Davis: Notes on the Seventeen-Year Cicada in 1911 3 



Wort, of Rossville, gave me two examples of this form collected 

 at that place June 18, 1911. The cicadas were not heard after 

 about the tenth of July, but in the Clove Valley, where they had 

 been particularly numerous, I heard a single belated male sing 

 four times on August 2. A living one was found in August 

 near the home of Mr. Benedict. While the cicadas were gen- 

 erally distributed over the wooded portions of Staten Island, 

 except the small so-called pine barren areas, yet, as has been 

 observed in previous years, they were much more numerous in 

 some places than in others. In 1877 there were a great many 

 seventeen-year cicadas in the garden at New Brighton surround- 

 ing the house where I lived. Though the same fruit trees are 

 standing and the conditions, as regards vegetation have not par- 

 ticularly changed, yet I failed to find any of the cicadas in 1911.. 

 They have no doubt been exterminated by the house sparrow. 



It is well known that the seventeen-year cicada does not occur 

 in the New Jersey pine barrens, that is, in the real pine barren, 

 areas. Some of the maps showing this area include, erro- 

 neously, we think, all of the country about Lakewood, South 

 Lakewood, Ridgeway, etc., which in many cases supports an oak 

 forest with some large pig-nut hickories, chestnuts and sweet- 

 gums. Pines are not common in some portions of this area, and 

 three of the trees above mentioned do not belong to a pine barren 

 country. As a further proof in this matter I can state that the 

 seventeen-year cicada was very common in 191 1 in places near 

 Lakewood, South Lakewood and Ridgeway, being confined to the 

 areas of oak timber. Elsewhere in New Jersey we observed the 

 cicadas along Cheesequake Creek, at Matawan, about Terrace 

 Pond in northern New Jersey ; also at Hewitt, Haskell, Pompton 

 Junction, Little Falls, Great Notch and Ramsey.
