This extraordinary and beautiful little Phanaeus was taken in 

 one exaraple only, by my friend Dr. Spruce at Canelos on the Pas-

Perty states that bis sjiecies was taken in Southern Brazil. I 

 believe this locality is erroneous like many otbers given by this 

 author. The species is found at niost places on the banks of the 

 Upper Amazons, whence Spix and Martins obtained it. It is also 

 found at Cayenne. It belongs to the group of P. carnifex^ the J 

 having the surface of the prothorax flattened. The frontal hörn is 

 Wide and plane (in front) at the base, and becomes suddenly uar- 

 rowed betöre the nüddle. 



Taken by myself at Ega and S. Paulo, Upper Amazons.

Mac Leay's description of this species like that of most of the 

 Copridae he attempted, is füll of errors and misconceptions. In 

 describiug the $ , he clearly describes the head of a S and the 

 thorax of a J. His description of the % is certainly not that of 

 a ? at all but of an undeveloped J . The two forms most pro- 

 bably belong to separate species. In such a case, I think it is 

 better for the interest of science to set aside his description all 

 together.

Mac Leay in this species also describes an undeveloped t for 

 the $ ; in which mistake he is foUowed by Castelnau. I think I
