eyes large, ovate and protruding; ocelli small, inconspicuous, about equidistant from each olher and 

 from the eyes and situated high up near the base of the head far above a line drawn through centers of 

 eyes; inferior margins of genae sloping, sinuate, and shghtly turned forward; clypeus broad with small 

 lateral lobes, extending for half its length below inferior margins of gense. Pronotum convex. robust, 

 gibbous, with strong suprahumerals and a long posterior process; metopidium vertical, higher thaii 

 broad; mediam carina faintly percurrent; humeral angles we;ik and blunt; suprahumeral horns strong, 

 laterally flattened, much longer than the distance between their bases. extending upward and somewhat 

 forward with the tips bent outward; posterior process long, slender, tricarinate, lyinj^ close to the 

 scutellum, impinging on the tegmina, tip decurved, blunt, and reaching beyond the tips of the tegmina ; 

 scutellum very narrowly exposed on each side. Tegmina long, narrow and pointed, hyahne; base 

 narrowly coriaceous and punctate; veins strong; five apical and three (sometimes four) discoidal cells ; 

 tip sharply pointed; apical Umbus narrow. Legs simple; hind tarsi longest.

 and there are only two discoidal cells in the tegmina. Head subquadrate, wider than high; base 

 arcuate and strongly sinuate; eyes large, globularand protruding; oceUi large, conspicuous, equidistant 

 from each other and from the eyes and situated a Uttle above a Une drawn through centers of eyes ; 

 inferior margins of genae sloping and strongly sinuate, edges turned forward; clypeus broad, trilobed, 

 extending for half its length below inferior margins of genae, tip truncate Pronotum convex, gibbous, 

 bearing strong suprahumerals and a stout posterior process ; metopidium vertical, about as broad as 

 high; median carina faintly percurrent; humeral angles heavy, triangular and bhmt; suprahumeral 

 horns strong, triquerate, much longer than the distance between their bases, extending outward and 

 upward andsUghtly forward; posterior process long. heavy, tectiform, triquerate, very close to scuteUum 

 and impinging on tegmina, tip sharp. decurved and reaching almost to tips of tegmina; scuteUum
