joint of the male. From obscurus it may be known by its coarser 

 pronotal punctuation, and more robust and compressed antennae 

 with more strongly obconical joints and with longer third joint in 

 the male, and finally from perforatus, by its longer, rather less 

 coarsely and more evenly punctate pronotum, much shorter antennae 

 and relatively narrower elytra. 



10 H. perforatus n. sp. — Oblong, moderately convex, polished through- 

 out, dark piceous-brown, the legs and antenna? slightly paler and more ferru- 

 ginous ; pubescence rather long, coarse, semi-erect, pale, moderately dense 

 and conspicuous. Head coarsely, deeply but rather sparsely punctate, the 

 eyes rather large, separated by about their own width in the male ; antennae 

 about one-half as long as the body, filiform, rather stout, the joints feebly 

 obconical and more than twice as long as wide. Prothorqx fully three-fourths 

 wider than long, the apex broadly, strongly arcuate and continuous in curva- 

 ture with the sides, which become parallel and feebly arcuate in basal half, the 

 angles right, not rounded ; base transverse, the sinuations broad and feeble ; 

 disk obsoletely impressed along the middle, the basal fovese nearly obsolete, 

 the surface very coarsely, deeply punctate, the punctures sparse, separated 

 generally by nearly twice their own diameters. Elytra a little more than four 

 times as long as the prothorax and about one -fifth wider, obtusely ogival in 

 less than apical third ; sides parallel and nearly straight, the humeri nar- 

 rowly, abruptly rounded to the prothorax and exposed at base ; disk with 

 rather strongly impressed series of somewhat coarse, deep punctures, the 

 intervals feebly convex, finely, sparsely, confusedly and rather unevenly 

 punctured. Abdomen sparsely, finely punctate. Legs slender, the basal joint 

 of the hind tarsi a little longer than the remainder. Length 7.5 mm. ; width 

 2.8 mm. 



Pennsylvania ; Indiana ; North Carolina. 



The three specimens before me are males ; in this sex the third 

 antennal joint is fully two-thirds as long as the fourth. 



Although belonging to the same division of the genus as obscu- 

 rus, the present species differs greatly in its extremely coarse pro- 

 notal punctuation, and in having the elytra abruptly and distinctly 

 wider than the prothorax. 



11 H. Clirticollis n. sp. — Oblong-oval, rather depressed, black with a 

 piceous tinge throughout, the tarsi, antennae near the base and palpi paler, 

 rnfescent ; surface highly polished, the pubescence coarse, pale, sparse and 

 unusually long. Head coarsely, deeply, rather sparsely punctate, the eyes 

 moderate, separated by scarcely their own width in the male and but slightly 

 more in the female, the antennae slender, filiform, scarcely perceptibly com- 

 pressed, rather more than one-half as long as the body, the joints strongly 

 obconical, twice as long as wide, the third very short in the male and scarcely 

 one-half as long as the fourth. Prothorax short, fully four-fifths wider than
