 strougly and roundly declivous to apex; sides suLparallel towards 

 base; apex widely rounded; strife 4-7 not reaching base, seventh

A very distinct species, differing from all others with the 

 metepisterna short, by its impunctate mes- and metepisterna, 

 and ventral segments; from other species, except C. impar SI., 

 it differs by size smaller, elytra more strongl}^ striate, etc.; from 

 C. impar it differs by its short, wide, more convex form(both 

 prothorax and elytra much shorter), etc.

I have inspected one type-specimen(9) of C. nitidus Macl., in 

 the Macleay Museum. I consider, from Chaudoir's description, 

 that C. oviformis Chaud., is synonymous with it. G. nitidus 

 has, from type, the metepisterna short, impunctate; mesepisterna 

 impunctate, except at bottom of femoral channel. 



CoPTOCARPUs GiBBUS Chaudoir. 



Ann. Soc. Ent. Fr., 1882 (6), p.511. 



I have identified this species from Chaudoir's description. 

 The female is very convex, the male less so. It is variable in 

 size, length 10-13, breadth 4-1-5-3 mm.
