very large aud deep throughout ; occiput impressed at the middle ; antennse 

 nearly as long as the head and prothorax, the club gradual in formation ; 

 ninth and tenth joints moderately transverse, the fifth slightly larger than the 

 other joints of the funicle. Prothorax smooth and subim punctate, strongly 

 convex, fully % wider than long, widest near apical third, where the sides are 

 more strongly rounded, thence moderately convergent, broadly arcuate and 

 but slightly uneven to the base ; neck about }4, the maximum width ; discal 

 fovea rather small, elongate-oval in form, the lateral large and deep, the con- 

 necting sulcus strongly biarcuate, coarse and deep toward the middle. Elytra 

 nearly quadrate, % longer and }-^ wider than the prothorax, the sides parallel 

 and broadly arcuate ; surface moderately convex, subimjiunctate, the discal 

 stria short, not extending to the middle. Abdomen narrower than the elj^tra, 

 the sides straight and parallel ; dorsals equal in length, the carinse of the first 

 two straight, fine, strongly divergent and separated by about I4 the total 

 width. Legs moderately short and thick, the third joint of the hind tarsi 

 about as long as the two basal joints combined, with the claw fully }-^ as long 

 as the entire tarsus. Length 1.1 mm. ; width 0.35 mm.

In the male type the fourth ventral seems to be unmodified, the 

 filiu with a small, deep and circul'arly rounded anterior emargina- 

 tion, but otherwise scarcely modified, the sixth with a broad, 

 subluuate and feeble impression, slightly tumid anteriorly near 

 its extremities ; the seventh is rhomboidal, very convex, minutely 

 and sparsely punctate and with a fine, strongl}^ elevated and some- 

 what asymmetric median carina. The female difiers but little, ex- 

 cept that the head is distinctly' narrower than the prothorax. 



This species, which is one of the smallest of the genus, diflfers 

 from hudsonicus in its larger e^'es, more convergent tempora, 

 smooth pronotum with short and non-sulciform discal pit, nar- 

 rower bodily form, and in many other characters. 



P. iniperfectiis n. sp. — Eather large and somewhat stout, convex, elon- 

 gate, dark rufo-testaceous throughout, impunctate and polished, the pubescence 

 moderately long and coarse and rather sparse. Head scarcely as wide as the 

 prothorax, the eyes only moderately large and not very prominent, shorter 

 than the tempora, which are distinctly convergent and broadly arcuate behind 

 them ; occiput convex, very obsoletely impressed at the middle ; fovete deep, 

 separated by nearly J3 the total width or twice the distance from either eye, 

 the sulcus large, very deep and parabolic ; supra-orbital edges rather distinct, 

 somewhat rugose ; antennse not quite as long as the head and prothorax, the 

 second joint much shorter and narrower than the first, three to eight small and 

 moniliform, eight and nine wider, eleventh still wider and as long as the pre- 

 ceding three combined. Prothorax % wider than long, widest and promi- 

 nently rounded at apical third, the sides thence convergent and broadly arcuate 

 to the base, minutely emarginate at the fovese ; disk convex, the discal fovea
