IL—Catalogue of Coleoptera of the Regions adjacent to the Boundary Line between the United States and Mexico. oO By Joun L. LeConts, M. D. Since the time when the entomological productions of Kansas were made known to science by Thomas Say, no expedition under the direction of government has so largely contributed to a correct knowledge of the insect fauna of Western North America as the United States and Mexican Boundery Survey. * Not only have large numbers of new genera and species been added to science, but the limits of many previously known species have been ascertained, and new points _ fixed for the final solution of the intricate problems of geographical distribution. Many of the new species added to our fauna vie with the most splendid productions of the tropics, while others by their curious forms are in strong contrast with the usually dull and ordinary appearance of the Coleoptera of the United States. As the collections were made in a continuous belt of country extending from the Gulf of Mexico to the Pacific Ocean, they serve well to illustrate the remarkable changes in fauna, dependent on longitude: an element, on this continent, of much greater importance than latitude in determining the distribution of organized beings. *This catalogue is the preliminary portion of a report on the Coleopterous insects collected by the U.S. and Mexican Boundary Commission, which was prepared at the request of the Commissioner ; after its pre- paration, involving a labor of fifteen months, was completed, information was given me that its publication had not been provided for, and recently the MS. has been returned to me, with a letter from the Hon. Secretary of the Interior, in which occurs the following passage : “Its publication in the second vol. of the Report of Major Emory is inadmissible from the fact that Major Emory appears not to have contemplated it in his corres- pondence with this Department, previous to his turning over the work, and his departure for the West. In his letter of October 7th, 1857, he says, ‘The second vol. is composed of Zoology and Botany, Prof. Baird writes the Zoology, and Dr. Engelmann writes the section on Botany relating to Cactacew, Dr. Torrey writes the remainder of the Botany.” The points worthy of the attention of the scientific student here presented are two-fold: 1st, that the Com- missioner should not have contemplated in his correspondence with the Department the publication of material that he had already requested to have prepared for the Report: 2nd, the exclusion by the Commissioner of Entomology from Zoology, by the statement that “ Prof. Baird writes the Zoology,” when the facts were that only the Vertebrata were undertaken by my learned scientific friend. T do not desire to be understood as attaching blame to any person in this matter, but make this statement for the purpose of accounting for my own apparent idleness in science for a period. T also take occasion here to return my grateful acknowledgements to the Hon. J. Thompson, Secretary of of the Interior, for the use of the lithographic plate prepared to illustrate the Report. i) D [From Journ, Acad. Nat. Sci., Vol. IV. No. 1, Noy., 1858. ] 10 LE CONTE.—COLEOPETERA OF THE Near the Pacific coast, that is to say, as far east as the Sierra of California, another element of a more directly evident character, may be noted in connection with the same subject: it is the effect of the Arctic current which sweeps along the Californian coast, and equalizes the climate of the maritime portion of the State. On the crest of the Sierra this effect ceases, and the influence of the cold current is combated by the continental climate, which gives a region of extreme dryness during the whole year, with great ranges of temperature, in different portions of the day and year. This region, broken only by a few fertile mountain valleys in its eastern part, extends from » the Californian sierra to the Rio Grande, when in the gentle descent to the Gulf of Mexico the climate again becomes more equable, assuming, however, the subtropical character belonging to its latitude. We accordingly find thatin Texas a large proportion of the Coleoptera are identical with those found both at New York and New Orleans, the difference of latitude being accompanied with but moderate variation; others are tropical species found in the adjoining portions of Mexico, and some again represent sparingly the group of Tene- brionidee which play such an important part in the insect fauna of the regions farther west. Among genera not belonging to these categories must be noted Lutrochus, which here makes its first appearance in North America: the other species are found in South America, in Brazil. The manner in which the catalogue of species is made, obviates the necessity of forming statistical tables of distribution, but I have placed at the end of the present remarks some abstracts, which will be found of interest to the general student. It therefore remains for me only to note specially the collections from which the materials used in the present investigation have been obtained; they are briefly as follows : 1. Collections made by Mr. J. D.Clark, in Texas, near the Rio Grande, at Frontera, and at San Antonio. 2. Extensive collections made by Mr. Arthur Schott at Eagle Pass, Texas, and on the journey from Laredo to Ringgold Barracks. 3. A fine series collected by Mr. Weise, on the journey last named. 4. Very thorough collections made by Mr. Horace Haldeman in various portions of Texas. 5. A small, but valuable set, collected at New Braunfels, a and purchased from Mr. Lindheimer. 6. Large collections made by Dr. Thos. H. Webb in the region between the Rio Grande and Colorado River of California, chiefly in the valley of the Gila. 7. A considerable collection made by Mr. Schott in the region last acquired by purchase from Mexico, and now called Arizona. 8. A collection of considerable size made by Capt. Pope, while Plesne Llano Hstacado and the upper Rio Grande. 345 ; (Si Zein Insags ™~ y APid 8 S51, pi NSE Nation wes Z UNITED STATES AND MEXICAN BOUNDARY. 11 9. Large collections made by myself, in 1850-51, between San Diego, California, and Fort Yuma on the Colorado River. An excursion from the latter point to Tucson furnished but small results, as the season was unfavorable, and subsequent loss of transportation required my attention to be directed from science, to objects of more vital importance. Notwithstanding the copious materials here brought together, the region reported on must furnish still important results to future collectors. Every collection that has yet been made, has furnished a very large proportion of new species, and with few exceptions the same species have not occurred at different places or times. The minute ones, except in the region visited by myself, have received but little attention : an immense number yet remain. Exception has been made in the Catalogue of six or seven Curculionids: of which the genera could not be determined, and of many Staphylinide, which should not be described, until a monograph of all the species found in the United States be prepared. Several species of Heterocerus are also allowed for the present to remain unnamed. Various species which have recently been procured, or which have remained undis- cribed are added in order to bring the catalogue fully up tothe present time.

Of these Callisthenes is found in the central portion of the continent, though not extending to the proper maritime Atlantic region. It will be observed that many of these genera just mentioned are subarctic forms, and may be expected to occur hereafter in Labrador. The genus Ergates must be also received with caution into this list, as the same species is ranked in the British Museum Catalogue under Macrotoma, a genus of much more extensive distribution. We have then remaining of genera as yet known only in the temperate zone, found on the western slopes of the two continents, but absent from the Atlantic slope of America, only Anillus, Rosalia, Mesosa and Timarcha.

The only exceptions thus far are: Haplochile, Thalpius, Axinopalpus, Epiphanis, Perothops, Asaphes, Melanactes, Desmocerus. DESCRIPTION OF NEW SPECIES. Harpalus impotens, piceo-niger, oblongus, thorace transverso, lateribus rotundatis, margine angusto reflexo, angulis posticis rotundatis, basi utrinque vage foveato, versus angulos subdepresso, elytris ad marginem subtiliter pubescentibus, striatis, striis 2, 5, 7 parce punctatis, interstitiis fere planis, epi- pleuris ano pedibusque piceis, antennis palpisque rufo-piceis. Long. -38. A specimen found at El Paso by Dr. T. H. Webb, of the Boundary Commission. This species is narrower than H. (Selenophorus) stigmosus, and iripennis, and readily recognized by the rounded angles of the thorax, and the smaller elytral punctures. Pasimachus validus, niger nitidus, margine vix cyanescente, mandibulis rugosis, thorace transverso postice angustato, lateribus anguste marginatis ad basin sinuatis, angulis posticis rectis; elytris ovatis postice acutis, lateribus parum rotundatis, humeris obtusis (preecipue distinctis) subrotundatis, et breviter carinatis, dorso convexis, antice preecipue depressiusculis, seepe seriatim punctulatis, (seriebus per paria approximatis ;) tarsis posticis tibiis haud longioribus. ong. 1:12—1-43. Tab. IV. fig. 10. Pasimachus punctulatust Lee. Ann. Lyc. Nat. Hist. New York, 4, 146; tab. 7, fig. 3. Kansas, Texas, Arizona; abundant. Having a numerous series of specimens before me, I am led to believe that the characters of this species are by no means constant, and it seems probable that the form of the elytra must be disregarded, and the very short humeral carina, and the comparative length of the posterior tarsi be considered alone as diagnostic. In this case the next species will appear as only an individual variety, although the differences in form are such that I can hardly believe it possible. The posterior tibize, on the inner surface below the middle, are in the male densely, in the female sparsely clothed with erect hairs. On account of this character, and its general resemblance to P. depressus, I was formerly led to believe this to be P. punctulatus Hald., but the type of that species has since been kindly pre- sented to me, and on comparison I find them quite distinct ; the humeral carina of P. punctulatus is longer and the margin is distinctly blue; it in fact differs from UNITED STATES AND MEXICAN BOUNDARY. 15 P. depressus only by the mandibles and labrum being deeply rugous, and by the pos- terior tarsi being not longer than the tibie, while the latter in the male are densely pubescent on the inner surface. P. corpulentus, niger nitidus, margine vix cyanescente, mandibulis vix rugosis, thorace transverso, postice angustato, lateribus postice breviter sinuatis, angulis posticis rectis, elytris rotundato-ovatis postice subacutis, lateribus valde rotundatis, humeris haud distinctis breviter carinatis, dorso equaliter convexis, seriatim punctulatis (seriebus per paria approximatis); tarsis posticis tibiis haud longioribus. Long. 1-15. Laredo to Ringgold Barracks, Texas, Mr. Weise; Sonora, Mr. Schott. Only differs from P. validus by the characters mentioned; and eventually perhaps to be con- sidered as a race of that species. P. costifer, niger nitidus, margine vix cyanescente, mandibulis rugosis, thorace transverso, postice angustato, lateribus rotundatis ad basin brevissime sinuatis, angulis posticis parvis rectis, elytris ovali- bus antice subtruncatis, postice subacutis, lateribus late rotundatis, humeris haud distinctis carina mediocri, dorso equaliter conyexis, seepissime seriatim punctulatis, (striis per paria approximatis, inter- stitiis saepe alternatim parum elevatis) versus marginem uni- vel bicostatis; tarsis posticis tibiis haud longioribus.

The sculpture of the elytra is very variable, but all transitions are found in the series before me, between those with one and those with two coste, those with smooth elytra, and those with punctures in rows approximated by pairs, with the wider spaces more or less elevated. One specimen, (‘97 long.) in default of more information may be forthe present placed here; it was collected by Dr. Webb in Arizona. The elytra are without any trace of costee; the body is of a more slender form, being nearly asin P. elongatus Lec., but it differs from that species by the humeral carina being shorter, and making with the lateral margin an acute angle, while in P. elongatus the angle is rounded by the carina bending outwards so as to make a curve with the lateral margin. Although differing so much I think it more prudent to allow it to remain as a variety of P. costifer, until more specimens occur. Plate IV. fig. lla represents an elytron. P. obsoletus Lec., is nearly allied to P. costifer, but the imner intervals be- tween the rows of punctures are more distinctly elevated, and the rows are single. Agabus obsoletus, ellipticus, parum convexus zneo-niger, nitidus, conspicue reticulato-strigosus, thorace lateribus obliquis late rotundatis, cum elytrorum lateribus angulum haud formantibus, antennis pedibusque anterioribus piceo-rufis. Long. -33. One male found at San Diego; differs from any other Californian species by its elliptical body and scarcely perceptibly reticulate surface: the shape is nearly that of A. punctulatus Aubé, but the sides of the thorax are less rounded, and conse- quently the approach to an elliptical form is nearer. 16 LE CONTE.—COLEOPTERA OF THE Aleochara valida, atra, capite thorace elytrisque opacis, profunde subtilius punctatis, pube brevi hispida indutis, thorace transverso rotundato, antice late subemarginato; elytris thorace haud longioribus, abdomine nitido parcius punctato, lateribus pilosello, ano sanguineo, antennis nigris pilosellis. Long. -19—37. Tab. LV. fig. 16. San Diego, California, under decomposing Opuntia stems. Of a dull black color, above finely granulate, without lustre except on the abdomen. Head sparsely punctured, thinly clothed with short suberect hair, obtusely pointed anteriorly, eyes oblong, not prominent ; antennze as long as the head and thorax, third joint a little longer than the second, fourth only half the length of the third, 5—10 transverse, gradually a little broader, sparsely pilose with verticillate hairs, llth longer and narrower than the preceding, conical, obtusely rounded at tip. Thorax a little broader than long, transversely slightly convex, anteriorly broadly emarginate, sides and base curved with a circular outline, anterior angles rounded, slightly deflexed, finely not densely punctured, covered with short erect black hair. Elytra shorter than the thorax, punctured and hairy like it, flattened, truncate with the outer angle rectangular and rounded. Abdomen above shining, sparsely pubescent and punctured, parallel on the sides, obtusely rounded at the tip; anterior segments transversely impressed and smooth towards the base; sides strongly reflexed, pilose with longer black hairs: anus sanguineous. Body beneath densely punctured and pubescent with blackish brown hair. Varies much in size, but usually larger than any other species of the genus and having a peculiar habit. I was at first inclined to regard it as a new genus, but after a patient examination and dissection I failed to find any character by which it might be separated. Canthon vigilans, rotundato-ovalis, parum convexus, ater opacus vix zenescens, clypeo subtilius granulatos antice bidentato, sinubus ocularibus latiusculis; thorace lateribus angulatis, margine ante medium, inferne interrupto, et tuberculo minuto preedito; clytris obsolete striatis; fossulis pedum anticorum distinctis. Long. -67—-85. Texas, Georgia, Missouri: Precisely like C. le vis, and chalcites in general appearance. ‘The granulation of the surface is finer than in the first, but much coarser than in the second; and it differs from both species by the greater breadth of the por- tion of the eye which is seen in the clypeus. Cremastochilus saucius, rufo-castaneus, nitidus, thorace transverso, angulis anticis auriculatis, posticis incisis et retrorsum acuminato-productis, disco ad angulos anticos breviter, intra posticos longe exarato, parte mediana zequaliter subtilius punctata, lateralibus incrassatis, convexis leevibus, extrorsum punctatis ; elytris punctis elongatis sat densis insculptis ; pygidio punctato, subcarinato : mento parum concavo, margine postico subangulato, haud inciso. Long. -42. Lodge Pole Creek, (Nebraska,) Mr. W. Wood; Llano Estacado, Capt. Pope. Readily known by the remarkable form of the thorax, the surface of which is divided into three lobes by the meeting of the long posterior, and the short anterior excavations, UNITED STATES AND MEXICAN BOUNDARY. 17 which commence immediately at the respective angles. It belongs with the other Western species to the division Psilocnemis Burm. C. squamulosus, piceo-niger confertim punctatus, punctis squamulis pallidis minutis notatis, thorace lateribus subangulatis, angulis anticis mammillaribus, haud prominulis, fovea magna interna rotandata signatis, angulis posticis parvis rectis sulco circumdatis, dorso subcanaliculato, ad basin depresso ; mento valde concavo, postice anguste inciso. Long. -40. Florida, Baron R. Osten Sacken. Nearest in appearance to C. canaliculatus, but smaller, with the fovea at the anterior angles of the thorax larger, and the punc- tures smaller. The scales of the punctures both on the thorax and elytra readily distinguish it. The incision of the mentum is narrow. THRINCOPYGE Lec. T. alacris, elongato-oblonga, late viridi-zenea nitida, capite grosse rugose punctato, fronte inaurata, thorace latitudine breviore antrorsum latiore, et transversim valde convexo, angulis anticis rotundatis, lateribus subrectis, basi utrinque recta obliqua, angulis posticis obtusis, parce subtiliter punctato, ante basin transversim impresso, margine laterali guttisque ad apicem pluribus lecte flavis; elytris fortiter marginatis, lateribus subsinuatis, postice oblique angustatis, ad apicem truncatis, striato-punctatis, striis postice exaratis, interstitiis levibus, macula antice transversa in marginem ad humerum extensa, altera majore ad medium, tertiaque postica elongata leete flavis ; coxis posticis macula flava ornatis. Long. :8. Variat elytrorum maculis plus minus deficientibus, antica seepe divisa. One specimen, Arizona, Mr. Schott. Numerous specimens from New Mexico were brought by Capt. Pope. Congeneric with Buprestis ambiens Lec., and having somewhat the form of Agrilus, though apparently related to Ancylochira. Antenne shining, joints 3—6 successively wider, 7—11 triangular, with pores on the inferior edge. The labrum is small; the antennz distant, inserted in small foveze; the mandibles carinated, acute; the mentum closely united to the ligula, transverse, truncate, convex, entirely corneous. The sterna are not sulcate, mesosternum divided for only half its length. Legs unarmed, tarsi with broad equal joints, fifth depressed with widely divergent ungues. Scutellum small triangular. The fifth ventral segment of the abdomen is marked with a deep marginal groove around its posterior half; the groove each side ends suddenly in a small yellow spot. I cannot refer these species to any previously described genus. Telephorus planicollis, fusco-niger, tenuiter parce pubescens, capite ante oculos pallido, thorace pallido, vitta dorsali fusca, latitudine fere duplo breviore, parum convexo, levi subinzequali undique anguste marginato, elytris thorace haud latioribus minus subtiliter scabris. Long. -33. One specimen, May 29th, Capt. Pope. Belongs to my division a. (Proc. Acad. 9, 340,) the outer claw of the posterior tarsi being armed with a large tooth : the thorax is comparatively less convex than usual, and the discoidal impressions are very vague : the reflexed margin is narrow, and equal at the sides, at the apex and the base; the 2nd joint of the antennz is one third the size of the first or third which are equal. The head and thorax are pale beneath, but the legs and trunk are entirely black. ~ ) 18 LE CONTE.—COLEOPTERA OF THE Trichodes bibalteatus, elongatus, rufo-pilosus, supra dilute rubidus, capite thoraceque longius villosis, clytris grosse confertim punctatis, fascia ante medium alteraque latiore ad dodrantem nigris ; subtus niger antennis rufis clava fusca. Long. -63. One specimen, Texas, Mr. Ulke. Related to T. apivorus, but narrower, and with no apical black spot on the elytra ; the hair is also different in color, being reddish, while in T. apivorus it is black. Microschatia sulcipenuis, ovalis, convexa, atra opaca, thorace parce punctato antrorsum angustato, lateribus rotundatis marginatis, ad basin late rotundato utrinque sinuato, angulis posticis paulo productis subrectis, elytris sutura costisque utrinque 5 elevatis, 1ma 3iaque postice confluentibus 2nda 4taque utrinque abbreviatis, hac cum 3ia postice connexa, sulcis punctis quadratis magnis cribratis. Long. -60. One specimen, Llano Estacado, Capt. Pope. The mentum is large, leaving be- tween its sides and the mandibles only room for the palpi; the antenne are stout, with the last joint very small, and the tarsi are thick, thus agreeing in generic characters with M.inzqualis. The prosternum is also broad and slightly produced as in that species. The abdomen is sparsely and not coarsely punctured. Purtoitaus Lac. In advance of the publication of the fifth volume of his work on the genera of Coleoptera, Prof. Lacordaire has sent me his description of the characters of this new genus, which contains all the species described by me as Pelecyphorus. Though agreeing with that genus in the form of the mentum, which leaves a free space each side, more than sufficient for the movement of the palpi, it differs in the anterior tibie not being produced into a spine at the outer apical angle. Such at least is the only distinct difference noted in Prof. Lacordaire’s description, and the only one that I have found in comparing specimens of Pelecyphorus mexicanus /Sol., kindly sent me by Mr. Sallé. An unnamed Mexican species, related by form and sculpture to P. mexicanus, also sent me by Mr. Sallé, does not show any trace of this spine, while in P. confluens, hirsutus, and especially in P. rimatus, this spine, or rather prolonga- tion of the apical angle is quite distinct. Under these circumstances, though I have adopted the genus proposed by my learned friend, I am greatly in doubt whether it will not be necessary to recombine it again with Pelecyphorus, the species of which being numerous and very different in form, may be divided into several natural groups, according to the form of the antenne and tarsi, and the sculpture of the elytra. The table of the relation of genera of Asidites, as sent me by Prof. Lacordaire is as follows: I. Antenne 11-articulate ; maxille rarely visible. a. Anterior tibiz cylindrical : the apical external angle not prominent. b. Mandibles separated from the submentum by a distinct interval. Base of elytra emarginate in the are of a cirele Microschatias UNITED STATES AND MEXICAN BOUNDARY. 19 Base of elytra truncate or sinuate Philolithus. 6b. Mandibles and submentum contiguous Ologlyptus (Stenorides.) aa. Anterior tibie compressed with the apical external angle prominent. Posterior angles of thorax distinct. Pelecyphorus, Asida. Posterior angles not distinct Huschides. II. Antenne 10-articulate: maxille visible in part. Tibize compressed, dentate Cardigenius. Tibiz rounded, mutic Scotinus. Taking the division with 1l-articulate antenne, it appears to me that a more natural relation between our native genera is expressed as follows: A. Mentum filling the emargination of the gula. a. Last joint of maxillary palpi moderately dilated : mentum and mandibles approximate, leaving room only for the palpi. Base of elytra truncate, inflexed portion broad. Prosternum prominent, outer apical angle of anterior tibie prolonged Astrotus Lee. Prosternum not prominent, anterior tibie truncate Pactostoma Lec. Base of elytra emarginate, inflexed portion narrow Microschatia Sol. b. Last joint of maxillary palpi very large: mentum and mandibles separated by a moderately wide space : inflexed portion of the elytra wide Pelecyphorus Sol. B. A distinct fissure between the sides of the mentum and the gula: last joint of maxillary palpi very large: inflexed portion of elytra wide EKuschides Lee. The type of Astrotus is Microschatiacontorta Lec.; and of Pactostoma is Asidaanasto- mosis Say. Pelecyphorus eger, piceo-niger, subnitidus, thorace latitudine duplo breviore, antice posticeque angustato, lateribus valde rotundatis depressis transversim rugosis, disco parce punctato, ad basin late emarginato, angulis posticis subacutis, elytris ovatis convexis postice valde declivibus, sutura, costis dorsalibus duabus ante apicem confluentibus margineque elevatis obtusis interstitiis inzequalibus haud punctatis : subtus parce punctatus, epipleuris inequalibusimpunctatis. Long. -75. . Llano Estacado, Capt. Pope. Closely related to P. sordidus Jec., but differs by the disc of the thorax being only distantly punctured, while in that species the punctures are large, close and confluent. The under surface is likewise less densely punctured, and the epipleuree are almost entirely free from punctures. The cost of the elytra are broader and obtuse. Pelecyphorus irregularis, piceo niger nitidus, thorace latitudine plus duplo breviore, antice angustato, lateribus rotundatis depressis transversim rugosis, disco sat dense punctato, ad basin late vix emarginato, angulis posticis subacutis, elytris ovatis convexis postice valde declivibus, sutura costis duabus ante apicem confluentibus margineque elevatis, interstitiis valde inzequalibus, impunctatis ; subtus punctatus, epipleuris punctis paucis notatis. Long. -81. Llano Estacado, Capt. Pope. Also related to P. sordidus, but the sides of the thorax are less rounded, the base is hardly narrowed, and the disc is less densely, less coarsely and not confluently punctured. 20 LE CONTE.—COLEOPTERA OF THE Fa) Pelecyphorus costipennis, piceo-niger, sordidus, opacus, thorace latitudine plus duplo breviore, lateribus valde rotundatis depressis, undique dense grosse confluenter punctato, ad basin late emarginato angulis posticis’ productis acutis, elytris breviter ovatis-convexis, postice valde declivibus, sutura costis duabus ante apicem confluentibus margineque valde elevatis, interstitiis valde inzequalibus, epipleuris parce, punctatis, abdomine dense punctato.

Long. -44—-52. Arizona, Mr. Schott. Comparatively narrower than KE. dubius Lec., much larger, with less convex and scarcely punctured thorax, and more distinctly punctured elytra ; the latter exhibit a faint tendency to become sulcate, and the punctures are very obviously muricate: they are nearly parallel on the sides for three-fourths of their length, then narrowed obliquely to the apex which thus appears nearly acute. Embaphion contusum, atrum opacum, thorace latitudine fere duplo latiore, antice profunde emarginato, lateribus valde rotundatis, disco parum convexo, parce punctato, margine lato explanato modice reflexo, angulis anticis subacutis, posticis latis obtusis valde rotundatis, basi media recte truncata, elytris dorso planis, postice valde declivibus, et acute angustatis, thorace vix latioribus fortiter reflexo-marginatis seriatim subtilius sat dense muricato-punctatis, ad apicem singulatim breviter acuminatis ( 9 ) vel in cauda brevi prolongatis (€). Long. -65—-665. Fort Laramie and Santa Fe. Though differing very much in form from the Heleeus- like E. muricatum Say, the form of the antenne, oral organs and legs require it to be associated in the same genus with that species. Two specimens brought by Dr. Thos. H. Webb from Arizona differ in having the side of the thorax much more strongly reflexed, so that that part becomes con- siderably narrower than the elytra. This is probably merely an individual varia- tion, as similar differences occur in Cychrus elevatus, as in many other insects in which the margins of the body are widely reflexed.

Long. -35—-40. Three specimens agreeing in color, from Llano Estacado, Capt. Pope. Differs from our common, much varying species, called R. varicolor by Gerstaecker, (but which should rather be named R. pectinatus Fuabr., that being the earliest name given to the species,) but differs by the head being uniformly densely punctured, by the an- UNITED STATES AND MEXICAN BOUNDARY. 21 terior face of the occiput being a little flattened, and by the posterior margin being more broadly margined. R. bicolor Say, placed as a synonym to varicolor by Gerstecker, differs very much by the anterior face of the vertex being flattened, and the posterior so broadly rounded as to appear almost truncate, as noted by Say in his descriptions, Dr. Mel- sheimer considering the name bicolor as preoccupied by Olivier, substituted R. ambiguus, but described under that name a variety of R. pectinatus. Under these circumstances, in view of the fact that the name bicolor was preoccupied at the time of the description by Say, I have changed the name to R. Sayi, and although more recently Gersteecker has placed Olivier’s species as a synonym of R. bimaculatus, this does not obviate the necessity of removing the name which was imposed by Say under a misapprehension. KupompeuHa Lec.

Corpus alatum, elytris integris. A very singular genus related to Lytta and Phodaga Lec., but sufficiently distinct from the first by the entire eyes, placed obliquely and not transversely, and from the second by the tarsi not being spinose beneath. The form is long and slender as in Lytta polita Say. The anterior thighs are not sinuate beneath near the tip, and have no dense pubescence at that place.

Mas antennis ad articulo 2ndo geniculatis, palpis maxillaribus articulo ultimo magno elliptico, subtus concavo, patelliformi. One specimen, collected May 10th, by Capt. Pope, on the route to Llano Estacado. This species belongs with L. mylabrina, &€., to my division B—e, (Proc. Acad. 6, 331); and the male of the latter species, as I have recently ascertained possesses similar sexual characters, though the dilated last joint of the maxillary palpi is more ovate, and is not so concave beneath. I have not seen males of L. Germari, and do not know whether they are similarly provided. It is also to be noted that in the male of L. mylabrina, the antenne besides being suddenly geniculated between the first and second joints are less slender than in the female. Connected closely with L.mylabrina, are two forms to be here noticed; the first was collected by Capt. Pope on the Llano Estacado. It is -45—-55 long, sculptured, colored and spotted asin L.mylabrina, except that the lateral spots of the thorax are wanting, the two discoidal ones alone being present: the elytra are shining, less densely and more distinctly punctured. Sexual characters as above: first joint of the antennze usually testaceous, or spotted, rarely entirely black. The second form is found in Texas and New Mexico, was collected by Mr. Schott, and Capt. Pope. It is -7—-9 long, sculptured, colored and spotted, as in L. mylabrina, except that the elytra have only the two basal spots on each, and a large quadrate black blotch behind the middle extending from the suture almost to the margin, and corresponding to the medial transverse band of L.mylabrina; the apical black band is entirely wanting. The first joint of the antennz is testaceous. All these forms vary greatly in the color of the under surface, and seem to present the phenomenon of races, and lead to the conclusion that L. Engelm anni Lec., will eventually be ranked with them under L. mylabrina. Lytta vittigera, sordide rufa, capite thoraceque nitidis parce punctatis, hoc latitudine longiore, antrorsum sensim angustato, macula utrinque antica in latera, alteraque postica discoidali nigris, elytris dense subtiliter punctulatis, subtiliter 4-lincatis, vitta lata nigra a humero fere ad apicem extensa; subtus nigra suturis rufis, femoribus basin, trochanteribusque testaceis. Long. ‘82. Near the boundary of Texas. Dr. Berlandiére ; two females. Belongs to the same group as L. mylabrina, and probably varies equally in the size of the black spots of the under surface. One specimen, besides the black stripe of the elytra, has a black spot near the scutellum, but in the other it is hardly visible. It is nearly related to L. discoidea Lec., but is very much larger, and has the elytra much more densely UNITED STATES AND MEXICAN BOUNDARY, aS punctured, and the legs differently colored. In the species last mentioned the sexual characters are asin L. mylabrina, but less strongly developed: the dilated joint of the maxillary palpi is narrowed, slightly trapezoidal, and flattened beneath. Lytta tenella, nigro fusca, undique pube cinerea pruinosa, vix punctulata, capite antennis pedibusque rufo-testaceis, illo linea longitudinali glabro, thorace latitudine paulo longiore, campanulato, rufo- testaceo, ponnunquam nigricante. Long. -46. Llano Estacado, July 4th, Capt. Pope. Belongs to group B—g, with L. penn- sylvanica, maculata, &c., from all of which it differs much by the color. The outer spur of the anterior tibie is a little broader than the inner one, and obtuse. Lytta linearis, elongata nigra, pube cinerea densissime vestita thorace latitudine longiore subcam- panulato, labro vix emarginato, antennis articulis 2 et 3 brevibus (hoc tamen longiore) conjunctis 4to vix longioribus. Long. -46. One specimen, August 4th, Llano Hstacado, Capt. Pope. In form resembles our common L. Fabricii Lec., (cmerea|| Fabr.), but differs from it and from all others known to me by the proportion of the 2nd and 3rd joints of the antennz. The joints after the 4th are equal in length, moderately closely articulated, slightly diminishing in breadth: the 2nd and 35rd joints together are a little longer than the 4th, and the 3rd is a little longer than the 2nd: the first joint is a little longer than the 2nd and 3rd together. The spurs of the posterior tibie are slender and acute. For present convenience this species may be placed in B—g, near L. lemniscata. Lytta costata Lec., was also collected by Capt. Pope in considerabie numbers, and I am therefore enabled to note on the present occasion the sexual characters. In the male the first articulation of the antennze extends behind the eyes, and is slender; the 2nd is two-thirds as long as the Ist: the 3rd is double the length of the 2nd: the 4th and dth are similar to the 3rd; the remaining joints are equal, and individually only one-third the length of the oth. In the female the Ist and 3rd joints are equal, the 2nd less than two-thirds of the length; the 4th and 5th are equal to the 2nd, and the following ones about two-thirds the length of the 5th. I stated (Proc. 7, 84) that the species might enter group B—g, but the above mentioned sexual characters would seem to indicate the propriety of establishing another group B—g’. for its reception.

A genus distinguished rather by the want of any prominent character, and which will very likely fall into some previously established by other authors, but which from the imperfect method of description used cannot be identified with satisfaction. It belongs to the numerous group V. of my arrangement, (Journ. Acad. 2nd ser. 2, '7,) which is known by the round dehiscent anterior acetabula, acute mandibles, flat mesosternum, simple not clavate thighs, compressed palpi and very short front. The genera have been increased since the writing of my paper, and renewed investiga- tion having revealed some other characters, the following table, in advance of a full supplement to my memoir, may be found useful.

Long. *80—1°0. Llano Hstacado, Capt. Pope. Stouter than the other two species, and proportioned nearly as Purpuricenus: the hairs of the head and thorax are shorter, the lateral spine of the thorax much larger, and the elytra uniformly convex, not at all sulcate, The anterior tibise are sometimes testaceous at the base. The prominences between the antennee, even in the male, are less conspicuous than in the other species, and the first joint of the antennz is comparatively less thickened.

The antenne are thickened externally. | Tetraopes discoideus, niger, undique cinereo-pubescens et nigro-pilosus, thorace lateribus parum sinuatis, medio subito sed haud alte elevato, guttis 4 nigerrimis notato, apice et basi coccineo, elytris basi lateribus et ramo ad medium laterali obliquo coccineis, mox pone ramo macula utrinque niger- rima notatis; antennis nigris haud annulatis. Long. -32. Llano Hstacado, Capt. Pope. Remarkably distinct from all other species by the © black head. It is more nearly allied to T. umbonatus Lec. than any other, and its marking may be conceived to be derived from the design of that species by extending the black over the greater part of the thorax, and enlarging the anterior black blotch of the elytra so that it unites with the posterior one, as in some varieties of T. canteriator.

Long. °32—-47. Platte River, Nebraska: Llano Estacado, Capt. Pope. Related to D. trimacu- lata, but apart from the markings of the elytra, it differs by the sides of the thorax being nearly parallel posteriorly, so that the base is not at all narrowed as in that species. The spots on the elytra are variable in size, and the two middle ones are sometimes confluent. They are placed: on each, two small ones near the base, and UNITED STATES AND MEXICAN BOUNDARY, 27 a large humeral one; then two at the middle near the suture, sometimes confluent ; then three, the outer one near the margin, the inner ones usually confluent, and about one-third from the suture and one-third from the tip; finally a small dot near the lateral margin, about one-fifth from the tip; the suture is dark brown, nearly black. I dedicate this species to the memory of my iamented and highly esteemed friend W. F. Rogers, whose synopsis of the Chrysomelee of the U. 8. (Pr.

XXIIL.—Synopsis of the species of Prerosticuus Bon. and ,allied genera inhabiting temperate North America. By Joun L. LeConte, M. D. Although many attempts have been made to dismember the croup of Carabica here treated of, yet a close analysis of the genera formed has always shown them to be untenable, and most systematic authors now follow the example of Dejean and Erichson in uniting them into a single genus, by some called Feronia, by others Pterostichus. By those who regard purity in the system of nomenclature, as possessing some claims to importance, the latter name is adopted, as it has priority by several years. In regard to the grouping of the large number of species com- posing this genus, so as to facilitate our knowledge of them, very little has been attempted, and the older divisions, at least as defined by Dejean, or by the English authors, so far from being of service, only tend to mislead the student. Being now occupied in writing a synonymical catalogue of the Coleoptera of the United States, I have subjected all our species of Pterostichus to a critical examina- tion, the results of which I here offer, with the addition of diagnoses of all the species observed. The genera made by European authors, such as Platyderus, Argutor, Omaseus, Platysma, Adelosia, &c., I have entirely neglected, as I can find no definitions of them which are recognizable, and it is very doubtful, whether, being founded on merely slight differences in form of body, they should be considered as belonging to anything more than the particular European species, which were chosen as types. The only memoir that I have been able to refer to with any satisfaction, is that of Baron Chaudoir ;* and although, as will be seen in the sequel, I find it impossible to adopt the numerous genera founded by him, yet I cannot but consider his essay as the first rational attempt made to partition the species according to.their real affini- ties. a I have been able to separate distinctly only five genera from the genus as left by Dejean: Pacttus Bon.; Evartarus Lé. ; Loxanprus Lec: ; Lopnoctrossus Lec. F and Ho.tciopHorus Lec. oe 2s The second of these was already established by Chaudoir-upon a single species under the name Cyclotrachelus, which is totally inapplicable-to most of the species of theseenus as here set forth: as,.moreover, Baron Chaudoir would; probably refuse to * Bulletin Soc. Imp. Nat, de Moséou, 1838, Nox Ff. 57 226 LECONTE—SYNOPSIS OF PTEROSTICHUS. consider my group as constituting a single genus, corresponding with his Cyeclo- trachelus, I have felt myself compelled to adopt a new name, leaving to those who may wish still farther to divide the genus, the power of restoring Cyclotrachelus to the particular set of species for which it was intended. The third genus is precisely equivalent to Chaudoir’s genus Megalostylus,* which name was however previously employed by Schénherr for a genus of Curculionites. _ The two last genera, LopHociossus Lec. and HoiciopHorus Lec., have been sepa- rated on account of the structure of the ligula, which, instead of being flat, or slightly convex, as in the other genera of this group, is strongly carinate; as in the genera above referred to, these differences are accompanied by peculiar sexual structures in the male, so that throughout this group the males have much more generic character than the females, and it is indeed the permanency of these sexual characters through- out closely allied species that gives the first distinct clue towards a dismemberment of the group. In establishing the diagnoses of these genera, we are, however, compelled to neglect these sexual characters, as they are applicable to the males alone. But having once recognised by their aid the existence of natural genera, and having sketched out their limits, we may then make use of characters of less importance to define these genera. Thus I have been compelled to rely upon dorsal punctures for the generic character ; and although there is such a gradual transition from those with several dorsal punc- tures, to those with none at all, yet itis singular that those species with single dorsal punctures form well defined genera, not merging at all into the others, Our genera may be separated by the following synoptic table : A.

These genera form a little group in the family of the Pterostichini, distinguished by having the mentum strongly toothed, the tooth usually bifid and concave; the ligula truncate with linear paraglosse ; the palpi slender and cylindrical, the last joint truncate, never longer than the preceding, and usually a little shorter. ‘The anterior angles of the mentum are sometimes acute and sometimes rounded, but for systematic purposes, as little use can be made of them as of the angles of the thorax. ‘The pos- terior legs are sometimes close to the intermediate ones, and sometimes far removed. This character is constant throughout every genus, except Pterostichus, where there * Bulletin Soc. Imp. Nat. de Moscou 1842, p. 24. LECONTE—SYNOPSIS OF PTEROSTICHUS. 227 are transitional forms. ‘The posterior tibie are finely and sparsely ciliate with bristles and sometimes almost smooth in Evarthrus, Pterostichus, Lophoglossus and Holcio- phorus; they are strongly spinous in Loxandrus and Peecilus. The posterior and intermediate tarsi have on the outer margin two grooves with an intermediate ridge extending usually to the third joint. This is wanting in Evarthrus, Holciophorus, Lophoglossus and a few species of Pterostichus. The three first joints of the anterior tarsi of the male are dilated, and furnished beneath with a double series of papille; the dilated joints are oblique in Loxandrus; transverse and not emarginate in Evarthrus: obcordate, sometimes transverse, but more or less emarginate in the other genera. The intermediate tibie are emarginate near the apex on the inner surface and armed with two teeth in the males of Lopho- slossus. ‘The posterior tibie are serrate internally along their whole extent in Hol- ciophorus, and slightly curved inwards in Loxandrus. The last ventral segment is sculptured in various ways in the males of many Pterostichus and Holciophorus : it is simple in the others. There is but a single anal puncture each side in both sexes of Evarthrus, except in E. mancus, where the female has two: there are two in the females and one in the males of most Pterostichi: there are, however, two in both sexes of P. Isabelle and P. illustris. Evartueus Lec. Antenne articulis basalibus simplicibus: labrum vix emarginatum: ligula convexa, apice rotundata, subtruncata, paraglossis linearibus, eam paulo superantibus ; palpi articulo subcylindrico; parapleure breves ; elytra unipunctata, stria scutellari vel brevi, vel distincta; tarsi posteriores extus non sulcati; tarsi maris antici articulis tribus dilatatis triangularibus precipue transversis non emarginatis. Besides the characters given above, the first joint of the abdomen, except in the last species, is marked on each side with a deep transverse line, appearing like a suture. The anal punctures are single in each sex, except in the last species : the last ventral segment of the male is usually without impressions; in the first four species it has two faint impressions separated by a longitudinal elevation. In E. conviva, it has a single impression. In EK. mancus there is a small transverse tubercle near the apex. The dorsal puncture is always situated on the third stria just behind the middle. When by a monstrosity, the puncture becomes double, the second is always close to ‘the normal one. The pectus and venter are never punctured : all are without wings. According to the form of the thorax and position of the ninth stria of the elytra we may divide the species as follows: 1. Striis marginalibus valde approximatis, a.

The species of this group are somewhat oblong insects, usually of a dull black color, with little lustre. 'The thorax is quadrate, rounded on the sides, with the pos- terior angles obtuse, not rounded, and not prominent; the basal impression is very distinctly double, with a slight ridge at the margin; the posterior transverse impres- sion is so deep on each side as to appear like a third basal impression; the anterior transverse line is deep. The elytraare marked with entire but not deep striz, whicn are distinctly punctured ; the eighth and ninth are very closely approximated, being scarcely as far apart as the diameter of the ocellate punctures which are between them; the scutellar stria is usually an oblong point. ‘The last ventral segment of the males is widely impressed ; in the first four species this impression is divided by a longitudinal elevation, in E. conviva, it is single and undivided. 1.

These are species very similar in appearance to those in (b.) but usually of a more slender form, and with the thorax more rounded on the sides, and more constricted behind ; the posterior angles are always prominent, the basal impressions are usually large and deep, bistriate, and with a small ridge between the outer stria and the margin. The anterior transverse line is either entire or interrupted; the margin narrow, not reflexed; the strie of the elytra usually deep, the seventh rarely indis- tinct or obliterated ; the outer marginal stria distinct, not nearer to the inner one than to the margin. They are mostly western species, inhabiting the plains of Missouri Territory. 18.

A very numerous genus, and somewhat variable in generic characters, but which may be easily divided in natural groups, by taking into account those structures upon which specific characters are impressed. The variations in generic characters can scarcely be used for systematic division, since every imperceptible gradation occurs between those with short and those with lone epipleure; those with the tarsal grooves on the outer margin deep, and those with the same grooves nearly obsolete ; and also between those with a bifid tooth in the chin, and others in which the tooth is simply obtuse. The marginal stria (the 9th) is never approximated to the ocellate punctures. ‘The variations in the characters above referred to will be pointed out * LECONTE—SYNOPSIS OF PTEROSTICHUS. 235 under the particular groups in which they occur.

None of the species of this genus are found in North America; they may be divided into several groups, such as Abax, Molops, &c., according to the form of the thorax. Feronia quadricollis LeConte, An. Lyc, 4, 343, does indeed belong here, but it is no American insect, and is identical with Pterostichus parallelus of Europe. a. MWe have here a larve number of species, usually of a slender form, with the thorax quadrate and gradually narrowed behind ; the margin of the elytra is moderate and has but a single stria; the elytra have no dorsal punctures; the parapleure are short. For the better determination of the species, which are frequently very closely allied, this group may be subdivided : a. Thorace basi immarginato. Sp. 1—9. gs. Thorace margine basali medio interrupto. Sp. 10—15. 7. Thorace basi tota marginata. Sp. 16—17. a—a. The thorax is trapezoidal, narrowed behind, the posterior angles distinct, not promi- nent; the basal impression is linear and single except in the two first species in which there isa short outer impression, margined in the first by a very faint carina; the base is entirely without a marginal line. ‘The anterior tarsi of the males are variable e 236 LECONTE-—SYNOPSIS OF PTEROSTICHUS. in their form; the dilated joints are broad and almost transverse in the first two species, while in the others they are distinctly longer than wide; in both sexes of P. rostratus and P. grandiceps, the fourth joint is scarcely narrower than those which precede, and the last joint is much flattened and broader than in the other species. The grooves on the outer margin of the posterior tarsi are not deep. This group corresponds in part with Chaudoir’s genus Haploccelus. 1.

Although Dejean described Feronia Luczotu as apterous, yet this species agrees so perfectly in other respects that I am obliged to consider it the same. It is difficult to believe that species so closely related as P. Luczotii and the neighboring species would differ in such a particular, if it were a constant character, and I therefore conclude that Dejean’s observations were made on an imperfect individual. h. In these species the margin of the thorax is wider and more reflexed than in any of the preceding; it isa little narrowed behind; the posterior angles are obtuse, the basal impression is large and very deep, obsoletely bistriate, with a carina adjacent to the angle; the elytra are deeply striate and have normally but two dorsal punctures both in the second stria, one before, the other behind the middle; frequently specimens are found with three, or even four dorsal punctures, but a practised eye at once distinguishes the normal from the accidental points.

This genus only differs from Pterostichus in the form of the ligula, and I have some doubts whether it should really be separated; but in order to leave the limits of the preceding genus distinctly defined, it will be necessary to retain this as a generic eroup, since it has no trace of a groove on the outer margin of the four posterior tarsi. This genus in part corresponds to Chaudoir’s Lyperus. The three species below described correspond in the following particulars. The head is large, the eyes prominent. The thorax subtransverse, narrowed behind, a little rounded on the sides, which have a strongly reflexed margin gradually becoming wider behind ; anterior transverse line deep, distant from the margin; the basal angles obtuse, not rounded, the basal impressions deep and single; the elytra are flattened, little wider than the thorax, deeply striate, the strie a little less deep at the apex ; the margin is narrow, and the ninth stria is equidistant between the series of punctures and the margin; the humeral angles are distinct and rounded.

Mannerheim’s description is so short as to be obscure.

Very distinct by the absence of the anterior transverse line of the thorax, and the coarse punctures of the elytral strie, which are smooth only towards the apex. ‘The apex of the elytra, the epipleure and the abdomen, are piceous, but the specimen is probably a little immature; the iridescent reflections of the upper surface are very brilliant. PdiCILUS Bon. Antenne tenues, articulis 1—3 acute carinatis; palpi cylindrici, articulo ultimo vix breviore; mentum dente medio concayo, emarginato; ligula subplana, apice truncata, paraglossis eam paulo superantibus ; labrum vix emarginatum; mandibulz breves; parapleurze subelongatz ; elytra punctis dorsalibus, striaque scutellari notata; tarsi tenues, posteriores extus sulcati; antici maris articulis 3 obcordatis, duobus primis emarginatis. The carina on the basal joints of the antenne easily distinguish this genus; the posterior tibize are very spinous, as in Loxandrus, but the fourth joint of the tarsi is not sc small, so that the last joint is only as long as the two preceding.

One of the elytra is occasionally tripunctate, but the points are all behind the middle, so that one is evidently abnormal. Only two joints of the antenne are rufous, and I am therefore in doubt whether this is the same as Dejean’s | species, which has three rufous joints. I have never seen blue specimens. 3.

The law of priority is however inflexible, and Say’s name must fall before Pecilus chal- cites Germ. Ins. Noy. 15. The latter was published in 1824, while Say’s paper could not have been printed before 1825, the date upon the title page of the volume. It is a pity that a memoir made known to the American Philosophical Society as early as 1819 should thus yield to one five years posterior to it; but as I above observed, the law of priority is inflexible, and, except within a few years, authors haye been completely at the mercy of the slow moving bodies to whom they entrusted their labors. As a remedy against this feebleness of action, an idea was broached, in this city, and debated with considerable acrimony, that the date of reading before a learned society should be considered as the true date of publication. It is remarkable that such a scheme should ever be endorsed by any one claiming to have a regard for the purity of science, as it necessarily subjects the whole scientific world to a dozen or two individuals, too often unknown to science, and to many of whom the subject brought before them must be entirely without interest. ved LECONTE—SYNOPSIS OF PTEROSTICHUS. 255 Santa Isabel, California. ‘The punctures of the elytra seem very variable; in one specimen there are five on one side and four on the other; in a second there are two on one side and three on the other. b. 7.
