H amcenus, as here restricted, may be described as a form 

 of H. plaffiocephalus, Er., with the antennal joints 3 and 4 

 widened, and with an elongate shining black area beneath, 

 and 6-11 sharply nigro-maculate at the tip, in the c? ; ^^^^ 

 $ also has the onter joints similarly maculate. Nine cJ S' 

 from various localities are before me, two of them having 

 an additional dark mark at the sides of the prothorax. The 

 specimens from Bothaville ( c? ? ), subsequently referred by 

 Gorliam^ to H. amcenus, probably belong to H. dentati- 

 thorax, Pic.
