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 prosternum ; antennae 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 confluently 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. 
Leng*th, 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.
