upwards, forming very little more of a club than in Mahathala, slightly stouter than in 

 that genus. 



Genitalia, approach closely to the pattern of the genus Arhopala with the fully 

 developed tegumen and the small clasps ; the tegumeu is composed of a full hood, the 

 hooks having a strong muscular attachment, straightish as in Mahathala ameria, but 

 with a decided deflection. The clasps are small, with the extremities projected well 

 outwards, which can be seen better in the figure than it can be described. The penis 

 is unusually short and moderately robust.

Imago. — Male. Upperside black, with the basal area smalt-blue or silvery- 

 blue, otherwise the colour of the wings is blue with very broad black borders 

 covering all but the basal, discoidal and sub-median areas. Cilia and tails also black. 

 Underside, dark vinous-brown. Forewing with the outer half and lower portions 

 paler, three blue spots in the basal half of the cell, a larger one at the end with a 

 brown dot inside it, a discal band of six separate square spots, from the costa to vein 2, 

 the first two outwardly oblique, the third outside them, the next three, a little on the 

 inner side of each other, a sub-marginal series of acutely angled marks. Hindwirig 

 generally darker than the forewing, with three outwardly curved irregular bands of 

 separated spots with pale edges, ante-medial, medial and discal, often very indistinct ; 

 anal area with some bronzy or bluish scales, and a few similar scales near the base and 

 sometimes on other portions of the wing. 



Female, like the male above and beneath, but on the upperside the blue area 

 is generally paler and less silvery, on the underside the wing is not quite so dark, 

 especially the lower portion of the forewing, the markings are more distinct, and the 

 blue scalings on the hindwing more numerous. Antennae black ; palpi black above, the 

 two basal joints grey beneath ; head and body black above, brown beneath. 



Expanse of wings, $ % I^q to 1^-^ inches. 



Habitat. — Burma, South India. 



Distribution.— The type came from Taoo, in Tenasserim ; de Niceville records it 

 from the Meplay Valley, Upper Thoungyin and the Nilgiris ; we have it from Kolar, 

 Karwar, and Tenasserim.
