325 



Legs with femora and tibiae brown with scattered whitish

 second and third fore and mid tarsals with narrow basal pale 

 bands : banding on hind legs more pronounced ; ungues equal 

 and uniserrate. 



Wings with brown scales and some scattered pale ones ; first 

 sub-marginal cell longer and narrower than the second posterior 

 cell, its stem nearly two-thirds the length of the cell, its base 

 about level with that of the second posterior cell, stem of the 

 latter nearly as long as the cell ; posterior cross-vein a little 

 more than its own length distant from the mid. 



Length. — 6-8 mm. 



$ . " Basal clasp segment stout ; clasper slender, slightly 

 swollen near the middle, and with a long slender apical spine. 

 Claspette a slight basal lobe bearing a very long curved chitinous 

 spine and a few large setae. Harpes with the proximal portion 

 stout, and at the basal third several large internal spines ; 

 distal parts on a very long, slender, halbert-like blade, with a 

 slightly recurved acute tip. Harpogones 

 evenly rounded, terminating in a stout 

 recurved tooth and with several smaller 

 teeth. Unci approximate, rather broad, 

 apex acute. Setaceous lobes well developed, 

 with numerous large chitinous spines " 

 (Felt). 



Fore and mid ungues unequal uniser- 

 rate, hind equal and uniserrate. 



Habitat. — New England and New York 

 (E. P. Felt and L. O. Howard), Sas- 

 katchewan River, Colorado, Arizona, New 

 Mexico, and Mexico, New Jersey. 



Time of appearance.— May and June. 



Observations. — This species was at first 

 taken by Felt to be Meigen's C. cantans; it 

 can at once be told, however, by the thoracic 

 adornment and abdomen and $ genitalia 

 as pointed out by Felt. Concerning this 

 Felt writes, " The above named {cantans) 

 American species noticed by Dr. Smith and 

 the writer under the name of Culex cantans, 



Meigen, is a different species. There is considerable similarity 

 between the genitalia of our American species and the European 



Fig. 115.
