between three of the pairs of lines being filled in with dark brown, 

 so as to form one subbasal and two antemedial bands ; a dark- 

 ringed pale speck at end of cell, the pale centre being sometimes 

 obsolete ; four post medial curved lines ; an oblique dark band from 

 beyond the middle of the costa to outer angle, in some of the 

 forms produced outwards along vein 5 so as to be more oblique ; 

 a pale submargiual obsolescent line from below the apex to outer 

 angle, sometimes carried out to the margin at vein 4. Hind wing 

 brownish fuscous, with traces of a pale patch and dark lines near 

 anal angle. Underside more or less suffused with ferruginous, 

 ochreous, and grey ; the outer margin of both wings dark ; hind 

 wing with five indistinct lines. 



The form ancea is brownish grey, a small dark specimen from 

 Bhutan being nearest Cramer's figure ; in sericea the grey parts are 

 suffused with purple or pinkish ; in pseudonaga the ground-colour 

 is darker and more suffused ; whilst the colour of cinerea is more 

 uniform greyish fuscous ; the dark and light forms appear to occur 

 irrespective of locality. 



Larva green ; a series of brown dorsal spots and of lateral 

 oblique stripes on fifth to tenth somites ; an ocellated spot on 

 fourth somite ; a black stripe from first to fourth somite, with a 

 yellow line above it ; horn brown.
