This is the " Scotch Grey " ; it is a magnificent insect under 
the microscope ; common throughout the year all over Queens- 
land, but especially along the coast, and extending into N.S. 
Wales, where it is sometimes called " Hexham Grey." It is a 
vicious biter ; does not live in confinement. It oviposits singly, 
the eggs are large, oval, black in colour, pitted and float on their 
side. The larvae are to be found plentifully in salt-water swamps, 
especially in stagnant pools of water left by the high spring tides ; 
when there is no salt water available this mosquito will oviposit 
in fresh water ; the larvae devour other larvae, but not to a great 
extent.
