Description from Wied., " A. Z. I.," p. 12. — Tawny ; the thorax with 

 three deeper tinted lines ; the abdomen covered with grey hairs ; the 

 \vings with dusky spots and costa. Length 2^ lines (German). 



Coquillett, in his recent synoptic table of North American Culicidce, 

 states that " the scales of the last vein are white, marked with three 

 black spots ; palpi marked with white at the bases of the last four 

 joints," and without any spot on tlie costa, as seen in A. punctipennis. 



Professor Nuttall sent Mr. Theobald two 5 's from America m spirit, 

 which, although much damaged, show the two features mentioned by 

 Coquillett very clearly, readily distinguishing the species from the C. 

 'punctipennis of Say. 



Habitat. — United States, at the following places : District of 

 Columbia ; Georgia ; New Orleans ; Richmond, Va. Wiedemann says 

 it is very common on the Mississippi, where it is very troublesome to 

 travellers, and also gives Pennsylvania as a habitat. 



Time of capture. — April in Columbia ; June and November at New 

 Orleans.
