BUTTERFLIES FROM THE 1ND0-MALAYAN REGION. 369 



lines from the outer margin of both wings on the underside being 

 more strongly zigzaged, and especially by the entire absence (as in 

 L. anops, Doherty) of an orange subaual spot on the hindwiug in the 

 submediau interspace, which is so large and conspicuous in L. subdita. 

 L. philatus is a very distinct species. 



Described from a single example, which I owe to the generosity 

 of my friend, Mr. W. Doherty. 



18. ACESINA ARISBA, n. sp., PL F, Fig. 19, 6 . 



Habitat: Burma (Tilin Yaw and Maulmain). 



Expanse : 6 , 1*3 to 1'5 ; ? , 1*2 inches. 



Description : Male. Upperside, both wings shining bluish- purple. 

 Forewing with the costa narrowly, the outer margin somewhat broad- 

 ly black, broadest at the apex ; cilia anteriorly black, becoming white 

 towards the anal angle. Hindwiug with the costa broadly, the outer 

 margin less broadly and decreasingly towards the anal angle black, 

 bearing from the anal angle to the second median nervule a very fine 

 marginal bluish-purple line. Tail narrow, black, tipped with white. 

 Underside, forewing with the ground-colour of the basal half brown, 

 of the outer half grey ; the markings similar to those in A. paraganesa, 

 de Niceville, but differing from A. aberrans, de Niceville, in that the 

 discal band is continuous instead of strongly broken in the middle. 

 Hindwing similarly coloured and marked as in the same wing of 

 A. aberrans. Female. Upperside, forewing as in A. aberrans, but 

 having a single whitish spot beyond the disco-cellular black spot 

 only, and lacking the two black spots divided by the second median 

 nervule more or less present in that species. Hindwing as in 

 A. aberrans. Underside, both icings as in the male. 



The male may at once be known from A. aberrans by the outer 

 black border to both wings on the upperside being over a millimeter 

 in breadth, instead of being reduced to a fine line only ; the female is 

 distinguished by having one whitish spot only on the forewing ; both 

 sexes may be known by the unbroken discal band of the forewing on 

 the underside. 



Described from four males and a female in my collection taken by 

 Lieutenant E. Y» Watson at Tilin Yaw, Burma, in March and April, 

 1890. He has also kindly sent me four males and two females of
