Congo Free State, 1904 {Drs. Dutton, Todd, aid Christy). 



In some respects, such as coloration of body and width of 

 front, this species resembles HcEinatopota lonrja, Ricardo, the 

 type of which is from the Nyasaland Protectorate ; apart 

 from its much smaller size, however, H. vexans may be 

 d stlnguished, inter alia, by the fact that in the win^- the 

 stigma is not conspicuous, being lost in the dark colour of 

 the brown blotcii below it, and by the absence of a second 

 light baud on the hind tibia.
