Genus Culex. 429 



Wings clothed with typical brown Culex scales; fork-cells 

 rather short ; first sub-marginal cell very slightly longer, but 

 narrower than the second posterior cell, its stem about as long as 

 the cell, its base about level with the base of the second 

 posterior cell, if anything slightly nearer the apex \ stem of the 

 second posterior cell not quite as long as the cell ; posterior cross- 

 vein very short, about twice its own length distant from the mid 

 cross- vein ; a pale spot at the base of the wing ; hal teres 

 testaceous. 



Length — 4 to 4*5 mm. 



Habitat.— Kingston, Jamaica (Dr. Grabham). 



Time of capture. — August. 



Observations. — described from a series of $ 's taken by 

 Dr. Grabham in 1903. They are very distinct, thick-set, small 

 mosquitoes, easily told by the thoracic adornment ; the two dark 

 spots on the front of the mesothorax are very characteristic. 



It, to some extent, resembles Culex secutor, Theobald and 

 C. janitor, Theobald, but the unhanded legs at once separate them, 

 as well as their much stouter build. 



There is some variation in venation ; a few specimens show 

 the base of the first sub-marginal cell slightly the nearest to the 

 apex of the wing and the posterior cross-vein is as long as the 

 mid cross-vein and about its own length distant from it. In 

 others the basal abdominal banding is very faint. In one there 

 is a trace of an additional basal abdominal band. 



When alive Dr. Grabham has noticed that they can at once 

 be identified by the habit of carrying their hind legs twisted 

 right forward over their head, when settled, after the manner of 

 the Wyeomyias and Dendromyias. The male and the life-history 

 are at present unknown. 



Culex neavei. Theobald (1906). 



Sec. Kept. Gord. Coll. WeU. Labs., p. 76 (1906). 



Head brown with a grey patch on each side ; proboscis deep 

 brown unbanded. Thorax adorned with rich golden-brown 

 scales. Abdomen brown, unbanded, but the segments with few 

 scales at their base giving a quasi-banded appearance, all the 

 segments with basal lateral white spots. Legs brown, unbanded, 

 the femora pale grey ventrally and at the base ; the hind 

 first tarsals and tibiae of equal length ; wings of typical Culex 

 form.
