Genus Culex . 
and metatarsi with black bristles ; hind metatarsus about two- 
thirds the length of the hind tibia ; in certain lights the legs 
have a pale bronzy sheen. 
Wings with the veins with long lateral brown scales, trun¬ 
cated at the apex ; those along the costa and base of the first 
long vein black ; first sub-marginal cell longer and narrower than 
the second posterior cell, its base nearer the base of the wing 
than that of the second posterior, its stem about equal to half the 
length of the cell ; stem of the second posterior nearly equal to 
the length of the cell; posterior cross-vein rather more than twice 
its own length distant from the mid cross-vein; fringe dark 
brown; basal lobe of wing with a fringe of flat black scales, and 
near the base of the first long vein are a few bristles. 
Halteres with a pale yellowish-white stem and the knob 
covered with small flat white scales. 
Length .—6*5 mm. 
Time of capture. —July, in England. 
Habitat. —England (Yerrail and Stephens), Austria (Meigen), 
and Russia (Gimmerthal). 
Observations .-—What I take to be this species is very distinct 
in appearance, the thoracic ornamentation being very character¬ 
istic, but like C. ornatus. Rondani’s G. albopunctatus, found in 
Italy, is said to be the same species ; but I fancy it is quite 
distinct. 
G. lateralis comes very near Walker’s G. obturbans and Giles’s 
C. pulcriv enter, but differs in thoracic ornamentation, &c. Between 
it and G. ornatus, Meigen, there is not much difference ; the latter 
has basal white bands to the segments, whereas G. lateralis has 
only basal white spots. 
73. Culex uncus, n. sp. 
Thorax chestnut-brown, with tawny and black scales and 
a few lateral pale ones. Abdomen brownish-black, with basal 
white patches, which extend in some cases nearly across the 
segments, to form incomplete bands. Clypeus very blunt and 
broad. Legs dark brown, except the ventral surfaces of the 
femora, which are pallid. 
9 . Head clothed with curved scales in the middle, a small 
patch of creamy scales at the sides, and a narrow pale border 
round the eyes, with three or four short black bristles projecting 
forwards, and with two or three longish ones projecting from
