joint with a few small pale hairs; most of the apical joint 
without hairs. 
Length.—5 to 6 mm. 
Time of capture.—J une. 
Habitat.—California (Thomson) ; Lewiston, Idaho, Moscow ; 
and Cornwallis, Oregon (Aldrich). 
Observations.—This species was described by Thomson from 
California, I had seen nothing answering to it when the second 
volume went to press, but could not believe it to be the same as 
C. nigripes (Zetterstedt). It is a very marked species, the spots on 
the wings due to long scales, and the pale area at the base of 
the fork-cells being very characteristic. Thomson says nothing 
of the tarsi being banded, but these show distinct traces of dull 
testaceous basal bands in the specimens I have mounted from 
the débris saved from Professor Aldrich’s consignment. 
Professor Aldrich sends me the following note regarding its 
habits :— 
“The principal character’ given by Thomson seems to be the 
dense scales of the section just before the cross-veins, the pellucid 
spot, nearly bare, just beyond them, and their coincidence (the 
‘“incidens ” from which he drew the name), etc. The cross-veins 
are not always exactly coincident ; but in some specimens they 
are. I believe the description suits sufficiently well. I send one 
specimen from Cornwallis, Oregon, a place much nearer the 
locality of original capture than this is. I only got this Corn- 
wallis specimen lately, when I was looking through the material 
at the Oregon Agricultural College. The species is rather rare 
at Moscow ; still, it is our commonest mosquito, as we are 
blessed with an almost total absence of the family. I allowed 
a specimen of incidens to bite me not long ago, to see if there 
were any noticeable peculiarities in its habits. I had never 
been bitten by one before. It seemed to have no special 
peculiarities ; it darted off before I expected it to. The spot 
swelled but a little and gave me no great ineonvenience.”
