says in 1894 1 : "I am quite satisfied that B. gidica and B. abys- 

 sinica can not be regarded as distinct species" and in 1898 2 : 

 "I may begin by stating emphatically that gidica is not the wet 

 season form of abyssinica" .

 Zeraf, Kaka; February 24—28. 



The males are very small, only measuring 30 — 33 mm. be- 

 tween the apices of fore wings; the females have an expanse of 

 35 — 42 mm. The black markings are in both sexes more reduced 

 than in the typical form and the ground-colour is purer white.

 Eenk; February 12—20. 



20. Teracolus amelia Lucas. 19. — Kaka; February 28. 

 Undoubtedly the dry season form; unfortunately I am not 



able to compare it with a female of the wet-season form men- 

 tioned by Butler in An. N. H. (6) 20, p. 506 (1897).

23. Teracolus phlegyas Butl. 



var. hib. j alone Butl. 1 d% 1 9. — Abba-Island, 12 th Febr.; 

 to the South of Kaka, 28 th Febr. 



The female (Fig. 2) taken near Kaka comes nearest to the 

 form called coliagenes Butl., but has the ground-colour of the 

 upper side pure white, and on the underside the apices of the 

 fore wings and the hind wings are of a pale reddish grey, the 

 latter have, as in the male, a distinct discal row of blackish spots.
