NORTH AMERICAN COLEOPTERA. 268 



gidium coarsely sparsely punctured, smoother near the apex. Metasternuni 

 densely ])unctate. the hair moderately lonjf and dense; sides of abdomen sjjarsely 

 punctate, the last two seginents more coarsely. Claws curved, the tooth strong 

 and median. Last joint of maxillary palpi slightly fusiform, not impressed- 

 Length .60 — .64 inch ; 15 — 16 mm. 



Male. — Club of antenna as long as the stem. Abdomen bi-oadly 

 flattened at middle, the penultimate segment with an arcuate, trans- 

 verse elevation in front of a slight concavity. Last segment with a 

 cupuliform depression, the anterior margin somewhat elevated. Inner 

 spur of hind tibia two-thirds as long as the outer and not thicker. 



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

 nuni less hairy than in the male, the hind tarsi distinctly shorter. 



Variations. — As in all species with the thoracic punctures rather 

 sparse, their distribution is somewhat irregular, although not so ob- 

 viously as in viliij'rons. 



This species is more decidedly oval in outline than either viUlfrom 

 or hirsuta. It is the only species of the present group in which the 

 last ventral S has a well defined concavity, the ridge on the penul- 

 timate segment is very like hirsuta. 



Occurs in the Middle States region westward to Illinois, a specimen 

 given me marked Arizona is looked upon with doubt as to locality, 



49. L.. villirroiiiti Lee. — Oblong, moderately elongate, slightly broader he- 

 hind, rufotestaceous or castaneous, shining. Head coarsely and closely, almost 

 crihrately punctured. Clypeus deeply emarginate, the border narrowly retlexed, 

 frontal suture deeply impressed, front with short erect hairs. Thorax narrowed 

 in front, the sides regularly arcuate, the margin not crenate, with short ciliie, a 

 distinct sulcus along the basal margin externally, disc shining, the punctures 

 coarse and deep, sparsely placed, in many specimens there are large smooth 

 spaces. Elytral punctures coarse and very closely placed, the discal costse very 

 indistinct. Pygidium with coarse, sparsely placed, indistinct ininctures. Meta- 

 sternuni densely punctured, the hair moderately long, but not dense. Abdomen 

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

 curved, a strong acute tooth at middle. Last joint of maxillary palpus cylin- 

 drical, not impressed. Length .56 — .62 inch ; 14.5 — 16 mm. 



Male. — Antennal club (fig. 5) as long as the stem. Abdomen 

 broadly flattened at middle, penultimate segment with a feeble ar- 

 cuate elevation. Last segment broadly concave with a longitudinal 

 impression at middle. Inner spur of hind tibia two-thirds the length 

 of the outer, acute, moderately stout. Pygidium broad, the i)unc- 

 tures large, but shallow. 



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

 nuni with shorter hair. Pygidium more oval and shining, the punc- 

 tures smaller, but sharply impressed.
