 plateau at Kithungulu, Konu, Ukikuya, Tana river-basin. 



Two forms of this species w'ere obtained, the first only differing 

 from the southern type in its usually slightly superior size ; the 

 male with slightly narrower oblique black bar at end of cell, larger 

 white hastate spots on the apical black area, and primrose- 

 whitish colouring of the under surface of the secondaries. The 

 second form, however, has the black discocellular bar reduced to a 

 spot at the inferior angle of the cell in the male, but in the female 

 only slightly narrower than iu the first form ; on the under surface 

 the veins are more heavily denned and sometimes quite black. It 

 is useless to attempt to separate the latter from B. zochalia ; and as 

 it shows a decided tendency in the direction of B. craivshayi, it is 

 within the range of possibility that, as the fauna of Africa becomes 

 better known, a series of gradations between B. zochalia and 

 that apparently distinct form will be discovered. Indeed, after 

 seeing the series of grades between typical B. infida and B. severina 

 nothing will surprise me in the way of linking the African species 

 of Belenois. I am quite satisfied that B. gidica and B. abyssinica 

 cannot be regarded as distinct species.
