The female is rather larger than the male and broader in the wing ; the 
basal two thirds of primaries limited by an obscure pale transverse band ; 
there are usually three ocelli below apex and a pale dash on costa. 
Appears to be generally distributed throughout Western China ; it also 
occurs at Chaug-yang and Ichang in Central China : Pryer has taken it at 
Yamato in Japan, and I met with it in Yesso. Fixsen records the species from 
Corea (Rom. sur Lep. iii. p. 313).
