densely granulate, with a few large punctures intermixed on the 
vertex. Pronotum broadly cordate, much wider than long; 
sides very finely crenulate, broadly, arcuately rounded poste- 
riorly to the middle, then obliquely narrowing to posterior angles, 
which are obtuse; anterior margin broadly, arcuately emargin- 
ate; base bisinuate, with a rounded median lobe, somewhat 
elevated, in front of the scutellum; disk convex, the convexity 
formed by two abrupt transverse elevations, the anterior one 
consisting of two semicircular swellings joined together at the 
middle, with the tips pointing backward, the posterior elevation 
consisting of a broadly triangular swelling, joined anteriorly to 
the front elevation on the median line and posteriorly to the 
median lobe in front of scutellum; surface finely, densely gran- 
ulate, the granulation becoming somewhat finer on the elevations. 
Elytra distinctly wider than prothorax at base ; humeral angles 
obtusely angulate; sides strongly sinuate behind the humeri to 
near the middle, then obliquely narrowed to the tips, which are 
separately, broadly rounded and very finely dentate; on the mid- 
dle of each elytron a distinct sinuate median costa reaching from 
base to near apex, then following the outline of elytral tip and 
joining the suture, which is strongly elevated on the posterior 
half, an indistinct subsutural costa, subequally distant between 
the median costa and suture, becoming obsolete just behind the 
middle, and another indistinct costa parallel to the anterior mar- 
gin, beginning just back of the lateral depression and joining the 
median costa near the apex; humeri with a distinct oblique 
costa, limited posteriorly by a rather deep depression reaching 
from the median costa to the anterior margin ; intervals 
strongly, densely granulate, with a few indistinct, irregular, 
transverse rugae between the costae. Beneath shining black, 
surface of abdomen marked with large oblong circles; anterior 
margin of prosternum sinuate; tarsi and claws black; tarsal 
lamellae yellow. 
Length, 4 millimeters; width, 1.25.

Elongate, subconvex, uniformly shining black. 
Head elongate, slightly wider posteriorly, distinctly narrower 
than the prothorax; front rather widely and deeply excavated 
between the eyes, lateral sides of excavation more obliquely con- 
cave than in costipennis, subparallel; eyes with the inner side
