Coleopterological Notices, V. "489 



Of americanus Schauf. I have before me a single male from Illi- 

 nois; it is blackish in color throughout and unusually narrow and 

 elongate ; the third palpal joint is evidently shorter than the fourth. 



C comes n. sp. — Moderately narrow and convex, polished, subimpunc- 

 tate, dark rufo-testaceous, the abdomen piceous ; pubescence sparse but very 

 long, erect, the hairs of the elytra about one-third as long as the prothorax. 

 Head longer than wide, as long as the prothorax but much narrower ; eyes 

 large, prominent, nearly at the base ; antennal tubercles convex ; vertexal 

 fovese deep, perforate, on the sloping sides near the eye ; subfrontal spicule 

 midway between fovea and tubercle, small ; palpi long, third and fourth 

 joints beset with long erect setae, the former much the shorter ; antennae one- 

 half as long as the body, the club not quite as long as the funicle, first joint 

 stout, longer than wide, with a large oval area at base which is flattened and 

 well defined above and beneath, one to three decreasing feebly in thickness, 

 three to seven longer than wide, eighth wider than long, ninth and tenth 

 abruptly much wider, trapezoidal, eleventh as long as the preceding three. 

 Prothorax convex, nearly as long as wide, widest and strongly rounded at the 

 middle ; sides thence strongly convergent to the apex which is three-fifths as 

 wide as the base ; near the basal margin a few small feeble impressions and 

 on each side before the base a larger fovea. Elytra about as long as wide, as 

 long as the head and prothorax, nearly twice as wide as the latter; humeri 

 evident, widely exposed at base, the humeral width fully four-fifths of the 

 subapical ; impressed discal line extending to the middle. Abdomen scarcely 

 as wide as the elytra and much shorter, the first visible dorsal distinctly 

 longer than the second ; border moderate. Length 1.6 mm. ; width 0.7 mm. 



Florida. 



The male, from which the description is taken, has a short stout 

 erect spine at the base of the anterior and posterior trochanters, the 

 intermediate simple. The metasternum is tumid, the tumidity bear- 

 ing two rather distant short erect and acute spines, arranged trans- 

 versely just before the middle of the metasternal length, the poste- 

 rior declivity broadly feebly and longitudinally impressed to the 

 intercoxal sinuation. First and second ventrals not impressed, the 

 sixth with a small deep lunate impression at apex, not extending 

 beyond the middle of the segment and bordering the small flat ven- 

 tral pygidium. 



This species differs from ludovicianus Brend. in its smaller size 

 and longer pubescence. 



C. crinifer n. sp. — Rather convex, polished, dark rufo-testaceous through- 

 out, often paler from immaturity ; integuments subimpunctate ; pubescence 

 long, sparse, erect and bristling, the hairs of the elytra nearly one-third as 

 long as the prothorax. Head scarcely as long as the prothorax and about
