I have an extensive series of this species which com- 
prises specimens from Nagahama, Nagasaki, Tsuruga, 
Oiwake, Ningpo, Kiukiang, Chang-yang, Foochau, Gensan, 
Chia-ting-fu, Huang-mu-chang, and the province of Kwei- 
chow. Pryer gives Ohoyama, Fujisan, and Kanosan as 
other Japanese localities. 
The Ningpo specimens agree with germana which, as 
Felder states, differs from thelebus in being smaller in size 
and in having narrower yellow bands on the abdomen.

Originally described from Kiukiang. I have since 
received a number of specimens from Moupin and single 
examples from Chia-ting-fu and the province of Kwei- 
chow. Occurs in June and July. 
There is some variation in the size of the hyaline spots 
and in some examples there are two subapical spots. The 
only specimen I have seen from Kwei-chow has this
