A Monograph of Culicidae . 
In many specimens we get the laterally expanded basal 
white bands broken in the middle, the insect appearing to have 
basal lateral white spots only. In this form and when the band 
is very faint they answer very closely to Meigen’s C. stricticus. 
Lt.-Col. Giles gives additional notes on C. stricticus , after examin¬ 
ing the types in the Jardin des Plantes, which also agree closely 
with the variety detritus. 
Specimens labelled C. stricticus exist in the old collection in 
the British Museum, but they certainly are not at all related to 
it. C. stricticus , Meigen (1838), may possibly stand as a synonym 
of C. nemcrosus, but probably forms a small variety, being only 
Culex nemorosus, var. detritus, Hal. 
d ungues. 
4 mm. in length. As I have not seen the type, however, and 
as it is much smaller than any C. nemorosus I have yet seen, I 
append it only a doubtful synonym. 
After examining a number of Culex provocans, Walker, from 
Canada, I find it to be the same as Meigen’s species treated here. 
It also bears, like var. detritus , a superficial resemblance to 
C. pipiens, but the venation is very different. 
In what I have taken to be C. nemorosus in Europe and 
C. provocans in America the supernumerary and mid cross-veins 
make an open angle, but in the closely related C. consobrinus 
they do not meet. Coquillett makes C. provocans synonymous 
with C. stimulans, Walker, but it is quite distinct from that 
banded-legged form.
