mosquito and Chironomid larvae were easily obtained from water in 

 old tins and other receptacles in both the European and native com- 

 pounds. A species of Taeniorhynchus was common in the houses and 

 MansonioUes sp., though rare, was also found in houses. Generally, 

 the larvae of different species are not found in the same receptacle 

 in any great variety, one genus or even species usually predominating. 

 One receptacle, on one day, yielded only Cnlex ? duttoni, Theo., and 

 a week later almost exclusively S.fasciata. Of thousands of mosquitos 

 bred, few were Anophelines, 90 per cent, consisting of Culex or 

 Stegoniyia. The following species are recorded •.—Toxorhynchites 

 brevipalpis, Theo., Eretmapodites chrysogaster, Graham, Anopheles 

 {Myzotnyia) costalis, Lw., Cidex tigripes, Gr., var. fuscus, Theo. ; 50 

 per cent, of the mosquitos were species of Culex, including C. duttom, 

 Theo., C. univittatus, Theo. and C. invidiosus, Theo. ; the true 

 C. pipiens, L., was not represented ; Taeniorhynchus cristatus, Theo., 

 occurred ; and a few Mansonioides uniformis, Theo., and possibly 

 some M. africanus, Theo., were captured in houses. Stegomyia 

 Jasciata, F., was very common in and around houses, chiefly towards 

 the evening. Stegomyia, ajricana, Theo., S. apicoargentea, Theo., 

 S. simpsoni, Theo., and S. poweri, Theo., were bred, and specimens of 

 Culiciomyia nebulosa, Theo. and Ochlerotatus {Protomacleaya) alhoven- 

 tralis, Theo., also occurred in the collection.

With one exception, the new Tabanidae described, were obtained 

 from the Transvaal or from the West Coast of Africa. Those from 

 the Transvaal, were all taken in the vicinity of Onderstepoort, near 

 Pretoria, and formed part of a collection which also included the 

 following species : — Tabanus sericeiventris, Lw., T. insignis, Lw., 

 T. taeniola, P. de B., T. ditaeniatus, Macq., T. atrimanus, Lw., Haema- 

 ■topoia scutellaris, Lw.,(?), Chrysops stigmaticalis, Lw., and Diatomineura 

 ■aethio'pica, Thun. 



Tabanus triquetrornatus, sp. n.. Calabar, Southern Nigeria ; 

 T. fuscipes, Ric, var. oculipilus, var. n., Transvaal ; Haematopota 

 transvaalensis, sp. n., Transvaal ; H. theobaldi, sp. n., Transvaal ; 

 H. pinguicornis, sp. n.. Gold Coast ; H. angustifrons, sp. n., Belgian 

 €ongo ; H. exiguicornuta, sp. n., Lokoja, N. Nigeria ; H. corsoni, 

 sp. n., Gold Coast, are described.

 topota from British West Africa, is given.

Though biting and bloodsucking flies are common among the 



MusciDAE, the larvae are, as a rule, incapable of biting or sucking 



blood. The Calhphorinae however present some curious exceptions, 



in which the conditions are reversed, in that the larvae can bite and
