Genus Culex. 431 



nearly twice its own length distant from the mid ; halteres with 

 grey stem and fuscous knob. 



Length. — 4 mm. 



Habitat. — Lualas ; Lado (Sheffield Neave). 



Time of capture. — -January (28. 1. 05), and February. 



Observations. — Described from three females all in perfect 

 condition, one gorged with blood and quite black. 



The species comes, near Culex guiarti, Blan chard, but can at 

 once be told by the different wing venation, pale grey pleurae and 

 from the next allied species by the hind metatarsi and tibiae 

 being the same length. 



One specimen shows the stem of the first submarginal cell 

 slightly longer than the rest. 



The scales on the basal lobe of the antennae I have not 

 noticed before in any true culex. 



The species appears to be common and may easily be confused 

 with C. guiarti and the other allied species described here.
