A Monograph of Culicidae. 
longer than the mid, about one and a half times its own length 
distant from it; fringe brown, costal margin very dark. 
Halteres with a pale stem and fuscous knob. 
Length .—1'8 to 2 mm. 
Habitat. —Salisbury, Mashonaland (Marshall) (79). 
Time of capture. —March. 
Observations .—One of the smallest mosquitoes, about 2 mm. 
in length. Its small size, characteristic thoracic ornamentation, 
unbanded abdomen and tarsi will at once separate it from all 
other Stegomyias. The mid scutellar lobe of the single 9 that 
I have examined was partly destroyed by the pin, but traces of 
the broad scutellar scales could be seen, and they were markedly 
present on the lateral lobes.

(Fig. 131, PL XXXIY.) 
Thorax reddish-brown, with bronzy narrow curved scales; 
pleurae dark brown, with numerous broad white scales; abdomen 
brown, with yellow apical bands; venter pure white, with four 
triangular black lateral patches, which show on the sides of 
the abdomen, and traces of a fifth. Legs unbanded, dark brown, 
femora pale at the base; ungues of the fore and mid legs of the 
9 equal, uniserrated; of the hind legs simple. Wings with a 
yellowish tinge, and with the base of the second posterior cell 
nearer the base of the wing than that of the first sub-marginal 
cell. 
9 . Head covered with flat creamy scales in the middle, 
white ones round the eyes, forming a narrow border, the rest of 
the head covered with flat black scales and a few upright forked 
black ones; clypeus black, with small flat white scales dotted 
over it; proboscis greyish-brown at the base, black at the apical 
end, extreme apex testaceous; palpi rather long, black, as long 
or longer than the head, thin, last joint apparently very long, 
but there may be a small apical joint hidden in the black scales; 
antennae dark brown, the basal joint ferruginous on the outside, 
black inside, with small white flat scales; base of second joint 
bright ferruginous, with small creamy scales, hairs blackish.
