Agrilus davaoensis sp. nov. 
Male . — Form elongate, rather slender, olivaceous bronze vary- 
ing to cupro-aeneous. 
Antennae greenish black, nearly attaining the hind angles of 
pronotum, serrate from the fourth joint. Head with the front 
rather narrow and slightly convex, the sides parallel from oc- 
ciput to middle of front, then strongly narrowed to clypeus; 
occiput moderately impressed, the impression extending to mid- 
dle of the front ; surface coarsely, transversely rugose, intervals 
sparsely and coarsely punctate, nearly glabrous. Clypeus 
strongly elevated, slightly wider than long, with the front mar- 
gin broadly, arcuately emarginate. Pronotum one-half wider 
than long, slightly narrower at base than apex; sides rather 
strongly arcuate from apex to base ; lateral margin feebly sinuate 
when viewed laterally; hind angles rectangular, with a sharply 
defined sinuate carina, the carina joining the lateral margin a 
little in front of middle; disk convex, a feeble, oblique depres- 
sion extending from lateral margin to base along inner side of 
lateral carina, and on the median line two depressions, the ante- 
scutellar one the larger; surface rather coarsely, closely, trans- 
versely strigose, the intervals between the strigse sparsely and 
finely punctate. Scutellum sharply, transversely carinate. 
Elytra slightly sinuate behind the humeri, a little broadened be- 
hind the middle, then obliquely narrowed to apices, which are 
separately and rather acutely rounded, without serrulation, sides 
of abdomen exposed ; disk rather convex, without distinct costse, 
sutural margin elevated, from the middle, with a sharply 
elevated carina extending from the humeri to near the middle, 
on a line with the prothoracic carina; basal depressions deep; 
surface shining, densely, closely, imbricately granulate, and 
rather densely clothed with distinct short, whitish, semierect 
pubescence. Body beneath piceous, with a strong brassy 
metallic luster; prosternum coarsely, densely scarbrous and 
vaguely pubescent ; prosternal lobe wide, broadly subtruncate in 
front; intercoxal process broad, sides gradually widened behind 
the coxsg, then abruptly narrowed to apex, which is obtuse ; pro- 
pleura densely, coarsely punctate and moderately strigose ; 
metasternum densely, coarsely punctate-strigose and rather 
densely pubescent. Abdomen sparsely and rather finely 
punctate-strigose, the strigse becoming finer posteriorly, very 
sparsely clothed with short pubescence; first ventral segment 
convex, not impressed nor conspicuously pubescent ; last segment 
feebly emarginate at apex ; vertical portions of segments vaguely
