136. GENUS THRASYMEDES KlRKALDY 



Thrasymedes (nom. nov.) Kirkaldy, Ent. XXXVII : 279 (1904). 

 Phacusa (preoccupied) Stal, Hem, Mex. 72 (1864). 



Characters : Medium sized, elongate insects with low, convex, unarmed pronotum, triangular 

 head, tegmina entirely free and showing five apical cells and one discoidal cell. Head triangular, very 

 roughly sculptured; base arcuate ; eyes large and globular; ocelii large, conspicuous, equidistant from 

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

 margins of gense weakly sinuate; clypeus swollen, distended, extending for one-third its length below 

 inferior margins of genae. Pronotum low, convex, unarmed ; dorsum straight; metopidium sloping, 

 wider than high: median carina obsolete ; humeral angles weak and rounded; sides of pronotum punc- 

 tate but not ridged, shghtly impressed behind humerals; posterior process slender, convex, apex sharp 

 and reaching just beyond the internal angles of the tegmina. Tegmina entirely exposed ; hyaline; five 

 apicalcells; one discoidal cell; apical limbus broad. Hind wings with median apical cell truncate at 

 base. Legs simple; hind tarsi longest. 



Type flavomarginata Stal.

137. GENUS EURITEA Stal 



Euritea Stal, Bid. Hem. Syst. 552 (1867). 



Characters : Near the preceding genus but distinguished particularly by the fact that there 

 are at least two complete discoidal cells in the tegmina. Head subovate, roughly sculptured; base 

 arcuate ; eyes large and globular; ocelli large, prominent, elevated, equidistant from each other and 

 from the eyes and situated on a line drawn through centers of eyes; inferior margins of genae rounded: 

 clypeus with tip rounded and extending very little below the inferior margins of the genae to carry out the 

 semicircular apical outline of the face made by the gena^. Pronotum low, weakly convex, unarmed ;
