Culex vexans, Meigen. 
Male genitalia and female processes (after Ficaibi). 
mid ungues are unequal, the hind equal; all have a tooth, the 
mid ones are of different form to the fore. The last joint of the 
male claspers is bifid (Fig. 142). 
Length .—About 7 mm. 
Habitat .—Scandinavia (Zetterstedt) ; Russia (Gimmerthal) ; 
Austria (Schiner) ; Germany (Meigen); Holland (Van der Wulp) ; 
Britain? (Walker, Verrall). 
Observations .—This banded-legged species should be easily 
identified by the golden-scaled thorax and the toothed ungues in 
the 9 • It is recorded as British by Verrall in his list, but his 
specimens have simple ungues, and I have not been able elsewhere 
to detect its presence. Ficaibi states that Rondani’s Cnlex 
arficulatus is synonymous, having examined the specimens left by 
Rondani.
