Lawson: Membracid.e of Kansas. 91 



crest; breast jiitchy; abdomen black; a stripe on each side beneath and the 

 tip yellow ; legs yellow ; wings colorless ; fore-wings tawny at the base and along 

 more than half the length of the fore border; veins pitchy, tawny where the 

 wings are so, pale yellow near the tip of the fore border. 



Length of the abdomen, 2% hnes; of the wings, 4% lines. 



Var. /)' . Breast and abdomen tawny; white bands of the keel hardly visible. 



Var. y. Breast and abdomen black; tip of the latter tawn3\ 



St. John's Bluff, E. Florida. 



Internal male genitalia. Styles small, anterior portion narrow, 

 posterior part stouter, the apices curved strongly laterad and ending 

 in a stout hook; connective large, triangular, apex abtuse, and longi- 

 tudinally divided; oedagus, viewed laterally, U-shaped, anterior arm 

 with a distinct protuberance, posterior arm stouter and ending in a 

 large, serrated point. 



Distribution. Van Duzee reports this species from District of 

 Columbia, North Carolina, Georgia and Florida. It has been taken 

 in Douglas, Pottawatomie and Wilson counties, Kansas. 



Remarks. Funkhouser feels that E. sinuata is the very small 

 southern form, E. bactriana the northeastern, and that E. concisa is 

 our Kansas species. In the present confused status of the members 

 of this genus it is perhaps best to accept his conclusions and to 

 change our Kansas species to E. concisa instead of calling it E. sin- 

 uata, as did Miss Branch. 



Hosts. Miss Branch reports this species from Melilotus alba, 

 Cnicus altissinius, Phleum alpinum, Helianthus annuus, Medicago 

 sativa, and Ambrosia sp. The writer has taken it very commonly in 

 all its stages from Ambrosia triflda, Xanthium sp., and Helianthus 

 tuberosus. 



Genus Publilia Stal. 



The members of this genus are closely related to those of the pre- 

 ceding genus, but have a much lower crest and a much weaker me- 

 dian notch. 



All of the members of the genus found in the United States occur 

 in Kansas. These may be separated by the following key given by 

 Van Duzee. 



KEY TO SPECIES. 



A. Dorsum straight or feebly arcuated, scarcely if at all sinuated; form more 

 slender. mudesta. 



AA. Dorsum more elevated, obviously sinuated. 



B. Sides of the pronotum with longitudinal rugae which become more 

 or less reticulated along the dorsum. concava. 



BB. Rugae of the pronotum strong, irregularly reticulated over its whole 

 surface. reticulata.
