There was a nice series from Oiwake in Pryer’s collection. 
I obtained specimens at Gensan in July and at Hakodate in 
August. 
My collectors met with the species in all the localities in 
Western China that they visited, and also at Chang-yang: 
June and July. Alphéraky records it from the province of 
Szechuen, taken in August. 
In some of the specimens from Wa-shan and Che-tou the 
white markings are very narrow, and there is an entire 
absence of dark lines or patches. 
Distribution. N.W. Himalayas; Sikhim; Khdsis (Hamp- 
son); Amur; Japan; Yesso; Corea; Askold; Central and 
Western China.
