Huh. French Guiana. 



This species belongs to the group — inchiding P. glahri- 

 coUis, Bates, and P. pactor, Lameere — in which the third and 

 iourth joints of the antennai are unarmed, and in which the 

 succeeding joints up to the tenth are anguhatelj or spinosely 

 jiroduced at the inner apex. Tlie species can be easily enough 

 recognized by its distinct coloration. Tlie ])unctures of the 

 elytra are exceedingly minute at and beyond the middle, but 

 are somewhat stronger towards the base. The legs are 

 densely and somewhat strongly punctured. The scape of 

 the antennai bears a distinct carina at the apex. The pro- 

 and raesosternal processes are tubercled.

Castaneum, fulvo rel griseo-fulvo oranino denseque pilosum ; pro- 

 thorace supra tuberculato sparsissime puuctato, lateribus tube- 

 rosis, inajqualibus, basi apiceque constrictis ; elytris apice sub- 

 tnmcatis, sutura breviter spinosis ; femoribus intermediis pos- 

 ticisque apice breviter unidentatis ; antennis corpore paullo brevi- 

 oribus ( J ), medium elytrorum vix excedentibus ( $ ). 



Long. 40-60, lat. 11-17 nwn. 



Hah. 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 

 ■|)rojecting and rounded in the middle ; the disk with about 

 live 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. Tibi« each
