Male. — Robust-oval, testaceorufous, head and thorax rufous, shining 

 and densely hairy above. Head and clypeus coarsely, variolately, not 

 rugosely punctate, the punctures of front and vertex separated by 

 one-half to once their diameters, with erect hair; the punctures of 

 clypeus a little smaller and sparser than those of the front; carina of 

 vertex moderately sharp and distinct; clypeus sharply reflexed, apex 

 subtruncate, angles rounded. Antenna 9-segmented, third and fourth 

 segments longer than broad and subequal, fifth and sixth transverse 

 or subtransverse and shorter than the third and fourth; club small and 

 somewhat lighter colored than funicle and subequal to, or slightly 

 longer than, the funicle. Thorax with lateral margins roundly dilated, 

 with long cilia, hardly noticeably crenulate ; hind angles vaiying from 

 with no trace of any angle to slightly through very obtusely angulate, 

 the basal margin fine but entire ; front angles obtuse and not prominent ; 

 disk finely punctured, the punctures separated by a distance equal to 

 once to twice their diameters, with fine long erect hair over the major 

 portion of the disk. Elytra moderately rugosely wrinkled, finely 

 sparsely punctate, with veiy fine, long, erect hairs, these hairs shorter 

 near apex; apex of each elytron as viewed from above apparently 

 truncate or subtruncate; pygidium convex, highly polished, very finely, 

 scarcely perceptibly punctate, w^th sparse, suberect, short hairs in 

 basal area, apex rounded to subtruncate and often somewhat explan- 

 ate. Abdomen polished at center, smooth, with dense short hair on 

 sides, sutures obsolete; fifth segment wrinkled on sides, apical margin 

 somewhat raised and slightly, semicircularly emarginate at apex; 

 sixth segment longer than fifth, with a raised, transverse, cariniform 

 process m the shape of a very wide V just apical from the basal margin; 

 the summit of the carinae with a few short hairs, the remainder of the 

 surface flattened and impunctate except for the ciliate apical margin. 

 All claws finely pectinate along a double margin, the outer margin of 

 each claw with a large tooth just slightly beyond middle, at times the 

 hind claws subpectinate or serrate. 



Female. — Thorax slightly less densely punctate. Antenna ap- 

 parently 9-segmented, club ovate but nearly equal to funicle. Pygidi- 

 um somewhat convexly flattened, disk with fine, moderately dense 

 punctures, with a few very fine, short, and erect hairs; disk in apical 

 two-fifths moderately deeply and broadly longitudinally impressed, the 

 surface each side of the impression slightly gibbose; apex shghtly 

 emarginate, the sides of emargination broadly rounded. Abdomen 

 convex, highly polished and with fine, moderately dense setiferous 

 punctures, the hairs rather fine and short; segments 1-4 with sutures 

 nearly effaced at the middle; fifth segment transversely impressed in
