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

 of H. plagiocephalus , Er., -with the anteimal joints 3 and 4 

 widened, and with an elongate shining black area beneath, 

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



$ also has the onter joints similarly maculate. Nine ^ ^ 

 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 

 Gorhain ^ to H. amoenus, probabl}' belong to H. dentati- 

 thorax, Pic.
