The Mosquitoes of New Jersey

tinction between the adult house mosquito (Culex pipicns) and the 

 unhanded salt-marsh mosquito {Culex salanarius). It also fails to 

 give adequate differences between the adult of the brown salt-marsh 

 mosquito {Aedes cant at or) and the brown woods mosquito {Aedes 

 stimulans) . The same may be said of it for the larvae of mottled 

 winged anopheles (Anopheles punctipennis) and the four-spotted 

 winged anopheles {Anopheles quadrimaculatus) . It is proposed to 

 remedy these defects, which have been revealed by the practical 

 work, by submitting a comparative list of characters of the species 

 mentioned.

The practical work has shown the need of two types of keys — one 

 of which shall enable the worker to determine almost any species 

 taken in the state, and another which shall enable the observer with 

 the least possible expenditure of time and effort, to determine the 

 species that are commonly met with in the course of the practical 

 control. The first type will necessarily involve the use of micro- 

 scopic characters and is intended primarily for laboratory use, while 

 the second should involve characters which can be determined by 

 the eye, aided by an ordinary hand lens, and is intended for use in 

 the field. The former type of key will be given first and the latter 

 second.
