great confusion between these and the related species, arising in a great measure 

 from the fact that the differences between the species are usually very slight, 

 and therefore demand very accurate illustrations, while most of these are by no 

 means accurate. I shall endeavour to meet this difficulty by giving careful 

 reproductions. Orseis cf usually has a large part of the upperside dark blue, 

 but sometimes also dark brown; the underside is often dark, with a intense 

 purple metallic shine, but is also sometimes of a much lighter colour without 

 metallic shimmer. The $ is on the upperside more or less dark grey and on 

 the underside grey also, sometimes lighter in colour and always without metallic 

 shine. The markings on the underside are the same in both sexes.

The larvae feed on the flowers of tjintc, f/i)itamanis or lai ajam (Lantana 

 Camara L.), also on young raviboidan leaves (Nepheliujvi Lappaceum L.), 

 and Albizzia Stipulata Boiv., as well as other leaves. They are very light 

 green, but the i*' abdominal and the i i'"^ segment are dark brown, which 

 however only appears at the lest moulting and is not equally distinct in all 

 larvae. The back is very angular, difficult to describe, each segment has on 

 each side a spike. The pupa is of the usual Lycaenid form, mottled dark brown 

 or dark green, with very slighdy pointed tail end ; it is attached by a girdle- 

 thread. A pupa of July 2°^ produced a butterfly on July 1 2^*".

Varuna cf can hardly be distinguished on the upperside from the former 

 species, the 9 also resemble each other greatly in this respect, although Varuna 

 is lighter and more greyish. But the marking on the underside differs very 

 distinctly from that of Orseis ; it consists of much thicker lines, especially on 

 the underside of the primaries, which sometimes even partially melt into one and 

 thus form a patch. There is individual variety in this, but always the same system.
