THE MOSQUITOES OF EGYPT, THE SUDAN AND ABYSSINIA

It is closely related to Ui'anotisnia cceruleocephala, 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. 



Uranotcenia cceruleocephala, 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 fonner 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 very curious male described here cannot be placed in any known genus, 

 but without the female I prefer to leave it un-named. 



Male. Proboscis black ; labella? paler ; palpi brown (Fig. 7), a pale Imnd 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-lilack ; pale upright scales, not forked, over 

 vei'tex 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 ; 

 pleuras liroAvn with white patclies. 



Abdomen purplish-black with basal yellowish white bands 

 to the segments, whicli expand laterally and spread on to the 

 venter. 



Legs vni\\ knee spot and long tibial bristles, pale tibio- 

 metatarsal 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 fi'om a single damaged male which I have mounted 

 in balsam. It is most marked owing to the curious form of the palpi wliicli 

 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.
