A^ARIATIONS. — While in the greater number of specimens the 

 thoracic punctures are equally scattered, many occur with smooth 

 impunctured spaces, usually one on each side in front of the middle. 

 The hairs on the front are often lost by abrasion, in such specimens 

 the specific name may cause doubt. 



With this species I unite hirticeps Lee, described like villifwm from 

 a single specimen. The measurement given for the former .92 inch 

 is evidently a typographical error for .62 inch. 



Occurs in Canada, Pennsylvania, Illinois and Iowa. For hirticeps 

 LeConte says Georgia, but this is doubtful. 



50. Li. liiiiiila n. sp. — Oblong, scarcely broader behind, convex, robust, rufo- 

 testaceous, shining. Clypens eraarginate, the border narrowly reflexed, surface 

 rather coarsely densely punctured, front convex, more coarsely punctured, a 

 slight impression at middle of front. Thorax short, broad, rather more defiexed 

 than usual, sides arcuately narrowed from base to apex, margin somewhat irreg- 

 ular, but not crenate, sparsely ciliate, a distinct basal channel, disc moderately 

 coarsely punctate, the punctures not close, but somewhat irregularly scattered. 

 Elytra more finely and closely punctured than the thorax, the surface smoother 

 near the apex, sutural costa narrow, feebly elevated, the first discal moderately 

 distinct, the others scarcely evident, the submarginal faintly distinct near the 

 apex. Pygidium sparsely punctate, smoother near the apex. Metasternum 

 densely punctured, the hair long and dense % , shorter and less dense 9 • Ab- 

 domen at sides sparsely punctate, the last two segments more coarsely. Claws 

 ai'cuate, a strong median tooth in both sexes. Last joint of maxillary palpi 

 slightly fusiform, not impressed. Length .55 — .72 inch ; 14 — 18 mm. 



Male. — Antennal club veiy little longer than the funiculus. Ab- 

 domen flattened at middle, the penultimate segment with an obtuse, 

 transverse ridge divided by a depression at middle. Last ventral 

 concave, the anterior margin elevated. Inner spur of hind tibia 

 broad and stout, obliquely truncate at apex. 



Female. — Antennal club shorter than the funiculus. Spurs of 

 hind tibise more slender. Pygidium more elongate and smoother. 

 Posterior tarsi shorter than in the male. 



Variations. — While the greater number of specimens have the 

 costse as described, others have them more evident. The color varies 

 but little. The thoracic punctuation varies in distinctness, but not 

 greatly. 



This species greatly resembles cephalica, and like that species is 

 more convex in outline when viewed laterally. 



Occurs southward of Hudson's Bay, Montana, Colorado, Utah and 

 Illinois.
