Anopheles flaviceps, sp. nov. 



Head with the integument rather hght yellowish, especially when viewed from in 

 front. Erect scales mostly brown, a small area of white ones in the middle towards 

 the front, and in front of these a few long, narrow recumbent scales, not forming 

 a definite frontal tuft. Many light brown bristles between the eyes ; border bristles 

 dark. Antennae with the basal joint yellow ; in female with a few small scales on the 

 second joint ; male plumes light brown. Female palpi very slightly longer than the 

 proboscis, thin, with appressed scales ; narrow whitish rings at the tips of the first 

 three joints, just extending on to the bases of the succeeding joints ; tip of last joint 

 dark. Second joint slightly longer than the first, slightly shorter than the third 

 and fourth together ; fourth joint less than half as long as the third. [Male palpi 

 missing.] Proboscis dark, except for the labella. 



Thorax rather light yellowish, darker in the females (perhaps through discoloration). 

 Mesonotum somewhat shining, not darker at the sides, with light bristles, and in the 

 middle with rather numerous, very narrow hair-like scales. Prothoracic lobes rounded, 

 not mammiUate, without scales. Prosternal hairs, five or six. 



Abdomen light brown, with narrow dark bands in the male ; hairs pale ; no scales. 

 Male hypopygium : Basal spines, five or six, all rather strong, in a loose, irregular 

 cluster ; one distinctly distal to the rest and much longer, iDut not more slender. 

 Claspettes pointed ; a long and fairly strong apical hair, half as long again as the club, 

 which is normal in shape, but much more basally placed than the hair ; no accessory 

 hairs discernible. Tip of mesosome with about five rather narrow leaflets ; the longest 

 0-55 as long as the mesosome. 



Legs dark ; extreme tips of femora and tibiae and extreme bases of tibiae pale ; 

 on the front and middle legs the tarsal articulations are also just perceptibly pale 

 under a strong lens. All femora slender, cylindrical. 



Wings : Costa dark on basal two-fifths, in one wing of one specimen with a small 

 pale spot included near the base ; apical three-fifths with four yellowish patches 

 alternating with three dark ones, of which the third is the smallest, the first being 

 distinctly larger than the adjacent light ones. A small dark spot at the wing-tip 

 opposite apex of upper fork-cell. First vein light with four dark patches, the first 

 being below the apical part of the dark basal two-fifths of the costa, the others below 

 the remaining dark costal spots. Remainder of wing without conspicuous markings, 

 but there are pale areas round the cross-veins, and the bases of the fork-cells, the base 

 of the second vein, the middle half of the third vein, and the extreme tips of the 

 second, third and fourth veins are also pale. Vein-scales linear, rather short and 

 not very dense. 



Anglo-Egyptian Sudan : Erkowit, 5.vi.l917, 1 (^ (type), 1 $, also 1 $ from the 

 same place, 22.V.17 {H. H. King). 



Type in the British Museum, presented by the Imperial Bureau of Entomology. 



Apparently most nearly allied to A. turkhitdi, Liston, and A. hispaniola, Theo. 

 (which may be a local form of A. turkhudi), but differing in the paler colour of the 

 integument, especially of the head, almost obsolete frontal tuft, more numerous 

 prosternal hairs, more shining mesonotum, and somewhat less conspicuous wing 

 markings ; also in the male hypopygium in the more pointed claspettes, which have 

 no accessory hair and a more basally situated club, and in the stronger detached 

 basal spine.
