REPORT OX MOSQUITOES. 2j^ 



The species bites readily and hard, but the records as to result? 

 differ. The collectors at Xew Brunswick make light of the bite, 

 while ]Mr. Brakeley, mosquito seasoned as he is. records the fact 

 that it raised "welts" on him at Bordentown. 



This species is no traveler, and there is every reason to believe 

 that it does not move farther from its place of birth than is 

 necessarv to find a place for oviposition. It does not fly nor- 

 mally until evening-, yet it is easily disturbed, and practically all 

 the adults taken were captured during the day. In no instance 

 was this form included in the captures made after dark. 



There is practically no record that in Xew Jersey this species 

 is at any time entitled to consideration as a pest. Its occurrence 

 even when most abundant would hardlv attract attention. 



Description of the Larva. 



The larva, plate figure 84. i. is long and slender, averaging 8 

 mm.,:^.32 of an inch in length, though specimens are sometimes 

 as long as 10 mm. In color it is brownish or grayish with the 

 head and siphon darker or blackish : young and half grown larvje 

 are grayish white. The head is broader than long, yellowish to 

 dark brown in color, with scarcely any darker shading. There 

 are four small hair tufts of five or six hairs each on the anterior 

 part of the vertex, and two long setie are slightly to the rear of 

 them ; another small tuft is at the base of each antenna. The an- 

 tenna (fig. 81, 5) is long, almost straight, dark brown in color, 

 blackish toward the base and without spines or hairs over the 

 surface. A single long seta arises from a scarcely perceptible off- 

 set at about the middle, and the apex is one long spine, twC' 

 shorter ones and a little articulated peg. The eyes are black, 

 comparatively small and are divided into two parts ; a large cres- 

 cent shaped piece and a very- small one in the concavity; they are 

 sometimes encircled by a broad white ring. The rotary mouth 

 brushes are yellow, pectinated at the tips of the more central 

 hairs. The mentum is triangular with ten or eleven teeth on each 

 side of the apex, which become larger toward the base : but there: 

 is considerable variation, chiefly in the curve of the sides, as isr 

 shown in figure 4. The mandible (fig. 84, 2) is normal wiih 

 small spines scattered near the base. The maxillary palpus (fig. 

 84. 3) is short and chimky. with a small apical tuft and large 

 basal joint. 



The thorax is broader than long, slightly angulated at the 

 sides. There are six rather short lateral tufts, two smaller on 

 the anterior maroin and two very small ones on the dorsum, near
