same clay. These were the last emergences of this species, though 

 hundreds of canadensis issued in the few days following. Adult 

 captures were made May 25th, and seven more or less worn specimens 

 were taken either upon the clothing or in the act of biting. A single 

 female was sent in by Mr. Brakeley, who bred it May 2d, out of a 

 lot of mostly canadensis. 



Culex dupreei Coq. (Dupree's Mosquito). — The species occur with 

 C. serraius, and like it, has not been taken during the past season. 

 None of the pools where it occurred previously contained water at its 

 proper time. 



Culex tnviitatus Coq. (The Three-Striped Mosquito). — Larvae of 

 this species, full grown, were taken at Madison, Morris county, May 

 8th, and again in the cedar swamps near Manahawken, June 15th. 

 Both times they were associated with C. sylvestris. The early appear- 

 ance of large larvae with sylvestris of the same size would Indicate that 

 eggs are laid in fall and that the winter is passed in that stage. Adult 

 captures in a very fresh condition were sent in from Madison Sep- 

 tember 1st. 



Culex pretans Grossb. (The Brown-Striped Mosquito) . — This mos- 

 quito, prior to 1905, was classed among the rare forms. It had been 

 taken at various points in the State as an adult, but only once were 

 larvae found, and then only a few among a lot of canadensis and 

 sylvestris in the Great Piece meadows. 



In the season just passed it was again sought in spring, in the 

 Great Piece meadows, and to our surprise was found in swarms with 

 equal numbers of canadensis. This state of affairs occurred only on 

 the north side of the Passaic river; on the opposite side canadensis 

 was the dominant form, and not a single larva or adult of pretans 

 could be found. (The meadow on the south side is a mile or so 

 further up the river.) 



Larvae, full grown, were taken April 19th, in company with cana- 

 densis, a few cantans and a still smaller number of auiifer, sylvestris 

 and Aedes fuscus. On the 21st pup^e began to form rapidly, and on 

 the 23d the first adults, ten males and one female, emerged. April 

 24th, thirty-five males and eleven females emerged, and on the 25th, 

 six males and eight females. Another collection, made April 24th, 

 principally for specimens, turned up a lot of pupae, and on the 26th, 

 sixty-six males and three females emerged; the following day fifty- 

 two males and fifty-two females, and on the 28th, six males and 

 twenty-six females. Two or three specimens issued on the 29th, and
