Thorax deep chestnut-brown, with a paler median line dark 
on either side, covered with scattered golden-brown curved scales, 
and with three rows of black bristles on the mesonotum • 
scutellum ochraceous-brown, with pale spindle-shaped curved 
scales and with black border-bristles, very thick on the lateral 
lobes; metanotum bright pale brown • pleurae bright brown, 
with patches of white and yellow scales. 
Abdomen apparently much as in the £ . 
Wings clothed with brown scales, the lateral ones long and 
thin, and truncated at the free end; first sub-marginal cell 
longer but about the same width as the second posterior cell, 
its stem not quite one-third less than the length of the cell, 
longer than the stem of the second posterior cell; the base of 
the first fork-cell nearer the base of the wing than that of the 
second posterior cell; posterior cross-vein twice its length distant 
from the mid cross-vein ; fringe long, brown ; scales at the root 
of the wing purplish-black, and the basal lobe of the wing with 
the fringe of dark scales very distinct, similar to the border 
scales of the fringe. Halteres ochraceous. 
Length.— 5*5 to 6 mm. 
Time of appearance. —June (England). 
Habitat. — England (Walker, Bradley, &c.), Norway and 
Sweden (Zetterstedt) ; Austria (Schiner) ; Italy (Rondani), &c. 
Observations.— The following is Meigen’s * description of 
Ae. cinereus :—- 
“ Diese einzige Art ist melir braun als grau; Riickenschild rothlich 
behaart; Fliigel ungeflekt; Sckenkel blasser als alles Uebrige. Taster 
bei beiden Greschlechtern sehr kurz; sonst die iibrigen Kennzeichen wie 
bei Culex, 2-2£ Linie. Dies ist alles was mir Herr Justizrath Wiede¬ 
mann von dieser Art bemerkt hat, die ich weiter nicht kenne.” 
The insect described by Gimmerthal in 1845 under the name 
of Aedes rufus is probably only the same as Ae. cinereus. It is 
described as “ of a more redder tint than Ae. cinereus ; proboscis 
brownish-yellow, with the extremity brown ; palpi and antennae 
brown, the latter with the base yellow ; thorax dorsally reddish- 
brown, with a darker median and two lateral lines very in¬ 
distinct ; legs yellowish ; abdomen dark brown. Length. —5^ to 
6 mm.”
