ltong__'s Identifications

Male:
Upperside: black. Forewing with more or less distinct, somewhat diffuse, broad streaks from base, in the discoidal cell and interspaces 1 and 2, the streak in the last the most produced; a white oval spot at lower apex of cell traversed by the lower discocellular, followed by a subterminal series of greyish-white hastate (spear-shaped) markings with their points turned inwards, the markings opposite the apex of the wing elongate and shifted a little inwards. Hindwing: a broad subbasal transverse greyish-white band merged posteriorly in a large bright yellow dorsal patch that fills the apical two-thirds, the extreme apex excepted, of interspaces 1a, 1, and of 2; a white transversely elongate spot along the middle discocellular, and beyond it a postdiscal curved series of greyish-white elongate hastate spots in interspaces 3 to 7.

Underside: black. Forewing: somewhat elongate greyish-white markings in interspaces 1, 2, 3 and in cell, formed into a conspicuous oblique broad bar across the middle of the wing; a white spot at lower apex of cell and a postdiscal series of hastate spots as on the upperside. Hindwing: black, a rich dark crimson patch at base, a yellow dorsal patch as on the upperside but darker; the apical two-thirds of the cell, three spots above it and one below at bases of interspaces 3, 6 and 7 respectively and a curved discal series of elongate spots beyond apex of cell, rich chrome-yellow; of these latter spots the spot in interspace 5 is much the longest. Antennae, head, thorax and abdomen above black, abdomen on the sides and below grey.

Female
Upperside: brownish black. Forewing: markings as in the male, but the cellular streak and the streaks in interspaces 1 and 2 below the cell short and formed into a broken oblique broad greyish-white band across the wing. Hindwing: markings similar to those in the male, but the basal crimson patch of the underside seen through by transparency, the transverse broad subbasal band and dorsal patch both pale yellow and much broader than in the male, and the postdiscal curved series of hastate spots obscure and ill-defined. Antennae, head, thorax and abdomen as in the male, the abdomen whitish grey below and on the sides.

Wingspan is 66–90 mm.
