I. pygmea, which represents the extreme of the dry-season form, 
is only represented in the British Museum from North-western India 
(October, November, December) ; but there are perfectly typical exam- 
ples of it in my collection from several localities in Burma, taken in 
January, besides numerous intermediates between typical I. pygmea 
and typical I. pyrenassa. 
I. pyrenassa is in the British Museum Collection from Dharmsala, 
Bombay, Barrackpore, Darjeeling, Bengal, the Nilgiris, Campbellpore, 
Attock and Kangra ; and in my collection, from Madras, the Nilgiris, 
Mysore, Ganjam, and numerous localities in Burma. I have not found 
this form so common in Burma as typical J. pyrene, and some specimens 
are distinctly intermediate with J. moulmeinensis, having a few specks 
of orange in the cell below the disco-cellular spot on one wing and 
none on the other. These puzzling specimens apparently do not occur 
out of Burma, where they show a distinct transition to I. moulmeinensis 
and thus to I. pyrene and I. evippe. 
The figures on Plate II represent a male of the rainy-season form 
taken in Upper Tenasserim in May (fig. 21), a male of the ordinary 
dry-season form taken in the Karen Hills, Burma, in December 
(fig. 20), and a male of the extreme dry-season form, 2.¢., J. pygmca, 
taken in the Yaw District, Upper Burma, in February (fig. 22). 
This latter is the ordinary dry-season form in dry districts, where the 
rainy-season form is, on the other hand, not so pronounced ; the specimen 
figured is absolutely typical even in size, though, as has been pointed 
out by Mr, Butler, the small size of this form is by no means constant, 
I regret I took no notes about I. latifasciatus when at home, but it 
represents the utmost extreme of the rainy-season form of either 
I. pyrene or I. pyrenassa, probably the former. 
I. citrina, which I am unable to distinguish from J. pallida, Moore, 
is in the British Museum from Tenasserim and High Island, Mergui, 
and in my collection from Tenasserim. It appears to be a pale form 
of I. pyrene and is probably insular, its head-quarters being in the 
Mergui Archipelago, while it straggles occasionally on to the adjacent 
continent. 
I. verna, which is in the British Museum from High Island, Mergui, 
and is in my collection from Tenasserim, bears exactly the same rela- 
tion to I. pyrenassa that J. citrina does to I. pyrene.
