 beyond outer line with straight oblique outer edge; subterminal line hardly visible; termen slightly darker; 

 veins finely pale; hindwing like forewing, without inner line or cellspot. Amurland, Japan, Corea.

 costa to angle of inner line, postmedian area paler, almost whitish towards costa, clouded with brown to-

 inwardly to inner margin; hindwing with the brown dusting and suffusion heavier, with three dark brown lines; 

 of these the first bisects a large ochreous discal spot; the second is outwardly oblique from costa to cell, 

 where it curves inwards and then runs wavy to inner margin; the third is arched and double. Central and
