the cycadae were always in company with a great many ants; it is possible 

 that a certain amount of symbiosis existed between them ; I did not, however, 

 investigate the matter. My descriptions of larva and pupa correspond well 

 with Moore's and the very minute one by de Nic^ville, although I have never 

 seen the bi-colouring of the full grown specimen, of which the latter speaks, 

 and which is also represented in Sw^in hoe's illustration. Both found the larvae 

 in Ceylon and Calcutta upon Cycadeae, and de Niceville expressly mentions 

 also "cultivated Cycadae (Cycas Revoluta) in gardens, eating the hardly-opened 

 shoots or fronds, thereby utterly destroying the appearance of the plant for 

 the year." They lived there in symbiosis with three kinds of ants, Pronolepsis 

 LoNGicoRNis Latr., Monomorium Speculare Mayr, and Cremarsoyaster Spec. 

 For., who presumably drive the full-grown larvae into their nests, there to 

 undergo their transformations, as the pupae are never found upon these plants.

The colour of the upperside of this common and easily distinguished little 

 butterfly varies in the 9 very greatly. It is usually brown, sometimes very 

 light and uniform, but usually rather darker and lighter in the middle; in 

 some specimens this middle part is light blue surrounded by a broad pale 

 black edge. Moreover in both sexes there is a considerable difference in size 

 between the individuals, as is usually the case with Lycaenae. There is no 

 difference discernible between specimens from W. J. and E. J. or between those 

 from the dry or the wet season. Everywhere and in all seasons the individuals 

 were amongst themselves. The underside is the same in both sexes.
