REPORT ON MOSQUITOES. 265 



CUIvEX CANADENSIS, THEOB. 



TJie Woodland pool Mosquito. 



The distinctive characters of this species are the white banded 

 tarsi, the last joints of the hind pair being entirely white and the 

 joints being white at both base and tip; the black, unhanded beak, 

 the brown, unhanded thorax, unspotted wings and the medium or 

 rather large size. This combination of characters holds equally 

 for both sexes and separates canadensis from all other New Jer- 

 sey mosquitoes. 



Description of the Adidt. 



This is a mosquito of medium size and not very robust in. ap- 

 pearance. The body, exclusive of the beak, is about 6 mm., or 

 one-quarter of an inch in length ; the beak is about one-third the 

 length of the body and the wings expand 10 mm., or about three- 

 eighths of an inch. The head is brown, largely taken up by the 

 black eyes; the beak is black or blackish, without marks or rings; 

 the palpi in the female (fig. 81, 3) short, blackish, four- jointed, 

 set with rather stout and moderately long hair, the terminal joint 

 very small, yet not retracted nor shrunken. In the male the palpi 

 (figs. 41, 2) are as long as the beak, black, the basal joint with 

 two white bands, the second and third joint also incompletely 

 banded at base. Toward the tip the palpi have dense, fan-shaped 

 tufts of hair inwardly. 



The antenna of the male is plumose, silky brown in color, not 

 much more than half as long as the palpi, the terminal two 

 joints (fig. 5, i), long and slender, the central and basal joints 

 (fig. 5, 2) cup-shaped, with a circle of very long silky hair. In 

 the female the antenna (fig. 5, 3) is longer, much more slender, 

 the individual joints (fig. 5, 4) set with shorter and longer stiff 

 hair and with a circle of long, moderately stout hair at the base of 

 each joint. 



The thorax is evenly brown without obvious lines or spiny 

 clothing. The legs are black or blackish, the femora yellowish 

 on the inside, a white dot at the knee. Tibiae set with small spines 

 and some longer whitish hair, white at the tips. All the tarsi are 

 white ringed, the base and tip of each joint being white. In the 

 anterior tarsi there is only one well marked ring in the female, the 

 others being much reduced, in the male all the rings are almost 

 obsolete. The mid tarsi have all the rings obvious, but much re- 

 duced toward tip. The posterior tarsi have all the joints broadly
