Male. Upperside : similar to O. amphrysus, from Java, but differs 

 in the following respects : — The anterior wing is more elongated, with 

 the yellow markings at the end of the cell much smaller ; the pos- 

 terior wing rather paler in colour, with the black scollops and the 

 black border much narrower. It is at once distinguished from all 

 other species by its bright yellow collar. The neuration of the 

 posterior wing differs slightly from O. amphrysus. 



Female. Anterior wing sooty black, with all the veins broadly 

 bordered with dusky white ; the marginal series of black spots on 

 the posterior wing are much broader than in amphrysus, almost 

 reaching the discoidal cell ; very like the posterior wing of O. 

 miranda, Butl. 



I have examined 35 males and 7 females of this species, and they 

 do not differ in any respect.
