Characters : Near the preceding genus but with much shorter and differently shaped supra- 

 humerals and at once recognized by the irregular, reticulate venation in the apical areas of the tegmina. 

 Head subquadrate, about twice as broad as high; base lightly arcuate and sinuate; eyes small and 

 somewhat flattened, ocellismall, inconspicuous, equidistant from eachother andfrom the eyes andsituated 

 on a line drawn through centers of eyes ; inferior margins of genas sinuate and sloping only a very little; 

 clypeus broad, extending hardly at all below the inferior margins of the genae and continuing the apical 

 outline of the face made by those margins. Pronotum convex and bearing a pair of stout suprahumerals 

 and a long, heavy, tectiform posterior process ; metopidium vertical, convex, broader than high; median 

 carina faintly percurrent; humeral angles large, heav^-and blunt; posterior process long, heav}', tectiform, 

 curving downward, impinging on the scutellum and on the tegmina, tip acute and just about reaching 

 the tipsofthe tegmina; scutellum narrowly exposed on each side; suprahumeral horns stout, tricarinate, 

 as long as the distance between their bases, extending outward and upward. Tegmina broad, hyaline;
