E. J. Province of Banyouwangy ; Kedyry (64). 



This species is not uncommon in the lower districts of Java. The size 

 differs, the largest specimen that I possess is from E. Java.

This species also differs in size. But in my eleven specimens I cannot 

 find those differences of marking, neither that arising from sex, nor that from 

 difference of season, which Swinhoe reproduces, mine being all marked alike.

I had the larva several times, but was not informed with certainty of its 

 food-plant. According to my information it was supposed to eat the leaves of 

 the plant which at Batavia is called bidara outan (presumably Zizyphus Jujuba 

 Lam) or also douri tjandel. It is of an arched long oval shape, so that when 

 it walks, all the legs can be distinctly seen, which is not the case with most 

 Lycaena larvae. In colour it is green, divided into different shades. There is 

 a very dark green dorsal stripe, while on both sides the green is very light in 

 colour; whitish green transverse lines show the divisions between the segments. 



It is covered with very short hairs, longer at the sides, which are some- 

 times reddish and sometimes white. The pupa is light green, with some dark 

 dorsal marbling ; from a pupa formed on March 5''' a butterfly was produced
