 the cell, one between veins M 3 and Cu 1; and the other close to it just below vein 

 Cux ; a black, interrupted, zig-zag subterminal fascia commencing very close to 

 apex, forming a prominent black spot between veins R 5 and M. x , and becoming 

 less pronounced towards tornus, ending in a distinct spot before the tornus and 

 above vein A 2 ; the postmedial fascia is preceded, between veins R x and Cu l5 

 by some irregular blotches of black scaling beyond the end of the cell ; a 

 terminal series of interneural black dots joined by a fine crenulate blackish 

 brown line. Fringe warm buff suffused with russet. Hindwing with a light 

 buff ground entirely suffused with fuscous, fringe warm buff. 



Underside : forewing buff brown, with some drab to greyish olive in the

 M 3 and Cu x from the cell, vein Cu 2 from well before the angle of the cell. Hind-
