posterior cross- vein not quite as long as the mid about its own 
length distant from it. The wings are noticeable for the fact 
that the scales are larger than in most Grabhamias. Hal teres 
pale creamy. 
Length, 4.8 mm. 
This is a biting mosquito, distributed over a wide area in 
Southern Queensland, but rare about Brisbane ; I found two 
specimens in the house at Deception Bay, and one on Taylor's 
Range ; in a few mosquitoes sent from Charleville this species 
occurs, and also in a small collection from Normanby Station, 
which points to its being commoner inland. Mr. Tryon took 
one in Victoria Park, Brisbane ; it also occurs in New South 
Wales (Masters). 
The eggs, larvae and males have not been observed. To 
the naked eye it has some resemblance to both Culex vigilax and 
Culex occidentalis ; but under the microscope the wing scales are 
seen to be very remarkable and beautiful. 
CULEX.— Linnaeus. (1758) 
Palpi of the $ short, three or four- jointed ; of the g long, 
three- jointed ; constrictions at the bases may give the $ a four 
or five- jointed and the $ a five -jointed appearance ; the last 
joint in the % is usually large ; the male may have the last two 
joints swollen, much as in Anopheles, or they may be narrower 
and the last pointed. The antennae are pilose in the plumose 
in the g , and are composed of fourteen joints in the fifteen 
in the the last two in the male being long and thin. Head 
ornamented with narrow curved scales over the occiput, and 
upright forked scales especially thick on the back of the head, 
flat scales on the sides ; thorax with narrow -curved hair-like or 
spindle-shaped scales ; scutellum with narrow-curved or spindle- 
shaped scales only ; abdomen with flat scales ; wings with small 
median scales to the veins and more or less thin linear lateral 
ones to some or all of the veins. In the wings the first sub- 
marginal cell is longer and narrower than the second posterior 
cell, and the posterior cross-vein is always nearer the base of 
the wing than the mid cross- vein. The ungues of the $ are 
equal, simple or uniserrated, of the $ unequal on the fore and mid 
legs, the larger uni- or biserrated, the smaller uniserrated or 
simple. 
The genus contains a large number of species. An attempt 
has been made by Felt to divide it up into a number of genera 
upon certain characters, which, according to Theobald, will not 
hold.
