a broad rounded loop odged with deep l)la('k and clouded 

 with blackish ; it lies in a nearly rectangular blackish blotch 

 whicli occupies the dorsal portion of the space between the 

 first and second lines ; the spaces between the white nervures 

 and around the other two stigmata are also black, except the 

 subcostal region which remains whitish with small grey 

 costal clouds ; before the apex is a blackish costal triangle 

 containing one or more black streaks ; hind mai'gin partially
