MOSQUITOS OR CULICIDAE OF NEW YORK STATE 309 



p'ool which 5'ielded other species freely. He adds that in New 

 Hampshire larvae occurred in every suitable pool, and after the 

 middle of July they were the most abundant Culex larvae to be 

 found, being present throughout the summer. Dr Dyar obtained 

 some eggshells, which he believed to belong to this species, from a 

 pool full 'of C. t e r r i t a n s larvae. They were on the surface of 

 the water in little boats composed of three or four eggs, each ad- 

 liering by their flat sides, the mass floating sidewise on the water. 

 They were so minute that a lens was necessary to ascertain their 

 true character. He states that the life cycle occupies about three 

 weeks, and that breeding is continuous as with C. pipiens, 

 the winter probably being passed as adults. 



Dr Smith states that this little m'osquito is rarely troublesome 

 in the early part of the summer, but sometimes late in the season 

 it seems to become possessed with a furious desire for blood. At 

 ■such times it forces its way through the netting of window screens, 

 endeavors to find openings around them, or works up between the 

 windows if they are imperfectly closed. This lasts for a short 

 time and then the mosquitos suddenly leave. It is somewhat 

 of a puzzle to account for their appearance in such numbers. This 

 form is seldom recognized in house captures, since when collected 

 in alcohol it has proved almost impossible to separate it from C. 

 pipiens.

Pupae of this well marked, beautiful species were taken in a 

 deep, cold mountain pool at Elizabethtown N. Y., June 9, adults 

 ■emerging the 10th. Larvae occurred at Karner N. Y., May 3.
