Yellow rajah

Appearance

The male has the ground colour of the upperside rich ochraceous tawny. Fore wing has a black subcostal spot at the discocellulars and a pale chestnut line on either side of them; a very short slightly curved discal narrow band from vein 7 to vein 5, a postdiscal broad oblique band from costa to vein 6, and a broad terminal band from apex to vein 1, jet-black ; the extreme margin of the termen touched interruptedly with fulvous tawny; the postdiscal band continued as a curved lunular narrow chestnut band to vein 1, and the black at apex continued along the costa, joining the postdiscal band above. Hind wing: costal margin broadly pale yellow, terminal third of wing of a darker tawny shade than the base, a short discal broken black line from costa to vein 6; a subterminal slightly curved series of outwardly pointed black spots, increasing in size to interspace 6, the tornal two centred with white; the terminal margin somewhat broadly dark reddish brown. Underside bright ochraceous yellow. Fore and hind wings crossed by the usual sinuous black lines, the postdiscal line outwardly lunular. Fore wing: the discocellulars defined by dark lines, the apex with two short white streaks continued as a line of obscure white dots to interspace 1. Hind wing: the space between base of wing and subbasal dark line and between the median two dark lines darker ochraceous than the ground-colour; the postdiscal lunular line with a dark shade beyond, traversed by a series of heavy slate-black lunules, and white, black-tipped obscure dots ; the terminal reddish-brown band as on the upperside. Antennae black annulated with white; head, thorax and abdomen tawny; beneath paler, the palpi white.

The female is similar but the ground-colour on the disc paler. Fore wing: the short discal band very broad, continued as a series of lunules in the interspaces to vein 1 : the postdiscal lunular line slender above, not joined onto the black on the termen, and sometimes black, sometimes chestnut-coloured; the black on the margin formed into a subterminal series of large black inwardly conical spots, the termen beyond dusky ochraceous. Hind wing: the subterminal row of black spots with white central transverse very short lines. Underside much as in the male, but the slate-black lunules on the hind wing form a broad obliquely placed line ; the subterminal series of white spots larger and more conspicuous both on fore and hind wing; upper tail spatulate, much longer than in male.
