.gth 12 lines. ^Elongate; entirely of a dull black, with a slightly bluish 
head and prothorax impunctate ; on the latter a transverse, sinuous xm^ 
. at the middle, near the base, and one or two others smaller, near the hmd

res, which nick their sides ; the intervals -save the first -are na.-row, con-

The majority of the above characters were pointed out by 
ordaire (Genera, v, p. 378, note) when stating the advisability ot 
.ting it into a distinct genus. The more convex form and the elytra 
dually widened from the base to beyond the middle and abrupt y 
livons behind, give quite a different facies to that of Zophobas, to 
.ch, however, the present insect must be closely related notwith-
