Diagnosis. Greenish ochraceous, lateral margins of crown, pronotum, forewing clavus mesad of claval suture and apical margin narrowly reddish brown to piceous. Lateral margins of crown straight for short distance in front of eyes then strongly convergent, apex bluntly angled. It resembles female P. umbrosa but has more strongly convergent lateral margins of crown in addition to differences in coloration of pronotum and forewings.

Description. Distant (1908) adequately described the external features of this species. Additional features are as follows. Crown without prominent median suture, lateral margins in front of eyes straight for a short distance and then convergent, apex bluntly angled; about 0.97× as long medially as interocular distance, about 1.4× as long as median length of pronotum. Pronotum with lateral margins divergent posteriorly, distance between posterolateral angles about 1.2× as long as distance between anterolateral angles. Mesonotum shorter than median length of pronotum.
