Hab. Malacca; Sumatra; Borneo; Silam. 



Expanse, d 46-50, 2 48 mm. 



? . Upperside : both wings pale violet ; primaries with a broad brown costa up to 

 the cell, a very broad and slightly increasing (as it nears the apex) outer margin, and 

 yet broader apex ; secondaries with very broad costa and broadish outer margin, 

 increasing very considerably at the anal angle ; underside exactly like that of the male. 



Until now the female of this species does not appear to have been recorded ; but 

 Mr. Cator was fortunate enough to capture one at Silam, an island off the coast of 

 British N. Borneo, on the 26th of January, 1892, which is the type female and is in 

 his collection. 



This species, though by no means the largest in size, is, I think, about the most 

 magnificent of the genus, the intense richness of the deep ultramarine-blue of the 

 upperside and the most beautiful softness of the tones of the under surface, coupled 

 with the rich depth of the basal area, combine to make it a species so striking that 

 once seen it will never be forgotten. It appears to be a rare insect ; I have only seen 

 a single specimen from each of the localities given, each of which is from a different 

 collection.

Hab. Sikkim. 



Expanse, 6 46—50, ? 46-48 mm. 



This species is quite distinct and easily separated from apidanus Cram, by the broad 

 outer border to the primaries, and by the underside pattern, which is quite different ; 

 the broad outer border of the primaries also separates it from asoka de N. It is 

 a very local insect, only having been recorded from Sikkim ; I have specimens also from 

 Darjeeling. The genitalia are most peculiar ; the tegumen is elevated into a high 

 saddle-back ridge, and then carried forwards into two strong, curved, pointed tusks, 

 jointed at the base with the tegumen, below which are the usual hooks. The clasps 

 are composed of two portions, the hinder portion extending upwards with a hammer- 

 shaped head, the fore portion small, subtriangular, joined at its lower hind extremity 

 to the other part. The penis is stout, strongly curved in its whole length.
