This mosquito is never plentiful, yet a few specimens can 
be obtained any day biting in forest country round about Moreton 
Bay. It is about the size of Culex vigilax, from which it can be 
distinguished by its ruddy thorax, and from Culex occidentalis 
by its smaller size, and from Culex cylindricus by the banded 
legs. Nothing is known of the life history.
