MOSQUITOS OR CULICIDAE OF NEW YORK STATE 333 



water, it seems to prefer pools near the upland which are mostly 

 formed by rains and by springs working down from the high- 

 lands. This form appears to hibernate as an adult and never gets 

 far away from the edge of the salt marsh. Dr Smith states that 

 the mosquitos hide wherever they can find shelter, by preference 

 in cellars, and cites the case of a factory just at the edge of a 

 marsh where thousands were found. It does not begin to appear 

 till rather late, and very little is seen of it till June. The eggs 

 are laid in boat-shaped masses similar to those of C. pipiens, 

 hatch in the same manner, and unlike other marsh forms, it 

 occurs also in the more permanent pools where other salt marsh 

 species are not found. 



Culex trivitattus Ooq. 



This is the first of a series in which the abdominal bands are 

 wanting, though in some there are light colored hairs or reflec- 

 tions which give that appearance at first sight. 



Description. This very distinct species is easily recognized by 

 the two broad yellowish thoracic stripes on each side of the 

 central dark brown one. It was described from Chester N. J., and 

 we have taken specimens in association with Anopheles 

 punctipennis at Bath-on-Hudson and also at Poughkeepsie 

 N. Y. 



Larvae of this species were taken in New Jersey in woodland 

 pools on the hills back of South Orange. Adults occur in New 

 Jersey during July, August and early September. 



Larva. It has been characterized by Dr Smith as about i/4 i^ich 

 in length with a comparatively small head one third wider than 

 long. The antennae are less than half the length of the head, 

 sparsely set with rather large spines and tipped with one long and 

 one short spine, a bristle and a stout articulated process. The 

 tuft is just before the middle and is composed of several hairs. 

 The comb consists of an irregular patch of 14 to 22 spatulate 

 scales tipped with a large spine and bearing on either side long 

 slender setae. The air tube is short, chunky, bearing a double 

 row of somewhat curved pecten, each spine usually with two or 

 three basal teeth.
