This aud the preceding species belong to a group of African 

 CaUichrominai, distinguished by their greatly elongated uan'ow 

 form, and the long hind legs, of which the femora are but 

 shghtly thickened. The middle femora are also less clavate and 

 pedunculate than in the rest of the geniis. These characters, 

 however, shade off Ijy insensible gradations (C disroidali-s', 

 ch/'jjsaspis) into the typical forms.
