Clypeus broadly rounded in the middle at the apex and 

 densely covered with silvery pubeseence. Mesonotum and 

 seutellum rather strongly punctured. Metanotal area 

 obliquely striated, the rest strongly and rather irregularly 

 punctured. Propleuraj strongly obliquely striated; the 

 mesopleurae (except at the base) strongly and uniformly punc- 

 tured. The base of the metapleurse smooth, irregularly and 

 finely striated above and below, the apex rugose. Pygidium 

 rather strongly, but not very closely punctured. 



The obliquely striated metanotal area brings this species 

 into Bingham's section C. b near to C. Elizabethce.
