A Monograph of Culicidae. 
an arch of them surrounding the ‘ bare space,’ two sub-median 
bare lines from cephalic end nearly to ‘ bare space ’ covered with 
‘ frost,’ so that they seem like two very fine but distinct white 
lines; scutellum brown, with pale ochraceous curved scales and 
large brown bristles; the pleura covered with white ‘ frost, 5 
and having a couple of large bunches of white flat spatulate 
scales ; metanotum brown. 
Abdomen brown, covered with rather broad flat scales, 
tending to iridescence, narrow white apical bands, and white 
apical lateral spots continuous with the scaling of the venter, 
which is white ; white apical hairs. On the last segment the 
apical band becomes much diminished on the median line, 
possible sometimes broken so as to form two spots. 
Legs as a whole brown; coxae and trochanters light and 
nearly naked, but showing the white c frost,’ femora light at 
base and on ventral aspect, a small light knee-spot minutely 
involving both sides of the joint; tibiae brown, a minute apical 
light spot involving both sides of the joint, remainder of tarsi 
all brown; all ungues small, equal and simple. 
The colouring as a whole is dark, but the scales are very 
sensitive to the position of the light, and on the legs it is almost 
impossible to determine if there be a very narrow light line on 
the ventral aspect of the tibia or not, for in some lights it is 
not apparent, and in others it appears present. The mesothorax 
shows the same trait, in that the tips of the scales become 
golden-brown, and are thus very misleading. 
Wings clear; scales brown, slender, covering the distal half 
of the wing rather heavily; cells vary somewhat in the two 
wings, first sub-marginal about a third longer and nearly the 
same width as second posterior, the stem of the former about a 
fourth the length of its cell, of the latter a little more than half 
the cell’s length ; supernumerary and mid about the same length 
and meet, posterior cross-vein slightly shorter and three times its 
length distant. Halteres light, a few brown scales on the distal 
parts of stem.
