Genus Culex.

It is also evidently closely related to, but clearly distinct 
from, Skuse’s C. occidentalism which has the first joint of the scapus 
ochraceous, the eyes bordered behind by a narrow line of golden- 
yellow scales, and the first sub-marginal cell considerably longer 
and narrower than the second posterior cell. 
The species with which it is most likely to be confused, 
however, is C. vigilax, Skuse, but an examination of the thoracic 
scales will at once separate it, the scales being narrow curved 
ones, not flat and spindle-shaped as in Skuse’s species. 
Some of the specimens sent by Dr. Bancroft were bred from 
salt water.

(Brit. Mus. List, Dipt. p. 4.) 
Thorax brown, densely clothed with golden-brown curved 
scales. Abdomen brown, with basal bands of yellowish-white 
scales, and also traces on the apical borders; the basal bands 
spread out laterally, last two segments with many pale scales. 
Legs brown, with an ochraceous tinge, with basal pale bands to 
the tarsi, quite white in the hind legs. 
9 . Head dark brown, with dull golden curved scales, a few 
dark upright forked ones and a few black bristles in front, yellower 
at the sides; antennae dark brown, with basal joint and base of 
second joint bright testaceous, a few pale scales on the basal 
joint, pubescence white ; palpi testaceous, with dusky scales and 
black bristles; the bright testaceous colour shows distinctly, 
except at the apex, where the scales are denser, with two narrow 
bands of white scales towmrds the base in one specimen; pro¬ 
boscis dark brown ; clypeus deep purplish-brown ; eyes deep) purple 
and silver. 
Thorax brown, densely covered with golden-brown curved 
scales, with two rows of black bristles on the mesonotuin and 
black bristles over the wings ; scutellum brown, with pale curved 
scales and bright golden bristles on the posterior border ; meta- 
notum chestnut-brown; pleurae chestnut-brown, with one large 
patch of pale scales. 
Abdomen covered with deep dusky-brown scales with purplish 
reflections, and with basal bands of creamy-white scales, the

C. cantans , Meigen.
