Male. Upperside deep sulphur-yellow. Forewing with a large somewhat 
quadrate vinaceous-black apical patch, which continues narrowly and decreasingly 
sinuously hindward, from above lower radial veinlet to below the lower median; the 
patch slightly varies in size, and its inner anterior side is slightly outwardly-oblique 
and uneven, its upper angle extending inward very slenderly aud interruptedly along 
the costal edge to tip of the costal vein, and its entire inner edge from the costa 
hindward is bordered by a narrow pale ochreous-red band ; a similar-coloured narrow 
transverse discal fascia also extends from the inner lower angle of the black patch 
obliquely to the submedian vein ; a pale oclireous-red recurved streak also borders 
the discocellulars ; cilia anteriorly ochreous-red. Hindwing with a black dot at end of 
each vein. Underside paler yellow. Forewing with markings, as on upperside, 
purplish-red, the apical portion of outer band washed with dark purple-grey and 
crossed by a glossy violet oblique streak, the whole traversed by darker slender 
strigse ; centre of the discocellular streak glossy violet and its base dark purple, the 
transverse discal fascia pale and inwardly edged with dark purple-grey. Hindwing 
with a black dot at end of the veins, a slightly-defined transverse discal purple-red 
fascia extending straight from the costal vein to middle median and then bent inward 
to lower median, its inner edge being more distinct; a discocellular similar coloured 
trilobed mark with glossy violet centre. 
Female. Upperside pale olivescent yellowish-white. Forewing with the apical 
patch and marginal band blacker, the patch somewhat longitudinally narrower and 
its lower inner angle prolonged inward, the ochreous inner border absent, and the 
discal fascia obsolescent. Hindwing with a black dot at end of the veins. Underside 
very pale sulphur-yellow, the markings as in male; the apical band of forewing 
paler.
