There were specimens from Yokohama, Oiwake, and 

 Yesso in Fryer's collection. I obtained examples at 

 Fushiki in the month of July, and I have received the 

 species from Gensan, Ship-y-shan, Omei-shan, Chia-kou-ho, 

 and the province of Kwei-chow. 



Some of the males have two fuscous spots on the inner 

 margin of primaries ; others have a third spot placed on 

 costa immediately over, and almost uniting with, that 

 nearest the base on inner margin ; one example has a 

 fourth spot (subapical). Some of the females also have 

 one or both spots on inner margin, but these are not so well 

 defined as in the males. 



P. virguncula, Walk., which Hampson (/. c, p. 485) 

 includes as a form of P. xanthorrhoea, Koll., is probably 

 only a form of P. similis.

Two male specimens from Moupin taken in June. 

 These have the pectinations of the antennae almost black,

 Hampson considers to be a form of P. xanthorrhoea.
