Burmah. B. M. 



We have thirty-three examples, representing wet-, inter- 

 mediate-, and dry-season forms ; the wet form is 1. meipona 

 and the dry /. moulmeinensis. Doubtless this is the Burmese 

 representative of the Indian /. frequens ; as a whole it is 

 somewhat smaller (though individuals of the same size 

 belonging to both species may be selected from a long series), 

 the orange belt of the primaries is more golden, more deeply 

 incised at the end of the cell, and, in the female, where it 

 becomes an orange or yellow band, it is more narrowly 

 bordered behind with black ; the border of the secondaries is 

 much narrower, almost disappearing in the extreme dry form, 

 which is also much more heavily and clearly marked with 

 ocelioid spots on the under surface than in /. frequens.

India, from Darjiling to the Western Provinces and south- 

 wards to the Neilgherries. 



Twenty-eight specimens are In the collection and one in 

 the Hewitson cabinet. 1. colaba is the wet-season form, 

 /. dharmsalce a dry form (probably occurring at the commence- 

 ment of the dry season), and /. ganduca the extreme dry 

 form. 



This butterfly can be distinguished from I. frequens by its 

 narrower, internally notched, and more or less macular hind- 

 wing outer border, which also tapers less towards anal angle, 

 and in the possession of an additional form of female (wholly 

 black and white above). I am doubtful whether it will be 

 possible to keep it distinct from /. pirenassa (of which no wet 

 form answering to the type is known to me).
