AQUATIC INSECTS IN NEW YORK STATE 427 
Culex, the plane of the margin being about at right angles 
with the long axis of the tube. On the dorsum of thorax is a 
pair of short forked hairs just caudad of the trumpet; on the 
metathorax is a transverse row of slender setae, and caudad 
of the base of the posterior margin of the wing are five or six 
rather long setae. The two stellate hairs on the first abdominal 
segment are very conspicuous. The rest of the segments each 
with a few subdorsal hairs; on the posterior end of the lateral 
margin of segments 4, 5 and 6 is a single long one, and on 7 and 8 
a conspicuous fan of hairs [fig.5|. The swimming paddles are 
rather small and with cilia on posterior margin. The thorax in 
mature specimens is dark brown, the abdomen paler.

Genus uRANoTAENIA Arribalzaga 
This genus possesses in most respects the same characteristics 
as Culex and Aedes; it differs from Culex however in having 
short palpi in both sexes, agreeing in this with Aedes, but diifers 
from the latter in having violet blue scales on the thorax. The 
palpi of both sexes are two jointed, the basal joint globular, 
nearly as large as the basal joint of the antennae, the apical 
joint small, conical and pointed; differing thus from the cylindric 
palpi of the female Culex.

“Wings unspotted; abdomen dorsally brownish, thorax 
tawny brown with a median dorsal, and three lines on the 
- pleurae, metallic blue; tarsi brownish, unbanded.” Description 
of Osten Sacken. 1868. 2:47. “ Fuscous, the frons, a median 
thoracic line and stripes on pleurae metallic blue; bases of coxae 
and femora pale; apexes of the femora and tibiae snowy. Front 
blackish, with a metallic blue reflection along the eyes, spe- 
cially in the middle. Antennae blackish, scapus tawny; those 
of the male apparently 15 jointed (15 plus two), flagellum with 
12 beautifully bearded joints; a 13th elongated, linear joint has 
some scattered hairs, but no beard like the preceding ones. 
Proboscis long, reaching in the male if bent backward, to about 
the middle of the abdomen; rather conspicuously incrassated 
at the tip; perhaps still longer in the female (abdomen of my 
female injured); thorax brownish, tawny, darker above, paler 
on the pleurae; a metallic blue longitudinal line along the middle 
of the thorax reaches the scutellum; three similar marks on the 
pleurae, the upper of which is in the shape of a short line run-
