Genus Culex. 185 
with a few short brown hairs on each side, also at the apex of 
antepenultimate joint; proboscis and antennal plumes brown, 
basal joint of antennae large, pale reddish-brown. 
Thorax as in 9, but rather brighter. 
Abdomen with narrow pale bands on three of the basal 
segments, then two with large basal pale: spots, not forming 
bands, and then a mass of dull grey scales on the apical segment ; 
densely hairy. The banding in the hind legs is more distinct 
than in the ?, especially at the tibio-metatarsal joint, and there 
are also traces of banding, mostly basal in the mid legs; fore 
and mid ungues unequal, uniserrated ; hind equal and simple. 
Fork-cells small, stem of the first sub-marginal about two-thirds 
the length of the cell; stem of the second posterior cell nearly 
as long as the cel!: posterior cross-vein about two and a half 
times its own length from the mid cross-vein. Halteres pallid 
with slightly fuscous knob. 
Length.—5 mm. 
Habitat.—Kingston, Jamaica (Dr. Grabham). 
Observations.— Described from a series taken by Dr. Grabham. 
It bears a strong superficial resemblance to Culex secutor, but 
differs in having an unbanded abdomen in the 9, in the structure 
of the ¢ palpi (fig. 97), the two apical joints being much shorter 
and rather stouter than in C. secutor. 
The species are found congregated with Deinocerites cancer at 
the entrance to crab-holes by the sea-shore ; they are by no means 
as numerous as D. cancer and never fly up and attack one, so are 
probably nocturnal like D. cancer. ‘‘I have never seen C. secutor,” 
says Dr. Grabham, ‘in that locality, C. secwtor being an inland 
species.” 
CULEX CINGULATUS. Fabricius. 
(Mono. Culicid. IT., p. 5, 1901.) 
Regarding this species, Dr. Lutz writes me as follows: “TI 
find now that they (cingulatus) always have the peculiar form of 
the first abdominal segment you describe in C. cingulatus, though 
sometimes it is not easily seen unless searched for, and this 
striking character separates them at once from C. fatigans. At 
first the two species may not seem very much alike, as C. cingulatus 
is somewhat smaller and darker, but the two species are both 
very variable and very much mixed up together, also similar in 
habit, and in somewhat worn specimens confusion is quite easy. 
C. cingulatus is by no means rare near habitations, and I have
