NEW MOSQUITOES FROM THE SUDAN 
and anotlier below running from the base of the wings forward for a short distance, looking 
somewhat paler than the others in certain lights; the median and lateral lines of chtetae 
dark in front, becoming golden, longer and denser behind, the median row ceasing before the 
scntellnm ; scntellnm paler than the mesothorax, with narrow-cnrved pale scales and border- 
bristles either dark or golden according to the light ; metanotum brown, with grey reflections 
at the sides and apex. Pleurae dark, with one longish area of broadish pale scales passing 
down to the base of the first pair of legs, a smaller pale-scaled area behind. 
.1 hdomen : with the basal segment, pale ochreons, with very pale scales and one or two 
scattered dark ones ; the second, third, fourth and fifth segments with broad basal pale-scaled 
areas and a bi’oad median area of pale scales, separating the dark-scaled lateral areas, the 
sixth with still wider basal and median pale areas, and the seventh with a broad median pale 
area and a narrow’ black line on each side; posterior border-bristles thin and pale, and there 
are also thin lateral bristles; a paler-scaled lateral line runs the whole length of the body 
w’ith traces of darker scaled patches below ; venter pale. 
Legs: with ochreons scales and a few scattered dark ones, tarsi mostly dark-scaled : all 
the parts paler below, traces of pale knee spots ; femora, tibiie and metatarsi with short 
bristles, pale in some lights, dark in others; hind tibia; longer than the hind metatarsi; 
ungues all equal and uuiserrate. 
; with faint yellowish tinge: the costa with yellow’ scales and the base of the first 
long vein with some yellow scales, rest mostly dark, in certain lights the lateral scales of tlie 
second and fourth veins are pale ; fork-cells of nioderate length, the first sub-marginal longer 
and narrower than the second posterior, its base very slightly nearer the base of the wing 
than that of the second jjosterior, its stem a little more than half the length of the cell ; 
stem of the second posterior about as long as the cell; posterior cross-vein about its own 
length distant from the mid, which is the same size. 
Length : 5 mm. 
$—Thorax : as in the but the median pale line has a fine dark central line. 
Head: W’ith rather larger grey scales showing ochreons colours in some lights, and a 
median bare line; upright fork-scales dark at the back, brow’n in front; some long, straight, 
dark duet®, paler in median region. Antenme with flaxen j)lume-hairs, apical segments 
long, dark, not plumose ; palpi long, the two apical segments of about equal length, thick ; 
the apical one rather narrow towards the tip, which is blunt, ochreons basally, dusky tow’ards 
the tips, hair-tufts flaxen and brown, of moderate size, apex of the antepenultimate segment 
dark-scaled, the penultimate with creamy scales on one portion. 
Abdomen: much as in the $ but W’ith more scattered pale scales, hairs brownish. Legs 
darker than in the the femora show’ a more distinct pale line ; fore ungues unequal, both 
uniserrate ; mid unequal, both uniserrate ; hind unequal, but simple. Wings with the first, 
third and fourth long veins dark-scaled, the costa w’ith many yellow’ish scales; fork-cells 
short; first sub-marginal longer and narrow’er than the second posterior, their bases nearly 
level, stem of the foi’iner, not quite as long as the cell of the latter, longer; jiosterior cross¬ 
vein longer than the mid and more than its own length distant from it. 
Length : 5 mm. 
Habitat: Uplier White Nile, taken and found breeding at Taufikia. (H. King.) 
Observations: Described from a perfect female and tw’o males. It is a very marked 
species, easily told by the thoracic adornment. It is very variable in colour according to the 
light, but has a general yellowish-brown hue. The male ungues are very marked; it is 
the only mosquito 1 have seen in w’hich the hind pair are unequal, and this and the palpi 
and w’ing scale structure excludes it from any previously described genus.
