Pronotum very foliaceous and laterally flattened, recalling the genus 

 Membracis; the anterior elevation extended forward before the head and 

 projecting more or less upward, never bilobed; very little hollowed out 

 above the scutellum ; posterior process well developed, extending backward 

 at least as far as center of body but not reaching tips of tegmina. Legs 

 flattened ; the tibiae, particularly the anterior pair, foliaceous. No supra- 

 humeral horns. Tegmina broad, the cells reaching the margin, without a 

 border ; five apical cells and one discoidal cell. 



The genus is native to the northern part of South America, 

 all of the species having been described from Brazil, Venezuela 

 and the Guianas. It contains at present nine species to which 

 must be added the following : 



Stegaspis viridis sp. nov. 



Green ; punctured ; prothorax subtriangular and much flattened ; poste- 

 rior process just reaching internal angle of tegmina; tegmina hyaline, 

 slightly punctured at base ; head subquadrangular, somewhat foliaceous ; 

 tibiae foliaceous. 



Head more or less quadrate, brown, finely punctured, not pubescent, 

 base smooth and arcuate ; eyes not at all prominent as seen from the front, 

 greenish and opaque; ocelli pearly, much farther from each other than 

 from the eyes and situated well above an imaginary line drawn through 

 the center of the eyes ; clypeus small, longer than wide, smooth, lateral 

 margins partly concealed by the overlapping edges of the adjacent genae. 

 Gense very large, extended, projecting downward as far as the inferior 

 margin of the labium, carrying out the general quadrate outline of the 

 head, very rough with minute tubercles ; antennae rather long, fine and 

 bristle-like. 



Pronotum roughly triangular, much flattened, projecting upward and 

 forward above the head, brilliant green in color, becoming yellowish in 

 cabinet specimens, finely punctured, the punctures smaller and closer 

 together at the anterior end than at the posterior, a smooth yellowish disk 

 just above and behind each eye; sides of pronotum bearing two or three 

 irregular, wavy, slightly raised lines ; median carina percurrent, very dis- 

 tinct on anterior margin, becoming more obsolete on dorsal margin, where 

 the tectiform ridge of the pronotum itself is very sharp ; humeral angles 

 small, not prominent; posterior process heavy, blunt, triangular, projecting 

 beyond the extremity of the abdomen and just reaching the internal angle 

 of the tegmen. 



Tegmina entirely hyaline ; base finely punctate and greenish ; apex broad 

 and much rounded, the veins extending to the margins ; veins broad, well- 

 defined, greenish. 



Abdomen very light green, segments faintly margined with darker ; 

 ovipositor more than half as long as ventral length of abdomen. 



Undersurface of thorax yellowish ; legs yellow-ferruginous, femora
