54. GENUS PROTERPIA STAL 



Proteppia Stal, Bid. Hein. Syst. 557 (1867). 



Cliaracters ; Large robust insects, distinguished by the porrect suprahumeral horns with blunt, 

 truncate or rounded tips and by the fact that the tegmina are about half concealed by the overhanging 

 sides of the pronotum. Head subquadrate, twice as wide as high ; base sinuate ; eyes prominent, glassy ; 

 ocelii small, about equidistant from each other and from the eyes; inferior margins of genae rounded; 

 clypeus broad and extending for about half its length below inferior margins of genae. Pronotum tecti- 

 form, highest in middle; metopidium straight; median carina faintly percurrent; humeral angles blunt, 

 triangular; suprahumeral horns stout, robust. projecting forward and slightly upward, nearly parallel 

 with each other, slightly compressed laterally with usually a lateral carina, tips rounded; posterior pro- 

 cess heavy, straight, tectiform, sharp, reaching just beyond the tips of tegmina; scutellum entirely hid- 

 den. Tegmina subopaque, pubesceut, about half covered by the sides of the pronotum ; five apical and 

 two discoidal cells; median apical cell truncate at base ; apical limbus narrow. Legs simple; hind 

 tarsi a little longer than the others.
