very obviously longer than wide, parallel, the impression extending 

 through basal third ; abdomen as \x\ perte?mis. Male with two small 

 rounded and projecting median lobes and three sinuses at the apex 

 of the fourth ventral, the fifth with a small tubercle opposite each of 

 the lateral sinuses, and a small setigerous tubercle opposite the 

 median and rather deepest sinus; sixth segment broadly and strongly 

 concave almost throughout its width, the seventh convex and longi- 

 tudinally carinulate; median trochanters with a small posterior tooth. 

 Length, i.o mm.; width, 0.25 mm. ( (^ , $ ). Pennsylvania (Westmore-

3. Form rather stouter and less parallel than in the preceding species, 

 shining, dark testaceous, the elytra infuscate ; pubescence rather 

 inconspicuous ; head but little wider than long, the sides feebly 

 converging basally, the eyes at much more than their own length 

 from the base, the latter broadly sinuate ; occiput with a fine axial 

 impression as usual ; surface finely, sparsely and equally punctate 

 throughout ; foveae large, elongate, deep, mutually separated 

 rather more than either from the eye, their posterior part pubescent ; 

 transverse frontal pit deep, polished and irapunctate ; antennae as in 

 filiformis; prothorax as long as wide, narrower than the head, 

 minutely, equally punctate like the latter, the foveae nearly similar ; 

 transverse sulcus similarly obsolete ; converging sides each with a 

 very small tooth at the fovea, not distinctly observable in filiformis^ 

 though slightly evident in pertenuis ; elytra obviously shorter than 

 the head and prothorax, distinctly wider than the former, parallel, 

 with feebly arcuate sides, evidently longer than wide, the deep 

 impression obsolete at basal third ; abdomen parallel, much narrower 

 than the elytra and not quite so long, the segments equal as usual, 

 the two basal feebly impressed medially at base. Male with much 

 feebler sexual characters, the fourth ventral unmodified, the fifth very 

 short medially and scarcely half as long as the fourth, not modified 

 except perhaps a very small feeble median tubercle ; sixth as long 

 as the fourth, broadly, subangulaily emarginate throughout the 

 width, its surface flattened medially ; seventh not convex, but flat or 

 feebly, unevenly impressed transversely, longitudinally carinulate, 

 broadly angular anteriorly, broadly rounded throughout the width at 

 apex. Length, 0.9 mm.; width, 0.25 mm. {$). Pennsylvania
