VIIl] GENERA OF CULICIN^ 



109 



Edwards divides the Culicinae into two main groups : 



(i) Culex group. Eggs laid in masses ; last segment of 



female abdomen broad, immovable ; claws of female never 



toothed. 



Genera : Culex, Tainiorhynclms, mdomyia, Theobaldia, UranotcBnia. 



(2) Aedex group. Eggs laid singly; last segment of 

 female abdomen narrow, usually completely retracted into 

 the penultimate ; claws of female, at least on the four anterior 

 legs, nearly always toothed. 



Genera : Mucidus, Psorophora, Janihinosoma, Ochlerotatus, Stegomyia, 

 Aides. 



The following scheme is that of Edwards, giving the chief 

 characters of the more important genera.
