Diplotropis castanea, Fahr., 

 Insect. Caffr., ii., p. 106. 



Head and prothorax piceous, elytra piceous turning occasionally 

 to dark brown ; clypeus shaped like that of C. nigrina, 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 genae project conspicuously, the clypeal carina is very 

 sharp, the clypeus is deeply punctate, and the head and genae sub- 

 rugose ; antennae reddish, club long, 7-jointed, 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. 



Length 8 mm. ; width 4 mm.
