middle. The penultimate ventral segment is faintly impressed transversely, and the 

 last joint is slightly emarginate at tip. 



Gkoup VI. 

 In this group we have a species of oblong form, glabrous upper surface, and 10-jointed 

 antennae ; the clypeus is slightly emarginate,- the mandibles are but little prominent, 

 the last joint of the maxillary palpi is distinctly oval, but has no lateral impression. 

 The thorax is not narrowed at the base, and is hardly serrate on the sides : the upper 

 spur of the posterior tibiae of the male is fixed, laterally inserted and is oblique, thus 

 causing the apical portion of the tibiae to be emarginate beneath : the upper spur is 

 flattened and acute : the claws are armed with a short acute tooth at the middle. 



14. L. eongrua, fusca, vel pallide castanea, oblonga, convexa, capite dense punctato, clypeo rnarginato, 

 late sub-emarginato, thorace brevi sat confertim punctato, linea saepe dorsali indistincto brevi, elytris 

 rugose punctatis subcostatis, subtus pallide brunnea, vel testacea, pectore dense villoso, antennis flavis.

New York, Georgia, and Texas. The pygidium is sparsely but strongly punctured. 

 Only males are known to me, and in them the club of the antennae is longer than the 

 stem, the last three segments of the abdomen are broadly and deeply channeled, the 

 penultimate has a deep posterior longitudinal line, and the last a triangular space 

 limited each side by a sharply defined edge ; the outline of the apex is sinuous, and 

 has, two small lobes at the middle. The inner posterior spur is straight, not shorter 

 than the outer, but oblique and connate, inserted upon the side, so as to produce a 

 deep inferior emargination. 



Geoup VII. 

 Contains a single oblong convex species, which, although glabrous above, is fringed 

 on the margin with long erect hairs. The head is moderate, the clypeus narrowly 

 margined, slightly emarginate ; the antennae are 10-jointed, the last joint of the 

 maxillary palpi slender, not impressed. The thorax is not narrowed behind ; the 

 breast is clothed with long dense hair ; the inner spur of the posterior tibiae of the 

 male is very long and irregularly bent, the outer one is equally long, but straight 

 and slender ; the tarsi are long, and the claws armed with a long tooth a little beyond 

 the middle, so as almost to appear cleft. 



15. L. futi 1 i s, oblonga convexa, pallide castanea nitida, capite dense punctato, sutura sublsevi, clypeo 

 anguste marginato. antice late emarginato, thorace sat dense punctato, lateribus serratis fimbriatis, 

 elytris rugose punctatis vix obsolete costatis, margine longe fimbriato, pectore dense longe villoso. 

 Long. -51 — 67. 



Lee. Agassiz' Lake Superior, 226. 



Lake Superior, New York, Kansas ; only males seen. Body oblong, convex ; head 

 densely punctured, with an indistinct smooth transverse line about the frontal suture ; 

 clypeus with narrow reflexed margin, slightly emarginate in front. Thorax one-half 

 wider than the head, short, tolerably densely, not very coarsely punctured, sides
