9. P. pulicarius. CrypturgusXpul. Zimin., Trans. Am.Ent. Soc. 1868, 

 144. 



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

 no sexual difterence; 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 1.5 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 partly 

 in rows; declivity 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, broadly rounded behind. 

 Antennae and legs yelloAv-brown; club transversely annulated with curved 

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

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



Detroit, Michigan; Messrs. Hubbard and Schwarz; one (j^. 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. airin- 

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

 w^hich, however, cannot be correctly defined from want of sufficient mate- 

 rial. 



11. P. fossifrons, n. sp. 



Of the same form and color as the last, but the head {(^) 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 2.3 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 beneath.
