According to Grunberg,t Stomoxys calcitrans occurs in Togoland, 

 but up to 1906 had not been received from Cameroon ; in German 

 East Africa, however, the species is apparently very common. 

 It may be added that S. korogwensis, Griinb.,{ which was described 

 from a male from German East Africa, is merely a synonym of 

 S. calcitrans, L., and that the difference in the abdominal markings 

 upon which Griinberg relies may be seen in many British specimens, 

 as well as in individuals from other parts of the world. It also 

 seems probable that S. sitiens, Rond. (described from a male from 

 Eritrsea) is a synonym of S. calcitrans, L. 



With reference to this species, as met with in Gambia and the 

 Congo Free State by the members of the Expeditions of the Liverpool 

 School of Tropical Medicine, Dr. J. L. Todd§ writes as follows : — 

 " This fly was caught in the open and in the houses of Europeans. 

 It feeds on all mammals, but seems to be especially fond of feeding 

 at the tips of dogs' ears. Both on the Gambia and on the Congo
