Characters : This genus is closely related to Oxyrhachis but has four apical cells in the hind 

 wings and lacks the ampliated inferior keel on the posterior process. It differs from Gongroneura in 

 having no elevations of the posterior process. Head subquadrate, a little longer than wide, roughly 

 sculptured; base arcuate and sinuate with a slight suggestion of a tubercle on each side of the median 

 line; eyes small, ovate, and more or less flattened ; ocelli large, conspicuous, protruding, equidistant 

 from each other and from the eyes and situated on a line drawn through centers of eyes; inferior 

 margins of gen^ produced downward in sharp-cornered quadrangular foHaceous lobes; clypeus long, 

 narrow, not extending below the inferior lobes of the gen£e, tip rounded or truncate. Pronotum 

 convex, gibbous, bearing stout suprahumerals and a long posterior process ; metopidium vertical, a 

 little wider than high; median carina strongly percurrent; humeral angles short, lieavy and blunt; 

 suprahumeral horns var^ing in size and structure but usually short and stout, extending upward and 

 forward and very shghtly outward, tricarinate, somewhat swollen, tips blunt; posterior process long, 

 slender, tectiform, nearly straight, covering the scutellum and impinging on the tegmina, tip blunt and 

 reaching beyond the abdomen and ahnost to the tips of the tegmina; scutellum entirely concealed. 

 Mesothorax and metathorax armed with strong lateral teeth. Tegmina subhyaline or semiopaque, 

 entirel}' free ; base coriaceous and punctate; veins strong and raised; five apical and four discoidal cells; 

 apical limbus broad. Hind wings with four apical cells. Legs short and stout; femora cyhndrical; 

 all three pairs of tibiae flattened and foli;iceous; hind tarsi longest.
