Description

Male upperside: plumbeous blue. Fore and hind wings: anticiliary jet-black lines ; on the hind wing subterminal subequal black spots in interspaces 1 and 2, beyond which there is a terminal white thread that does not extend beyond those two interspaces. Underside: french-grey; principal markings chalky-white, somew hat diffuse. If ore wing: a pair of short transverse white lines across the middle and another pair at the apex of cell, one on each side of the discocellulars, these latter not extended to the apex but in most specimens indicated there by two white spots; a complete transverse catenulated discal band composed of two parallel white lines, beyond which the ground-colour looks as if it had been chalked over; the terminal markings however, though blurred consist of an inner and an outer transverse series of white fannies succeeded by an anticdliary white line. Between, the transverse pairs of white lines, medial and discal, and between the subterminal series of lunules, the ground-colour is distinctly darker, between the latter and the anticiliary line it takes the appearanoe of an incomplete transverse row of dark spots. Hind wing: the following transverse white, somewhat indistinct lines;— two basal, a single line on the inner side of the discocellulars, two irregular and discal, followed by double series of white lunules; a white anticiliary line and subterminal row of dark spots as on the fore wing; subterminal black spots, broadly margined on the inner side with ochraceous orange in interspaoes 1 and 2; tail black tipped with white. Antenna, head, thorax and abdomen dusky brown, the shafts of the antenna speckled with white; thorax and abdomen suffused with blue; beneath: palpi, thorax and abdomen white.

Female upperside: fuscous black. Fore wing: posterior two-thirds pinkish brown shot with iridescent blue; a jet-black anticiliary line; cilia dark brown. Hind wing: basal three-fourths shot with a duller paler blue than on the fore wing; very obscure postdiscal series of slender pale lunules, followed by the dark ground-colour and beyond it by a subterminal series of slender lunules, those in the interspaces 1 and 2 ochraceous orange, the others white; a series of jet-black spots, a slender terminal white line and a conspicuous jet-black anticiliary line; cilia white alternated with dark brown at the apices of the veins. Underside: similar to that of the male, but the ground-colour paler, the markings, especially the terminal markings, more clearly defined. Antennae, head, thorax and abdomen as in the male.
