In Snellen's opinion the A. Anita Hew. of which illustrations are given 

 by DE NiCEViLLE (pi. XXVII 5) and by Swinhoe (pi. 671, fig. i — 16) and 

 which Bethune Baker also mentions, belongs also to this species. 



A comparison of the 4 cT and the 5 $ in my possession leads me to the 

 same conclusion. There are males in which the upperside is entirely of brilliant 

 purple blue, others in which it is a darker blue, and yet others in which the 

 blue on the upperside is almost entirely replaced by brown. There are 9 in 

 which the colour of the upperside of the primaries Is bright dark blue or light 

 greenish blue or clear light blue. But the blue in all cf Is invariably surrounded 

 by a narrow, sometimes very narrow, darker band, and in all 9 by a very 

 broad one. The underside Is different in every specimen, but In the cT always 

 much more darkly mottled than in the 9, the colour of which Is there some- 

 times very light, while all 9 there display a dark line which runs slanting across 

 both wings and which Is absent in all (f . Neither are these differences of 

 colour to be connected with E. J. or W. J. The underside, the differences of 

 colour of which strongly remind us of those in Cyllo Leda L., indicates that 

 this is a species in which an evolutionary colour change is proceeding, which 

 may be recognized by the differences of colour and markings in the individuals.

The egg is described by Doherty as " large, coarse, overlaid with white, 

 roughly tubercular and Indented with spaces obscurely hexagonal". Larva and 

 pupa have been Illustrated by Swinhoe and described by de Nicevii.le after 

 Horsfield's illustrations. The larva is " of the usual Lycaenid shape, onlsclform, 

 with head small, second segment much larger, the segments gradually increasing 

 in width to about the seventh, then decreasing to the anal segment, which is 

 bluntly pointed, the constrictions between the segments fairly well marked ; a 

 few short bristly hairs on the sides of the body". The plant on which It feeds 

 is not mentioned. The pupa is " usually lengthened and attenuated, with head 

 rounded, thorax humped in the middle, abdominal segments very slender, the 

 tail sharply pointed". 



I include here the drawing of a larva from Java, the food plant of which 

 is also unkwown to me. It was onlsclform, the first part of the body, especially 

 in repose, longer and broader than the hinder part. The head is bent down and 

 concealed under the foremost segment, as is the case with many Lycaenid 

 larvae. The larva Is a handsome greenish yellow, with a dorsal, suprastigmatic 

 and infrastlgmatic stripe, all light blue, which stripes do not continue to the
