Found by Dr. Balfour at Senga and at Roseiros, on the Blue Nile. I ha\e not 

 seen any specimens myself from Egypt or the Sudan, but I ha\'e had si)ecimens 

 fi-om Uganda. It also occurs in Khartoum. Tliis is a malaria carrier.

Dr. Balfour obtained many on the Pibor (Bor and South of Goz-abu-Gvuna, 

 White Nile) which showed no special peculiarities. He says they are very connnon 

 there, but not very vicious. This species is much subject to the parasitic tick, 

 often being covered with them. It is also probably a malaria bearer. 



Previously, Captain Lylc Cummins obtained specimens from Bahr-El-Gliazal. 



Genus Cellia, Theoliald

Found by Dr. Pialfovn- at Baro, also at Roseires on the Blue Nile 

 (W. L. S. Loat and Di'. Balfom-) ; Cairo (Keatinge) ; Ismailia (Ross). 



This seems to be an abundant North and Central African species, and is 

 undoubtedly a malai'ia bearer. It also extends into Arabia, having recently been 

 sent me from the Aden hinterland, and it also occui-s in Palestine.
