414 GNATS OK MOSQUITOES — CHAPTER XIII 



I have seen the type in the Jardin des Plantes, and this is certainly 

 a most characteristically marked species. It is rather smaller than 

 C. pipiens, and the proboscis is rather darker at the tip and base than 

 in the middle. The eyes are black without any sign of lighter margin ; 

 the antennae brown. The thorax and abdomen are absolutely as 

 described, and the markings of the latter are very characteristic ; the 

 venter pale with the hinder borders of the segments mottled black. The 

 banding of the tarsi is so inconspicuous that it might easily be over- 

 looked. The wings have the veins clothed with alternate white and dark 

 brown scales, the fringe of the internal border being drab ; the second 

 posterior cell is shorter, but a good deal wider than the first sub- 

 marginal. 



Habitat. — Algeria.

Tarsi black above, paler on the last joints, with very broad 

 and distinct white basal bauds on all the dark joints, and with 

 signs of them on the paler ones. Thorax dark brown, clothed 

 with deep chestaut scales, and adorned with others of a creamy 

 tint, arranged to form a median line and four spots. x\bdomen 

 nearly black, with basal yellowish bands spreading laterally, 

 and nearly joined in the middle by large apical spots, especially 

 prominent on tne hinder segments. Tarsal claws as in C. albo- 

 annulatus. 



Head with rows of dark brown, yellow, and creamy scales, and whitish 

 orbits ; palpi of ? , dark brown, white at apex ; oi $ , with four yellow 

 bands, one of Avhich is close to its base. Legs pale above, and dark on 

 the tibia, which has a broad white basal band, with small white knee- 

 tufts. PleuriE brown, with small white patches. Halteres pale yellow 

 venter marked with black, white, and yeliow scaled patclies. Length. — 

 i to 4*5 mm

Note. — The only Culex with at all similar abdominal markings is 

 Mr. Theobald's Albolineatus, but that has mibanded tarsi.
