Characters. — Body robust, somewhat short ; abdomen in male about as long as space between 

 apex of head and base of cruciform elevation; head broad, truncate anteriorly, including eyes a little 

 or scarcely broader than base of mesonotum, ocelli about twice and sometimes thrice the distance 

 from eyes as from each other, face moderately convex not prominent above; pronotum with the lateral 

 margins ampiiated or laminately medially angulate ; anterior femora not prominently spined: meta- 

 sternum with a central elevated plate-like process, which is centrally sulcated and posteriorly somewhat 

 sinuately truncate; tympana practically concealed by the tympanal flaps or coverings; opercula in male 

 short, broad, their apices more or less convexly rounded; tegmina and wings either hyaline or more or 

 less opaquely coloured, tegmina with the basal cell a little longer than broad, the costal membrane only 

 moderately dilated or arched at base, apical areas eight in number. 



Oxypleura, Amyot & Serville, merely includes species with hyaline non- opaque tegmina and wings : 

 Pacilopsaltria, Stal was regarded as distinct from Platyplenra by the slightly greater width of the head
