in subcostal area and a large dark fuscous cloud over third apical 



cell; vertex nearly smooth P . ocellaris sp. nov. 



Ocelli medium to small; second and third apical cells not subequal in 



length and parallel sided, their basal cross veins usually strongly 



dislocated. 



•\ Median carina strikingly different on anterior and posterior halves 



of vertex; outer apical vein in tegmina strongly curved or sinuate; 



vertex and tegmina apically without large black spot. 



c\ Tegmina long and slender; outer apical vein strongly outcurved; 



second apical cell with subparallel sides; head distinctly narrower 



than pronotum, two oblique subcostal stripes; median carina of 



vertex strong on anterior half, on basal half appearing as a fine 



line set in an incisure; vertex in large part with wrinkled surface.

pronotum ; three oblique subcostal stripes ; median 



rior half; vertex in large part

Median carina of vertex complete and equally strong throughout. 

 \ Vertex nearly smooth except for a few indistinct wrinkles. 

 d\ Outer apical vein very strongly curved; head and tegmina apically 

 without large round black spots; vertex with a median yellowish 

 line; anterolateral margin of pronotum much longer than pos- 

 terolateral P. maiayana sp. nov. 



d 1 . Outer apical vein straight or nearly so; with a large round black 

 spot near apex of tegmina; anterolateral and posterolateral 

 margins of pronotum subequal. 

 e\ Vertex with an apical black spot; apex of tegmina evenly 

 rounded; first apical cell long and narrow. 



Vertex with a subapical transverse sanguineous band 



udad at sides; 



apex of tegmina somewhat emarginate 



beyond first and second apical cells ( ? in male) ; first apical 



cell very broad _ p. sangnineolineata sp. nov. 



c . Vertex in large part strongly conspicuously longitudinally wrinkled; 

 anterolateral margins of pronotum much longer than postero- 

 lateral. 

 d 1 . Black spot of vertex apical, preceded by a single median dark 

 line; vertex narrow, sides of head outcurved beyond eyes; first 

 apical cell long, second very large and broad, third very small.

 d*. Black spot of vertex subapical, preceded by two submedian black 

 lines; vertex broad, side of head not outcurved beyond eyes; first 

 apical cell short, second small and narrow, third very large.
