The present paper embodies the results of an attein])t to re- 

 arrange the specimens of Pangoninaj in the liritisli Museum 

 collection, dealing only, so far, with Panfjonia, Latreillc, and 

 its allied genera. Little seems to have been added to our know- 

 ledge of the Fangoninie since the |)ublieation of ' Dipteren- 

 P'auna Siidatrika's' hy Loew, nearly forty years .ago, in which 

 he gave a valuable summary of the gi'ncra of the above, besides 

 the description of species. Rondani, in Archiv. Canestr., three 

 years later, suggested a subdivision of Pangotiia, Latreille, 

 wliieh has been carried out in this |)aper. Schiner in ' Rcise 

 der Novara ' (1SG6), and other authors of a later date, have 

 established four or more new genera and described new 

 species. The only catalogues of any species of Pangonina 

 were those included in »Schiner's ' Cat. European Diptera ' 

 (1863), Osten Saeken's ' Cat. N. Amer. Diptera ' (1878), and 

 Wulp's ' Cat. Diptera 8. Asia ' (18i 6). I hope those I have 

 compiled will prove fairly complete, and be of some use in the 

 future study of the family, together with a few notes on the 

 epecies possessed by the British Museum, including the descrip- 

 tion of eleven new sjjecies. Any fresh specimens of Pango- 

 ninae, to be added to the National collection, would be most 

 acceptable and greatly facilitate further study, especially as 

 regards the "Walker ty]»es, many of which are in such j)00r 

 ])reservation that it is difhcult to form any opinion on them ; 

 when further modern specimens are available for comparison, 

 more of these types will very })robably [)rove to be synony- 

 mous. 



The family Tabanidaj is divided into two divisions, viz. : — 



Hiiul tibia with siau-a. Ocelli usually present Pangoxin^. 



Hind tibia without spurs. Ocelli absent Tab.\xinm;. 



Panqonin^. 



The following table of genera of the Pangonina3 of the 

 world com [tiled from different authors I have found useful to 

 work by, carrying it so far as to include Panyonia, Latr., and 

 the genera divided off from it ; Silvius and its allied genera to 

 follow later.
