Lepidoptera of Sikkim. 335 
been noticed, and which is perhaps analogous, if not iden- 
tical in character, with the pouch in the genus Parnassius. 
Some very fresh and apparently virgin females, which I 
took in the Khasias, had not this appendage as yet de- 
veloped, and it will be interesting to have closer observa- 
tions as to whether it is produced during coitus, as in 
- Parnassius, or not. 
96. Telchinia viole. 
Papilio viole, Fab., Syst. Ent., p. 460 (1775). 
Telchinia viole, Butt. Ind., i., p. 820, cut. 
Stated by Marshall and de Nicéville to occur not 
uncommonly in Sikkim, but not included in Méller’s 
Catalogue, and I have no specimens from this country. 
If it really is found it is probably only as a straggler 
from the plains. 
97. Hrgolis merione. 
Papilio merione, Cram., Pap. Ex., ii., t. exliv., fig. c, H 
(1777). 
Ergolis merione, Butt. Ind., ii., p. 8, t. xviii., fig. 70,3. 
A common species at low elevations, and more or less 
throughout the year. 
98. Hrgolts ariadne. 
Papilio ariadne, Linn., Syst. Nat., i., p. 778 (1767) ; 
Bubiaind.; i... 20. 
Rarer than merione, but found occasionally up to 
5000 ft. throughout the year. 
99. Huripus consimilis. 
Diadema consimilis, Westw., Gen. Di. Lep., ii., p. 281, 
? (1850). 
Euripus consimilis, W. Mason, J. A. 8. B., 1881, pt. ii, 
p28, triv.cie. 3; 9 > Butt. Ind. an pease: 
This species rarely occurs in the hills, but in the 
Terai, and as far out in the plains as Jelpigori, it has 
been taken by Messrs. Knyvett and Moller in July, 
August, and December.
