coarse, sparse, shallow punctures; elytra coarsely undulate- 

 punctate. Ventral surface and legs smooth. 



Head in dorsal view subglobose, front obtusely excavate (an- 

 gle of 134°) (Plate II, figs. 2 and 12), frontal sulcus deep; 

 eyes obtuse-ovate, occupying one-half the total width and three- 

 fourths the length of head, in profile front strongly retreating 

 so that trophi nearly touch presternum ; antennse with segments 

 5 to 11 progressively acutely serrate, finely setose, segments 1 

 and 2 ovate, glabrous, 3 slender, 1 with few setae, 2 and 3 bare ; 

 antennal groove somewhat sinuous (Plate II, fig. 6). 



Pronotum two and one-half times as wide as long, cephalic 

 margin feebly sinuous, except laterad where it projects ce- 

 phalad with an acutely rounded angle, lateral margins obliquely 

 arched and somewhat convergent caudad to form a slightly ob- 

 tuse angle with caudal margin; caudal margin nearly straight, 

 but with a curved submedial emargination to fit elytra; disk 

 with two large, shallow, transverse, submedian sulci, separated 

 by an area one-half their width, caudolateral area shallowly 

 excavate, cephalolateral area less so and separated from former 

 by an oblique elevation which is continued mediad to form cau- 

 dal border of the transverse sulci described above; scutellum 

 small, subequilaterally triangular, depressed mediad (Plate II, 

 fig. 2). 



Elytra very slightly wider than pronotum with sides parallel 

 for a little more than five-eighths of their length, then evenly, 

 roundly converging to their apices which are subsemicircular 

 and with a few almost obsolete denticulations, humeral area 

 with a prominent knob, apical area with a narrow, shallow 

 obsolescent subsutural sulcus, each elytron with an obsolescent 

 transverse depression at its first and second thirds; entire ely- 

 tral area transversely confidently undulate, rugose or punctate- 

 rugose. 



Legs bronze-brown, brilliant, glabrous, basal halves of pos- 

 terior femora fit into well-defined transverse pits in the sub- 

 lateral portions of the metasternum; femora lenticulately flat- 

 tened, with shallow, wide sulcus on apical area, between which 

 and the body the tibia and the tarsus are hidden when at rest ; 

 tarsi with golden to pale yellow ventral pilosity. 



Length, 3.65 millimeters; width at elytra, 1.50; length of 

 head, 0.45; length of pronotum, 0.55; length of elytra, 2.65; 

 length of scutellum, 0.25.
