Wet-season brood

The upperside of the male has the groundcolour white. Fore wing has the base densely and broadly irrorated with black scales which gradually merge along the costa into the black apical area that occupies about one-third of the wing, the inner margin of this area irregular, passing in a curve from costa to vein 4, thence vertically to vein 3 outwards in interspace 2 and irregularlv to the dorsum ; a curved preapical series of four or five white spots superposed on the black area. Hind wing: slightly irrorated with black scales at base which leave a terminal series of large, somewhat diamond-shaped, black spots at the apices of veins 3 to 7. Underside, fore wing : white, apex butter-yellow, a somewhat narrow zigzag curved irregular black band from middle of costa to tornus. Hind wing : uniform butter-yellow.

Female has the upperside similar to that of the male, but differs in the much greater extent of the black area which occupies the outer apical half of the fore wing and on the hind wing forms a broad continuous terminal band; the superposed spots on black area of fore wing reduced to two and the irroration of black scales at the bases of the wings more dense ; on the hind wing this latter extends subdorsally to the black terminal margin. Underside, fore wing : white, basal half of cell suffused with sulphur-yellow; a very broad curved black band crosses the wing from costa to tornus, the inner margin of this irregular, the outer margin fairly even ; apex pearly bluish-white. The hind wing is uniform, pearly bluish-white.

Dry-season brood

The male has the upperside similar to the wet-season form but on the fore wing the irroration of black scales at base and the black on apical area much restricted, the latter in most specimens has a more or less rubbed appearance ; the white preapical spots very ill-defined. Hind wing : entirely white, in some specimens with a faint yellowish tinge. Underside, fore wing : white, with a bluish tint broadly along the basal two-thirds of the costal margin ; apex butter-yellow ; in a few specimens the usual black curved band that crosses the wing is indicated by a few detached black
scales but in most it is entirely absent. The hind wing is uniform butter-yellow.

Female has the upperside similar to that of the wet-season form but the black area on both fore and hind wings much restricted just as it is in the male. The underside is also similar to that of the wet-season form but on the fore wing the curved black band is very much narrower, and the nacreous surface of the hind wing has more or less of a yellowish tinge. In both sexes and in both seasonal forms the antennae are black minutely speckled with white, the tufted hair on the head and thorax anteriorly greyish green, abdomen white ; beneath : head and thorax pale yellowish white, abdomen white.

The wing expanse is 65-76 mm.

This species is found in the Western Ghats and the hills of southern India.
