The new material received from the Imperial Bureau of Entomology through the kindness of the Director, Dr. G. A. K. Marshall, enables me to prepare this third paper on the Ethiopian fruit-flies. It is a proof of the great richness of the African Trypaneid fauna that of over 41 species received only 10 were referable to previously described species, and that no less than 8 new genera have been erected, most of them for very strikingly characterised forms.

The following undescribed species of Curculionidae were all forwarded to the Imperial Bureau of Entomology from the Division of Entomology, Pretoria, with the information that they were attacking various cultivated plants.

At the present moment our knowledge of the Dipterous fauna, including the Tabanidae, of Palestine is little better than complete ignorance, consisting as it does solely of a few isolated records of species—chiefly mosquitos. The following paper, which it is intended shall be succeeded by others dealing with other families of Diptera, based upon material collected by the author in Palestine during the recent campaign against the Turks, is a modest attempt to lift one small corner of the veil of obscurity.

From October 1918 to February 1919 inclusive I was stationed at Basrah, Lower Mesopotamia, and during that time I was able to devote some time to the collecting of Culicidae and their larvae.

Medical Officers and others interested in tropical sanitation often find great difficulty in rapidly identifying adult mosquitos. Four Anophelines have been found in the Zanzibar Protectorate, two of these being well-known malaria carriers. The identification of the two latter with the aid of a pocket lens is quite simple.

The danger of the introduction of yellow fever into Oriental countries has been the subject of much discussion since Sir Patrick Manson first drew attention to it in 1903. In 1911 Major (now Lt.-Col.) S. P. James, I.M.S., was deputed by the Government of India to study the conditions in the endemic areas of Central America, and in the principal sea-ports between that country and India. His report, published in 1913, was a most valuable contribution to our knowledge of the problems surrounding this subject. Among other recommendations, Major James suggested that further inquiry should be made with reference to the occurrence of Stegomyia fasciata in Far Eastern ports.
