at Lake Hopatcong, and on the twenty-ninth of that month a female 

 with developed ova was caught in the Moonachie woods near Carlstadt. 



Other captures in 1903 came from Cape May, July 28, August 11, 

 and September 21 ; Chester, Morris County, August 9 ; South Orange, 

 August 26 and Arlington. In none of these places were more than three 

 or four specimens collected. 



In 1904 and 1905 not an adult was secured anywhere except at Laha- 

 way, and there they were present in their usual abundance. On June 4, 

 of the later year, a male was among the captures, the second specimen 

 of that sex taken. Search for the larva was continued in these two years, 

 and particular attention was paid to the cedar swamp between Barne- 

 gat and Manahawken, where it was supposed that they might breed and 

 migrate to Lahaway. Areas to the south and west of Lahaway were also 

 explored; but in no place was even as much as one adult found. In 

 searching for larvae no body of water was too small or too large to be 

 passed without notice ; with a net the surface and the bottom were 

 swept, stones in the water were overturned, taken out and inspected, 

 logs, branches, and limbs of trees were drawn out in the hope of finding 

 them clinging to their surfaces ; the bottom material was scooped up 

 and closely scrutinized, weeds and scums were investigated and plant 

 stems were even split open to see whether they contained larvae ; in 

 short, everything in the water, animate and inanimate, was examined ; 

 but without success. 



From the beginning the capture of perturbans so far inland as Lake 

 Hopatcong rather opposed the idea that the species bred only along the 

 borders of the salt marsh, and the fact that a male was among those 

 taken, was almost convincing to the contrary. Again, the fact that a 

 male was taken also at Lahaway, pointed toward local breeding, but a 

 decided argument that they did not breed at Lahaway lay in the fact 

 that none of the females taken there showed traces of developing ova — 

 a peculiarity true also of the salt water species that migrate from the 

 marshes. Concerning the habits of the adults Mr. Brakeley says : "They 

 are found all over, in the woods, in the open and on the cranberry bogs 

 and get into one's ears and eyes ; they get into the bedroom and into the 

 dining room and at the table they go for the ankles." 



In 1906 adults were encountered in some numbers in the Great Piece 

 meadow on August 27, congregated over an acre or two of territory in 

 the center of which was a large pool of water rather thickly overgrown 

 with vegetation. Heretofore this pool had yielded only Anopheles and 

 C. territans; but now it seemed obvious that it harbored perturbans as 

 well. The mosquitoes were most abundant around the edges of the pool
