whenever I observed it round domestic animals the poor creatures 

 were in many places quite red owing to the hlood that streamed from 

 the wounds caused by the flies. Nevertheless this Pangonia 

 appears to prefer to suck the nectar of flowers rather than l)lood, since 

 I frequently found it on the blossoms of dilTerent species of 

 Pelargonium : other kinds of Pangonia, on the contrary, I never 

 met with on plants."

This handsome species has not hitherto been met with outside 

 Somaliland, where however it would appear to be locally common 

 and a plague to animals. In 1894 Captain (now Colonel) 

 H. G. C. Swayne, R.E., when passing through Ogaden to the Webi 

 Shebeli, was much pestered by this fly and an unidentified species 

 of Pangonia, which swarmed on his camels and constantly drew 

 blood.* According to Colonel Swayne, P. beckeri and the unkno^^^l 

 species are called "Doog" by the Somalis,t who wiU not allow their 

 live-stock to graze in places frequented by these flies and Tabanus 

 morsitans, Ricardo, a small but extremely bloodthirsty species, 

 known to the natives as " Balaad." 



The ten specimens of Pangonia beckeri in the Museum Collection 

 include : — One female (the type of P. tricolor, Austen, nee Walker) 

 from Bun FeroU, north of the Webi ShebeU, West Somaliland, 

 June, 1895, "biting man and animals" (C V. A. Peel); eight 

 females from Bohodle, British Somaliland, 1903 {Veterinary- Major 

 Appleton, A.V.D.) ; and one female from Cuban, British Somaliland,
