Male. Fore wing ochreous green, numerously covered with slender black transverse 
strigz, those across the disk and on exterior margin grey-bordered ; crossed by a curved 
antemedial and an oblique postmedial black line, both with chalybeous-grey inner 
border; reniform mark indistinct: hind wing orange-yellow, with broad black mar- 
ginal band and small white cilial spots and narrow streak at apex. Thorax, head, 
palpi, and legs in front ochreous-green, palpi with a lateral linear grey streak ; abdomen 
and legs above orange-yellow, beneath greyish. 
Female. Darker ochreous green, with a cluster of creamy-white spots on the disco- 
cellular area, another series below the cell, a large patch at the posterior angle, and a 
slender linear broken spot below the apex: hind wing and body as in male. 
Expanse 22 to 3 inches. 
Hab. India (Coromandel, Silhet); Java. 
This species has a similar pattern of markings to R. hypermnestra, but may easily be 
distinguished from it by the absence in the hind wing, in both sexes, of the two black 
discal spots, and in the black marginal band extending to the anal angle, the immer 
border of which is much less irregularly sinuous, and the row of cilial spots also are 
much smaller; the fore wing in the male has the two transverse lines more curved, 
and the clusters of spots in the female are more confluent. It has been reared in Java 
by Dr. Horsfield from larva feeding on a species of Epibatherium.

Male. Fore wing ochreous-green, numerously covered with slender blackish trans- 
verse strigee ; crossed by a distinct antemedian and an oblique postmedian brown line ; 
an indistinct dusky brown suffused reniform mark; a curved grey streak below the 
apex, and grey strigze above posterior angle; transverse lines with chalybeous-grey 
inner border. Hind wing orange-yellow, with broad marginal black band, white cilial 
row of spots and apical angle ; and two small black discal spots, the upper one oval, 
the lower recurved. Thorax, head, palpi, and fore legs in front ochreous-green, palpi
