802 REPORT OF THE HARVARD AFRICAN EXPEDITION 
Betcran Conco.— Near Irumu, many males and females, off cattle, 
May 27, 1927 (R. P. Strong). Luvungi, abundant on cattle, January 30, 1927. 
Uvira, in grass. 
This species is the common cattle tick throughout tropical and South 
Africa, Madagascar, Mauritius and Réunion. It has been introduced into the 
West Indies and Central America. It is quite common in the Belgian Congo 
(J. Schwetz, 1927, Rev. Zool. Afric., XV, 1, p. 91). The known hosts include 
many wild and domestic animals. G. A. H. Bedford (1920, Jl. Dept. Agric. 
Union South Africa, July, p. 20 of reprint) states that he found by experiments 
that this tick can transmit heartwater of goats, a disease probably caused by 
Rickettsia ruminantium Cowdry.
