deplanata, sutura costisque carinatis quatuor integris apicem fere 

 attingentibus alteraque basali abbreviata utrinque praedita, inter- 

 stitiis profunde alveolatis ; corpore subtus abdomine excepto, 

 pedibusque breviter albido pubescentibus. 



Long 20-24 mm. ; lat. 6-7 mm. 



This species is distinguished from its South African congeners 

 with alveolate elytra : such as P. amatonga and P. consobrina, Per., 

 by the long and slender prothorax, and the white pubescence on the 

 scutellum, the base and apex of the elytra. 



In one of my examples the left antenna is only 9-jointed, and the 

 right 10-jointed, but the apical article is greatly reduced.
