 551, pi. 1, figs. 6, 6a. 



Dark, glossy, iridescent, violet purplish with pale green mark- 

 ings, rostrum and legs metallic copper colored. Closely related 

 to P. erichsoni Waterh. Head with a small scale spot under 

 each eye. Prothorax with a narrow anterior marginal band, 

 another somewhat broader band at the middle interrupted dis- 

 cally, and traces of a posterior marginal band. Elytra with 

 rows of distinct punctures. Each elytron with two large oblong- 

 oval spots near base, one located discally, the other at lateral 

 margin; at the middle a crossband, reaching from first row of 

 punctures to eighth near lateral margin. At apical third a 

 longitudinal stripe at third interstice, reaching to apex, recurv- 

 ing as a submarginal stripe, thus forming roughly a triangle, 

 inside of which are located two oblong spots at fifth and seventh 

 interstices, respectively. 



Length, 11.6 millimeters; width, 5.5.

Related to P. erichsoni Waterh. but much stouter in build. 

 Glossy, dark wine red with violet sheen and pale yellowish green 

 scale markings. Rostrum very similar to that of P. apocyr- 

 toides, basal half depressed and flattened with a short but 

 strongly pronounced longitudinal medial groove. A scale spot 

 at sides of head. Prothorax as long as broad, with an anterior 

 submarginal stripe and a short abbreviated posterior submar- 

 ginal stripe dorsally. In the middle but toward each side a 

 rather large irregular scale spot and a large roundish spot at 

 each lateral margin. Elytra rather short ovate, strongly in- 

 flated, with moderately pronounced but regular rows of punc- 

 tures. Each elytron with nine scale spots, forming cross rows, 

 two at base, two in the middle, four others forming a cross 

 row at apical third, and one, which is triangular, near apex! 

 Legs metallic copper colored.
