On new African Species of the Genus (Jluysops. 507 



LXXIV. — Neiv African Species of the Genus Chrysops, 

 Meigen, in the British Museum {Natural History). By 

 Ernest E. Austen, 



The latest list of African representatives of this genus * 

 includes the names of eighteen species. As stated in the 

 "■ Notes " at the cud of the jjrcseu t paper, however, two of these 

 are synonyms. Six new species are described in the 

 following pages, bringing the number of known African 

 forms of these handsome and bloodthirsty flies up to twenty- 

 two. The Museum collection contains examples of at least 

 two additional species, of which descriptious will be published 

 in a subsequent paper. The types (or co- types) of all the 

 new species described below are in the British Museum 

 (Natural History).
