LEPIDOPTERA INDIO A. 
rest remain till June. Do the butterflies which come out in August and March lay 
eggs, and, if so, what becomes of them ? 
The larva of this species is not so thick proportionally at the fourth segment as 
those of P. Doson , Sarpedon and Agamemnon , and is somewhat quadrangular. It 
has four pairs of spines, which are small, but sharp. The most usual colour is 
black, banded on the sides with narrow white stripes, except on the first three or 
four segments and the last, on which there is more or less rusty-red ; but the shade 
varies very much, and. in some the ground-colour is green. The pupa has the 
usual horn which characterizes this group, and also two short processes on the head, 
and is of some shade of earthy-brown. It is attached by the tail and a close band 
in crevices, or under stones and roots. We furnished our cages with bits of broken 
tiles, but several of the larvae preferred the old clay nest of a wasp, into the empty 
cells of which they crept. This curious habit is of course connected with the hyber¬ 
nation which the majority of the pupae undergo. Along with our larvae of P. Nomius 
we found some of P. Agamemnon and P. Doson , and it is remarkable that while very 
many of these had been attacked by a large parasitic fly, the grub of which ate its 
way out and fell to the ground after the pupa had formed, P. Nomius, so much more 
conspicuous and feeding on the same tree, seemed to eojoy entire immunity from the 
pest. 55 £C We have since proved that P. Nomius remains for more than half the year, 
from the end of July till at least March, or oftener May, in the pupa state under 
stones and roots ” (J. Davidson and E. EE Aitkeu, Journ. Bombay lS r . H. Soc. 
1890, p. 364, id. 1896, p. 57a). 
Distribution, Habits, etc. —In Ceylon, Mr. F. M. Mackwood records it as being 
found in the “ low country only, and principally in the Northern provinces. Very 
scarce. Captain Hutchison obtained it in the Eastern province, in the plains and 
forest, in August. Taken only on one occasion, on a journey from Kandy to Trin- 
cornalie, associated with Pap. Antiphates and Doson , sitting in numbers on damp 
places on the road, dense forest being on both sides. Captain Wade also took it 
at Trincomalie” (Lep. Ceylon, i. 142). Dr. N. Manders found it “ common and 
frequently abundant in the North Central Province and on the Trincomalie side of 
the Island. It is fond of setting in large numbers together on damp patches of sand. 
It flies in July and August, and again at the end of the year ” (Journ. As. Soc. Beng. 
1899, 223). Col. J. W. Yerbury obtained it at “ Tamblegam and Trincomalie in 
September” (MS. Notes), In South India, Mr. H. S. Ferguson found it “ rare in 
Travancore. One specimen only being taken at the foot of the Ashambu Hills ” 
(Journ. Bombay N. H. S. 1891, 16). Mr. G. F. Hampson obtained “ one specimen 
only in the Nilgiris, at 1,000 feet elevation 5 ’ (Journ. As. Soc. Beng. 1888,364). 
Mrs. Hamilton found and reared the larva in Saugor, in July, 1852, describing it as 
dark blue with brown ends and green underneath, six anterior and two posterior
