180 THE MOSQUITOES OF NEW JERSEY 



Thorax evenly brown, covered with very short spiny hair. Legs 

 dark brown, with under side of femora yellowish white. In male inner 

 claw of anterior tarsal joint long, with median and basal tooth; outer 

 claw smaller, has only single tooth near base. Claws of middle tarsal 

 joints same, except a little longer and more slender; claws of the hind 

 tarsal joints simple. In female claws are alike on all feet, same as 

 posterior ones of male. 



Abdomen dark brown, very narrowly banded with yellow white at 

 base of segments. Sometimes bands obsolete; sometimes, on the more 

 anterior segments, divided in the center by the brown. Beneath color 

 is ashen gray in females, but darker in males. 



HABITS OF THE ADULT 



Practically nothing is known of the habits of the adult; but it is 

 reasonably certain that the species does not bite, hence cannot be 

 ranked as pestiferous. 



In general appearance it resembles an undersized, dark pipiens and 

 would not be readily distinguishable from it, if the two flew together. 



DESCRIPTION OF THE LARVA 



When full grown measures, exclusive of anal siphon, 7—8.5 mm. 

 (.28-.34* inch) long, delicate build; pale yellowish or bronzed grayish. 

 Head yellowish brown ; siphon dark brown, black toward tip, render- 

 ing it rather conspicuous in contrast with paler color of larva. Head 

 large, almost size of thorax, not quite three-fourths as long as broad, 

 rounded in front and full at sides, with decided offset between vertex 

 and genae for reception of antennae. Vertex immaculate, with two 

 small hair tufts near center ; one long hair slightly in advance of each ; 

 another tuft is at base of each antenna. Antennae long and slender, 

 narrower beyond tuft, curved inwardly, uniformly grayish brown, with 

 surface covered with long spines. Tuft large, composed of many long 

 hairs and arises from offset at outer fourth ; apex with three very long 

 bristle-like hairs, one short bristle and very small terminal joint, all 

 articulated. Eyes reniform, not large, situated on sides where head 

 is widest ; sometimes e^^e divided into two parts, one large anterior 

 body and little one at center, posteriorly. Hairs composing rotary 

 mouth brushes long and silky, not pectinated. Very little variation in 

 mentum, usually two and one-half times as broad as long. From seven 

 to nine large teeth on each side of apex (eight being average), which 

 have tendency to point toward center. Mandible triangular, rounded 

 at corners, dorsal part with three long, curved spines and number of
