In the Red Sea Provdiioe there is a greater variety of species. S. fasciata was common 
at Port Sudan and Suakin until measures were taken by the Sanitary Autliorities to 
suppress - them. ('. fatiijaus is again the well-breeding mosquito, and also occurs in 
company with /’. cuMidis in pools in khors during the dry season. A single specimen of the 
brilliant black and white Scutomijin siujens was taken in February, 1908, on the track 
leading over the hills between Suakin and Erkowit ; while the larv® of Thcdhnhlin. 
sjiii'thipdlpts was found abounding in streams in the vicinity of the latter place. This 
mosquito appears to be a strict vegetarian in that locality, for everyone living at Erkowit 
at the time when there were numbers of them to be found declared that there were no 
mosquitoes save adjoining the stream by the Mudir’s Garden, in which a few C. Jatiuans 
were breeding. 
A new salt-water breeding mosquito, ('ulex salas, has lieen found at Port Sudan by 
Dr. Crispin, who has taken considerable trouble to obtain ijerfect specimens. This species 
appears to be very particular as to its breeding places, as so far its larviC have only been 
seen in a tub sunk in a certain pit containing salt water, notwithstanding the fact that 
other similar tubs, also containing salt water, were available in the immediate vicinity. 
Dr. Crispin once noticed mosquito larv® in a salt-water pool on the foreshore, but their 
species was not ascertained. 
The mosquitoes of Khartoum are dealt with by Dr. Balfour in his Report “ Sanitary 
Notes,” but to those mentioned by him, two species, probably brought down by boats, must 
be added. In August, 190G, a perfect specimen of Mitridns smlanensis was taken in the 
Sudan Club ; and in September of the following year a battered and worn female 
< 'hry.'i(iconopi< aiirites was oap)tured in the Laboratory Garden, while in an adjoining 
collection of water were some young larvae, suspected of being the progeny of this 
female. These larvae were unfortunately destroyed before they could be identified. 
Among the various species from the White Nile are (Julex hirsuiipulpis — ijreviously only 
recorded from El Obeid — .Edeomyki sqnammipentia and Mimeteculex kinyii, all taken at 
Taufikia. The latter is common in the swamps in that locality, but is not so frequently 
seen on boats on the river. Two specimens of M. sud(in,e)i,sis were bred out from pupae 
taken from a pool adjoining a native village near Taufikia, and a single specimen was 
caught by Mr. Goodson at Kodok. 
The beautiful 'Tienioi'/iyuchuH violaceus also occurs at Taufikia and Kodok. 
Muii.oii>yi<i, ciroiDiitentacea, UnDiokoiin. pdlliducepluihi and its sub-species, ct/’ruleiis, were 
all taken on board a steamer on the Upper \Vhite Nile. 
linnksiella liiffiolnterdlis is very plentiful in woods and swamps around Nasser on the 
Sobat, and is a vicious daylight biter. single specimen of Steyamyia anjenteopunctata. 
also came from this locality.

During certain seasons of the year, vast swarms of the little sandfly Siiiiidium 
(jriseicullis — locally known as Xiniifti — occur in the northern parts of Dongola Province.
