A note to the effect that the fly brought home and 

 presented to the Societe de Geographie by Mr. Oswell 

 seemed to the author to be the same as that met with in 

 the Isle of Sennar (translated in " Ann. Mag. Nat. Hist.," 

 Ser. 2, X., p. 464). 



The following is a translation of M, Arnaud's note : 

 " From the examination that I was able to make of this 

 fly in the office of the Societe de Geographie, it seemed 

 to me to be identical with the one met with in the Isle 

 of Sennar, between 15° and 11° north latitude, where its 

 repeated punctures likewise kill animals, obliging shepherds, 

 especially those who keep cattle, to abandon the country 

 during the season at which it is most troublesome, that is 

 to say, in the months from January to May, in order to 

 take refuge on the banks of the Nile, where the fly is 

 only very rarely found. 



" I have myself been bitten by one of these flies, and 

 the sore that resulted lasted more than four months, with 

 insupportable itchings, which sometimes recur even to-day." 



[Whether the fly here referred to is a species of Tsetse 

 or not, it seems highly probable that it is identical with 

 the " Zimb " or " Tsaltsalya " of Bruce. The statement 

 that the Sennar fly avoids the banks of the Nile certainly 

 suggests the idea that it is not a Tsetse, though the same 

 objection might be urged against its being what is known 

 in the Sudan as a " Seroot " fly, i.e., one of the Tabanidae, 

 either a species of Tahanus near T. dorsivitta, Walk., or 

 else a Fangonia. In the paper by E. Marno, published in
