330 A Monograph of Culicidae. 
the length of the cell; stem of the second posterior cell nearly 
as long as the cell; the supernumerary cross-vein very small ; 
positions of the cross-veins variable, as a rule the mid and 
posterior nearly in one line and in advance of the supernumerary, 
or all three may be in one line. MHalteres dark brown; base 
paler. 
Length.—4°5 to 5 mm. 
Habitat.— British Guiana (Low) ; Para (Durham) ; Sao Paulo 
Brazil (Dr. Lutz). 
Observations.—A very variable species, which presents a great 
variety of colours in different lights and when held in different 
positions. The cross-veins vary to some extent, in some the 
posterior is much nearer the apex of the wing than the mid, in 
others it is level with the mid. This species may easily be 
mistaken for a @ of Sabethes, but the generic characters given 
on page 328 will suffice to distinguish it. 
Synonymy.—I have carefully examined the types of 2 remipes 
and 9 nitidus and am sure they are the same, the former had 
evidently been in some liquid and so the coloration of the scales 
had been altered, and the position of the cross-veins we now 
know varies in this as in other Culices. 

Genus 46. GOELDIA. nov. gen. 
Head clothed with flat scales ; mesothorax with flat spindle- 
shaped scales and larger narrow-curved ones, lanceolate in form 
before the scutellum; scutellum with flat scales ; metanotum 
with chaetae and squamae. Palpiin the ¢ nearly one-third the 
length of the proboscis, in the ? quite small; proboscis short 
and thick, not as long as the body. Wing scales like Runchomyjia, 
dense and elongated, ending asymmetrically ; the cross-vein in 
the g as in Culex; in the 9 the mid and supernumerary not 
united, the posterior as in Culex. 
This genus is founded on a ¢ specimen ; the female described 
here bears such a strong general resemblance that I have included 
it under this species. 
Tt differs from Sabethoides notably in its Culex like venation.
