Africa. The spots in question are in B. hoycli, as in the British 

 Museum specimens of B. g'dtzius from the localities last named, 

 larger, closer together, more conical, and less quadrate than in 

 individuals from West or South Africa, though in dry-season 

 forms from Natal and East Central Africa an approach is made to 

 the Socotran condition. The dark submarginal band of the hind 

 wing in B. hoycli is broader than in most specimens of B. cjotzius 

 from E. and S. Africa, whether " wet" or •' dry" (the narrower 

 band belonging generally to the "dry" form). It is much 

 broader than in the specimens of B.gotzius from Somaliland, Aden, 

 and the Gralla country above referred to, but not, perhaps, much 

 broader on the average than in the female specimens from 

 Abyssinia. 



The present examples of B. hoydi, like Prof. B. Balfour's pair, 

 are all dry-season forms. In at least two of the seven (both 

 males), as also in both Prof. Balfour's specimens, the whitish 

 internervular spots on the dark submarginal band of the hind- wing 

 underside have disappeared, and in one of these the patches of 

 grouud-colour immediately adjacent to the pale median band are 

 obsolescent. The wet-season form of B. boydi is still unknown. 

 To judge by the analogy of B. gotzius, its upper surface must be 

 still more heavily marked with black than that of the specimens 

 collected by Prof. Balfour and Mr. Bennett. 



PxEAMEis CABDUi Linn. (Nos. 8, 9.) 



2 5 . This species was also observed by Prof. Balfour. 



" Common everywhere. The three most abundant species, in 

 order of frequency, were (1) Calysisme any nana, (2) Byhlia hoycli, 

 (3) Pyrameis carclui." — E. N. B. 



JuNONiA CLELiA Cram. (Nos. 23-28.) 



Six specimens ; 2 cS , ^ $ : two of the latter in a battered 

 condition. These do not differ in any definite manner from 

 specimens from the mainland and the Comoro Islands \ They are 

 " dry-season " forms, the colouring of the hind-wing underside 

 being fairly uniform and the ocelli obsolescent. This species was 

 not obtained by Prof. Balfour. 



" Very common in the mountains." — E. N. B. 



Hypolimnas misippus Linn. (Nos. 29-32.) 



4 5 . These are of the ordinary form, showing no tendency 

 towards var. alcippoicles Butl. They have suffered much from the 

 attacks of larvae. Not obtained by Prof. Balfour. 



" Fairly common ; commoner than L. chrysippus. Chiefly in 

 the hills. Flight strong."—^. N. B. 



' In tZ epiclelia Boisd., from Madagascar, the size of the creamy-white 

 markings of the upperside is much reduced, but I doubt whether the other 

 features mentioned by Trimen {loc. cit. p. 216) are constant points of difference 

 from J. olelia.
