at tip ; upper lobe of maxillae horny, and produced into a nearly 

 vertical, slightly concave tooth, sharply bifid at tip, and another 

 strongly bifid near the base, last joint of maxillary palpi strongly 

 fusiform inwardly, straight or nearly so outwardly and nearly as 

 long as the three preceding it ; mandibles convex, bi-dentate, and 

 reflexed, inner tooth smaller than the other, and both rounded ; 

 clypeus greatly attenuate obliquely laterally, and reflexed at apex ; 

 head with a short, bifid tubercle in both sexes ; prothorax not 

 excavate or tuberculate ; elytra convex, a little ampliate laterally 

 past the middle, deeply and closely punctured in the dorsal part 

 from the base to past the middle ; anterior tibiae strongly tri-dentate 

 outwardly ; anterior tarsi of male thickened, penultimate joint 

 produced beneath the last one into a very distinct, transverse pro- 

 cess, inner claw thickened, strongly curved ; transverse carinas on 

 the intermediate and posterior legs sharply dentate in the outer 

 angle ; basal joint of tarsi sharply dentate above ; pygidium and pro- 

 sternum as in Oryctes. 



This genus differs from Cyphonistes in general facies, owing to 

 the cephalic horn of the male being tubercular, and the prothorax 

 simple, but the main distinctive character is the shape of the mentum 

 which is not strangulate nor grooved laterally on the outer side for 

 the insertion of the antennae. 



It includes only one species, P. corniculatus , which is found under 

 the small mounds made by a Termes (spec, indeterm) . Its larva is 

 also found there in company with that of the Cetonid Trichostetha 

 capensis, and I have ascertained that it feeds upon the material of 

 which the more or less conical base of the termite nest is made.

Handb. d. Entom., v., 1847, p. 214. 

 Chestnut-brown on the upper and under sides, glabrous above, 

 densely hairy on the pectus ; clypeus triangular, sinuate laterally 

 near the base and with the straight apical part reflexed but not 

 dentate, maxillae projecting very much beyond the clypeus, bi- 

 dentate on each side, the inner tooth being smaller and rounded, 

 the outer one diverging, sharp and reflexed, genae sub- semicircular, 

 distinct, in both sexes there is a frontal ledge produced in the centre 

 into a small yet distinct tubercle emarginate at tip ; prothorax some- 

 what convex, simple in both sexes, very distinctly marginate all 

 round, strongly plicate in the anterior part foi' two-thirds of the 

 length, but with a broad basal and lateral smooth space ; scutellum 

 strongly punctured at middle ; elytra convex, not very sinuate
