Several specimens from Yokohama in Fryer's collection. 



Mr. Smith took the species at Hakone in August, and 

 I captured some examples at Tsuruga in July and at Nikko 

 in September. 



A fairly constant species, but the discal markings of all 

 the wings and the marginal border of secondaries are subject 

 to modification. 



Distribution. Amur; Japan.

 there is a whitish line at end of the cell. Secondaries, which 

 are angled in middle of outer margin, have a broad oblique 

 whitish line. Fringes whitish. Under surface whitish, 

 strongly tinged with green on primaries ; the broad trans- 

 verse lines of upper surface are reproduced.

This species is somewhat similar to M. albovenaria^ Brem., 

 but the outer margins are not crenulate.
