A Monof/mph of < ' ulicidae. 
Legs dark brown, with the under-sides of the femora pale ; 
tibiae brown, with a yellowish reflection in certain lights ; meta¬ 
tarsi basally pale banded ; first three tarsi of the mid and all 
four of the hind legs basally white 
ringed ; ungues equal and simple. 
Wings with brown scales, the 
lateral ones long, costa dark brown; 
first sub-marginal cell short, much 
narrower and a little longer than 
the second posterior cell; their 
bases opposite ; their stems nearly equal; mid cross-vein a little 
longer than the posterior cross-vein, situated from it about its 
own length distant; fringe grey ; halteres ochraceous. 
Length. —3*8 mm. 
Habitat. —Bupengary, Queensland (Bancroft) (5. 12. 1899) ; 
Gosford and S. Clifton, N.S.W. (Skuse). 
Time of appearance. —December to February. 
Observations. —Redescribed from a single 9 sent by Dr. Ban¬ 
croft from Queensland ; it answers in so many respects to Skuse's 
0. procax that I feel sure it must only be a local variety of that 
species. 
The differences are ones of colour. Skuse s specimen had a 
light umber-brown head, adorned with golden scales, and this one 
has a black head with pale scales. Skuse also describes the 
thorax as red-brown, but in Dr. Bancroft’s .specimen it is almost 
black. Beyond these differences, the insect answers exactly to 
C. procax , and I take it to be a mere local variation of that 
species. Skuse states that it is a day-flier. It is the smallest 
known Australian Culex. The two clear white spots, one on each 
side of the head, and its small size, seem to be the most 
characteristic features.
