by its narrower form and decidedl}' shorter elytra ; the first two 

 joints of the antennte bear long black apical setie as in dehilis^ 

 but the tip of the abdomen is paler and more acute in subtilis.

Rather narrowly suboval, convex, shining, castaneous, the an- 

 tennae somewhat short and incrassate, with the penultimate joint 

 transverse. Prothorax one-half wider than long, the sides arcu- 

 ate, becoming parallel toward base, the basal angles obliquely and 

 moderatel}^ prominent posteriorly and onl}^ slightly blunt ; disk 

 ver3' coarsely but feebl}- reticulate. Elytra short, nearly one-half 

 wider than long, narrowed behind, distinctly shorter than the 

 prothorax, with the external angles at apex but little rounded and 

 the disk very coarsely imbricate. Abdomen rapidly tapering, the 

 long black seta? apparently obsolete toward base. Length 1.15 

 mm.; width 0.7 mm. 



North Carolina. This is the smallest species of the genus, and 

 is very distinct from the two preceding in its coarse imbricate 

 sculpture and very short elj'tra. The epipleurre are narrow, entire, 

 becoming gradually and moderatelj^ deeply vertical externally to- 

 ward base, and are slightl}- pubescent posteriorly. The male has 

 a large triangular emargination at the apex of the sixth ventral, 

 the notch more than twice as wide as deep and with the angle 

 narrowly rounded. 



18. C. scripta Horn— Trans. Am. Ent. Boc, YI., p. 112. 



Stout and suboval, very strongly convex, polished, rather 

 sparsely clothed with coarse fulvo-cinereous hairs ; body pale 

 brownish-testaceous in color throughout, the pronotum some- 

 times slightl}' clouded and the elytra with a blackish nubilate de- 

 sign. Length 1.3-1.5 mm.; width 0.95-1.0 mm. 



Rhode Island and New York. This species can be instantly 

 recognized by the long black sette at the sides of the elytra, 

 the setas being also more developed on the abdomen at the 

 sides throughout than in any other member of the genus, and 

 there are, besides, four series along the under surface of the 

 abdomen. The epipleurje are narrow, entire, and only slightlv 

 vertical externall}- toward base, but the3' differ from the forms 

 prevailing in the preceding section of the genus in being com- 

 pletely glabrous. The elytral punctures are rather sparse and 

 distinct, feebly asperate, each with two short divergent lines,
