83 THE MOSQUITOES OF EGYPT, THE SUDAN AND ABYSSINIA . 1S closely related to Uranotania ctzruleocephala, Theobald (Mono. Culicid., Vol. II., p. 256), but can be told at once by the head having a broad area in the middle of flat black scales, and by the thoracic markings being blue instead of white.

UranotcBnia cczruleocephala, Theobald Mono. Culicid. II., p. 256, (1901), and III., p. 302 (1903) A single female taken by Dr. Balfour on the Bahr-El-Jebel. It exactly resembles the type but small, lateral, white abdominal patches may be seen. It can at once be told from the former by the head being entirely pale blue. It has also been taken at Old Calabar, Gambia and Uganda.

A New Genus and New Species.

The \eiy cuiious male described here cannot be placed in any known genus, but without the female I prefer to leave it un-named.

Male. Proboscis black; labellae paler; palpi brown (Fig. 7), a pale band on the lower side of centre ; the apical joint, rather swollen and bent, covered with scales and a few bristles. Antenna?, plumose with a long terminal pilose segment. Head dark and small, eyes deep purplish-black; pale upright scales, not forked, over vertex and occiput; white flat scales on either side of a dark median line of scales, a few black scales on the nape. Thorax denuded, with traces of black and long golden hair-like scales; pleura? brown with white patches.

Abdomen purplish-black with basal yellowish white bands to the segments, which expand laterally and spread on* to the venter.

Legs with knee spot and long tibial bristles, pale tibiometatarsal tufts and the three last hind tarsals pale yellow; posterior ungues much smaller than the others, all apparently equal and simple.

Length. 4 mm.

Habitat. Bahr-El-Jebel, North Sudd Country.

Observations.—Described from a single damaged male which I have mounted in balsam. It is most marked owing to the curious form of the palpi which separate it from all other Culicids I have seen, or that have been described. It may be a male of some genus already named ; hence, until more specimens are obtained, I leave it unclassified.
