FHeterocera from China, Japan, and Corea. 265 
I met with this very variable species in October at 
Nikko and my native collector obtained it in the island 
of Kiushiu., 
Col. Swinhoe considers his castanea to be a pale form of 
C. japonica, and in this opinion I quite concur. The 
form is not an uncommon one.

Neoris jonasi, Kirby, Cat. Lep. Het., p. 761 (1892). 
I met with this species at Oiwake and Nikko in 
September and October. There was a fine series from 
Yokohama in Pryer’s collection. 
Staudinger (Rom. sur. Lép., vi, p. 325) suggests that 
the Japanese and Amurland forms of this species should 
be known as var. jonasi, as they differ from the type, 
which is from Kiachta, in being smaller and darker. The 
Japanese specimens in my series are larger and more 
tinted with olivaceous than those from Amurland. 
Distribution, SIBERIA; AMURLAND; JAPAN.
