182 THE MOSQUITOES OF NEW JERSEY 



short ones, outer part of base with patch of fine hair-like spines. Max- 

 illary palpus has moderate tuft of long hair on apex and number of 

 pectinated hairs on base. Basal joint very small with four spines at 

 apex. 



Thorax angulated slightly, transversely oblong, with numerous 

 hairs arising from tubercles at angles of sides ; anterior margin has 

 some very long stout hairs extending beyond head, most central ones 

 being grouped at base, but issuing from separate tubercles ; more lat- 

 eral ones separated at the base, each with one or two hairs. 



Abdominal segments from one to seven subquadrate, anterior two 

 with lateral tufts of four or five hairs each, following four with tufts 

 of two hairs ; those of the seventh and eighth very much reduced. 

 Scales composing combs of eighth segment greatly elongated from 

 seventeen to twenty-six in number, arranged in single row. Anal siphon 

 five or six times as long as broad, tapering slightly toward apex, dark 

 brown, black tipped, with double row of very small, simple or one- 

 toothed spines, eleven to fifteen in each row. On ventral border row of 

 about thirteen small, fine-haired tufts extending entire length. Ninth 

 segment considerably longer than wide, with ten or twelve tufts on 

 dorsal part of apical margin also short, each with one very long hair. 

 Anal gills as long, or nearly as long, as ninth segment. 



HABITS OF THE EARLY STAGES 



From time to time a collector had mentioned a "bronze wriggler" 

 which occurred in woodland springs, very late in the season, specimens 

 being taken up to the middle of November; but no attempt was made 

 to breed it until, after a specimen had been sent to Dr. Dyar, who pro- 

 nounced it melanurus, a species originally taken by him in New Hamp- 

 shire. In the winter of 1902-1903 Mr. Brakeley determined to test his 

 belief that these larvae hibernated in that condition and found that 

 there were several places on his land where they could be found other 

 than the springs, nearly or quite all of which had a greater or smaller 

 supply. The chief point of interest was a stretch of swampy bog land 

 that had been burnt over early in 1902, the fire eating through the 

 moss in places and leaving a mass of irregular holes, varying in size 

 and depth. Some of these were partly closed by vegetation covering 

 in from the edges and making an overhang. The ground was springy 

 and there were numerous springs round the edges, so that the water 

 was always cold and usually clear, but with a flocculent sediment 

 which was readily stirred up.
