Description

The male is brown with slight traces of olive. The forewing has two transverse short black lines at the base, a black loop across the middle, and another beyond apex of cell, with their centres dark brown, followed by an angulated discal dark brown band bordered outwardly by a series of five white spots; two preapical white spots beyond and a broad, somewhat diffuse, subterminal black band broadening over the apex and angulated inwards in interspace 1. Hind wing shaded with dark brown at base, two crescent-shaped dark brown loop-like marks in cell; a discal series of dark brown, elongate, outwardly acute, inwardly diffuse, somewhat hastate spots, followed by a subterminal series of small spots of the same colour. Underside ochraceous brown. Fore wing on the underside shows five transverse slender black lines across cell; a black spot below median vein; discal and preapical white spots as on the upperside, succeeded by a postdiscal series of somewhat diffuse crescent-shaped black marks, and a broad terminal pale lilac band not reaching the apex, bordered narrowly along the termen with dark brown. Hind wing with four or five slender black loops at base, a posteriorly obsolescent postdiscal series of diffuse black marks and a subterminal series of black dots; the termen near apex touched with pale lilac. Antennae, head, thorax and abdomen dark brown, the antennae ochraceous at the tip, the body paler beneath.
The female is similar but of a paler shade. Upperside forewing differs from that of the male in the absence of the dark discal and subterminal bands, and in the series of discal spots being elongate, much larger. The hind wing has the discal series of outwardly pointed black-markings only as traces. Underside similar to that of the male, but the groundcolour more ochraceous, the markings larger, more diffuse.[2]
Race vasanta, Moore is found in Sri Lanka. It resembles the nominate race, but in the male the white spots on the fore wing are entirely absent, above and below ; the discal hand on both fore and hind wing on the upperside is more irregular and not nearly so well-defined ; on the fore wing the interspace between it and the subterminal band and on the hind wing the posterior half suffused with dark green 5 the terminal margin of the fore and anterior half of the hind wing tinged with pink. Underside similar, but both the ground-colour and markings paler; the latter less prominent. Female. Differs prominently on both upper and under sides in the discal row of white spots being more oblique and complete, extending from the costa to near the apex of interspace 2. [2]
Race acontius is found in the Andaman Islands.
The wing expanse is 68-79 mm.
