OeIGINAL DeSCEIPTION of CTJIEX OCEIiATUS : 



Head dark brown to black, with grey scales, white at the sides and around the eyes. 

 Thorax brown, with two dark eye-like spots at the roots of the wings. Abdomen deep 

 brown, not banded or spotted. Legs deep brown, pale basally and yentrally, un- 

 handed, with a metallic ochraceous tinge. Proboscis, palpi and antennae brown. 

 Wings with typical brown Culex scales. 



$. Head black, with scanty narrow-curved grey scales in the middle, white flat 

 ones at the sides, and white curved scales forming a border to the eyes. Antenna 

 brown, basal joint testaceous; proboscis thick, brown; palpi brown, densely scaled. 

 Thorax brown — deep brown in some lights, pale in others — 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 slightly separated; metanotum deeper brown than the scu- 

 tellum ; 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, unhanded; 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 dis- 

 tant 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 5, 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: — 



" I send you a new Culex from bromelias which I propose to call 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 Vranotaenia Lowii and Culex pleuroscriptus. For 

 the rest, it seems a close relative of C. imitator, being also very greenish in general 

 colour. The proboscis is rather long and downwardly directed, as in Vranotaenia." 



The greenish colour does not appear in the dead specimen sent. 



A fresh ^ and $ were received later somewhat larger In size (4 mm.).
