The Seventeen- Year Cicada on Staten Island in 1907 1 



By Wm. T. Davis 



In 1890 two imago seventeen-year cicadas, Cicada septendecim 

 L., and three pupa skins were recorded from Staten Island (see 

 Proc. Nat. Sci. Assn. S. I. Feb. 10, 1894) . At that time there was 

 no known brood to which these insects could be assigned. 

 In 1898 Mr. C. L. Marlatt proposed a new nomenclature 

 for the broods of the periodical cicada, and at the same 

 time called attention to several broods that had remained un- 

 numbered. In Bulletin 18 (new series), U. S. Dept. of Agri- 

 culture, Division of Entomology, he writes as follows of Brood 

 XV : " This brood is represented by the colony appearing at Tivoli, 

 Dutchess County, and Galway, Saratoga County, N. Y., in June, 

 1890, as recorded by Prof. J. A. Lintner in his seventh report, 

 pages 297-301. Mr. Davis records the occurrence of scattering 

 individuals the same year on Staten Island. In a letter of June 2, 

 1890, Prof. J. B. Smith, New Brunswick, N. J., reports that the 

 periodical cicada had been taken by several Newark collectors, 

 and had also been observed at Anglesea, Cape May County."
