Male upperside dull white. Fore wing: base and costal margin irrorated with black scales; cell with the usual medial and apical short black transverse bars, the former not extended down to the median vein in typical specimens; discal and postdiscal dusky black sinuate bands, the former attenuated below vein 6, stops short of the dorsum, the latter extends right down to the dorsal margin; beyond these bands the terminal margin is more or less shaded with dusky black which at the tornus coalesces with the postdiscal band. Hind wing: dorsal margin broadly dusky black, this colour narrowed towards the tornus; a postdiscal black-encircled red spot in interspace 5; termen somewhat broadly dusky black, with a subterminal series of darker spots in the interspaces and the dorsal margin fringed with long white hairs. Cilia of both fore and hind wings white. Underside: like the upperside, the ground-colour with the glassy appearance common to all forms in the genus; markings similar, apparent however more by transparency from above than formed by actual scaling. Antennae, head, thorax and abdomen black, the tufted hairs on the head in front fuscous; beneath: the palpi, thorax and abdomen clothed with fuscous hairs. Female upperside the groundcolour differs from that of the 6 in its duller somewhat yellowish tint; the markings are similar but on the hind wing the spots in the sub terminal series are centred with blue, the postdiscal red spot is paler, often absent, while in some specimens there is a subtornal red spot. Underside: similar to that of the male. In both sexes the basal red spots on the underside of the hind wing so general in the forms of this genus are usually, if not always, lacking. Antennae, head, thorax and abdomen as in the male. Anal pouch in the fertilized female as in Parnassius hunza
