61. genus ICTARANTHE FOWLER 



lctaranthe Fowler, B. C. A. II : 79 (i8g5). 



Characters : Phylogenetically this genus is unquestionably very close to Hyphinoe Stal but if it 

 may be judged by the type species it bears a strong superficial resemblance to the genus Ceresa of the 

 subfamily Smiliinae. It differs from Hyphinoe in having sharp, acute suprahumeral horns and in having 

 the anterior portion of the pronotum much less bulbous, and it may be distinguished from Alcmeone in 

 having the cells of the corium irregular in shape rather than uniformly narrow and oblong. The more 

 imptortant generic characters areas follows : Head triangular, roughly sculptured ; base arcuate; eyes 

 ovate; ocelli large, prominent, equidistant from each other and from the eyes; inferior margins of 

 genae straight; clypeus ridged in center, extending for half its length below the inferior margins of 

 the gen£e. Pronotum elevated, somewhat swoUen in front, lightly impressed on each side; dorsum 

 convex and sloping ; metopidium convex, broader than high; median carina percurrent; humeral angles 

 triangular, blunt; suprahumeral horns strong, tricarinate, sharp, extending outward and upward ; 

 posterior process heavy, tectiform, sharp, extending to a point a little more than half way between the 

 internal angles and the apices of thetegmina; scutelhim entirely concealed. Tegmina free, liyaline, 

 broad; veins prominent; cells of corium irregular in shape; five apical and two discoidal cells; apex 

 rounded; apical limbus broad. Legs simple; hind tarsi somewhat longer than the others. 



Type latifrons Fowler. 



Geographlcal distribution : This genus is known only from the type species which was 

 described from Panama but has since been reported from Brazil. 

 I. latifrons Fowler, B. C. A. II : 79 (i8g5). — Pl, 5, fig. 52. Panama, Brazil. 



62. Genus HEMIKYPTHA METCALF 



Hemikyptha Metcalf, Ent. News XXXVIII : 16 (1927). 



Characters : This genus contains the largest insects in the family, some of the species 

 measuring more than twenty-five milhmeters in length and half that in heiglit, including the pronotal 



Note : Stal must be written Stal. We beg to apologize for the misprint occurring pp. i - 94 inclusive.
