DIPLOTROPIS CASTANEA, Fahr., 
Insect. Caffr., 11., p. 106. 
Head and prothorax piceous, elytra piceous turning occasionally 
to dark brown; clypeus shaped like that of C. nzgrina, but much 
more deeply cleft in the centre and bi-lobate on that account, this 
median incision does not, however, reach the strongly arcuate clypeal 
suture, the genz project conspicuously, the clypeal carina is very 
sharp, the clypeus is deeply punctate, and the head and gene sub- 
rugose ; antenne reddish, club long, 7-jomted, but with the inner 
joint only one-fourth as long as the others; prothorax and elytra 
with a fringe of spaced, seriate hairs, the former is deeply but not 
closely punctured, the punctures are much deeper and slightly more 
closely set on the elytra, the pygidium, abdomen, and pectus are 
pubescent. Female unknown.
