BY RICHARD H. STRETCH. 795 CHAPTER IX. This collection, though small, is of much interest, as indicating what we may expect from Arizona when more is known of its fauna. Two of the species here enumerated range into Costa Rica and three into Mexico ; two of them as far north as Portland in Oregon, and only one seems to be peculiar to Arizona. This linking of the United States to the tropical fauna of Central America and Mexico may largely swell the list of United States species. Nor should it be lost sight of that while the Mexican forms range into Arizona, the Gulf of California appears to have proved a barrier to their distribution in California. A number of specimens still remain to be identified in this collection. BOMBYCIDAE. ARCTIINAE. EUCHAETES, Harris. EUCU AI5TES ELEGANiS, up. nov , Plate XL, Figs. 5, 6. White. Head and palpi white, the latter rosy at the base, and the former very narrowly rosy behind, particularly near the eyes. Antennae white; pectinations black. Prothorax, patagia, and thorax white. Abdo- men rosy above ; dusky white beneath, with a faint dorsal row of whitish spots, centered with dusky, and a lateral row of black spots. Legs whitish, with the coxae of the anterior pair pale rosy. Wings pure glossy white, immaculate. 797 798 ZOOLOGY— INSECTS. 9 . — Similar to £ , except that the colors of the abdomen are less dis- tinct, and the last segment of the abdomen is tufted with dense whitish hairs, somewhat as in E. egle 9 . Expanse of wings, £ 9, 1.45 inches. Length of body, 0.55 inch. Hab. — Owen’s Valley, California. Described from one £ and 9 in good preservation. In the form of the wings and general structure of the body, this species closely resembles E. egle and E. oregonensis, but the wings are narrower than in E. collaris. The color of the abdomen separates it readily from its allies found in the United States, though there is a very similar Mexican species with a rosy head. Habits unknown. COCHLIDIINAE. LEUCARCTIA, Packard. LEUCAROTIA ALB1DA, Stretch. Plate XL, Figs. 4, 5. 3 . — White. Head and thorax white. Sides of the front next the eyes black. Palpi black, a little whitish below. Thorax beneath white. Antennae black. Abdomen clear yellow-ocher above, except the apical segment and the basal hairs, which are white ; beneath white. Each segment above has a transverse black spot. There is a lateral row of small black dots, and a faint indication of a sublateral row of the same color. Legs white above. Coxae of anterior pair black, fringed with yellow hairs. Inside of femora yellow; those of the middle pair only partially so ; those of the posterior pair only at the apex of the joints ; tips all touched with black. Tibiae of anterior and middle pairs streaked with dusky inwardly ; posterior pair white. Tarsi dusky beneath. Wings pure white, both above and beneath; the anterior pair immaculate ; secondaries showing faint traces of a discal spot and two submarginal spots. Expanse of wings, 1.20 inches. Length of body, 0.80 inch. Hab. — Owen’s Valley, California. 9 . — Unknown. The specimen from which the description is given is in poor preserva- ZYGAEN1DAE— CASTNIINAE-A.DOCTA VAR. ARIZONIENSIS. 799 tion, but may readily be distinguished from L. acrcea , not merely by its smaller size and the absence of markings, which alone in such genera as this would scarcely warrant its separation under a specific name, but by the color of the posterior wings, which are totally different from the well known L. acrcea. It may not be uninteresting to add that I have in my collection a d exactly corresponding to the foregoing description, which I received from Costa Rica through Dr. Van Patten. This gentleman’s col- lection was made in the table lands of the interior. I have also, from the same locality, a large notodontid (?), likewise identical with a specimen received from Arizona ! When it is remembered that I am as yet acquainted with only five species of Bombycina from the district of Arizona and its vicinity, it is somewhat remarkable that two of these should be represented in a locality so widely removed as Costa Rica, and we may naturally look for many striking additions to our list of insects as we become more familiar with this as yet almost unknown country. ZYGAENIDAE. CASTNIINAE. ARCTIA, Schrank. ARCTIA DOCTA var. ARIZONIENSIS, Stretch. Plate XL, Figs. 2, 3. S . — Head yellow-ocher; palpi black; antennae brown; prothorax, patagia, and thorax somewhat hairy, pale whitish-yellow ; the patagia each with a black dash and the thorax with a central black line. Abdomen above pale vermilion ; terminal segments black, beneath black, with a broad ventral pale yellowish stripe. Legs blackish ; coxae of anterior pair hairy, ocher yellow. Anterior wings pale creamy-yellow, with the following reduced black spots : two basal streaks ; three irregularly shaped angular subcostal spots, one of which is on the discal vein, one outside and one inside of the discal vein; two spots on the outer margin, one apical the other on the second meridian ; a submarginal spot between the third and fourth median nervules ; an elongated anal spot and a minute transverse spot on the submedian vein, 800 ZOOLOGY— INSECTS. near the base. The middle subcostal spot is supplemented below the median vein by a very faint transverse streak. Fringes concolorous with wings. Secondaries dirty white, thinly scaled, rosy along the inner margin, with a small blackish discal spot; a submarginal row of three blackish spots, the anal one small, the apical one extending from the costa to the first median nervule. There are also two marginal spots, one near the apex, the other about the middle of the inner margin. Beneath as above, except that the fore wings are nearly white, and the costa of all the wings is decidedly yellow-ocher. Expanse of wings, 1.60 inches. Length of body, 0.65 inch. Hab. — A rizona. Described from one $ received from my friend Mr. W. H. Edwards. The nearest ally of this beautiful species is A. autliolea , Boisduval, which it much resembles. The number and location of the black markings in the primaries is identical, but they are much reduced in size. The chief point of difference is in the black markings on the secondaries, of which there is no trace in A. autliolea $ , while it may prove, however, to be merely a variety when we possess larger suites of these insects. It is at present suf- ficiently distinct to warrant a separate name. AROTIA YARROWII, Stretch. Plate XL, Figs. 1, 2. 5 . — Head clothed with long black hairs. Thorax black, lemon-yellow outwardly. Abdomen black both above and beneath, densely and finely scaled, with an indistinct lateral row of crimson dots. Anal tuft silky, pale ferruginous. Legs black ; anterior pair with crimson coxae ; in the middle pair the tips of the tibiae and the femora are likewise crimson ; on the hind pair the tips of the tibiae and ends of the tarsi are also of the same color. {Note . — The specimen from which this description is drawn has been pressed as flat as a botanical specimen, and the body parts do not admit of a more detailed description. The antennae are wanting.) Anterior wings velvety black, with very narrow fringes and markings as follows of clear lemon-yellow : five angular costal spots, of which the two nearest the base are quadrate ; the third at the middle of the wing- is ZYGAENIDAE— CASTNI1NAE— AROTIA YARROW1I. 801 much narrower ; all of these extend only to the median vein; the fourth is narrow, though wider than the third, and extends across the wing to the anal angle as an irregular hand, being toothed outwardly about the middle at the point where it receives the termination of the fifth short irregular spot or band; below the submedian vein, near the base of the wing and opposite the costal spots 1 and 2, are two small, very reduced spots ; and from the middle of the inner margin springs a very narrow, curved band, which unites with the middle of the fourth spot, forming with it and the fifth the usual terminal Arctian markings. The disposition of these mark- ings is more like that of E. caja or N. plantaginis than any of the strictly American Arctians. Posterior wings full, rounded, rather thinly scaled ; basal half black, bounded outwardly by an irregular line extending from the basal two-fifths of the costa to the anal angle. Outer half orange-scarlet, inclining to orange near the apex. Fringes lemon-yellow. This outer half contains a small black spot on the discal vein, and a submarginal row of three larger black spots. The first of these lies across the interspace above the first median nervule ; the second across, the fourth median nervule ; and the third, on the submedian vein close to the outer margin. There is besides a very narrow marginal spot about the middle of the outer margin. Beneath, the markings are reproduced ; those on the primaries, espec- ially near the apex, being broader and more diffuse. All the light portion of the primaries, except near the apex, are suffused with crimson; this color being most intense near the base and along the subcostal vein. The sec- ondaries are somewhat paler, and there is a crimson streak on the basal third of the costa, which does not appear above. Expanse of wings, 1.75 inches. Length of body, 0.80 inch. Hab. — Arizona. 9. — Unknown. This species, without exception the most beautiful of the American Arctians, cannot be mistaken for any other. It belongs to the section in which the veins are not clearly marked with a distinctive color. The body reminds one of Epicallia virginalis , Boisduval, the under wings suggest the 9 variety of Nemeophila plantaginis with red secondaries, while the ornn- 51 z 802 ZOOLOGY— INSECTS. mentation of the primaries recalls E. caja. It is so unlike any of our other species of the genus that further comparison is unnecessary. It is with much pleasure that I dedicate this beautiful insect to Dr. H. C. Yarrow, the surgeon and zoologist of this expedition, and to whom I am indebted for many kindnesses. EPICALLIA, Hubner. EPICALLIA VIRGINALIS, Boisd. Two specimens were received from Arizona similar to var. guttata, but with rather more ochreous spots on the secondaries, and with the yellow spots on the secondaries rather larger in size than in Californian specimens. MELANCHROIA. MELANCHROIA ? INCONSTANS, Hubner. Melanchroia? ineonstans, Walker, 0. L., B. M., 389. Ardonia secreta , Walker, 0. L., B. M.,, 222, supp. One specimen from Arizona. ALYPIA, Hubner. ALYPIA BIMACULATA, H. S. Agarista Grotei , Boisd., Lep. Cal. (1868-69). One specimen in good condition from Arizona, with the secondaries immaculate. The type of this species was from Mexico. GNOPHAELA. GNOPHAELA HOPPEERI, Grote, var. DISCRETA Stretch. Yar. discreta, var. nov. Two specimens which I have referred to the above species may possibly prove to be specifically distinct, though I prefer at present to consider them merely as a local variety. While resembling G. Hopfferi in form, they are nearer to G. vermiculata , Grote, in color, particularly on the secondaries. The most prominent difference is in the yellowish spot of the primaries, which lies on the discal area. In vermiculata , this is cuneiform, and reaches nearly to the base of the wing ; in Hopfferi , it is quadrate, and does not extend back of the base of the fourth median nervule; while in discreta it is intermediate in form. These specimens were from Arizona, and neither of the previously described forms have yet been received from that Territory. CHAPTER X. REPORT UPO.X THE COLLECTION OF DIPTERA MADE IN PORTIONS OF COLORADO AJNJD .iARIZOLsIAA DUKING THE YEAR 1873. BY C. R. OSTEN-S ACKEN. 803 / > Ifi ■9 V CHAPTER X. Tlie small number of Diptera collected were preserved in alcohol, which renders specimens of this order more or less unfit for scientific pur- poses. Furthermore, the specimens of this collection apparently have been transferred from other bottles to those in which they were ultimately exam- ined, because in many cases only fragments of insects were found, while at the same time portions of the specimens which were wanting could not be discovered in the vials received. Under the circumstances, all that can be furnished is a meagre list of the few capable of identification. The only available specimen in the collection was a fine Lasia (family Acrooeridce), new to science, the description of which is as follows : LASIA KLETTII, nov. sp. Metallic green ; feet black. Long. corp. 17 millimeters.* Altogether metallic green, with golden reflections ; upper side finely and evenly punctured ; venter more bluish ; feet altogether brownish-black ; proboscis black, by one-half longer than the body ; antennae very short, black ; the basis of the third joint slightly reddish ; this joint is more than twice as long as the two first taken together, gradually tapering toward the tip. Wings distinctly infuscated ; tegulse brownish, bordered with black. The specimen having been preserved in alcohol, its metallic surface is entirely deprived of pubescence ; some vestiges on the thorax prove that it was clothed with short pale hairs. Camp Apache, Ariz., September, 1873. Collected by Francis Klett, to whom this species is dedicated. Observation. — I place this species provisionally in the genus Lasia, to which it is related. It differs from Wiedemann's figure of Ladia in the * The measurement, is taken lengthwise through the body, from end to end, without taking into account its considerable gibbosity. \ 805 806 ZOOLOGY— INSECTS. fact that the second longitudinal vein ends in the first and not in the costal vein. It differs from JEulonchus in the eyes being contiguous between the antennae and the vertex only, and not above and below the antennae. The abdomen is very broad, and its upper side very convex ; it is broad and cut squarely at the basis; broad and blunt at the tip (not tapering, as in JEulonchus). The cuts represent this species, Fig. 1, L. Klettii magnified; (the hind tarsi are broken off ; the hair line indicate the natural size). Fig. 2, profile view of the same. Fig. 3, wing magnified.

A number of specimens of this genus were collected in South Park, Colorado, and other localities, in 1873, by Dr. J. T. Rothrock, but, having been placed in alcohol, were in too bad condition for identification. TABANIDAE. TABANUS, Linn. Some few specimens, collected in 1873, in San Luis Valley and South Park, Colorado, by Dr. J. T. Rothrock, arrived in fragmentary condition, consequently could not be identified as regards species. LEPTIDES. LEPTIS, Fabr. A few specimens of Leptis ( Chrysopila ) were secured in 1873 by Dr. J. T. Rothrock in San Luis Valley, Colorado, but could not be identified. It is greatly to be regretted that this collection of Diptera, consisting of thirty lots, on which great pains had been bestowed, should have been ruined while en route to Washington from the field; but under the circumstances the destruction was unavoidable. The collections of preceding years have never been received in Washington. / CHAPTER XI. REPORT UPON THE COLLECTIONS OF COLEOPTERA MADE IN PORTIONS OP NEVADA, UTAH, CALIFORNIA, COLORADO, NEW MEXICO, AND ARIZONA, DURING THE YEARS 1871, 1872, 1873, and 1874. BY HENRY ULKE. 51 z 809 \ \ CHAPTER XI. \ The Coleoptera which have been collected by this expedition abound in specimens, while the number of species is also very large, no less than 389 having been secured, of which five are new to science. From the peculiar character of that part of the country visited (from Owens Valley, California, to Utah, Colorado, New Mexico, and Arizona), this fact might have been expected, and has already been observed by former collectors. In these desert regions there are two families in particular which are very charac- teristic, and whose numerous species represent almost exclusively the coleop- terous fauna of these localities: they are the Tenebrionidce and Mdoida ; the former live on the ground in great numbers and variations, while the latter are found on most every species of Astragalus. Of these vesicants, two new forms have been discovered, which, with some other new species, are described below. DESCRIPTIONS OF NEW SPECIES. BEMBIDIUM NEVADENSE. Plate XLI, Fig. 3.

REPORT UPON THE COLLECTIONS OF HEMIPTERA MADE IN PORTIONS OF NEVADA, UTAH, CALIFORNIA, COLORADO, NEW MEXICO, AND ARIZONA, DURING THE YEARS 1871, 1873, and 1874. Prof. P. R. UHLER. ) u* JgfTHr CHAPTER XII. The specimens of Hemiptera from this expedition, sent to me for exam- ination, are few in number, but they embrace some very interesting species. A Calocoris, which I have provisionally separated from C. rapidus, Say, may be the extreme limit of bright color attained by that species. I sus- pect this to be the case, because specimens of that species, from the less considerable elevations in Colorado Territory, retain the black spots of the pronotum, and some of the fuscous-gray of the hemelytra which obtains in the specimens from the Atlantic region. The Corisas exhibit the minute vermiculate and less distinct marking common to most of the species from Mexico. Chlorocliroa Sayi , St£l, the most beautiful green Pentatomid of the West, seems to find its most conge- nial home in Owen’s Valley, and must be quite abundant there, if we may judge from the large proportion of them brought home by the expedition.

Ovate, polished, bright grass-green above, tolerably coarsely, deeply, and here and there confluently punctured between transverse, wavy rugae ; beneath very finely, remotely punctured, excepting on the disks of the pleural pieces, which are more coarsely punctured. Head as long as the pronotum, triangularly rounded in front, transversely rugulose ; the lateral margins whitish, and more finely and less closely punctured than the vertex ; tylus smooth, very remotely punctured, the tip piceous ; antennae, — basal joint and basal half of second joint green, the apical half of second and the remain- ing joints piceous, pubescent; the second joint longest, the third not more than one-lialf the second, the fourth and fifth shorter, subequal. Rostrum reaching to the base of the third ventral segment, green, with the base, the middle line and the apical joint piceous, second joint very long, reaching from the base of the head to the middle coxae, the apical joint shortest. Pronotum flattened, but with a slightly convex slant forward and sideways ; the lateral margins broadly whitish, bowed ; the anterior angles truncated, to fit against the eyes ; the posterior angles broadly rounded ; the anterior margin broadly sinuated ; the posterior margin straight, but sinuated each HEMIPTERA — COREIDAE — PACHYLIS GIGAS. 831 side at the humeri ; callosities smooth, almost impunctured, bounded behind by an impressed line. Mesosternum slenderly and feebly carinated. Legs green, clothed with long, slender, remote hairs, the tarsi and tip of tibiae piceous ; femora with remote wrinkles. Scutellum broad and blunt, almost flat, the apex broadly white. Outer margin of corium broadly yellowish- white ; the membrane dusky. Tergum minutely punctured, dusky on the disk, excepting two or three of the apical segments. Length, 8-9 millimeters ; humeral width, 4^-5^ millimeters. Taken by Dr. J. T.

After a close examination of other and darker specimens, and on a minute comparison with the original description and with specimens from Mexico, I am enabled to perceive that the name given by me belongs to a pale variety of the species, and must be set aside as a synonym PACHYLIS, Lep. PACHYLIS GIGAS, Burm. Pachylis gigas, Burm., Handb., ii, 338, No. 3. Collected in Southern Arizona by H. W. Henshaw.

I had formerly accepted the determination of Dr. Harris in referring this species to Miris dorsalis , Say ; but after having closely compared speci- mens from many parts of North America with his description, the discrep- ancies are too great to permit such a reference. This species inhabits a large part of North America, and it may yet prove to be only the western form of the European M. laevigatas , Linn. 838 ZOOLOGY— INSECTS. HADRONEMA, Uhler.

REPORT UPON THE COLLECTIONS OF ORTHOPTERA MADE IN PORTIONS OF NEVADA, UTAH, CALIFORNIA, COLORADO, NEW MEXICO, AND ARIZONA, DURING THE YEARS 1871, 1872, 1873, and 1874. BY Prof. CYRUS THOMAS. 8413 CHAPTER XIII. Lieut. Geo. M. Wheeler, Corps of Engineers , U. S. A. : Dear Sir: The Orthoptera which you have submitted to me for exam- ination includes your collections made during the explorations of 1871, 1872, 1873, and 1874. Those of first two years are comparatively small, but those of 1873 and 1874 are the most extensive I have seen from the West, and contain much of value and interest to foreign as well as our own orthopterists. Although the first is small, yet it contains several new species and also one new genus. This genus presents some very interesting features and pecu- liarities. In fact, so important was this deemed, that with your permission a description of it, as well as a few other new species of Acrididce , was pub- lished in the Proceedings of the Philadelphia Academy of Sciences, in order that I might avail myself of this new material for publication in my “Synop- sis of the Acrididse of North America”, which I desired to have as complete as possible for the use of our entomologists. You will see by an examina- tion of my work that I have availed myself of your kind permission in this respect; nevertheless, as this material was obtained by your expedition, I have not only inserted the descriptions here in full, but have also added such remarks as I deemed of scientific interest. This collection is of peculiar interest to me besides, for the following reasons : it contains a specimen in color, and a female of Locusta fuliginosa, Thos., which I described from a single male furnished by Dr. Palmer. As this was the first specimen of Locusta observed in the United States, I was very anxious to obtain the female, and, if possible, a specimen in color. This wish has been gratified by the rcceipt,of your collection. Although some doubt was expressed at the time as to the correctness of my opinion as to 845 846 ZOOLOGY— INSECTS. this being a different species from a specimen obtained in California, I am now able to set all doubts at rest, and state positively that the two are quite different and distinct species. The collections of 1873 and 1874, as will be seen, contain a number of new and interesting species, especially of Calopteni and CEdipodce, but it is somewhat singular that so few specimens of Caloptenus spretus, the destructive grasshopper of Utah and the West, are found in them.- This certainly indicates that the line of your survey was along the southwestern border of its district. In fact, the collection of 1871 did not contain a single specimen, which was somewhat surprising to me, as I am aware from personal knowledge that its migrations extend along the line of the Central Pacific Railroad some distance west of Salt Lake. The absence from the earlier collections of (Edipoda atrox, Scudd., which corresponds exactly with the fact presented by my own collections from Salt Lake north to Montana, is somewhat puzzling when connected with the additional fact that specimens of this species have been found on the mountains about Yellowstone Lake, and also on the mountains in Cen- tral Colorado. This species is found in abundance in California, where it is not only destructive, but to a certain extent migratory. It is therefore quite strange that it should be absent from the intermontane plains and valleys of Utah, Idaho, and Nevada, and yet be found in the higher mountain regions of Colorado and Wyoming. The same thing also appears to be true in regard to some other Californian forms, which reappear in the mountains of Colorado. Your collection also corresponds in another somewhat singular respect with the collection I made in 1871 in Northern Utah and Southeastern Idaho. While the Rocky Mountain range appears to form a boundary to the range of the species of Locustidce, on the other hand, the distribution of the Acrididai appears to be but little affected by it ; for example, Stenobothrus coloradns, which I supposed was confined to the eastern slope and eastern plains, I find in this collection. Qddipoda neglecta, which, although a west- ern species, is found as far east as Illinois, is contained in your collection, as is also CE. cincta, which reaches easftvard to the Mississippi River. Pedioscertctes nevadensis, which is very closely allied to Acrolophitns ORTHOPTERA— LETTER OE TRANSMITTAL. 847 hirtipes (the Gryllus liirtipes of Say), I judge is a southwestern form, which ranges chiefly south and west of the line of your survey, as I have seen it in no other collection. It is possible that Major Powell’s collection, which I have not seen, may contain specimens of this interesting species. Having pinned a mimber of your specimens by the side of a small collection from Southern California, I observed a somewhat singular con- trast in color; the prevailing color of the Calopteni and (Edipodoe from Cali- fornia being a bright yellow, while the corresponding species of your col- lection were largely rufous. I have been inclined to believe, though not fully satisfied on the point, that, in the West, the general or ground color of species which inhabit barren spots, is, to a certain extent, dependent on the color of the surface soil. I find also a specimen of (Edipoda undidata, Thos., which I supposed was confined to the section east of the Pocky Mountain range ; but this col- lection shows that it also belongs to the middle or intermontan e area. I find in the collections of both years a fine large Acridium , which is new, a description of which, by your permission, has been published, and is con- tained in my synopsis. But the most interesting object of the collection is a specimen of Ephippigera tschivavensis, Hald. I have expressed the opin- ion, in my synopsis, that Haldeman’s specimen was the pupa of some spe- cies of (Edipoda ; but a slight examination of this specimen is sufficient to show any entomologist that it is an imago, and that Ilaldeman was right in describing it as new. Other notes in regard to the collection will be found under the proper heading. Since the publication of my Synopsis, I have received from Dr. C. Stal, of Sweden, a copy of his Eecensio Orthopterorwn , published about the same time, which introduces quite a number of changes in the arrangement of the groups of this order. As this author is the leading orthopterologist in Europe, I have thought it proper to call attention to such changes as relate to our Orthopteral fauna. I have also received from Mr. Otto Hermann a copy of his paper on the JDecticidce, recently published in the Verliandlungen der kaiserlich-Jconiglichen zoologisch-botanisclien Gesellschaft in Wien, which contains a friendly criticism on my provisional arrangement of this group of the Locustidff. As the 848 ZOOLOGY— INSECTS. author had sufficient material before him (obtained chiefly from the collec- tion of Dr. Brunner de Wattenwyl) to properly systematize this group, and clear up the confusion into which it had fallen, I have thought it proper to give here his arrangement for the benefit of our entomologists. Allow me to state that your collection has been of much value to me in my investigations of this order, and that I trust the following brief report may be accepted as a partial attempt on my part to repay you for your kindness in submitting it to me. I remain yours, very respectfully, CYRUS THOMAS. LIST AND DESCRIPTIONS. The specimens of 1871, as I learn from the letters of Lieutenant Wheeler and Dr. W. J. Ploffman, as well as by personal communication of Dr. H. C. Yarrow, were collected chiefly along the route of the expedition, from Carlin, on the Central Pacific Railroad, to Cottonwood, in the southern part of Nevada; a small portion only of the collection being obtained in Northwestern Arizona. A portion of this collection is preserved in alcohol ; others are dried specimens, which retain their colors. The collections of 1872, 1873, and 1874 were made in Utah, Nevada, Colorado, New Mexico, and Arizona, by Dr. H. C. Yarrow, Dr. J. T. Roth- rock, Dr. C. Gr. Newberry, Lieut. W. L. Marshall, Mr. H. W. Henshaw, and others of the expedition. BLATTIDAE. The absence of this family from western collections would seem to indicate at least that it was not well represented in that section. This also corresponds with my observations in the sections I have visited. I do not think I have seen a dozen specimens in all the collections I have examined. I do not find a single specimen in this collection. MANTIDAE. There are three specimens belonging to this family in the collection, one of which is new, and is named in honor of Lieutenant Wheeler, in charge of the expedition. ORTHOPTERA — MANTIDAE — MANTIS WHEELERII. 849 MANTIS, Linn. MANTIS WHEELERII, sp. nov. The specimen is dry, and is so badly damaged that it is impossible to determine positively the genus to which it belongs, or to do more than indi- cate some of its leading specific characters. Female. — Head flat, transverse, triangular in front. Occiput short, reduced to a transverse ridge. Vertex transverse, directed downward and backward toward the face, with four slight longitudinal depressions. Ocelli distinct and prominent. The face transversely quadrilateral ; the upper carinate margin bent upward between the antennae. The antennae wanting. Prothorax about twice the length of the rest of the thorax ; the margins minutely serrate, slightly emarginate, scarcely expanding posteriorly, ex- panding near the transverse incision. Anterior femora denticulate on the exterior carina. Abdomen enlarged, fusiform. Middle and posterior legs wanting, and but a remnant of the wings remaining. Color. — Yellow, probably faded from a pale green. The abdominal segments with a piceous black fascia or ring on the posterior margin of each. The remnants of the wings carneous-red. It is probably a species of Stagmatoptera ; but it certainly approaches very near to Hierodula, notwithstanding Saussure’s assertion that those be- longing to the genus are “ Insectes asiatiques et africains”.* The specimen is too much injured to give any very accurate measure- ments ; but the following approximations will indicate the size : — Length, 2.2 inches; prothorax, 1.0 inch; anterior femora, 0.5 inch ; anterior tibiae, 0.6 inch. Stal ( Ofver . k. Vetensk.-Akad ., 1871) gives a new arrangement of the Mantidce in the form of a synoptical table. Although this possesses some advantages in tracing species, yet I prefer that of Saussure, as given in his Melanges orthopterologiques (3 ln0 fas., 1870). .He divides the family into two divisions, which he terms groups , but which might very properly be called subfamilies. The first, Nudipedes , is distinguished by setaceous antennae in the two sexes ; head triangular, simple, without prolongations ; feet and body simple, without membranous 54 z * Melanges Ortbopterologifjues III, Fascic. 214. 850 ZOOLOGY— INSECTS. appendages ; elytra oval or lanceolate with entire borders. The second, Lobipedes , is distinguished chiefly by the appendages found on some part of the body or feet. The former group is divided into two tribes, Orthoderii and Mantii; the former having the prothorax straight, the sides parallel, and the front not attenuate, while the latter has that portion of the prothorax over the ante- rior coxae more or less expanded, and the front attenuate or convergent. The three species here mentioned belong to the latter tribe. This tribe is separable into two divisions distinguished by the form of the super-anal plate ; in the first ( Mantites , Sauss.), it is transverse, or in the form of a short triangle; in the second ( Thespites , Sauss.), it is elongate- triangular or lanceolate. Saussure, in his synoptical table of the genera of the Mantii , groups the genera under the following headings : — I. Super-anal plate transverse, or a short triangle Mantites. a. The discoidal vein of the wing of the $ 9 undivided or furcate. aa. The discoidal vein of the wing of £ ramose : b. Species small ; prouotum short. bb. Species large ; pronotum more or less elongate ; body robust ; abdomen rhomboidal or fusiform or narrow : c. Elytra of the 9 squsemiform. cc. Elytra and wings of the 9 complete. It is to this last subdivision, embracing some six or seven genera, that the species in this collection belong. MANTIS (?). It is possible this is new ; but as it bears a strong resemblance in some respects to M. Carolina, I have not ventured to describe it as a new species from the single alcoholic specimen before me. Female. — Elytra greenish-yellow, unspotted; stigma small, oblong, same color ; extending to the margin of the penultimate segment of the abdomen. Wings similarly colored, with yellow interneural fasciae ; dis- coidal vein furcate. Stature that of M. Carolina. These characters would appear to place it between Car diopter a and Stagmatoptera ; it may belong to the southern form of Stagmomantis Carolina which Saussure has separated as a distinct species, it is therefore impossible to determine accurately its position without the male. ORTHOPTERA— ACRIDIDAE— INTRODUCTORY REMARKS. 851 MANTIS (?). This specimen is very much mutilated ; the greater portion of the abdo- men is wanting. It is possible that it is but the pupa of the previous spe- cies, to which it is evidently closely allied. PHASMIDAE. Two specimens of this family are contained in the collection, and, although not in a condition to be specifically determined, yet it is evident that they are quite distinct. ACRIDIDAE. INTRODUCTORY REMARKS. Most of the specimens collected belong to this family, and are the most interesting on account of the new forms brought to light. I find in the col- lection no representatives of the group Tryxalini , as this group is limited in my Synopsis, nor have I seen any representative of it west of the Rocky Mountain range, except two or three larvae of what I supposed to be a species of Opomala. So far as the number of species is concerned, the (Edipodce appear to be more abundant than the Acridii. As Still’s “Recensio Orthopterorum ”, heretofore mentioned, relates wholly to this family, I have concluded to introduce what I have to say in regard to it at this point. And first I may state that I am as yet unable to ascer- tain positively which has priority in date of publication, the “ Recensio ” or my Synopsis. The title page of the former bears date 1873, which is also the date of the latter. The author quotes his own paper published in Ofv. Kongl. Vet. AJcad.-ForJiandl., No. 4, 1873. By reference to this paper, which, with the “ Recensio” has been kindly communicated to me by the author, I find that it was presented April 16, 1873. As it is probable it was not published for a month or so after it was presented, I infer that the “Recensio” , in which it is quoted, did not make its appearance until in the latter part of the year. My Synopsis was actually published (distributed) about the first of October, 1873. It is therefore a matter of doubt as to which has precedence in date of publication; and until this is settled by ascertaining the exact date of the publication of the “ Recensio ”, I shall retain 852 ZOOLOGY— INSECTS. the names I have adopted in that work where they relate to the same divis- ion, genus, or species, except where I find that I am in error. It is proper to remark here that this work relates almost exclusively to the species named by Linnd, De Geer, and Thunberg, yet the author seizes the occasion to present a somewhat detailed synopsis of his arrangement of the family. While I cannot agree in every respect with this arrangement, yet I think it must be admitted that he has made a marked advance in sys- tematizing this troublesome family, and that entomologists must adopt much that he lias presented. Although I am inclined to think my own arrangement should be some- what modified, I cannot adopt his division into eleven subfamilies, if they are intended to stand as divisions of equal value, or as representing corre- sponding variations. The grouping does not differ very materially from that of most recent authorities, although the characters used as his chief guides are somewhat different. This would indicate that the larger groups, as now established, are natural, as the same result is reached, no matter from what stand-point our investigations are made. In my synopsis, I have divided the family into two primary divisions, which I call, and I think correctly, subfamilies, while the next divisions, corresponding, in part, with Stal’s, I have termed groups. This method, I think, corresponds more closely with the nature of the characters that sep- arate these divisions, and renders the arrangement more systematic than either that of Walker or Stal. The subfamilies given by Dr. Stal are as follows : — PliymatidcB; Pamphagidce ; Acridiidce; Truxalidat ; (Edipodidce ; Pneumoridai ; Godopternidce ; Tittigidce ; arranged in the order here given ; also Proscopidce, Mastacidce, and Choree - typidee , whose position in his system the author does not give. ORTHOPTERA— ACRIDIDAE— INTRODUCTORY REMARKS. 853 Although the author, in his diagnoses of these groups, reveals the fact that the distinctions in one case are greater than those in another, yet so far as the arrangement and naming is concerned they stand as equivalents. No one will contend for a moment that the difference between Acridium and Edipoda is as great as between either of these and Proscopia or Tcttix. Yet Dr. Stal’s system does not indicate this fact, as his groups stand as equivalents. If we compare the true Acridians, as Acridium , (Edipoda, &c., with the Tettigi , we find the following differences : — Acridii. — Of various sizes, from half an inch to four inches in length ; wholly terrestrial in their habits* Tarsi furnished with a pulvillus, or pad, between the claws ; although sometimes minute, yet it is seldom, if ever, absent. Pronotum consisting of a kind of shield, covering the prothorax and extending backward at farthest only upon the base of the elytra. Prosternum drawn up ; that is, it is not in the same plane as the rest of the sternum ; spined, tuberculate or smooth, but never advanced upon the mouth. Mouth free, not covered by the prosternum. Elytra and wings generally present, but sometimes aborted or entirely wanting ; but, when present, the latter never exceed the former in length. But an examination of the Tettigi reveals an entirely different set of characters in all these respects, as may be seen from the following statement of them : — Tettigi. — Generally of small size, many being less than half an inch in length, and seldom exceeding an inch, preferring moist damp situations, and in some cases even subaquatic. Pronotum forming a shield over the entire body, extending backward nearly or quite to, and often beyond, the tip of the abdomen ; sometimes flat, sometimes keeled and arched, and in some species elevated into a sharp foliaceous crest. Tarsi without pulvilli, or pads, between the claws. Prosternum depressed to the same plane as the rest of the sternum ; advanced upon the mouth, and usually furnished with a kind of semicircu- 854 ZOOLOGY— INSECTS. lar ridge, which forms a sort of muffler, into which the mouth is drawn when at rest. Mouth covered by the advanced portion of the prosternum. Elytra and wings , when present, generally placed upon the sides of the body, the latter exceeding the former in length ; these organs being appa- rently pushed upon the sides by the extended pronotal shield. These differences in the external structure, which all must admit are important, are accompanied by certain modifications of the internal struc- ture, and certainly indicate important variations in habits. Now, if we compare the species of Stal’s subfamily Acridiidce with those of his QZdipodidce, or any other true Acridians, we shall find the tarsi in each case furnished with a pad between the claws ; the shortened, shield-like pro- notum ; the prosternum drawn up ; the mouth free ; the elytra, when pres- ent, always equal to or exceeding the wings in length, and generally meet- ing or overlapping each other above the abdomen. It is therefore clear that the true Acridians and the Tettigi are more widely separated from each other than the groups of the former ; and a true arrangement ought to indicate this difference. For these reasons, I still hold that the Tettigi should be separated as a subfamily, and that the other groups of the true Acridians should be considered as subordinate divisions. It will be observed that I have admitted that my arrangement should probably be somewhat modified ; also, that, in speaking of certain groups, I have used the expression “ True Acridians”. My reason for this is that a more thorough examination of exotic forms has convinced me that the Pro- scopice constitute a distinct subfamily, equivalent to the Tettigi. Whether the MastacidcR should be embraced in the same division as Stal in effect does in his Conspectus of his subfamilies, I am unable to say ; but I have consid- erable doubt as to the propriety of this course. A single glance at a typical species of Proscopia is sufficient to reveal even to a superficial observer important variations from the true Acridian type. Their elongate, cylindrical bodies, long, slender legs, and general appearance would lead us, at the first glance, as it did Stoll, to place them among the apterous Phasmce. In fact, Ceplialoccema subaptera , West (Arcan. Ent., ii, 55, pi. 63, fig. 2), might easily be taken by the unscientific ORTHOPTER A — ACRIDID AE — INTRO D U CTORY REMARKS. 855 observer for our common Diaplieromera Sayi. Not only is the body elongate, slender, and somewhat cylindrical, but is generally almost uniform in size throughout its length, and usually wingless. The head is elongate-conical, and either ascending obliquely ( Proscopia ), or extending forward horizontally ( Ceplialoccema ) ; antennae very short, often falling short of the tip of the vertex, and composed of but few joints (six to nine). The legs are quite slender ; the posterior pair being scarcely fitted for leaping. The prothorax is very long, slender, and subcylindrical, having no pronotum in the sense of a shield, as seen in the true Acridians ; the pronotum here being simply the dorsal portion of the prothorax as in the Pliasmce\ the anterior legs (in Proscopice ) are attached to the sides near the middle. The meso thorax and metathorax are very short ; their combined length seldom equaling one-half the length of the prothorax. It is evident from these characters, and others which might be named, that the distinctions between this group and the true Acridii are much greater than those which separate the groups into which the latter have been divided. I am therefore inclined to think this group should be considered as a subfamily, and as equivalent to the Tettigi. We should, then, have three subfamilies, as follows : — Proscopiisle, Acridine, and Tettigin,e. Therefore, while I think the arrangement given in my synopsis should be thus modified, on the other hand, the reasons which lead me to this con- clusion would also lead me to reject the plan suggested by Dr. Stdl, if his larger groups are to be considered as subfamilies. Raising his Proscopidce and Tettigidce to subfamilies, and considering the rest of the family as a third subfamily, I am prepared to accept, in great part, his other groups, if considered as inferior divisions. I most heartily agree with him in suppressing Walker’s Trlgonoptcry- gidce, and in raising Pneumorm to a distinct group, as equivalent to Acridini and (Edipodini . And, to show that, I had arrived at this conclusion before the receipt of the “ Becensio ”, I quote ^he following from my notes prepared during the winter of 1873-74 : — “ This singular group (Pneumorce) presents some very singular features, 856 ZOOLOGY— INSECTS. &c Although these divarications from the typical form are con- siderable, and possibly may require their separation into a distinct group, as I have used the term in my classification, yet I do not think they will justify raising the division to the dignity of a subfamily.” In regard to the Trigonopterygi , I quote the following from the same notes : — “ Trigonopte'ryx has a conical, somewhat ascending head; an oblique but incurved face, and ensiform antennae, and if the wings were of the usual form would doubtless be placed in this group ( Tryxalini ) by all entomolo- gists. The same remark may be made in regard to Hyalopteryx , Charp. If we place the former in a separate group, or limited family, as has been done by Walker, and in which I have followed him improperly in my Synop- sis, on account of the unusual elytra, how shall we avoid the necessity of forming a separate group for Sphenarium , which has but figments of elytra, unusual in form and neuration, attached to the sides of the thorax ? Trigo- nopteryx is essentially tryxalidian in form and features, and should be included in this group ( Tryxalini ) ; therefore I feel compelled to correct my former work in this respect.” Notwithstanding Dr. Brunner Wattenwyl approves of the character chosen, which forms the chief ground for separating the Pliymatidce from Pamphagidce, yet I doubt the propriety of forming two divisions. Placing Mastax in a separate group or division is certainly correct. I know nothing in regard to the species on which he bases his subfamilies Ccelopternidce and Chorcetypidce. Before speaking of the genera which the author embraces in his sub- families, I desire to call attention to the order in which he arranges these subfamilies, which has been given on a previous page. The author does not state positively that this is the order in which they should stand ; but it is the order in which they are placed in the body of his work. In his Conspectus, they stand in the same order, Proscopidce standing at the head ; Mastacidce second ; and, then, as given, down to Pneumoridce ; then follows Chorcetypidce ; after that the other two as given. As the order in the body of the work, so far as given, corresponds with that in the Con- spectus, it is probable that this forms a correct outline of his arrangement. ORTHOPTERA— A CRIDIDAE— INTRODUCTORY REMARKS. 857 It is evident that by this arrangement the groups, with perhaps two exceptions, form as close connections on each side as is possible ; for exam- ple, the connection of Acrididce with Truxalidce is natural, as is that of the latter with CEdipodidce. By reference to my Synopsis (page 144), it will be seen that I also maintain this bilateral connection of the Tryxalides, placing Xiphocera on the side next the Acridii as the connecting link. But I there place the Tryxa- lides at the head, and the others as the parallel links of two descending or ascending lines. If St&l intends Proscopidce to stand before Phymatidce as the connecting link between this family and Phasmidce, and he can scarcely do otherwise, then his arrangement will be somewhat in the form of a recurring series : beginning with the elongate conical head and slender form in Proscopia, he passes through the gradually shortening and swelling forms of the Phyma- tidce, to the large lubberly Pamphagus elephas , which, by its size and unwieldy appearance, reminds us strongly of the Brachypeplus magnus of our western plains. When he reaches his Truxalidce, he again has the conical head and slender body, which again recedes from view when he enters the CEdipo- didce. It is evident therefore that this linear arrangement depending on one or two characters, no matter how permanent, is not in accordance with nature. There are evidently diverging lines, and Dr. Stal’s work has ren- dered it quite probable that there are three of these lines instead of two, as I have given ; and this also increases the evidence in favor of Dr. Scudder’s idea as to the ascending order of the families, as it indicates the conic head and slender form as the more generalized, as it is the converging point of three different lines. While I am compelled to admit these facts as against my view as to the position in the scale of being, yet it but increases the difficulty at the other extremity of the family. I am satisfied that no arrangement can stand the test of future investi- gations 'which separates the Proscopice and Tryxalidce so widely as Dr. Stal has done, no matter how satisfactory it may be in other respects. While I am fully conscious of the difficulties experienced in attempting to arrange the subdivisions in a continuous line, at the same time I consider it very doubtful whether success in this respect is advantageous or in accord- 858 ZOOLOGY— INSECTS. ance with nature, if, while harmonizing the parts of a group with each other, we tear asunder the links which bind it as a whole to other adjacent groups. Moreover, I believe it is now generally conceded that, in ascending the scale of being, we pass, as a general rule, from the generalized to the special- ized, and find the lines we are tracing repeatedly branching and forming other lines. Without attempting at present a further review of the author’s general arrangement, I will call attention to such changes in his work as relate to our North American orthopteral fauna. Sphenarium, IcJitliydion , and Pyrgomorpha are transferred to Phymatidce. The last named genus as he has limited it, and in fact the characters of tins subfamily as he has given them, excludes our P. brevicornis, which, as will hereafter be seen, has been retained in Truxalis * His subfamily Acridiidce includes the following genera, which have usually been placed in other divisions: — Xiphocera , Tropinotus , Didyophorus, Bhomalea, Mesops, and Opsomala. Our Bhomalea centurio ( microptera ) is retained in the Dictyophorus of Thunberg as D. reticidatus, the name given to it by that author in 1815. This genus, as now limited, is distinguished by the following characters : — The vertex and fastigium lying in the same plane and slightly declined, and seen from the side forming a right angle with the frontal costa ; prono- tum obtusely carinated; anterior margin forming an obtuse angle or rounded. Bhomalea is limited to the species possessing the following characters : — The transverse impressions of the pronotum distinct ; anterior lobe destitute of a carina; posterior lobe depressed, but ascending posteriorly; frontal costa suddenly flattened below the ocellus. In this, he places B. miles , Burm., but restores the specific name speciosa of Thunberg ; Acridium colo- ratum , Serv. ( Chromacris colorata, Walk.), is also included. His specimen of the latter species is from Mexico ; it is therefore probable that the locality (^Carolina) given by Serville for his specimen is a mistake. The author also introduces a new genus ( Tceniopoda ) into this rhoma- lean group, which has the following as its distinguishing characters: — Fasti- gium strongly deflexed, forming with the frontal costa as seen from the side * The reader will notice that, in speaking of Stal’s genera and subfamilies, I retain his method of spelling. ORTHOPTERA— ACRIDIDAE— INTRODUCTORY REMARKS. 859 an obtuse, somewhat rounded, angle ; pronotum cristate, the crista on each lobe near the posterior sulcus depressed. This includes the R. equita , Burm., Monachidium superbum, St&l, and JR. pecticornis, Walk. Stal describes the last named species as new under the name T. picticornis. This collection contains several specimens of this fine species, which will be noticed at the proper place. St&l’s division of this heterogeneous group into different genera is emi- nently proper; for a single glance at R. microptera and R. miles is sufficient to convince any entomologist that they are generically distinct. As the Dictyophorus of Thunberg has precedence in date, its restoration must be acquiesced in. The Lophacris of Scudder is included under his Titanacris, which the author distinguishes from Tropidacris chiefly by the venation of the elytra and form of the genital plate of the male; being entire in the former and emarginate in the latter. At this point, a new genus (Hermistria) is introduced, founded on a species from Mexico. This and the other new North American species men- tioned will be noticed in this paper at the proper places. The change which, if followed, will produce greatest confusion in our American nomenclature is that in reference to the caloptenoid species. He holds, as I learn by letter from Dr. Brunner de Wattenwyl, that we have no Calopteni in North America; all our species being referable to Pezotettix. Serville’s name ( Calliptamus ) is amended and retained as Calliptenus. The chief distinctions given by the author between this genus and Pezotettix are as follows : — In Calliptenus, the elytra destitute of the intercalate vein ; the pos- terior femora broad and distinctly serrate above ; the posterior sulcus of the pronotum in the middle or before the middle. In Pezotettix, the elytra abbreviated or rudimentary, and furnished with an intercalate vein ; posterior femora having the upper margin entire and unarmed ; posterior sulcus of the pronotum sometimes situated behind the middle. His numerous divisions of these restricted genera into subgenera show clearly the difficulty experienced in attempting to obtain a satisfactory 860 ZOOLOGY— INSECTS. arrangement. It is clear that if we follow the diagnoses of these genera as given by him, all of our Calopteni will have to be removed to other genera. C. femur-rubrum is placed in Pezotettix under the subgenus Melanoplus , and, as a matter of course, must carry with it C. spretus, and other closely allied and congeneric species. St&l is undoubtedly correct in subdividing Serville’s genus, as that author, in his Histoire des orthopteres, recognizes two quite distinct groups. But the question arises here as to which subdivision the name should be applied. The genus was formed by the author, and first used by him in his Revue methodique des orthopteres (1831) for the reception of three species, C. italicus , morio, and sanguinipes. It is true that afterward (1839), in his Histoire des orthopteres , Serville removed C. morio to AEdipoda, as it was in fact no Acridian, and had been previously named by Creutz (Entom. Versch.); also that he returned C. sanguinipes to Acridium, thus leaving C. italicus as the only original representative of his genus. But, in the mean time, Burmeister* changes the name to Caloptenus, and includes in the genus, as limited and understood by him, not only italicus , but also the American species femur-rubrum , femoratus, and bivittatus, besides a number of other exotic species. If Serville’s name was erroneous, then Burmeister was as fully authorized to correct it as Dr. Stal, and it comes from the hand of either really a new genus. But not only this : Serville includes three species which are incongruous, each of which had been pre- viously named, and two of which he afterward, in his Histoire des orthopteres , removes. Stal speaks of this contention in regard to priority as puerile and derogatory to science ; yet he clings to the name given by Serville, although it is erroneous and has to be emended, making C. italicus the type. Under these circumstances, and following out the spirit of his own advice, as given in his introductory remarks, I shall not follow him in this respect, because I do not think even the strictest construction of the law of priority requires it, and because to do so would inflict upon our nomencla- ture a host of synonyms which can be avoided by retaining the name Caloptenus , as given by Burmeister. Some of the species may have to be removed to other genera. It is true that the peculiar characters selected * I am aware that sorno doubt as to priority iu date of the Handbucli der Entomologie aud Histoire des orthopteres has recently been expressed ; but so loug as it is generally conceded to the former, our conclusions in regard to nomenclature must be based upon that assumption. ORTHOPTERA— ACR1DIDAE— INTRODUCTORY REMARKS. 861 by Dr. Stal may map the ground into areas whose lines fall wide of those heretofore given ; but before we follow this, we must be convinced that his characters group according to nature. Dr. Gill, if I recollect rightly, remarks, in the introduction to his arrangement of the Fishes, that a charac- ter or series of characters which may be used in one group or even part of it as a correct guide may fail to indicate the true relation of species at another point. Dr. Stal is doubtless fully aware of this fact ; but it appears to me he has neglected at some points to act upon it, and has maintained his plan somewhat arbitrarily. Still I do not feel authorized to take direct issue with him without further opportunity for examination, but simply wish to be understood as saying that the change his arrangement requires in the group now under consideration is too great to be made without better reasons shown than those presented in his work. Opsomala, Serv. ( Opomala , Scudd.), is torn into fragments, and scattered hither and yonder. 0. filiformis and 0. marginicollis, Serv., are placed in a new genus, Leptysma , belonging to Acridiidce , which has no marked or prom- inent character to distinguish it ; that of the head being longer than the pronotum forming one of the principal features. But those who have paid any attention to this group know how unsatisfactory this character is. A new genus, Arnilia , is established by the author for the reception of his 0. cylindrodes, with which he places two specimens from Carolina. The latter, I presume, belong to Stenacris chlorizans , Walk. (Mesops chlorizans, Thos.). 0. bivittata , as Dr. St§l informs me by letter, is probably his Mermiria Belfragii , a new genus belonging to his Truxalidce , and a species from Texas, which he has described as new; but his description leaves it doubtful whether he is correct in this opinion. The following changes occur in Truxalidce : — Oxycoryphus , Gomphoccrus, Stetheophyma, Stauronotus, and Epacromia are transferred to this division. So far as this change relates to Oxycoryphus , Gomphocerus, and Epacromia , I can heartily approve of it, and I find, by reference to my notes heretofore men- tioned, that I have already transferred Oxycoryphus , Pedioscertetes , and Chry- sochraon to Tryxalini. The old name Acrida of Linnaeus is restored for the typical Truxalides 862 ZOOLOGY— INSECTS. and Truxalis is retained in the Fabrician sense with T. brevicornis (our Pyrgomorpha brevicornis ) as its type. If these old names, which have been so long ignored, are now to be restored, then St&l is correct in replacing Acrida ; and, although I doubt the expediency of such a course, yet, as the law of priority justifies him, entomologists will probably accept the change. But if this rule is to be rigidly enforced, what excuse has he to render for utterly ignoring Walker’s new genera and species where he is correct ? Stal describes as new Scudder’s Cliloealtis viridis under the name Trux- alis angusticornis. He describes a new species of Achurum from Mexico, and informs me that he thinks my Tryxalis brevipennis belongs to the same genus. I think it very probable he is correct in this. Saussure’s Oxycory- plius montezuma is transferred to a new genus, Syrbula , in which is also placed a new Texan species. Stenobothrus is wholly ignored, and Gomplio- cerus , which he appears to have used in Freg. Fug. Besa, in the sense in which it is used by Borck, is here scattered among a number of new genera. He gives Stetheophyma, Fisch., Arcyptera, Serv., Chrysochraon, Fisch., and Gomphocerus, Thunb., as synonyms. Stenobothrus viatorius, Sauss., is removed to a new genus, Scyllina, which has for its chief character the inequality in length of the spines of the poste- rior tibiae. In (Edipodidce , the following changes are worthy of notice, and are of interest to American entomologists. Tragocephala of Harris is retained with T. viridi-fasciata as the type ; and CE. sordida, Burm., and (E. costalis, Scudd., are transferred to it. Tomonotus of Saussure is ignored, and a new genus, Arphia, established for the reception of the following species found in the United States : — T. sulphureus and T. tenebrosus; the latter being described as a new species under the name A. sanguinaria. I can see no possible excuse for this new genus, which corresponds very closely in its characters with those given by Saussure, and especially as given in my Synopsis. If the Acrida of Linnaeus and Calliptenus of Serville are to be retained at every sacrifice of convenience, why is it that the genera established by living authors are treated so cavalierly ? There is no more reason why a Linnaean or Tlnmbergian genus should be retained than one established by a living author. In this case, I think Stfil’s apparent desire to furnish new names to ORTHOPTERA— ACRIDIDAE— INTRODUCTORY REMARKS. 863 science has carried him a step too far, and, as I think he is wrong here, I cannot follow him. A new genus, Cawmula, is established for the reception of a species from Vancouver’s Island. This species, which the author says is very simi- lar to Tragocephala sordida, I am inclined to believe is my Tr. pacifica. E. discoidea, Serv., is removed to Hippiscus. This change I can readily concur in. Edipoda is very properly restricted to but a small portion of the hete- rogeneous mass which has been thrown into it, for which entomologists have reason to thank the author. Our (E . Carolina is retained, and appears to be his typical genus ; this retains (E. trifasciata, Say, and (E. undulata , Thos. A new species from Illinois is described under the name (E. Belfragii , which is probably my (E . cincta. A new species from Mexico, CE. punctata , is also described. E. fenestralis, Serv., is removed to a new genus, Psinidia, in which also two new species from Texas are placed. CE. maratima , Harr., is removed to Tremerotropus, also a new genus. No important change appears to have been made in the Tettigidce. Although the author of this work has made a number of changes which I do not think entomologists can accept, as well as some which appear to be unnecessary, yet it must be admitted that he has rendered an important service to science in splitting up some of the heterogeneous and unwieldy genera as Edipoda , &c., and especially in properly determining and locating the Linnsean, De Geerian, and Thunbergian species from an examination of the specimens. It is to be regretted that, while he has such scrupulous regard for the generic names of Linn^, De Geer, and Thunberg, he should occasionally fail to give the proper credit to modern authors, wholly ignor- ing, as he states to me in a letter, the work of Walker, as this will necessi- tate a change by some future orthopterologist. It is true the catalogue of Walker is of but little value; yet, so far as it is correct, it should be accepted, no matter how much chatf surrounds the wheat. Accepting this author’s changes in the larger groups so far as I con- sider them correct, and making the modifications I have suggested, my arrangement of the divisions of the family would then be as follows : — 864 ZOOLOGY— INSECTS. I. Subfamily PROSCOPIN^. 1. Group Proscopini. 2. Group ( Mastacini ). II. Subfamily AORIDINiE. Division 1 . — Conocephalides. 3. Group Tryxalini. Division 2. — Orthoceeides. Division 3. — Xiphooerides. 4. Group (Edipodini. 6. Group Phymatini. 5. Group Acridini. 7. Group Pampliagini. Division 4. ( ?.) 8. Group Pneumorini. 9. Group ( Chorcetypini ). 10. Group ( Ccelopternini ). III. Subfamily TETTIGINAE. 11. Group Tettigini. Those included in parentheses are introduced provisionally, as I am unacquainted with the species forming them. So far as I am aware, only the third, fourth, fifth, sixth, and eleventh groups are represented in the North American fauna. In connection with the list of the species found in the collection under examination, I will give short descriptions of the new North American genera and species described by Stal, and also give the new positions of some of the hitherto described species, under the foregoing modifications. Subfamily ACRIDINAE. TRYXALINI. I cannot, with my present knowledge of the genera, accept Stal’s removal of Mesops and Opomala from this group. It is probable that the species I have placed in Mesops may have to be removed to other genera, and the name retained for other species which belong elsewhere. I shall also transfer to this group Oxy cor y pirns, Acrolophitus, Pedioscertetes , Chryso- chraon, Stenobothrus , and Gomphocerus (the two latter should probably be united into one genus).

St&l’s restoration of Acrida for the typical Tryxalidce , and retention of Tryxalis for its earliest signification, will restore this species to the position assigned it by Fabricius. He has also identified De Geer’s A. ensicornu with this species by an examination of the original specimen. I have deter- mined, beyond any reasonable doubt, that the Tr. notochlorus , of Pal. Beauv. is the male of this species. My P. punctipennis (Synop., 68) is but the female of this species ; conse- quently this name will have to be suppressed. ACHURUM. This genus should now precede Tryxalis in a linear arrangement. The following new species from Mexico is described by St&l : ACHURUM ACRIDODES, St&l. Achurum acridodes , Stal., Recens.

Fusco-testaceous; vertex, dorsum of the pronotum, and anal area of the elytra greenish ; cheeks and lateral lobes of the pronotum near the dor- sum obscure ; elytra griseo-hyaline, except the anal area, which is veined with fuscous; wings dusky. $ , length, 27 millimeters. Closely allied to A. Sumichrasti, Sauss., but differs in the color of the dorsum of the pronotum, and in the dorsum not being alutaceo-rugose, but on the front and posterior lobe is obsoletely punctate, and the lateral lobes being obsoletely variolose. Elytra a little shorter than the body, more than twice the length of the posterior femora ; anal and axillary veins free. 55 z 866 ZOOLOGY— INSECTS. Posterior femora not extending to the tip of the abdomen. Antennae slightly narrowed at the apex, extending beyond the tip of the pronotum. Genital segment of the male elongate and acuminate. MERMIRIA, Stal. This new genus is introduced here, and the description copied from the Becensio , as the single species described under it is the one to which Stal is disposed to refer Opomala bivittata. Generic characters. — Posterior tibiae armed with numerous spines ; those on the exterior margin numbering from eighteen to twenty-two. Head equal to, or but little shorter than, the pronotum ; fastigium prominent ; the frontal tempora (lateral foveolae, or spaces of the vertex) not or but obsoletely separated. Base of the very obtuse (subtruncate) anterior lobe not shorter than the posterior. Elytra and wings not so long, or but slightly passing the apex of the abdomen ; apex rounded. Frontal costa flat ; mar- gins sometimes subcallous. Antennse ensiform ; prosternal tubercle obtuse, distinct, strongly elevated in the middle ; eyes shorter than the portion of the cheeks below them. . MERMIRIA BELFRAGII, St&l. Mermiria Belfragii, Stal, Recens. Orthop., 1873, 102. Pale olive-green, Head greenish-white ; median carina of the prono- tum and an interior vitta of the lateral lobes fuscous ; the lateral carinae pale. Elytra griseo-hyaline, greenish externally and yellow-veined inter- nally ; anal and axillary veins pale. Wings near the base pale greenish- yellow, near the apex fuscous-veined. Spines of the posterior tibiae black at the tips. S . — Length, 44 millimeters. Texas. A vitta on the cheeks behind the eyes pale fuscous ; two olive-green lines on the vertex ; fastigium narrow in front, rounded at the apex, slightly impressed near the margins, shorter than the eyes. The portion of the cheeks below the eyes somewhat longer than the eyes. Face obsoletely and frontal costa distinctly punctate. Antennae broadly ensiform, some- what narrowed at the apex, as long as the head and pronotum. Pronotum, or the dorsum, slightly convex transversely ; lateral margins parallel ; the ORTHOPTERA— AORIDIDAE— P. NEVADENSIS. 867 front and the posterior lobe punctnlate ; this lobe shorter than the front lobe ; lateral lobes anteriorly and posteriorly punctate. Elytra extending to the apex of the posterior femora ; apex very slightly narrowed and sub- rotund ; the anal and axillary veins connect not far from the base. Posterior femora extend somewhat beyond the apex of the abdomen. PEDIOSCERTETES, nov. gen. Pcdioscertetes , published in Proc. Acad. Nat. Sci. Phila., 1873, by permission. Occiput somewhat ascending ; vertex rises obliquely in front of the eyes in the form of a triangular pyramid. The dorsum of the pronotum and head as seen from the side taken together form a regular curve from the posterior extremity of the one to the tip of the other, the concave side being upward The vertex as seen from above is triangular, convex above ; no median or lateral foveolae ; the tempora represented only by a slight depression on the deflexed margin. Frontal costa distinct above the ocellus, fading below ; face sub'oblique and slightly incurved. Pronotum regularly expanding posteriorly, subtricarinate, the front lobes being rounded so as to render the lateral carinse nearly obsolete ; median carina absent or but a minute line ; front margin truncate ; hind margin rounded ; the three trans- verse impressions distinct, close together, and occupying the second fourth, the posterior sulcus being about the middle. Elytra and wings normal, extending a little beyond the tip of the abdomen. Posterior femora slender, but slightly enlarged at the base ; upper and lower carinse slight, entire, unarmed, not quite reaching the tip of the abdomen in the female ; tibiae fully as long as the fermora; spines not very numerous ; first joint of the posterior tarsi as long as the other two. Metasternum broad ; prosternum narrow, unspined. PEDIOSCERTETES NEYADENSIS, sp. nov. Plate XLIII, Pig. 4. Pedioscertetes nevadensis , Ext. Pub. in Proc. Acad. Nat. Sci. Phila., by permission. The tip of the vertex is separated from the portion between the eyes by a shallow, curved, transverse sulcus, which runs from the upper canthus of one eye to that of the other ; the portion in front of the eye not quite as 868 ZOOLOGY— INSECTS. long as the eye, acute-angled, flat or very slightly convex above. Frontal costa prominent and narrow between the eyes and slightly sulcate, fading suddenly below the ocellus or broadly expanding and becoming obsolete ; lateral carinse indistinct and subparallel. Eyes oblong-ovate, subreniform, oblique. Antennae large, filiform, slightly depressed, and extending to the second abdominal segment ( 9 ). Pronotum subselliform ; front lobes rounded and subcylindrical ; the pos- terior lobe distinctly tricarinate ; sides flat and slightly expanding posteriorly; posterior portion of the dorsum slightly elevated ; the intercostal spaces flat, but slightly raised at the median carina ; the median carina is but an indis- tinct line ; the three transverse impressions distinct, but not profound, the posterior one placed slightly behind the middle ; the posterior margin reg- ularly rounded, nearly semi-circular ; the posterior lateral margin curves inward at tne humerus, but makes no angle ; the posterior lobe is distinctly broader than the head. Elytra of moderate width ; lower (anterior) mar- gin slightly arcuate ; wings rather narrow ; both extend slightly beyond the abdomen. The abdomen comparatively enlarged and rather deep at the base ; the valves of the ovipositor slender and acute. The body and legs hairy. Color (after immersion in alcohol). — Dull greenish-yellow, showing clearly that the original color was green, probably light pea-green, as the closely allied species Acrolophitus hirtipes. This appears to have been the uniform color of the insect, the elytra being unspotted ; there is a slight rufous tinge on the posterior part of the pronotum and base of the elytra ; the apical portion of the latter is translucent. Wings pale yellow at the base, probably a transparent greenish-yellow when living; a moderately broad fuscous band across the disk ; apex transparent, with dark nerves. Spines of the posterior tibiae very slightly or not at all tipped with black. 9. — Length, 1.25 inches; elytra, 0.80 inch; posterior femora, 0.60 inch ; posterior tibiae, 0.68 inch ; pronotum, 0.25 inch. Remarks. — This very interesting species, so far as I am aware, has been found in no collections except those made by this expedition. I find it marked as from Nevada, and, as it has been seen by no other collectors, I presume it must have been taken in the extreme southwestern limit of the ORTHOPTERA— ACRIDIDAE— SYRBULA LEUCOCERA. 869 second expedition. It is evidently closely allied to the Acrolopliitus hirtipes, Say, although the elevated pronotal crest and acute posterior pronotal margin of the latter place the two in different genera. Professor Cope has somewhere remarked that specific characters may be carried over from one genus to another. If he is correct in this opinion, this would appear to be a case in point, for the similarity in the specific characters of this species and A. hirtipes is apparent to the most superficial observer. The figure of this species is copied from one engraved by Pro- fessor Glover. By permission of Lieutenant Wheeler, a description of this new genus and species was published in the Proceedings of the Academy of Natural Sciences of Philadelphia, from which it was copied into my Synopsis. As it was given there really as an extract from this paper, it is given here as new. SYRBULA. This is another of Stiffs new genera in which he places a new North American species. I insert his short description of the genus. Similar to Mermiria, except as follows : — Antennae slender, filiform, slightly dilated toward the apex ; eyes longer than the portion of the cheeks below them ; prosternum destitute of a spine ; posterior lobe of the pronotum strongly punctate, rugulose.

Very similar to the S. montezmna, green changing into testaceous gray ; the cheeks and lateral lobes of the pronotum obscure fuscous ; an oblique vitta of the cheeks, margin of the mandibles, the entire broad exterior margin, and a narrow abbreviated interior margin and two abbreviated longitudinal lines of the lateral lobes of the pronotum pale. Elytra griseo- hyaline, sprinkled with fuscous ; veins reddish or fusco-ferruginous ; an anterior intercostal, ferruginous, opaque vitta. Posterior femora with tln-ee exterior fuscous spots ; posterior tibiae fuscous at the base, with a broad 870 ZOOLOGY— INSECTS. pale ring near the base. Wings very slightly fuscous. Genital segment elongate, acuminate ; cerci slender, but not acute. millimeters. Hab. — Colorado (Mr. James Ridings); foothills and plains of Colo- rado, end of September (Lieutenant Carpenter); Fort Garland, Colo., June 27 ; South Montana and Yellowstone (Mr. C. Thomas). This is the species given in my last report (p. 726) doubtfully as G. colubrinus. This interesting species is very near 0. colubrinus in the appendages and genital . parts of the male, but different in the pattern of color on the head and abdo- men, and the structure of the occiput in both sexes. 0. colubrinus is a spe- cies rarely to be found in collections; even the female is not yet described.

One larva of this genus from the Colorado Chiquito, collected in 1873 by H. W. Henshaw. The larva differs from those of C. cornuta by a larger prothorax, luteous legs, and the mark of the head. There are now six species known from Texas and New Mexico; of course, it is still impossible to ascertain the spe- cies of the larva from Colorado, but probably it may belong to one of the three Texan species (U. S. Geol. Surv. Terr., 1873, 579, 600). Note. — This specimen was inadvertently attributed to Professor Hay- den’s collection in the work quoted above. RAPHIDIA. The genus Raphidia belongs to the interesting class of genera which are represented largely in Europe and Asia, are entirely wanting in the fauna of North America east of the Rocky Mountains, but are represented again in California and in the other vast tracts of land west of the Rocky Mountains. I have seen only two specimens, one from Ogden, Utah (C. Thomas), the other from Rio Grande, Colorado, June 13 (collected by this expedition). Both belong to different species, and to Raphidia proper (not to Inocellia ). Both being preserved in alcohol, I am not able to give any better information, the more so as the genus Raphidia contains the most difficult species for determination (U. S. Geol. Surv. Terr., 1873, 600). 922 ZOOLOGY— INSECTS. MYRMELEON. MYRMELEON INSCRIPTUS, Hagen. Myrmeleon inscriptus, Hagen, Syn., 230, 11. A number of individuals supposed to be of this species were secured at Taos, N. Mex., San Ildefonso, N. Mex., Pagosa, Colo., Pueblo, Colo., by Dr. H. C. Yarrow and C. E. Aiken. They were in such bad condition, how- ever, as to render a positive identification impossible. PHRYGANINA. Some specimens belonging to this genus were secured by Dr. J. T Rothrock at Twin Lakes, Colorado, in 1873, and may possibly beP. atripes. They were, however, in such bad condition as to render a careful study almost impossible. In addition, some specimens of Limnophilus were obtained, also in a damaged condition. ERRATA. Reptiles and Batrachians.
