Illinois, South Carolina and Florida; four specimens, in which there is 

 no sexual difference; the head is punctured and convex, with a very small 

 frontal callus. The form is stouter, the size much smaller, and the punc- 

 tures coarser than in our allied species; the pubescence is sparse, long and 

 erect. Length l.f) mm.; .06 inch. 



10. P. cariniceps, n. sp. 



Rather slender, cylindrical, blackish piceous shining, pubescence fine, 

 sparse and erect. Head ((^) finely punctured, opaque, with two very deep 

 excavations, extending almost to the front margin, and separated by a nar- 

 row, elevated, longitudinal carina; eyes deeply and narrowly emarginate. 

 Prothorax longer than wide, anterior half densely asperate, separated from 

 the posterior halfby a shallow, transverse impression; posterior half shining, 

 distinctly but not densely punctured, smooth dorsal line not elevated, base 

 distinctly margined. Elytra strongly punctured, punctures arranged partlj' 

 in rows; declivitj' strongly retuse, with a few little asperities on the highest 

 part of the elevation; suture slightly impressed, and marked with a row of 

 punctures as far as the declivity, where it becomes smooth and deeply im- 

 pressed, concavity smooth, broader at the tip. Pygidium scarcely visible 

 from beneath; fifth ventral not longer than fourth, broadlj^ rounded behind. 

 Antennpe and legs yellow-brown; club transversely annulated with curved 

 sutures; outer part of funicle indistinctly divided into four parts; tibiae with 

 two or three feeble teeth towards the tip. Length 2.5 mm. ; .10 inch. 



Detroit, Michigan; Messrs. Hubbard and Schwarz; one (^. The pubes- 

 cence has probably been partly abraded. The peculiar sculpture of the head 

 induces me to believe that the reference of the supposed 9 under P. carin- 

 ulatus may be erroneous, and that it probably indicates a distinct species, 

 which, however, cannot be correctly defined from want of sufticient mate- 

 rial. 



11. P. fossifrons, n. sp. 



Of the same form and color as the last, but the head (rP) has one round 

 and very deep fovea, and the eyes are not emarginate. Prothorax longer 

 than wide, asperate on the front half, strongly and deeply punctured be- 

 hind; smooth dorsal line narrow, distinctly elevated towards the middle of 

 the disc. Elytra rather finely and not regularly punctured; pubescence long, 

 erect; sutural stria visible, deeply excavated behind; declivity slightly re- 

 tuse, with two indistinct cusps. Antenna^ and legs yellow-brown, of the 

 same form as in the last. Length 3.3 mm.; .09 inch. 



Vancouver Island; Messrs. Matthews; two (^ specimens. This species 

 resembles P. carinulatus in sculpture, and in the form of the eyes; but the 

 excavation of the head is smaller, deeper and more pit-like; the posterior 

 callosity of the elytra is less prominent; the cusps are small and feebly de- 

 veloped, and finally the pygidium is much less inflexed, so as to be hardly 

 visible from l)eneath.
