Lepidoptera of Sikkim. 349 
A common species up to 5000 ft., but mostly found in 
tea-gardens, or places where the forest has been cleared. 
Occurs from March to December. 
148. Argynnis childreni. 
Argynnis childreni, Gray, Zool. Misc., i., p- 33 (1881); 
Lep. Nep., t. xi., # (1846); Butt. Ind., ii., p. 182. 
A. sakontala, Koll., Hugel’s Kash., p. 489, t. xii., d 2 
(1848). 
Moller notes the occurrence of this species at 8—4000ft., 
but I have only seen it rarely on Tonglo and the 
Singalelah Range in open flowery places in the forest, 
where it settles on flower-heads at 9—12,000 ft. It 
occurs from June to October. 
149. Argynnis lathonia. 
Papilio lathonia, Linn., Faun. Suec., p. 282 (1761) ; 
Butt. Ind., ii., p. 187. 
Argynnis issea, Gray, Lep. Nep., p. 11 (1846). 
Not a common insect in British Sikkim, where I have 
only taken it on the open parts of the Singalelah Range 
beyond Sundukpho in July, but it has been taken at 
Darjeeling in winter, and as low as 5000 ft. in February. 
Judging from the very numerous specimens brought by 
native collectors, it is very common in the interior. 
* 150. Argynnis gemmata. 
Argynnis gemmata, Butl., Ann. Nat. Hist. (1881), 
p. 32, t. iv.; Butt. Ind., ii., p. 188; Elwes, 
P. Z.8., 1882, p. 404, t. xxv., figs. 6,7, d 2. 
I saw this insect first on the high Chola Range in 
1870, and have since obtained it in quantity from 
natives who had been sent to Chumbi and Western 
Bhotan. It varies only in size, as far as I have seen, 
and the Sikkim form is the same as the two types 
in the British Museum, which probably came from 
northern Gurwhal. It has never been found on the 
outer ranges. 
151. Argynnis altissima. 
Argynnis altissima, Elwes, P.Z.8., 1882, p- 403, 
t. xxv., fig. 8; Butt. Ind., ii., p. 189.
