24G A Monograph of Culicidae. 
Thorax bright testaceous brown, with narrow bronz} r -black 
rather straight scales, scattered over the surface, a median line 
of small, flat, brilliant blue scales ending about or just before 
the middle of the mesonotum ; another patch just before the 
roots of the wings, more or less in the form of a line ; prothoracic 
lobes densely covered with deep blue flat scales ; on the mesonotum 
are also two median rows of long bristles and there are others at 
the sides, in some lights two parallel paler lines follow these two 
lines of bristles; scutellum pale testaceous at the sides; middle 
lobe darker, covered with flat blue scales and with four border 
bristles, side lobes also with four bristles; metanotum pale 
ochraceous-brown; pleurae pale ochraceous, with a dense patch 
of flat bright-blue scales over the anterior legs. 
Abdomen dusky brown to almost black, the segments, 
especially the apical ones, with apical pearly-white borders, more 
or less irregular, and with clear white apical lateral spots. 
Legs with the coxae pale ochraceous; femora dark brown 
above, pale beneath ; tibiae black, with a white apical spot; 
fore metatarsi and first tarsal joints with a small white apical 
band, the remainder brown; mid legs much the same; hind 
legs with all the tarsi with apical white bands, except the. 
last, which is entirely white ; ungues equal and simple, rather 
thin. 
Wings with the veins with a single median row of dark 
brown spatulate scales and with lateral clavate and broadly 
lanceolate ones on the first, second, third, and on the fork of the 
fourth, some rather elongate, others with thin pedicils; at the 
base of the fourth and fifth long veins is a line of brilliant 
mauve scales; fork-cells short, the first sub-marginal cell much 
smaller than the second posterior cell, its base nearer the apex 
of the wing, and its upper branch close to the first long vein, 
also its stem, which runs parallel and almost touching it; the 
stem just at the root of the fork has a few large pedunculate 
lateral scales ; supernumerary cross-vein close to the end of 
the second long vein; second posterior cell larger than the 
first sub-marginal cell, its stem rather more than one-and-a-half 
times the length of the cell; posterior cross-vein not quite its 
own length distant from the mid cross-vein, close to the base 
of the fork of the fifth ; no scales at the tip of the sixth vein, 
which is much curved at the apex. Halteres with an ochraceous 
stem and dusky knob. 
Length .—2 to 2*7 mm.
