Male. Upperside sulphur-yellow. Forewing with a small black somewhat 
quadrate apical patch, reaching to the upper radial, below which it marginally 
extends narrowly and sinuously to beneath the upper median veinlet, and followed 
by a very small spot on the middle median and then a dot on the lower median ; 
anteriorly the patch is slenderly continued sinuously and interrupted along the costa 
to tip of the costal vein; a large black rounded discal spot placed somewhat 
inwardly-oblique between the upper and middle medians, this spot being more or less 
indistinctly and narrowly bordered posteriorly by ferruginous, a few similar coloured 
scales also forming a short obsolescent fascia below it. Hindwing with a minute black 
dot at end of the veins. Underside somewhat paler yellow than above. Both wings 
basally sprinkled with a few ferruginous dots, and a small bilobed, or geminate ferru¬ 
ginous discocellular mark, bipupilled with glossy-white. Foreiving with the apical 
and marginal markings more restricted, ferruginous, the apical patch centred with a 
glossy-white streak ; the discal rounded spot dark ferruginous, inwardly bordered 
with blackish scales, its centre being paler ferruginous; a narrow ill-defined 
ferruginous-scaled oblique discal sinuous fascia extends from the apical patch to the 
discal spot and then below it to near the submedian vein. Hindwing with a basal 
ferruginous spot centred with glossy-white; a transverse discal ill-defined narrow 
ferruginous sinuated fascia, which is bent inward at the middle median, each portion 
of which between the veins being marked inwardly by a dark lunate dot; a similar 
marked ferruginous spot is also present in the costal interspace above end of the 
cell, and one also basally between the lower median and submedian ; veins with a 
black dot at their tip. 
Female. Upperside much paler, somewhat whitish basally. Forewing with 
black markings, similar to the male, except that the outer band is more restricted, 
deeply sinuate below the apex, and more macular posteriorly, the discal spot is also
