This form was described upon specimens in Mr. Moore's collection 

 from Mynpuri, N.W. Punjab ; in the Museum we have a pair from 

 Kurrachee, presented, along with specimens of T. dynamene, by Col. 

 Swinhoe ; now again a single male comes from Aden in company 

 with T. dynamene. I think therefore that the distinctness of this 

 form from the latter must be regarded as extremely doubtful, unless 

 it can be shown hy breeding that it is a different species. At the 

 same time, the two forms are sufficiently dissimilar to leave the 

 question of their specific identity an open one for the present.

The males are large, and therefore belong to the variety figured by 

 Klug ; the females show every gradation from the pure yellow form 

 of Klug's figure to a form almost exactly agreeing with the male ; 

 there is also a saffron-yellow variety, and a variety of a creamy-white 

 colour, slightly suffused with salmon in the centre and along the 

 costa of the primaries.

The fact that these Butterflies are all caught flying together, taken 

 in conjunction with the slight difference which separates the one 

 from the other, seems to me to indicate that T. miriam is only an 

 under-coloured variety of T. pleione : its sole distinction is that the
