Soutli African Coleopterous Fauna. 305 



This species is allied to P. capucina, Fahr, but the head and pro- 

 thorax are not raised so as to form a kind of hood as in the latter, 

 in which the elytra bear no traces of a dorsal costa, which is very 

 conspicuous in P. umtalina, but the vestiture of the two species is 

 very much alike.
