Genus Stegomyia . 
deep black, unbanded, the basal joint with silvery-white flat 
scales; clypeus black; palpi black scaled, the apices of the last 
two segments being white scaled above, and there are also a 
few white scales on their whole upper surface; proboscis rather 
long and thin, deep black. 
Thorax deep brownish-black to almost jet-black, densely 
covered with narrow curved scales, applied to the surface some¬ 
what closely ; those on the major area are deep brownish-black, 
there are two median nearly parallel creamy-yellow scaled lines, 
which extend right back to the scutellum and which become 
almost white before reaching it, then two pairs of lateral curved 
lines of similar colour which die out about the middle of the 
mesonotum, the innermost pair being slightly the longer; just 
beneath and in front of the roots of the wings is a white scaled 
spot and numerous pale bristles projecting over their roots; 
scutellum brown, with small flat black scales, and a few grey 
ones on the middle of the mid lobe ; posterior border-bristles 
rather pale, five to the mid lobe ; metanotum deep chestnut- 
brown ; pleurae black, with patches of pure white scales. 
Abdomen steely black, covered with dusky brownish-black 
scales; first and second segments unbanded, the third to the 
sixth with narrow creamy basal bands, the seventh and eighth 
showing pure silvery-white basal bands, the seventh rather 
incomplete, all the segments with pure silvery-white lateral 
spots, which show dorsally on the fifth to seventh segments ; 
these lateral spots are median and their scales rather project 
ventrally; posterior border-bristles pale golden-brown, longest 
at the sides of the segments ; venter black, the white lateral 
spots, however, showing very prominently on the venter when 
the abdomen is empty. 
Legs with the coxae „ dark with some white scales; femora 
deep brownish-black, white scaled at the base and partly beneath, 
apex pure white, and there is also a pure white round spot on 
one side on its apical half; tibiae deep brownish-black with pallid 
bristles; metatarsi basally white, those of the hind legs but little 
more than half the length of the hind tibiae ; first tarsal joint of 
the fore and mid legs basally white, remainder black, in the hind 
legs the first and second tarsi are broadly banded with white at 
their base (the banding is apparently not always complete), last 
two tarsi black ; ungues equal and simple. 
Wings rather dusky brown, the veins clothed with brown 
scales, the lateral ones long but rather broader than in Calex ;
