Genus Culex. 147 
base; last two joints nearly equal; proboscis deep brown, 
slightly pale at the apex. 
Thorax much as in the 9 j niid lobe of the scutellum with 
seven border-bristles. 
Abdomen narrow, with distinct pale ochraceous basal bands, 
which on the last two segments spread down laterally; with 
long dense golden-brown hairs. 
Legs as in the female, fore ungues unequal, uniserrated, the 
larger slightly curved; in the mid legs the larger is rather more 
curved; hind ungues small, equal and simple. 
Length. —4 * 5 to 4 • 8 mm. 
Habitat .—Hong Kong (Dr. Rees). 
Time of capture .—October. 
Observations .—Described from two $’s and two $’s sent me 
by Dr. Rees, in his Hong Kong collection. At first sight they 
might be mistaken for Culex pipiens, but the one fair specimen 
shows the thorax to be very differently ornamented, there being 
a median dark-scaled line of considerable breadth, and the scales 
in front of the wings are dense and hair-like, quite different from 
those at the sides in front; the stem of the first sub-marginal 
cell is also relatively much longer, and more nearly approaches 
C. fatigans in venation, but it is quite distinct in thoracic orna¬ 
mentation. One specimen shows the bases of the abdominal 
segments to be nearly completely banded with pale ochraceous 
scales. The one from which this description is drawn has the 
abdomen partly denuded, and may possibly have been the same. 
It also resembles C. sericeus, mihi, from the same locality, but 
again the thoracic ornamentation should readily separate them, 
and the stem of the first fork-cell is much shorter in this species 
than in C. sericeus.

Thorax dark rich brown, with narrow curved dusky-bronze 
scales, with a narrow median dusky line and a linear dusky 
patch on each side in front. Abdomen dark brown, with dull 
ochraceous basal bands, often indistinct. Legs brown, the 
femora ochraceous, mottled with brown scales. Head dark
