Sumatra. $ from G. and S. coll. B. M. 



Our single example belongs to the wet-season form, but 

 the type was a dry form. We have what I believe to be the 

 male intermediate form from Salanga.

Burmah, High Island, Mergui. B. M. 



We have fifteen examples, seven of which (including the 

 types of the species) were presented by Messrs. Godman and 

 Salvin. /. latifasciatus was figured from an intermediate 

 female, I. verna was described from a dry-season pair. A 

 male from Mergui in the collection may perhaps be a curious 

 aberration of this species. 



Group 5. (Type /. marianne.) 



I am quite satisfied that the late Capt. Watson was correct 

 in his view of the species of this group; all the seasonal 

 forms show ocellated markings on the under surface, but 

 they become emphasized in the dry season, whilst the black 

 belt across the primaries on the upper surface and the black 

 border to the secondaries are reduced.
