IMPCRTHJ SPECIMENS: Records in the literature for HHPT (Guerl'n.FEnev1'IIe I@¢l843), one of the type localities of synonymous Ixodes elegans) should be discounted. Although A. varie a. tum frequently arrives at the Cairo abattoir on cattle from e Sash and from other areas of East Africa the species has never become established here (Hoogstraal 1952A). Pbctremely few females are found by the time cattle reach Cairo.

A. varie atum has become established and is a serious problem in the (St. Kitts, Guadeloupe, Antigua). As early as 1895, Barber wrote an account, both pleasant and critical, of the ravages of "the gold tick“, A. varie atum = H alomma venustum) in Anti a. See also: Nemfim~), Ticks in the West Indies I-I914), Ford (1919), Saunders (l9l4A,B,l915,l919), Senevet (1938), and Mauze and Mbntigny (1954). It appears that A. varie.

atum has been found in GUATEMALA (Neumann 1899,1911), bEt'£EE¥3

ave been no subsequent reports of its presence there. There has been some question about West Indies records among American workers who have not visited these islands. Numerous specimens from West Indies may be seen in British Museum (Natural History) collections.

Three males are stated to have been found on a dog in southwestern FRANCE (Lamontellerie 1954).

MISCEILANEOUS: The distributional map of Tendeiro (1947) which Inclaes Egypt and Sinai and omits the Sudan and parts of Ethiopia, Eritrea, a.nd the Somalilands, should be modified.

TUNIS has been listed as a collecting locality based on specimens labelled from a hedgehog on Djerba Island collected by A. weiss (Galli-Valerio 19111). Colas-Belcour and Rageau (1951), with ample reason, consider this record doubtful. It may be based on misidentification of an immature Hyalomma sp.


Where it occurs, A. varie atum is often the most common tick on cattle. Its incidence on oéher domestic animals varies locally

but is usually less than on cattle. Among wild animals, the buf. falo and numerous kinds of antelopes are important hosts. Other

wild animals are either rather seldom infested by adults or those
that more frequently harbor them, such as the rhinoceros, general-
ly are not mzmerous in nature. Carnivores are only exceptionally
attacked. Man is rarely utilized as a host by adults, though
nymphs attach more frequently and larvae are sometimes serious
pests. Our knowledge of the host preference of immature stages
is fragmentary. Nymphs feed on moderate size to large animals
including all domestic animals and larvae attack mostly birds

"Though pinpoint blemishes in the tanned skins of goats are attributed by the (Nigerian) trader to the bites of ticks, this animal has been found to remain uncommonly free of ticks, particularly in the dry season. In the rains, when all domestic animals become grossly infested if not hand dressed, the goat is usually only

parasitized by ....... A. varie atum and then to any extent only in the hollow of the heels, the clefts of the hoof, and in the

perineum. These exceedingly tenacious parasites set up a local inflammation with pus formation due to infection of the wound by organisms of necrosis, particularly in the feet. Severe lameness may be caused, and virus diseases, e.g., heartwater may be transmitted. (Beaton 1939).
