Imago. —Male. Upperside black; crossed by an oblique, medial white band 
extending from just above vein 5 of the forewing to the abdominal margin of the 
hindwing. Foreioing. The band has a short production outwards, its end being nearly 
square. Hindwing. Band broader and fairly uniform in width throughout. Under¬ 
side white; all the markings black ; a very broad sub-basal band across both wings; 
a discal narrower band; in the forewing disjointed below the middle, the lower piece 
rather broader and a little on the inner side; on the hindwing this band consists of 
three rather broad linear markings, more or less joined together, the middle one nearer 
the margin than the others; both wings with a sub-terminal series of black lunules 
and a marginal black line, showing a series of white spots between them. Cilia black, 
tail long, black, tipped with white. Antennae, head and body black; the abdomen 
barred with white at the sides ; palpi, thorax and abdomen white down the middle on 
the underside. 
Female, like the male, but the white medial band on the upperside is distinctly 
broader, the inner edge of the terminal black band of the hindwing is irregular, and 
the black bands on the underside are usually also broader. 
Expanse of wings, J £ ly 1 -^ inches. 
Habitat.— Burma, Andamans, extending in the Malay sub-region as far as the 
Philippines. 
Distribution.— Manders records it from the Shan States, and Elwes from the 
Karen Hills ; it is in our collection from the Andamans, Java and Borneo.

Imago. —Male. Upperside black. Forewing with a broad, medial, white, transverse 
band, from just above vein 5 to the hinder margin ; at its commencement it is 
produced outwards above vein 8, in a nearly square form. Hindwing with an oblique 
continuation of the white band to the abdominal margin, but much broader than it is 
on the forewing, leaving only a small basal space black, and the outer black border very 
broad. Underside white. Forewing with the costal line thickly black ; a rather broad
