Head with the front broadly concave between the eyes, with- 
out distinct median groove; surface with a deep puncture near 
base of antennse and indistinctly marked with small circles, 
glabrous; eyes rather strongly margined on the inner side; 
epistoma wide, flat, anterior margin very deeply, arcuately 
emarginate, anterior angles rather broad ; antennse widely 
separated; clypeal suture not distinct. Pronotum strongly con- 
vex, short, two and one-half times as wide as long, slightly 
narrower in front than behind; surface nearly smooth, rather 
densely marked with nearly obsolete circles, similar to those of 
the head; anterior margin arcuately emarginate, the angles 
rather obtuse; sides slightly flattened, arcuate to the middle, 
then obliquely widened to the posterior angles, which are nearly 
rectangular; base bisinuate, with a broadly rounded median 
lobe in front of the scutellum. Scutellum very small, triangular. 
Elytra strongly convex, without any conspicuous depressions, 
slightly wider than pronotum at base, parallel to near middle, 
then strongly, arcuately attenuate to the tips, which are con- 
jointly, narrowly rounded; humeri not prominent; surface 
without lateral carina, densely, irregularly, and coarsely 
punctate. Beneath convex; abdomen rather densely marked 
with semicircular lines and very finely granulate, glabrous; 
prosternum divided into parts, anterior margin truncate, 
sharply margined; intercoxal process elevated, elongate, wider 
behind than in front, sides slightly margined, apex rounded; 
mesosternum with the anterior margin deeply, arcuately 
emarginate; tarsi and claws black. 
Length, 2.9 millimeters; width, 1.7.

Head with the front slightly concave between the eyes, with 
a distinct, median, longitudinal groove reaching from apex to 
middle; surface smooth, with a small round puncture near base 
of antennse, rather densely marked with indistinct circles, and 
sparsely clothed with reddish yellow, recumbent pubescence; 
eyes slightly margined on the inner side ; epistoma wide, smooth, 
and not elevated, anterior margin rather deeply, arcuately 
emarginate, angles rather broad; antennse widely separated; 
clypeal suture not visible. Pronotum short, three times as
