FAM. MEMBRACID^ 223 



large, globular and protruding; ocelli large, prominent, twice as far from each other as from the eyes 

 and situated above a line drawn through centers of eyes; inferior margins of genae weakly lobed and 

 projecting slightly over the edges of the clypeus; clypeus extending for half its length below the inferior 

 margins of the genae, tip rounded. Pronotum elevated into an erect conical anterior horn which is 

 branched at the top; metopidium convex, vertical, broad at the base and narrow at the top; no median 

 carina; humeral angles broad and blunt; anterior pronotal horn conical, erect, branched at the top into 

 two lateral branches which usually extend directly outward, tips simple and sharp; posterior process 

 long, slender, usually decurved; arising from high on the pronotal horn, usually just below the lateral 

 branches, tip acuminate and reaching beyond the internal angles of the tegmina but not to their tips; 

 scutellum entirely exposed, long, narrow, reaching almost to the end of the clavus, generally swollen at 

 the base and often tomentose. Tegmina broad, hyahne ; base narrowly coriaceous and punctate; veins 

 strong; five apical and two discoidal cells; tip rounded; apical limbus broad. Hind wings with four 

 apical cells. Legs slender and simple; hind tarsi longest.

Characters : This genus is very distinct from the other genera of the tribe because of the fact 

 that the posterior process lies close to the body, almost concealing the scutellum and impinging on the 

 tegmina and because the anterior pronotal horn is dilated or much thickened at ihe apex. Head 

 subquadrate, broader than high; base arcuate and sinuate and sometimes weakly bituberculate; eyes 

 very large, globular and protruding; ocelli large, conspicuous, farther from each other than from the 

 eyes and situated above a line drawn through centers of eyes; inferior margins of genae short, rounded 

 and weakly lobate; clypeus trilobed, the median lobe much the largest, extending for more than half 

 its length below inferior margins of gena;, tip rounded. Pronotum elevated into a high, conical or 

 cyHndrical anterior horn which is usually forked at the top; metopidium vertical, about as high as its
