Charles Thomas Bingham (1907) gives a detailed description:
Race fieldi, Ménétriés
♂.Upperside deep cadmium orange-yellow.Fore wing : a patch of greenish-black scales at extreme base, a pear-shaped black spot on the discocellulars and a broad terminal black border ; the last occupies about a fourth of the wing and has its inner margin curved slightly and irregularly crenulate, broader at apex and the tornus than in the middle ; the end portions of veins 6, 7, 9 and 10 subterminally pale and conspicuous on the black of the apex. Hind wing : a thin covering of long soft hairs at base,beneath which is a dusting of black scales that is continued outwards along the posterior half of the wing ; dorsum broadly pale yellow; terminal border broadly black, broadest in the middle,its inner margin crenulate ; discocellular spot large, consisting of a small patch on which the ground-colour is paler and brighter and that encloses two somewhat obscure dusky rings, the upper one minute. Cilia of both fore and hind wings broadly salmon-pink. Underside : light orange-yellow, the costal margin narrowly,terminal fourth of the fore wing and the whole surface of the hind wing overlaid with pale dull green ; the costa, termen and dorsum, with the cilia of both fore and hind wings, salmon-pink.Fore wing : discocellular spot as on the upperside but centred with silvery white ; a postdiscal transverse Aeries of black spots,obsolescent and curved inwards anteriorly, conspicuous and increasing in size posteriorly. Hind wing : a discocellular double spot conspicuous silvery and circled by a diffuse salmon-pink ring, followed by a very obscure, almost obsolete, transverse, post-discal series of pinkish spots. Antennae, head and thorax anteriorly salmon-pink, club of antennae darkening to brown ;thorax and abdomen dusky greenish black ; beneath : palpi, thorax and abdomen yellow. Sex-mark, a patch of thickly set light yellow scales at base of interspace 7 on the upperside of the hind wing. ♀ .

Underside : precisely similar to that of the ♂ .Antennae, head, thorax and abdomen on the upperside iis in the ♂ ; beneath : the palpi and thorax more or less salmon-pink.
