Numerous examples, including seven mal( s, two of which 

 are from Rhodesia. These males differ from the same sex 

 of the Usagara insect here referred to H. spectahilis, Ancey, 

 in having the antennse more strongly serrate, the prothorax 

 more rounded at the sides, and the lamella on the upper 

 inner edge of the intermediate tibise broader and more 

 prominent than the lower one, the inner margin only of the 

 former testaceous.

(J . Very like, and possibly a form of, H. bilamellatus, but 

 differing chiefly in the development of the intermediate 

 tibige (PI. VIII. fig. 14), the lower lamella of which is larger 

 and more angular, and the upper one narrow, mor or less 

 angulate proximally, and sinuato-plicate and deeply sulcata 

 above ; the antennae, too, are a little longer, and ha\e the 

 apical joint strongly curved and more elongate.
