This and the preceding species belong to a group o£ African 

 Callichrominm, distinguished by their greatly elongated narrow 

 form, and the long hind legs, of which the femora are l)ut 

 slightly thickened. • The middle femora are also less clavato and 

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

 however, shade off by insensible gradations (C. discindalis, 

 chriisaspis) into the typical forms.
