FAM. MEMBRACID^ gS 



partly covered tegmina of the latter. This would be a good character if it vvere constant but \ve find 

 thal there is much variation in this respect in both genera since the development of the sides of the 

 pronotum is not uniform in either. Usually, however, in Bubalopa the corium is fully exposed, even 

 though the clavus may be concealed, and on the strength of this difference we are allowing the genus 

 to stand. The other characters are much the same as in Eualthe and are as foUows : Head triangular, 

 aboutas broad as high ; base strongly arcuate ; eyes distinctly triangular; ocelli large, prominent, about 

 equidistant from each other and from the eyes and situated slightly below a line drawn through centers 

 of eyes; inferior margins of genae sinuate; clypeus faintly trilobed, extending for half its length below 

 inferior margins of genae and continuing the line of the face made by these margins. Pronotum some- 

 what swollen anteriorly, tectiform, dorsum sinuate; metopidium straight, about as broad as high; 

 median carina percurrent; humeral angles very weak, rounded; suprahumeral horns strong, heavy, 

 triquerate, extending outward and upward; posterior process very long, slender, tectiform, gradually 

 acuminate, extending well beyond the apices of the tegmina; scutellum entirely concealed. Tegmina 

 ahnost entirely exposed, sometimes the clavus hidden; long, narrow, fuscous-hyaline, veins prominent, 

 tips rounded; five apical and two discoidal cells; apical limbus narrow. Legs simple; hind tarsi much 

 longer tlian either of the other two pairs. 



Type furcata Fairmaire. 



Geographical distpibution : The only species which are known in the genus were both 

 described from Bogota and have never been reported from any other locality. They are as follows : 



1. furcata Fairmaire, Rev. Memb. 314. 5 (1846). — Pl. 4, fig. 49. Colombia. 



2. obscuricornis Stal, Bid. Memb. Kan. 256. 2 (1869). Colombia. 



59. genus HYPHINOE STAL 



Hyphinoe Stal, Bid. Hem. Syst. 558 (1867). 



Characters : Robust, heavy-bodied insects with strong, blunt suprahumeral horns and free 

 tegmina. Head triangular, roughly sculptured; base arcuate; eyes triangular; ocelli about equidistant 

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

 margins of genae sinuate; clypeus broad, extending for half its length below inferior margins of genae. 

 Pronotum elevated, heavy and more or less swollen in front, usually impressed on each side; metopidium 

 convex, higher than broad; median carina weakly percurrent ; humeral angles weak, rounded; supra- 

 humeral horns heavy, triquerate, blunt, usually extending directly outward and very little upward; 

 posterior process suddenly narrowed because of a distinct step behind bulbous base, tectiform, blunt, 

 extending to a point about haif way between internal angles and tips of tegmina; scutellum entirely con- 

 cealed. Tegmina free, broad, semiopaque; veins heavy ; tips broadly rounded; five apical and two 

 discoidal cells; apical limbus broad. Legs simple; hind tarsi longest. 



Type cuneata Germar. 



Geographicai distribution : This genus is widely distributed over South and Central America 



and some of the individual species seem to have a wide range. The records up to the present are as 

 follows :
