" </ Closely allied to A. xanites, Butler, from the Malay Peninsula, 

 Java, and Borneo. Upperside, both wings dark fuliginous-brown, strongly 

 suffused with purple, and glossed with dark bronzy-brown according to the 

 play of light. Forewing entirely lacking the broad orange band so 

 conspicuous in A. xanites. Underside, forewing paler and less strongly 

 suffused with purple, paling from the middle of the interno-median area to 

 the posterior margin. Hindwing plum-coloured, with the anterior margin 

 fringed at the base with black bristles forming a tuft, which is lodged in, and 

 nipped by the lips of, an elongated sac-like fold in the cell of the fore- 

 wing. 9 . Larger than the male. Upperside, forewing with an obsolete 

 oblique discal red band, which is sometimes quite absent, but distinct traces 

 of which are always to be seen on the underside, which is rather lighter 

 everywhere and less stongly suffused with purple than in the male. The 

 hindwing, of course, lacks the tuft of black bristles present in the opposite sex. 



Expanse: tf I '5'j 9 1-7 inches. 



Three males and four females in forests near Silcuri [Cachar] , 8th to 

 igth July. 



It is by no means an uncommon species at low elevations in Sikkim 

 and Bhutan, and it has also been obtained in the Mergui Archipelago." 

 (Wood-Mason and de Niceville, 1. c., in J.A.S. B. of 1886). 



Also recorded from Sikkim (de Niceville, Elwes}. 



Near to A. olivascens but can be distinguished by the absence of mark- 

 ings on the underside of the hindwing.
