Genus Sabethes. 
249 
laterally are silvery spots (only seen at the base in this 
specimen). 
Legs with the coxae silvery, femora pale at the base, covered 
with scales which give them a steel-blue and purple hue in 
certain lights; in the mid legs the greater part of the tibiae are 
fringed with a dense mass of long deep bronzy hair-like scales 
forming a kind of paddle, which is continued on to the 
metatarsus, where the hair-like scales gradually decrease in size ; 
fore and hind legs without the paddle of scales ; in the hind legs 
the tibiae are curved upwards and the metatarsi are longer 
than the tibiae, the hind legs being long. 
Wings with the veins clothed with rather large flat scales, 
brown on the body of the wing with violet reflections on the 
costal border ; first sub-marginal cell longer and narrower than 
the second posterior cell, its stem rather more than a third of its 
length ; base of the second posterior cell much nearer the apex of 
the wing than that of the first sub-marginal cell, its stem not quite 
as long as the cell; the mid cross-vein a little nearer the apex of 
the wing than the supernumerary, and the posterior nearer the 
apex still and much the widest of the three; the third 
longitudinal passes into the basal cell and is carried through it 
as a pseudo-vein, which is nude. Halteres long, stem yellow at 
the base, fuscous above and at the knob. 
Length.—6 mm. 
Habitat .—Amazon region. 
Observations .—Described from a single $ in the British 
Museum collection in excellent condition. It might at first 
sight be mistaken for a female, for the antennae, although rather 
densely plumed, are not so densely as in other £ Culices. 
The wing venation is peculiar and characteristic. The “ paddle¬ 
like ” structures on the legs are built up of elongated scales, of 
similar type to the “upright forked scales” of the head, only 
longer. 
Wiedemann’s description of the £ is as follows :— 
“Antennae brownish, proboscis and head steel-blue, with silvery scales 
below. Thorax and abdomen steel-blue, which especially in the latter 
shades off into a greenish tint; pleurae greenish gold ; venter yellowish, 
with a silvery lustre, as also are the lateral edges of the base of the 
abdomen. Ccxae silver scaled ; legs of a fine steel-blue, in the mid leg the 
lower part of the tibia and the whole metatarsus is thickly fringed with 
long hairs, so as to form a sort of paddle with a flat surface and an egg- 
shaped outline. Front and hind legs entirely without fringes. Length, 
21 lines.”—(From Auss. Zweifliig. Ins. p. 573.)
