Dark reddish brown to brownish black, the palpi, antennae, and 

 legs paler. 



Head with front coarsely, irregularly punctate, sparsely clothed 

 with long, inconspicuous, semierect hairs, obliquely deflexed at an- 

 terior margin; clypeus flat, coarsely, shallowly punctate, sparsely 

 clothed with long, inconspicuous, semierect hairs, with two to six 

 small, more or less distinct, tubercles along anterior margin. Antennal 

 club densely clothed with short, recumbent, yellowish hairs, with a 

 few long, erect hairs intermixed, the segments transverse, oval. 



Pronotum strongly, uniformly convex, widest near basal third, with 

 a vague, longitudinal groove at middle of disk ; sides with a row of small 

 teeth on each side near posterior angles; surface sparsely clothed with 

 short, inconspicuous, recumbent hairs, densely, coarsely punctate at 

 sides, coarsely imbricate at middle on basal half, the imbrications broad 

 and broadly rounded at apices, and with transversely arcuate rows of 

 elevated teeth at middle on apical half, the teeth obtusely rounded at 

 apices and distinctly separated from one another, except the two 

 median ones on anterior margin, which are nearly contiguous. 



Elytra at base subequal in width to pronotum near basal third ; sides 

 parallel, conjointly, broadly rounded at apices; surface coarsely, 

 densely, irregularly punctate, sparsely clothed with short, recurved. 

 yellowish hairs, which are about as long as intervals between the 

 punctures on anterior part of disk; apical declivity rather densely 

 clothed with long, recumbent, yellowish hairs, with one or two more 

 or less distinct, small, erect tubercles on each side near top of declivity, 

 densely, coarsely, continently punctate in females, nearly smooth and 

 finely, sparsely punctate along sutural margins in males. 



Body beneath sparsely clothed with long, recumbent, yellowish 

 hairs: abdomen finely, indistinctly punctate, and finely, densely 

 granulose. 



Length 4-5 mm., width 1.5-1.7 mm. 



Type locality. — Xone given, but probably York County. Pa.
