170 THE MOSQUITOES OF NEW JERSEY 



HABITS OF THE ADULT 



It is not definitely known how the insect hibernates, though the indi- 

 cation is that it does so in the egg stage. It is certain that none of the 

 collections of hibernating adults thus far made has produced even a 

 single example of this species.

 B. Smith.) 



Among the house collections apicalis occurs rarely. In reality, there 

 were thirteen examples out of 318 that seemed referable to this species 

 in the 1902 collection. The collections made in 1903 show an even 

 smaller percentage in a much greater number of examples, all taken late 

 in the season. There is some doubt also about the egg laying habits 

 of the insect, but it seems certain that it makes small boats which prob- 

 ably disintegrate rapidly, allowing the individual eggs to sink to the 

 bottom.
