This Butterfly is common in India and the adjacent islands ; 

 it measures about an inch and a half across the wings, which 

 are white, tinged with pale blue at the base, and with blackish 

 borders, broader in the female than in the male, which are 

 spotted with white on the hind-wings. There are large black 

 lunules at the end of the cell, and some large black spots and 

 markings, partly connected with the border. The under side 

 is white with some heavy black stripes and spots towards the 

 base, and three rows of black sub-marginal spots. It flies near 

 the ground, and frequently settles among grass and low 

 plants. 



The genera Pepliphorus and Thysonotis, Hiibner, include a 

 number of beautiful and closely-allied species, found through- 

 out the Austro-Malayan Region ; they are extremely numerous 

 in New Guinea and the adjacent islands. These species 

 measure about an inch and a half across the wings, which 

 are of a light blue in the males, and brown in the females, 

 usually with a white band, broadest at the inner margin 

 of the hind-wings, and diminishing towards the costa of 

 the fore-wings ; on the under surface the borders of the 

 wings are broadly black. In the species of Peplipharus^ the 

 type of which is Papilio cyanea, Cramer, there is a marginal 

 row of eyes on the under side of the hind-wings. In Thyso* 

 notis (type, Papilio Jams, Cramer), the black borders of the 

 under side are transversed by broad stripes of metallic green or 

 blue.
