yellow, long and dense. Claws arcuate, a strong acute median tooth. Length, 

 ,68 inch = 17 mm. 



Habitat — South Carolina (Morrison), Grand Ledge, Mich., May 

 24th, (Schwarz). 



Malk. — Antennal ckib a Httle longer than the stem. Abdomen 

 slightly flattened at middle, the penultimate segment with a transverse, 

 arcuate, rugulose elevation, behind which is a concavity. Last ventral 

 flat. Inner spur of hind tibia fully as long and scarcely stronger than 

 the outer. 



Female. — Wanting. 



Three specimens of this form, which is perhaps confused with hir- 

 suta (with which it agrees in group characters) in collections, are before 

 me, all of them males. It is readily known by the almost equally long 

 spurs of the male, and by the distinct lines of longer hair on the elytra. 

 The thoracic margin is also evidently, if not strongly, crenulate, 



L. innominata, sp. nov. 



Oblong oval, convex, chestnut brown, shining. Clypeus moderately deeply, 

 acutely emarginate, the border moderately reflexed, surface rather closely and 

 coarsely punctate, front less densely and more coarsely punctate. Thorax, sides 

 arcuate, narrowing rather regularly toward apex, the margin scarcely irregular, not 

 crenate, with long cilise, the punctures small, sparse and irregularly placed, no 

 median line, a distinct channel along the base externally. Punctures of the elytra 

 more coarse and dense than those of thorax, the costse evident, but not prominent. 

 Pygidium sparsely ;ndistinctly punctate. Metasternum punctate, the hair (-/') long 

 and abundant. Abdomen indistinctly punctate at th3 sides, the la-t two rt-gments 

 more coarsely punctate. Claws arcuate, a long acute median tooth, smaller on 

 anterior tarsi. Last joint of maxillary palpi fusiiorm. Length, .72 inch = 1^5 mm. 



Habitat— V\^\v\on2L, Minn., U. S. N. Mus. Ace. 21542. 



Male. — Antennal club as long as the stem. Abdomen flattened 

 and slightly concave at middle. Penultimate segment with a rather 

 feeble, semicircular depression on each side of which is a short oblique 

 tuberosity. Last segment transversely concave, almost cupuliform. 

 Inner spur of hind tibia rather more than half the length of the outer, 

 stout and straight. 



Female. — Unknown. 



This species is known to me in a single male specimen only. It is 

 intermediate in some respects between ifnplicita and balia, yet abundantly 

 distinct from either. The male characters are more like those of implicita 

 save that the last segment is concave, but the very smooth, sparsely 

 punctured thorax is distinctive. This species is also much larger than 

 its immediate allies.
