THE MOSQUITOES OF EGYPT, THE SUDAN AND ABYSSINIA 7 1 



Genus MuciDUS, Theobald. 



Mono. Culicid. L, p. 268 (1901) 



Mucidus africanus, Theobald. 



Mono. CuUcid. I., p. 274, and III., p. i;3-l (1908). 



(Plates IL, Fig. 1 ; IV., Fig. 2 ; V., Fig. 6) 



A single female was sent by Colonel Stanton to Dr. Bulfuur, taken in 



Khartoum. It is undoubtedly a variety of my M. africanus. Dr. Balfour 



describes in his notes the ci'oss-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 IL, Fig. 1). It has 



also occuiTcd in Uganda. (Wadelai, one female.) 



Genus Stegomyia, Theobald 

 Mono. Culicid. I., p. 283 (1901) 

 Stegomyia fasciata, Fabricius. 

 (Plate VI., -Fig. 2) 

 Syst. Antl. oti, lo (1805) Fabr. ; Mono. Culicid. 1., p. 289 (1901) and 

 III., p. Ul (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 Etoklei'tiomyia, nov. gen. 



Head clothed with a mixture of narrow-ciu'ved scales, upright forked ones 

 and small loose flat scales all over : antenna? scaly on the basal joints. Thorax 

 with scales of mesonotum narrow and cui'ved, those of the scutellimi flat and 

 small. Abdomen clothed with flat scales. Wings with very marked heart-shaped 

 scales (Plate IL, Fig. 2), on the basal halves of the second, fom-th. fifth and 

 sixth veins ; on the first long vein, base of second and fourth also \\ith more 

 or less Mansonia-like scales and along costal border also, scales on the apical halves 

 uf the veins pedimculated, clavate, pedimcles 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, wliicli Avas taken by Dr. Balfour. 

 "The Mansonia-hke scales are not exactly as in that genus, but approach them 



very closely. 



Etorleptiomyia mediolineata, n. sp. 



Head yeUow with a black patch on each side; proboscis brown, unhanded. 

 Thorax black with narrow-cui'ved golden scales. Abdomen black with a median 

 line of yellow scales. Legs brown, femora yeUow beneath, tibia' mottled with 

 yellow, metatarsi and tarsi with yellow apical bands except the last. Wings -with 

 dark broAvn scales basaUy and along the costal area.
