MOSQUITOS OR CUIJCIDAE OP NEW YORK STATE

investigations in September 1902, in the city of Albany, showed 

 that it was comparatively easy to find specimens of A n o p h e 1 e s 

 punctipennis in many of the area ways in different sections 

 of the city. It was observed that the insects were more abundant 

 in the areas where there was only a doorway and consequently 

 poor ventilation. Mosquitos evidently do not like a draft, and in 

 most places where there was a free circulation of air compara- 

 tively few were to be found. In view of this fact some relief from

mosquitos, particularly Anopheles, might be obtained by provid- 

 ing free ventilation in area ways and other sheltered places like 

 porches, so that mosquitos would be disinclined to take refuge 

 therein. As is well known, these insects may also be found in 

 outbuildings of various kinds, in fact in almost any dry place 

 where there is not too much air. They fly throughout the sum- 

 mer and we have met with specimens on snow in the middle of 

 March. 



The natural breeding places of Anopheles larvae, according to 

 Dr Howard, are in the more or less permanent pools of water 

 such as are found in the bed of an old canal in spring, in wood-
