FBEPARED FOR THE SMITHSONIAN INSTITUTION BY JOHN L. LECONTE, M.D. J 1 PART I. WASHINGTON: SMITHSONIAN INSTITUTION: MARCH, 1863.-APRIL, I860. ADVERTISE ME XT. The following work is intcndocl as a companion to the " List of the Coleoptera of North America," by Dr. LeConte, It contains the descriptions of the new species named by him in Part I of the " List," which embraces the families treated of in Part I of the Classification of the Coleoptera of North America. The three works having been thus brought to the same point, it is the intention of Dr. LeConte to complete the series as soon as practicable. Pages 1— 00 were published in March, 18G3; pp. 87— 108 in April, 1800. JOSEPH HENRY, Secretary S. I. BjirrnsoNiAN Institption, Washington, April, 1866. Phtiadei.phia: oollinb, fkintbr. DESGRIl'TIONS OF NEW SPECIES. CICINDELA LiNS. I.

Long. '45. Mas palporum maxillarium articulo 2ndo apice pallido. Metby Portage, Hudson's Bay Territory ; Mr. R. Kennicott. This species belongs to the same group with C. repanda, &c., but differs from all the species known to rae by the markings. The white lines are all very broad, and arranged as follows : the humeral lunule commences at the base, extends along the margin, and then runs obliquely inwards, sometimes so as to touch the angle of the middle band ; behind the lunule is a white margin, which extends to the tip, obtusely dilated near the tip, where it represents the apical lunule ; the middle band arises perpendicu- larly from the white margin, bends backM'ards at an obtuse angle, runs obliquely nearly to the suture, and ends opposite the dilatation of the white margin ; the hind part of the band is straight and gradually clavate. The elytra of the two sexes do not differ ia form. In one specimen the marginal line is interrupted in front of the apical lunule, which thus becomes isolated. ELAPHRIJS Fabr. 3. E. OliTaceus.

Long. "27. Catskill Mountains, New York ; Mr. Ulke. Resembles in form and appearance E. politus and E. Itevigatus, but differs from both by the color, as well as by the line golden punctures which cover the head, thorax, margin and tip of the elytra, and also by the more dense punctures of the breast. BLETHI8A Bok. 3. B. jlllii. Supra uigio-senea cupreo-tincta, thorace punctato, latitu- dine breviore, lateribus rotundatis, angulis posticis obtusis subcarinatis, medio siibljevi, linea dorsali baud profunda, basi utrinque iuipresso, margine lateral! latiusculo reflexo, elytris tborace latioribus, oblongis, seriatim punctatis, interstitiis 3io et !)to latioribua foveis majusculia interruptis ; subtus nigra. Long. '45 — •47. Xova Scotia ; Mr. Ulke. The interruption of the 3d and 5tli intervals produce a catenated appearance : there are five foveae on the 3d, and three on the 5th interval ; the 7th interval is more elevated than the adjoining ones, but not interrupted. I take great pleasure in dedicating this beautiful species to my accomplished friend, Mr. Julius Ulke, whose labors in the field with his brother, Henry Ulke, have produced much advantage to science. DIACHILA MoTscn. 4> D.

Long. '33. Nova Scotia ; Mr. Ulke. Also related to L. semipnnctata, but differs by the thorax being more transverse, and by the hind angles being more obtuse and almost rounded. NEBRIA Latr. T. N. lllldsonica. Nigra nitida, thorace latitudine duplo breviore, postice anguatato, lateribua marginatia antice rotundatia, postice oblique sinuatis, angulia anticia rotundatia, poaticia rectia vix prominulis, linea doraali profunda, basi profunde, antice modice impreaao, elytria oblongia, striia punctulatis, interatitio Bio quadripunctato. Long. '41. Saskatchewan, Hudson's Bay Territory. Closely resembles JV. moesta Lee, but differs by the sides of the thorax being less sinu- ate, with the hind angles less prominent. 8. N. rildis* Aeneo-nigra, nitida, thorace latitudine sesqui breviore, postice paulo anguatato, lateribua marginatia antice rotundatia, postice subainuatia, angulia poaticia rectia, apice et basi punctato, et profunde iuipresao, linea doraali hand profunda ; elytria striia vage foveatis et interrnptia, interstitiis paulo convexia, 3io foveis 4 vel 5, 5to unica uotatis. Long. '44. Methy, Mr, Kennicott : one specimen. Resembles in form N. Eschscholtzii, but differs by the striae of the elytra being interrupted and having large but not deep punctures; the thorax is also less narrowed behind, and less sinuate on the sides. mm 4 DESCRIPTIONS OP NEW SPECIES. A specimen from Washington Territory, in Mr. Ulke's collec- tion, resembles the one described above, except that the sides of the thorax behind are still more feebly sinuate. I am unwilling, at present, to consider it as indicating another species. CYCHRIJ§ Fabr. 9. C. Tiolaceus. Saturate violaceus, thorace latitudine hand bre- viore, postice oblique angustato, lateribus late reflexo-marginatis, elytris ventricosis, anguste marginatls, latitudine sesqui longioribus, striis con- fertis punctatis. Long. '10. Mountains of Georgia. This species at first sight resembles C. andrewsii, but is immediately distinguished by the thorax being more broadly margined, and by the elytra being more rounded. It resembles in miniature G. viduus, but the margin of the elytra, especially towards the base, is not so strongly reflexed, and the antennae are more elongated ; it seems to be the last term in the series of forms by which C. unicolor is related to O. andrewsii. DYSCH1RIV8 Bon. 10. D. hispidus. Aeneo-niger nitidus, clypeo emarginato bldentato, fronte transversim impressa, thorace latitudine breviore, ovato, elytris convexis striis antice grosse punctatis, postice obliteratis, interstitiis alternis punctis setiferis ininutis uniseriatis notatis, an tennis pedibusque testaceis, tibiis anticis dente inferiore acuto, superioreque obsoletissimo armatis. Long. •12. Western States ; Mr. Ulke. Of the same size and shape as D. setosus, but differs by the inner striae of the elytra being distinctly impressed, and by the punctures being still larger.

Long. '25 — '30. Nebraska; Mr. Ulke. Of the same size and form as L. atri- ventrts; as in that species, the first three joints of the anterior tarsi of the male are obliquely dilated. The raetasternura in one specimen is dark, in another rufo-testaceous. 14. L.. loblllata. Pallide testacea, capite nigro, parce punctato, tho- race nigro, latitudine paulo breviore, postice paulo angustato, angulis posticis subrectis, rnargine lateral! pallido, elytris modice striatis, uigris limbo lateral! angusto, macula magna lobata humerali, apiceque late pallidis. Long. '12 — •15. Ohio and Louisiana; Mr. Ulke. Resembles at first sight L. axillaris, but the humeral spot, instead of being simply triangular as in that species, is lobed, with the inner and posterior outlines eraarginate, resembling some of the varieties of L. fuscata. The head is also distinctly though sparsely punctured, as in L. pul- chella, while in L. axillaris it is smooth. PLOCHIOSrUS Dej. 15. P. valeilS.

Long. •47. Nebraska; Mr. TJlke. This speciec. is related to P. adoxus, but differs from that as from all our otb»r species having no dorsal punctures, by the obtuse and rounded hind angles of the thorax ; in form it is narrower than P. adoxus, and resembles on a large scale P. longicoUis. The tip of the prosternum is not surrounded by a marginal line. 31. P. laetulus. I propose this name for the species form- erly described by me (Journ. Acad. Nat. So. 2d Ser. ii. 253), as Pv^ecUus californicus, from which it dififcrs by the bright green color, and by the sides of the thorax being distinctly sinuated behind, and also by the elytra being flatter and more finely striate. Baron Chaudoir considers this species as that described by Dejeao, but I have received from Count Mnizech, a species which corres- ponds in color and in other characters with Dejean*s description, and which is quite different as will be seen by the comparison above given. 32.

Long. '33. Louisiana; Mr. Ulke. This species is more nearly allied to P. ohscurus and ventralia than to any other of our native species ; it has like them but five striae on each elytron, and the scutellar stria is absent ; the 2d dorsal puncture is situated on the 2d stria as usual. It differs from the two species above named by the hind anglea of the thorax being distinct and not at all rounded, but this is not sufficient to separate it from them as a distiuct division of the genus. 12 DESCRIPTIONS OF NEW SPECIES. 3'y.

This species resembles to a remarkable degree Anisodactylus ellipticus, but is less convex and less shining ; the first joint of the front tarsi is longer than the two following, which are equal in size, and about twice their width ; the terminal spur of the anterior tibiae is broken, but is evidently dilated into a large tooth on the outer side, but whether there is a corresponding tooth on the inner margin I cannot determine. The first joint of the front tarsi does not extend under the second as in G. harpaloides. The last named species has a very extensive range ; a female was collected by Mr. Kennicott, on the Ked River of the North, and a male was given me by Dr. Schaum, as found in Louisiana ; the latter can in no respect be separated from Anisodactylus ; the middle and front tarsi are broadly dilated, and covered with a dense brush of hairs beneath, and the first joint is much narrower than the others ; the terminal spur of the front tibiae is tricuspid.

I take pleasure in correcting an error I formerly committed in considering this spe- cies as indicating a new genus of Colydiini, to which I gave the name of Pleuridium. The hind coxae are widely separated, and although the general form of body is that of Colydiini, the genus must be placed, as has been properly done by Erichson, in Both- riderini. It differs, however, remarkably from Bothrideres, not only in the form of body, but by the anterior coxae being con- tiguous, and by the first joint of the tarsi being very long. The structure of the buccal cavity is also very different from Bothri- DESCRIPTIONS OP NEW SPECIES. 69 deres, and similar to that of Colydium, the meiitura not being placed on a broad pedicel, and suddenly deflexed into a deep cavity as in Bothrideres.

The genus has the form and general characters of Telmatophilus, but diflTers by the 9th joint of the antennae being as wide as the 10th, thus forming a distinct three-jointed club ; in Telmatophi- lus the 9th joint is but little wider than the 8th, so that the club becomes more elongate than in Loberus. The elytral striae also afford a good distinguishing mark between the two genera. ANTHEROPHAOUS Latb. 366.

Agrees in coloration with P. discoideus, but the dark spot of the elytra in the male is so large that only a narrow basal sutural lateral and apical margin remains yellow : in the female the spot is not well defined in front. The punctures of the elytra are larger and less dense ; but the best distinguish- ing character is in the form of the first joint of the antennae, which in P. discoideus is prolonged and nearly acute at the tip, but broadly rounded in the present species. The male (as in the European species) is only distinguished from the female by the antennae being longer and stouter : no vestige of the double series of slender appendages observed in the male of P. discoideus is seen. m HELODES Latr. 319.

The sculpture of the thorax is peculiar; it is distinctly and tolerably densely punctured at the sides and before the middle, with a very finely punctulate broad transverHC space extending from the middle to the base, and from the dorsal carina to the depressed sides. The genus Pleotomus was established by me upon this insect, (Class. Col. N. America, 184,) without giving a specific description. It is easily distinguished from other genera of Lamjryrini by the antennae being 14-joiuted, about two-thirds the length of the thorax, with uie Ist joint short, obconical ; the 2d scarcely visible; the 3d to the 13th prolonged externally and internally, so that the an- tennae become bipectinate ; the 14th longer than the processes of the preccc'rig joint. The maxillary palpi are dilated, with the last joint securiform ; the labial with the last joint elongated, oval, somewhat pointed. The eyes are very largt , and very nearly approximated on the under surface of the head, behind the mouth. The 7th ventral segment is broadly truncate, or sub- emarginate, permitting the small conical 8th joint to become visible. The luminous segments (if any) are not distinguishable, owing perhaps to the general pale color of the insect. The pygidium is semicircular. The last joint of the tarsi is longer than the preceding. This genus seems allied to Laviprocera Lap., but differs by the greater number of the joints of the antennae, and the greater length of the last joint of the tarsi. MICROPHOTUS Lkc. Antennae short and stout, scarcely longer than the head, 2d joint nearly equal to the 1st, about as long as wide ; 3d joint very little longer, nar- rower at the base; 4th-9th gradually diminishing in length; 10th oval, not longer than the preceding; 11th very small, cylindrical, truncate and subulate, as in Phausis. Eyes immensely large, almost contiguous ; max- illary palpi with the joints broader than lo)ig, last one triangular, nearly acute. Prothorax semicircular, convex at the middle, widely flattened and impressed each side ; finely scabrous, without hyaline spots. Elytra suddenly widened behind the base, rounded at the sides and concave beneath the humeral elevation, gradually narrowed from the middle, tips rounded and slightly dehiscent. Abdomen with the last ventral segment prolonged at the middle and rounded at the tip in all the specimens 1 have seen ; last dorsal segment subtruncate. Wings perfect. Feet feeble, com- pressed ; first and second joints of tarsi somewhat longer ; 4th joint short, scarcely lobed ; 5th joint slender, as long as the two preceding united. ir 'is I', 1^ Vi" *■■* i ■^ IMAGE EVALUATION TEST TARGET (MT-3) V' ^ ^ f/ % •^" ,^ < >' Hiotographic Sciences Corporation 33 WEST MAIN STRUT WSBSTER.N.Y 14510 (716) •73-4503 ^'••'^^ i\ ^ ■w^ mM '/j 1 A m o \ l! 90 DESCRIPTIONS OF NEW SPECIES. A very distinct genus, not only by the form of the antennae but by the 4th tarsal joint being not lobed. It agrees with Phausis in the latter character, as well as in the last joint of the antennae being small and acicular; but differs by the antennae having one joint less, and by the thorax being destitute of hyaline spots. The under surface of the body is testaceous, so that I cannot ascertain the number of luminous ventral segments, but believe them to be two, as in Phausis. 335* "SH* dilatatllB* Elongato-ovalis, thorace pallido medio fasco, confertim scabro-punctato, medio vage canaliculate, et obsolete carinato, el]rtris fuscis, vage rugose punctatis, pone basin dilatatis, costa humerali acuta postice sensim obliterata ; subtus testaceus, ocnlis mazimis nigris, antennis fuscis.

Long. '08. One specimen, collected at "Washington, D. C, and given me by Baron R. Osten Sacken. This is the smallest species of the family Cleridae known to me. It is quite diflFerent from G. san- guineus Say, by the coarser punctures of the head and thorax, as well as by the narrower form, which is similar to Priocera, or Tarsostenus. The anterior tarsi are somewhat dilated, while the posterior ones are narrow, without distinct membranous lobes ; I therefore consider it as belonging to the division TJianeroclerus Spin., although it differs from that as from all other species of Glerus by the hind angles of the thorax being distinct, though obtuse. The ungues are quite simple. The lateral serration of the thorax is produced by the punctures upon a very obsolete margin ; the sides of the prothorax beneath are coarsely punctured, with a smooth shining space near the coxffi : I do not observe more than four joints in the hind tarsi, neither a short basal one, nor a small fourth joint being visible. More favorable examination of other specimens may indicate the DESCRIPTIONS OF NEW SPECIES. 9t propriety of placing it as a new genus, near Tarsostenus ; the antenuaj have the last three joints slightly enlarged and more approximate than in Clerus sanguineus. The last joint of the labial palpi is very large and dilated ; the maxillary palpi cannot be seen. HYDNOCERA Newman. 341. O. gullfasciata.

The large punctures of the elytra form eight discoidal and one marginal series, and there is a scutellar stria composed of three or four punctures. The epistoma is trilobed as strongly as in Triorophus, the middle lobe being angulated at tip as in that genus : the mentum is more flat than in Triorophus, being hex- agonal, and transverse, with the lateral angles distinct, and the front margin feebly emarginate ; but the difference in this respect is neither obvious nor important.

The mentum is very distinctly emarginate in front, the emargination being filled by the ligula, which becomes quite prominent. This species thus seems to indicate a diflferent group in the genus. In every other respect it agrees with typical Eurymetopon, except that the epistoma is broadly truncate at the middle, and very slightly sinuate each side, instead of being slightly emarginate in front, and rounded each side.* EMMEWASTUS Motsch.

There are no supraorbital ridges as in Triorophus, separated from the eye, but there is the small acute fold in front of the eye, which disappears at its upper margin ; the same fold is obs'.rved in Triphalus, Trimytis, and Emmenastus, but is wanting in Epitragus and Schop-nicus. t I have applied this generic name to several species, which, while being closely related to Eurymetopon, differ in the characters pointed out by Lacordaire, Gen. V, 66 ; viz. : a shorter mesosternum, epistoma rounded in front, and especially the anterior tibise truncate at tip, not dilated, with the outer angle not prolonged. The mentum is somewhat emarginate in front, and the ligula rarely visible. Mannerheim, (Bull. Moso. 1853, 112,) states that E. rugosus Motsch., the type of the genus, is only a specimen of Blapstinus pulverulentns ; but whatever may be the label, this view is not consistent with the generic description of Motschulsky, upon which I have based the reference of the species above described. It seems to me proper, therefore, while rejecting E. rugosus Motsch. as a doubtful, or im- perfectly described species, to retain the generic name for the species to which it will apply.

The antennae are shorter than the head and thorax, and the 9th r-nd 10th joints are somewhat broader than their length; the 11th joint is conical, and a little broader than its length. The under surface is slightly shining, rather strongly but not densely granulated ; the prosternum is very feebly prominent behind. This species differs from all the others known to me by the thorax not being margined at the sides : the punctures extend upon the sides so as to render the outline erenulate. Y 8S9. K. planipennis.

Long. -64. New Mexico ; collected by Mr. Fendler. Easily distinguished by the more depressed form ; the sculpture of the elytra consists of fine punctures, not arranged in rows: they are not closely placed, and become, as usual, converted into granules at the tip and sides ; they gradually disappear on the inflexed portion, which is more suddenly and more strongly inflexed than in the other species of the group. The species of Eleodes of small size, with unarmed femora, and ^ DESCRIPTIONS OP NEW SPECIES. 117 confused elytral sculpture, have the middle lobe of the rr>entuui brooder and the lateral lobes less distinct than in the other groups of species : the miadle lobe is broadly rounded in front, and in the present species is slightly transverse, with the lateral lobes small, inflexed, and scarcely visible ; thus approaching the new genus Discogenia, in which they disappear entirely. E. clavk'ornis makes an exception to the other small species, which requires it to be separated as a distinct group : the middle lobe of the mentum is prominent, elevated, and triangular as in the larger species of the genus. 9I8COOENIA Lec. Eleodes scabricula Lec, and marginata Esch., differ from the other species which have been referred to the genus, by the mentum be'ng quite flat, not at all trilobed, but transverse, widened from the base to the middle, then rounded, both at the front and sides, the lateral angles being also rounded at tip ; the surface is punctured, and is foveate each side near the lateral angle. The thorax is broader than long, much rounded and finely margined at the sides, with the hind angles not prominent ; it is feebly emarginate in front, with the front angles nearly obtuse. The elytra are oval, not wider than the prothorax, pointed behind, considerably rounded on the sides, and without humeral angles, so that they are more distant from the prothorax than in any species of Eleodes. The front thighs are unarmed, in the female, slightly angulated beneath in the males ; the tarsi are alike in both sexes. But two species named above are known to me. I regard E. Jischeri Mannh. as a large and well developed form of E. marginata. BI.AP8TI1VVS Waterhousb. 390.

A widely diflFused and not uncommon species, having the upper surface nearly as finely punctured as Cistela sericea, from which it is at once distinguished by the more broadly triangular, sub- cultriform last joint of the maxillary palpi. It is with some hesitation that I refer this species to Isomira, the outer side of the last joint of the maxillary palpi being in /. antennata twice as long as the apical side, while in our species the difference in length is not very great. I do not observe a complete uniformity in the form of the part in question in those genera of which I have examined several species, and therefore cannot consider the difference as sufficient to warrant me in pro- posing a new generic name. In one specimen, from New York, the inner side of the last joint of the maxillary palpi is distinctly bisinuate, but I observe no other character, except that the head and thorax are black, and the elytra paler and more finely punctulate than in the other specimens ; I have mentioned it in the List as /. veluiina.

The tip of the man- dibles is simple, slightly rounded, and not emarginate ; the last joint of the maxillary palpi is elongate triangular, with the apical and basal sides equal, the outer lobe of the maxillae is elongate with parallel sides ; the antenMae are slender, about one-half the length of the body, with the 3d joint a little shorter than the 4th. The lateral margin of the prothorax reaches the tip ; the anterior coxse are separated by the prosternura. The tarsi are simple, not longer than the tibiae, and the ungues have from 6-8 teeth ; the posterior portion of the hind coxae is slightly convex, and does not terminate in a sharp edge. The 6th ventral segment is slightly visible, and the 5th is marked with a transverse oval ex- cavation near the tip. Tl"* epipleurae extend nearly to the tip. The family Cistelidae seeras to need a thorough revision, in order that by comparing the species from different countries the limits of the genera may be properly defined, and their systematic relations recognized. m ^:i 8TATIRA Latb. 431. 8.

It differs generically in the form of the last joint of the maxillary palpi, which is neither broadly securiform as in Eurygenius, nor elongate and cultriform as in Stereopalpus, but subtriangular, elongate, with the apical and basal sides nearly equal, and the inner angle very obtuse ; the antennae differ from those of the two genera named by the last joint being much elongated, as in Statira, in the two specimens before me equal in length to the four preceding united. The sculpture of the head and prothorax is peculiar, con.sisting of slightly elevated umbilicated granules. The e^'cs, as in Stereo- palpus, are subtruncate and scarcely emarginate in front, and the claws scarcely dilated at base.

On examining the species of SorapHa in my collection, I find the differences in the maxillary palpi and hind tarsi are such as to indicate three genera, as follows : The last joint of the labial palpi in all three is very transverse, with the apical side longer than the others, and the prosternal sutures are not distinct. Last joint of maxillary palpi triangular ; Penultimate joint of all the tarsi lobed. Penultimate joint of hind tarsi not lobed. Last joint of maxillary palpi elongate, onltriform. scraptia. Allopoda. Canifa. To the first genua belongs Orchesia sericea Mels, The an- tennae are about two-thirds as long as the body, not very slender, with the 3d joint but slightly longer than the 2d, and the two united are not longer than the 4th. The last joint of the maxil- lary palpi is large, triangular, about one-half longer than wide, the outer side broadly curved, the apical and internal sides meet- ing at a right angle, which is quite considerably rounded, the inner or basal side about one-third shorter than the apical. The penultimate joint of all the tarsi is cordate, and somewhat lobed, and the first joint of the hind tarsi is twice as long as the others united in our species, and but little longer than the others united in the European S. fusca. To Allopoda belongs Scraptia lutea Hald., which I have, by the confusion of types sent to me, erroneously considered (Proc. Acad. Nat. Sci. VII, 219) as the same with S. pallipes Mels. The antennae are about half as long as the body, the 2d joint half as long as the 3d, which is not shorter tiian the 4th. The last joint of the maxillary palpi is about one-half longer than wide, Bubtriangular, with the internal angle more rounded than in the preceding genus, and the tip more acute. The penultimate joint of the front and middle tarsi is cordate, but that of the hind tarsi is slender, not at all dilated, and two-thirds the length of the preceding ; the first joint of the hind tarsi is shorter than the other three unite J. The third genus Canifa contains Scraptia plagiata Mels., S. jnisiUa Hald., and S. pallipes Mels. The antennae are a little more than half the length of the body ; the 2d and 3d joints are small, equal, and the 3d is as long as both united. The last joint of the maxillary palpi is cultriform, fully twice as long as its / f ■ DESCRIPTIONS OF NEW SPECIES. 145 width, with the apical side a little shorter than the outer side, aiid twice as long as the internal side which becomes basal, and meets the apical side almost at right angles. The penultimate joint of all the tarsi is cordate and somewhat lobcd, and the first joint of the hind tarsi is nearly twice as long as the others united. Allopoda may be distinguished from Anas^pia and its allies, which have similar maxillary palpi and hind tarsi, by the last joint of the labial palpi being transverse and securiform — the antennae not being thickened externally — by the anterior tro- chantin being distinct, and by the different form of the hind coxae, which do not conform to the ventral surface, but are raised from it.

The genus Dryala has not been adopted, because the type of it, Uallomenus fuscus, on examination by Schaum, Redten- bacher, and DuVal, was found to have the anterior coxae separated by the prosternum, as in the other species of HallomenuH. The anterior coxae, in the two species described below, are prominent, conical, and contiguous, their cavities have a very minute ex- ternal JSssure, and the lateral sutures of the prosternum are obliterated, in which respect it agrees with the genera of the tribe Scraptiini. The characters are therefore anomalous, and I am not certain that I have assigned to the genus the best position. In the Classification of North American Coleoptera I incor- rectly referred these two species to Trotomma, a European genus allied to Scraptia, and like it having the head strongly constricted behind the eyes forming a small neck, which is received into the prothorax. 444. j^. flaTiCOllis* Nigro-picea nitida, fortiter punctata, subtiliter pubescens, capite, thorace, autennia pedibusque ferrugiueis ; tljorace transverso, a basi antrorsum angustato, lateribus late lotundatis, apice truDcato, angulis anticis rotundatis, posticiii vix rotoudatis diinco postice utrinque vage oblique impresso, basi subainuata vix subtiliter margi- nata ; elytris thorace pauIo latioribus.

GerstsBcker has described (Mon. Bhipiphoridum, 21) both sexes of M. dimidiata aa having the antonnn black with the base testaceous, and it is solely in deference to this observation that I have described the two species in this note.

The penultimate ventral seigment in the male of L. niitlalli is broadly emarginate as in the present species, but the hind trochanters are armed with an acute spine, which in the female becomes a prominent angle. In L. cyanipennis the hind trochanters are similarly armed, but the penultimate ventral segment is acutely emarginato.

In C. angustus the thorax is feebly campanulate, the sides being rounded near the apex, and then broadly sinuate to the base. The pubescence of the elytra is uniform in the latter, while in G. aspersus longer hairs are intermixed.

Long. '22 — -SU. Abundant at Cape San Lucas, Lower California ; collected by Mr. Xantus. This species is somewhat robust iu form, resembling Oxacis dorsalis. It varies much in color, being sometimes entirely fuscous, sometimes testaceous, but usually the thorax is varied with spots and the elytra are marked with a broad discoidal vitta, and a shorter one near the scutellum. I observe no sexual differ- ences. LACCOBTOTVS Leg. 479. Li> punctatus.

Long. '11. Lec. Class. Col. N. America, 255. One specimen, given by the Rev. D. Ziegler, as found in York County, Pa. The generic characters are sufficiently detailed in the work above cited. I will merely add that, although the head is not prolonged into a beak, I have associated this genus with Mycterus on account of the small size of the middle coxro, the dilatation of the penultimate tarsal joint, and the absence of the lateral suture of the prothorax. The short 1st ventral segment is a singular character, not found in Mycterus, nor in any of the neighboring families ; the 2d ventral is nearly as long as the two following united, and is tumid at the middle with the anterior outline convex forwards ; a large pale yellow spot occupies the whole of the middle portion ; the 5th ventral is not shorter than the 4th, and is rounded at tip. I regard this genus a connecting form from Mycterus to Pythidae, though the full development of its relationships must depend on the discovery of other specimens. lil 168 PESCBIPTIONS OP NEW SPECIES.

Long. '65. One specimen from Canada. The head is more finely punctured than in P. niger and americanus, and the thorax is much more elevated and dilated upon the sides, with the hind angles quite conspicuous ; the discoidal impressions are deeper, and the two portions of each impression are more distinctly defined. The elytra are as finely punctulate as in F. americanus. SALFINGUiS Oyli. 450. S. ti1)ialis.
