8 Memoirs on the Coleoptera 



form and structure nearly as in the preceding; prothorax similarly 

 widest before the middle but less inflated anteriorly, so that the 

 sides are less strongly rounded; elytra a little longer, more than 

 one-half longer than wide in the male, as usual a little longer in the 

 female, the broad subapical oblique sinus a little more evident; 

 punctures of the alternate intervals more numerous but as usual 

 sparse apically; under surface blackish-piceous. First three joints 

 of the anterior male tarsi broader than in the preceding, the third 

 joint less than one-half longer than wide and not nearly twice as 

 long as wide as it is in hypoliihus. Length (cf ? ) 14.0-15.0 mm.; 

 width 5.1-5.5 mm. Ontario. Levette collection, .ontariensis n. sp. 

 3 — Form narrow, elongate, more depressed than in the preceding group, 

 piceous-black, shining, the legs nearly black; head relatively larger, 

 nearly as wide as the prothorax, strongly rhomboidal, with moderate 

 but prominent eyes, with the usual slender pale palpi, the antennae 

 three-fifths as long as the body; prothorax smaller than usual, 

 slightly elongate, inflated anteriorly, with the sides more evidently 

 sinuate posteriorly and the angles similarly broadly rounded, the 

 smooth and deeply concave fovese traceable fully to the middle; 

 margins similarly strongly reflexed; transverse impressions fine, 

 deep; median stria deep but obliterated submedially; base slightly 

 narrower than the apex; elytra nearly twice as long as wide, almost 

 twice as wide as the prothorax, the sides gradually rounding basally, 

 the apex rapidly and narrowly oblique, distinctly sinuate; striae 

 smooth as usual, deeply impressed, the scutellar parallel; punctures 

 bearing rather long fulvous setae. Male with the first three anterior 

 tarsal joints narrow, parallel, rapidly narrowed at base, the third 

 one-half longer than wide; lateral groove of the posterior tarsi 

 deep; abdomen as in hypolithus. Length (cT 9 ) 11. 5-13.0 mm.; 

 width 3.8-4.2 mm. North Carolina (Black Mts.), — Beutenmiiller. 



Four examples gracilentus Beut. 



Form much less narrow, larger in size, similar in coloration and in the 

 shining lustre; head similarly elongate though wider and less 

 strongly rhomboidal; front with two small indentations transversely 

 placed between the eyes; antennae ferruginous, even longer than in 

 the preceding; prothorax larger, much wider than the head, barely 

 as long as wide, the strongly reflexed sides more broadly rounded, 

 less sinuate posteriorly; surface nearly similar, the finer median 

 stria less evidently subinterrupted medially; base much wider, 

 fully as wide as the apex; apical angles more obtusely rounded; 

 elytra oval, two-thirds longer than wide, not quite twice as wide as 

 the prothorax, subinflated posteriorly, the sides more rounded 

 basally than in the preceding, the rather obtuse apex, sinus and 

 fulvous setae nearly similar. Length ( 9 ) 14.5 mm.; width 5.15 mm.
