116 THE MOSQUITOES OF NEW JERSEY 



full force and ready to oviposit. Of the eggs laid during May a fair 

 percentage hatch early in June and give a fair second brood of adults. 

 When these adults oviposit, an equal percentage of their eggs also de- 

 velops, and this continues through the season, the bulk of each batch 

 of eggs lying over to the next year. This keeps up an ever decreasing 

 supply as the season advances, and yet provides liberally for the enor- 

 mous spring crop in spite of the dangers attendant upon so long a 

 quiescent period under varying climatic conditions. This accounts for 

 the November larvae as probable progeny of adults which matured in 

 late September or early October. It is assumed here that the larvae that 

 hatch so late in the season do not reach maturity.

Thorax covered with yellowish scales and has usually well defined 

 broad medium stripe of brown scales, which begin almost at anterior 

 margin and is slightly constricted centrally ; also two other patches of 

 brown scales about one-third length of thorax, at base of this stripe, on 

 each side and separated by narrow line of yellow scales. Pleura very 

 dark brown, with patches of pure white scales. Legs dark brown, al-
