Distribution: Not yet reported for Kansas, but should be 



found. 



Hosts: Doctor Ball gives wild rose as the host plant of this 



species. 



Genus Phlepsius Fieb. 



The members of this genus are generally robust species with 

 vertex broad, usually distinctly longer on middle than next the 

 eye and obtusely angled. Their chief characteristic is the 

 marking of the elytra with brown ramose pigment lines which 

 are not confined, as in Eutettix, to any particular part of 

 the elytra. Due to these lines the species are, with few excep- 

 tions, brownish, but even in these exceptions, the ramose lines 

 are found. 



All of the twenty-one species keyed below have been found 

 in Kansas.
