Genus Platymetopius Burm. 



This genus is characterized by its long pointed vertex, nar- 

 row front, and characteristic venation. The elytra have three 

 anteapical and five apical cells, two cross veins between the 

 first and second sectors, and eight to ten oblique veins in the 

 costal cell. They are also marked with fine brown pigment 

 lines, and the cells, especially the anteapical and apical, may 

 contain oval white spots. 



Only five species of this genus have been taken in Kansas.
