emarginate at apex, with a few sparsely placed asperities along 
the apical margin; vertical portions of the segments evenly 
pubescent; pygidium without projecting carina. Hind tarsi about 
one-half as long as the tibise, first joint fully as long as the four 
following joints united; anterior tibiae feebly arcuate, the middle 
and posterior ones straight; claws divaricate, cleft at middle, 
forming an acute tooth, the lower portion not incurved.

Agrilus tayabensis sp. nov. 
Male . — Form elongate, slender; color olivaceous bronze, with 
the head dark green. 
Antennae brassy, with the outer six or seven joints cupreous, 
densely and finely granulate, reaching to basal third of pro- 
notum, serrate from the fourth joint. Head with the front 
slightly convex, the sides nearly parallel to vertex, then slightly 
narrowed posteriorly; vertex slightly, longitudinally impressed; 
surface coarsely and very densely punctate, more rugose on 
the occiput and densely clothed in front of clypeus with long 
white pubescence. Clypeus slightly wider than long, with the 
front margin truncate. Pronotum nearly one-half wider than 
long, strongly narrowed toward the base, slightly arcuate in 
front, sinuate behind the middle; lateral sides nearly straight 
when viewed laterally; hind angles rectangular, with a sharply 
defined, strongly arcuate carina, the carina reaching lateral 
margin at the middle; disk moderately convex, with a broad, 
vague, lateral concavity and a faint antescutellar depression; 
surface rather finely, closely, transversely strigose, the intervals 
finely punctate. Scutellum strongly, transversely carinate. Ely- 
tra feebly sinuate behind the humeri, with scarcely any post- 
median dilatation, then obliquely narrowed to the apices, which 
are separately, obtusely rounded and rather finely serrulate, 
sides of abdomen broadly exposed above; disk flattened, with- 
out distinct costae, sutural edge feebly elevated near apex, hu- 
meri moderate, not carinate; basal depressions rather deep; 
surface shining, finely and densely, imbricately granulate, 
sparsely clothed with short, yellow, recumbent hairs, forming a 
broad inconspicuous vitta along the suture. Body beneath 
olivaceous bronze; prosternum sparsely granulate anteriorly, 
between the coxae rugose, nearly glabrous ; prosternal lobe broad- 
ly rounded, with a small acute emargination at middle; inter-
