﻿118 EENEST E. AUSTEN — NEW AFKICAN 



p. 56 (1908)) has pointed out that the two names apparently refer to the same 

 species, and that if this be so P. chrysopila, Macq., is a synonym of P. nobilis, 

 Wied. ; without making a comparison of the types the matter cannot, however, be 

 decided definitely. Of P. nobilis, the type (from the Cape of Good Hope) is 

 in the Berlin Museum ; the type of P. chrysopila, the provenance of which is 

 given by Macquart simply as " Afrique," is in all probability lost. It is stated 

 by Macquart to have originally been in M. Serville's collection, which, according 

 to Osten Sacken (Cat. Dipt. N. America, p. xvi (1878)), eventually passed into 

 the possession of the late M. Bigot. As most Dipterists are aware, Bigot's 

 collection on the death of its owner was acquired by the late Mr. G. H. Verrall, 

 by whom it was bequeathed in 1911 to his nephew, Mr. J. E. Collin. In reply 

 to enquiries, Mr. Collin has been good enough to inform the writer that the type 

 of Pangonia chrysopila, Macq., is not in the Bigot collection, and that he cannot 

 find the name in the catalogue of the collection made when it passed into Mr. 

 Verrall's hands. 



A female Cadicera from Barberton, Transvaal (Dr. P. Rendall) recently 

 acquired by the British Museum (Natural History) apparently belongs to the 

 species under consideration.
