A male and female in coll. Rothschild, from Koko-nor, Tibet, expand only 23 mm. 

 and 25 mm. respectively. We have not had an opportunity of comparing the male 

 genitalia of this small form with those of specimens of normal size.

Leech states that he has specimens intermediate between A. tibetana and subhyalina. 

 We have seen no specimens from Japan, but three males from the Khasia hills, 

 procured from Mr. Doncaster, are undoubtedly subhyalina.
