 PART I. CONTAINING THE CERAMBYCI.

 In the present essay I have made many innovations in the former arrangements of 
 these insects. These will be found more obvious in the first group, the Lepturidae. 
 The indistinct characters of the genera as left by Serville and Mulsant, have long 
 rendered some other classification necessary ; since being founded on very slight and 
 arbitary differences of form, they unite together many species which, agreeing in 
 certain trivial circumstances, differ widely in general appearance. Such is the genus 
 Pachyta, which on account of its heterogeneous nature I have been compelled to 
 suppress altogether. Such again is Gmmmoptera, which was established on Lepturce 
 with linear elytra. If a comparison of a large number of species be made, this 
 character is found to be entirely fallacious, so that however clear the mathematical 
 distinction may be between lines that are and are not parallel, it will be seen that in 
 nature this distinction cannot obtain. The proportions and form of the elytra vary 
 in all the genera, and it would be quite as rational to separate into distinct genera, 
 those with incised and those with dehiscent elytra. 
 
 Although these characters are thus shown to bo mere specific marks, we may • 
 derive much aid from them in forming sections in those genera which contain many 
 species; they may thus be made to alleviate the labor of identifying species: and in

 the following pages have been made to contribute greatly to this very desirable object. 
 Indeed, the genera Leptiira and Strangalia might perhaps have been merged together, 
 since they only differ in the degree of prominence of the posterior thoracic angles; 
 this character is found to be variable, so that I have great doubt of its generic value. 
 
 Whilst thus exposing the faults of the heretofore arrangements of this group, it is 
 by no means presumed that the present scheme is unobjectionable. All that is 
 claimed for it is, that it is more applicable to American species, as well as those 
 European species which commonly occur in collections. 
 
 The large increase of genera may be objected to, no less than eight new ones 
 having been added to the Leptura alone, but these are recognized at once by certain 
 peculiarities of habitus, and the characters on which they are founded are, so far as I 
 know, invariable. The generic table appended to these remarks will render this 
 sufficiently obvious. 
 
 There does not appear to be much accurate parallelism between the European and 
 American species of this family ; and most of the genera found in Europe are equally 
 developed on this continent. An exception to this principle is found in Rhagium, of 
 of which we have but a single species. Vesperus and Rhamnusium are peculiar to 
 the old continent, but here Desmocerus represents the former and Ceniroderus the 
 latter. Peculiar to America are Piodes, Gaurotes, and Typocerus, the five other new 
 genera are distributed over both continents. There are two species of this group 
 which are indigenous to Europe and America, viz ; Acmceops strigilata and Strangalia 
 sexmaculata: they are confined to the Northern regions neither of them occurring 
 south of Lake Superior. 
 
 The genus Distenia will be found among the Cerambycida. I know not why it 
 has been associated with the Lepturce, viilh. which its affinity is very slight: it is 
 much more closely allied to Eburia and Cerasphorus. 
 
 Before passing to the specific details of this tribe, it may be proper to say a few 
 words on the characters which distinguish the LepturcB from other sections of the 
 Longicornia, and to ascertain the true value of the division which they form. 
 
 Longicornia have been divided by Latreille, Serville, and other authors, into three 
 groups, Prionidce, Cerambycidce, and Lepturidce. The first group distinguished by 
 the deflexed labrum, rudimentary inner-maxillary lobe, and the antennie inserted in 
 front of the eyes. The second group has the head not narrowed into a neck and the 
 antennae are placed between the eyes. The third is separated on the single character 
 of the head being narrowed posteriorly into a kind of neck. The second group is 
 again divided into two: Cerambycini, with porrected head and dilated palpi, and 
 and Lamiarii, with deflected head and piliform palpi. 
 
 This arrangement is very unsatisfactory, since by following it, we associate with 
 Priorii, Asemum, Criocephalus, and other genera, which in form are true Callidia ; 
 
OF AMERICA NORTH OF MEXICO. 
 
 313 
 
 while Dislenia, although strongly resembling Cerasphorus, put among Leplurce. 
 Again, there are many true Cerambyci, (e. g. Ilenopterus,) which have the head 
 elongate and porrected : Necydalis likewise has the head suddenly contracted behind 
 precisely like Toxotus, while the front is deflected and the palpi filiform; so that it 
 becomes difficult to determine whether the genus belongs to the Leptum, Ceramby ci 
 or Lamice. 
 
 So fallacious are the received characters, that a genuine Saperda-ioxm. with 
 abbreviated elytra, has been described both by Newman and Haldeman as a 
 Molorckus, {Thia, Nm., Tessaropa, Hald.) and another genus {Encylops, Nm.) allied 
 to Necydalis, has been placed near Toxotus. A new genus from Georgia has a 
 remarkable resemblance to Dorcadioti, whilst the head is prolonged behind the eyes, 
 and its true affinity is with the gibbous Clyti. It is thus plainly seen that these 
 divisions so distinct in nature, have not yet any natural distinctions in our systems. 
 
 Dr. Zimmerman has recently recognized the importance of a character heretofore 
 neglected, and through his kindness I am enabled to make use of it in the present 
 essay. He finds that in all Laniia-ioxm&, the anterior tibi® have an oblique .sulcus 
 internally, which in many cases becomes so deep as to form an emargination, such as 
 IS observed in most Carabica. This character, with a single exception, is wanting in 
 all other Longicornia. Making use of it and at the same time suppressing the 
 primary group Lepturce, as not possessing sufficiently distinct characters, we obtain 
 three great divisions which embrace all Longicornia.

 Having now laid the ground work of a classification, we may proceed to investigate 
 the relations existing between the different groups which have thus been obtained. 
 
 The Lamia* meet the Ceramhyci in several points, Dorcadion tending towards 
 Clytus, while Saperda unites with Necydalis; some tropical forms tend towards 
 Doi'cacerus. 
 
 The Prioni meet the Ceramhyci in two points. Pyrodes approaches Megaderus and 
 Tragosoma, Asemum : they then lead to the Lamellicornia in Lucanus. The Leptura 
 branch of the Ceramhyci is related to the PhijtopJiaga by Acmceops, which approaches 
 Donacia. Piodes is a very anomalous form which seems closely allied to the Prioni, 
 but I am inclined to believe it more nearly related to Megamerus Kingii, (McLeay) 
 among the Phylophaga, which is said to have the same coriaceous structure as the 
 Prionus and Piodes. On the other side, this branch is closely connected with the 
 Ceramhyci by Necydalis, so that no character can be used to separate them, excepting 
 the conical coxae. The Spondylns branch is related to the typical Ceramhyci, through 
 Asemum and Callidium: this form attains its highest development in Hypocephalus, 
 which is another isolated form connected only with the contents of its own group. 
 
 The very peculiar appearance of the Spondylidoe might lead many to consider it as 
 of equal value with that which is observed in the Lamia or Prioni, separating them 
 by their short and robust legs, with dilated and dentated anterior tibiae. Now, 
 although these species differ in this respect from the typical Ceramhyci, yet on 
 comparing several together, great differences are found in these same organs. 
 Hypocephalus has only a few large teeth on the tibiae, Spondylis huprestoides a fine 
 serration, while Scaphinus {Prionusmuticus, Fabr., Spondylis spharicollis, Lee.) has a 
 large expansion at the end of each tibia. The antennae of Spondylis are at the base 
 of the mandibles as in Prionus, but on examining the Callidia a gradual transition 
 will be found between this position and the one assumed in the typical Ceramhyci. 
 The relations ju.st pointed out, as far as they can be exhibited on a plane surface, are 
 shown in the following diagram. 
 
 •Tins group is to be considered as the highest form of the Longicorn beetles; since with perfection of 
 organisation, it is entirely free from all complicated relations. Its affinities are only with other Longicornia, and 
 with only one section of them ; and this isolation must always be a property of the highest division of any group, 
 no matter what its extent may be, since the highest form is that in which some typical idea attains its maximum 
 of development. We find in every group a highest form, in which, to use a physical symbol, the branch 
 terminates, and in every case the comparative value of this branch may bo ascertained by tracing its connection 
 with others; that which soonest assumes a distinct form will bo the highest.

 from the next group by the position of the antennae, which are either in front of the

 The form of the head varies in this genus. In some species the sides are parallel

 head appears narrowed behind those organs, ( T. cinnamopterus.) The character that 
 especially distinguishes this genus, is the position of the terminal spurs of the tibise, 
 which, instead of being apical, are situated at the upper end of a deep oblique 
 incisure.

 This genus is very close to the preceding, and only differs in the structure of the 
 antennae. These organs in the male are rather thick, with the sixth and following 
 joints compressed. Carinated on the edge, with a denuded granulated elliptical 
 impression of each side; the eleventh joint is constricted in the middle and furnished 
 with two pairs of impressions. In the female the antennae are less compressed, the 
 side not carinated, the impressions are smaller than in the male, those on the external 
 surface being sometimes scarcely visible. The body is arched, and narrowed at each 
 end.

 The male is narrower and shaped like L. chrysocoma. This species with the next 
 constitutes Dejean’s genus Trigonarthris. They only differ from other Leptura in 
 having the intermediate tarsi as broad and as short as the anterior pair. They are, 
 however, more dilated in the males, and, moreover, are not alike in all Leptura: for 
 these reasons I have thought it more natural to replace these species among the 
 genuine Leptura.
