Systematic Treatment of Kansas Species. 



Van Duzee in his catalogue of the Hemiptera of America 

 north of Mexico, divides the Cicadellidse into five subfamilies, 

 which may be separated by the following^key : 



A. Ocelli below margin of vertex. 



B. With a distinct margin between the vertex and the front. 



Paropinas. 

 BB. Without a distinct margin between the vertex and the front. 



By thoscopinse. 



AA. Ocelli, if present, on or above margin of vertex. 

 B. Ocelli on disc of vertex. 



C. Body elongate, cylindrical. Cicadellinv. 



CC. Body more robust, flattened. Gyponinse. 



BB. Ocelli, if present, on or near the margin of vertex. 



Jdssinse. 



The Paropinse do not occur in the state, being found only 

 west of the Rockies. 



Subfamily BYTHOSCOPIN^E (Dohrn). 



The members of this subfamily are in the main short and 

 broad species, having the ocelli below the margin of the vertex 

 on the front, and with no distinct margin between the vertex 

 and the front. 



KEY TO GENERA. 



A. Anterior margin of pronotum not distinctly produced beyond an- 

 terior margin of the eyes; vertex rounded anteriorly. 

 B. Head as wide as, or wider than, pronotum. 

 C. Elytra without a distinct appendix. 

 D. Pronotum finely granulated. 



E. Posterior margin of vertex elevated, forming 



irregular curve. Agalliopsis. 



EE. Posterior margin of vertex normal, forming 



regular curve. Agallia. 



DD. Pronotum transversely and coarsely granulated. 



A cera taga Ilia. 



CC. Elytra with distinct appendix. Idiocerus. 



BB. Head narrower than pronotum. Bythoscopus. 



AA. Anterior margin of pronotum distinctly produced beyond anterior 

 margin of the eyes ; vertex obtusely angulate. 



B. Striations of pronotum oblique. Macropsis. 



BB. Striations of pronotum transverse. Oncopsis.
