Acidalia nemoraria. 



Acidalia nemoraria, Hiibn., var. ?; Alph. Rom. sur Lep. vi. p. 54 

 (1892). 



Alpheraky records a male specimen from Ou-pin in the 

 province of Kan-sou : July. He states that the wings are 

 very white, and that the ochreous bands are more distinct, 

 especially on the secondaries, than in the European type. 



Distribution. Central and Eastern Europe ; Amur j 

 Western China. 



Acidalia nivearia, sp. n. 



Male. White. Primaries have three oblique pale ochreous 

 transverse lines ; the first of these is not well defined, but 

 the second and third are parallel and near together ; the costa 

 of primaries and outer marginal area of all the wings sparingly 

 sprinkled with minute black specks (only discernible under a 

 lens). Secondaries have two almost parallel pale ochreous 

 transverse lines and a black discal dot. Under surface white : 

 primaries suffused with fuscous on costal portion of basal half; 

 parallel transverse lines pale brown : secondaries have a pale 

 brown transverse line beyond the middle and a minute black 

 discal dot. 



Female. White, with minute black specks on costa of 

 primaries and outer marginal area of all the wings as in the 

 male ; the wings appear to be without transverse markings. 



Expanse, <$ 22, 9 18 millim. 



One example of each sex in Fryer's collection. 



Hab. Japan.

There were some specimens from Oiwake in Fryer's collec- 

 tion, and I took a nice series at Gensan in June and July. 

 Distribution. Europe; Amur; Corea; Japan. 



^Acidalia major aria, sp. n. 



Male. Allied to A. umbelaria, Hiibn. Whitish, powdered 

 with fuscous scales. Primaries have four pale brown trans- 

 verse lines, the first of which is elbowed below costa, the 

 second is oblique, the third and fourth (which are near to- 

 gether) are oblique and slightly wavy. Secondaries have 

 three transverse lines, which appear to be continuations of 

 the second, third, and fourth of primaries. Fringes whitish,
