from China, Japan, and Corea. 565 



In the male from Ta-chien-lu and the female from Pu-tsu- 

 fong the central fascia is only slightly angulated and not 

 interrupted below the middle. Possibly these specimens 

 may represent the more usual form of the species. I have, 

 however, described the Pu-tsu-fong male because it is in 

 much better condition than the others.

I obtained specimens at Tsuruga and Gensan in July, and 

 my native collector at Hakodate in the same month. There 

 were specimens from Oiwake and Yesso in Pryer's collection, 

 and my collectors met with the species in most of the 

 localities in Western China, and also at Chang-yang. 



Distribution. Europe; Ural; E.Siberia; Amur; Corea; 

 Japan ; Yesso ; Central and Western China ; Sikhim. 



In China and Japan this species is generally represented 

 by cerosa, Butl., which is identical with inextricata, Walk., 

 but I have typical specimens from Hakodate, Omei-shan, 

 and Chia-kow-ho. 



Eustroma melancholica.

 111. Typ. Lep. Het. iii. p. 58, pi. Iv. fig. 6 (1879). 



Five female specimens from Yokohama, Oiwake, Gifu, and 

 Yesso in Pryer's collection. I obtained an example of each 

 sex at Hakodate in August. 



Tlie variation in marking is very similar to that which 

 obtains in C. silaceata. 



Only one specimen has been received by me from China. 

 This is a male, taken at Pu-tsu-fong in July ; it has the 

 ground-colour suffused with brown and the markings are 

 darker ; the pencil of hair on underside is dark brown ; mea- 

 sures 50 millim. in expanse, and in form agrees with the 

 insulata form of Cidaria silaceata. 



I propose the name brunnearia for this form. 



Distribution. Japan; Yesso; Corea; Western China. 



Eustroma delecta.
