Characters. — ■ Head (including eyes) about as wide as base of mesonotum, its lenght about 

 or nearly equal to space between eyes, ocelli much farther apart from eyes than from each other, front 

 anteriorly convex and slighdy prominent; pronotum with the lateral margins moderately ampliate and 

 sinuate, the posterior angles dilated, a little shorter than mesonotum; mesonotum with the disk mode- 

 rately convex; abdomen in male longer than space between apex of head and base of cruciform eleva- 

 tion; tympanal coverings complete; opercula in male short and transverse ; rostrum passing posterior 

 coxae; anterior femora spined beneath; tegmina and wings hyaline, the first usually more 'or less macu- 

 late, basal cell longer than broad, apical areas eight. 



Type. — P. fusca, Olivier. 



Geographical distribution of species. — Oriental Region, China and Japan. 



A. Tegmina more or less spotted with fuscous, at least always on apices of longitudinal veins 

 at apical margins.
