THE INSECTS OF NEW JERSEY. 719 



A. signifer Coq. Larvae have been taken at Chester, IX, 5, XI, 17, Riv- 

 ertou IX, 8, Delair IX, 20, Lahaway IX. This species breeds normally 

 in tree holes, though occasionally it resorts to barrels or old tubs; 

 it has only been taken in late fall. 



A. atropalpus Coq. This species breeds only in rock-pools. It has been 

 taken in Maine and in Maryland, but not yet in New Jersey. It is 

 almost certain that it occurs along the shores of the Delaware River 

 near the Water Gap. 



A. canadensis Theob. Throughout the State. The commonest of our 

 woodland pool mosquitoes, larvas hatching from over-wintering eggs 

 before the ice is permanently off the surface. There is one heavy 

 regular spring brood, but larvae may be found in greater or less 

 abundance throughout the season. Bites readily enough in the 

 woods, but does not follow into the open and never enters houses. 



A. dyari Coq. Culver's Lake V, 29, tared from pupa. 



A. triseriatus Say. Taken in many localities in the northern half of the 

 State; but undoubtedly occurs everywhere in it. Breeds normally 

 in tree holes; but also occasionally in pails or other wooden recep- 

 tacles. Larvae have been found as early as April 18 (Paterson), as 

 late as November 17 (Chester), and at all periods throughout the 

 summer. 



A. serratus Theob. Breeds in low, swampy woodland, and sometimes in 

 mountain pools. Adults have been taken at Great Piece Meadow 

 IX, 17, New Brunswick VI, 23, X, 5, Cape May IX, 21. Larvae have 

 been found at Great Piece Meadow IX, 9, Orange Mts. VIII, 6, New 

 Brunswick VII, 29. VIII, 13. IX, 3. 30. 



A. dupreei Coq. Occurs in the same pools with the preceding and at the 

 same time. It is a small, rare species; the adult does not bite humans 

 and the larva is a bottom feeder that gets its supply of oxygen from 

 the water itself. 



A. abserratus Felt. Larvae have been taken in the Orange Mts. IV, 20, 

 and at New Brunswick IV, IG to V, 2. It is probably the earliest of 

 the spring species to mature, the larvae rarely extending into May, 

 and not appearing again later in the season. Breeds in low, swampy 

 woodlands and in mountain pools. 



A. trivittatus Coq. Quite generally distributed throughout the State; 

 hardly common, but more abundant in the northern half. Larvae 

 from V, 8 to VIII, 12; adults from VII, 2 to IX, 3. Breed in un- 

 sheltered pools, associated with "sylvestris." 



A. pretans Gross. Larvae in the Great Piece Meadow IV, 19-V, 10; adults, 

 Chester VII, 30, IX, 10, Great Piece Meadow IX, 13, Lake Hopatcong 

 VII, 21, Trenton VII, 18. Mr. Grossbeck writes: "Taken rarely except 

 in the Great Piece Meadows, where, in some years, it occurs in count- 

 less millions." 



A. inconspicuous Gross. Larvae taken on Garret Mt., Paterson, IX, 29, 

 which produced adults X, 4, 5. They were found in a rock pool, and 

 have not been found since.
