Imago. — Male. Upperside dark purplish-brown ; costal line of forewing and 

 outer marginal line of both wings black, tail black, tipped with white. Cilia brown, 

 with white tips. Underside pale greyish-brown, lines greyish-white. Forewing with 

 a line from the median vein a little before the end of the cell, to near the hinder 

 margin a little beyond the middle, a similar line a little beyond the end of the cell, 

 nearly touching the third line which commences near the costa and runs almost straight 

 down to near the hinder margin rather close to the end of the inner sub-terminal line, 

 a line from near the costa to vein 3 ; two subterminal lines, composed of somewhat 

 lunular marks disjointed by the veins, and somewhat thicker than the other lines. 

 JLindwivg with seven disjointed transverse lines at about equal distances apart 

 covering the whole surface of the wing ; the fourth line having an additional mark 

 above its middle, making the second piece from the costa into a V shape ; the fifth line 

 runs into the sixth below the costa and is very irregular, and its lower portion is 

 composed of very short streaks and spots, the sixth and seventh lines correspond to 

 the two sub-terminal lines of the forewing, and are interrupted in interspace 2 by a 

 largish ochreous spot containing a large black spot, and there are two minute black 

 spots at the anal angle, all three spots with metallic blue-green scales. 



Female. Upperside paler than the male, in some examples almost greyish-white 

 with a blue suffusion, and with all the veins prominent and black. Forewing with 

 rather broad costal and outer marginal blackish bands inwardly suffused. Hindwing 

 with a narrower and more even blackish band, containing a series of black spots capped 

 with grey-blue, terminal line black. Underside as in the male, but all the lines much 

 broader and whiter. Antennae black, ringed with white ; head and body blackish- 

 brown above, dull whitish beneath ; the palpi white beneath, with stifi' black hairs. 



Expanse of wings, $ $ 1^% to 1^ inches. 



Habitat. — India, Burma, Ceylon, Andamans, Nicobars, and the Malayan sub- 

 region as far as Australia. 



Distribution. — de Niceville records it from Sikkim, Bhutan, Ceylon, Andamans, 

 Nicobars, Bingham from Burma, Hampson from the Nilgiris, Watson from the Chin 

 Hills ; we have received many examples from the Khasia Hills.
