 mosquitos. Other biting Diptera include the Tabanids, Tabanus 

 rvhidvs, Wied., T. striatus, F., and Chrysops signifer, Wlk ; a 

 Psych odid, Phlebotomns nicnic, Banks, against which the finest 

 moscji ito net does not offer any protection ; the Muscids, Stomoxys 

 calcifrans, L. ; S. nigra, Macq. ; Li/perosia exigim, de Meij., which 

 remains upon the host when not feeding and lays its eggs in cattle 

 and carabao dung ; PMlaematomyia crassirostris, Stein, and P. inferior, 

 Stein, which are reported to attack cattle ; Simulium sp. ; a Chirono- 

 mid, Culicoides jvdicondvs, Bezzi, which is most abundant during the 

 times of heaviest rainfall. 



Fleas include : Ctenocephalus felis, Bch. ; C. canis. Curt. ; 

 XenopsyJla {Laemopsylla) cheopis, Roths, (plague flea) ; Pulex irritans, 

 L. (human flea). 



Other blood-suckers are a Reduviid, Triatoma {Conorhimis) rubro- 

 fasciata, DeG. ; Boophihis annulatus australis. Fuller (cattle tick) ; 

 Dernmcentor variabilis, Say (dog tick), which attacks dogs, cattle, 

 horses, rabbits and man ; and a mite, Trombidium sp., attacking man, 

 M'hich may be related to Trombidium {Leptns) akamushi, Brumpt, 

 which carries fever in Japan.

Several reports have been received of cattle attacked by Hypoderma 

 bovis (warble fly), which is apparently becoming more abundant and 

 more widely distributed in Ontario.

Although active operations were in progress as early as 1914 in 

 regions of East Africa known to be infected with trypanosomiasis in 

 man, it was not until March 1918 that any instance of this disease 

 was encountered, or at any rate recognised as such. Before the War 

 sleeping sickness was known to occur in certain parts of ex- German 

 East Africa and Glossina palpalis was prevalent. In 1910, a case of 

 trypanosomiasis occurred near the junction of the Rovuma and 

 Sassawara Rivers, and, upon search being made for tsetse-flies, 

 G. palpalis was not found, but it was finally established that 

 G. morsitans is the transmitter of sleeping sickness in that area. The 

 trypanosome shows characteristic differences from T. gambiense and is 

 identical with T. rhodesiense, 8 to 10% of individuals of G. morsituns 

 examined being infected with it. [The possibility of confusion with 

 T. brucei must be borne in mind.— Ed.] 



From the writings of German medical officers it would appear that 

 the known infected areas in ex-German East Africa are the southern 

 border of Lake Victoria Nyanza, the vicinity of Lake Tanganyika and 

 the neighbourhood of the Rovuma River from Sassawara to Liwale. 

 In Portuguese East Africa no mfected areas were recorded before the 

 War, but during military operations in that region the first case of
