half lonjier than wide, somewhat ol)li<iviely pointed, bastil joints eiich with a 

 few very long erect black setai near the apex. Prothorax one-half wider than 

 long, the sides evenly and strongly arcuate, becoming parallel at the base; apex 

 three-fifths as wide as the base, the bas;il angles gradually and rather strongly 

 prominent jjosteriorly but (juite distinctly rounded. Scutellum triangular 

 with the sides straight and the ai)ex only slightly blunt. Elj/lra not (juite as 

 long as wide, the suture distinctly longer than tlie prothorax, evidently nar- 

 rowed behind from the base, with tlie sides evenly and feebly arcuate; apex 

 broadly, angularly emarginate, the outer apical angles rather liroadly rounded; 

 disk somewhat finely imbricate, the imbrications relatively very coarsely re- 

 ticulate. Abdomen gradually tapering, bristling at the sides with long erect 

 l)lack setic throughout the length. Length 1. ■2.5-1.35 mm.; width 0.>^o mm. 



North C-arolina (Asheville). 



The epipleur£fi are narrow, becoming obsolete before the 

 rounded apical angles of the elytra and gradually vertical exter- 

 nall}' toward base ; they are glabrous toward base but distinctlj' 

 pubescent posteriorly. The epistomal suture is rather abruptly 

 and posteriorly sinuate in the middle. The sixth ventral segment 

 of the male has a large deep and triangular emargination. occupy- 

 ing almost the entire apex, scarcely more than one-half wider than 

 deep and with the angle slightly rounded. Numerous specimens 

 are before me differing scarcely at all in size. 



16. C. SUbtilis n. sp. — (Oblong-oval, strongly convex, feebly shining, pale 

 castaneo -testaceous, with the elytra darker; legs, basal parts and apex of the 

 antenna" paler; pubescence moderately short and dense, dark, the sculpture of 

 the anterior parts very feel)le. Haul fully one-half as wide as the prothorax, 

 the antenn;e about extending to the base of the latter, feebly iucrassate, with 

 the tenth joint somewhat longer than wide; epistomal suture broadly and pos- 

 teriorly sinuate almost throughout the width. Prothorax fully three-fifths 

 wider than long, the apex three-fifths as wide as the base; sides evenly and 

 strongly arcuate, becoming parallel at the basal angles, which are only moder- 

 ately prominent posteriorly and distinctly rounded. Elytra one-fourth wider 

 tlian long, the suture e(jual in length to the prothorax, the sides somewhat 

 convergent and feebly arcuate from the base; external apical angles broadly 

 rounded; disk rather closely imbricate, the imbrications freijuently crossed by 

 a fine median line. Ahdotnen with long coarse and bristling l)lack seta> at the 

 sides from apex to base. Lengtli l.'J.Vl.S.') mm. : width 0.^ mm. 



Texas (Austin). 



The male has a large deep and narrowly parabolic emargination 

 occupying practically the entire apex of the sixth ventral seg- 

 ment, and distinctly less than twice as wide as deep. The epipleu- 

 rne are nearl}' as in debilis, but attain the rounded apical angles. 



This species is closely allied to dehihs. but may be distinguished
