Professor P. J. Schmitt of St Vincent's College, Beatty, in- 

 formed me that the " Seventeen-year Locust" or " Periodical 

 Cicada" appeared on the grounds of the College in 1898 in small 

 numbers. The regular brood appeared in May, 1900. Beginning 

 at Sheridan, Cambria County, 1 noticed it as far west as Pitts- 

 burgh, as far north as Vandergrift, and as far south as Scottdale. 

 How far it extended beyond these limits I am unable to state. 

 The dwarfed form (var. cassina Fisher), seemed to be the com- 

 mon form.' 



Genus CICADA Linnaeus. 



318. C. tibicen Linnaeus. 



Beatty, Jeannette, Wihiierding, Pittsburgh. Common every- 

 where. 



219. C. canicularis Harris. 



This species occurs with the preceding. 



Family MEMBRACID^. (The Tree-Hoppers.)^' 

 Genus ENTYLIA Burmeister. 



220. E. sinuata Fabricius. 



Beatty, Greensburg, May 16, 1901. On grape vines. (Potato, 

 ragweed, sunflower, spikenard. ) 



221. E. bactriana Germar. 



Washington County ; Greensburg, May 16, June 2, 1903. On 

 weeds, most frequent at the edge of woods. 



1 The editor of the Annals in the spring of 1900 sent out a circular asking for infor- 

 mation as to the appearance of the Periodical Cicada, and received numerous replies 

 showing that the brood extended over the whole of western Pennsylvania from 

 Cambria county in the east to the state-line and beyond it into Ohio as far west as 

 Voungstown and Poland ; and from Grafton and Parkersburg, West Virginia, in the 

 south to Venango County, Pennsylvania, in the north. The brood probably extended 

 somewhat beyond these points, but no replies beyond them were received. The 

 insects were particularly numerous in the " Panhandle " of West Virginia.
