Zeritis hicolor, sp. u. 



I have ventured to describe this species, as there are six 

 specimens, all alike, in Mr. Crowley's collection, which has at 

 the same time eight specimens of Z. leonina^ E. M. Sharpc. I 

 therefore think that there can be no doubt of the distinctness 

 of Z. hicolor from Z. leonina. 



The underside resembles that of Z. leonina very closely, 

 but the upperside is decidedly different, especially as regards 

 the fore wing. 



Fore wing entirely black, with the exception of a very 

 minute spot or streak of orange-rufous on the inner margin 

 nearest to the hind margin. 



Hind wing : base shaded with black ; costa and part of hind 

 margin broadly marked with black, which gradually decreases 

 and terminates at the end of the second median nervule. The 

 rest of the wing is bright orange-rufous, which fades to a 

 pale yellow on the inner margins. 



Exp. 1*2 inch.

Mr. Walker obtained two specimens from Perim Island, at 

 the entrance of the Red Sea. Ehrenberg's type w^as from 

 Arkiko, on the coast of Abyssinia. B. dimidiatus was cap- 

 tured at Tes, in Arabia. 



Mr. Walker's specimens are undoubtedly co-specific with 

 the type of P. scaber^ since they closely agree with Ehrenberg's 

 admirable figure of his species. 



M. Simon describes dimidiatus as having the tail fere 

 parallela and the vesicle suhter valde et grosse tuherculata — 

 two phrases which certainly do not apply either to the figure 

 of scaher or to my specimens of this species. In the figure
