 portion of the pronotum far less bulbous, no distinct step before the posterior process, and with the 

 suprahumeral horns and the posterior process very sharp and acuminate. Head triangular, broader

 about equidistant from each other and from the eyes and situated on a hne drawn through centers of 

 eyes; inferior margins of genae straight; clypeus broad and continuing the line of the face made by the 

 margins of the genae. Pronotum heavy and elevated, somewhat swollen in front but with no sharp step 

 before the posterior process; median carina almost obsolete; metopidium convex, wider than high; 

 humeral angles weak and rounded; suprahumeral horns heavy, conical, sharp, extending almost 

 directly outward ; posterior process heav}', gradually acuminate, tip sharp and reaching a point about 

 half way betweeii the internal angles and the apices of the tegmina; scutellum entirely hidden, Tegmina 

 free, broad, vitreous hyaline ; veins prominent; five apical and two discoidal cells; all cells of the 

 corium long and narrow; apical limbus broad. Legs simple; tarsi all about equal in length.
