spots, the first three in a line, the fourth a little inwards on the abdominal margin, 

 followed by two unevenly formed spots, below the middle of the costa and in the middle 

 of the cell ; a discal, very irregular band of conjoined spots, three from the costa crossing 

 the end of the cell, closely followed by six or seven similar spots, from vein 6 curving 

 round to the abdominal margin, the upper one touching the second spot, the fourth 

 one touching the lower middle of the discoidal spot ; terminal line pale, a sub-terminal 

 very indistinct series of lunular marks, a black spot in the anal lobe, slightly capped 

 with metallic blue scales, the anal area smeared with pale sordid whitish, all the 

 markings much more obscure than are those of the forewing. 



Female. Upperside. Forewing dull bluish-violet colour, with very broad costal 

 and outer marginal blackish borders. Hindioing nearly all blackish, with some traces 

 of the violet colour in and below the cell, its extent varying somewhat in different 

 examples. Underside as in the male. Antennae black ; palpi brown above, white 

 beneath ; eyes ringed with white ; head and body above concolorous with the wings, 

 greyish beneath. 



Expanse of wings, $ ? I/q- to 2 inches. 



Habitat. — Sylhet, Sikkim, Assam, Burma, Sumatra, Borneo, Japan. 



DiSTRiBCTTiON. — Eecorded by Elwes from the Naga Hills, by Watson from the 

 Chin Hills, the type came from Sylhet, the type of teesta from the Teesta Valley, 

 Sikkim ; it is also recorded by de Niceville from Tenasserim ; we have received many 

 examples from the Khasia Hills, and it is in the B. M. also from the Shan States, 

 Kiushing, Gensan, Satsuma and Nikko, in Japan.

Imago. — Male. Upperside of a very dark purple colour, somewhat shining in 

 certain lights, more purple than in hazalus and of a different shade of colour ; the costal 

 and outer marginal black bands broader, especially on the forewing, the black colour, 

 however, overshadowed by the purple, and difficult to see except in certain lights. 

 Cilia, tail and projections at the end of the veins of the hindwiug as in hazalus. 

 Underside usually paler than in that species, the bands and spots similarly disposed, 

 but all usually much larger and more prominent, and the discal band of the forewing 

 ends abruptly at vein 2, and has no indications of any hindward continuation. 



Female. Upperside closely resembles the female of hazalus, the violet colour is.
