Elytra slightly wider than pronotum at base, about equal in width 

 at base and apical third, broadly, arcuately constricted in front of 

 middle, and arcuately narrowed from apical third to the tips, which 

 are separately, broadly rounded, and feebly, irregularly serrulate; 

 sides of abdomen slightly exposed above ; disk feebly convex, vaguely, 

 longitudinally depressed, sutural margins elevated posteriorly, and 

 with broad, shallow basal depressions; surface densely imbricate- 

 granulate. 



Abdomen beneath coarsely, densely punctate, and finely granulose 

 on the basal segments, becoming more sparsely and finely punctate 

 toward the apex, the punctures more or less connected transversely 

 by fine, sinuate lines, and uniformly, rather sparsely clothed with 

 short, recumbent, whitish pubescence; first and second segments 

 feebly, broadly, longitudinally flattened, but not densely pubescent; 

 vertical portions of the segments not conspicuously pubescent; 

 pygidium sparsely, coarsely punctate, but not longitudinally carinate. 

 Prosternum coarsely, densely granulose, somewhat rugose, and 

 sparsely clothed with short, inconspicuous hairs; prosternal lobe 

 broad, strongly declivous, and vaguely, broadly emarginate in front ; 

 prosternal process rather narrow, the sides parallel to behind the 

 coxal cavities, then obliquely narrowed to the apex, which is acute. 

 Posterior coxae with the posterior margin broadly, arcuately emar- 

 ginate, and the exterior angle rectangular. Tibiae slender, the an- 

 terior pair slightly arcuate, and all three pairs armed with a long 

 tooth on inner margin at apex. Posterior tarsi slightly shorter than 

 tibiae, and the first joint as long as the following three joints united. 

 Tarsal claws similar on all feet, cleft near the middle, the outer tooth 

 acute at apex, the inner one slightly broader, turned inward, and 

 the tip sometimes touching that of the opposite side. 



Length, 4.25 mm. ; width, 1 mm. 



Female. — Differs from the male in having the front of head 

 broader, more convex, occiput slightly grooved, the lateral margins 

 more parallel to each other, the surface aeneous, with a cupreous 

 tinge, and more sparsely pubescent behind the epistoma ; pronotum 

 more uniformly aeneous ; prosternum more sparsely punctured ; first 

 two abdominal segments convex at middle, and the tibiae without a 

 distinct tooth on inner margin at apex. 



Redescribed from the type (male) in the collection of J. N. Knull. 



Type locality. — Framingham, Mass.
