6. C. velocipes n. sp. — Moderately stout, strongly convex, feel>ly shin- 

 ing, blaokish, the basal niarjiins of the pronotuni and elytra unevenly and 

 feebly suffused with a paler reddish tint: abdomen paler, red-brown through- 

 out; legs and antenna- rufo-testaeeous, the latter paler and more yellowish 

 toward base and at the eleventh joint; jjubescence very fine, dense and plum- 

 beo-cinereous throughout, the punctures minute and scarcely visible. Head 

 small, distinctly less than one-half as wide as the prothorax, the epistoma 

 paler and with more distinct punctulation and reticulation; antenna; rather 

 long, evenly and gradually incrassate througli the last six or seven joints; the 

 ninth scarcely as long as wide, the tenth perceptibly wider than long, eleventh 

 rather short, somewhat rapidly, obliquely and acutely pointed at apex. 

 Prothorax nearly three-fifths wider than long, the apex but slightly more than 

 one-half as Avide as the base, the sides evenly and strongly arcuate becoming 

 l)arallel toward base, the basal angles gradually and only moderately promi- 

 nent posteriorly and distinctly rounded. Eli/tra nearly one-fourth wider than 

 long, not at all longer than the i)rothorax, the sides distinctly convergent but 

 only very slightly arcuate from base to apex; disk convex, moderately finely 

 imbric<ate. Abdomen very evenly and gradually tapering from base to apex, 

 the erect black seta; long and distinct at the sides throughout, but, as usual, 

 ICvSs numerous toward base. Length 2.0 mm. ; Avidth 1.4 mm. 



New York (near the city); New Jersey; Virginia (Fredericks- 

 burg). 



This distinct species may be readily known by the ventral 

 sexual characters of the male, the long black and bristling setiie 

 being ver}-^ numerous throughout, except broadly along the 

 median line where the ordinary short pale pubescence becomes 

 longer, more erect and conspicuous. The sixth ventral has a 

 triangular nick in median third at apex, the notch nearly three 

 times as wide as deep and with the angle not rounded, the apex 

 of the fifth segment arcuately sinuate in the middle. The epi- 

 pleuriv are wide and l>ecome gradually nearly glabrous toward 

 base. This species may be distinguished from imhricata l»y its 

 shorter elytra and long black bristles toward the base of the 

 abdomen. 



7. C. castaiiea Horn — Trans. Am. Ent. Soc, VI.. p. Ill; iicntdiniulitm 

 Fvl., i. litt. 



Rather stout, strongly convex, pale brownish-testaceous in 

 color throughout, minutely and densely pubescent, the punctures 

 scarcely visible. Length 1.7-1.9 mm.; width 1.1-1.3 mm. 



Coast regions of California from Humboldt to Los Angeles ; I 

 obtained three specimens also at Lake Tahoe, which represent a 

 slightly smaller and narrower variety. The male has a rounded
