Two examples only of this beautiful species have yet come to Europe; they were taken by 
Captain J. Smyth, of the 69th Regiment, after a day’s chase; and are the only ones he saw during 
his residence in Burmah. ‘They most nearly resemble P. Varuna, the male having the same large 
and remarkable folding of the hind wing.
