A Monograph of Culicidae. 
forked scales in the middle, black or grey at the sides; eves 
black, with a narrow silvery border ; antennae dark brown, basal 
joint dark, pubescence white, verticillate hairs brown, basal and 
next few segments with white scales; palpi densely scaled with 
black scales, with two, three, or four rings of w T hite scales; the 
apex usually white ; the white scales are at the apices of the joints ; 
proboscis black, densely scaled at the base, about as long as the 
palpi; in some the proboscis is slightly testaceous at the tip. 
Thorax dark brown, with grey sheen in the middle, adorned 
with dark longitudinal lines, and with scattered pale creamy to 
yellowish curved hair-like scales; scutellum dark in the middle, 
paler at the sides, sometimes showing a testaceous tinge, at others 
a grey hue; border-bristles chestnut- to dark-brown; metanotum 
deep brown; pleurae brown, with a few greyish areas. 
Abdomen deep black, with a slight ochraceous tinge in 
places covered with brown hairs. 
Legs ochraceous, clothed with deep brown scales, with a 
bright ochraceous sheen in some lights; the apex of the meta¬ 
tarsi and first two tarsal joints of the fore- and mid-legs apically 
banded white, and also, to some extent, may be seen a white 
basal patch on the metatarsi. In the hind legs the metatarsi 
are broadly white banded at the base and apex, and the apex of 
the first is also banded white ; the second is almost all white, 
save a small black basal band, last two pure white; ungues 
dark brown, equal and simple. 
Wings densely clothed with black and yellow scales, the 
former predominating, so that the wings look sooty-black. The 
scales are broadish and spindle-shaped. The black scaled costa 
has two small white spots, one near the apex ; this spot extends 
on to the first long vein and the upper branch of the first sub¬ 
marginal cell; the second costal spot just touches the first 
long vein. There are also small pale scaled areas on the lower 
branch of the first sub-marginal cell, on each of the branches of 
the second posterior cell, a few pale scales on the bases of the 
fork-cells, and on the third long vein. On the upper branch of 
the fifth are two small pale areas, the lower branch and stem 
being mostly pale scaled. The sixth pale scaled, with two black 
spots. Wing fringe entirely brown, the border-scales yellowish. 
First sub-marginal cell considerably longer and a little narrower 
than the second posterior cell; its base a little nearer the base of 
the wing than that of the latter; its stem about two-thirds the 
length of the cell. Stem of the second posterior cell longer than
