In Mus. Hopeiano Oxonice, Dublinensi, §Tc. 



Specimens of this lovely insect were taken in Guinea by the late 

 celebrated entomologist, Herr Westermann, of Copenhagen, by whom 

 the species was communicated to the Rev. F. W. Hope, M. Boisduval, 

 and other entomologists, and the specific name adopted above was 

 proposed for it by the last named author ; but no description has 

 hitherto appeared of it. These were the only specimens hitherto 

 known of the insect in British or Continental collections. I have, 

 however, just received an interesting communication from Mr. W. F. 

 Kirby, the indefatigable Keeper of the Eoyal Dublin Society's Natural 

 History Museum, from which it appears not only that specimens of 

 the male supposed to have been collected at Cape Coast are contained 

 in that collection, but that he has also discovered in it a specimen 

 which he considers to be the female. It is without a label, but pinned 

 in the same way as the others, " from which it differs strikingly on 

 the upper side. It is brown above, the base darker, the whole of the 

 centre of the hind-wings filled with a broad orange band (much duller 

 than in the male), which extends to the adjacent portion of the fore- 

 wings, curving inwards across the cell, where it becomes much more 

 obscure. The orange band of the hind-wings seems to have been edged 

 with lilac-blue, and there are traces of detached bright blue scales in 

 the cell of the fore-wings. There is a row of five black spots towards 

 the edge of the orange on the hind-wings (visible on the under-side 

 in the male also), and continued, in the female, on the fore-wings, 

 although the only conspicuous spot is one near the hinder angle of the 

 fore-wings. Beneath, the female chiefly differs in wanting nearly all 

 the dark markings, and in the orange markings being more suffused, 

 and not sharply defined as in the male."
