262 H. C. FALL. 



Pubescence of upper surface recumbent. 



Black, more coarsely and more uniformly punctate; joints of antenna! club 



more strongly produced internally 1. dresdensis. 



Brown, more finely punctate, with rather inconspicuous larger punctures 



sparsely placed 2. integer. 



Pubescence erect 3. setulosum. 



1. S>. dresdensis Herbst. — Oval, moderately elongate, convex ; black 

 tibise more or less rufous, tarsi and antenna? paler; surface shining, with fine 

 recumbent grayish pubescence. Head finely punctate, the punctures separated 

 by from one to two times their own diameters ; eyes moderate, scarcely larger in 

 the males, distant on the front by nearly twice their vertical diameters. An- 

 tennae rufo testaceous, the basal joint darker; fourth joint a little more promi- 

 nent internally; joints 8 and 9 moderately emarginate on their apical edge in 

 the female, more elongate and emarginate so deeply as to become branched in 

 the male. Terminal joint of maxillary palpus slender, more than twice as long 

 as wide, slightly widening toward the apex; last joint of labial palpi broadly 

 triangular, apex transversely truncate and minutely sinuate. Prothorax short, 

 sides strougly convergent and uearly straight, side margin narrower, not visible 

 from above; punctuation nearly as fine as that of the bead, nearly uniform in 

 size, the punctures separated by from one to two times their own diameters. 

 Elytra rather more than three times as long as the prothorax, parallel to beyond 

 the middle; punctuation nearly uniform, distinctly coarser and usually closer 

 than that of the prothorax, but somewhat variable; sides with two suhmarginal 

 strise, the outer entire, the inner sometimes a little abbreviated or more faintly 

 impressed at apex. There is usually a well marked trace of an inner third stria 

 immediately behind the humeral umboue. Metasternum deeply longitudinally 

 sulcate throughout its length and usually with a short oblique impression on 

 each side the median sulcus; punctuation very sparse and fine at middle, denser 

 and coarser laterally, especially in front, where the punctures are obviously 

 though not very conspicuously unequal in size. Abdomen more finely and 

 evenly, and less closely punctate than the metasternum. Length 2.5-3 mm. 



This rather common species occurs throughout the northern 

 United States and Canada as far west as Montana (Kalispell, 

 Wickham) and south to Virginia and Missouri. It was described 

 by LeConte under the name pallicomis in Austin's list of the Cole- 

 optera of Mt. Washington, but I am quite unable to separate it 

 from European specimens of dresdensis, a species common and wide 

 spread in northern and middle Europe. 



2. D. integer Fall. — Similar in form to dresdensis; brown, with legs and 

 antennae paler; pubescence ochreous in color, fine, recumbent. Punctuation 

 finer throughout than in dresdensis, the punctures of the upper surface incon- 

 spicuously, and of the metasternum distinctly, varying in size. Fourth joint of 

 antennae not prominent internally, the joints of the club not as wide as in dres- 

 densis, the eighth and ninth feebly or scarcely emarginate apically, the latter 

 longer than wide. Suhmarginal stria? of elytra a little finer than in dresdensis,
