rounded and narrowed in front ; hind angles acute biit not pro- 

 duced ; surface entirely impunctate. Scutellum ratlier long and 

 pointed. Elytra with the basal margin carinate, the punctures 

 stronger at base than posteriorly, each row commencing with a

Hah. Peru. 



Of somewhat Monachus-M^Q shape and well distinguished by 

 the entirely black coloration, finely granulate head, &c. The

Subcylindrical aiid parallel. Head pale green, the vertex with 

 a deep depression and a few fine punctures only ; clypeus distinctly 

 separated from the face, more distinctly punctured, margined 

 with obscure flavous ; eyes broadly and subquadrately emarginate ;

Hab. Jalahy, Prov. Goyaz, Brazil. 



Much distinguished by its green and flavous coloration, rare 

 amongst the numerous members of this group, but evidently allied 

 to C.aUiaceus Kirsch, from Peru, in coloration, but in that species 

 the head is flavous and the elytra are banded.

 much shorter than the following ones, these scarcety thicker. 

 Thorax about one half broader than long, much naiTowed in front, 

 lateral margins oblique and straight ; surface impunctate, the
