Doubtful Aedes. 599 
on each side in front, near the middle line, there are two small dark 
spots; there is also a large dark area on each side reaching from the 
prothoracic lobes to above the wing insertions, and extending laterally 
to the margin, and a pair of conspicuous black spots near the middle 
line on the posterior third. A row of black hairs extends from these 
spots to the posterior margin of the mesothorax. Scutellum with 
patches of white scales and hairs. Metanotum brown. Abdomen 
black, with narrow basal bands of golden scales and a row of long 
white hairs along the posterior margin of each segment; lateral areas 
of silvery scales on the hinder segments; scattered over the dark 
scaled areas are a number of lighter scales, which form an ill-defined 
stripe along the middle of the abdomen. Venter white scaled, small 
apical areas of black on the hinder segments at the sides. Legs black. 
Femora white below, through the whole length, except near the apex, 
where there is a black spot; thickly speckled with white scales above, 
especially near the base; knee spots small. Tibiae, tarsi and meta¬ 
tarsi all ventrally white scaled, a few long bristles on the joints, those 
along the tibiae longest. Ungues all equal and uniserrate. Wings, 
veins covered with broad, short, flattened scales, extremities of upper 
veins with long narrow ones as well. Upper forked cell narrow and a 
little longer than the lower. Stem about half its length. Posterior 
cross vein rather more than its own length distant from the mid cross 
vein. Halteres with pale stems and knobs. 
Length. —3*5 mm. 
cf . Proboscis black, nearly as long as palpi, with scattered yellow 
scales, especially near the base, apex slightly swollen, tip light brown. 
Both terminal joints of palpi somewhat swollen, and covered with 
many long black hairs, more numerous underneath. Ungues of fore 
and mid tarsi very nearly equal, larger with two teeth, smaller with 
one basal tooth, ungues of the hind tarsi equal and uniserrate. Geni¬ 
talia closely resembling those described and figured by Felt. (New 
York State Museum, Bulletin 97), for Culicada c.onfirmatus , Theobald. 
The spine at the apex of the terminal clasp segment is about one-fifth 
length of segment. Claspette obsolete, represented by a few weak 
setae and long hairs, one hair much longer than the others, curved at 
the tip and swollen towards base. Harpes slender, curved, base with¬ 
out hairs. Harpagones stout, very deeply infuscated with a sharp 
recurved point. Setaceous lobes with a few short stout setae. 
Length. —3'5 mm.”
