Specimens from Yokohama and Oiwake in Pryer’s col- 
lection. I obtained the species at Gensan in June and 
July. Butler’s type was from Hakodate. 
The species varies in the tone of the ground colour. 
The Gensan examples are paler than those from Japan 
but the pink tinge is stronger than in the specimens from 
Amurland figured by Staudinger. The markings are 
identical in all the specimens.
