VII. NEW ORIENTAL N E M O C E R A . 



By E. Brt'xetti. 



In the present paper are described nearly lift}'' new species 

 belonging to the first suborder of Diptera. Figures of some of 

 them, especiall}' wings of the somewhat closely allied species of 

 Rhyphus and Dixa, will appear in my forthcoming volume on 

 Nemocera (exclusive of Culicidae and Chironomidae) for the 

 ''Fauna of British India " series.
