THE PERIODICAL CICADA ON LONG ISLAND, 

 N. Y., IN 1910. 



By William T. Davis, . 

 New Brighton, Staten Island, N. Y. 



On the third of July, 1910, I walked in the Half Way Hollow Hills 

 near Wyandanch, Long Island in quest of the seventeen-year cicadas 

 that were reported by Mr. Frederick M. Schott earlier in the season. 

 I found that their presence was well known to the residents of the 

 district and many of the pupa skins were lying on the ground about 

 the edge of a cultivated tract. The cicadas had come up among the 

 young trees of about ten years' growth, which surrounded the field on 

 two sides. Across the road I found the pupa skins very common in a 

 cleared wood-lot, and a great many of them were clinging to the piles 

 of cord wood. There were also many holes in the ground both 

 here and in the locality last mentioned, from which the cicadas had 

 emerged, and I found where they had laid their eggs in white birch, 

 white oak, scarlet oak and Popuhis grandidentata. Though only parts 

 ■of dead cicadas remained at the time of my visit, yet they had been 

 very numerous, and I was informed that a woman had supposed she 

 heard the whir of a mowing machine in a nearby field, not knowing 

 ■of the presence of the seventeen-year locusts this year. 



The species occurred in great numbers in the same territory in 

 1906, and Mr. Holmes showed me the dead branches on his apple 

 trees that had died by reason of having so many cicada eggs laid in 

 them during that visitation.
