on March i 2''^. Bingham and Swinhoe describe the larva and pupa of British 

 India, after Davidson Bell and Aitkin; the larva there too lives upon Zizyphus 

 JujUBA. Their description is about the same as mine. Swinhoe gives an 

 illustration of both, in my opinion not a successful one. My reproductions are 

 somewhat enlarged, but as such fairly satisfactory.

The butterfly is very common in Batavia. I see no difference between 

 a male from E. Java and those from Batavia. The male in Batavia is some- 

 times lighter and sometimes darker, and this is the .case with specimens found 

 both in the rainy season and in the driest period of the dry season ; seasonal 

 differences are not to be observed. In this species also there is a difference 

 in size between individuals. The blue metallic shimmes on the upperside of 

 the male is absent in some specimens. 



The larva, on bidara (Zizyphus Jujuba Lam.) is yellowish green, with a dorsal 

 stripe of a lighter shade, next to which the green is darker than elsewhere. 

 The division between the segments is shown by light yellowish green cross lines. 

 When magnified, numerous white dots are seen on the larva, and it is seen 

 to be covered by short white or reddish hairs, which also stick out along the 

 sides. It differs very greatly in size, the largest specimens were 13 mms long 

 and 5 mms broad. The pupa, attached by a girdle-thread, is sometimes light and 

 sometimes dirty green, with a brown dorsal line ; it is further more or less 

 speckled with brown. A pupa of May 16''^ gave a butterfly on May 23'^'', one 

 of May 1 7"\ on May 24'"^.
