of davidis as figured by Oberthiir agrees better with that of P. nomion. The 
dark abdominal border of secondaries agrees exactly with that of P. nomion, 
and is quite different to that of P. honrathi. Moreover, Oberthiir informs 
me in reply to my inquiry on the point that the legs and hairs of the under 
surface of the body of davidis are not black as they are in P. honrathi. The 
range, too, of honrathi appears to be extremely restricted, being confined to 
a limited district south-east of Samarkand ; nomion, on the other hand, is 
distributed throughout the greater part of North-east Asia. I am inclined, 
therefore, to consider davidis as a form of P. nomion. 
Grum-Grshimailo described a small bright form of P. nomion from Koko- 
noor and the Dshachar Mountains as var. nomins *. 
My collectors failed to meet with P. nomion in any part of China that they 
visited.
