elevated on the posterior fourth; surface without cost®, finely, 
densely granulate and obsoletely, transversely rugose, with indis- 
tinct rows of very narrow, long punctures. Beneath shining 
black; anterior margin of prosternum broadly, arcuately emar- 
ginate ; surface of abdomen marked with numerous, rather 
distinct, oblong circles; tarsi and claws black; tarsal lamellae 
yellow. 
Length, 3 millimeters; width, 1.1. 
Two specimens from Imugan, Nueva Vizcaya Province, Luzon 
( Baker 8334, 8337). 
Aphanisticus trachyformis sp. nov. 
Oblong-ovate, convex, uniformly bright bronzy black, shining. 
Head very short, much narrower than prothorax ; sides rather 
obliquely rounded ; front slightly, broadly excavated between the 
eyes, these not sharply margined on the inner side nor placed 
forward on a projecting front; surface shining, very finely, 
densely granulate, with a few large round punctures intermixed. 
Pronotum transverse, much wider than long; sides broadly ar- 
cuate, widest behind middle, then more strongly narrowed 
anteriorly; anterior margin broadly, arcuately emarginate, the 
angles rather obtuse; base bisinuate, with a large, widely 
rounded, median lobe in front of scutellum; disk evenly convex, 
sides slightly flattened; surface finely, densely granulate, with 
a few large punctures intermixed, the punctuation becoming 
denser along the lateral margin. Scutellum very small, trans- 
versely triangular. Elytra about as wide as prothorax at base ; 
humeral angles strongly angulate; sides slightly sinuate behind 
humeri, arcuately narrowed from the middle to the tips, which 
are separately, broadly rounded; humeri not prominent, just 
behind these a depression along the lateral edge, causing the 
lateral margin to become slightly flattened along the anterior 
third; suture elevated near apex; surface without costse, very 
finely granulate and indistinctly rugose, with a few large punc- 
tures intermixed, becoming obsolete toward apex. Beneath 
shining black; abdomen marked with numerous slightly oblong 
circles over entire surface ; anterior margin of prosternum 
slightly arcuate; tarsi and claws black; tarsal lamellae brown. 
Length, 3.25 millimeters; -width, 1.5. 
The type is from Tacloban, Leyte ( Baker 8335). Another 
specimen from Dapitan, Mindanao {Baker), differs from the 
type in being darker, without the bronzy reflections.
