the British Museum, and others from the Hungarian Museum at 

 Budapest. To these collections I have added the species received from 

 the Albany Museum, Grahamstowu, and those sent me by Dr. Brauns 

 of Willowinore (Cape). This large amount of material enables me to 

 give here a general review of the group, and to describe many new 

 genera and species. 



The collection contains a number of species determined by Bigot, 

 who had prepared a paper on the Diptera sent him from the Cape by 

 Dr. Peringuey.* Most of these species have never been published; but 

 many of them were evidently classified from Mac-quart's types in 

 Bigot's collection. For instance there is a type of Lasioprosopa biyoti, 

 Macquart, 1855, described from Oceania, which is none other than 

 Corsomyra olyripes, as already stated by Schiner, who had received 

 the species from Macquart himself ; this important synonymy has not 

 been as yet recorded in the catalogues. 



The Bombyliid Fauna of South Africa, as compared with that of 

 the remainder of the Ethiopian region, shows some peculiar characters, 

 which make it at once recognisable. 



Firstly thei'e is a large number of purely endemic genera, such as 

 Adelidea, Crocidium, Nomalonia, Peringueyimyia, and some new ones 

 Sosiomyia, Oniromyia, Pseudempis and Ptcr"laj-. But the main 

 characteristic is the presence of the genera Corsomyra and Callyn- 

 Ihrophora, which, with their now known 10 species, are exclusively 

 South African ; they represent certainly an endemic line of develop- 

 ment which is no doubt adapted to some special characters of endemic 

 flowers, to which they are adapted for pollination, as shown by their 

 extraordinary facial brush. Very characteristic among the important 

 genera is the great number of the species of Bombylius a genus which 

 is most sparingly represented in Central Africa ; eminently peculiar 

 are some groups of species, like that of the allies of Bombylius 

 micans, and that of B. lateralis and bivittatus. The related genera 

 Systoech/is, Anastoech/is and Dischistus comprise also characteristic 

 species, chiefly those of the two first-named genera, which are very 

 close to those of the group of Bombylius micans. Lomatia has a good 

 series of peculiar forms, very often remarkable for their great size. 

 In the genera Anthrax and Spongostylum peculiar specific forms are 

 scarce, and so are likewise those included in the genera TJiyridanthrax, 

 Villa and Litorrhynchus. Against this a great number of characteristic- 

 species is to be found in Exoprosopa, some subgeuera of which, like 

 Metapenta and Acrodisca, and also groups, like those of heros, 

 senici'lus, capensis, etc., are exclusively or pre-eminently South
