Fork-cells of equal length anlennat us. 



Anopheles (Cellid) pharoensis, Theobald. Palpi brown with two 

 narrow white bands, and white tip, elsewhere mottled with white. 

 Thorax brown, with a dark median line and a fawn coloured stripe on 

 each side ; abdomen brown, densely covered with yellowish hairs and 

 scales, and with lateral tufts of darker scales. Legs with femora and 

 tibiae banded and mottled, metatarsi and tarsi with broad apical white 

 bands ; last tarsal joint white. Costa with three dark spots, the middle 

 one the largest, the two others small. A distinct and very widely dis- 

 tributed African species. Recorded from Palestine, Egypt, Soudan, 

 Gambia, North and South Nigeria, Togo Land, the Belgian Cogo, An- 

 gola, Southern Rhodesia, Delogoa Bay, and Madagascar. 



Anopheles (Cellia) cinctus, Newstead and Carter. Distinguished 

 from the above and allied forms by the rings on the metatarsi of the 

 middle and hind legs ; only one specimen is known, from Ashanti. 



Anopheles (Cellia) jacobi, Hill and Haddon. A large black and white 

 species with spotted legs. Palpi black, with an incomplete white band 

 near the base, a narrow band about the middle, and an irregular white 

 band at apex. Thorax sepia with three white longitudinal bands, as well 

 as three on pleura. Abdomen thickly covered with yellow scales and 

 hairs, and with lateral tufts of black scales on second to seventh seg- 

 ments. Legs dark grey, spotted with white ; metatarsi and all tarsi 

 except the third of the fore and mid legs with white bands ; the last 

 tarsi of all legs white. Costa with three small white spots, a fourth at 

 the apex, and two small spots at the base. The larva, which lives in 

 springs, is large and deeply pigmented ; antenna without a branched hair 

 on the shaft, but with a small spine on the external aspect. Frontal 

 hairs branched ; palmate hairs absent on thorax, rudimentary on first 

 abdominal segment, better developed on second, and prominent on third 

 to seventh segments ; leaflet broad. This species is found in South 

 Africa.

 white bands. Thorax dark, with a large eye-like spot on each side of 

 the median line. Abdomen dark brown. Legs brown, unbanded. 

 Costa black with three large white spots and two smaller ones. It is 

 found in the Transvaal and North-East Rhodesia. Edwards considers 

 that Anopheles pseudosquamosus, Newst. and Cart., is identical with it.

 row white bands and white apex. Thorax dark, with white scales
