430 MOSQUITOES OF NORTH AMERICA 



and at the junction of the penultimate and antepenultimate, also a narrow pale band 

 on the long antepenultimate segment, which has long hairs on one side of its apex 

 for some little distance; proboscis deep brown with a narrow pale band. 



Thorax deep brown with narrow-curved rich brown scales, and three prominent 

 double rows of bright brown chsetse and others at the sides, a few paler scales be- 

 hind and over the roots of the wings; scutellum pale brown with narrow-curved pale 

 creamy scales and eight bright brown to black posterior border-bristles and some 

 smaller paler ones; metauotum deep brown. 



Abdomen deep brown, basal segment brown, with two dark patches of scales, 

 second segment with a median basal creamy spot, other segments with basal creamy 

 bands, pallid border-bristles and brown lateral ones. 



Legs deep brown, femora pale beneath, knee spot creamy white, all the tarsal seg- 

 ments except the last with small apical creamy spots or bands; fore and- mid ungues 

 unequal, both uniserrate (?), hind small equal and simple. 



Wings with short fork-cells, their bases about level, the first sub-marginal longer 

 and narrower than the second posterior, the stems nearly as long as the cells; pos- 

 terior cross-vein about twice its own length distant from the mid. 



Male genitalia with the claspers fairly broad, not much curved, a small thin ex- 

 panding lateral apical segment; lateral process of basal lobe with three large flat 

 spines, the median one broadest and curved hook-like apically, the basal one the 

 smallest, foliate plate rather short and broad; setaceous lobes large and prominent 

 with many large broad spines and two broad flattish processes beneath them; basal 

 lobes with very long chaetae. 



Length. — 5 mm. 



Habitat. — Moncague, Jamaica (Lord Walsingham). 



Time of capture. — February. 



Observations. — Described from a single ^. The genitalia mounted in balsam. It 

 comes near C. secutor and allies in general appearance, but may at once be told by 

 the apical segment of the palpi being longer than the penultimate, by the narrow 

 apical leg bands, and by the genitalia and unadorned thorax. The female is at 

 present unknown. 



We have been unable to recognize this species. 



The larva is unknown and the life history and habits are unknown. 



Island of Jamaica, West Indies. 



Culex svifuscus is described from a single male specimen and no characters 

 which we consider distinctive are mentioned ; we find it impossible to identify 

 it under the circumstances. When the male genitalia shaU have been properly 

 elucidated it may be possible to identify it ; until then we are obliged to list it as 

 unrecognizable.
