Wet-season Brood (Figs. 1 $, la, ?, lb, $). 



Imago. — Male. Upperside with broad costal and outer marginal bands on both 

 wings. Forewing with a black spot at the end of the cell, touching the costal band ; 

 the inner area suffused with blackish with blue iridescence, except for two white 

 streaks which fill up the two interspaces above vein 2, with a small white streak in the 

 interspace above them ; the lower streak sometimes is more or less suffused with blue 

 on its outer part. Hindwing similarly coloured, with a white patch on its upper disc 

 which varies in size. Underside greyish-white, with a slight bluish tint, markings 

 brown, prominent ; a lunule at end of cell, a row of post-discal spots close to the sub- 

 terminal line, the second and third the largest, the third, fourth and fifth often joined 

 together, the sixth inwards and near the costa. Hindwing with the usual three 

 sub-basal black spots in a line, a fourth black spot near the abdominal margin nearer 

 the base ; a discal whorl of spots of the usual pattern, the first, third and sub-costal 

 spots the largest ; both wings with a sub-terminal angulated line ; a black marginal 

 line and a series of black spots between them. Cilia white, with minute brown marks. 

 Antennae black, ringed with white ; head and body black above, white beneath. 



Female, like the male, the blue iridescence less. 



Expanse of wings, $ ? 1^ to 1 j^-^ inches. 



Dry-season Brood (Figs. Ic, $, Id, ?, le, $). 



Male. Upperside. Forewing like the Wet-season form, but the white area is 

 much more extensive and the general coloration is paler, the blue iridescence more 

 brilliant. Hindwing paler, the discal white patch larger, the marginal band replaced 

 by a sub-terminal blackish lunular line, a black marginal line, enclosing a series of small 

 blackish spots. Underside with the markings disposed as in the other form, but much 

 smaller and faintly indicated. 



Female, like the male above and below, but paler above, the white patch on the 

 forewing occupying two-thirds of the inner space, the base and lower portions only 

 being suffused with pale brownish and blue iridescence ; on the hindwing above there 

 is a black spot at the end of the cell ; otherwise it is similar to the male. 



Expanse of wings, $ ? l-f-^ to ly% inches. 



Habitat. — Himalayas, Upper Burma, Assam. 



Distribution. — Eecorded by de Niceville from Chin Lushai, Naini Tal, Kumaun, and 

 Fort Stedman ; by Elwes from the Karen Hills ; in our collection from the Khasia Hills 

 and from Sikkim ; it is in the B. M. also from Nepal, Tilin Yaw and Thoungyon Valley.
