I have a large number of specimens from Ta-chien-lu, 

 Pu-tsu-fong, Wa-shan, Omei-shan, and Ni-tou : June and 

 July. 



In one specimen from Ta-chien-lu the ground-colour is 

 tinged with fulvous ; this is similar to a form of 8. dubiosata 

 in the National collection. 



Distribution. Western China ; North-east Thibet. 



This species very strongly resembles 8. dubiosata, but the 

 male has a fringe of long hair on vein 1 of hind wing below.
