My collectors appear to have met with this species 
commonly at Wa-shan in July; they also obtained 
specimens in the same month at Ta-chien-lu, Huang-mu- 
chang, Ni-tou, and Chia-kou-ho. 
In the Huang-mu-chang example, the hyaline spots in 
the interno-median interspace are united. I propose the 
varietal name conflwens for this form. 
Distribution. WESTERN and NoRTH-EASTERN CaINA.

Occurs fairly commonly at Kiukiang in June; I have 
also received specimens taken in the same month in

The Kwei-chow specimens have much larger hyaline 
spots than the other examples comprised in the series.
