3fale. Fore wing ochreous green, numerously covered with slender black transverse

 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 2f to 3 inches.

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 inner 

 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 Ejnbatherium.
