 streak in the middle of the inner margin. Posterior wings pink, except at tlie base, 

 which is rather broadly dusky grey; an irregular row of black spots surrounds the 

 cell, of which the spot between the two upper median nervules is out of line and 

 nearer the margin, and the spot above it is nearer the cell; a rather large spot in the 

 cell, a spot above the cell, and a cluster of spots near the inner margin towards tlie 

 base, some of which merge in the dusky liasal area; outer margin narrowly dark grey. 



Underside : anterior wings pinkish dull brown, with a small spot at the end of 

 the cell, an irregular row of six spots across the disc, and another below the sub- 

 median nervnre. Posterior wings pale tawny, with a basal broad pink band extend-

 sjiot in the cell near the base. On the upperside the basal tawny area is rather more 

 extended, thus resembling .1. ceruMi Hew., and on the ]iostcrior wings it extends 

 lower towards the anal angle; both wings are dusky grey at the base. 



Exjianse of wings : 2 inches.
