is, 4 Fisher: New Coleoptera from the Philippines 437 
abruptly margined and placed at the extreme lateral part of the 
excavation; surface finely, densely granulate, with a few large 
punctures intermixed on the vertex. Pronotum transverse, 
much wider than long; sides very finely crenulate, broadly, 
evenly arcuate, widest at middle; anterior margin sinuate, with 
a large median lobe, the anterior angles rather acute ; base bisin- 
uate, with a large, acutely triangular lobe at middle; disk con- 
vex, the convexity formed by two abrupt, transverse elevations, 
separated by a very deep transverse groove, which extends 
around the ends of the posterior elevation, then extending along 
the base toward median lobe, the anterior elevation placed at 
middle of pronotum and abruptly truncate posteriorly, the 
posterior one not quite as long, with the top evenly rounded; 
along the anterior margin on the median lobe are two abruptly 
elevated teeth, pointing backward ; surface finely, densely granu- 
late, the granulation becoming somewhat finer on the elevations. 
Scutellum invisible. Elytra wider than prothorax at base; hu- 
meral angles obtusely angulate ; sides strongly sinuate behind the 
humeri and rather abruptly expanded just behind middle, then 
strongly, obliquely narrowed to tips, which are separately round- 
ed and finely dentate; median costa strongly elevated from base 
to apex, subsutural costa slightly nearer the median costa than 
the suture, strongly elevated, becoming suddenly obsolete at 
middle of elytron, an indistinct costa parallel to the lateral mar- 
gin, begining at the inflated portion, meeting the median costa at 
apex and extending around the tips of elytron and joining the 
suture, which is strongly elevated for its entire length; humeri 
strongly gibbous, with a distinct lateral costa, limited posteriorly 
by a very deep depression, reaching from median costa to inter- 
nal margin and posteriorly to the inflated lateral part of the ely- 
tron ; intervals very finely and densely granulate, with numerous 
transverse rugae between the costae on the anterior half of the 
elytron, the rugae as well marked as the costae. Beneath shining 
black, surface of abdomen marked with large oblong circles; 
anterior margin of prosternum truncate ; tarsi and claws black ; 
tarsal lamellae yellow. 
Length, 3.25 millimeters; width, 1.
