250 GEO. H. HORN, M. D. 



35. li. inai'j^inalis Lee. — Oblong, very little broader behind, rufocastane - 

 ous to brown, sliinin.i;. Clypeus moderately emarginate, the border very nar- 

 rowly reflexed, deeply and moderately coarsely punctured, front more coarsely 

 and deeply punctured. Thorax broadest at base, sides arcuately narrowed to the 

 front, margin slightly irregular but not crenate, with short cilise, surface shining, 

 the punctures very coaise. sparsely and irregularly placed, having large smooth 

 spaces on each side slightly in front of the middle, basal marginal groove feebly 

 distinct each side. Elytral punctures rather fine, moderately closely i)laced, the 

 costte distinct, but narrow and feebly elevated, the subniarginal costa well de- 

 veloped posteriorly in all specimens and in most of them extending to the hu- 

 meral iTJiiboue. Pygidium sparsely punctate, smoother at apex. Claws arcuate, 

 strongly toothed at middle. Last joint of maxillary palpus fusiform not im- 

 pressed. Metasternum densely punctured, the hair of moderate length, in the 

 female shorter and sparser. Length .65 — .85 inch; 16.5 — 21,5 mm. 



Male. — Antennal club a little longer than the stem. Abdomen 

 flattened at middle, the penultimate segment (fig. 28) with a semi- 

 circular I'ugulose elevation in front of a moderately deep, smooth 

 fovea. Last ventral segment vaguely longitudinally impressed. 

 Inner spur of hind tibia shorter than the outer and usually stout, 

 the outer spur long and slender. 



Female. — Antennal club shorter than the funiculus. Penulti- 

 mate ventral segment slightly impressed along the posterior border. 

 Hind tarsi a little shorter than the male. Pygidium slightly pro- 

 tuberant near the apex. 



Variations. — The punctuation of the thorax varies greatly. The 

 typical form has the punctures very sparsely placed, but so arranged 

 as to have a smooth transvei'se space on each side in front of the 

 middle, but specimens occur in which the ai"ea of the surface abso- 

 lutely smooth is greater than that with punctures. On the other 

 hand the punctures may be more abundant, so that the smooth space 

 is only vaguely indicated, as in ruffosa. Three specimens of the 

 larger size (.80 inchj have the sides of the thorax distinctly crenate, 

 but there is every degree from this to those in which the margin is 

 slightly irregular. A specimen 9 from Tennessee has the thorax 

 very coarsely and rather closely punctured, the punctures larger than 

 known to me in any other species. Without the male I am unwilling 

 to consider it distinct, and for the present place it as an extreme 

 variety. 



Occurs from New York to Wisconsin and Illinois (southward to 

 Tennessee?). 



36. li. spreta n. sp. — Oblong, elytra slightly wider at middle, castaneous or 

 fuscous, shining. Clypeus feebly emarginate, margin very narrowly reflexed. 

 densely and moderately coarsely punctured, front rather more coarsely but less
