596 A Monograph of Culicidae. 



base of the wing, its stem less than one-third the length of the 

 cell, stem of the second posterior two-thirds the length of the cell ; 

 mid cross-vein slightly in front of the supernumerary, the posterior 

 much longer than the mid, in a line with it. 



Length. — 5*8 mm. 



Habitat. — Sao Paulo and Rio de Janeiro, Brazil (Dr. Lutz). 



Time of capture, — November. 



Observations. — Described from two perfect J ? s given by Dr. 

 Lutz. It shows most varied and beautiful colouring of brilliant 

 metallic hues, almost defying description owing to the varied play 

 of colours. The mid legs only being paddled will, however, at 

 once separate it from all but S. remijpes. The thoracic blue and 

 green colours instead of coppery-red and green and the abdomen 

 having golden lateral spots instead of white in the ? also at once 

 render its identification an easy matter.

One new species only has been described in this genus, viz., 

 W. greenii, Theobald, from Ceylon. Dr. Lutz refers to another, 

 however, in his synoptic table as W. leucostigma.
