species is rare about Yokohama, but is more abuudaut iu the mountains ; it 

 occurs from May throughout the summer. He says : — " The female is very 

 seldom to be obtained. The male, which is ornamented exactly as iu the 

 preceding species [P. demetrius], is in its first brood often very diminutive, 

 and I have captured them less than half the size of the female specimen 

 figured. I have not yet found the larva. This species is specially adapted to 

 fertilizing lilies, the pollen from the flowers, which it frequently visits, 

 adhering to its long hind wings and tails." 



The male specimens in my collection range from 86-120 millim. in expanse, 

 and the largest female measures 134 millim. 



This insect does not appear to be common in China. I have received 

 specimens from Kiukiang, Ta-chien-lu, Wa-ssu-kow, and Pu-tsu-fong. Ober- 

 thiir's type of sccevola was from Boisduval's collection, and probably from 

 China. 



Dr. Staudinger curiously confounds this species with P. machaon. 

 Distribution. Central China ; Southern and Central Japan.

 arcuate. I'',xpanse of wings 5 inches 15 lines." {lintJer, I. c.)
