Genus Culex. 395 



Culex hirsutipalpis. Theobald (1901). 



Mono. Culicid. L, p. 379 (1901). 



A single female from El Obeid in Kordofan sent by 

 Dr. Balfour. It is quite typical, but does not show the two pale 

 thoracic spots seen in most specimens. 



This Culex was originally described from Mashonaland ; it 

 also occurs commonly in the Transvaal, Gambia, Gold Coast, and 

 is probably existing all over Africa. 



The thorax is brown covered with deep golden-brown scales, 

 and some pale creamy ones, the latter usually form two more or 

 less distinct spots on the mesonotum, there are also paler scales 

 in front of the scutellum, over the roots of the wings, three rows 

 of black bristles, and many over the base of the wings. The 

 proboscis is deep brown at the base and towards the end, the 

 middle forming a broad pale band, the extreme apex is 

 testaceous. 



The abdomen is brown with basal semi-circular median yellow 

 patches and basal lateral white spots. 



The legs brown, the segments with apical and basal pale bands, 

 except the last tarsal in the fore and mid legs, which are all dark 

 brown. Ungues in female all equal and simple. In the male 

 the proboscis has a narrow median pale band ; the palpi are 

 brown longer than the proboscis by nearly the last two segments, 

 apical segment acuminate with a narrow yellow apical band, and 

 a broad basal one, the penultimate segment also with a basal 

 yellow band, the ante-penultimate with a broad pale band and a 

 narrow one towards its base, hair-tufts on the last two segments 

 and the apex of the ante-penultimate long and black ; fore and 

 mid ungues unequal, both uniserrate, hind equal and simple. 



The Sudan specimen measured 5 • 5 mm.

 with four basal white bands. Legs deep brown, with basal
