37. Culex annulipes. Meigen (1830). 
(Syst. Beschr. yi. 241, 15, Meigen; Dipt. 8cand. ix. 34G2,10, Zett.; Fn. Auslr. 
ii. 627, Schiner; Dipt. Neer. viii. 346, Van tier Wulp; Ins. Brit. Dipt. 
iii. Walker.) 
“ Proboscis rather yellowish, darker at base and apex : palpi 
of d yellowish, with the apices of each joint darker, with brown 
specks and tomentum ; in the 9 very brown ; nape and thorax of 
the 9 rather brownish, ferruginous, with two faint darker 
converging lines and paler scales at the margin : pleurae speckled 
whitish; abdomen dorsally uniformly light yellow : wings with 
the veins ferruginous ; the fork-cells with their branches longer 
o J o 
than their stems, the hinder stem the shorter : legs generally 
yellowish, femora yellow, speckled black above ; tibiae and tarsi 
light yellow, the joints of the latter nearly black at the apex, 
with three or four white basal bands, progressively narrower in 
the lower joints, the last joint sometimes quite black.' 
Length. —10 to 12 mm. 
Habitat .—Austria (Schiner); Germany (Meigen) ; Russia 
(Gimmerthal); Sweden (Zetterstedt); Holland (V. d. Wulp); 
England (Walker and Verrall). 
Observations. —I have been unable to find a specimen of this 
species in England, but it is recorded by Verrall in his list of 
British Diptera. 
Eicalbi gives a few’ additional details from some 9 s received 
by him from Germany. Meigen and Schiner both state that it 
is near C. cantans, but is more ferruginous. 
Ficalbi's description of the abdomen as being uniformly light 
yellow should at once make its identity an easy matter. 
38. Culex sylvestris. n. sp. 
(Fig. 138, PI. XXXV.) 
Thorax deep brown, with thin golden scales, pale in front 
of the scutellum. Abdomen with dusky brown to black scales, 
wfith basal bands of pure w 7 hite, bent in in the middle, last 
two segments with apical w’hite bands as well. Legs brown 
and black, femora pale beneath and at the base, the metatarsi 
and some or all of the tarsi wfith narrow pale basal bands. Fore 
and mid ungues of the 9 equal, uniserrated; hind equal, simple.
