SYNONYMY OF SOME SPECIES OF INDIAN PIERINZE. 505 
Typical J. evippe is a very large form, in which the orange of the 
apical patch enters largely into the cell and extends across its whole 
breadth. This form appears to be confined to the north-east of the 
Indian region, and is in the British Museum from Nepal, Darjeeling, 
and Manipur. The figures of the dry- (fig. 28) and rainy-season 
(fig. 27) forms on Plate II are taken from two specimens in my collec- 
tion from Assam. 
Typical I. pyrene differs from I. evippe in being smaller, and in the 
orange apical patch on the forewing entering the cell both above and 
below the black spot onthe disco-cellulars, but not, or hardly, entirely 
surrounding the black spot. 
I, moulmeznensis, Moore, only differs in the apical orange patch 
entering the cell toa rather less extent below the black spot. Both 
typical I. pyrene and typical J. moulmeinensis occur commonly 
throughout Burma, but apparently do not extend west of Assam. 
The two forms run into one another, and are not separable, The dry- 
and rainy-season forms are figured on Plate II, figs. 28 and 25, the 
former from a male taken in the Yaw District, Upper Burma, in 
January, and the latter from amale taken in the same locality in 
September. 
I. pyrenassa is a form in which the apical orange patch only 
extends into the cell above the black spot on the disco-cellulars ; this 
is the common yellow Iwias which occurs throughout the Indian region 
wherever yellow forms of Jxias are found (except in the Andamans 
and Ceylon). It would, therefore, appear to be the parent form, other 
yellow forms being local modifications of it. It has received numerous 
names, having been called J. dharmsale, I. frequens, and I, watti by 
Butler, J. colaba and I. alana by Swinhoe, and the extreme of the dry- 
season form having been named I. pyymea by Moore. I am quite 
unable to say how the first four of these forms are supposed to differ 
from typical I. pyrenassa, but am quite certain if the specimens 
arranged above each name in the National Collection were mixed 
up and the labels removed, that no one would be able to re- 
arrange them as they are now arranged. [. alana I have not seen, 
but there is not the faintest doubt that it is a form of J. pyrenassa, 
occurring ina more rainy time of year than J. colaba, with which it 
is compared by its describer.
