Pryer had six specimens from Yokohama in his collection, 

 under the name P. gamma, which are referahle to this 

 species. I have received examples from Moupin, Chou- 

 pin-sa, and Chia-kou-ho ; Alpheraky records one from 

 Choui-Tchin-Pou, in the province of Setchouen. 



Staudinger''(Rom. sur Lep., vi, p. 549) records a specimen 

 of P. gamma from Amurland. I have not seen an example 

 of this latter species from any part of Eastern Asia where 

 it seeais to be replaced by P. nigrisigna.
