preempt the latter. The male genitalia of P. schmidti Melichar are quite 

 close to those of Homalodisca triquetra (Fabricius), the type-species of 

 Homalodisca. The two genera are not synonymized at this time, because 

 the action is a grave one and because males of P. compressa Walker are 

 unknown at this time. Species of Propetes can be distinguished from most 

 species of Homalodisca by the presence of a complete transverse sulcus 

 near the anterior margin of the pronotum, and the occurrence of a 

 faint median longitudinal elevation at the apex of the crown, both of 

 which characters are absent in Homalodisca spp., except the type. The 

 abdomen of Propetes spp. is constricted basally, but this character also 

 occurs in some species of Homalodisca.

Length 16-20.5 mm. 



Head strongly produced, median length exceeding interocular width, 

 apex not carinate, ocelli much closer to posterior margin than to apex, 

 located on a line between anterior angles of eyes, each about equi- 

 distant from adjacent eye angle and median line, surface usually 

 without an M -shaped elevation bordering posterior margin, with or 

 without a median fovea which is shallow and either partial or com- 

 plete when present, disc without setae, lateral clypeal sutures extend- 

 ing onto crown and attaining ocelli; antenna! ledges slightly protu- 

 berant in dorsal aspect, longitudinally foveate, in lateral aspect carinate 

 dorsally, anterior margins not steeply declivous; clypeus regularly- 

 convex, not flattened nor depressed medially; transclypeal suture 

 obsolete; face finely pubescent below; clypellus not produced, its 

 contour continuing profile of clypeus. 



Thorax with pronotal width less than transocular width of head, 

 lateral margins divergent anteriorly, disc rugose and usually punctate, 

 without pubescence, posterior margin concave, in lateral aspect with a 

 complete dorsopleural keel which is slightly oblique and slightly 

 curved downward near its anterior end ; scutellum usually transversely 

 striate on posterior portion. Forewing with membrane not sharply
