ill May only oiie or two could be found. Hippohosca liirsnta, 

 Aust., was taken repeatedly on waterbnck and on puku. Two 

 other species, one wingless, were also collected at Nawalia and 

 Lave still to be identified. 



In appendix " A," A. F. Wallace and L. Lloyd describe experi- 

 ments on the possible transmission of trypanosomes by Taha/ivs. 

 Although 128 flies were used, the results were negative. 



In appendix " B," A. F. Wallace describes an attempt to 

 transmit T. rhodc.sicnse by means of Oi'nitJi()doiu.s iiiouhuta; 125 

 ticks were used and 5 sets of experiments made. The results were 

 negative.

This paper contains a very full account of these files and their 

 larvae. Up to the present only 4 species are known, and these 

 are exceedingly closely related to one another : — Anclimeromyia 

 hiteola, A. (Clioeromyia) praegrandis, C. choerophaga and 

 C. houeti. The genus is confined to tropical and sub-tropical 

 Africa. A. Ivteola has the widest geographical distribution, and 

 is found from Senegal to the Sudan and down to the Cape. The 

 author points out that its distribution coincides practically with 

 that of the Negro and Bantu races, and that the fly is not found in 

 the sub-tropical regions of the north inhabited by the Arabs and 

 Berbers. A. praegrandis (Cordylobia jjraegrandis, Aust.) is known 

 in Natal, Cape Colony, the north-west of Rhodesia and Nyasaland, 

 and has been been met with by the author in French West Africa 

 on the Upper Gambia, and by Bouet on the Upper Ivory Coast. 

 The remaining species, C . houeti and C . choerophaga, are up to 

 the present onlj' known from the Western Sudan and the Niger 

 Valley. The former species, which is certainly the least widely 

 distributed, has only been found twice in the neighbourhood of 

 Timbuktu and Niamey. The latter has been frequently met with, 

 and though generally alone, sometimes in company with the 

 former species, throughout the whole region of Timbuktu, Goa, 

 Mopti and Djenna. 



A. luteola is found in shady places about human dwellings, and 

 appears to have a preference for the neighbourhood of latrines. 

 The fly was observed to feed principally upon fallen fruit and 

 dejecta generally early in the morning in cool weather or about 

 sunset. Dr. Roubaud considers that flie insect is constantly asso- 

 ciated with man and lives more or less exclusively in his 

 dwellings. 



The aduHs of Clioeromyia, on the other hand, are not dependent 

 upon man, but live in the interior of the burrows of the wart-hog
