Subgenus Barraudius, nov. 



First joint of hind tarsus distinctly shorter than the tibia. No flat scales on top 

 of head adjoining eyes. Side-pieces of male hypopygium with numerous small 

 scales on the outer side ; lobe situated scarcely beyond the middle, without flattened 

 plate, and with only two or three stout spines. Clasper without subapical spiny 

 crest. Larval mouth-parts normal, not modified for predacity. Siphonal hair 

 tufts arranged mid-ventrally in a single very slightly zigzag line which runs the 

 whole length. Anal segment short, as in typical Citlex. Type species : Cidex 

 pusillus (Macq.), Storey.

The erection of this subgenus is necessary for the reception of two small obscure 

 species from the eastern Mediterranean region. By several of the characters enumer- 

 ated above they appear to be more distinct from typical Culex than any other groups 

 occurring in the Old World.

Apart from the tarsal character mentioned in the key, the female of this species 

 is not easy to distinguish from the unhanded variety of C. pipiens. There is, however, 

 no connection between the two species, which are as widely separated in the structure 

 of the male hypopygium as any two species of the genus. The average size is smaller
