Genus JASSUS Fabr. 



In the members of this genus the head is distinctly narrower 

 than the pronotum, and seems to be set back on the latter. 

 The vertex is quadrate, not at all produced in front. The front 

 has distinct transverse striae. The pronotum is very short, 

 about the length of the vertex, the lateral portions well covered 

 by the head, with short lateral margins, long humeral mar- 

 gins, and the posterior margin slightly concave. The scutellum 

 is very large, wider than long. The elytra are rather short 

 and broad, broadly rounded apically, the nervures strong. 



A single species of the genus occurs in Kansas.
