434 Mr. H. J. Elwes’ catalogue of the 
428. Papilio anticrates. 
Papilio anticrates, Doubl., Ann. Nat. Hist., p. 871 
(1846) ; Gray, Cat. Lep. B. M., p. 29, t. 3 (1852). 
Rare in the lowest valleys of Sikkim, but found in 
abundance by Méller’s collectors at Sivoke in May. The 
bands across the cell of hind wing in these specimens is 
almost obsolete, which distinguishes them readily from 
Tenasserim specimens, and the Assam form figured by 
Doubleday is also different in this respect. The second 
band on the fore wings is also shorter. I do not know 
how the form or species described as orestes, Fab., and 
which is quoted by Felder as occurring in Sikkim, differ S, 
and whether Nomius, Esp., of which orestes has been 
considered a synonym, ever occurs in the Sikkim Terai 
or not.* 
429. Papilio cloanthus. 
Papilio cloanthus, Westw., Arc. Ent., i., t. i. (1842) > 
Kollar, Hugel’s Kash., i., p. 405, t. 2 (1848). 
Moller gives the habitat of this species as from 
2—4000 ft., and its occurrence as from April till October, 
but I should consider it as rather a temperate than a 
tropical butterfly, having only seen it at about 6000 ft. 
Capt. Lang says in the N.W. Himalaya it occurs from 
5 to 7000 ft., and Doherty found it in Kumaon from 
2 to 7000 ft. I saw it in Khasia at 6000 ft., flying on 
sunny days round the tops of trees with very rapid 
flight, and hard to catch. 
430. Papilio sarpedon. 
Papilio sarpedon, Linn., Mus. Ulr., p. 196 (1764). 
Common in Sikkim at low elevations, and occurs up 
to 7000 ft. between April and October. A very strong 
flyer, and only caught when settled on wet places in 
the sun. 
= The female, which was hitherto saaderetient| is thus described by 
Moller :—‘‘ Expanse, 3°06 in. Like the niale, but with broader 
wings. The black band next to the basal band on the fore wing, 
which in the male goes right across to the hind margin, stops short 
in the female at the submedian nervure. The next band across 
the discoidal cell reaches only to the median nervure, whilst in the 
mile it goes a little beyond it.”
