BUTTERFLIES FROM THE INDO-MALAYAN REGION. 371 



black borders being hence much broader. It is a little peculiar too 

 in having the blue coloration of the hindwing of equal extent in 

 both sexes, in A. amanies it is more restricted in the female than 

 in the male, in the female of A. a/natri.r, however, it is of less extent 

 than in the same sex of A. amantes. In " The Butterflies of India," 

 vol. iii, p. 240, I wrote under A. amantes ;— "I possess a single 

 female specimen from Maulmain, Burma, which differs from the 

 typical form in that the anal lobe on the underside of the hindwing 

 is centred with reddish-brown instead of deep black ; the blue color- 

 ation of the fore wing on the upperside extends well above the discoi- 

 dal cell nearly reaching the costa and beyond the cell also, in the 

 hindwing it is more restricted to the base." These remarks apply 

 to the male of A. aniatrix, true A. amantes apparently not occurring 

 in Burma. 



Described from three males and two females from Tilin Yaw, 

 Upper Burma, captured by Lieutenant E. Y. Watson in April, 

 May, and June, 1890, one female from Maulmain obtained by 

 Major C. H. E. Adamson, and another female from Nubboo Chang 

 captured by Major C. T. Bingham.

 Habitat : Burma. 



Expanse : tf , 1/5 to 1-6 ; 9 , 1'7 inches. 



Description : Male. Upperside, both wings rather dark obscure 

 shining purple. Forewing with the costa narrowly, the outer margin 

 evenly and rather broadly black. Hindwing with the costa, oviter, and 

 abdominal margins more broadly black than in the forewing ; tail 

 rather long, moderately robust, black tipped with white. Underside, 

 both wings pale brown washed with shining violet. Forewing with the 

 inner margin broadly paler ; a small rounded dark pale-ringed spot 

 towards the base of the discoidal cell, an elongated spot across its 

 middle, and a third closing the cell ; two spots below the cell divided 

 by the first median nervure ; a discal slightly curved regular macu- 

 lar band ; two indistinct marginal fascia). Hindwing with the four 

 usual spots arranged across the base of the wing, a fifth below the 

 middle of, but touching the costal nervure, a sixth in the middle of 

 the cell — all these spots very small ; an elongated spot closing the cell, 

 joined posteriorly to two other spots divided by the first median
