ones, with a dense white apical tuft ; proboscis ochraceous, with 
a few black scales at the base, and a black apex ; clypeus deep 
brown ; antennae deep brown, the basal joints with small fiat 
pale scales. 
Thorax deep brown, with narrow-curved golden-brown scales, 
ornamented with some broader white ones in front, and similar 
scales forming two distinct round spots about the middle of the 
mesonotum, similar pale scales at the edges of the mesonotum 
and in front of the scutellum ; bristles rather thick laterally, deep 
brown; scutellum covered with almost white narrow-curved 
scales, forming three dense patches ; border-bristles brown, six to 
the mid lobe ; metanotum deep brown ; pleurae deep brown, with 
white scales. 
Abdomen black, covered with deep violet-black scales, with 
basal white bands ; the first segment has two large patches of 
black scales ; the second has the basal white band passing down 
two-thirds of the middle of the segment ; in the apical segments 
the bands spread out laterally ; the ovipositor rather long, black ; 
venter white, with narrow black apical scales. 
Legs deep brown, mottled with white and creamy scales, 
especially on the metatarsi, first two tarsal joints of the fore and 
mid legs with broad basal white bands ; in the hind legs all the 
joints with broad basal white bands ; ungues of the fore, mid, and 
hind legs equal, thick, uniserrated. 
Wings with the veins covered with typical brown Culex scales ; 
the first sub-marginal cell longer and narrower than the second 
posterior cell, its base very slightly nearer the base of the wing, 
its stem more thanhalf the length of the cell; stem of the 
second posterior as long as the cell ; posterior cross-vein nearly 
twice its own length distant from the mid; the first and 
third longitudinal veins darker than the rest. Halteres pale 
ochraceous. | 
Length.—5 mm. 
Habitat.—Pretoria (Dr. Theiler). 
Time of capture.—February and March. 
Observations.—It is very distinct, and easily identified by 
the speckled legs and broad basal white banding; the densely- 
scaled apices of the palpi and the dense scutellar scales are also 
characteristic. Described from a number of specimens sent by 
Dr. Theiler (per Col. David Bruce, F.R.S.).
