A common biting mosquito in New South Wales and Vic- 
toria ; uncommon in Southern Queensland ; it is rather a hand- 
some species, not unlike Culex rubithorax but larger, and with 
more pronounced banding of the legs. I bred it from mixed 
larvae obtained from wells at Deception Bay ; it also occurs 
in association with the larvae of Scutomyia in crevices of scrub 
trees, holding a little water, on Kedron Brook. Oviposits in 
confinement ; eggs laid singly, long oval, black, with silvery 
mesh work pattern.
