150 Coleopterological Notices, III. 



entire body sometimes darker, piceous ; pubescence extremely short and rather 

 sparse. Head feebly, evenly convex, densely punctate, rather shining; eyes 

 small ; antennae filiform, about one-half as long as the body, with the third 

 and fourth joints elongate and equal in both sexes. Prothorax nearly twice 

 as wide as long, the apex rather wide, fully two-thirds as wide as the base, 

 feebly arcuate ; base transverse, very broadly and feebly arcuate toward the 

 middle ; sides rounded toward base, convergent and straighter toward apex ; 

 basal angles slightly obtuse and narrowly rounded ; disk finely, deeply and 

 more or less densely punctate, the interspaces sometimes nearly as wide as 

 the punctures ; basal fovere almost completely obsolete. Elytra four times as 

 long as the prothorax, near the middle about one-fourth wider, rather abruptly 

 and narrowly rounded at apex ; disk finely and deeply but quite sparsely 

 punctate, with only the vaguest traces of impressed strise except the two 

 sutural, which become very pronounced toward apex. Under surface polished 

 and rather sparsely, finely punctate throughout. Legs moderate in length, 

 slender, nearly as in sericea. 



Mule. — Eyes separated by nearly three times their width, not appreciably 

 differing in the female. 



Length 5.0-5.8 mm. ; width 2.1-2.8 mm. 



Canada ; Lake Superior ; North Carolina. 



A widely diffused and common northern species, distinguishable 

 by its rather sparse punctuation and the sides of the prothorax more 

 strongly rounded toward base, so that in some specimens the disk 

 is distinctly widest before the base. The male is notably narrower 

 than the female. The terminal joint of the maxillary palpi is broad, 

 and the outer side is scarcely longer than the apex. 



The single male which I took in North Carolina is decidedly 

 shorter and broader than another male taken in Rhode Island, and 

 the sides of the prothorax near the base much less rounded, in fact 

 almost straight and parallel; it may possibly be a variety. 



The disk of the prothorax is less convex toward the sides than 

 in the species allied to sericea, and there are generally two feebly 

 impressed discal fovea? and a feeble median impression near the base. 



I* moilticola n. sp. — Elongate-oval, moderately convex, dark piceous- 

 brown throughout and shining, the prothorax more rufous ; pubescence very 

 short, comparatively sj^arse on the elytra. Head small, not one-half as wide 

 as the prothorax, broadly impressed near the epistoma, finely but sti'ongly 

 punctate, the punctures slightly separated ; eyes small, separated by fully 

 three times their width in the female ; antennae long, very slender, the third 

 joint four-fifths as long as the fourth. Prothorax about four-fifths wider than 

 long, broadly but distinctly arcuate at apex, the curvature nearly continuous 

 posteriorly along the sides, the latter becoming parallel near the base, the 

 basal angles not rounded ; base transverse, thesinuations distinct ; disk rather
