A KEY TO THE BITING MOSQUITOES 
OF NEW ENGLAND* 
By George S. Tulloch 
A study of the infestation and distribution of biting 
mosquitoes in Massachusetts was made during the spring 
and summer of 1930. To facilitate the identification of the 
mosquitoes found, the following key 1 was constructed; it 
being taken from Dyar 2 and Matheson 3 and modified to 
include those species known to occur to New England. It 
is accompanied by a plate illustrating many of the taxo- 
nomic characters used in identification and by a few notes 
concerning mosquitoes considered to be of interest.
