Apparently allied to P. aurantiaea (Saussure and Zehntner), 

 but differing in the larger size, the longer pronotum and different 

 coloration. 



General form elongate, graceful ; surface glabrous. Head with the interspace 

 between the eyes but slightly less than that between the antennal bases, and 

 considerably exceeding the loug diameter of the eye; eyes subovate, moderately 

 conspicuous; antennae elongate, considerably exceeding the body, heavily plu- 

 mose in the basal third. Prouotum rather elongate, the posterior width much 

 greater than the anterior; anterior margin truncate, posterior very obtuse angu- 

 late, lateral margins expanding posteriorly. Tegmina elongate ; anterior margin 

 moderately sinuate, apex rounded ; costal nervures numerous (about 13), basal 

 field narrow; discoidal field with the veins longitudinal and seldom forked; 



*As a new subfamily name is required for this group I propose the above, 

 based on the oldest genus.
