206 A Monograph of Culicidae. 
hind tibiae about one-third longer than the hind metatarsi ; 
ungues equal and simple, moderately curved. 
Wings with typical brown Culea scales ; the first sub-marginal 
cell a little longer and narrower than the second posterior cell, 
its base nearer the base of the wing, its stem about one-third the 
length of the cell ; stem of the second posterior about two-thirds 
the length of the cell; posterior cross-vein rather longer than 
the mid, about its own length distant from it ; halteres ochraceous, 
with a faintly fuscous tinge to the knob. 
Length.—5 mm. 
Huabitat.—Jenolan Caves, New South Wales (Dr. Bancroft) ; 
Murrumbidgee, New South Wales (Skuse) ; Bupengary, South 
Queensland (Bancroft) ; Condobolin, N.S.W. (Froggatt). 
Time of capture.—October and November. 
Observations.—Four ?’s have been sent by Dr. Bancroft from 
New South Wales which are undoubtedly the species Skuse 
described as Culex sagaz. Wis description applies exactly except 
for a slight difference in the relative lengths of the fork-cells. 
Skuse says “‘ the first sub-marginal is scarcely longer and much 
narrower than the second posterior.” In the specimens I have 
examined it is decidedly longer. Again, he says, ‘“‘the middle 
rather longer than the posterior transverse vein, placed rather 
less than the length of the latter in front of it.” In the specimens 
I have examined the posterior is quite its own length distant 
from the mid. These minor differences, I think, need not be 
considered, as it is almost impossible to say the exact relative 
lengths and distances of the veins in the wings unless they are 
mounted fiat and measurements made, and even then in some 
specimens there is considerable variation. In the present species 
the thorax is evidently subject to variation ; in one specimen 
from which this description is compiled the thorax is distinctly 
ornamented, in others it is scarcely so, but in all there are pale 
scales on and before the scutellum. | 
The male is described in Vol. IL., p. 87.

(Mono. Culicid. IT., p. 88, 1901.) 
Additional localities—Janolan Caves, New South Wales 
(Froggatt) ; South Queensland (Bancroft). 
Note.—The fork-cells of the Australian specimens seem to be 
relatively longer than the New Zealand specimens, but they are 
undoubtedly the same species.
