g. Type from Yoshino, Yamato, August, 1900. 
A series of sixteen male specimens taken at Yoshino, 
Yamato, in June, July, August and September, 1899, 
1901, also one specimen from Nikko, August, 1893. 
The series varies in expanse from 30 to 34 mm. I have 
never taken a female specimen. This species shows some 
variation in the fuscous suffusion of the forewings. The 
forewings of one specimen are almost uniformly fuscous, 
the ochreous basal patch is obsolete, the antemedial line 
is only faintly traceable, and the white postmedial line 
stands out in bold relief on the fuscous ground.
