Order HOMOPTERA 



The list in the order Homoptera has not had, properly speaking, a 

 general editor, although Mr. E. P. Van Duzee was originally designated 

 as in charge of this order at the time when the preparation of the state 

 list as a whole was first contemplated. Pressure of other duties, and the 

 transferral of Mr. Van Duzee's residence to California, have prevented 

 him from continuing to take the general responsibility. While the Editor- 

 in-Chief has assembled the data for many of the groups, Mr. Van Duzee 

 has done an immense amount of work in making determinations, furnish- 

 ing records, and correcting synonymy, with the exception of the specialized 

 families Coccidae and Aphiidae, which have been checked over by Messrs. 

 Harold Morrison, and A. C. Baker and P, W. Mason, respectively. Mr. 

 Van Duzee has been kind enough to look over the proof also. 



The following families of this order are especially well represented in 

 the State, due to the collecting and study by the specialists mentioned 

 in connection with them : Cicadidae, Wm. T. Davis ; Membracidae, W. D. 

 Funkhouser, L. B. Woodruff, C. E. Olsen, and J. L. Buys; Cicadellidae, 

 Herbert Osborn, D. M. DeLong, C. E. Olsen, and J. L. Buys; and for all 

 three of these groups, of course, E. P. Van Duzee.

^' There are but nine species of cicadas in New York State, whereas more inland areas, as 

 Kansas and Colorado, have about twenty-five species each, and on the Pacific coast they are even 

 more numerous. In Tibicen auletes, however, the State has one of the largest of North American 

 cicadas, and in T. chloromera one of the most noisy and energetic. With the exception of the 

 seventeen-year cicada, practically nothing is known of the life cycle of any of the specieg,
