June, 1929] MOSQIHTOES OF NEW HAMPSHIRE 21 



Eggs laid in rafts on the surface of the water. As far as known, but 

 one generation occurs. Females not troublesome biters. Rare. 



Monadnock, May 11 (A. H. Thayer); White Mountains (H. K. Mor- 

 rison.) 



Genus Mansonia 



Mansonia perturbans (Walker). Irritating mosquito 

 Breeds in permanent grassy swamps or margins of ponds. Eggs laid 

 in rafts on the surface of the water. Winter spent as a half-grown larva. 

 One generation. The larvae do not come to the surface to breathe, but 

 attach themselves to the roots of sedges by means of their pointed air- 

 tubes and obtain air from the plant tissues. The pupae attach and 

 breathe in a similar manner by means of their breathing-trumpets. The 

 females will fly several miles, are severe biters and enter houses freely.

Genus Culex 



Winters as adult females. Eggs laid in rafts on the surface of the 

 water. Several generations each year. The larvae have long air-tubes. 

 Culex territans Walker. White-dotted mosquito. 



Breeds in dirty ground pools, stagnant ditches and artificial recepta- 

 cles as water barrels. A semi-domesticated species often breeding around 

 houses and entering freely. An annoying biter. 



Center Harbor, Aug. 22 (H.G.D.) ; Johnson reports it from the Mt. 

 Monadnock region. 



Culex pipiens Linn. House mosquito. 



This is a domesticated species rarely found far from human habita- 

 tions, and often the only species breeding in cities. Breeds primarily in 

 water in artificial receptacles such as barrels, buckets, tin cans and bot- 

 tles, also in sewer catch-basins, obsti-ucted roof gutters and sometimes 

 in dirty ditches and ground pools. The larvae will live in foul or pol- 

 luted water. Enters houses freely and is a troublesome biter at night. 

 Often rare in rural districts and villages.
