 York, Pennsylvania, Indiana, Missouri, Iowa and Lake Superior

sinuatus Dej. 



Body somewhat similar in form, coloration and lustre but much smaller 

 and with more anteriorly inflated prothorax, the sides of which are 

 more sinuate basally; head nearly similar but with still more 

 prominent eyes; antennae similar in coloration but not quite so 

 long, less than half as long as the body, the individual joints notably 

 shorter; prothorax a little shorter than wide, as in sinuatus through- 

 out, except that the sides are more inflated and more strongly 

 rounded anteriorly, with the basal sinus longer and a little deeper, 

 but with the sharp tips of the angles not quite so prominent; sides 

 strongly refiexed, feebly punctulate, the large deep basal fovese 

 distinctly punctate; apical angles somewhat more broadly and 

 obtusely rounded; elytra subsimilar in general form, two-thirds 

 wider than the prothorax, the apical sinus a little less shallow; 

 striae not quite so deep but similarly punctate at the bottom; 

 second joint of the anterior male tarsi of a very different outline, 

 more oblong, with the sides more nearly parallel and much less than 

 one-half longer than wide; hind tarsi with the outer sulcus deep. 

 Length (d^) 9.2-9.5 mm.; width 3.2-3.5 mm. Lake Superior 

 (Bayfield) and Manitoba (Winnipeg), — 'Wickham. . .turbidus n. sp. 



Body still smaller in size, rather more ventricose, similarly deep black 

 and polished, the legs black but pallescent toward the coxae; head 

 fully three-fourths as wide as the prothorax, with moderate eyes, 

 the frontal parts before them not much prolonged; impressions 

 deep, dilated inwardly at the middle; palpi black, with pallid tip; 

 antennae rather more than half as long as the body, black, the 

 pubescence gray, the third joint much longer than the fourth; 

 prothorax nearly as long as wide, much narrower than in the pre- 

 ceding and not anteriorly inflated, parallel, the sides broadly and 

 moderately arcuate, becoming gradually very feebly sinuate toward 

 the angles, which are obtuse but with sharply defined and slightly 

 prominent tips; margins strongly refiexed, only a little more so 

 basally, the gutter punctulate to the apex, the punctures more wide- 

 spread, coarser and conspicuous through the foveal region, the 

 foveae large, broadly impressed, with a very short linear incised 

 part basally; impressions deep, especially the anterior, the stria 

 broadly impressed, basally abbreviated; base even somewhat wider 

 than the apex; elytra fully one-half longer than wide, three-fourths 

 wider than the prothorax, oblong-oval, the sides rather arcuate, 

 more rounded at base; subapical sinus rather long and feeble; 

 striae moderately coarse, feebly impressed, the punctures along the 

 bottom very fine but evident; intervals feebly convex, the three 

 punctures moderate. Length (9) 9.2 mm.; width 3.4 mm. Iowa 

 (Iowa City), — Wickham iowanus n. sp. 



7 — Pronotum with coarse, deep and very conspicuous transverse rugae. 

 Body piceous-brown in color throughout, shining, the elytra (9) 

 very feebly alutaceous; head elongate, two-thirds as wide as the
