2 Bulletin of the Brooklyn Entomological Society Voi. viii 



In looking back over this period I am pained to realize how 

 many well known faces we now miss at our meetings, men like 

 those named above, whose places can pei-haps never be filled. 

 However, in resuming the publication of our Bulletin we 

 start imder better auspices than in 1878. The Society is consider- 

 ably larger and its meetings are well attended. Who can tell 

 what may be the entomological career of our younger and more 

 enthusiastic members ? Remember the words of Napoleon — 

 "Every private in the Grand Army carries in his knapsack the 

 baton of a field marshal." 



I bespeak a hearty welcome for our new venture, and I think 

 I can promise that members of tife Society will do their utmost 

 to make the publication interesting'-and instructive. 



A New Cicada [Homop.] from Plummer's Island, Maryland. 



By Wm. T. Davis, New Brighton, N. Y. 



Through the kindness of Mr. W. L. McAfee of the Depart- 

 ment of Agriculture, Washington, D. C, I have been able to 

 examine a collection of cicadas made at Plummer's Island, Md., 

 the home of the Washington Biologists' Field Club. In this col- 

 lection there are fifteen examples of a species heretofore con- 

 founded with Cicada linnei Grossb. and Cicada pruinosa Say. 

 These two very distinct insects cannot be readily told apart by 

 the examination of the male genitalia alone, but the costal margin 

 in linnei is more suddenly bent near the middle of the fore wing 

 than in pruinosa. They are also very differently marked. The 

 song of linnei is a continuous one rising higher in pitch if the insect 

 is energetic, and then gradually subsiding, in this respect some- 

 what resembling Cicada sayi, only it is not so loud and not so 

 impetuous as in that species. Cicada pruinosa has a very different 

 song, a z-zape, z-zape, z-zape. These two insects are therefore 

 very far apart in the character of their song. 



The cicadas from Plummer's Island, or Winnemanna as the 

 Indians called the region, were collected from 1902 to 1910, and 

 from July 12 to September 24. The majority were collected in 

 August. On two collected August 16, 1907, the song is noted by 

 McAfee as "a high-pitched rising and falling note": on two of
