NOTES ON SOME TRANSVAAL MOSQUITOES. 109 



species all being founded on males. The only other African 

 member of this genus known is F. nigripes, Theobald, from 

 Sierra Leone (Mono. Culicid. vol. iv. p. 578, 1906), which differs 

 from the Transvaal species in having a banded abdomen, the 

 basal white bands being very prominent in the Sierra Leone 

 insect. The female wing-scales agree with those of the male in 

 this genus, and the discovery of the female does not necessitate 

 adding anything to the definition of the genus. 



' JEdes inconspicuosus , nov. sp. 



Head dull ochreous-brown, paler than the brown thorax ; abdo- 

 men, legs, and proboscis, all dark brown. 



5 . Head deep brown, with small, rather loose, flat scales over 

 most of the area, some dull ochreous, others brown, and others with 

 a dull violet tinge, the ochreous hue prevailing, behind a large patch 

 of narrow-curved ochreous scales, thin ochreous upright forked- 

 scales behind, brown in front ; chsetae long, deep brown ; palpi rather 

 small, proboscis and clypeus deep brown ; antennse deep brown. 

 Thorax deep brown, with narrow-curved pale brown scales, showing 

 some ochreous reflections ; chaetae deep brown ; scutellum pale 

 brown, with narrow-curved pale scales and five deep brown border- 

 bristles ; metanotum deep shining brown ; pleurae grey. 



Abdomen deep brown, with dull violet reflections ; on the venter 

 the segments are pale at their bases ; border-bristles pale brown. 



Legs deep brown, unhanded ; the tarsi showing dull ochreous 

 hues ; ungues small, equal, much curved and simple. 



Wings with long thin brown lateral vein-scales ; fork-cells long, 

 the first submarginal cell much longer but only slightly narrower 

 than the second posterior cell, its base considerably nearer the base 

 of the wing than that of the latter, its stem about one-fourth the 

 length of the cell ; stem of the second posterior nearly as long as the 

 cell ; posterior cross-vein nearly three times its own length distant 

 from the mid. Length 3 mm. 



S" . Antennffi plumose, plume-hairs brown, internodes grey ; 

 palpi very small, brown. Head, thorax, and abdomen as in the 

 female, but the abdominal segments are deeply constricted at the base 

 and the scales at the apical edges show dull ochreous reflections (not 

 banding). Wings much as in the female, but the stem of the first 

 submarginal cell only one-third the length of the cell, and the 

 posterior cross-vein only about one and a-half times its own length 

 distant from the mid. Ungues of fore and mid legs unequal, uni- 

 serrate ; hind small, equal, and simple. Length 3 mm. 



Habitat. Transvaal (Mr. Simpson). 



Observations. — Described from a single female and male. A 

 small, brown, inconspicuous mosquito, the only species of this 

 genus as yet recorded from Africa.
