92 Mr. Cameron on 



supplemented by Mr. E. C. Cotes, lending me the material 

 in the Calcutta Museum ; by a large collection belonging 

 to the Bombay Natural Society, formed by Mr. R. C. 

 Wroughton, District Forest Officer at Poona; and by various 

 small collections, including a small, but very interesting one, 

 made by Mr. George Lewis, in Ceylon. 



In order to make this paper as useful as possible, more 

 particularly to Indian residents, I have given : — 



(i) A catalogue of all the known species, with their 

 localities, synonyms, habits, &c. 



(2) Descriptions of rare or imperfectly known species. 



(3) Descriptions of the new species. 



(4) A list of all the works and papers relating to the 

 Oriental Hymenoptera, and 



(5) Observations on their geographical relations. 



Mr. Rothney's collecting was chiefly in the Calcutta 

 district, namely, in the neighbourhood of the City ; in 

 Barrackpore, Sittaghui, Samnugga, Ishapue, Serampue, 

 Chandauague, Gusery ; at Port Cauumy to the south, 

 Burdwan to the north ; Nischindepue to the north-east. 

 Also in Tirhoot, Bengal ; Mussourie, North-west Province 

 (in September and October), in Allahabad, North-west 

 Province ; and a few species from Dargeeling, Madras, 

 Bombay, and Ceylon. 



Mr. Wroughton's collecting is principally from Poona 

 (Dekhan) and Bombay.
