XXXII. — New African PIdebutomic Diptera in the British 

 Museum {Natural History). — Part I. Tabanidce. By 

 Ernest E. Austen. 



The interest excited at the present time by blood-sucking 

 flies, in view of the possibility that they may act as carriers 

 of micro-organisms pathogenic to man or domestic animals, 

 supported by an appeal for specimens circulated by II. M. 

 Foreign and Colonial Offices throughout the British Empire, 

 has resulted during the last year or two in the acquisition 

 by the British Museum (Natural History) of a certain 

 amount of material, chiefly from Africa, including many 

 new species. Some of the latter, from Tro[)ieal Africa, are 

 described in the following pages, and descriptions of others, 

 including a number of additional species of Hceniatopota (a 

 genus of which the African continent is apparently the 

 lieadquartcrs), will be published shortly in subsequent 

 communications in this scries. The types of all the new 

 species described below are in the British Museum (Natural 

 History). Coloured figures of the majority will appear later 

 in an official publication.
