SIKKIM: Ataran Valley (Col. C. T. Bingham); 1 2 (type). 
A second female from the Runjitt Valley, iv. 1894 (Col. 
Bingham), is rather smaller, and shows no dark streaks 
above M and Cu, but is certainly conspecific. The colour of 
the femora will at once distinguish it from all other described 
species. (Brunetti mistakenly attributes a similar coloration 
to P. insignis, Meij.)
