188 LEPIDOPTERA INDICA. 



Female. Upperside. Forewing with the basal portion irrorated with dark greyish- 

 brown scales, the white patch very large, occupying more than two-thirds of 

 the wing, its outer margin very irregular, the patch sometimes intersected by the 

 veins ; basal half of costal band broadly greyish-brown, the remainder black, 

 extending round the apex and outer margin, and running in on the hinder margin, 

 where in the middle it joins the grey irrorations, this outer band at the apex is very broad 

 and is black throughout. Hindwing greyish-brown, sometimes very pale, costal margin 

 very broadly blackish, a white patch in the middle of the wing which is sometimes 

 more or less suffused with grey and varies much in size. Underside, much as in the 

 male. Forewing with the white patch as large as it is above. Hindwing with the 

 discal sinuous brown line more pronounced, a short brown shade through it from the 

 abdominal margin, and both wings with lunular sub-terminal brown marks. Antennae, 

 head, thorax and abdomen brown, paler beneath, palpi and thorax beneath white. 



Expanse of wings, $ $ 1^ inches. 



Habitat. — Burma, Malacca, Java, and many of the adjacent islands. 



Distribution. — Recorded by Elwes from the Naga and Karen Hills, by Butler

Imago. — Male. Forewing, upperside, dark brownish -black at the base, a white 

 transverse band, which commences with a sub-costal streak near the base, and descends 

 outwardly before the middle of the wing, is crossed by a broad bar from the basal 

 brown space which becomes nearly pure black ; then the white band expands inwards 

 on to the hinder margin very broadly, its inner and outward edges being very 

 irregularly sinuous ; all the broad black marginal band being pure black, being very 

 broad at the apex and gradually narrowing to the hinder angle. Hindwing of a 

 uniform very dark brownish-black colour, without markings. Underside. Forewing 

 chocolate-brown, the white band much reduced, macular, and almost continuous, with 

 blackish suffusion inside it, on the centre of the wing and some similar suffusion 

 outside the band, al)ove its middle ; the outer portion of the wing with pale streaks. 

 Hindwing of a uniform rather pale chocolate-brown, some obscure mottlings of a darker 

 brown, and a brown, obscure band from the abdominal margin beyond the middle, 

 which becomes more or less obsolete inwards. 



Female, like the male. The white band slishtly narrower hindwards.
