own length distant from it ; the linear scales on the apical areas 

 of the veins verv dense. 



Length. — 5 mm. 



Time of capture. — October. 



Habitat. — Supenaam, Essequibo (?). British Guiana (Dr. 

 Rowland). 



Observations. — Described from a perfect female. It resembles 

 Culex scholasticiis, Theobald, but can at once be told by the 

 exceptionally long first sub-marginal cell, with its very short 

 stem, and by the more elongated form of the wings. It is also 

 closely related to the following species, from which it can also be 

 told by the very long first fork-cell.
