and one from Old Calabar, in addition to the absence of this spot, 

 have the subapical ochreous band narrower thau in the specimen 

 before me ; the only difficulty is that a female in the Museum from 

 Old Calabar corresponds far better with the Cameroons type than 

 with Hewitson's males, none of which differ strikingly from the 

 Congo male. As it is hardly liicely that the differences between the 

 Old Calabar and Cameroons males can be constant, though well 

 marked in the specimens in the Museum, I have regarded them as 

 the residt of individual variation.

15. EUPH^DRA JOHNSTONI, Sp. n. 



S . Allied to E. losinga and luperea ; nearest to the former, from 

 which it differs as follows : primaries above with the costa, two 

 large spots in the cell, aad the apical half black, external angle 

 suffused witii purple ; oblique ochreous subapical belt longer and 

 broader ; secondaries with a broad external belt of purple, from 

 subcostal vein almost to anal angle, enclosing four large oval dark 

 copper-brown spots : all the wings below with subapical white band, 

 that of primaries representing the ochreous baud of the upper 

 surface, that of secondaries more transverse and tapering to below 

 the third median branch ; three black spots placed in the form of 

 a triangle, and a terminal transverse black dash in all the discoidal 

 cells. Expanse of wings 90 millim. 



One male. 



I have been unable to find a description of this very handsome 

 species, which I have therefore been obliged to name.
