Male and female. Dark brown : forewing with a marginal row of ochreous-

Second form of female (fig. l,h). Forewing with pale interspaces between the 

 veins forming a broad triangular pale area across the middle : hindwing with a more 

 or less broad medial creamy-white macular band formed of four spots which are 

 disposed side by side straightly across the disc, and in some specimens with an 

 additional small spot within end of the cell ; a crimson-red patch from the band to 

 abdominal margin ; a submarginal row of lunules and a marginal row of more 

 slender lunules, the latter with ochreous-yellow cilial border ; anal area numerously 

 covered with bluish-grey scales. 



Expanse 3^ to 4i inches. 



Third form of female — Komulus (fig. 1, c). Forewing with whitish interspaces 

 between the veins beyond the cell and across the middle : hindwing with crimson-red 

 medial spots, large submarginal lunules and narrower marginal lunules, the latter 

 slenderly bordered by whitish cilia ; discal area thickly irrorated with blue-grey scales. 



Expanse 3-| to 4 inches. 



Larva smooth, glossy-green, much attenuated posteriorly, anterior segments 

 swollen and scutellated; fourth and fifth segments with a dorsal transverse cream- 



* Cramer's name of Romulus was given to the Ceylon form of $ Pammon, and is, therefore, here 

 retained for this species.
