Abdomen beneath finely, rather densely punctate, becoming some- 

 what rugose on the basal segments, and sparsely clothed with moder- 

 ately long, recumbent, whitish pubescence ; first and second segments 

 feebly flattened at middle, and clothed with a longitudinal series of 

 densely placed, long, whitish hairs ; vertical portions of the segments 

 not conspicuously pubescent; pygidium sparsely, coarsely punctate, 

 with the median carina feebly elevated, but not projecting. Prester- 

 num densely, finely punctate, and densely clothed with a longitudinal 

 series of long, fine, erect hairs at the middle; prosternal lobe rather 

 wide, slightly declivous, broadly rounded, and subtruncate or feebly 

 emarginate in front; prosternal process rather narrow, the sides 

 nearly parallel to behind the coxal cavities, then obliquely narrowed 

 to the apex, which is acute. Posterior coxae with the posterior mar- 

 gin broadly, arcuately emarginate, and the exterior angle nearly 

 rectangular. Tibiae slender, straight, and armed with a short tooth 

 on inner margin at apex. Posterior tarsi about as long as the tibiae, 

 and the first joint as long as the following 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, 5.25 mm. ; width, 1.25 mm. 



Female. — Differs from the male in being more robust, front of 

 head aeneous, slightly more convex, and not densely clothed with 

 long, white pubescence behind the epistoma; marginal carinae of 

 pronotum more strongly sinuate; prehumeral carinae not quite so 

 sharply elevated; prosternum more sparsely punctate and not 

 clothed with long, erect hairs; first two abdominal segments not 

 depressed or clothed with long pubescence at middle ; tibiae unarmed 

 at apex, and the posterior tarsi usually shorter than tibiae. 



Redescribed from a male and female in the United States National 

 Museum collection, which were reared from hickory twigs collected 

 at Kanawha Station, West Virginia, by Dr. A. D. Hopkins. Since 

 the type of this species has been lost, I am designating the male 

 from which the above description was made as the neotype.
