remains quiescent for 28 days between terminating feeding and com- 

 mencing oviposition. Eggs hatch after 36 daysj larvae and nymphs 

 each feed for eight days. Twenty-foixr days after feeding, nymphs 

 molt to adTilts. (See also Tselishcheva 1953). 



The ecology and distribution of H. turanicum (s H. glabrum ) 

 in southern Africa are described by fEeiler (195fc>). It is present 

 only in the Karroo areas of the eastern Cape, western and south- 

 western Cape, the Cape midlands, and the Brokenveld of southern 

 Orange Free State, but absent elsewhere in the Union and in Basu- 

 toland, Namaqualand, Bvishmanland , Bechuanaland, and Southwest 

 Africa. Although this tick exists in areas with as little as 

 0.5 inches of annual rainfall, it is more common where five to 

 ten inches of rain falls annually. It is absent in areas with 

 over fifteen inches of anntial rainfall, in winter rainfall areas, 

 and, with a single exception, where rain is distributed throughout 

 the year. South African cold and heat do not appear to restrict 

 the range of H. turanicum inasmuch as it is found in areas with 

 up to 150 days of frost per year. This is the only Hyalomma in 

 localities where snow occurs in South Africa. Karroo type vegeta- 

 tion areas including those mixed with Mesembrianthemum , sourveld 

 grass, and, to a lesser extent, sweetveld grass support H. turanL - 

 cum . It is absent in all forests, parklands, greisslands^ and other 

 desert thorn, succulent, and grass areas. Adults are active during 

 the summer and in some localities during the entire year. 



Peirvomaisky (19^^.9) tmsuccessfully attempted the rearing of 

 a full Fi generation from parthenogenetic females of H. turanicum . 



Neitz (1954) was tinable to achieve transmission of the virtis 

 of sweating sickness of cattle in South Africa by means of H. 

 turanicum (= H. rufipes glabrum ) ♦ As already noted, Delpy Tl952) 

 indicated tha^ this tick is "not of considerable importance* in 

 transmission of bovine theileriasis, Theileria annulata , in Iran. 



The vertical rings of the leg segments of both sexes of H. 

 tiiranicum are usually not so contrasty as they are in H. rufipes 

 but the middle segments of the two pairs of hind legs "show a 

 dorsal enamelling not found in H. rufipes ; this is especially 

 distinct in dry specimens. The^circumspiracular area of neither
