median lobe in front of scutellum; disk rather suddenly convex, 
with the sides slightly flattened, the convexity with an indistinct 
groove posteriorly, and a broad, rather deep depression near 
each of the posterior angles; surface finely, densely granulate, 
with a few large punctures intermixed. Scutellum very small, 
transversely triangular. Elytra about as wide as prothorax 
at base; humeral angles strongly angulate; sides slightly sinuate 
behind the humeri, strongly, obliquely narrowed from near mid- 
dle to the tips, which are separately rounded and finely dentate ; 
humeri not prominent, just behind these a deep depression along 
the lateral edge, causing the margin to become slightly flattened 
along the anterior third; suture broadly elevated near apex; 
surface without cost, finely, densely granulate and obsoletely 
rugose, with a few large punctures forming indistinct rows on 
the disk. Beneath shining black, surface of abdomen without 
distinct circular marks; anterior margin of prosternum broadly, 
arcuately emarginate; tarsi and claws black; tarsal lamelle 
brownish. 
Length, 2.75 millimeters; width, 1.25. 
One specimen from Puerto Princesa, Palawan (Baker). 
Aphanisticus unicolor sp. nov. 
Elongate, rather convex, uniformly. shining black. 
Head very short, much narrower than prothorax; sides and 
front arcuately rounded, forming a half circle; front not dis- 
tinctly excavated between the eyes, these not sharply margined 
on the inner side nor placed forward on a projecting front as in 
costipennis; surface very finely, densely granulate, with a few 
large, round, indistinct punctures intermixed. Pronotum trans- 
‘verse, much wider than long; sides broadly, evenly arcuate, 
widest at middle; anterior margin broadly, arcuately emarginate, 
the anterior angles acute; base bisinuate, with a large, rounded, 
median lobe in front of scutellum; disk moderately, evenly con- 
vex, with the sides slightly flattened; surface finely, densely 
granulate, with a few large punctures intermixed. Scutellum 
very small, triangular. Elytra a little wider than prothorax 
at base; humeral angles sharply angulate; sides strongly sinuate 
- near middle, then obliquely narrowed to the tips, which are 
separately rounded and finely dentate; humeri not prominent, 
just behind these a deep depression, causing the lateral margin to . 
become slightly flattened along the anterior third; suture broadly
