There is alarge, distinct, outwardly curved impression at each side ofthe disk, 
extending from near the middle to the basal margin ; the scutellum is 
transversely curvilinearly triangular and closely punctured ; the elytra are 
distinctly convex behind the middle, and are consequently more abruptly 
declivous behind than in ©. opacula ; the base is feebly sinuately truncated, 
and between it and the base of the prothorax (and the hind angles of the 
latter, which repose on the shoulders) there is a decided open space, as in 
C. opacula ; the lateral margins are expanded (but less broadly so than in 
the preceding species) and concave, and there is the row of rugged fovee 
just within this margin, as in C. opacula; the disks of the elytra also 
present traces of numerous narrow longitudinal coste ; the under side and 
legs are of a deep brownish-black, shining ; the antenne, tarsi, and palpi 
are reddish-brown. 
Length 7} lines; elytra, width 82 lines.

Very close to C. opacula, and difficult intelligibly to define in what ib 
differs from that species ; it is, however, distinctly narrower or oblong-oval, 
usually smaller, paler, more convex, the base of the prothorax more closely 
applied to the base of the elytra, distinctly more shining, the punctuation 
etc., on the elytra coarser, more confluent and confused, somewhat rug- 
gedly so at the sides; the sides of the prothorax more rounded, more 
incurved at the base, the median basal lobe more prominent; the base, 
consequently, has not that appearance of being bisinuate-emarginate as is 
the case in C. opacula, 
Head closely punctured, the punctures coarsest and somewhat confluent 
on the front, between the eyes, where there are also usually two more oF 
less marked foveate depressions; prothorax more or less strongly trans- 
verse; sides more or less regularly rounded, more narrowed in front than 
behind, always distinctly and more or less sinuously incurved before the 
hind angles; apex deeply arcuate-emarginate, the angles prominent, 
subacute, and usually directed forwards; base bisinuate, the angles more 
or less prominent and acute, reposing on the shoulders of the elytra, and 
directed backwards; disk moderately convex, very closely (save on the 
centre) punctured, the interstices a little elevated, and more or less reticu- 
late, at the sides ; a transverse depression subparallel and near to the base, 
and an angulate fovea at each side, close to the basal margin (as in Fem., ? of 
C. opacula); sides moderately expanded, the edges unequally (not uni- 
formly) thickened ; scutellum as in C. opacula: elytra oblong-oval, base 
sinuate-truncated ; disk moderately convex, closely and more or less con-
