Genus Culex. 293 
showing three more or less distinct median dark parallel lines 
and a dark eye-like patch on each side over the base of the 
wings with a line of slightly paler scales surrounding their inner 
edge, covered with very small narrow hair-like curved brown 
scales ; scutellum paler brown, with a median dark crescentic 
patch and dark laterally, median lobe with six bristles, in two 
groups shghtly separated ; metanotum deeper brown than the 
scutellum ; pleurae pallid. 
Abdomen deep brown to almost black, with violet: reflections ; 
last segment smaller than the rest, apex acuminate, apparently 
no posterior border-bristles, but lateral ones, and some on the 
last segment ; venter pallid. 
Legs deep brown, unbanded ; the coxae and venter of femora 
ochraceous, and, to some extent, the venter of the tibiae ; ungues 
small, equal and simple. 
Wings small, densely brown scaled, and with very pronounced 
veins, the median vein scales large in proportion to the size of 
the wing, the lateral long and thin ; fork-cells short, the first sub- 
marginal longer, but no narrower 
than the second posterior, its base 
slightly nearer the base of the wing 
than that of the second posterior, 
its stem half the length of the 
cell ; stem of the second posterior 
more than two-thirds the length of 
the cell; posterior cross-vein rather more than twice its own 
length distant from the mid cross-vein ; costal border with dense 
spine-like scales ; fringe brown, dense and long. Halteres with 
pale brown stem and fuscous knob. 
Length.—2 to 3 mm. 
Habitat.—Sao Paulo, Brazil (Dr. Lutz). 
Observations.— Described from a single 9? , practically perfect. 
It is one of the smallest Culex I have seen, and has particularly 
dense scaled wings. The thoracic ornamentation can only be 
seen in certain lights, when it is very prominent, in other lights 
the thorax looks almost unadorned. 
Regarding this species, which was pointed out as new by 
Dr. Lutz, and the name suggested by him, he writes as follows :— 
“T send you a new Culex from bromelias which I propose to 
eall ocellatus. It has a black spot at the root of the wing, another 
on the metanotum and a black line on the side; characters 
resembling Uranotaenia Lowit and Culex pleuroscriptus. Wor the
