sixth equal and fully as long as wide ; seventh ^ wider, cylindric and 

 rougher, slightly longer than wide ; eighth not more than % wider than the 

 seventh, fully as long as wide or a little longer ; ninth and tenth equal in 

 width and about ,y wider than the eighth, very nearly as long as wide and 

 almost }4 wider than long respectively ; eleventh somewhat thicker, long, very 

 obliquely and gradually pointed and rather longer than the two preceding. 

 Prothorax conic with very feebly arcuate sides, as long as wide ; apex rather 

 more than }4 ^s wide as the base, the latter fully 3si wider than the head ; 

 surface with two approximate and distinct transverse impressions near the 

 base. Elytra % longer than wide, distinctly more than twice as long as the 

 prothorax and % wider, gradually narrowly parabolic at apex, widest before 

 the middle, the sides very eA'enly arcuate throughout ; humeral plica long, 

 strong and conspicuous, the impression large and deep ; fovese distinct ; sub- 

 sutural impressions rather well marked, the suture narrowly beaded basally, 

 the bead expanded at base. Abdomen with the first segment overlapping the 

 next and having a short fringe of hairs and scattered membranous scales. 

 Legs well developed, the anterior femora rather strongly, the four posterior 

 much less strongly, clavate. Length 1.3 mm. ; width 0.6 mm. 



Pennsylvania (Westmoreland Co.). Mr. Schmitt. 



The male described above has the spur of the hind tibiae slen- 

 der, perfectly straight and simple, oblique in direction, being 

 bent abruptly at base and is notably long, being rather more than 

 f as long as the tarsus. The species may be readily known not 

 only by this character, but by its rather elongate elytra, strongly 

 modified at the humeri, long pubescence, pale coloration and 

 other characters. The last two segments of the abdomen are 

 still paler as usual. Several specimens. 



74. C. lacunosum n. sp. — Eather stout, polished, impunctate, very 

 dark piceo-rufous, the entire elytra slightly paler and dark rufous ; antennae 

 dark red-brown, the legs rather paler, rufous ; pubescence moderately abun- 

 dant, long coarse erect and pale on the elytra. Head well developed, slightly 

 wider than long, subcircular behind, the eyes rather large, convex and promi- 

 nent ; antennal prominences almost obsolete, the front not definitely impressed; 

 clypeus even, the apex rectilinearly transverse, without trace of median pro- 

 jection. Antennas only slightly longer than the head and prothorax, rather 

 slender but with the club pronounced and rather abrupt ; second joint feebly 

 obconic, nearly }4 longer than wide, as long as the next two and thicker ; 

 three to six equal in width, not quite as long as wide, the fifth as long as 

 wide ; seventh }£ wider than the sixth, not as long as wide ; eighth % wider 

 than the seventh, ^ wider than long ; ninth ^ wider than the preceding, 

 broadly spherical in apical half, % wider than long, the tenth almost similar 

 but just visibly wider and nearly }4 wider than long ; eleventh paler, slightly 

 thicker, as long as the two preceding, very obliquely pointed at apex. 

 Prothorax rather small, distinctly shorter than wide, strongly conic with the 

 sides feebly arcuate ; apex about }4 ^s wide as the base, which is nearly 3^
