This species belongs to the group—including P. glabri- 
collis, Bates, and P. pactor, Lameere—in which the third and 
fourth joints of the antenne are unarmed, and in which the 
succeeding joints up to the tenth are angulately or spinosely 
produced at the innerapex. The species can be easily enough 
recognized by its distinct coloration. The punctures of the 
elytra are exceedingly minute at and beyond the middle, but 
are somewhat stronger towards the base. he lees are 
densely and somewhat strongly ae. The scape of 
the antenne bears a distinct carina at the apex. The pro- 
and mesosternal processes are tubercled.

Long. 40-60, lat. 11-17 mm. 
Hab. Brazil. 
Clothed entirely with a dense tawny or greyish tawny 
pubescence, which is thicker and somewhat silky on the 
underside of the body. Head with a broad, obtuse, and 
feebly raised carina on the vertex between the antennary 
tubercles. Eyes moderately large, the lower lobes each 
forming a triangle, whose obtusely pointed anterior termina- 
tion is but little sunk beneath the projecting margin of the 
antennary condyle. Prothorax transverse, constricted at the 
base and apex; the anterior margin of the pronotum slightly 
projecting and ‘rounded in the middle; the disk with about 
five obtuse tubercles. Elytra (which are apt to be rubbed 
bare of their pubescence in places) with the apices truncate 
for a short distance from the suture, and briefly spined at the 
suture. Intermediate and posterior femora each with a short 
spine or tooth at the posterior distal extremity. Tibie each
