From the Proceedings of the American Philosophical Society, Feb. 1, 1878, and April 18, 1878. 1878.]_ 303 (Schwarz. The Coleoptera of Florida. By E. A. SCHWARz.* (Read before the American Philosophical Society, Feb. 1, 1878.) The following list is founded upon matcrial collected during two expe- ditions to Florida. In the spring of 1875 collections were made at Haul- over near the northern end of Indian River from February 23d to March 20th, at Ft. Capron, on the same lagoon about a hundred miles south of Haulover, from March 26th to April 28th, at Enterprise on the upper St. Johns River from May ‘7th to 28th, at Cedar Keys, on the gulf coast, from June 2d to 9th. In the following year collections were made at Tampa from March 24th to April 30th, and again at Enterprise from May 15th to June 27th. On both trips smaller collections were made at various points: Fernan- dina April 16th, Palatka February 13th, Sand Point on the Indian River February 19th to 22d, Lake Harney on the upper St. Johns River in the beginning of May, at Baldwin on the Jacksonville and Mobile R. R. on June ist and June 10th, Lake Ashby in Volusia County and New Smyrna in the beginning of June. A number of interesting species were also ob- tained on the journey across the peninsula from Tampa to Enterprise dur- _ ing the first half of May. As the localities where the most extensive collections were made differ greatly in character, and as no points in north-western Florida, nor at the southern extremity of the peninsula were visited, I must abstain from drawing any conclusions concerning the local distribution of Coleoptera in Florida. The sandy plains at Haulover, covered with scrub-oak and saw- palmetto, were not found elsewhere ; the ocean and lagoon beaches of the eastern shore, especially at Capron, are rich in peculiar forms, and as the Gulf Stream here flows only six or eight miles off the coast, it is quite possible that many of these species are direct importations brought in the West Indian seeds and drift-wood constantly being thrown upon this low and sandy coast. The Coleoptera from Enterprise represent the fauna of the ‘‘ hammocks,”’ a term applied in Florida to the dense hard-wood and palmetto forests, as distinguished from the open and sandy pine lands or cypress swamps. At Tampa special attention was paid to the fauna of the pine forests. In all districts covered with pine woods occur depressions, which in the dry sea- son become swampy meadows, with a fauna remarkably rich in species and in specimens, and nearly identical in character throughout the State. Notwithstanding the very uniform temperature during the entire year, the dry season, which corresponds with the winter months, causes a disappear- ance of insects in Florida almost as complete as in the north; in the beginning of March they appear suddenly with the first leaves of the oak, * With additional descriptions of new species by JOHN L.

The beginning of the rainy season about the end of May brings out the full summer fauna. Though far from complete, the following enumeration of species is judged sufficiently extensive to give a tolerably clear idea of the character of the Floridian fauna. I desire to express my indebtedness to Dr. LeConte, without whose aid in the determination of species, this list could not have been prepared. The following abbreviations for localities are used in the List of Species. A.—Lake Ashby. K.—Cedar Keys. B.—Baldwin. L.—Lake Harney. C.—Ft. Capron. N. 8.—New Smyrna. E.—Enterprise. P.—Palatka. F.—Fernandina. §.—Sand Point. H.—Haulover. T.—Tampa. *Species recorded from Florida not collected by myself. Descriptions of New Species. By E. A. ScHWARz. 1. Lebia rhodopus, n. sp.—Head and thorax greenish or bluish black, subopaque ; the former large, wider than the thorax, finely aluta- ceous, sparsely and obsoletely punctulate; antennze more than half the length of the body, outer joints stout, joint 3 and base of joint 4 testaceous ; palpi black. Thorax small, transverse, on the sides very little rounded and subsinuate before the hind angles, which are rectangular ; side margin less broadly reflexed than in Z. viridis ; finely. alutaceous, indistinctly trans- versely rugose or obsoletely punctulate. Elytra blue or greenish blue, shining, very finely alutaceous, striz finer and more obsolete than in Z. viridis, interstices subconvex. Beneath bluish black, legs, including the coxe, bright rufo-testaceous, tarsi blackish, claws pectinate. Length 4.5 mm. ; .17—.18 inch. Alhed to ZL. viridis and pumila; from the former distin- guished by its larger head, which as well as the thorax; is hardly shining, and by the color of antenne and legs ; from the latter by its larger size and the coloration of the upper side and of the legs; irom either species by the long and stout antenne. Two specimens from Tampa, found in April on. the blos- soms of Chameerops serrulata. 2. Apenes ansgustata, n. sp.—Shining, head and thorax metallic green, elytra dark coppery ; beneath black, antennz, palpi and legs testa- ceous. Head a little narrower than the thorax, longitudinally strigose, ~~ <)> =p 1878. | Ove (Schwarz. with some scattered punctures, clypeus alutaceous, minutely and sparsely punctulate. Thorax in front but little wider than long, at the sides less rounded and less narrowed behind than in A. lucidula ; hind angles indi- cated by an interruption of the reflexed margin, transversely rugulose and sparsely punctulate, near the front margin more evidently punctate, punc- tures sometimes confluent in longitudinal rugosities. Elytra of a dark coppery color with an oblong yellow spot at the base of the 6th interval, finely but deeply striate, striz distinctly punctulate, interstices flat, aluta- ceous, sparsely and obsoletely punctured. Length 9.25 mm.; .37 inch. Of the same size as A. lucidula, but narrower and with a different form of the thorax; the sculpture of head and thorax is finer, the elytra are darker colored with the scat- tered punctures on the interstices less evident. Enterprise; three specimens, apparently females. CYCLONOTUM. ! The four North American species before me may be dis- tinguished by the following table: I. Antenne with more or less solid club; prosternumi carinated in front, prolonged behind between the cox and almost reaching the meso- sternum ; first ventral segment carinate; elytra with distinctly im- pressed sutural strice at apex : Antennal club solid, prosternum very short in front of the coxe: metasternum in the middle slightly but abruptly raised in an ob- long shining plate, which is narrowed in front. Size small, rows Of punctures on the elytra very obsolete............... palmarum. Antennal club less solid, prosternum moderately long in front of the coxe, metasternum with an oblong, not elevated, not pubes- cent, opaque spot.

Antenne with a loosely jointed club of three joints, prosternum feebly prolonged between the -coxe ; metasternum strongly longitudinally carinated, carinashining, more or less punctulate, but not sharply limited laterally ; first ventral segment not carinated ; elytra without sutural stria. Larger, rounded-oval, elytra moderately densely punctulate, legs pice- ous black, tibiz distinctly punctulate..... Updos Sacr . estriatum. Smaller, rounded, almost hemispherical, elytra less densely punctu- late, legs stouter, piceous red, tibiz smooth......... semiglobosum. 8. Cyclonotum palmarum, 2n. sp.—Rounded-oval, convex, above black, shining, anterior part of head, sides of thorax and tip of ely - tra sometimes red, beneath red, metasternum darker in the middle, anten- nz, mouth and legs bright rufo-testaceous. Head very finely aciculate and Schwarz. ] 356 [Feb. 1, obsoletely remotely punctulate, antennz with the first joint elongated, but much less so than in (@. cact?, 2d joint as thick as the first, longer than wide, 8d much narrower but also longer than wide, 4th very small sub- transverse, dthand 6th very small strongly transverse ; the three last joints are absorbed in a large, elongate-oval, solid annulated club, which is al- most as long as the first joint and less compressed than in C. cact?. Mentum transverse, flat, subopaque, testaceous, not visibly punctured, broadly emar- ginate in front. Prothorax sculptured as the head, broadly emarginate in front, sides feebly rounded, base straight, anterior angles distinct, not rounded, hind angles obtuse. Scutellum shining, very finely sparsely punctulate. Elytra shining, not densely, finely punctured, with traces of rows of stronger punctures at the apex near the side margin ; sutural stria finely impressed and reaching almost to the middle. Prosternum in front of the cox very short, linear, carina more prominent in front, intercoxal process long, almost reaching the mesosternum. Carina of mesosternum with the free angle almost rectangular, not mucronate. Metasternum on each side opaque, not visibly punctured, in the middle slightly but abruptly elevated in an oblong, shining plate, which is somewhat narrowed in front and finely remotely punctulate. Abdomen opaque, first segment carinated in the middle. Legs stout, femora punctulate, tibia smooth. Length 1.75 mm. ; .07 inch. Enterprise; five specimens, found in May and June, on cut down palmetto trees feeding on the fermenting juice. C. semiglobosum Zimm. (Trans. Am. Ent. Soc. 1869, p. 250), is in my opinion well distinguished from C. estriatum. It is always smaller, shorter and more convex, the front margin of thorax distinctly produced in the middle, the punctation of head and thorax is much finer, that of the elytra less dense, fine in the scutellar region, stronger at apex and at the sides; the legs are stouter and less dark colored, the tibize smooth. 4, Sacium mollinum, n.sp.—Elongate-oval, shining, above pice- ous, thorax semicircular with the apex and sides pale, diaphanous anteri- orly, finely and moderately densely punctulate. Elytra minutely sparsely punctulate, pubescent, a humeral spot, a curved fascia at the apical third, and the side margin yellowish-testaceous.. Beneath piceo-testaceous, ab- domen and legs pale, metasternum densely punctulate. The yellow side margin is connected with the humeral spot and with the fascia ; the latter igs sometimes abbreviated at the sides or reduced to a spot on the dise. Length 1 mm, ; .04-.05 inch. Tampa and Enterprise, many specimens ; abundant on Pinus palustris in April and June. Shorter and more regularly oval than the other species and of different coloration. . 1878, | 307 (Schwarz. 5. Sacium splendens, nb. sp.—Elongate-elliptical, very shining, thorax semicircular, reddish with an indefinite dark spot in front of mid- dle, apex and sides pale, very finely sparsely punctulate. Elytra piceous- black with an indistinct reddish basal spot inside of the humerus and a common, broad, testaceous fascia behind the middle, exceedingly finely re- motely punctulate, pubescence only visible under a very high power. Un- derside reddish-brown, shining, hardly visibly punctulate, abdomen paler at apex, legs yellowish-testaceous. Length 7 mm. ; .03-.04 inch Tampa; many specimens beaten from dead leaves of Pinus palustris in April. Varies with the fascia interrupted by the suture, or not reaching the side margin. The apparently unpubescent and very shining elytra with the very fine punc- tuation will easily distinguish this species. 6. Scydmzenus divisus, n. sp.—Fusiform, shining ; head and tho- rax brown, impunctate, with coarse, erect, moderately long, brownish pubescence. Head not immersed in the thorax, with a thick brush of hairs each side behind the eyes ; antenne red, stout, longer than head and thorax, intermediate joints as long as wide, club 4-jointed, 8th joint globu- lar twice as large as the preceding, joints 9 and 10 subtransverse, each very little larger than the 8th, terminal joint oval, shorter than the two preceding together ; maxillary palpi with the penultimate joint slender, clavate, last joint not visible. Thorax trapezoid, very little longer than wide at base, smooth, transverse basal impression feeble, interrupted at the middle. Elytra not forming an angle with the thorax, with sparse, long, erect, grayish pubesence, red, evidently punctate anteriorly and smooth behind the middle ; punctate part divided in an inner and outer portion by a broad smooth humeral band, inner portion more finely and sparsely, outer por- tion more coarsely and densely punctured; humeral callus moderately elevated ; two distinct basal foveze each side of almost equal size; suture not elevated. Beneath piceous, abdomen pale at tip, legs red, femora mode- rately clavate. Length 1.15 mm. ; 4.5 inch. Enterprise; two specimens. Belongs in the group of S. capulosulus and is easily distinguished by the peculiar sculp- ture of the elytra. 7, Languria marginipenmis, 0. sp.—Red; head, and small rounded discoidal spot on the thorax, scutellum, outer half of femora, the larger part of the tibize and the tarsi blackish-green; antenne, metasternum, with the exception of the front margin, and the last ventral segment black; elytra greenish-blue or blue, margin and epipleure red. Head alutaceous, distinctly not densely punctured, antenne with joints 3-6 slender, 7-11 forming an abrupt club, joints 7-10 produced within. Thorax longer than wide, finely aciculate and distinctly not densely punctured, on the sides very little rounded and slightly sinuate before the hind angles ; the Schwarz. ] 308 | [Feb. 1, more or less rounded spot in the centre and occupies usually the fourth part of the length of the thorax, but is in some specimens reduced in size. Elytra shining, strongly striate-punctate, punctures finer towards the apex, interstices flat, finely alutaceous, obsoletely remotely punctulate ; the red color is usually confined to the thickened margin and to the epipleure, but in two specimens the last interstice also is indistinctly red in the middle. Prosternum sparsely punctured, almost smooth in front, mesosternum coarsely punctured, metasternum almost smooth, abdomen finely, remotely punctulate. The red and green colors on the tibie are not sharply sepa- rated ; the base and the upper edge, however, are always dark and the largest part of the lower edge always red. Length 7-9 mm. ; .28-.35 inch. Ft. Capron, Tampa, and Enterprise; six specimens. This species resembles in form L. tedata, it is, however, a little more elongate with the thorax longer. 8. Tomarus hirtellus, n. sp.—Oblong-oval, convex, shining, fus- co-testaceous. Head and thorax finely, sparsely punctulate, sparsely pubes- cent ; antenne less slender than in 7’. pulchellus. Thorax twice as wide as long, on the sides subsinuate before and slightly undulate behind the middle, base sinuated each side, basal impressions deep. LElytra with sparse, suberect, grayish pubescence, and with some scattered long erect hairs, strongly irregularly punctate in front, punctures becoming finer and obsolete towards the apex ; an indefinite, often abbreviated, fascia at the middle and another on the apical third black. Beneath finely, sparsely pubescent, pro- and metasternum evidently punctulate ; legs pale. Length 1.25-1.5 mm; .05-.06 inch. Smaller and shorter than 7! pulchellus and easily distin- guished by its more evident pubescence and stronger punc- tuation on the elytra. The pubescence of 7. hirtellus and the form of the thorax, whose side margin has the tendency to become serrulate, bring the genus Zomarus still nearer to Paramecosoma. 9. Lathropus pictus, n. sp.—Opaque, head and thorax ferrugineo- testaceous, the former densely rugosely punctulate, emarginate in front, antenne ferrugineous, second joint and the club blackish, joints 83—8 very small, together hardly as long as the club. ‘Thorax transverse, side mar- gins undulate, apical margin and base straight, anterior angles almost rectangular, hind angles prominent ; finely and densely rugosely punctu- late, without any trace of impressions, lateral lines feeble. Scutellum small, transverse. Elytra much less elongate than in ZL. vernalis, fusco- testaceous, finely punctate-striate, with numerous rows of exceedingly short, rigid, whitish hairs; a circumscutellar cloud and a common fascia, concave and dentate anteriorly, blackish. This fascia is formed of three indefinite spots on each elytron, the first at the suture a little behind the 1878. ] 309 : (Schwarz. middle, the second, oblong, in front and outside of the first, the third at the side margin. Metasternum and abdomen piceous, finely sparsely punctulate ; legs pale. Length .05 inch ; 1.25 mm. Smaller and especially shorter than JL. vernalis and dis- tinct by the dise of the thorax without impressions, by the sculpture and pubescence of the elytra and by the color. Haulover Canal, Volusia County; four specimens found under bark of a dead Quercus virens. 10. Lemophicus Chamerepis, n. sp.—Less elongate, de- pressed, glabrous, shining, bright rufo-testaceous, elytra pale ochreous. Head large, transverse, flat, not impressed on the disc and without median line, finely and sparsely punctulate, marginal line close to the margin in front and at the sides, base not margined ; antenne with distinct 3-jointed club ; labrum large, transverse, truncate in front. Thorax finely, sparsely punctulate, with a single lateral line joining the basal marginal line and with an impressed puncture of moderate size each side in the middle out- side of the lateral line ; anterior angles not prominent in either sex. Scutel- lum transverse, triangular. Elytra at base very little wider than the tho- rax, slightly dilated behind the humeri, which are obtuse but not rounded ; each elytron with six fine strie: the humeral stria more distinct and im- punctate, 5th stria also more distinct, obsoletely punctulate, the inner striz less distinct and feebly punctulate, sutural striz at apex more impressed than in front. Interstices flat impunctate. Head beneath, pro- and meso- sternum impunctate, metasternum and abdomen finely sparsely, last ven- tral segment more densely punctulate. Length 1.5-2 mm. ; .06-.08 inch. & Head wider than the thorax, front produced, emargi- nate at middle, distinctly sinuate each side, with the teeth long and acuminate; antennee slender, more than half the length of the body, with all the joints longer than wide. Thorax strongly transverse, sides oblique, convergent towards the base and subsinuate before the hind angles, which are obtuse; lateral line oblique; elytra as long as head and thorax together. ¢ Head as wide as the thorax, front produced, emarginate in middle, hardly sinuate at the sides, teeth much less prom- inent ; antennee less slender, outer joints as long as wide. Thorax less transverse, sides sub-parallel, slightly arcuate and sinuate before the hind angles, which are rectangular, lateral line straight; elytra a little longer than head and thorax together. — Schwarz. ] 360 f [Feb. 1, 11. Nemicelus marginipennis Lec.—The two sexes differ from each other most remarkably and might be easily mistaken for two distinct species. The form described by LeConte (Proc. Ac. Nat. Sc. 1854, p.79), I take to be the °\. The female differs chiefly by the following characters : Less elongate, opaque above, color of upper and underside darker. Head densely rugosely punctulate with an obtuse tooth behind the eyes, eyes smaller, less elongate and less oblique, more convex ; antenne with the first joint only one-half longer than wide, shorter than the two following to- gether. Thorax hardly longer than wide anteriorly, more dilated in front, not emarginate at apex, apical edge thickened, base much less lobed in the middle, surface densely rugosely punctulate. Elytra almost entirely covering the abdomen, less truncate at apex, distinctly pubescent, densely punctulate, striz less evident. Prosternum shining, punctate, process be- tween the front coxe hardly visible, propleurze opaque, sculptured as the thorax; mesosternum much smaller, less broadly rounded in front, dilated behind, shining punctate; metasternum and abdomen opaque, the latter less elongate, last segment not longer than the preceding with a large shal- low impression. Hind tarsi 4-jointed as in the male. The genus Nemicelus was first described by Dr. LeConte, and is certainly distinct from Hemipeplus. 12. Nemicelus microphthalmus, ° n.sp.—Linear, pale, yellow- testaceous. Head quadrate, subconvex, behind the eyes straight, then suddenly narrowed and forming a short neck, somewhat shining, sparsely and obsoletely rugose ; eyes small, round, convex, very coarsely granula- ted, mandibles deeply emarginate and black at tip ; antenne a little longer than head and thorax, first joint stout one-half longer than wide, shorter than the two following together, joint 2 globular, the following 4 joints as long as wide, equal, 7 and 8 a little larger than the preceding, the three last joints abruptly larger, 9 and 10 hardly transverse, terminal joint oval acuminate. Thorax but little longer than wide anteriorly, feebly and broadly emarginate in front, sides oblique, convergent towards the base, subsinuate anteriorly and broadly sinuate before the hind angles ; base al- most straight, not lobed, apical edge thickened, anterior angles obtuse; rounded at tip, posterior angles obtuse ; surface somewhat shining, indis- tinctly, rugosely punctulate with a faint trace of an impressed median line, basal impressions large anddeep. Scutellum opaque, subquadrate and alittle broader behind, apical side rounded, Elytra almost covering the abdomen, subopaque, paler than the head and thorax, darker at the sides and with a short dark line on each elytron near the suture at the apical fourth, densely and equally rugosely punctulate with hardly any trace of strie. Pro- and mesosternum shining, sparsely punctulate, propleurze opaque, sculptured as the thorax, front coxe very narrowly separated, metasternum and abdo- men subopaque densely and finely punctulate, last ventral segment hardly longer than the preceding with a round impression, occupying nearly the whole surface.

A single specimen from Enterprise, found in May, attracted by the light, is before me, another specimen from Tampa is in the cabinet of Dr. LeConte. Smaller and narrower than the smallest females of JV. marginipennis and very distinct, especially by the form of the head and by the small, round eyes. 13. Philothermus puberulus, n. sp.—EHlongate-elliptical, trans- versely convex, dark chestnut-colored, shining, above with distinct, fine, erect pubescence and with some longer hairs at the sides. Head sparsely punctured, antenne shorter than in Ph. glabriculus, apparently 10-jointed, joints 2 and 8 slender, the following six joints small, 7-9 strongly trans- verse, joints 10 and 11 forming a solid club asin Cerylon. Thorax less transverse and less strongly margined than in Ph. glabriculus, rounded on the sides, moderately sparsely punctured. Scutellum transverse, shining, with a few punctures. Elytra strongly striate-punctate, interstices finely, sparsely punctulate. Prosternum and propleure distinctly, not densely, metasternum and first ventral segment in the middle finely and sparsely, at the sides very coarsely punctured, segment 2-4 each with two trans- verse rows of strong punctures, last segment more finely punctulate ; legs testaceous. Length 2 mm. ; .075 inch. Abundant in Florida under old bark of Pinus palustris. Smaller, narrower and more convex transversely than Ph. glabriculus, with the sculpture above and beneath stronger and at once distinguished by the much more evident pubescence and by the form of the antennal club. By this last charac- ter Ph. puberulus forms a passage to Cerylon. Sexual charac- ters are not evident ; some specimens have the sides of thorax less rounded ; these are probably the males. 14. Olibrus princeps, n. sp—.Rounded-oval, pale rufo-testaceous, thorax with a large brownish discoidal spot. Elytra black each with a large, oval, bright orange-colored spot at the suture before the middle, outer half of the basal margin and the lateral margin narrowly, apex broader yellow ; very finely striate, striz minutely and remotely punctu- late, interstices obsoletely sparsely punctulate, punctures more distinct near the lateral margin. The sutural stria alone is deeper impressed ; mes- osternum not protuberant. Length 2.5 mm.; .10 inch. One specimen in the collection of Mr. H. G. Hubbard from New Smyrna; another specimen found by me at En- terprise in May is in the cabinet of Dr. LeConte. A very striking species by its color, belonging in the group of O. apicalis. PROC. AMER.

Elytra shining, dis- tinctly moderately densely punctate, an oval discoidal spot, the side mar- gin and the apex yellow. The yellow side margin is throughout of equal width, following the undulation of the side margin of the elytra ; at the apex it turns inwards and becomes broader, but does not reach the suture. Mouth, antenne, epipleuree, legs, sides and apex of abdomen, yellow, Length 1.35-2.25 mm. ; .07-.09 inch. 3 Head and front margin of thorax yellow. Very common in Florida on swampy meadows in the Pine lands. Resembles in coloration certain varieties of H. undulata, but it is longer, less convex and also a little smaller, with the thorax opaque and less distinctly punctu- late; the yellow side margin is always of equal width and never broken into spots. 17. Strigoderma exigua, n. sp.—Oblong-oval, convex, shining, above glabrous and only at the sides fringed with a row of longer hairs. Head piceous with greenish reflection, transversely convex behind, flat- tened in front, moderately sparsely punctate and not rugose, vertex more remotely punctulate; clypeus parabolical, not separated from the front, broadly rounded at apex and strongly reflexed ; antenne piceous. Thorax transversely convex, emarginate at apex, at the sides strongly rounded and narrowed in front of middle, not angulated in the middle, slightly nar- rowed towards the base, which is straight and not produced in the middle: hind angles obtuse, rounded; surface piceous with greenish reflexion, apex and sides pale ochreous, sparsely punctured without impressions.

Three specimens are before me which I found on oak shrubs on the sand hills east of Lake Altapopka in May. Easily distinguished from our two other species by its smaller size, more regularly oval, convex form, by the glab- rous upper surface, by the sculpture of head, thorax and elytra and by the formation of the front tibie. 18. Taphrocerus puncticollis, n. sp.—Elongate, above black- ish-blue, or black with faint eneous tinge, shining. Head less strongly excavate, very finely alutaceous, distinctly, moderately sparsely punctate, punctures deeper than in 7. gracilis. Thorax transverse, narrowed in front when viewed from above, sides sinuate before the hind angles, which are rectangular, base strongly lobed in the middle, lobe broadly emarginate; surface uneven with a distinct carina in front of the hind angles, very finely alutaceous, coarsely unequally punctured, each puncture bearing a very short scale-like hair. Scutellum transverse, shining. Elytra im- pressed at base, impressions on the disc not obvious, serrate at the outer apical angle; anteriorly moderately strongly striate-punctate, punctures obsolete towards the apex, each with a very fine, short hair, interstices on the disc unequal ; the striz therefore appear subgeminate ; humeral carina broadly interrupted at middle. Beneath bluish-black or black, metasternum coarsely punctured ; abdomen with sparse shallow punctures, last segment with a deep, semicircular marginal sulcus. Length 5 mm.; .20 inch. Enterprise and Cedar Keys; two specimens. More elon- gate than 7. gracilis and distinguished by the deeper punc- tuation of head, thorax and metasternum and by the elytra less even, without patches of pubescence; from T! agriloides it differs chiefly by the form of the thorax, which in the lat- ter species is not narrowed in front when viewed from above. 19. Brachys fascifera, n. sp.—Similar to B. ovata, but shorter, broader in front and more attenuate behind, and easily distinguished by the broad white fascia on the elytra and by the formation of the prosternum. Head and thorax as in B. ovata, the former less strongly excavated.

Fissure of prosternum not reaching the hind margin, but leaving a comparatively broad margin intact, apex of metasternum in the middle suddenly and deeply emarginate. Last ventral segment with the usual marginal sulcus, not emarginate in the male; broadly rounded in the 2, less broadly in the ¢'; anus very finely pectinate. Length 4.5-5 mm.; .18-.20 inch. Widely distributed in Florida and not rare; lives on Quereus virens.

Very abundant everywhere in Florida. In form and size this species resembles P. /evigatus; the elytra are however less triangular and more rounded at the sides; it differs also by its color and by the thorax not being impressed at the sides. Very probably there will also be a difference in the sexual characters of the males but I have not seen the & of P. levigatus.. In P. purpureus the last ventral segment of the % has a similar impression but the two processes are more separated from each other and each terminates in three teeth. 21.

This species has exactly the aspect of a small Crepi- dodera and is distinguished by its less convex form, by the quadrate thorax, which is much narrower at the base than the elytra, and by the form of the metasternum. The sculp- ture of head and thorax is subject to variations as in the other species ; but the form and sculpture of the sterna ap- pear to offer more reliable characters. i 29.

Dyschirius falciger, n. sp.—Rather slender, black, very shining, with a slight brown-metallic tinge ; palpi, antenne and legs ferruginous. Head smooth, convex, with the frontal and tranverse impressions deep ; front truncate, with small, acute lateral angles. Eyes convex, prom- inent, as usual. Prothorax about as wide as long, rounded on the sides, narrowed in front, lateral impressed line not continued to the base. Elytra with striz coarsely punctured at base, gradually becoming finer, obliter- ated at about three-fourths of the length ; tip with faint traces of strive, and a rather large, oblique impression, representing the end of the 7th stria. Front tibiz with a small, acute tooth above the apical prolongation, which is straight and slender ; apical spur very long and strongly curved. Length 3 mm.; .12 inch. Tampa and Lake Harney; received also from Dr. Emil Brendel. This species is not as slender as D. terminatus, but is proportioned like D. analis, from which the characters given above easily distinguish it. WD. curvispinus Putz., is described as having the apical spur of the front tibise curved, but it is otherwise quite distinct by the ferruginous color, and by the striz of the elytra not obliterated towards the tip. The preescutellar puncture in this species is large, and the dorsal punctures usually seen on the 8d interspace are not apparent. 2. Onota trivittata, n. sp.—Elongate, depressed ; bright rufo-tes- taceous, shining. Head narrowed and rounded behind the eyes, flat, with- out impressions ; edges larger and more prominent than usual. Prothorax not as wide as the head with the eyes, longer than wide, narrowed behind, sides rounded in front, then sinuate to the basal angles which are not rounded, and slightly divergent ; side margin reflexed, not very narrow, dorsal line fine, basal impressions small. Elytra wider than the prothorax, obleng, truncate at base, somewhat obliquely, broadly truncate at tip, flat, side margin reflexed, striee composed of very fine punctures ; ornamented with a common sutural black stripe, and a sub-marginal one, which ex- tends along the apical truncature to meet the sutural one ; the latter ex- tends to the 2d stria, and behind the middle is slightly dilated for one- fourth the length to reach the 4th stria. Beneath uniform rufo-testaceous. Length 5 mm.; .20 inch. Florida, collected by Mr. A. Bolter, of Chicago, to whom LeConte. | 374 [Feb. 1, Lam indebted for two specimens. This beautiful species is easily recognized by the peculiar coloration. I have referred it to Onota Chaud.. because the 4th joint of the tarsi is broad, and deeply bilobed, and the claws are pectinate. The teeth of the claws are only four in number, and are much larger than in the other species. The tarsi are glabrous on the upper surface. The last joint of the maxillary palpi is cylin- drical, slightly oval, and more than twice as long as the pe- nultimate joint; the last joint of the labial palpi is oval, pointed and somewhat flattened. Mentum not toothed. - It is by this last character that it mainly differs from Callida, with which it agrees in having two bristles near the tip of the hgula. 3. Platynus floridanus, n. sp.—Dark-green, shining, slightly bronzed, antennee, legs and under surface piceous-black. Prothorax scarcely longer than wide, sides broadly rounded, and finely margined ; apex emarginate, front angles slightly rounded; base broadly sub-trun- cate, oblique towards the side angles, which are obtuse and almost rounded ; basal impressions rather long, not punctured ; dorsal line ex- tending to the posterior transverse impression, which is faint. Elytra one- third wider than the prothorax, emarginate at base, obsoletely sinuate at tip; strie fine, but well impressed, not punctured ; interspaces flat, 3d with usually 6 small dorsal punctures, the 1st and 2d adjacent to the 3d stria, 3d and 5th upon the interspace, 4th and 6th adjacent to the 2d stria. Hind tarsi with the 1st, 2d, and 3d joints broadly grooved on the outer side. Length 9.6 mm.; .35 inch. Capron and Lake Harney, abundant. This species is closely related to P. californicus, and differs only by the hind angles of the prothorax being much less distinctly de- fined; in fact, almost rounded. The size is usually larger, so that the smallest individuals of P. floridanus are equal to the largest of californicus, but this is a character of small 1m- portance. Closely allied to these two is the following: 4, Platynus texanus, n. sp.—Less shining, with a green-metallic reflection. Antenne black; under part of ist joint, palpi and legs testa- ceous ; knees, tarsi and tips of tibize blackish-piceous. Prothorax, as in P. floridanus, except that it is a little wider than long. Elytra simi- larly striate and punctured, but with the strie a little deeper; epipleure testaceous, under surface black.

It is much larger than the other species in our fauna, as the elytra of the largest specimen of semi- ‘ opacus in my collection are 12.5 mm.; .475 inch long. This species seems to have a rather wide distribution in the Atlantic States. Dr. C. Zimmermann once told me that he had found a large blue Greotrupes, without impressed strize, in South Carolina, and if I mistake not I have seen a similar specimen from Maryland, in Mr. Ulke’s collection. 70.

A specimen from Texas (Bel- frage) agrees in all respects except that the antenne are short and less slender, with the 3d joint more evidently longer than the 2d or 4th. I am disposed to think the difter- ence is sexual. 74. Anchastus Longulus, n. sp.—Elongate, pubescent, red-brown, elytra and legs paler. Head densely and strongly punctured, front not concave, margin fine, not reflexed. Prothorax nearly one-half longer than wide, strongly and densely, not coarsely punctured, narrowed in front, sides nearly straight, hind angles bicarinate. Elytra with punctured strie, interspaces nearly flat, finely not densely punctured. Antenne with 35d joint one-half longer than the 2d ; united equal to the 4th. Length 10 mm.; -40 inch. Enterprise ; one specimen. A smaller specimen (7.2 mm.; .29 inch) from Louisiana was given me by Mr. Salle, which is a little less elongate, but not otherwise different. 7o. Amchastus fuscus, n. sp.—Elongate, pubescent, dark fuscous above, red-brown beneath. Head coarsely punctured ; punctures umbili- cate, front broadly concave. Prothorax coarsely punctured, longer than wide, gradually narrowed in front, sides straight, hind angles unicarinate. Elytra with coarsely punctured strive, interspaces convex, sparsely and finely punctured. Antenne brown, half as long as the body, strongly serrate, 2d joint very small, 3d as large as the 4th.

Legs slender. rather long, middle coxee separated by the metasternal process ; middle legs received in transverse excavations, which extend on the epi- pleurz ; hind legs received in excavations which occupy the whole of the length of the 1st ventral segment, and extend to, but not upon, the edge of the elytra; tarsi broad, 1st joint not elongate, 5th not narrower nor longer than the 4th; claws small, divaricate, appendiculate, ventral seg- ments 5, as usual ; Ist short, occupied by the excavations for the hind legs ; 2d, 3d and 4th equal, each about twice as long as the 1st; 5th nearly as long as the two preceding, broadly rounded ; the sutures are equally plain and straight. Elytra striate. This genus is allied to Dorcatoma and Cenocara, but differs from both by the elytra being striate, by the 2d joint of the antenne being larger, and by the form of the metasternal process which is much narrowed at base in Dorcatoma, and very short in Cenocara. Having seen but one specimen, lL am unwilling to risk it by an attempt to expose the pros- ternum, especially as the genus is very well characterized without reference to that part. 99. Byrrhodes setosus, n. sp.—Robust, oval, convex, obliquely nar- rowed in front, blackish-brown (somewhat shining where the hair is re- moved), densely clothed with coarse white curled hairs, very finely and densely punctulate. Head with a transverse frontal impressed line near the margin ; sides obliquely margined. Prothorax short, of the same form as in Cenocara, outline when viewed from above oblique. Scutellum flat, rounded. Elytra with well impressed striz, the two outer ones deeper be- hind the middle ; interspaces wide, flat, the outer ones slightly convex be- hind ; lateral edge finely margined from base to tip. Beneath nearly smooth, very sparsely punctulate. Sterna glabrous (by abrasion ?), abdo- men hairy. Length 3.5 mm.; .14 inch. Capron; one specimen. On superficial view, this insect might be readily mistaken for a small species of Byrrhus. 100. Elaphidium tectum, n. sp.—Elongate, slender, brown, clothed with short fine rather dense dirt-colored pubescence, scarcely mottled on the elytra. Antenne ((<) as long as the body, joints 3-10 each with a spine at the inner apical margin; the spine of the 3d is about one-fourth as long as the 4th joint, the others diminish gradually in Jength ; the outer apical angle of the joints 5-7 is also armed with a small spine. Prothorax a little wider than long, moderately rounded on the sides, densely punc- tured, with a smooth dorsal line more distinct behind the middle, and a discoidal round callus each side in front of the middle; on the deflexed sides near the base are seen a few large round punctures or fovee.

Thighs of the hind legs with a short spine on the inner side. Length 15.6 mm.; .63 inch. Cedar Keys; two 3. This species is related to #. mucro- natum and incertum, but the antenne are not longer than the body, and the pubescence is more uniform ; the punctures of the elytra are also more distant. It seems to resemble WH. la- natum Chevr. (Am. Ent. Soc. Fr. 1862, 260) from Cuba, and I should consider it as the other sex of the same species, ex- cept that the outer angle of the 3d and 4th joints is not armed with a spine. 101. Leptostylus transversatus Chevr. Ann. Ent. Soc. France, 1862, 248. Enterprise. The specimens agree perfectly with the de- scription given of this Cuban species, which was not previ- ously known in our fauna. 102. Leptostylus arcuatus, n. sp.—Fuscous, densely clothed with gray hair. Elytra flattened on the disc, hind third of surface smoky- brown, limited in front by a curved blackish line, concave forwards ; this line is angulated about the middle of the width, then again concave for- wards, and joins a lateral narrow black line, which is dilated behind the humerus ; asperities black, sparse, small, arranged in distant rows ; tips strongly and obliquely truncate, outer angle prominent ; punctures coarse, rather densely placed. Prothorax without discoidal inequalities, nearly twice as wide as long, sides oblique from apex to beyond the middle, where they are distinctly angulated, then narrowed to the base; there is a small black spot extending from the base to the lateral angle. Beneath brown, finely pubescent, not mottled, legs scarcely mottled ; antenne a little longer than the body, punctured and annulated. Length 8 mm.; .32 inch. Tampa; one specimen. wee tle 4. 3.

Antenne as long as the head and prothorax, rather slender. 3d joint a little longer than the 4th; 8th, 9th and 10th wider and larger, scarcely as long as wide, 11th longer, oval. Palpi with the last joint strongly securiform, mentum obovate, transverse, with two shallow impressions. Prothorax sub-cylindrical, slightly rounded and sub- sinuate on the sides, which are narrowly margined, hind angles small, acute, or rectangular. Elytra a little wider than the prothorax sub-cylindrical, humeri not prominent, striz composed of large close punctures, interspaces narrow. Epipleure narrow, not reaching the tip, impinged upon by the 4th and 5th ventral segments, which are rounded at the sides. Legs long, slender ; tarsi with the 1-3 of the front and middle pair broad, and the 1st and 2d of the hind pair less dilated, brush-like beneath ; penultimate joint small, last joint as long as the others united, claws large, simple. 118. Dignamptus stenochinus, n. sp.—Elongate, shining black, with a bluish gloss. Head densely punctured. Prothorax more strongly punctured, one-half longer than wide, sub-sinuate on the sides behind the middle ; hind angles small, acute, prominent.

Dignamptus langurinus, n. sp.—Linear-elongate, black, with a slight metallic gloss. Antenne stouter, more strongly and more gradualiy thickened externally, the 6th and 7th joints being wider than the preceding, though not so wide as the following. Head finely punctured. Prothorax strongly punctured, one-half longer than wide, slightly narrower behind, hind angles rectangular, not prominent. Elytra slightly wider than the prothorax, strize composed of oval punctures, in distance equal to their long diameters ; interspaces wider than the strie, flat, smooth. Be- neath as in the preceding.

Larger and stouter than P. testacea, and easily known by the black and coarsely punctured legs. In this respect it resembles P. pilifera from Lower California, from which it differs only by the epipleuree being smooth and glabrous, while in P. pilifera they are pune- tured and setose. ‘121. Platydema crenatum, n. sp.—Oval, rather elongate, con- vex, black, shining. Head punctured in front, transverse impression faint. Prothorax sparsely, finely punctulate, base bisinuate, not margined, each side with a broad, shallow impression. Elytra with deep, very coarsely punctured striz.

Pygidium equally, densely, finely punctured. Abdomen less densely punctured, 5th ventral segment vague, impressed. Length 3mm.; .12 inch. Tampa; two specimens, also found in Georgia, under pine bark. This species is smaller, narrower and more convex than H. parallelus, and differs by the front angles of the prothorax not being acute and prominent. It has the same form as JZ. thoracicus and piliger, but differs by the elytra being more finely punctured, without erect hairs, and by the pygidium being not sparsely but densely punctured. I do not find mentioned in any work that the 3d, 4th and 5th ventral segments in this genus are longitudinally, deeply impressed near the sides, so that the margin appears to be thickened. 123.

Elytra finely not densely punctured, punctures here and there, forming rows (but not indicating strive); there are some erect hairs, especially near the tip, and at the sides. Pygidium sparsely punctured. Beneath punctured, last ventral segment not impressed. Length 2.5 mm.; .10 inch. Florida, Georgia and South Carolina; under pine bark. I have adopted the name which it bears in the collection of Dr. Zimmermann. This species is more slender than H. par- allelus, and differs by the sparse, erect hairs, by the punctures of the elytra being less fine and more distant, and by the pygidium being sparsely punctured. In these respects it agrees with #7. thoracicus, but differs in color, and by having fewer erect hairs. Three new species remain in my collection, which may be described on the present occasion ; the subjoined table gives the essential characters of all the species in our fauna. 124.

Beneath punctured; last ventral segment brvadly impressed, apical part convex. Length 4.2 mm.; .18 inch. Oregon; collected by Lord Walsingham. Much larger than HZ. parallelus, and easily distinguished by the less con- vex form, more strongly margined prothorax, and by the elytral punctures being stronger, and placed in rows. 125.

Elytraa little wider than the prothorax, punctured, striz punctured, slightly impressed, obsolete towards the sides ; marked with a small rounded humeral spot. Beneath shining, finely punctured, legs entirely black; front coxze contiguous. Length 6 mm.; .23 inch. Detroit ; June ; one specimen. 56. Canifa pallipennis. Elongate, rugosely punctured, finely pubescent. Head and prothorax black, the latter more than twice as wide as long, hind angles nearly rectangular, basal impressions broad, distinct. Elytra pale testaceous. Beneath and legs testaceous, abdomen and anten- ne darker; second and third joints of the latter small, united shorter than the fourth. Length 2.7 mm.; .10 inch. Marquette, Lake Superior. Similar to C. pusilla, but with the head and prothorax darker, and the elytra pale. 57. Dirczea fusca. Elongate, fuscous brown, densely rugosely punctured, and clothed with short sericeous brown pubescence. Head perpendicular, more strongly punctured. Antenne and palpi ferruginous, the former with third joint not longer than the fourth, following joints scarcely diminishing in length, longer than wide, eleventh longer. Pro- thorax a little longer than wide, apex rounded into the sides; hind angles obtuse, rounded at tip. Elytra with faint traces of three elevated lines. Beneath densely punctulate. Length 8.7 mm.; .384 inch. Marquette, Lake Superior, Virginia and North Carolina.

Several specimens of this curious insect were found at Marquette, and among them are c'S' in which the two pro- cesses of the apical edge of the last ventral segment are very short, and scarcely apparent, though the anterior tubercle or spine and the large excavation are as well developed as in the other specimens. 60. Proctorus decipiens Lec. ibid. 213, (Hncalus.) 3 Apical part of last ventral segment suddenly transversely depressed, with a short erect spine each side. Marquette. The differences in the rostrum upon which I separated Hncalus from Proctorus, are only sexual; and the peculiar ventral armature of the 7 shows that they consti- tute but one genus. 61. Orchestes canus Horn,* n. sp. Black, sparsely clothed with grayish pubescence. Antenne testaceous, funicle six-jointed. Thorax broader than long, apex one-third narrower than base, sides arcuate, disc coarsely punctured. Elytra oval, gradually narrowed posteriorly, dise con- vex, deeply and rather broadly striate, strize with coarse, deep and closely placed punctures, intervals irregularly biseriately punctured, the punc- tures bearing short grayish hairs. Body beneath and legs black. Length 3o9mm.; .12 inch. The posterior femora are strongly thickened. This species cannot be con- founded with any other than pallicornis, from which the deeply striate elytra, and very evident grayish pubescence will distinguish it. Specimens are before me from Isle Royale and Escanaba, Michigan, and from San Juan, Colorado. 62. Orchestes minutus Horn, n. sp. Black, sparsely clothed with grayish pubescence. Antenne piceous, scape and first joint of funicle paler, the funicle 6-jointed. Thorax broader than long, apex scarcely narrower than base, sides arcuate, surface coarsely punctured. Elytra oval, broadest at middle, dise slightly flattened, deeply striate, strize with indistinct dis- tant punctures, intervals wrinkled, irregularly, finely, biseriately punctu- late. Body beneath and legs black. Posterior femora feebly thickened. Length 2 mm.; .08 inch. This species resembles rufipes, but is somewhat smaller, dise of elytra flatter and with entirely black Jegs, and with the thorax much more arcuate at middle.

Elleschus bipunctatus Linn. Faun. Suec. No. 599 (Cureu- lio): Schénh. Cure. iii. 322; vii, 187: &e. Detroit and Marquette. The European synonymy of this species mmay be found in the references given above. The dif- ferences between this genus and Alyca (Lec. Rhynch. 209), do not seem sufficient to warrant the retention of the latter. The species upon it was established, Hrirhinus ephippiatus Say, differs from bipunctatus by finer punctuation, and pale yellow color, with a large sutural dark spot on the elytra. There are other species indicated by the specimens in my collection, but I do not*feel prepared to define them accu- rately without a larger series. 64. Acalyptus Carpini Herbst, Col. vi, 204; pl. 74, f 3; Gyll. Schoénh. Cure. iii, 447: &e. Michigan and Massachusetts; first known from Northern Europe. A small blackish insect, densely clothed with sil- very gray sericeous pubescence, and easily known by the ventral sutures being straight the pygidium exposed, and LeConte.] 622 [April 18, the claws simple and divergent. The antenne and legs are yellow ; sometimes the elytra are rufous, with the suture blackish. 65. Zygobaris subcalwa. Of the same size and form as Z. con- spersa, sub-rhomboidal, black, rather shining, thinly clothed with short pubescence, and without scales. Beak as long as the head and prothorax, curved, slightly thickened at the base, punctulate ; head finely punctate. Prothorax not wider than Jong, gradually narrowed in front, sides nearly straight, constricted near the tip; surface densely, not coarsely punctured, base bisinuate. Elytra wider behind the base, humeri oblique, striz deep, interspaces rather wide, flat, each with a row of small punctures. Beneath densely punctured, finely, sparsely pubescent; claws small, approximate, but scarcely connate at base. Length 2 mm.; .08 inch. Detroit; one specimen found; I have two others from Pennsylvania. Differs from Z. conspersa chiefly by the finer punctuation, and the absence of scales. 66. Pityophthorus annectens. Elongate-cylindrical, brown, shining, with a very few slender erect scarcely serrate yellow hairs. Pro- thorax longer than wide, in front roughened almost conceutrically for about one-third the length, sides and base finely sparsely punctured, punctures becoming larger, as they approach the roughened surface. Elytra with ap- proximate rows of small punctures, interspaces transversely rugose; api- cal declivity retuse, deeply impressed near the suture, which is elevated ; sutural tip rather acute. Front tibise with two small teeth. Length 16 mm. ; .06 inch. 3. Head broadly concave, opaque with shallow punctures, concavity fringed with long yellow hairs. 2. Head slightly convex, strongly and deeply punctured. Tampa, Florida, on yellow pine; Mr. E. A. Schwarz. This species is of slender form, and is most nearly allied to P. ni- tidulus, but is smaller, and has the prothorax more finely punctured. The color is also difterent, the Californian and Alaskan nitidulus being black, while this is always brown. 67. Pityophthorus consimilis. Yellow brown, shining, with a few erect yellow hairs, of the same form and sculpture as P. annectens, except that the obtuse elevation of the apical declivity of the elytra, and the corresponding part of the suture are sparsely crenate. The antennze and legs are yellow, and the form is perhaps a trifle more robust. Length 1.6 mm.; .06 inch. 3. Head flat, slightly pubescent, with a large, sub-quadrate, densely punctured opaque spot occuping nearly the whole upper surface, and di- vided by a longitudinal impressed line ; sides shining, sparsely punctured . @. Head slightly convex, strongly punctured. Marquette, Lake Superior, Detroit. The females of this 1878. | 623 [LeConte. and the preceding are undistinguishable, except by the char- acters given above; the do are however easily recognized. 68. Pityophthorus hirticeps. Yellow brown, shining, cylindri- cal, less slender than the two preceding species, sparsely retose with fine, erect yellow hairs. Prothorax a little longer than wide, roughened con- centrically for one-third its length ; sides and posterior part strongly, rather densely punctured, with a narrow smooth median space. Elytra with ap- proximate rows of punctures, interspaces irregularly transversely rugose ; apical declivity retuse and crenate, deeply concave near the suture, which is elevated and also crenate. Length 1.6 mm.; .06 inch. d': Head broadly concave and opaque, fringed with long yellow hair. ®. Head slightly convex, strongly punctured. Marquette, Lake Superior. Related to the two preceding, agreeing with P. annectens in sexual characters, but with the crenations of the apical declivity of the elytra stronger than in P. consimilis, while the form is a little more robust than in either. 69. Pityophthorus pusio. Cylindrical, shining, piceous, witha few erect yellow hairs behind the middle of the elytra. Prothorax not longer than wide, roughened in front almost to the middle, strongly and densely punc- tured at the sides and behind, with a large, smooth, well-defined dorsal space. Elytra with small punctures, arranged in tolerably regular rows, apical declivity broadly concave, slightly retuse each side, with about three very small teeth; suture elevated, also with three or four slight inequalities. Front tibise with two very faint small teeth. Length 1.6 mm.; .06 inch. Marquette, Lake Superior; one specimen. The head is re- tracted so that the front cannot be seen. This species is of the size and form of P. pulicarius, but the elytral sculpture and the apical declivity are quite different ; it is more nearly related to the Californian P. puncticollis, but differs by the more robust form, and by the sparse crenations of the apical declivity, which are wanting in that species. . 70. Pityophthorus opaculus. Cylindrical, slender, testaceous, head and disc of prothorax darker ; anterior half rather strongly asperate, sides and posterior half sub-rugosely punctulate, dorsal line smooth, narrow. Elytra finely alutaceous, nearly opaque, marked with scarcely perceptible distant strize of very fine punctures ; apical declivity neither retuse nor con- cave, suture elevated, limited by a distinct strixs. Length 1.38 mm.; .05 inch. Marquette ; one specimen. This species must be placed after P. comatus in my table (Rhynch. 852). The head is punc- tured, and slightly convex, the legs and antenne are yellow. 71. Pityophthorus plagiatus; Xyleborus plagiatus Lec., Tr. Am. Ent. Soc. 1868, 161 ; Rhynch 361. / LeConte. ] 624 [April 18, Marquette ; not rare. The club is transversely annulated, and it therefore belongs to Pityophthorus; the sexual difter- ences indicate that Xyleborus hamatus Lec., Am. Ent. Soe. 1874, 72, isthe 2 of carinulatus Lec. ibid. (Pityophthorus car. Lec., Rhynch. 352). 72. Pityophthorus sparsus. Xylevorus sparsus Lec., Tr. Am. Ent. Soe. 1868, 160. Marquette, Lake Superior; rare. This species, as is shown by the examination of well preserved specimens, has the club y I I ’ transversely annulated,and therefore belongs to Pityophthorus. There seems to be no sexual differences in the declivity of the elytra, but the @ has the head fringed with very long hair. 75. Xyleborus punctipennis. Slender, cylindrical, piceous, shining, thinly clothed with long erect yellow hair, granulato-asperate for more than one-half the length, sides and behind densely and coarsely punc- tured; smooth median line rather wide, very distinct. Elytra coarsely punctured, though not in altogether regular rows, suture elevated, and su- tural stria deep for the whole length: declivity oblique, retuse, concave part coarsely punctured ; there are two acute discoidal cusps, and several small indistinct marginal ones, the most anterior of which is near the su- ture and more prominent. Front tibiz moderately dilated, bidentate. Length 2.5 mm.; .10 inch. Marquette, Lake Superior; one 2 specimen. This species might be easily confounded with Pityophthorus sparsus, but on comparison the difference in the antennal club is quite obvious; in the present case it is thicker, and obliquely truncate at tip, so that the proximal half at least is smooth and shining, and limited by a curved line. The punctures of the prothorax and elytra are coarser and more numerous, and. the apical declivity is also punctured. 74. Kylocleptes decipiens. Slender, cylindrical, brown, shining, sparsely clothed with erect yellow hairs ; antenne and Jegs yellow. Pro- thorax longer than wide, slightly asperate in front with transverse rugosi- ties ; sides and behind coarsely but not densely punctured ; median line and a smooth space each side well defined. Elytra ,j' coarsely punctured, punctures not arranged in rows; declivity nearly perpendicular, scarcely retuse, slightly impressed along the suture, which is feebly elevated. Head convex, finely punctured ; front tibiz moderately dilated, serrate with four or five very smal] teeth. Length 1.3 mm.; .05 inch. Detroit; one specimen. Thisspecies greatly resembles in sculpture Pityophthorus pulicarius, but is more slender, and the 1878. ] 625 {LeConte. antennal club is very different ; the sutures are long curves, concentric with the apical margin, and the first joint is gla- brous, shining and elliptical in form. To this genus should be referred the Alaskan Bostrichus concinnus Mannh. Bull. Mosc. 1852, 358; Tomicus conc. Lec., Tr. Am. Ent. Soc. 1868, 164; Rhynch. 367. Only 22 have thus far been collected. 7. Tomicus balsameus. Blackish piceous, or brown, cylindrical, shining, clothed with long erect yellow hairs. Prothorax longer than wide, asperate for about one-half the length, then strongly but not very densely punctured at the sides and behind ; median space smooth, narrow, badly defined. Elytra with striz composed of large rather distant punc- tures, interspaces with equally large but very distant punctures ; declivity concave, sparsely not deeply punctured, margin with several small teeth and two large ones ; the apical part of the margin is not a continuous ridge. Front tibie dilated, with fourdistinct teeth. Length 2.3 mm. ; .09 inch. Oo Head flat, shining, hairy with very long yellow hairs ; the four larger teeth of the apical declivity less prominent. @ Head finely punctured ; carinate with an acute elevated line ; four larger teeth of apical declivity very prominent. Central New York, where it has seriously injured the forests of Abies balsamea. For an account of the ravages of this insect see the Report of the Botanist in the 28th An- nual Report of the New York State Museum of Natural History, 1874, p. 32-38. I am indebted to Mr. J. A. Lintner, of the State Museum, at Albany, for a series of speci- mens. Some care will be necessary to distinguish this in- sect from Xyleborus punctipennis, but apart from the difter- ences of theanntenal club, the prothorax of 7. balsameusis less densely punctured, the striz are more distinctly formed, and the apical declivity is less punctured, with the teeth (9) more prominent, and not distinctly separated from the ele- vation of the margin of the declivity. The front tibiz are more distinctly toothed. The sutures of the club are straight and transverse, so that it belongs to the division Orthotomicus Ferrari, and may be placed in the table (Rhynch. 363), after latidens, to which it has no resemblance. 76.

Of the same size and form as the preceding, but quite different in sculpture. 78. Scolytus unispinosus Lec. Rhynch. 372. Marquette, Lake Superior; one specimen. This differs from the two specimens from Oregon upon which the species was established, by the punctures of the elytra being not so small, and by the spine of the first ventral segment being much less developed, becoming in fact a small tubercle; the elytra are fringed with brown. [I consider none of these as specific characters. 79. Scolytus rugulosus Ratzcburg, Ins i, 230: pl. ee toi: This isa suitable opportunity to notice the introduction of this European species into the United States. I have re- ceived specimens from Elmira, N. Y., where it attacks peach trees. According to Ratzeburg it is rare in Germany, but is found upon plum and apple trees. 80. Choragus Harrisii. Elongate-oval, sub-cylindrical, blackish- brown, shining, finely pubescent. Prothorax finely less densely punc- tured, not opaque ; elytra with deep coarsely punctured striz, interspaces not wider than the striz, scarcely punctulate. Length1.2 mm.; .05 inch.

Color transparent white, mandibles and anal appendage castaneous. Form cylindrical, very slightly flattened beneath, hardly narrowed lat- erally in front and behind. Body glabrous, except a few hardly visible hairs upon the sides, without legs. Length 0.10-.12 inch.; width about 0.03 inches. Head not quite as broad as the segments of the abdomen, convex, trans- verse, enlarged posteriorly; sides rounded, convex ; anterior border nearly straight, posterior border emarginate ; above and below a few long bristles. No ocelli. Antenne short, inserted in depressions on the anterior angles of the head, of four joints increasing in length, the first very short, transverse, the second smaller, about as long as broad, the third longer than the pre- ceding, with a short oval lobe below, before the tip, the fourth twice as long as the third, slender, blade-shaped, tipped with a minute spine. . Labrum trausverse, somewhat enlarged anteriorly, borders nearly straight, anterior angles rounded, with long stout spines above and below. Mandibles as long as the antenne, stout, curved, three-toothed with a large hatchet-shaped basal lobe, obliquely ridged upon the under surface. . Maxille, very large and prominent, longer than the mandibles ; with palpi of three joints, the first and second short, cylindrical, the third as long as the first and second united, more slender, flat, and divided nearly to the base into two superimposed lobes bearing papille ; maxillary lobe 1878. ] 667 [Hubbard, divided anteriorly by a deep notch into two portions, the apical, smaller and narrower than the basal, blade-shaped, tipped with a long slender spine, and bearing four long and stout teeth projecting at right angles to the lobe, like the blades of a half-opened penknife ; the basal portion with two rows of teeth on the border, and a slender tooth and bristle at the apex. Labium consisting firstly, of an elongated, triangular mentum, with the apex thickened in aconical protuberance, bearing a pair of bristles near the middle, and another pair upon the thickened tip ; secondly, of a transverse palpiger, bearing small fleshy palpi of two subequal joints, and its anterior border prolonged between them in a conical projection; thirdly, of an elongated, convex, corneous ligula, enlarged anteriorly, with straight borders and a pair of bristles near the tip. Behind and above the mentum and plainly seen through the transparent tissues, is a broadly triangular, horny piece, the base of which extends between the hinges of the mandi- bles, and the apex reaches as far as the middle of the ligula; upon the upper surface oblique grooves on each side correspond with the ridges upon the basal lobes of the mandibles, into which they lock when the man- dibles are closed.* Thoracic segments slightly thicker than the abdomen, the first longer, the two following subequal in length. Abdomen cylindrical or slightly depressed, of nine segments, the first eight subequal, transverse, each with a few long bristles, the ninth conical, scatteringly covered with long bristles, terminating abruptly in-two minute toothed appendages, one proceeding from the dorsal surface, and arching downwards, the other from the ventral surface, curving upwards, and re- sembling two hands with partly extended fingers, having the palms turned towards each other. The upper and longer appendage appears to be tubular for one-third of its length from the base, the remainder is con- cave beneath, and terminates in two terminal and six lateral teeth, directed downwards, their bases forming longitudinal ridges on the concave under surface. The lower appendage is shorter, more strongly curved, and in the opposite direction, concave above, expanded into a palm at the end, with eight teeth as in the preceding; the concave upper surface is distinctly denticulate. The larva lives in damp situations, in the soft, crumbling wood of old oak logs, which have become entirely disintegrated and colored dark red, probably by a microscopic fungus. A number of larve, pupe, and imagos were found together in a small portion of such a log on August 17th, 1874, at Detroit, Michigan. As Dr. LeConte has placed this insect in the family Lymexylide, it will be interesting to compare its larva with that of Hylecwtus lugubris Say, specimens of which are before me. The larvee of Hylecwtuws were taken from cylindrical burrows in the solid wood of the American linden. It * This piece and the mandibles, the forms and relative positions of which are shown in fig. 9 of the plate, though very conspicuous in dissections under the microscope. are omitted in fig. 5 in order to avoid obscuring overlying parts. Hubbarda.] 668 [April 18, has a cylindrical body of twelve segments; a globular head, with two large ocelli, which are, however, covered by the epidermis; the first tho- racic segment is enlarged, and partly covers the head, like a hood ; the three thoracic segments bear well-developed legs ; and the abdomen termi- nates in a long tapering style, toothed and concave on the upper surface, and turning upwards at the end ; the stigmata are large and in their normal positions, one pair beneath, on the thorax, and eight pairs on the sides of the abdominal segments. The antenne are four-jointed, exceedingly minute and stout, and, as in Micromalthus, have the third joint lobed beneath, an apical spine, and oc- cupy similar positions on the anterior angles of the head; the maxille also have the lobe divided into an upper and lower portion, although the sepa- ration is not very distinct, and appears under the lens as a corneous line, the spines upon the lobe are slender and not markedly different upon the two portions. The labrum and labium are stout and thick, but do not pre- sent important structural differences from the same parts in Micromalthus. The mandibles are simple or slightly notched, the basal lobes not promi- nent, but finely ridged, and closing upon a triangular corneous piece which lies above the mentum. All the parts of the mouth in Hylecwtus are smaller, stouter, and simpler in their structural details than the correspond- ing organs in Micromalthus, differences which perhaps have some relation to the harder material in which the former lives. Notwithstanding the striking difference in their external forms, the important structural analo- gies between the antennz and mouth parts, seem to indicate a relationship between these two larval forms.
