from China j Japan, and Corea* 645 



received the species from Kiukiang, and from several 

 localities in Western China. 



Distribution. Europe; Altai; Amur; Corea; Japan; 

 Yesso ; Central and Western China. 



In my series of this species from China, Japan, and Corea 

 there are specimens which exactly agree with typical pro- 

 cellata; others are identical with inquinata, Butl. ; and others, 

 again, are almost unicolorous fuliginous brown. All these 

 forms are connected by intergrades. 



Cidaria postalbaria, sp. n. 



Primaries fuscous brown ; basal patch and central fascia 

 darker, the latter intersected by a pale line ; the basal patch 

 is outwardly and the fascia inwardly bordered by a pale line ; 

 outer margin suffused with dusky ; submarginal line indi- 

 cated by a white spot about the middle, one towards apex 

 and a pale mark at outer angle. Secondaries white, suffused 

 with smoky on the abdominal area, and with some black 

 clouding about anal angle. Under surface fuscous grey on 

 primaries, whiter on secondaries; there is a pale band beyond 

 the middle on all the wings, this is clearly defined on its 

 inner edge by a blackish line, which is elbowed about the 

 middle of its length on primaries, and is crenulate on second- 

 aries, the outer edge is diffuse ; submarginal line of primaries 

 represented by whitish dots, the largest about the middle. 

 Fringes : of primaries agree with the ground-colour ; of 

 secondaries greyish marked with smoky grey. 



Expanse 34-40 millim. 



Several specimens, including both sexes, from Pu-tsu-fong, 

 Omei-shan, Chia-kou-ho, and one female from Chang-yang :

There were some specimens from Yokohama in Pryer's 

 collection, and my native collector obtained the species in the 

 island of Kiushiu. 



Several examples, including both sexes, were received from 

 Chang-yang; these were taken in July, and range from 

 26-34 millim in expanse. The species also occurred at Ta- 

 chien-lu, Omei-shan, Chia-ting-fu, Chia-kou-ho, Pu-tsu-fong, 

 and How-kow in July; the largest of these specimens
