bushes and then migrated to the poplar. There was a little feeding 

 though by no means much upon this latter plant. 



■Dioryctria abietella Zinck. Specimens of the work of this insect 

 were received November 4, 19 15 from Mr G. G. Atwood, chief of 

 the bureau of horticulture, who states that the specimens were 

 from Austrian pines growing at Rochester, N. Y. 



The buds, evidently young growth, have been badly tunneled 

 by the caterpillars of this species, and in one recurved shoot, suggest- 

 ing somewhat the' work of Evetria bouliana, the remains 

 of a caterpillar were observed. Irregular, rather coarse particles of 

 reddish brown frass were attached here and there to the affected 

 shoots and in one instance formed a mass half an inch long and about 

 one-fourth of an inch broad. One woody twig with a length of 3 

 inches had been neatly tunneled by the borer, the gallery having a 

 diameter of nearly one-eighth of an inch. 



Periodical Cicada (Tibicen septemdecim Linn.) . The 

 appearance of this insect, more generally known as the seventeen- 

 year locust, is always interesting, particularly if it occurs in large 

 numbers. Brood six of the seventeen-year race has been char- 

 acterized by Doctor Marlatt as " an unimportant scattering broody" 

 and the published map showing its distribution indicates a wide 

 range from the state of Wisconsin south to Georgia, with an evident 

 concentration in western North Carolina, northwestern South 

 Carolina and northern Georgia, and a secondary center ranging along 

 the eastern boundary of Pennsylvania, through New Jersey into 

 New York, where it has been recorded more or less authentically 

 from Greene, New York, Richmond and Schenectady counties. 



Mr William T. Davis of New Brighton states that though he has 

 records from m.any localities i't was nowhere quite so common in 

 191 5 on Staten island as it was in 1881 or in 1898 and the distribution 

 appears to be sparing. He reports the insect from the government 

 reservation at West Point, Orange county, a new record, and a living 

 specimen was' received from Mr J. L. Livingston, Tivoli-on-Hudson, 

 Dutchess county. Mr W. H. Hart and his nephew, Mr C. S. 

 Hubbard, both reported having heard Cicadas in the town of 

 La Grange, Dutchess county, and another gentleman at La Grange- 

 ville stated that he had also heard a few Cicadas in nearby woods. 

 This is a locality where brood two, which appeared last in 191 1, was 

 exceedingly common and there is every reason for giving these reports 

 full credence. There is also a statement by Mr D. V. Haggerty 

 to the effect that this insect occurred in small niunbers near Wic- 

 copee, the extreme southern portion of the county. , Further-
