down rocky-bedded streams iu Ilimalayau glens (3,0i)0 to 5,000 ft.). It pitches on 

 rocks iu luid-stream and flashes off again if approached. It is not common, and 

 very difficnlt to capture ; yet one very hot day in June I saw seven individuals 

 sitting with closed wings, motionless, on a fonl spot (by tlie damp sandy margin of 

 a stream), so close together, that I miglit have put my liat over nil of them. 

 E.Kcept on that occasion, I have only seen one at a time." 



Niceville remarks (see Moore, Lep. hnl. II. p. 257) about North- West Indian 

 athani'ts : " I took one specimen in October, 1878, at Kotgurth, imbibing moisture 

 on a damp s})ot near the Komilrsen stream. Of all the butterflies I am acquainted 

 with, this insect is the swiftest on the wing. I have taken a few small and 

 apparently hibernated specimens on hill tops near Simla in April, and have seen 

 the ordinary sized ones in various places near Simla in the autumn. My Darjeeling 

 specimens are decidedly darker than those taken at this end of the Himalayas. 

 E.Kpanse from 2'2 to 2-9 in." Mr. de Niceville was at the time when he wrote this 

 note (1879) most proliably not yet acquainted with the very pale Sikkimese 

 s])ring form. 



Hocking, P. Z. S. p. 238 (1882), considers onr insect " The wildest butterfly 

 that I know. Takes very long flights at a time, and returns to tlie same point. 

 Very shy." 



According to Elwes and Moller, I.e., the species is " common in Sikkim at low 

 elevations from April to December, and occurs up to 5,000 or 0,O0o ft." There are 

 several March examples in Moller's collection from Sikkim (now in the Tring 

 Museum) labelled 9. 3. 88 and 11.3. 87. 



Mr. Elwes adds : " I have seen his (Moore's) type of /nimasta, and have Oeylon 

 specimens {samafka). In neither is there anything at all to make them worthy of 

 distinction even as varieties." 



In Gazetteer of Sikkim, Mr. de Niceville says of nthamas : " The commonest 

 species of the genus occurring iu Sikkim, and found from A]iril to December from 

 OOOO ft. to the level of the Terai. The larva feeds on a sjiecies of plant very like a 

 prickly Mimosa." 



Mackiunon, Journ. Bombay N. 11} Hoc. XI. p. 377. n. 121 (1898): "Very 

 common in Mussoorie and in the Dun from April to September. The larva feeds 

 on the leaves of Albizzia julibrissin Durazz., Legumimsae, in Mussoorie, and on 

 Acacia catechu Wild., Lcguminosae, in the Dun."
