Heterocera from China, Japan, and Corea. 119 



Occurs at Yokoharaa, Oiwake, and Tokio. 



The series in Fryer's collection comprised eight males 

 and seven females, four of the latter have well developed 

 wings, but the other three have dwarfed wings, although 

 the markings thereon are a reproduction in miniature of 

 those on the wings of the fully-developed females. 



Habitat. Japan. 



411. Orgyia leechi. 



Orgyia 2yrisca, Leech, Entom., xxiii, p. Ill (1890), 

 Notolophus Icechii, Kirby, Cat. Lep. Het, i, p. 495 (1892). 



Apjiears to be common at Chang-yang ; I also received 

 specimens from Ship-y-shan and Ichang, and from most 

 of the localities in Western China that were visited by 

 my collectors. 



As " prisca" had been previously used in Orgyia, Mr. 

 Kirby has renamed this species. Staudinger (Rom. sur 

 Lep., vi, p. 803) states that he has an example from 

 Tschi-fu of a species allied to 0. ericie ; this may be iden-

Habitat. Central and Western China.

 Ichang, and Ship-y-shan. Those from the two localities 

 last named are bright reddish orange. 



Of the female, which sex has not been previously de- 

 scribed so far as I can ascertain, I have four specimens
