Genus Stegomyia. 
lines and white basal bands to the hind tarsi; bases of some of 
the fore and mid tarsi pale. 
9 . Head black, with two median lines of white scales 
meeting in a point in front, expanding backwards ; border of the 
eyes white scaled, and a line of pure white scales between the 
eyes ; eyes silvery ; antennae brown, with pale bands ; basal joint 
black, with a border of pure white scales ; base of the second 
joint reddish-brown ; palpi covered with black and white scales, 
the tip being white scaled. 
Thorax bright chestnut-brown, covered with very fine scales 
almost like little hairs, a thin but very distinct median line of 
white scales which forks round a bare patch just in. front of the 
scutellum, a fine curved line on each side, starting from the 
side of the thorax near the head and about the middle, bending 
in and running down the dorsum of the mesothorax to the scu¬ 
tellum ; there is also another lateral white line below on each 
side ; scutellum chestnut-brown, bordered with white scales and 
with black bristles; metanotum chestnut-brown; pleurae chest¬ 
nut-brown, with white scales. 
Abdomen coveted with black scales, showing a dull purplish 
tinge, and a few traces of ochraceous coloration in some lights, 
each segment with a narrow but very distinct basal band of 
white scales, which turns off at an obtuse angle on each side, 
forming a straight lateral oblique line on each side of the seg¬ 
ments ; on the last two segments the white scales of the venter 
come up as a narrow line and join the oblique lateral stripes ; 
posterior borders edged with pale golden hairs. 
Legs black, with white lines and bands, as follows : fore 
femora and tibiae, with three white lines of scales running the 
whole length, one ventral, the other two lateral ; base of the fore 
metatarsus white, also with white lines ; tarsi black, slightly paler 
at the base, owing to the absence of scales ; mid legs very similar, 
but the bases of the first two tarsal joints rather more distinctly 
pale ; hind legs, with the bases of the femora, quite pale, and bases 
of the first and second tarsi broadly banded white ; last two tarsal 
joints lost. Ungues of the fore and mid legs small, and not toothed. 
Wings with rather long, narrow, brown scales on the veins ; 
first sub-marginal cell very little narrower or longer than the 
second posterior cell, the stem of the latter only about half the 
length of the cell; posterior cross-vein about one and a half times 
its own length distant from the mid cross-vein. 
Length — 5 mm. (not including proboscis).
