 hyaline, outwardly oblique band commencing with a small ochreous spot close to the 

 costa a little beyond its middle, attached to a moderately large, sub-quadrate 

 .spot with its outer side indented, a well separated sub-quadrate spot of similar size 

 in the first median interspace, a small round spot attached to its upper outer 

 side, and another (sometimes two) Ijelow, close to its outer lower end. Illndwlny

 yellow spots, often entirely absent. Cilia of both wings blackish. Underside as

Habitat. — Ceylon. 



Appears to be a common species in Ceylon and confined to that island. Our 

 description and figures are from Ceylon specimens in our collection. Our figures of 

 the larva and pupa are from Green's original drawings. Hampson and Evans record 

 it from India, but we have not seen any typical spilothyms, except those from 

 Ceylon.
