HOSTS 



R. kochi is known chiefly from domestic cattle. Duikers 

 and oTher forest antelopes may be presumed to have been its 

 original hosts. Animals on which immature stages feed are un- 

 known. 



Domestic animals ; Cattle: Donitz (1905,1907). Lewis (1934) > 

 Schoenaers ^1951A,B^. Rousselot (1953). Theiler *s records are 

 from cattle. Donitz 's material from Soadani and Lindi was prob- 

 ably taken from introduced cattle. Dogs (Lewis 1931B). 



*Wild animals ; Lion and spurfowl (Lewis 1934). Buffalo 

 (Theiler, unpublished). 



BIOLOGY 



Life Cycle 



Eggs hatch in 2A days and larvae feed for five or six days 

 according to Rousselot (1953B). No other details are known. 



Ecology 



Schoenaers (1951A,B) found R. kochi only above 2000 meters 

 elevation in Ruanda-Urundi and specimens sent to Rousselot (1953B) 

 were from altitudes between 2400 and 2500 meters elevations. Van 

 Vaerenbergh (1954) also reported the same altitudinal range, and 

 Theiler and Robinson's (1954) Congo localities are at similar 

 elevations. As already noted, Sudan specimens have been taken 



*Lewis (1934, p. 41, footnote), states that these specimens may be 

 R. capensis .
