This species is very common in Java. The specimens differ very much 

 in size, without the season in which they were caught having any influence 

 upon it. According to Snellen the d cannot be distinguished from European 

 specimens but the 9 from Java is lighter and more silvery-blue in colour on 

 the upperside of the primaries. I can see no difference between specimens 

 from W. J. and E. J. The underside is the same in both sexes. 



The larva lives inside the pods of the common Pisum Sativum L. as 

 well as the pods of klongkang (Psophocarpus Tetragonolobus D. C), katjang 

 toenggak and pandjang (Vigma Catjang Walp) and katjang arab (Phaseolus 

 LUNATUS L.) where it feeds upon the inside of the pod, and like the pupa, it 

 is of the usual Lycaenid shape. It is pale red-brown, with black marbling and 

 a dark dorsal line ; also sometimes reddish green with black stigmata. 



According to de Niceville, at Calcutta the larva lives upon the flowers 

 and inside the pods of Crotolaria striata D. C, and in Europe upon the 

 flowers of Crotolaria Capensis and at Calcutta in symbiosis with three species 

 of ants, Camponotus Rufipes Drury, (Sylvaticus F.), subspecies Compressus F., 

 Tapinoma Melanocephalum F. and Prenolepis obscura Mayr (var. Clandestina 

 Mayr). Although I often found the larvae in Java, I never observed this symbiosis. 



The pupa is greyish green, or yellowish brown, with small black spots. 

 A pupa of April 14''" yielded a butterfly on April 2}^^ . As in the pods the 

 larva lives with the larva of L. Cnejus F. which resembles it very closely; 

 this gave rise to a good deal of confusion in observations.

This species is minutely described by Snellen, in the above quoted work, 

 from a fresh 6 specimen which I caught; I give an illustration of it here. 



The particulars of this species, as noted by Snellen, are as follows: 

 The wings correspond in form to those of the common European Lycaena; 

 the colour of the upperside, of the five closely related species, is in Glauca 

 the most greyish, with only a faint silky sheen. Towards the outer margin 

 of the wings the ground is somewhat darker. The fringe-line is blackish grey, 

 at the inner angle of the secondaries there is no indication of black spots 

 visible. The fringe is grey with lighter outer half, on the secondaries almost
