females, however, differ more conspicuously, though all the forms run 
into one another. 
The figures on Plate II represent a typical female of J. marianne 
taken at Berhampore, Ganjam, in July (fig. 17), a typical female of 
I. meridionalis taken in Mysore in November (fig. 18), and a typical 
female of J. agniverna taken at Berhampore, Ganjam, in February 
(fig. 19), all from specimens taken by myself. 
I, nola has as yet only been recorded from Mahableshwar. It appears 
to be a quite distinct species. Both seasonal forms are represented in 
the collection at the British Museum. Other named forms of Jzias 
recorded from the Indian region, which are either not named in the 
British Museum, or about which I neglected to take notes, are I. bebryce, 
Hiibner, J. anewibia, Hiibner, I. sesta, Fabricius, I. rhexia, Fabricius, 
I, pirithous, Fabricius, I. meipona, Grose-Smith, J. birdi, Distant, 
I. ganduca, Moore, I. familiaris, Butler, and I. satadra, Moore. 
TERIAS. 
The genus Terias has been more hardly dealt with than any other in 
the matter of bad species, chiefly owing to the fact that seasonal variation 
is very much developed in the species of the T. hecabe group, of which 
there are twenty-two named forms in the collection at the British 
Museum and almost as many unnamed ; how many of these will turn 
out to be good species when they have been bred is rather doubtful, 
but probably it will be found that not more than four species of this 
group occur within Indian limits. 
The Indian species of Terias fall naturally into four groups which 
can be readily separated. The chief point of separation is the presence, 
absence, or form of the glandular streak in the male—a point to 
which attention was first drawn by Mr. de Nicéville in a paper on the 
Butterflies of Calcutta, published in the Journal of the Asiatic Society 
of Bengal for 1885. Apparently no mention of these characters has 
been made by subsequent authors, though their presence or absence is 
a point of great systematic importance. 
The four groups referred to above may be compared as follows :— 
A.—Male, with a greyish glandular streak on either side of 
submedian nervure at base of forewing on underside. No 
male-mark on hindwing. A reniform spot on disco- 
cellulars of forewing on underside. 
T. HECABE group.
