io8 MEMOIRS ON THE COLEOPTERA 



surface black, the legs rufous; epipleura pale; head two-thirds as 

 wide as the prothorax, with narrow and rather deep sulci and large 

 but only moderately prominent eyes; antennae fuscous, in part tes- 

 taceous basally; prothorax two-fifths wider than long, the sides 

 rather strongly rounded before the middle, broadly and distinctly 

 sinuate basally, the angles sharp, right or rather more; impressions 

 very feeble; stria not entire and fine, but deeply and sharply im- 

 pressed; foveae large, linear at the bottom, the strong carina nearly 

 a third the total length; elytra oblong-oval, barely one-half longer 

 than wide, a third to two-fifths wider than the prothorax; striae 

 coarse, more or less impressed, the punctures close-set, rather coarse 

 and conspicuous toward base; foveae near basal and apical third. 

 Length (cf 9 ) 3.4-4.2 mm.; width 1.2-1.6 mm. Pennsylvania, New 

 York, Indiana and Iowa. [Bemb. variegatum Lee. nee Say]. 



patruele Dej. 



Antennae not so long, much shorter than the elytra, the medial joints 

 about twice as long as wide; surface less convex, form narrower, the 

 striae finer and less impressed 3& 



38 Form oblong, feebly convex, in color and lustre nearly as in patruele, 

 but with the knees somewhat darker; elytra with the whitish macu- 

 lation, covering almost as much area as the black ground, more 

 sharply defined and with the pale lines composing the fasciae more 

 defined by the black striae than usual, disposed as in patruele; head 

 similar but inserted almost to the very large eyes; antennae blackish, 

 red toward base only on the under surface of the joints; prothorax 

 one-half wider than long, the sides broadly, evenly rounded to a 

 short feeble sinuation just before the sharp basal angles; impressions 

 feeble and very indefinite, the stria extremely fine; foveae and carina 

 nearly as in the preceding; elytra parallel, more obtusely rounded 

 at tip, slightly longer, two-fifths wider than the prothorax; striae 

 rather fine, barely at all impressed, distinctly punctate to near the 

 apex; third interval much wider than the others, the foveae before 

 basal and near apical third. Length (cf ) 3.6 mm.; width 1.35 mm. 

 Wisconsin (Bayfield), Wickham graphicum n. sp. 



Form less depressed and not quite so narrow, the elytra with more re- 

 stricted maculation, black, shining, the head feebly alutaceous; ely- 

 tra with small spots, a dash on the fifth interval at base, two small, 

 as usual, before and behind the fovea on the third, the short anterior 

 fascia feeble, with a long streak on the eighth interval, the posterior 

 fascia narrow, irregularly biarcuate, the apical pale spots composed 

 each of three dashes; head as in graphicum but with less prominent 

 eyes, the antennae similar; prothorax one-half wider than long, the 

 evenly rounded sides less strongly arcuate, becoming very gradually 

 and only just visibly sinuate toward the angles, which are slightly 

 obtuse, though not rounded; surface throughout nearly as in graphi- 

 cum; elytra shorter, barely one-half longer than wide, obliquely 

 ogival in apical third, two-fifths wider than the prothorax, almost 

 similarly striate and punctate, but with the third interval only
