much narrower and a little longer than the second posterior cell, its 
base slightly nearer the apex of the wing, its stem nearly as long as the 
cell ; stem of the second posterior as long as the cell ; posterior cross¬ 
vein longer than the mid, not quite its own length distant from it. Hal¬ 
teres yellowish, the knob darker and clothed with grey scales. 
Length : 6 mm. 
Time of capture : April (25-th). 
Habitat: Budapest, Hungary (Kertész). 
Observations : Bedescribed from a perfect j in this collection. 
I see no reason to doubt that this is Fabricius’ species, it answers to his 
short description and is the only European species I have seen that does 
so. Culex bicolor can at once be told from it by the pipiens- like vena¬ 
tion and the simpler thorax and simple ungues. This species comes in 
the group round Culex cantans and will hawe to be removed with it to 
a new genus. 
Culex flavescens Theob. cornes very near this insect but has ban¬ 
ded tarsi.
