$ Lihe $, hut rather paler, and ivith all the vitreous spots of fore- 

 wing larger. Fore-iving : disco-cellular enlarged vitreous spots touch- 

 ing or almost touching, and not rarely confluent. In both sexes the 

 size of the disco-cellular and discal vitreous spots of the fore-wing 

 varies considerably, and in some $ s they are even minute. 



]]oisduval {op. cit.) described as Ophioii Madagascar specimens 

 which, except for their smaller size, he could not distinguish from 

 Drury's West-African type-form ; but M. Mabille {loc. cit.) has sepa- 

 rated the Malagasy insect as 1\ insularis. Trom the latter author's 

 full description of the two examples lie possessed, I am disposed to 

 conclude that Boisduval was right in regarding the insular and conti- 

 nental specimens as belonging to the same species, especially as the 

 butterfly offers considerable variation in Africa itself ; ^ but not having 

 seen any examples from ]\Iadagascar, I cannot determine the point 

 with certainty. 



Fksus has several near allies in the Indo-Malayan Sub-Eegion, of 

 which the nearest are the Indian and Malaccan P. Gana (Moore), and 

 the Javan Japctus (Cram.) ; in both these species, however, there is a 

 conspicuous broad white black-spotted lower hind-marginal border on 

 the upper side of the hind-wings. 



I first made the acquaintance of this Avidely-distributed Ethiopian species 

 in life at D'Urbaii, Natal, in June 1865, and again took it there in the follow- 

 ing August ; and in February and March 1867 captured a good many speci- 

 mens there and at two other localities on the JSTatal coast. It is active and 

 rapid in flight ; the white under side of the wings renders it then conspicuous, 

 but it has the habit of settling constantly and very abruptly on the under side 

 of leaves, so as suddenly to disappear from view altogether. When thus 

 settled, the wings are held fully expanded. I only on one occasion took an 

 example on a flower.

1 StoU's figure (oj). cit.) of a "Sierra Leone" specimen represents the discal series of 

 black spots and the hind-marginal brown border on the under side of the hind-wings as 

 much more developed than in any South-African examples which I have seen.
