second example. It is a small species, similarly coloured 

 to P. Erichsoni, but the scutellum is black, and the black 

 apical patches of the elytra fade quite gradually in front. 

 The horn upon the head is slender and distant from the 

 front of the clypeus. The labrum is very prominent but 

 not pointed, and the mandibles are rounded at the sides. 

 The elytra are moderately broad at the shoulders and 

 taper to the extremities. They are marked with deep and 

 almost equidistant striae, and the subsutural and humeral 

 intervals are slightly punctured. The hind tarsi are twice 

 as long as the tibiae, the joints are circled with long, 

 stiff, outstanding bristles, and the claws are moderately 

 long but less than half the length of the claw-joint.

Two specimens have been presented to the Museum by 

 Sir William Ingram. 



It is a uniformly dark species. The eyes are rather 

 small and distant and the cephalic horn is short and sharp 

 and situated considerably behind the front margin of the 

 clypeus. The labram is narrow, rounded at the apex and 

 not tapering, and the mandibles are uniformly curved 

 externally and not sinuated. The anterior depression of 

 the pronotum is divided in the middle by a slight longi- 

 tudinal carina and the elytra are not long, moderately 

 convex and deeply striated, the striae very coarsely but 

 indistinctly punctured and the interstices smooth except 

 the subsutural and humeral ones, which bear a few 

 irregular punctures. The middle and hind tarsi are about 

 twice the length of the tibiae, the claws are moderately 

 long (more than half the length of the claw-joint), and the
