THE MOSQUITOES OF EGYPT, THE SUDAN AND ABYSSINIA 71 Genus Mucidus, Theobald. Mono. Culicid. I., p. 268 (1901) Mucidus africanus, Theobald. Mono. Culicid. I., p. 274, and III., p. 134 (1903).

(Plates II., Fig. 1; IV., Fig. 2; V., Fig. 6) A single female was sent by Colonel Stanton to Dr. Balfour, taken in Khartoum. It is undoubtedly a variety of my M. africanus. Dr. Balfour describes in bis notes the cross-veins as being like a Culex. I have mounted the wings of the specimen he sent, and find them quite normal. I may here point out a character I have missed in this genus, namely, that the third long vein is very near the second (vide photo of wing, Plate II., Fig. 1). It has also occurred in Uganda. (Wadelai, one female.)

Genus Stegomyia, Theobald Mono. Culicid. I., p. 283 (1901) Stegomyia fas data, Fabricius.

(Plate VI., Fig. 2) Syst. Anti. 36, 13 (1805) Fabr.; Mono. Culicid. I., p. 289 (1901) and III., p. 141 (1903). This yellow fever carrier has been taken at Ismailia and Port Said by Major Ronald Ross, and it also occurs in Khartoum and on the river steamers.

Other localities Pibor, Cairo.

Genus Etokleptiomyia, nov. gen.

Head clothed with a mixture of narrow-curved scales, upright forked ones and small loose flat scales all over ; antenna? scaly on the basal joints. Thorax with scales of mesonotum narrow and curved, those of the scutellum fiat and small. Abdomen clothed with flat scales. Wings with very marked heart-shaped scales (Plate II., Fig. 2), on the basal halves of the second, fourth, fifth and sixth veins; on the first long vein, base of second and fourth also with more or less Mansonia-like scales and along costal border also, scales on the apical halves of the veins pedunculated, clavate, peduncles very short; costa spiny ; fork-cells moderately long.

This forms a very distinct genus, easily told by the curious heart-shaped scales on the wings. The proboscis seems very weak.

A single species only is so far known, which was taken by Dr. Balfour. The Mansonia-like scales are not exactly as in that genus, ■‘but approach them very closely.

Etorleptiomyia mediolineata, n. sp.

Head yellow with a black patch on each side; proboscis brown, unhanded. Thorax black with narrow-curved golden scales. Abdomen black with a median line of yellow scales. Legs brown, femora yellow beneath, tibia? mottled with yellow, metatarsi and tarsi with yellow apical bands except the last. V ing» w ith dark brown scales basally and along the costal area.
