7 H. obesus n. sp. — Broadly oblong-oval, rather strongly convex, polished 

 throughout, piceous-black, the abdomen black ; legs piceous, the tarsi paler; 

 antennae rufo-fuscous ; pubescence moderate in length, rather sparse, coarse, 

 pale in color. Head sparsely, somewhat coarsely punctate ; eyes moderate, 

 separated by a little less (male), or a little more (female), than their own 

 width ; antenna? slender, filiform, two-fifths as long as the body, the joints 

 nearly parallel, gradually slightly shorter toward apex, the third a little 

 shorter than the fourth in the male, slender, the fourth three times as long as 

 wide. Prothorax two-thirds to three-fourths wider than long, the apex two- 

 thirds as wide as the base, broadly arcuate, the sides parallel and feebly 

 arcuate in basal half, thence rather strongly convergent and arcuate to the 

 apex ; basal angles distinctly obtuse and blunt ; base transverse, the sinua- 

 tions rather broad and feeble ; disk scarcely at all impressed, moderately 

 coarsely, strongly, sparsely punctate. Elytra from three and one-half to nearly 

 four times as long as the prothorax, toward base barely perceptibly wider 

 than the prothorax, a little more distinctly so posteriorly, rather broadly, 

 obtusely ogival at apex ; sides feebly arcuate ; disk with feebly impressed 

 series of small, deep, close-set punctures, the intervals finely, rather sparsely 

 punctate in the female, very sparsely so in the male. Abdomen finely, sparsely 

 punctate throughout. Legs slender ; basal joint of the hind tarsi much longer 

 than the remainder. Length 6.7-8.0 mm. ; width 3.2-3.5 mm. 



New York. 



The broadly oval form and more slender, filiform antennae of this 

 species will serve to distinguish it from pilosus, to which it is rather 

 closely allied. The third antennal joint of the male is slightly 

 shorter, and the outer joints decrease more conspicuously in length, 

 than in pilosus, and the eyes in the same sex are distinctly larger. 



8 H. pilosus Melsh.— Proc. Ac. Phil.. Ill, 1846, p. 58.— Rather broad, 

 oblong-oval, moderately convex, black or piceous black throughout, the abdo- 

 men, legs and antennae concolorous, the tarsi paler, rufescent; surface polished 

 throughout; pubescence moderate in length, pale, coarse, rather sparse but 

 conspicuous. Head coarsely, deeply, somewhat sparsely punctate, the eyes 

 moderate, separated by from one-third to one-fourth more than their own 

 width ; antenna? slender, filiform, two-fifths as long as the body, the joints 

 quite distinctly obconical, more than twice as long as wide, the third and 

 fourth long, exactly equal in both sexes. Prothorax three-fourths wider than 

 long, the apex broadly arcuate, three-fourths as wide as the base, not evenly 

 continuous with the sides, the latter convergent and almost evenly arcuate 

 from base to apex in both sexes ; basal angles right and distinctly blunt ; 

 base transverse, the sinuations rather broad and feeble ; disk scarcely at all 

 impressed, quite coarsely, deeply, strongly punctate, the punctures separated 

 by two to three times their diameters in the male, rather closer in the female. 

 Elytra nearly four times as long as the prothorax, and, at the middle, slightly 

 wider, rather obtusely rounded behind, the sides parallel and just visibly
