The Membracidae of Kansas. 



By P. B. LAWSON, 



Professor of Eiitoniologj', University of Kansas. 



INTRODUCTION. 



THE writer has been interested in recent years in a systematic 

 study of the Homoptera of Kansas. He has previously pub- 

 hshed papers on the Coccidse, Cicadelhda^ and Cicadidae of the state, 

 listing over 300 species of the members of these families known to 

 occur within the borders of Kansas. 



The membracids of the state have been previously studied by 

 Miss Hazel Branch, who in 1914 published a paper in the Kansas 

 University Science Bulletin, volume 8, on the biology of the 

 Membracidse of Kansas. In that paper she listed nineteen species 

 from the state. Since that time quite a little collecting has been 

 done, until to-day, including some species taken around Kansas 

 City, Mo., which species are therefore sure to occur in eastern Kan- 

 sas also, there are records of the occurrence of at least fifty-five 

 species of tree hoppers in our fauna. Further collecting will of 

 course reveal a goodly number of additional species, but the writer 

 has thought it advisable to bring our data up to date at this time. 



The writer is greatly indebted to Dr. W. D. Funkhouser, of the 

 University of Kentucky, who has made many determinations for 

 him and been very generous in giving helpful suggestions and en- 

 couragement during the course of this study. Moreover, his paper 

 on the biology of the Membracidse of the Cayuga Lake Basin has 

 been very freely drawn upon, especially in the use of the technical 

 descriptions. 



Through the kindness of Professors Geo. A. Dean and Roger 

 Smith, the records of the Kansas State Agricultural College are in- 

 cluded in this paper, most of the records from Riley county and sev- 

 eral others being from that collection.
