The genus Catacroptera differs from all the species of Precis in the i)atch 

 of modiiied scales on the underside of the forewing near the base being much 

 larger, extending beyond SM-. 



C. cloanthe, the only species of the genns, consists of a West African 

 subspecies, and an East and .South African one, each of which appears again in 

 one form with dark underside and another with brighter underside, the two 

 forms corresponding to the " wet and dry phases " of Precis. In the form 

 with dark underside, the " dry phase," the distal marginal area of the wings, on 

 the upperside, is more or less conspicuously shaded with tawny brown. The 

 subspecies inhabiting South and East Africa is

The individuals from Somaliland and Abyssinia liolong to this subspecies, 

 and Neumann obtained three S S and two ? ? at : Lake Zuai, 24. si. 00 ; Lake 

 Abassi, 4. & 0. xii. 00 ; Alata, Sidamo, 13. xii. 00 ; Djiren, Djimma, 2". iii. 01. 



Of these specimens one from L. Abassi belongs to the " dry pliase," the 

 others being intermediate. 



Tiie individuals from West Africa differ from cloanthe cloantln' in the marginal 



and admarginal black lines of the forewing, above, being heavier, not obsolescent, 



and in the series of eye-spots of the hindwing, on the. upperside, being proximally 



and distally accompanied by a crenate black line, which is heavier than in the 



corresponding " phases " and sexes of cl. cloanthe. We name the West African 



subspecies
