vii, fig. 8 (1880). 
There were several specimens in Pryer’s collection. I 
bred a male specimen in June, 1887, from a larva found 
at Gensan in 1886. 
As Pryer points out in his catalogue the larva, which 
feeds on willow, does not differ at all fromEuropean ex- 
amples. Graeser makes a similar remark concerning the 
caterpillar in Amurland. 
Felina and askolda are not worth retaining even as 
varietal names as similar forms can be found in any 
representative series from Europe.

SX OO (LS 1iy): 
Menciana, Moore, appears to be a good local form of D. 
erminea. The ground colour of the primaries is grey 
slightly tinged with violet, and the marking are generally 
better defined than in the type form. I met with this 
form at Shanghai and Foochau, and I have received speci- 
mens from Omei-shan. A native collector in Japan sent 
me one example, obtained at Hakodate, which agrees with
