The type in the National Collection appears to be a female. The male 
only differs in being blacker and in having a very conspicuous broad short 
glandular patch on the primaries. 
I have a series from Oiwake and Yesso. Pryer records the species from 
Nikko and Assama-Yama, and states that it is a scarce insect.
