XII. — Notes on the Pangoninse of the Family Tabanidfe in

[Plate I.] 



The present paper embodies the results of an attempt to re- 

 arrange the s|)ecimens of Pangoninas in the British Museum 

 collection, dealing only, so far, with Pangonia^ Latreille, and 

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

 ledge of the Pangoninse since the publication of ' Dipteren- 

 Fauna Siidafrika's ' by Loew, nearly forty years ago, in which 

 he gave a valuable summary of the genera of the above, besides 

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

 years later, suggested a subdivision of Pangonia, Latreille, 

 which has been carried out in this paper. Schiner in 'Reise 

 der Novara ' (1866), 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 Pangoninse 

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

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

 Wulj)'s ' Cat. Diptera S. Asia ' (18i6). 1 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 

 species possessed by the British Museum^ including the descrip- 

 tion of eleven new species. 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 types, many of which are in such poor 

 preservation that it is difficult to form any opinion on them ; 

 when further modern specimens are available for comparison, 

 more of these types will very probably prove to be synony- 

 mous. 



The family Tabanidaiis divided into two divisions, viz. : — 



Hiud tibia with spurs. Ocelli usually present PANaoNiN^. 



Hind tibia without spurs. Ocelli absent Tabanin^. 



Pai^qoninm. 



The following table of genera of the Pangoninse of the 

 world compiled from different authors I have found useful to 

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

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

 follow later.
