In the Wadi el Aujah, , both sexes were seen resting on stones near the water's edge, while at the beginning of the following June, towards sunset, males were noticed in some numbers sluggishly resting on the precipitous, cliff-like walls of the Wadi el Kelt, a short distance above the spot at which the latter leaves the hills and enters the plain ; under such conditions the insects could generally be boxed or captured in tubes with little difficulty. The solitary occasion on which T. leleani was observed to attack man has already been Fig. 14. Tabanus leleani, Austen : a, head of <J in profile ; b, head of $ from in front, X 10 ; b, antenna of § from the side, greatly enlarged. Apart from its much paler (greyer) appearance, Tabanus leleani is distinguished ifrom T. cordiger, Mg., by the presence of a band on the eyes, by the row of erect Jiair on the upper margin of the occiput in the $ being much shorter, finer and less conspicuous, by the erect hair on the dorsum of the thorax being shorter and finer, and the covering of pale yellowish, silky hair more appressed. In general appearance and the majority of the external characters, except as regards size, which is usually distinctly larger, the species described above agrees with Tabanus albifacies, Lw., found in Egypt and
