NORTH AMERICAN COLEOPTKRA. 271 



56. Ij. a'lnula n. sp. — Ol>loiig oval, slightly broader behind, facies rather 

 robust, brown, surftice distinctly pruinose, clothed with fine, short, recumbent 

 pubescence, ("lypeus emarjjinate, the border narrowly redesed, coarsely and 

 closely punctured, front more densely punctured with short semi-erect hairs. 

 Thorax very obtusely angulate, the margin subcrenate, surface equally punctured, 

 the punctures coarse and dense, not rugose nor confluent, each puncture bearing 

 a short hair, a few erect hairs along the apical margin, the sides ciliate with 

 longer hair. Elytra with punctures much finer than on the thorax less im- 

 pressed and much le.ss closely placed, each bearing a short recumbent hair; su- 

 tural costa distinct, discal costfe scarcely evident, submarginal costa distinct in 

 its entire length, hut not prominent; lateral margin ciliate with shorter hail's 

 than on the thorax. Pygidiura as closely punctured as the thorax. Metaster- 

 num not densely punctured. Abdomen rather finely and sparsely punctured, 

 with .short hairs. Legs more shining, usually reddish-brown. Claws with a 

 large acute tooth at middle, slightly smaller and near the base in the female. 

 Last joint of maxillary palpi long, slightly fusiform. Length .82 — .90 inch ; 

 21 - 23 mm. 



Male. — Antemial club scarcely as long as the funiculus. Ab- 

 domen vaguely impressed at middle, the jienultimate segment with a 

 slight triangular impression with feeble granulations each side. 



Female. — Antennal club very short. Posterior legs much stouter 

 than in S , the tibiae more dilated at tip. 



Variations. — The only variation observed is in cok)r. The typi- 

 cal form has the color and aspect of fully mature llich. One speci- 

 men before me is a very dark brown, almost piceou.s, from it the 

 pubescence has been in great part removed. 



This species resembles iUci><, and at superficial examination would 

 l)e taken for that, but there is no smooth median thoracic line so 

 coujuionly seen in that species. The structural (group) characters 

 will easily distinguish the two species. 



It has also considerable I'esemblance to parvidem, but in that spe- 

 cies the hair is somewhat coarser and in part erect. 



The hair covering the surface is very fine, and in carelessly col- 

 lected specimens may be abraded, but there will hardly be any diffi- 

 culty in assigning the species a place in the table. 



This is the only instance known to me in which the claws are 

 toothed nearer the base in the female than in the male. 



Occurs in northern Georgia (Morrison). 



57. Li. arcta n. sp. — t)blong, subcylindrical, brownish ferruginous, head pice- 

 ous, thorax a little darker than the elytra, semiojiaciue, surface clothed with ex 

 treniely fine, short pubescence. Clyi)eus feebly emarginate, margin narrowly 

 reflexed, surface densely i>unctured, front more finely and more densely punc- 

 tured. Thorax with sides arcuate, the margin entire, surface willi very fine and
