[ 90 ] 
Scutellum entirely white scaled. Abdomen with lateral spots. Fore legs 
with basal white bands to metatarsus and first tarsal joint; mid legs with 
white spot about the middle of femora and white scales at the apex and 
tarsus banded as in the fore leg; basal two-third of hind femora white, 
metatarsus and first three tarsal joints with basal white bands. 
Female Head. —Black; on the vertex is a large diamond-shaped patch 
of silvery scales, on either side of this are dark scales which appear black 
under a hand lens but under a 2/3 vary with the light, in a good light 
shewing bronze-green tints: the real colour of the scale if seen singly 
and not massed is olive-brown. On either side of these dark scales is a 
band of white scales followed by a band of dark scales succeeded by white, 
and along the orbital margin of either side is a single row of small white 
clavate scales. The head scales are not so broad as those on most 
stegomyia. Between the eyes the white scales are small and lanceolate. 
There are a few upright scales on the extreme margin of the occiput seen 
with great difficulty in the type but still quite evident; orbital and vertical 
bristles brown. Basal joint of antenna black, clad all round except outside 
with small silvery spindle-shaped scales, second joint with a few dark scales, 
remaining joints dark blackish-brown with black verticillate hairs. Clypeus 
black. Palpi about one-fourth the length of the proboscis, black, for the 
basal two-thirds, silvery on the apical third. Proboscis about as long as the 
abdomen, black. 
Thorax .—Prothoracic lobes black, clad with spindle-shaped silvery 
scales. Mesonotum black; shoulders clad with silvery spindle-shaped 
scales, anterior fourth covered with long silvery narrow-curved scales while 
a band of silvery scales extend transversely inwards from the root of the 
wing on either side for about one-third the total breadth, the rest of 
the mesonotum is covered with metallic-bronze narrow-curved scales. 
Scutellum light brown, narrower than the base of the mesonotum, clad 
with three patches of small flat silvery scales : these scales are relatively 
much smaller than in most stegomyiae and their ends are more rounded. 
Scutellar bristles dark brown ; there appear to be only two central bristles 
and it does not look as though any were knocked off. One specimen shews 
two the other two large and one small one. Pleurae black with patches of 
silvery flat scales. Wings clad with dark brown scales of the usual type 
linear lateral, median narrow spatulate, first fork cell narrower and slightly 
longer than second, their bases about level, the stem of the first fork cell 
about half the length of the cell; posterior cross-vein about twice its own 
length from the median. Coxae dark brown clad with silvery flat scales; 
femora and tibiae of fore legs black scaled, metatarsus and tarsus black 
scaled with a basal white band on the metatarsus and first tarsal joint; 
mid leg scaled like the fore leg except for a large silvery spot about the 
middle of the anterior surface of, and a patch of silvery scales at the apex 
of each femur; basal two-thirds of hind femora silvery-white, apical third 
black, with a patch of white at the apex above and below ; tibia black 
scaled ; rest of leg black scaled with basal band on metatarsus and first 
three tarsal joints ; fore and mid ungues equal uni-serrate, hind equal and 
simple.
