NEW MOSQUITOES FROJI THE SUDAN 
which has white scales on each side of it ; some very small w'hite scales forming a line on 
each side behind the wings ; chfetcE golden-brown, paler at the tips ; scutelluni with a 
tangled mass of long twisted white scales and long, thin, dense, golden-brown border-bristles; 
metanotum pale brown ; pleuree dark brown with patches of pale scales. 
Abdomen: brownish, covered with Hat, loose, bright ochreous scales, each segment with 
a basal wdiite median patch of larger scales, somewhat triangular in form, and an outstanding 
basal patch of long white scales on each side, broadly spatulate at their apex with very thin 
stems ; on the fifth and sixth segments the white scales are more abundant, the apical 
segment mostly ochreous but with some median white scales ; there are also some flat 
dusky scales on each side of the median white ones, and some dusky-tipped rather out¬ 
standing ones behind, especially on the apex of the fourth. 
Legs : ochreous covered with dusky-tipped and white scales, the former being ochreous 
at their base; fore femora with white scales at the apex and a narrow ring of white near it, 
tibiis with basal, median, and apical white bands; metatarsi and tarsi ochreous; mid legs 
with femora the same and the tibiie with broader white hands and more outstanding dusky- 
tipped scales ; metatarsi white at the base and in the middle, first tarsal with a basal white 
band, rest unbanded ; hind legs with the white bands still more pronounced and all the tarsi 
with basal white bands and the outstanding dusky-tipped scales more numerous than on the 
mid legs; ungues all equal, dark, thick and uniserrated. 
Wings: clothed with ochreous, dusky-white and parti-coloured scales, the last two mainly 
towards the base of the wings ; the first submarginal cell very much longer, but scarcely 
narrower than the second posterior cell, its base almost level with that of the latter, its stem 
about two-thirds the length of the cell, stem of the second posterior longer than the cell; 
posterior cross-vein longer than the mid and slightly in front of it ; the third vein close to 
the second and continued to the base of the wing as a pseudo-vein ; a distinct pseudo-vein 
continued from the upper branch of the fifth to the base of the wing, and a distinct 2 iseudo- 
vein between the fifth and sixth ending at the tiji of the fifth. The costal and first long 
vein mostly ochreous scaled, the latter with some dark scales towards the tip and some white 
and jiarti-coloured ones at the base; the ujiper branch of the second ochreous and its a^jical half, 
the rest with some scattered dark scales, the third and fourth the same, the latter with white 
and jrarti-coloured scales at the base ; the up^ier branch of the fifth densely scaled from the 
cross-vein with dark scales, from the cross-vein to the junction with the lower branch and 
with it yellow scaled, anneal half of stem yellow scaled, rest with dark jiarti-coloured and white 
scales ; sixth with large, dense, mostly dark scales on the anneal half ; fringe with eight jiale 
sjiots sejiarated by seven dark s^iots jilaced at the tijis of the fourth, fifth, and sixth veins 
and two further back ; fringe at the ajjex yellowish, a dusky 2 )atch on the costa near the tiji 
of the wing. 
Length : 7 mm. 
Habitat : Ujiper White Nile. Mr. King also found it breeding at Sangikia and took one 
at Kodok and one in Khartoum, which had p)robably been brought down in a boat. 
(Observations : Described from three females taken by Mr. King, who jiointed out their 
difference from .17. afriranns, Theob. The s^Jecies comes near it, however, and also ,17. muculiis, 
Karsch. From the former it may be told by the eight jiale fringe sjjots and hy different tibial 
banding, which is black on the basal half, white on the ajiical in africanus, whereas this s^iecies 
has three white liands ; the second ];)osterior cell also differs in having a longer stem. 
From ,1/. mucidiis it differs in having less twisted scales on the thorax, eight instead of 
seven pale fringe spots, and by the 2 >resence of a mid-tibial band, and in the unhanded 
fore tarsi.
