IV.—Deseriptions of two new Species of Coleoptera from Angola. 
By the Bardo vo CasrELLo DE Patva, Professdr de Botan- 
nica na Academia Polytechnica do Porto. 
Tue following two species of Coleoptera were discovered in An- 
gola by my learned friend Dr. Frederic Welwitsch; and I 
have great pleasure in naming one of them after him, and the 
_other after M. Sabin Berthelot, the French consul at Teneriffe
