EXPERIMENT STATION REPORT. 635 



Grossbeck suggests in his report: ''A dozen others [co/yitator^ 

 were taken on the weather-boards under a porch on Springfield 

 avenue. It is worthy of note that this dwelling was close to the 

 spot where C. sylvestris was found breeding on May 3d, and that 

 no specimens of this species were seen at this time. In no instance 

 was any species other than C. cantator seen in the roadways or on 

 houses where we looked. 



"On the other hand, when we got into the woods, cantator dis- 

 appeared and ^{phonalis \^ab fitcliii'] was common, and bit raven- 

 ously. C. siphonalis is scarcely to be distinguished from cardans 

 in the adult stage and not at all when they are even slightly flown •,. 

 but since the larvae of the former species were common here May 

 2d, it is safe to say that this is the species we noAV encountered."' 

 Two exam23les of C. pretans were also taken. 



June 3d, a box of specimens said to have been captured on the 

 South Mountain Reservation were sent in by Mr. Renwick with 

 the statement that "mosquitoes were very hungry in the reserva- 

 tion." These were twenty abfltchii and four cantador. These are 

 the two species found by Mr. Grossbeck a few day previously, and 

 the sending indicates a woods rather than a road capture. 



June 5th, Mr. Brehme again covered the temtory from South 

 mountain to Millburn, taking no adults on the way, but turning 

 out a few larvse between Short Hills road and the cemetery. These 

 were found to be half-grown C. sylvestris and a few C. trivittatus. 

 Later in the day, on the South Mountain Reservation, twenty-three 

 adults were taken, twenty cantator and three sollicitans, the latter 

 making its first appearance in the marsh migrations. 



June 11th. on the South Mountain Reservation all the pools 

 were dried out, but 118 adults were collected, of which 117 were 

 co/ntator and one was canadensis. At Millburn and Short Hills 

 breeding conditions were very similar, and as the wind was blowing 

 briskly no adults were found flying. 



June 14th, Messrs. Brehme and Grossbeek again covered the 

 gi'ound together and found absolutely no local breeding in progress. 

 In the bright sunny roadways no mosquitos were found. In the 

 SAvampy woodland area tetween Millburn avenue, Morris turnpike 

 and Short Hills road mosquitoes were present in great numbers, 

 and with few exceptions they were cantator, the salt-marsh species ; 

 the exceptions were either cantans or ahfitchii, probably the latter.
