the Indian Museum, in his endeavour to get the extensive 

 collection of these insects possessed by that Institution arranged 

 and determined. The whole of my own work in oriental 

 species, and the enlistment of the valuable services of Prof. 

 Kieffer in Chironomidce , . Mr. Theobald in Culicidce, Miss 

 Ricardo in Tabanidce, Herr Lichtwardt in Dolichopidce and 

 Prof. Bezzi in Trypetidce, have had that origin. In the above 

 groups, about 200 species will figure as new, whilst the publi- 

 cation of the remaining papers I have in hand will raise the 

 total of new species described by me to about 300. 



The great majority of the types of these 500 new species 

 are preserved in the Indian Museum collection.
