$ . Palpi brown unbanded, the last two joints with scanty 
brown hairs on both sides, the two apical joints being darker 
than the remainder of the palpi ; antenna? banded brown and 
white, with flaxen brown plumes ; proboscis black, expanded 
apically ; thorax as in the % ; abdomen not so cylindrical as 
the % , slightly expanded apically, with six basal white bands 
as in the % , apical segment black ; segments with pale brown 
hairs laterally ; in certain lights the abdomen has a violet hue ; 
apical segment truncated and bristly as in the ? ; posterior 
border-bristles rich brown, shorter in the middle than at the 
sides ; genitalia with a spine-like process near the apex of the 
claspers ; the lateral process of the basal lobe spined, with an 
apical tuft of bristles, a broad sword-like plate and two long 
chitinous processes curved at their apices. Legs dark brown 
to black unbanded ; fore ungues unequal, the larger not very 
long, rather thick, uniserrated, curved ; the smaller more or less 
straight, curved at the tip, with a small tooth towards its base ; 
mid ungues very unequal, the larger curved, acute, simple, the 
smaller rather more than half its length, straighter, and with 
a very small tooth near the base ; hind ungues very small, equal, 
sickle-shaped and simple. 
Length, 4 to 4.5 mm. 
This is a small brown biting mosquito, common in South 
Queensland in scrubby places, but never very plentiful ; it can 
be recognised when alive at once by the position of the hind- 
most pair of legs, which are always cocked up and bent forwards 
as far as the head. When the specimens are dry, it much 
resembles starved Culex fatigans, and can only be separated 
by critical examination under the microscope. The larvae 
are found in small collections of water in scrubs ; they have 
a very long respiratory siphon. It oviposits in a small boat- 
shaped raft easily recognised by its small size from that of Culex 
fatigans.

Antennae brown, about five-sixths the length of the pro-

scales. Head brown, densely covered with golden - yellow 
scales and hairs. Proboscis uniformly covered with violet-
