hind the middle, then rather obliquely narrowed to posterior 
angles, which are obtuse; anterior margin broadly, arcuately 
emarginate; base bisinuate, with a rather abruptly rounded 
lobe at the middle; disk moderately convex, the convexity limited 
in front by a deep, transverse, angulate groove along the ante- 
rior margin, and behind by another, somewhat shallower groove 
along the posterior margin, limited on each side by a rather deep, 
broad depression; on each side an indistinct groove, perpendic- 
ular to the base; surface finely, densely granulate. Scutellum 
very small, triangular. Elytra a little wider than prothorax at 
base; humeral angles strongly angulate; sides slightly sinuate 
behind the humeri, strongly, obliquely narrowed from near the 
middle to the tips, which are separately rounded and very finely 
dentate; humeri not prominent, limited posteriorly by a de- 
pression along the lateral edge, causing the margin to become 
slightly flattened along the anterior third; suture slightly 
elevated near the apex; surface without coste, very finely 
granulate, with indistinct rows of very narrow, elongate punc- 
tures and indistinctly rugose. Beneath black, shining; abdomen 
marked with numerous oblong circles over entire surface; ante- 
rior margin of prosternum broadly, arcuately emarginate; tarsi 
and claws black, tarsal lamelle yellow. 
Length, 2.9 millimeters; width, 1. 
The type is from Mount Maquiling, Luzon (Baker); a para- 
type from Mount Banahao, Luzon (Baker). A specimen from 
Davao, Mindanao (Baker), is not quite typical of the species, 
the sides of the pronotum are more flattened and bronzy green, 
the transverse anterior groove on pronotum not quite as deep, 
and the disk with an obsolete transverse groove at the middle; 
otherwise it resembles the type and is best placed with this 
species for the present. 
This species is closely allied to A. bodongi Kerrem., but from 
the description given for that species, the anterior margin of 
the prosternum is truncate, while in piceipennis it is broadly, 
arcuately emarginate. In piceipennis the elytra are not de- 
pressed along the suture and the measurements of this species 
are less than those given for bodongi. 
Aphanisticus mindanaoensis sp. nov. 
Oblong-ovate, rather convex, uniformly shining black, with a 
slight bronzy reflection on sides of pronotum. 
Head very short, much narrower than prothorax; sides and 
front arcuately rounded, forming a half circle; front slightly,
