10. DIPTERA. 



By Ernest E. Austen, F.Z.S. 



Eeceived November 13, read November 17, 1908. 



[Plate III.*] 



The Diptera brought home by the Ruwenzori Expedition were not numerous, 

 consisting of only eighteen specimens, belonging to six families and thirteen species. 

 Seeing that the Diptera of Central Africa have as yet scarcely been collected at all, it 

 is not surprising to find that a large proportion (no fewer than eight, or 61"5 per cent.) 

 of these species prove to be new. One of the new species was recently described 

 by Miss Gertrude Ricardo, but descriptions of the remaining seven will be found in 

 the following pages. 



In order to make the present contribution as complete as possible a few Diptera 

 obtained by Mr. G. F. Scott Elliot during a previous visit to Ruwenzori have 

 been studied in conjunction with those captured by the Ruwenzori Expedition. 

 Mr. Scott Elliot's material belongs to six species, five of which are apparently 

 new ; and, since three of the latter are additional to the species brought back by the 

 Ruwenzori Expedition, the total number of new species described below is ten. 



The Diptera procured by the Ruwenzori Expedition were collected by the Hon. 

 Gerald Legge and Mr. A. F. R. Wollaston.
