faintly widely emarginato, or subtruncate, slightly reflexed, lateral 

 angles moderately strongly rounded. Antenna 10-segmented, club 

 darker in color than funicle and varying from slightly longer to nearly 

 one-quarter longer than the funicle. Thorax with most of the disk 

 very finely, rather sparsely punctured, the punctui'es much larger 

 just behind the front margin and along the basal margin; center of 

 disk with small impunctate longitudinal area; along central basal 

 discal area and along all the margins, also frequently near the side 

 discal areas, with long, fine, and erect testaceous hairs, these some- 

 times rather thinned out through wear; lateral margins finely and 

 completely crenulate, front and hind angles strongly obtuse but 

 subangulate; basal margin entire though weak at center base. Elytra 

 very finely densely punctured, subrugosely wrinkled, with short erect 

 hairs near basal and scutellar area; sutural striae strong, the two others 

 moderately well indicated and strongly oblique. Pygidium somewhat 

 convex, very finely, moderately densely punctate, with very small 

 subprocumbent hairs (often nearly all abraded) , discal area frequently 

 very finely transversely wrinkled; apex truncate, ciliate, margin 

 thickened. Abdomen polished at middle, pruinose at sides, with 

 sparse punctures bearing short erect hairs: abdomen in lateral view 

 exactly as in L. falsa (see fig. 2, c) ; fifth with single row of fine erect 

 hairs near apex, apex somewhat narrowly incised at middle and the 

 segment with a longitudinal sulcus along the entire center area; 

 sixth as long as or longer than fifth, flat polished, slightly and spareely 

 punctm'ed with a few short suberect hairs, and with a faint longitu- 

 dinal median sulcus. Claws usually without any trace of a tooth, and 

 the basal margin very fine, scarcely noticeably serrate, at times, 

 however (not at all uncommonly), with a noticeable, short, triangular 

 tooth above middle, and almost subbasal in position. Front tarsi 

 with first segment rather strongly prolonged into a tooth at inner 

 apex, the second much less noticeably so. Front tibiae strongly 

 tridentate. First segment of hind tarsi subequal to second in length 

 but somewhat wider at apex. Hind tibiae with many to few long 

 thin hairs on inner side, often rather noticeably pilose. 



Female. — Antennal club slightly longer than segments 3-7 com- 

 bined. Pygidium a little less convex and sides more convergent 

 apically than in the opposite sex. Abdomen evenly convex, highly 

 polished, and finely and sparsely punctate at middle; fifth and sixth 

 segments in apical halves and at sides coarsely punctate. First 

 segment of the front tarsus with a small triangular tooth at the inner 

 apex. All claws with a small triangular tooth at the middle, the 

 surface between the tooth and the claw base minutely crenulate. 

 Otherwise similar to the male. 



Length. — 11.5-14.5 mm. Width. — 5-6.5 mm.
