Antenne aéneous, becoming black toward tip, reaching to 
basal third of pronotum, serrate from the fourth joint. Head 
with the front convex, sides slightly narrowed toward clypeus, 
broadly and rather deeply impressed on vertex, less deeply on 
occiput; surface finely rugose, with the intervals sparsely 
punctate and very finely granulate, with a row of white hairs 
along lateral margin and a few sparsely placed ones behind 
clypeus. Clypeus slightly wider than long, with the front 
margin truncate. Pronotum one-third wider than long, slightly 
narrowed at base; sides nearly straight anteriorly, slightly ar- 
cuate behind middle and narrowly explanate; lateral margin 
strongly sinuate when viewed laterally; behind angles rectan- 
gular, with a well-defined arcuate carina, the carina extending 
to lateral margin near middle; disk convex, with a broad lateral 
depression and the median line with two vague depressions, 
the posterior the larger; surface finely, densely, irregularly 
strigose, the intervals between the ridges densely and coarsely 
punctate, each puncture with a short, erect, inconspicuous hair. 
Scutellum transversely carinate. Elytra distinctly sinuate 
behind the humeri, with a very feeble postmedian dilatation, 
then strongly narrowed to apices; sides of abdomen exposed 
above; each elytron emarginate at tip, the sutural angle 
produced into a long acute spine which is feebly serrate 
on the inner side, the lateral margin feebly serrate and ex- 
tending into a very minute spine; disk rather flat, without 
distinct costz, the sutural edge rather strongly elevated at 
apical third; humeri moderately prominent, not carinate; basal 
depressions moderately deep; surface shining, coarsely punctate- 
granulate, becoming smoother and feebly imbricate near apex, 
sparsely clothed with short, inconspicuous hairs and ornamented 
as above. Body beneath aéneous; prosternum densely and very 
finely punctate along the middle, clothed with fine, suberect, 
silky pubescence, sides coarsely punctate and scabrous; pro- 
sternal lobe broad, deeply and arcuately emarginate at middle; 
intercoxal process broad, sides feebly broadened behind coxe, 
apex truncate and biemarginate; propleura coarsely punctate 
and slightly strigose, sparsely pubescent; metasternum roughly 
scabrous, somewhat strigose and pubescent. Abdomen densely 
punctate at sides, especially near base, more sparsely along 
median line; first ventral segment slightly depressed at middle, _ 
Second with a narrow longitudinal smooth line extending to 
middle; last ventral broadly concave, with a feeble longitudinal
