* It has black upper forewings with a thin prominent yellow discal band running across the wing, parallel to the body.
* The upper hindwing has a large blue discal patch which tapers off into a greenish yellow band from its lower edges inwards towards the dorsum. It has a series of red-mauve capped crescents (usually five).
* The upper hindwing discal band appears on the under hindwing also as a prominent curved yellow discal band.

Resembles ''Papilio paris'' generally, but differs in many points as follows: Upperside: ground colour more of a brownish black, irrorated similarly to parti with, green scales, but the scales smaller and more sparsely spread. Forewing: the postdiscal transverse band well defined, complete, formed of white scaling with only a thin sprinkling of green scales on its inner margin, generally erect or slightly curved, rarely slightly sinuous. Hindwing: upper discal patch metallic greenish blue, smaller than in ''P. paris'', but the portions of it in interspaces 6 and 7 more extended towards the termen, the metallic golden-green band that joins the patch on its inner side to the dorsal margin more conspicuous than in ''P. paris''; the tornal ocellus as in ''P. paris'', but above it a subterminal series of claret-red lunules in interspaces 2, 3, 4 and 5, followed by a series of ochraceous-red obscure terminal narrow lunules in the interspaces, the cilia on the outer margin of each conspicuously white. Underside: forewing as in ''P. paris'' but an erect ochraceous-white postdiscal band as on the upperside limits; the series of internervular pale streaks on the outer half of the wing. Hindwing: a well-defined discal ochraceous-white band formed of a series of somewhat lunular marks in the interspaces, these increase in width anteriorly; a subterminal series of claret-red lunules traversed by violet scaling on the inner side as in ''P. paris'', but much broader and more prominent; finally a terminal series of ochraceous-yellow lunular marks in the interspaces; the cilia that border each lunule white. Antennae, head, thorax and abdomen as in ''P. paris''.
