the smaller with a minute tooth ; hind ones equal and simple. 
Wings with rather blunter and broader lateral scales to the 
veins than in the ? ; both fork-cells short, the base of the second 
posterior cell nearer the base of the wing than that of the first 
sub-marginal cell ; stem of the latter equal to the length of the 
cell ; stem of the second posterior not quite so long as the cell ; 
posterior cross-vein nearly twice its own length distant from 
the mid cross-vein and somewhat longer. 
Length, 4 to 4.5 mm. 
Mr. Theobald makes a sub-species, but I do not think it 
will hold, as there is great variation in the scale ornamentation 
in this extremely plentiful insect. 
Habitat : N.S. Wales (Masters and Skuse), Southern Queens- 
land (Bancroft). 
This is another extremely plentiful and annoying mosquito, 
biting by day and night ; found along the sea-coast, in association 
with Culex vigilax, from which it is easily recognised by the 
banded proboscis and black legs. It comes into the house ; 
will live well in confinement for a month or more ; oviposits in 
a boat-shaped raft similar in appearance to that of Culex fatigans. 
A mosquito raft on salt water will turn out to be this species. 
It breeds in sea-water, and fresh-water lagoons and wells. This 
species and Culex vigilax are the most troublesome and abundant 
native mosquitoes in Southern Queensland. It will, under 
exceedingly favourable conditions, occasionally act as host for 
the dog filaria. 
Culex pseudomelanoconia. — Theobald (1907). 
$ . Head deep brown, with narrow-curved golden-brown 
scales in the middle, flat grey ones at the sides, with ochreous 
upright forked scales at the middle, dark ones at the sides, and 
flat grey ones laterally. Proboscis and palpi dark brown. An- 
tenna and clypeus deep brown. Thorax deep brown with 
narrow-curved golden scales, somewhat smaller over the humeral 
area, with two median bare lines showing as two dark areas ; 
bristles brown, somewhat golden apically ; scutellum brown, 
with golden narrow-curved scales ; metanotum deep brown ; 
pleurse greyish-brown to brown. Abdomen deep blackish- 
brown with golden-brown lateral and posterior border-bristles ; 
venter pale scaled. Legs deep brown with violet reflections, 
bases of the femora pale, ungues small, equal and simple. Wings 
with typical deep brown Culex scales, dense on the apical portions 
of the veins ; the first sub -marginal cell much longer and slightly 
narrower than the second posterior cell, its base much nearer 
the base of the wing, its stem a little less than half the length 
of the cell ; stem of the second posterior nearly as long as the 
cell ; the posterior cross-vein much shorter than the mid, about 
twice its own length distant from it, the mid cross- vein the largest 
of the three.
