428 Mr. H. J. Elwes’ catalogue of the 
as arule. I have sometimes seen it in the forest-paths, 
where it occasionally settles. The female is also rare, 
but does not differ from the male, except in being rather 
larger. 
407. Papilio ganesa. 
Papilio ganesa, Doubl., Gray, Zool. Mise., p. 73 (1842) ; 
Gray, Cat. Lep. B. M., 1., p. 16, t. iii. ) 
This is an inhabitant of the lower valleys, like P. paris, 
and occurs from April to December in successive broods, 
whilst arcturus and krishna are probably single-brooded. 
408. Papilio androgeus. 
Papilio androgeus, Cram., Pap. Ex., t. 91, f. a, b (1779). 
Common in the lower valleys, and found as high as 
4 or 5000 ft. from April until December. The common 
form of female in Sikkim is tailed, with a considerable 
amount of white in and beyond the cel] of the hind wing ; 
but tailless females are also found without any white 
markings, and others with a broad white patch on the 
hinder margin of the fore wing. 
409. Papilio protenor. 
Papilio protenor, Cram., Pap. Ex., i., t. 49 (1779). 
Moller records this species as occurring from 2 to 
3000 ft., and from April until October; but it occurs at 
much higher elevations in the N.W. Himalaya, and in 
Khasia I have seen it up to at least 6000 ft. It is not, 
however, so common in Sikkim as in some other parts 
of the Himalaya, and the female is decidedly rare. I 
have never taken it myself in Sikkim. 
410. Papilio Rhetenor. 
Papilio Rhetenor, Westw., Arc. Ent., i., t. xvi. (1842). 
? Papilio Icarius, Westw., Cab. Or. Ent., t. 2 (1848). 
Found not uncommonly in the lower valleys, and up 
to 5 or 6000 ft. from April to October. Two forms of 
the male exist, which I am not able to separate, except 
by the colour of the hind margin of the fore wing, which 
in one form is more or less overlaid with grey or white
