Imago. — ^2. Upperside brown ; in outer half of fore wing 

 clayish or ochraceous-clay tint between dark shadowy bands. 

 On fore wing underside this pale tint, often conspicuous in $, 

 almost forming two blotches between R 1 and M 1 ; termen 

 shaded with blackish-brown ; terminal area as a whole not 

 contrasting strongly with proximal two-thirds of wing, 

 particularly in 9- Distal margin of fore wing irregular,, 

 prominently lobed at R 2 ; palpus about as long as the distance 

 from its apex to base of antenna, segments 2 and 3 being about 

 twice as long as broad (inclusive of scaling). Expanse i 

 S 50-60 mm., $ 64 mm.
