 the apical margin of the head at or near the eyes ; pronotum 

 transverse, very obtusely rounded at the apex ; scutellum 

 triangular, a little broader than long; tegmina almost as long as.

 with five apical cells ; legs moderate ; posterior tibiae very 

 spinose." (Stal.) 



Melichar located this genus in his Acocephalinse, by the presence 

 and position of the ocelli. Van Duzee places it at the commence-
