O. Wallichii.—-hocdX, I only having seen it in the rich dark forests 

 about Kotgurh and Narkunda, fifty miles from Simla. 



Colias JEdusa. — Abundant in the Himalaya ; may be caught also in 

 the winter in Oudh and at Umballa. 



C. Hyale. — Tolerably abundant in the Himalaya, 5,000 to 10,000 ft. 



C Neriene. — Ditto. 



Terias Hecdbe. — Has a wide range : plains of India and Himalaya, 



T. Sari. — Same habitat as last. Larva reared on Mimosa (sp. ?) 



T. Ziceta. — Never seen at Oudh, but at Umballa it seems to occur 

 nearly all the year round. Obtained it also at Kussowlie, in the 

 Himalaya. It has a very weak flight, amongst low herbage, on the 

 skirts of woods and gardens. 



Eujilcea Core. — Abundant in Oudh and at Umballa. ■ Seen also, 

 but not common, in the Himalaya. Larva reared on Nerium odorum. 



E. Midamus. — Obtained only two specimens, one at Seetapore, in 



Oudh, the other in a valley in the Himalaya. It seems rare in these 



regions.

The following day was unmarked by any occurrence worthy of 

 note ; tlie general aspect of the river was unchanged ; but on the third 

 day as the sun rose, and the mist, which, during the night, had overhung 

 the river, cleared away, the floating islands appeared in sight ; at fixst

 the richest verdure and reeking with dew, floated slowly past, never, 

 however, destined to reach the sea, but to be carried back by the re- 

 turning tide. They were said, by my negro, to be infested with snakes, 

 on which account he was very anxious to give them a wide berth. 

 Near this spot I was much struck with the appearance of a day-flying 

 moth, of vivid green colour, the hind wings shading ofi" into a pure

 sionally, also, over the adjacent bushes, but of which, unfortunately, 

 owing to the swiftness of its flight, I failed to secure a single specimen. 



Shortly afterwards we reached the sand-hills, which, rising up from 

 the river's edge, are covered with a short and stunted undergrowth, with 

 here and there a clump of bushes and forest trees, and to this spot I
