Hah. Cameroons : Mimdame (E. Eohdc). In the 

 British Museum and German Entomological National 

 Museum. 



This is closely related to P. gamhiensis, Westw., but 

 both sexes are more shining, more strongly punctured on 

 the head and thorax, and without smooth longitudinal 

 lines upon the elytra. The male is a little broader, and 

 the front tibiae, which in P. gamhiensis have only two 

 front teeth, are distinctly tridentate.

Hah. Cameroons : Mundame (A'. Rohde).

 National Museum. 



It is rather darker-coloured and less broad than the 

 previous species, with the head less punctured and the 

 elytra more coarsely punctured, with distinct longitudinal 

 lines, which are slightly elevated in front. It is exceedingly 

 like P. masJiunus, but a little less shining, less coarsely 

 punctured, and the front tibia of the male has only two 

 sharp teeth, as in P. gamhiensis, Westw.
