NOTES ON SOME CICADAS FROM THE EASTERN 

 AND CENTRAL UNITED STATES WITH A DE- 

 SCRIPTION OF A NEW VARIETY OF 

 CICADA PRUINOSA.i 



By Wm. T. Davis, 



New Brighton', Staten Island, N. Y. 



Under the name Riliana grossa Fabriciiis, W. L. Distant in his 

 Synonymic Catalogue of Homoptera, Part i, Cicadidse, London, 

 1906, includes as synonyms Cicada marginata Say (1825), Cicada 

 auletes Germar (1834), Cicada rcsh Haldeman (1852), Cicada sonora 

 Walker (1850), Cicada rcsonaus Walker (1850), Fidicina litcrata 

 Walker (1850), Cicada margiiialis Walker (1852) and Fidicina 

 figurata Walker (1858). In using the specific name grossa for the 

 largest cicada in the eastern United States Distant follows the 

 synonymy suggested by Prof. Uhler in 1905. 



It appears to the present author, however, after going over a 

 considerable number of specimens accumulated during the past few 

 years, that several of the names considered as synonyms really refer 

 to very distinct species and he has here tried to clear up the matter to 

 some extent. Mr. E. P. Van Duzee thinks that the generic name 

 Tibicen should be used for the species here mentioned; they are placed 

 under Rihana by Distant, as stated above. However, as they were

 H. Cleaves, of the Staten Island Association of Arts and Sciences.
