males axe also not infrequently found on traders' camels reaching 

 the environs of Cairo from the Sudan, 



This species has been taken from imported cattle at East 

 London, South Africa (Robinson 1926), but is definitely not es- 

 tablished in the UNION OF SOUTH AFRICA (Theiler, correspondence). 

 PAIESTINE records (Bodenheimer 1937) probably also represent 

 imported specimens. 



HOSTS 



A. lepidum is chiefly a cattle parasite with smaller domes- 

 tic ammals and a scattering of wild herbivores as second choice. 

 Large ground birds and carnivores are rarely attacked, A single 

 adxilt has been teiken feeding on man. Nymphs have been found on 

 antelopes, bustards, and domestic cattle and dogs. The host pre- 

 dilection of immature stages is still poorly known. 



Domestic animals ; All investigators listed above refer to 

 cattle as hosts of this tick. Siodan records are almost the only 

 ones available for other domestic animals. These include camels, 

 horses, mules, goats, sheep, and dogs. Individual camels on oc- 

 casion are heavily infested. Although camels appear to be rather 

 important hosts in central Sudan, local camels in the north are 

 not known to harbor this tick, Evans (1935) listed sheep and 

 dogs as hosts in Tanganyika, 



Wild animals ; Buffalo (Robinson 1926, King 1926, Wilson 

 1950C, various Sudan records above). Rhinoceros (Wilson 1950C). 

 Grant's gazelle and hartebeest (Wilson 1950C, Sudan records 

 above). Roan antelope eland, giraffe, tiang, wildcat, and great- 

 er bustard (various Sudan records above). Burchell's zebra and 

 spotted hyena (Theiler, unpublished records). Cheetah (Robinson 

 1926), Ostrich (id and 1$ in Hoogstraal collection, from "\iest 

 of Afmadu", Somalia, 1952, Col. D, Davis legit ). Of 1,9 Thom- 

 son's gazelles examined in Tanganyika, only two yielded exghz 

 males and one female A, lepidum ; none were found on numeroiis 

 other game animals examined there (J. B. Walker, unpublished),
