and rounded, especially in the female ; the veins are pale buff and finely reticulated. The wings are large and brown, with the longitudinal veins rather darker ; the costal area is mottled with black, green, and obscure buff; the chief longitudinal vein is simple in the male, but furcate in the female. The legs are short (comparatively longer in the male), slender, and simple ; the anterior femora very slightly sinuated at the base. The abdomen of the male is slender, linear, and clavate at the extremity, the eighth segment being much the widest, and the ninth short and nearly straight at its extremity, with the sides rounded off ; the anal styles are rather thick, por- rected, curved, and obtuse at the tips ; the three terminal ventral segments are considerably swollen, and scarcely ex- tend beyond the base of the ninth dorsal segment. The abdomen of the female is gradually narrowed ; the three terminal dorsal segments carinated ; the ovipositor is scarcely swollen, and extends to about the middle of the ninth dorsal segment.

The female of this beautiful species is unique in the Col- lection of Mr. Westermann of Copenhagen, a gentleman who possesses one of the most beautiful collections of in- sects in existence, a large portion of which was collected by himself in Asia and Africa. It is closely allied to the female of N. Medora (PI. XXVII. fig. 1), but differs in the smooth anterior portions of the body, short legs, and tessellated wings. The body is comparatively robust, espe- cially in the region of the metathorax ; it is smooth, green, and opake. The head obovate ; eyes very prominent; ocelli obsolete. Antenuse very slender, of moderate length, and brown ; hind part of head very convex, unarmed, the fore part luteo-fuscous. The prothorax is short. The meso- thorax subcorneal ; it is swollen above in the middle into two raised lobes terminating in points ; it and the prothorax are obscure green, with a slender transverse sanguineous mem- brane in front of each. The tegmina are broad, flat, with 158 CATALOGUE OF ORTHOPTEROUS INSECTS. the carina strongly raised towards the hase, forming a large obtuse lobe ; the reticulation is indistinct. The wings are large and brown, with very numerous, narrow, transverse, irregular, white undulating fasciae, most distinct towards the anal margin ; the apex of the wing and the portion of membrane between the two areas white ; costal area green, with the base darker ; the median vein furcate. The meta- notum and abdomeu are black ; the latter with wide lu- teous fasciae occupying the bases of the segments ; the two terminal segments are very convex ; the operculum scarcely swollen, extending to about the middle of the ninth dorsal segment ; anal styles porrected and obtuse. The under side of the body and legs are luteo-fuscous ; the latter are setose and simple, short and slender, with the basal joint of the tarsi short. Plate XXXVIII. Fig. 3.

Abdomen elongated, flattened ; anal styles abbreviated. Inhabit South America. These insects are distinguished from most of the pre- ceding by the more elongated tegmina, which are, however, much shorter than in some of the subsequent genera ; hence the name here proposed for the present group. They are united by Burmeister and De Haan with Bin- elytron, to which they are perhaps too closely allied. The three insects placed by Serville in his genus Platycrana belong to three separate groups, whilst his first section of Phasma comprises the species of Platycrania which bears his name. If Cayenne, and not Amboyna, be the real country of Ph. acanthopterum of Stoll, it ought to find a place in the present group. The genus, as proposed by Mr. G. R. Gray, comprises PIIASMIDjE. metriotes. 159 several distinct groups ; and it is here confined to the spe- cies placed by him at the end of the genus and their allies. 1. (416.) Metriotes Stollii.

I have seen but a single specimen of the female of this species, and am therefore unable to determine whether the peculiar circumstance of the head being armed on the right side of the crown with a single spine be a permanent spe- cific character or not. The general colour is of a reddish or fulvous brown, opake, and with the head, pro- and me- sothorax very slightly rugose. The head is oblong, con- vex, marked on the crown with several dusky lines, and armed also on the right side of the centre with a small erect spine. The antennae are long, and slightly thickened towards the base. The pro- and mesothorax are convex and unarmed, the latter scarcely twice the length of the former. The tegmina are oval, with the central carina well defined towards the base, and armed with a small acute erect spine. The wings are of moderate width, very pale brown with a reddish tinge ; the costa pale brown, with the chief vein furcate. The legs short and simple ; the fore femora dilated ; the anterior tarsi with the basal joint as long as the three following united. The abdomen is convex ; the three terminal segments narrowed and short- ened, the last rounded at the tip, with the anal styles ex- posed at the extremity. The operculum is short aud flat, extending to about the middle of the eighth dorsal segment, the inner appendages forming two rows of flattened plates. Plate XV. Fig. 7.

The head, pro- and mesothorax are dirty luteous, with several dusky lines, marked, especially on the head, with minute tubercles. The prothorax and mesothorax are flat- tened above and granulose, with the lateral angles acutely deflexed. The tegmina are oval, about as long as the head, pro- and mesothorax united j they are dirty luteous-coloured, with an ill-defined darker streak down the middle, the central ridge being but slightly indicated. The wings are large ; the costal area obscurely coloured with dirty luteous and darker brown cloudings ; the main vein is furcate at a short distance from the base ; the posterior area of the wings is pellucid, with a small pale blue spot at the base, followed by a large dark brown patch, shaded gradually off behind ; all the transverse veinlets of the wings clouded with brown. The legs are rather short, simple, and finely hirsute ; the anterior femora subcompressed ; the tarsi short, with the basal joint about as long as the second and third united. The male is much narrower than the female, with the legs more slender, and generally of a paler luteous tint. The fifth, sixth and seventh segments of the abdomen are gra- dually widened ; the eighth short, gradually narrowed, with the posterior margin deeply and acutely emarginate in the middle ; and the ninth segment is very small and deeply notched, with the two anal styles porrected, curved, form- ing a small forcipated appendage ; the three terminal seg- ments beneath are nearly flat, and the last is rounded at its extremity. The abdomen of the female is gradually attenuated, with the terminal segments carinated and of nearly equal length, the last being bi-emarginate behind, ex- posing the porrected anal styles ; the oviduct is very short, scarcely extending beyond the seventh dorsal segment, the interior appendages forming a double series of flattened plates.

I am indebted to Mr. Curtis (in whose collection the typical specimen described by Mr. G. R. Gray is still con- tained) for an opportunity afforded to Mr. Haliday for making a sketch of this species. The type is a male, of which the extremity of the abdomen is mutilated. Having also examined and drawn the typical specimens of Ph. lichenale of Burmeister, in the Berlin Museum, I have scarcely any doubt of their identity with Mr. Curtis's in- sect. The following are Burmeister's characters of his Ph. lichenale : — " Viridi-cinereum ; antennis annulatis, alarum area an- tica roseo fasciata, postica venis transversis nebulosis ; ely- tris tuberculo medio rugoso ; dehinc fascia rosea.

The insects of this group are certainly very closely allied to those of Metriotes, with which they were united by Bur- meister and De Haan.

This pretty species is long and rather slender (especially the male), and is well distinguished by its peculiar colours and comparatively short mesothorax. The head is large, rounded, and very convex behind, with two small im- pressed lines between the eyes in front, and with traces of longitudinal pale lines in the hinder part ; ocelli wanting. The antennae are long and slender. The prothorax is square, with the anterior and lateral margins elevated. The mesothorax is short, being about one and a half times the length of the prothorax ; its disc is granulose, the granules pale, a central line and the lateral margins slightly elevated. The tegmina are elongate-ovate, rather more than half the length of the wings, with a small raised tubercle near the base ; they are pale green. The wings are large, opake white, with luteous longitudinal veins and a broad black apical margin ; the costal area is pale along its basal half, the remainder being greenish brown ; the chief vein is fur- cate near the base in both sexes. The abdomen is long and dark brown, slender in the male, with the tip recurved ; the three terminal joints rather dilated at the sides above and carinated along the middle ; the terminal ventral seg- ments are dilated, gaping at the extremity, exposing a pair of horny hooks and the short anal styles ; the three ter- minal segments of the female are short and narrow, with the anal styles exserted ; the operculum short, exposing at its extremity a flattened internal plate, which reaches to the tip of the abdomen. The legs are short and robust, especially the hinder femora ; the anterior femora are but slightly twisted at the base ; the hind femora are dusky at the tips, and these, as well as the hind tibiae, are finely ser- rated beneath ; the tarsi have the basal joint rather longer than the three following joints united.

In Brasilia apud Villain Novam (D. Bates). B.M. I am only acquainted with the male of this curious and very slender species, which ill agrees with the preceding in- sects, and seems to approach the Prisopi. Its general co- lour is pale greyish brown, opake, with the head, pro- and mesothorax, and hinder part of the abdomen granulated. The head is short and rounded in front, convex, with two rows of short obtuse points on the hinder part of the crown, four in each row, the outer pair in the anterior row being the largest. The antennas are rather short, 23-joiuted, the third and three or four following joints very short, the re- mainder gradually lengthened. The pro- and mesothorax are of equal width, the latter about twice the length of the former; the metathorax shorter than the latter, its two divi- sions of equal length. The tegmina are oval, obscure light brown; the outer half of the anterior margin pale green ; the median carina considerably arched towards the base. The wings are opake, brownish white, with a dark shade along the outer margin, the veins strongly marked and dark brown ; the costal area pale brown, bright pink for about one-third of the length from the base ; the chief vein is simple. The abdomen is long, cylindrical, simple, and narrower than the thorax, smooth at the base, slightly ru- gose beyond the middle ; the three terminal joints dilated, the last truncate at the tips, with the sides oblique and emarginate, and the anal styles slightly produced ; the ter- minal ventral segments are considerably swollen (the extre- mity is injured). The legs are short ; the anterior femora curved, rather wide, and slightly waved along the hinder edge ; the anterior tibise short, gradually narrowed to the tip, with a small hind lobe at the base ; the four hind fe- mora are short, thick, with three strong teeth on the under edges, slightly angulated near the extremity of the upper edge ; the tibiae rather slender and slightly bilobed ; tarsi short, with the basal joint not longer than the second and third united. The metasternum is considerably dilated at the sides, with two deep punctures in the middle. Plate XXI. Fig. 6. The male, of the natural size. 6 a.

I have only seen a single specimen of the male of this species (which also differs considerably from the types of this group, and which, when the other sex is- known, will probably be found to constitute a distinct genus), in the National Collection. It is of a dull luteous-brown colour, and opake with a greenish tinge, the head, pro- and mesotho- rax being finely granulose. The tegmina are dark green in the middle, the sides being of a browner tint, with a pale straw-coloured oblique vitta arising on the outside of each near the base and extending to the middle ; the hind wings have the costal area pale greenish brown, with darker veins and veinlets, and the hinder area is very slightly tinged with dusky, with thick longitudinal blackish veins and dusky transverse ones. The head is broader than long, flattened between the eyes ; the flattened part bordered by a semicircular row of about eight small conical points, the two central ones being the largest. The antennae are thick and hirsute (the tips broken off in the specimen before me). The pronotum has two small erect spines in the middle of the hind part of its anterior division, the posterior division having also a pair of stronger laterally porrected spines near the hinder angles ; the deflexed margins of the mesothorax are sinuated. The tegmina are about the length of the pro- and mesothorax united, elongate-ovate, narrowed be- hind. The wings moderately large. The abdomen is much narrower than the thorax, with a raised central line run- ning down the middle ; the fourth and following segments also with a similar raised line on each side ; the seventh segment is gradually widened behind, the eighth long and gradually narrowed, the ninth small and subquadrate ; the anal styles small ; the eighth segment is furnished beneath with a broad foliaceous lobe extending considerably beyond the extremity of the body ; the seventh ventral segment and the base of the ninth are moderately and roundly- swollen, the last extending nearly to the extremity of the ninth dorsal segment. The legs are short and rugose ; the femora dilated, especially the anterior pair, which are ful- vous, with a broad black longitudinal mark beneath ; the under edge of the four posterior with several short spines ; the tarsi have the basal joint scarcely longer than the se- cond joint. The prosternum has two minute setose lobes behind the base of the fore legs. Plate XIII. Fig. 5. The male, of the natural size. 5 a. The three terminal segments seen laterally. 5 b.

Body large, with elongate-ovate tegmina and very large wings in both sexes. Head oblong, destitute of ocelli ; of the female flat, posteriorly subconvex. Antennae of the male as long as the entire thorax, 24-jointed ; of the female scarcely longer than the mesothorax, 26-jointed. Meso- thorax of the male slender, cylindrical, twice the length of the prothorax, sides finely serrated ; of the female about twice the length of the prothorax, subtriangular, carinated in the middle, with the sides slanting and serrated. Teg- mina of the male extending nearly to the middle of the first segment of the abdomen ; of the female about half the length of the abdomen ; median carina scarcely elevated iu both sexes. Wings in both sexes large, nearly as long as the abdomen ; those of the male narrower. Legs short, simple ; basal joint of all the tarsi short ; four posterior femora in the male slender and strongly serrated on all their angles, those of the female with the fore margin di- lated and dentated. Abdomen of the male long, slender, and cylindric ; of the female broad, gradually narrowed to the tip, sides margined ; ovipositor large, boat-shaped, ex- tending beyond the extremity of the abdomen, but shorter than the anal styles, terminated in both sexes by mode- rately long anal styles. 1.

Without any positive statement of the fact to rely upon, I believe there can be no doubt that the Diura Typhosus of G. R. Gray (which De Haan, Orth. Orient, p. 128, has, as it appears to me, improperly regarded as the male of Cypho- crania Goliath) is the legitimate partner of Tropidoderus Childrenii. The amount of development of the wings seems to be subject to some variation in this species, as Mr. Fortnum brought from Adelaide specimens of the female measuring 5^ inches in the length of the body, with the wings expanding fully 9 inches, and with the tegmina broader than in the type figured by Mr. G. R. Gray. I cannot, however, discover any real specific character be- tween these different specimens. It is true, that those from Adelaide have the basal portion of the costal area of the wings of a beautiful rose-colour ; the under surface also of the whole of the costal area is of the same colour, with the longitudinal veins pale yellow, and the tegmina also tinged with rosy; whilst another specimen of the female, measuring 5 inches long, with the wings only expanding 6^ inches, has the basal portion of the costal area half rosy and half pale yellow. 2.

Prisopus, Servi/le, Ene. Meth. t. x. Burmeister ; De Ilaan. Prisopus et Platytelus, G. R. Gray. Body of the male somewhat linear, of the female broad and subdepressed ; terminal segments of the body gene- rally furnished with membranous lobes at the sides ; anal styles moderately long. Head subquadrate and subde- pressed ; ocelli wanting. Antennae long, pubescent, multi- articulate. Prothorax and mesothorax of nearly equal length. Tegmina elongate-ovate, generally about two- thirds of the length of the wings. Wings very broad and rounded, generally not quite covering the extremity of the abdomen. Legs, especially the anterior and posterior pairs, with dilated membranous sinuated lobes on the femora, the margins of which are strongly ciliated ; tibife dilated, the anterior pair with two small membranous detached lobes at the base ; basal joint of the tarsi of moderate length. Abdomen of the females with the ovipositor flattened, and not extending beyond its extremity. The general habitat of these curious insects appears to be South America, although Amboyna was given as that of the typical species by its first describers. Whether the "habitat in Indiis," given by Lichtenstein to Ph. Ohrt- manni, be intended for India, appears to me very doubtful. Two pupse are, however, figured by Stoll, one of which is stated to be from Samarang, Java, and the other from India. Some credibility seems to be given to these locali- ties by that of the Cape of Good Hope given by De Haan to Ph. Horstokkii (which may possibly be doubtful), and also possibly by that of the Isle de France given as the country where the unique specimen of Pr. Marchali (Xe- roderusl Marchali, ante, p. 103) was taken by M. Marchal himself, who resided in that island. Hitherto the characters of the genus have been derived from females alone, no specimen of the opposite sex having hitherto been described by any previous author : Burmeister indeed considered the genus Xerosoma as the males. The males of several species are described below. 1. (437.) Prisopus flabelliformis.

The locality of Amboyna given to this species by Stoll, together with the circumstance that the membranous lobes of the terminal segments of the abdomen in the specimen of the female figured by that author were incurved beneath the body, as is often the case, and consequently not re- presented in his figure, led Burmeister to consider Stoll's insect as forming a distinct section in the genus, and con- sequently as distinct from the Brazilian insects which he had before him. This circumstance he corrected in his memoir in Germar's Zeitschrift, where, however, he con- siders his Prisopus spiniceps as identical with Stoll's insect, retaining Pr. sinnicollis as distinct. I am unable to sepa- rate the last-named species from Stoll's figure, believing that the want of a pair of spines on the pronotum in that figure is an error of the artist. On the contrary, Bur- meister's short description of Prisopus spinicollis is as follows : — " Cinereo-viridis ; spinis verticis minoribus simplici serie ; pronoto scabro, bispinato ; alarum area postica albida ; venis transversis nigris. — Long. corp. unc. 2£. — Habitat in Brasilia*." Bunneister's description of Pr. spiniceps accords better with Serville's description of the insect, which the latter regarded as the Pr. flabelliformis, but which seems to me to differ from Stoll's figure, judging as I do from a speci- men evidently named by Serville himself, formerly in M. Marchal's collection, now preserved in the Hopeian Mu- seum. This wants the two spines on the pronotum, which, on the contrary, is granulated, as well as the mesonotum ; * The reference by Burmeister of this species to Xerosoma canali- culatum, and by Dc Haan to Plalytelus horridus of G. R. Gray, cannot be adopted. and the wings have the posterior area black, the spaces be- tween the broadly-stained transverse veins being very small, and stained with light brown, and not greenish white and distinct as in the other species. The male of this species, which appears to be extremely rare, not having been seen by any previous writer, has long been in my Collection. It agrees in general characters with the female, except in being smaller and much more slender, the basal segments of the abdomen not being more than 2 lines broad, which is indeed the general width of the insect. 2.

Referring to the observations on the preceding species, I shall here merely add, that the specimen of the female in the Hopeian Collection, which agrees with Burmeister' s characters, but which bears Serville's label Pr. flabelli- formis, has the following proportions : — Long. corp. unc. 3i ; cap. lin. 4 ; proth. lin. 3£ ; mesoth. lin. 5 ; metath. lin. 7 ; abdom. lin. 18 + liu. 4 = lin. 22 ; tegm. lin. 17 ; alar, expans. unc.

The spines at the back of the head are not larger than those in Pr. flabelliformis ; the surface of the head is nearly smooth ; the pronotum and mesonotum are distinctly granulated ; the costal area of the wings is more tessellated in the middle, the hinder area very much darker, and the ventral segments of the abdomen are marked on each side with a triangular dark patch united in the middle, but not forming distinct fasciae. 3.

The general appearance of the unique female hitherto known of this species, formerly in my Collection, is so similar to that of Phasma Horstokkii of De Haan, that, were it not for the difference of locality, I should be tempted to consider them as varieties of the same species. The suggestion of De Haan, that it is possibly identical with Pr. spinieollis, is destitute of foundation. I can find no generic characters to separate this species from the typical Prisopi. 5.

The head, pro- and mesothorax, and extremity of the abdomen thickly covered with small granules of a whitish colour ; the hind part of the head also with larger tubercles, of which the hinder form an irregular transverse series rather larger than the rest. The antennae are setose, rather thick, with the fourth and following joints short, but gradually lengthening ; in the male they are 25-jointed. The pro- and mesothorax are nearly of equal size and ap- pearance, being rugose ; the former is spiraculiferous at its fore angles, the sides being rather dilated in the middle. The metathorax is as long as the pro- and mesothorax united, its hinder division being nearly twice as long as the fore part. The abdomen is narrow and parallel in the male, but broader and gradually widening to the sixth seg- ment in the female, the sides being strongly deflexed ; the fifth and following segments produced at their posterior lateral angles into a rounded, setose, deflexed lobe ; the ter- minal ventral segments in both sexes are flat, and the anal styles are long and flattened. The metasternum is marked on each side with a black spot, and the ventral segments of the abdomen are fasciated with black. The tegmina are about two-thirds of the length of the wings, brown or greyish, varied with darker shades, the colour of the veins being more or less interrupted ; the main vein is elevated near the base into a small tubercle. The wings are large, opake whitish, with the transverse veins very broadly stained with brown ; the costal area is strongly shaded with pink throughout its greater portion, varied with brown patches with paler round spots ; the apex is more uniformly PIIASMID.E. PRISOPUS. 169 brown ; the principal vein is simple, except towards the apex, where it emits two or three branches running to the fore margin. The legs are broad and hairy, rather short, especially in the female ; the fore femora are strongly arched, the outer edge scolloped ; the tibice with two lobes at the base ; the four hind femora and tibiae are scolloped along the lower margin, as also more slightly so on the fore or upper margin.

The head is comparatively broader and flattened, with two small tubercles behind the eyes, and a row of six similar ones across the hind part of the head. The antennae are27-joiuted. The pro- and mesonotum are armed with a few small tubercles. The abdomen is elon- gated, with the 6th, 7th and 8th segments produced on each side into an elongated lobe rounded at the extremity and deflexed ; the anal styles are of moderate length and flattened. The tegmina and wings are coloured as in Pr. Berosus, except that the costal area is destitute of the pink tint. The legs are also similarly formed to those of that species, except that the hind ones are rather longer and the tarsi are more slender. The metasternum is entirely luteous brown ; but the abdominal segments are fasciated with black. These differences seem to me sufficient, in conjunction with the locality of the specimen described above, to war- rant its being considered as specifically distinct from Pr. Berosus of Western North America. 8. (444.) Prisopus incertus. Pupa. Brunnea ; thorace albo maculato ; pedibus om- nibus membranaceis, ciliatis, nigro annulatis. Long. corp. 2" 3'" ; anten. 2" 2"'.

This species is of a dull pale luteous coloui , varied, espe- cially on the legs, with brown shades. The head, pro- and mesonotum are covered with numerous gran ules and small conical tubercles ; the head is nearly square. The antennae slender and few-jointed. The mesothorax is short, and gradually widened from the front to the hind part ; and the abdomen is gradually narrowed from the base to the apex in the male, but widened in the middle in the female ; in the former sex the segments are also slightly lobed at the extremity of each, and they are marked with longitudinal posteriorly diverging carinae down the centre. The tegmina are oval, with the central carina scarcely elevated into an angle towards the base ; they are grey-coloured, varied with white spots. The wings are dull opake buff-coloured, varied with irregular brownish fasciae ; the costal area is pinkish grey, brighter-coloured at the base, and varied with brown markings ; the main vein is furcate at about one-third of the length of the wing from the base. The legs are mode- rately long ; the fore femora arched and strongly serrated on each angle, the serratures clothed with curved hairs ; the fore tibiae are slender and but slightly lobed, but the four posterior tibiae are lobed, especially on the upper edge, and subserrated. The female has the oviduct wide at the base and truncate at the extremity, which does not extend beyond the eighth dorsal segment ; it is flattened, and followed by a furcate appendage, the divisions of which are obtuse ; the anal styles are minute and lateral. I am indebted to M. Guerin-Meneville of Paris for a knowledge of this remarkable species. Plate XXI. Fig. 1. The male, of the natural size. 1 a. The extremity of the body seen sideways. 1 b.

The former of these names, according to the ordinary rule of retaining that given to the male, would have been adopted if Mr. MacLeay's name had not the priority, and were equally applicable to both sexes. The specimen figured by Gray as a male pupa is an immature female, and is pre- served in the Hopeian Museum. The curved black horny appendage at the extremity of the body appears to me to be a mass of excrement emitted by the insect. Genus 39. PHYLLIUM.

Mesothorax very short, with the sides dilated and spined. Tegmina of the male rather longer than the metathorax ; of the female very large and foliaceous, nearly covering the abdomen. Wings of the male large, extending nearly to the extremity of the abdomen, semioval, of delicate texture ; costal arch distinct and broad, but not coriaceous ; wings of the female rudimental, or much shorter than the teg- mina. Legs short ; the femora, and often the tibiae, with broad membranous lobes. These insects recede so much further from the ordinary type of the family than any of the other species, that they have received the common name of Walking-leaves, whilst that of Walking-sticks is given to the more ordinary form. The former of these names is indeed very applicable, for both whilst alive and seated among the leaves of the trees on which they live, and also when dead and faded in colour, it is impossible to conceive a more exact representation of a growing or withered leaf. Indeed, Mr. Murray informs us, that it was only on pointing out the living specimen reared at Edinburgh, whilst resting quietly on the plant on which it subsisted, that many of the visitors were able to perceive it. I have represented at the foot of Plate XXXI. several specimens, illustrating the transformations of this genus. Fig. 4 represents a young larva of a species allied to Ph. crurifolium and Scythe (Ph.

As some confusion has arisen as to the real species de- scribed by Linnaeus, I have thought it useful to copy his original description from the ' Museum Ulrica? Reginae' : — " Caput ovatum, laeve ; antennae brevissimae, obtusae, ar- ticulis 9, quorum 1 bascos latior, 2 brevissimus, 3 major re- liquis, 4, 5, 6, 7 brevissimi lenticulares, 8, 9 ovati.

De Haan gives the following measurements of various individuals, all of which are females. From the relative length and width of some of the specimens, I should appre- hend that the whole of them could scarcely be referable to one species. a. Long. corp. 4" 2'" ; lat. corp. 1" 4^'". b.

De Haan has added the following description of a pupa, of which he has also given a figure (pi. 15. f. 7), which PHASMID,£. PHYLLIUM. 173 Mr. G. R. Gray has considered as move probably that of a different species (Ph. Geryoii) : — " Nympha maris antennis 3'" longis glabris crassis, latere interiore planis, extcriore rotundatis, ex 24 articulis com- positis ; alis usque ad marginem posteriorem articuli l mi abdominis productis ; vagina convexa, apice rotundata ; tibiis uti in characteribus specificis laudatis, femoribus an- ticis parte interiore tantum lobatis." I cannot bring myself to think that Perry's Mantis foli- utus, on which Mr. G. 11. Gray has founded his Ph. Gorgon, is anything else than an ill-drawn figure of a female of Ph. siceifolium, rather increased beyond the true size, and with the sides of the abdomen distorted and probably bent up- wards. RSsel's figure, referred to by Linnaeus, represents a female specimen, in which the four anterior legs have evidently been broken off and transposed, the middle pair as represented being evidently the fore legs. The insect represented as the male in the Crochard edition of the Regne Animal, Ins. pi. 79. f. 1 A, is a male pupa, with the antennae of the intermediate size between that of the larva and the perfect male. Most of the specimens of the female which I have seen are old ones, to which no precise locality is attached ; but in the Hopeian Collection there is one from the Collection of Latreille with the locality "Seychelles" attached to it in his handwriting. 2.

There is a specimen in the Collection of the Jardin des Plantes, which appears to agree with Stoll's figure above referred to ; but it is only 2| inches long ; the tegmina are long, extending to the extremity of the second segment of the abdomen, which latter is rounded at the sides, the widest part being at the extremity of the fourth segment ; the sides are, however, bent upwards. I was for some time deceived as to this specimen, in consequence of its having had a fore leg replaced by a hind one, and am still by no means satisfied that it is anything else than a discoloured and somewhat ill-dried specimen of the male of Ph. sicei- folium. 3.

In the Hopeian Museum is another female, from Manilla, in which the wings are still larger, reaching rather beyond the middle of the fifth segment of the abdomen.

I have only seen a single specimen of this very distinct species, in the Collection of the British Museum. It agrees with Ph. Celebicum in possessing moderately developed (although shorter) wings, but differs entirely from that species in the form of the femora and abdomen, and in the lobed condition of the posterior tibiae. In the shape of the abdomen it approaches Ph. Geryon, but differs from that species in the developed wings and in the lobed hind tibiae. Plate XXXI. Fig. 3. The female, of the natural size. 3 a.

In both the latter and the British Museum specimen the body may be said to form an elon- gated lozenge or diamond, the anterior point being placed at the front of the prothorax, and the widest part being near the end of the third segment of the abdomen. 6.

I feel satisfied, from an attentive examination of the de- velopment of the tegmina and wings in the two sexes of this genus, that Donovan's figure above referred to, not- withstanding the minute size (probably inaccurate) of the autennse, is intended for the pupa of a male insect, and not that of a female, as suggested by Mr. G. R. Gray. Without a more precise knowledge of its locality, it seems scarcely possible to identify it with the perfect insect, of which it is in so immature a condition. 12. (460.)

The Hopeian Museum possesses two of the supposed males of this species : one from the Collection of M. Mar- chal, named by Serville, with "Seychelles" indicated as the habitat, in the handwriting of Latreille ; and the other, which I obtained from the Collection of Serville itself. I can discover no difference between these two specimens and the typical specimen of the male of Phyllium, bioculatum, as represented from my drawing in Griffith' s Animal Kingdom, both exhibiting traces of the two spots on the inner mar- gin of the fore femora, notwithstanding Serville, in a note, implies the want of these two marks, and consequently thereupon maintains the distinction of the two species. It is proper to observe also, that the margin of the basal half of the outer lobe of the fore femora exhibits traces of the three minute denticles which exist in the same part of the male of Ph. bioculatum. The Hopeian Collection also possesses several females of this species, also labelled from the Seychelles and East Indies, from the Collections of Mar- chal and Serville, which agree with the description given by Serville. 13.

Ins. Seychelles. In Mus. Hopeiano Oxoniae (e Mus. Marchal). I am compelled to propose a new species for the male insect above described, on account of the structure of the antennae, the length of the wings, the form of the abdo- men, and the want of the ocelli on the fourth segment of that part of the body. I do not know whether we may not already possess the legitimate female. In the general form of the legs it agrees with the male of Ph. crurifolium and Ph. Scythe, and, as in those species, the fore femora exhibit traces of the two pale marginal spots. Plate XL. Fig. 5. The male, of the natural size. 14. (462.) Phyllium pulchrifolium.

Its proportions agree in all respects with those given above. The figures representing this species in PI. XXXI. have been drawn from a series of specimens preserved in spirits, in the Collection of \V. W. Saunders, Esq. It will be seen that in the more immature state the insect is destitute of the two ocelli-like marks on the fourth segment of the abdomen. A very interesting account of the habits, metamorphoses, a ad growth of a male specimen of this insect, reared in the Royal Botanic Garden of Edinburgh, has been pub- lished by Andrew Murray, Esq., in the ' Edinburgh New Philosophical Journal,' new series, January 1 856 ; and the curiosity of the public to see this interesting animal during the eighteen months of its existence in the active state in one of the hot-houses of that establishment was so great, that the Curator of the Gardens, to whose care and judi- cious management the prolonged life of the insect was en- tirely due, found it necessary, for the health of the creature itself, to forbid its being shown on more than four days in the week.

Having, however, subsequently examined the type-specimens of B. spatulata, described by Burmeister, in the Berlin Museum, I find the female identical with the Hopeian insect described by Gray, 2 a 2 180 CATALOGUE OF ORTHOPTEROUS INSECTS. and doubtfully considered by Burmeister as identical there- with.

The following is a detailed description of the female type, contained in the Hopeian Collection : — Body long and cylindrical, brownish green, rather shining ; meso- and metathorax and basal segments of the abdomen finely granulated, especially the former. Head oblong, simple. Antennae very long and slender, with very long joints ; the hind margin of the metathorax and of the two basal segments of the abdomen with a small raised tubercle in the middle, the fifth segment with a larger tubercle in the same situation, the eighth with the middle of its hind margin raised into an obtuse conical point ; the operculum extending far beyond the extremity of the abdomen. The fore legs are moderately long and simple ; the middle and posterior are shorter and stronger ; their femora with two foliated lobes near the base on the under side, and two similar ones on the upper side near the tips. The four posterior tibiae have the apex triangularly dilated. The Berlin specimen of the female has the upper surface of the body rather more strongly granulated, and the five basal segments of the abdomen have the raised tubercle in the middle of the hind margin. The following are the dimen- sions of the Hopeian specimen of the female : — Long. corp. fcem. cum operc. unc. 5g ; cap. tin. 3^ ; anten. unc. 2| ; proth. lin. 3; mesoth. lin. 13y; metath. lin. 9£ ; abdom. lin. 22+ lin. 6 + operc. ultra apicem ab- dom. extenso, lin. 8=lin. 36.

Phasma acicularis, Stoll (Phasma, pi. 25. f. 97), referred to Mantis by Mr. G. R. Gray (Syn. Phasm. p. 44), appears to me to be a specimen of a Ranatra deprived of its tails. P.S. — Mr. Bates has just forwarded to England a remarkable species, of which the following are the characters : — P. Ki4.— Sp. 4*. (471.) Dinelytron Batesianum, TFeshv. Elongatum, cylindricum, htve ; capitis viridis vcrtice eonieo, elcvato, bispinoso ; prothorace nigricante ; mesothorace brevis- simo, albo ; metathorace abdoraineque piceis ; tegrainibus nigris macula maxima costali alba; alis nigris macula magua basali triangulari alba ; pedibus obscure viridibus (fcem.).

In Brasilia, ad fluv. Amaz. super. (D. Bates). Closely allied to D. Zymbraus. Head green, larze, hind part conically elevated, and armed with two acute divergent black spines, separated by an impressed line. Ocelli wanting. Au- tennffi moderately long, the 4th to the 9th joints short, the re- mainder gradually elongated and black ; first and second green. Protborax quadrate, glabrous, dirty blackish, with a transverse impression in front. Mesothorax rather longer than the pro- thorax ; cream-white, except at its dirty posterior margin, with a very thin central green line. Metathorax and abdomen pitchy and glossy ; three terminal segments of the latter short and compressed ; two anal styles short, slender, and divergent. Operculum thin and flat, not extending beyond the eighth dorsal segment. Tegmina oval, half the length of the wings, slightly elevated towards the base ; black, marked with a large oblong cream-white patch along the costal area, extending into an oval spot on the disc between the middle and base. Wings large and black, with a large triangular cream-white spot extending from near the base to beyond the middle of the wing, and reaching from the costal margin halfway across the wing ; chief vein of the costal area trifid. Legs short, spineless, dirty greenish black ; fore femora slightly curved ; under side of the body pitchy brown, with the metasternum pale dirty white, except at its hinder margin. I have named this species after its discoverer, to whose inde- fatigable exertions in Brazil, English entomologists are indebted for many of the finest acquisitions to their cabinets.
