74 THE MOSQUITOES OF EGYPT, THE SUDAN AND ABYSSINIA proboscis black. Thorax dark brown ornamented with brown and golden brown narrow-curved scales, the golden brown forming more or less distinct linear ornamentation and a curved line on each side in front of the wings, which surrounds a dark area in front of each wing. Abdomen black with basal creamy bands. Legs brown unbanded.

Female. Head brown, clothed with rather dense pale narrow-curved scales which lie uniformly pointing forwards, a few still paler very small flat scales laterally and long thin bifid upright forked-scales over the greater part, those placed laterally jet black, those in the median area dark brown to yellowishbrown according to the rays of light; palpi thick, three distinct small basal segments dull testaceous, the fat apical segment as long as the three basal ones and black scaled; there may be a minute nipple-like apical segment, but if so it is hidden in scales; proboscis and clypeus deep brown.

« Thorax dark brown, ornamented with dull golden and deep rich brown narrow-curved scales; the dark scales form two prominent oval areas, one in front of the base of each wing, the dull golden scales bordering them; the latter are also more or less placed in lines along the middle of the thorax and others at the sides above the pleurae, others, almost creamy, in front of the scutellum; scutellum paler brown than the mesonotum, with pale narrow-curved scales and black border-bristles, seven to the mid lobe; metanotum black; pleurae black with three patches of white scales.

Abdomen black with black scales and creamy basal bands, the last two spreading out laterally ; venter all creamy yellow.

Legs deep brown, unbanded, traces of a pale knee spot and a creamy apical spot on the hind tibiae.

* \\ ings with typical brown Culex scales; the first sub-marginal cell considerably longer and slightly narrower than the second posterior cell, its base much nearer the base of the wing than that of the latter, its stem short, rather less than one-fourth the length of the cell; stem of the second posterior about two-thirds the length of the cell; posterior cross-vein rather more than its own length distant behind the mid cross-vein; halteres with reddish-brown stem, fuscous knob with a few grey scales.

Length. 4.5 mm.

Habitat. Sennar, Blue Nile.

Observations. Described from a single female. It resembles at first sight (. J at cyans but the paler scaled head and the numerous long upright forkedscales separate it, the thorax too is distinctly ornamented, the two dark ocellate aieas being most noticeable. I he palpi may be five-jointed, but are heavily scaled so that a small apical segment cannot be seen, the three small basal segments aie \ci) distinct. The last tarsals are gone so that the characters of the ungues cannot be given.
