The only variation observed is in one specimen in which the median 

 line of the thorax is slightly impressed. 



Occurs in Canada, New York, Pennsylvania and Virginia. 



in. aurtax n. sp. — Form moderatrly elongate, gradually narrower behind, 

 piceous, feebly shining, sparsely clothed with short fulvous pubescence ; elytra 

 pale brown ; antennse and legs bright rufo-testaceous ; auteunie two-thirds the 

 length of the body, strongly serrate from the fourth joint ; head coarsely, densely 

 and roughly punctate, vertex with three vague impressions arranged in a trian- 

 gle ; clyi^eus slightly wider at base than the space between it and the eye ; pro- 

 thorax a little wider than long, sides parallel, rounded only at the front angles, 

 hind angles not divergent, distinctly carinate, disc convex, densely and rather 

 coarsely punctured, a moderately deep median impression extending from the 

 base to the middle and two vague oblique impressions each side ; anterior sup- 

 plementary carina short, one-fifth the length of the thorax, oblique, posterior 

 carina extremely short ; juxta-sutural sulcus deep and smooth, slightly wider 

 posteriorly, the outer carina entire, extending to the hind angles ; elytra as wide 

 as the thorax, narrowing at apical third only, disc vaguely striate, moderately 

 densely punctured, rather less dense than on the thorax, a little finer near the 

 apex, somewhat rugose on the basal depression; body beneath rather coarsely 

 and closely punctate, more coarsely on the prosternal parapleural ; metasternal 

 episterna very narrow, slightly broader posteriorly ; posterior coxal jilates niucli 

 narrower externally; fourth tarsal joint dilated and lobed beneath, claws dilated 

 at base. Length .14 inch ; 3.5 mm. 



Having seen but one specimen of this species it is impossible to say 

 with certainty that the pale reddish brown color of the elytra is a 

 constant character. It is, however, remarkable among our species 

 in having both the supplementary carinas very short and the median 

 depression of the thorax rather deep.

 hind, piceous, feebly shining, sparsely clothed with very short fulvous pubes- 

 cence; antennae reddish brown, the basal joint darker, half as long as the body, 

 feebly serrate; head coarsely and moderately densely punctured, front slightly 

 concave ; clypeus at base narrower than the distance from it to the eye ; thorax 

 as long as wide, sides parallel behind, arcuate at apical third, disc moderately 

 convex, coarsely not densely punctured, a finely impres.sed line from the base to 

 the middle, hind angles obtusely carinate ; anterior supplementary carina 

 straight, extending nearly one-third to base, posterior carina extremely short; 

 juxta-sutural sulcus deep, punctured posteriorly, the outer carina extending 

 barely more than one-half from the apex ; elytra substriate, surface coarsely and 

 rather closely punctured, the punctures coarser than on the thorax and quite 

 rough at base ; body beneath rather densely punctured ; prosternal episterna 

 narrow, slightly broader posteriorly ; hind coxal plates narrower externally ;
