less broadly whitish round tbe apex calathus, Hew. 



5 (4). Sex-mark on fore wing above in the male linear, blackish, erect from

6 (3). No cell-spot on fore wing above. 



7 (8). Hind wing above in the male with a tuft of long hairs near the base 



completely covering the cell ; the latter very short, about one-third 

 as long as the wing, transverse vein suberect, veins 3, 4, and 6 

 equidistant at the base and much thickened in their basal half. Hind 

 wing below brown, yellowish next the transverse vein zenoti, de Nicev. 



8 (7). Hind wing above in the male normal; below brown, with a sharply 



denned yellow transverse band from the apical third of the costa to 

 the basal third of the dorsum but interrupted in cell 1 b. No cell-spot 

 on tbe fore wing above avesta, Hew. 



9 (2). Hind wing below brown, with a white median band from the costa to 



vein 1 b, the breadth of this band equal to half the length of the wing, mytheca, Hew. 



10 (1). Hind wing above in part yellow. 



11 (12). Fore wing above with a cell-spot, no pale spots in cells 6, 7, or 8. Hind

12 (11). Fore wing above with a cell-spot and a pale spot in each of cells 6 and 7
