and slightly emarginate in front of the scutellum. Scutellum 
rather large, triangular. Elytra a little wider than pronotum 
at base, slightly sinuate near posterior coxe, then strongly 
attenuate to the tips, which are conjointly, broadly rounded; 
humeri not prominent; surface with a distinct straight lateral 
carina, reaching from posterior part of humerus to near the 
apical margin, finely punctate and slightly rugose, with a shallow 
broad depression along base and a deeper one along lateral 
margin behind the humerus, very sparsely clothed with short, 
yellow, recumbent hairs, becoming a little denser along lateral 
margin, and forming three inconspicuous, transverse bands 
which are interrupted at the suture; the first at about the middle, 
the second at apical third, and the last one at the apex. Beneath 
convex; abdomen densely marked with semicircular lines, in the 
middle of which is a small puncture; intervals very finely 
granulate, with a few extremely short white hairs; prosternum 
distinctly divided into two parts, the anterior part bent down- 
ward, with the front margin truncate and slightly elevated; in- 
tercoxal process transverse, flat, distinctly narrower in front 
than behind, apex truncate, the angles rounded; mesosternum 
with the anterior margin truncate; tarsi and claws black. 
Length, 3.25 millimeters; width, 2. 
One specimen from Zamboanga, Mindanao (Baker).

Elongate, convex, enlarged anteriorly; above of a bright

Head with the front rather deeply concave between the eyes, 
median longitudinal groove not distinctly marked; surface 
nearly smooth, punctuation indistinct except under a high-power 
lens, with a deep puncture near base of antennz and a widely 
angulated median depression in front of clypeal suture, sparsely 
clothed with short, light yellow, recumbent hairs; eyes rather 
strongly margined on the inner side; epistoma wide, elevated, 
finely, transversely strigose, anterior margin truncate, the an- 
gles acute and extending beneath base of antenne, which are 
rather widely separated; clypeal suture distinct, subtruncate. 
Pronotum short, a little more than three times as wide as long, 
narrower in front than behind; stirface rather densely mark 
with inconspicuous circles, becoming smoother on the disk, 
sparsely clothed with short, light yellow, recumbent pubescence ; 
anterior margin deeply, arcuately emarginate, the angles acute;
