behind the clypeus with short, erect, white hairs. Clypeus 
a little wider than long, with the front margin slightly, 
arcuately emarginate. Pronotum a little more than one-half 
wider than long, base and apex nearly equal in width, sides 
slightly arcuate; lateral margin feebly sinuate; hind angles 
rectangular, with a well-defined, sinuate carina, the carina 
close to lateral margin and joining it near the apical angles; 
disk convex, a moderately deep impression behind the front 
angles, and on the median line two depressions, the ante- 
seutellar one much deeper and larger than the anterior one, 
which is nearly obsolete; surface rather finely and irregularly 
strigose, the intervals between the ridges rather densely and 
finely punctate. Scutellum rather wide, sharply, transversely 
bicarinate. Elytra slightly sinuate behind the humeri, with 
a feeble postmedian dilatation, then obliquely narrowed to the 
apices, which are conjointly, obtusely rounded without serrula- 
tion, sides of abdomen narrowly visible from above; disk 
feebly flattened, slightly concave posteriorly along suture, with- 
out distinct costs, sutural edge elevated behind the middle, with 
a sharply elevated carina extending from humeri to the basal 
third and on a line with the prothoracic carina; basal depressions 
deep; surface subopaque, finely and densely, imbricately granu- 
late, rather densely clothed with distinct, short, whitish, recuni- 
bent pubescence. Body beneath aéneous, more shining than 
above; prosternum finely, densely scabrous, and very vaguely pu- 
bescent; prosternal lobe broadly rounded in front; intercoxal 
process gradually, obliquely expanded to behind coxe, then 
abruptly narrowed to the apex, which is rather obtuse; propleura 
coarsely and densely, reticulately punctate; metasternum rather 
strongly, densely punctate-strigose and feebly pubescent. Abdo- 
men more sparsely punctate-strigose than metasternum, the 
strige becoming finer posteriorly; first ventral segment convex; 
not impressed or more pubescent than rest of surface; last seg- 
ment very obtusely rounded at apex; vertical portions of segments 
evenly and very vaguely pubescent; pygidium without projecting 
carina. Hind tarsi about one-half as long as the tibiee, the 
first joint about equal in length to the four following joints 
united ; tibize simple; claws on all the feet cleft at middle forming 
a rather long, acute tooth. 
Length, 4.3 millimeters; width, 1.25. 
Described from a unique female from Mount Maquiling, Luzon 
(Baker).
