Stegomyia punctolateralis. — Theobald (1903). 
2 . Head covered with flat bronzy-brown scales, and a pale 
almost white, border around the eyes. Palpi, proboscis, clypeus 
and antennae deep black. Palpi slightly clavate, much contracted 
at the base, apical segment minute. Thorax black, with bronzy- 
brown narrow-curved scales, paler almost grey ones behind 
and at the sides forming lateral pale lines, and a narrower one 
just over the roots of the wings ; prothoracic lobes white scaled, 
separated ironi the rest of the thorax by a prominent black line ; 
pleurae densely white scaled ; scutellum with small flat grey 
scales and brown border-bristles, four to the mid lobe ; metanotum 
deep brown. Abdomen deep brown with violet reflections, 
in some lights under the microscope bright violet, each segment 
with prominent apical lateral creamy spots, which in some seg- 
ments spread almost across the apical borders so as to form 
prominent pale lines, but they never quite meet, except in the 
penultimate segment ; the first segment testaceous, with large 
dense black scales in two confluent spots, with brown bristles ; 
border-bristles very short, pale brown, shining apically. Venter 
creamy- white ; the apical spots are very pronounced on the 
ventral surface in dried specimens. Legs jet black ; under 
surface of femora, tibiae, and first hind tarsal silvery-white ; 
ungues small, equal and simple. Wings with brown scales ; 
fork-cells of moderate length, the first sub-marginal cell con- 
siderably longer and narrower than the second posterior cell, its 
base the nearer to the base of the wing ; stem of the first sub- 
marginal cell more than half its length ; stem of the second 
posterior cell nearly as long as the cell ; posterior cross- vein 
about twice its own length distant from the mid cross-vein. 
Halteres with dull testaceous stem and fuscous knob. 
Length, 4.5 mm. 
$ . Thorax and abdomen as in the $ , but the abdomen 
narrower and the apical lateral spots not quite so prominent. 
Basal lobes of genitalia densely bristly, bristles large, and arise 
from distinct papillae ; claspers long and thin, simple. Antennae 
deep brown, with deep brown plume-hairs, pale banding more 
or less noticeable ; probosics black ; palpi shorter than the 
proboscis, deep blackish-brown, no hair tufts, the last two seg- 
ments of nearly equal length, the apical one slightly shorter and 
with terminal bristles. Legs as in the ? ; fore ungues unequal, 
the larger uniserrated, the smaller simple ; mid ungues unequal, 
both simple ; posterior ones very small, equal and simple, much 
curved. Wings with brown - scales ; the first sub-marginal cell 
longer and narrower than the second posterior cell, the base 
nearly level with that of the latter ; stem of the first sub-marginal 
cell about one- third the length of the cell ; stem of the second 
posterior about two-thirds the length of the cell ; posterior cross- 
vein considerably longer than the mid and more than twice its 
length distant from it.
