posterior cross-win aluiut liiilf its length (listaiit fnmi the mid cross-vein; halteres 

 with pale stem and creamy scaled knob. 



Length. 5 to ■'}.!) nun. 



Habitat. Abyssinia (Isana. through Damot). 



Observations. Described from four females. It is ii hirge heavy built Culex, 

 very like a large C. fatigam, Wied., but can at once lie told by the dentate 

 ungues. Tlie thoracic ornamentation is marked in some very clearly, in others 

 not so much. 



A specimen sent liv Dr. Balfour from the Sobat in ^•ery damaged condition 

 seemed to be this species. 



Culex fatigans^ Wiedemann

Apparently verv abundant along the Nile and its tributaries as elsewhere. 

 Dr. Balfour has taken it on the Baro and Pibor, and reports it as by far the 

 commonest mosquito in Khartomn. I have also seen specimens from Suez, 

 Ismailia, and Cairo. 



Culex piisiihis. Bigot 

 Dipt. Exot. 4th Supp., p. 9, Mono. Culicid. II., p. 166 (1901) 

 This small thick set Culex has not occuri'ed since Bigot's specimens were 

 taken. It is evidently distinct, and comes between Culex pipiens and C. fatigans.
