The following report is based on a tour which extended from September 1915 to February 1917, but included in it are also some observations made during a few months residence in 1914.

The area comprised lies partly in the Northern Territories of the Gold Coast, and partly in Togoland (see Map, Bull. Ent. Res., V, p. 32). It extends from 8° N. to 9° 45' N. and from 0° 15' E. to 2° 30' W. My headquarters were at Yapi on the River Volta about 28 miles south-west of Tamale, the capital of the Northern Territories. I have already described in a previous report the nature of the country and the type of vegetation, so need not repeat them here. I examined the whole of the Volta from Yapi to Yeji by canoe, and then followed a sinuous route on my return journey, keeping as close to the River as possible. The country between Yapi and Daboya, a large town with an important ferry on the Volta, was traversed on several occasions. From Daboya I went to Bole and made my temporary headquarters at Larabanga, the centre of the game and Glossina submorsitans area. Here I spent several weeks under canvas in three separate localities in the bush. On my homeward journey I visited Yendi, formerly an important German post in Togoland, thence going to Salaga and Kete-Krachi, where I crossed the Volta and proceeded to join the main north road at Atabubu (Tabobo).

While the Oriental and Neotropical Trypaneids have been the subject in recent times of extensive studies, those of the Ethiopian Region are still almost in the same condition in which they were left by H. Loew in his valuable paper of 1861. Only more recently Prof. Hendel has made an attempt to erect some Ethiopian genera in his general classification of the family; but all these genera are only shortly characterised by means of dichotomic tables, and most of their type-species have been given names as new species, but without any description.

The present research was carried out in the Department of Agricultural Entomology at Manchester University, under the direction of Dr. A. D. Imms. I am greatly indebted to him both for giving me the insects upon which this research was prosecuted, and also for much help at the University, and afterwards in looking over my paper and aiding its publication.

The Imperial Bureau of Entomology has recently received from Mr. A. H. Ritchie, Government Entomologist in Jamaica, specimens of a weevil which he found to be doing serious injury to the tubers of a crop of sweet potatoes. The insect belongs to the sub-family Cryptorrhynchinae and proves to be an undescribed species of the genus Palaeopus, Fst. (Stett. Ent. Zeit., 1896, p. 51 & 60).

The following are some new species of Aphididae found in Africa. The majority are from the collection sent me by Mr. F. C. Willcocks, Entomologist to the Sultanic Agricultural Society of Egypt. Others have been received by the Imperial Bureau of Entomology.

Four previously described species are added, so as to keep these lists complete:—

1. Macrosiphum dahliafolii, nov. sp.

2. Aphis durantae, sp. nov.

3. Aphis zizyphi, sp. nov.

4. Aphis ficus, sp. nov.

5. Aphis tamaricis, sp. nov.

The specimens here dealt with were collected by Mr. A. H. Ritchie, Government Entomologist for Jamaica, and were handed to me for determination by Dr. Guy A. K. Marshall, Director of the Imperial Bureau of Entomology.

The control of flies is a serious problem in the Egyptian Campaign. In desert camps flies develop at an extraordinary rate, unless rigid sanitary precautions are taken. In native villages they seem to be taken as a matter of course, and it is a common sight to see fruit and food of all kinds, in shops and on street-vendors' carts, swarming with flies. Small children suffering from conjunctivitis are seen in the streets with their eyes thickly covered with flies. Flies of the house-fly type (Musca) are the most troublesome, although blue-bottles (Calliphora), green-bottles (Lucilia) and Sarcophaga are found. These latter are often met with in the desert in the small clumps of palm trees known as “ hods.”
