Care is necessary in order not to confuse this species with the 

 foregoing, from which it may be distinguished by the paler coloration 

 of the proximal two-thirds of the costal border of the wings, and 

 the more slender first joint of the antennae. From a study of the 

 material at present available it is evident that C. distinctipennis 

 has a wide distribution in Tropical Africa, since on the western 

 side of the continent it has been found in Gambia, Ashanti, Northern 

 Nigeria, and French Congo, while it also occurs in Abyssinia and 

 Uganda. The species is represented in the National Collection 

 by seventeen females, the localities, etc., of which are as follows : 

 Bantonding, Upper Gambia, March, 1908 (Dr. T. Hood) ; Navarro,
