nae are six tufts of hairs, the median pair short; caudad of these 
is one pair of long setae, and directly caudad of each eye is a 
single one. The antennae [fig.1] have three or four apical bris- 
tles besides the usual small terminal joint, and a little distad of 
the middle is a single long seta. Labrum, rotatory fan and max- 
illae normal, the two dorsal spines of the latter rather longer 
than in ©. pipiens and the papillae on the mesal surface 
are more prominent. The spines of the epipharynx as in C. 
pipiens, but the lateral ones shorter than the median pair. 
The stout apical spine of the mandible [fig.2] does not project 
beyond the tip of the teeth. The labium [fig.4], is triangular 
with 19 teeth, hair on its ventral surface, and caudad of the 
transverse suture are two pairs of setae. The hypopharynx, 
shown somewhat diagrammatically in figure 6, has a*number 
of sharp teeth besides two lateral lobes with fingerlike processes 
(not shown in the figure). On the dorsal surface, along the ce- 
phalic margin of the thorax, are six or eight hair tufts, all rather 
short except the lateral ones, which are of moderate length; 
on the middle and on the posterior end of the lateral margin 
are two long tufts. Near the caudal margin are two stellate 
hairs. Each abdominal segment has, besides the long lateral 
tuft, four short dorsal tufts and a few short lateral and ventral 
hairs. The lateral comb of the eighth segment is composed of 
about eight spines arranged in one irregular row; the ninth 
segment but little longer than wide, is provided with a dorso- 
caudal tuft of 10 or 12 hairs, a ventral row of about 10 tufts, 
each tuft with four or five hairs. The blood or tracheal gills 
are comparatively short. The breathing tube is short, about 
twice as long as wide, with a lateral longitudinal row of 18 to 
20 spines, at the caudal end of which is a single hair tuft. 
Pupa. The pupa does not appear to differ from C. cantans. 
The air trumpet is widened at the top, the plane of the margin 
of the aperture makes about 45° with the longitudinal aXis.

Genus AEDES Meigen 
Small, brownish or blackish gray species closely resembling 
Culex, differing only in that both sexes have very short palpi. 
According to Van der Wulp, the palpi, though short as in the 
female of Culex, are not cylindric as in the latter genus, but 
conical or pointed, and consist of two joints only. But two 
species of adults are known from the United States.
