Pangonia, Latr. 

 Pangonia, Latr. lli>t. Nat. iii. p. 437 (1802). 



Rondani, in Archiv. Cancstr. iii. (1863), divides Pangonia, 

 Latr.. into Pannonia and Diatumineuni, making the first 

 posterior cell open or shut the distinctive character, and sub- 

 divides each again into a subgenus, with the eyes hairy or bare. 

 Loew in his ' L)ij)t.-Faun. JSiidafr.' used the divisions of the 

 posterior cells, and Ijigot has used Rondani's divisions since 

 for new species (see M(5m. Soc. Zool. Fr. v. 18S.>2). 1 have fol- 

 lowed this arrangement as it seems fairly satisfactory, though 

 the closing of the first jiosterior cell is a variable character- 

 istic in some species 1 have come across, viz. adrel. White, 

 M»S., concolor, \V i\\kvv, dej)ressa, Macq., noticed by the latter 

 in his description of depressa. The prolongations on the fore 

 tarsi of some male species are confined to those from Africa so 

 far as the species in the Museum are concerned — lonijirostris, 

 liardw., from Asia, being an exception, in the description of 

 this last is tiie only notice of tlie peculiarity which I have 

 seen. 



The following is a list of the described species of African 

 PaiKjouia^ Latr., divided into their subgenera as far as possible ; 

 but many of the descriptions are insufficient, where this is the 

 case they are left under Pan>ioiua, Latr. Those marked with 

 an asterisk (*) are in the Africa Museum Collection.
