94 THE MOSQUITOES OF NEW JERSEY 



which appears as tooth. Small claw very short, and simple. Claws of 

 middle and posterior tarsal joints equal and simple, latter little smaller 

 than the median. In female claws equal and simple on all feet. Wings 

 hyaline, with veins covered with black and yellow scales in patches as 

 follows : costa, basal two thirds and central part of outer third black, 

 each end of outer third yellow ; sub-costa, black ; radius one, basal two- 

 thirds and central part of outer third black, each end of outer third 

 yellow ; radius two, black at basal three-fourths, then yellow to fork, 

 remainder black except small yellow portion of wing margin ; radius 

 three, black, sometimes with yellow portion near wing margin ; radius 

 four and five black, except for few yellow scales near wing margin ; 

 media one and two, black, divided twice by yellow before fork and again 

 at central third after fork ; media three, black with central yellow por- 

 tion near base. Maculation of wing veins runs generally as given above, 

 but more or less variable ; yellow portions sometimes much larger or re- 

 duced ; yellow divisions on media one and two before the fork connecting 

 in one broad patch. 



Abdomen dark brown with yellowish brown hairs evenly scattered 

 over entire surface ; beneath also dark brown, paler at base of segments. 



HABITS OF THE ADULT 



This species occurs throughout state and is really our common form. 

 On the whole much more abundant south of red shale line and dominant 

 species throughout most of South Jersey. Nothing at all peculiar or 

 unique in its habits. Readily recognized by distinctly mottled wings ; 

 large size, largest species in state except for Psorophora. 



[This mosquito passes winter in adult form in such sheltered places 

 as it can find. Winter mortality usually high. Definitely shown that 

 mosquito can transmit malaria; rarely does so in any large way.] 



DESCRIPTION OF THE LARVA 



Structurally larvae differ greatly from those of Culex, possessing 

 very complex respiratory apparatus, adapted to surface feeding habit. 

 Full grown larvae 6-6.5 mm. (.24-.26 inch) to end of ninth segment. 

 Body of young larvae, exclusive of head and chitinized parts of respira- 

 tory tube, pale yellowish white, almost transparent, except broad ali- 

 mentary tract, which is dark gray or black ; large larvae usually gray, 

 or brownish gray, but often clear pale green ; only in latter case is ali- 

 mentary tract visible. Longitudinal stripe, broken by small dorsal 

 plates, runs down center of dorsum, and usually white in color, rarely 

 bright pink, narrow, though widened at each of segmental sutures.
