VIII] GENERA OF CULICIN^E 



Edwards divides the Culicinae into two main groups : 



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

 female abdomen broad, immovable ; claws of female never 

 toothed. 



Genera : Culex, Taniorhynchus, JEdomyia, Theobaldia, Uranot&nia. 



(2) Aedes 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, Janthinosoma, Ochlerotatus, Stegomyia, 

 Aedes. 



The following scheme is that of Edwards, giving the chief 

 characters of the more important genera.
