The Cicadellidae of Kansas.* new v.-.^^k 



BY P. B. LAWSON. BOTANlC.a 



INTRODUCTION. 



The first attempt to make a list of the Cicadellidse of Kan- 

 sas seems to have been made by Professor E. A. Popenoe, 

 who in 1885, in the Transactions of the Kansas Academy of 

 Science, voL IX, p. 63, listed a few of the members of this 

 family that he had personally collected in the two preceding 

 years. Nothing more seems to have been done along this 

 line till the year 1905, when there appeared a list of the Kansas 

 species in the Transactions of the Kansas Academy of Science, 

 vol. XIX, p. 235, by Mr. F. F. Crevecoeur, in which some eighty 

 species and varieties were reported, nearly if not all of them 

 taken by himself, within a few miles of his home at Onaga, 

 Kan. He was followed by Mr. E. S. Tucker, who in 1906, in 

 vol. XX, part 2, p. 192, of the same publication, added twenty- 

 three species to Mr. Crevecoeur's list, all of these species being 

 taken in Douglas county. A fourth list was published in 1907 

 by the same writer in the Kansas University Science Bulletin, 

 vol. IV, p. 65, where were listed the species taken by him in 

 Douglas and Sedgwick counties. And finally, in 1911, there 

 appeared a complete list of all the Cicadellidse taken in the 

 state to date, by Mr. S. E. Crumb, who published his list, along 

 with available host plant records, in the Transactions of the 

 Kansas Academy of Science, vol. XXIV, p. 232.
