430 Mr. H. J. Elwes’ catalogue of the 
and the colour a shade paler than the male, but other- 
wise like it. 
416. Papilio polymnestor. 
Papilio polymnestor, Cram., Pap. Ex., i., t. 53.4 (1779). 
A single specimen only of this species was taken in 
1887 by Moller’s collectors, probably a straggler from the 
plains. 
417. Papilio clytia. 
Papilio Clytia, Linn., Mus. Ulv., p. 296 (1764). 
Papilio dissimilis, Tuinn., l. ¢., p. 801. 
A common species from the plains up to 3000 ft., and 
occurs from March till November. I am assured by 
Mr. Aitken, of Bombay, who has bred this species, that 
clytia and panope are produced from similar larve found 
together, and are probably two forms of one species.* 
418. Papilio panope. 
Papilio panope, Linn., Syst. Nat., i., 2, p. 782 (1767). 
Common at the same elevation and same season as 
the last. 
2419. Papilio megarus. 
Papilio megarus, Westw., Arc. Ent., ii., t. 72 (1845). 
I have no direct evidence of the existence of this spe- 
cies in Sikkim, and though a single specimen of it in my 
old collection bears a Sikkim label, Moller has never 
obtained it there. 
420. Papilio xenocles. 
Papilio xenocles, Doubl., Gray, Zool. Mise., p. 74 
(1842) ; Hew., Gen. D. L., t. i., fig. 2. 
A common species in the lower valleys up to 3000 ft., 
** In the ‘ Journal’ of the Bombay Natural History Society, No. 1, 
vol, ii., 1887, p. 37, the following passage occurs :—‘‘ Among the 
larvie of the last species (dissimilis) which I reared was one not 
distinguishable from the rest, which to my astonishment turned 
into this (? panope). I am quite satisfied that the two are one 
species. I have never recognised another specimen of panope in 
this Presidency, but have little doubt that I have often let it pass 
for 1. core” (Aitken).
