The specimen described was received with Capt. Kerre- 

 nians' collection, from Chevrolat's collection, and was 

 labelled " t'/ascmfa, Waterh." It differs from that species 

 in its dark colour, smaller size, longer scutellum, less costate 

 elytra, totally different serration of the apex, and in the 

 colour of the abdomen. 



M. Tiidry has desc.ibed (Bull. !Soc. Ent. Fr. 1904, p. 75) 

 a species (C. ruat/eti) closely allied to this. He says : " il 

 se di.stingue de 0. bijasciata, Wat., par sa faille plus grande 

 et son abdomen de n.eme couleur que le rest du corps. ^^
