It is one of the most marked and beautiful of the Australian 
Culicidae, and can at once be told by the four broad, deep rich 
brown lines on the mesothorax and the pale golden-grey scaled 
intervening spaces; the four dark lines are due to the dark 
surface being clothed with bronzy-black scales. The abdomen is 
also peculiarly marked, the median darker banding to the 
segments being more pronounced in some specimens than in 
others. The palpi are distinctly five-jointed and large even for 
a Culex. 
No males have been received.
