carina extending from apex to about the middle, obtusely 
rounded at tip ; vertical portions without conspicuous pubescent 
areas; pygidium finely punctate, subacute at apex, the carina 
well marked but not projecting. Hind tarsi two-thirds as long 
as the tibiae, first joint just about equal in length to the four 
following joints united; anterior and middle tibiae with a dis- 
tinct mucro at the inner apex, posterior tibiae simple; claws 
similar on all the tarsi, divaricate, broadly toothed, the lower 
portion not incurved. 
Length, 7.25 millimeters; width, 1.8. 
Female . — Differs from the male as follows: Head darker in 
color; prosternum densely and roughly scabrous over entire 
surface, without distinct pubescence; first ventral segment con- 
vex, uniformly punctate and pubescent; last ventral convex, 
without longitudinal carina, obtusely rounded at apex; tibiae 
not mucronate.

Agrilus banahaoensis sp. nov. 
Male . — Form elongate, subcylindrical, front of head aeneous, 
occiput of head and pronotum cyaneous, elytra dark blue, be- 
coming violaceous posteriorly. 
Antennae aeneous, reaching a little beyond the middle of pro- 
notum, serrate from the fourth joint. Head with the front flat, 
the sides nearly parallel; occiput rather deeply and broadly 
impressed, with a feeble broad impression on the front ; surface 
strongly, transversely strigose, the intervals sparsely punctate, 
finely granulate and very sparsely clothed with a few incon- 
spicuous hairs. Clypeus wider than long, with the front 
margin truncate. Pronotum one-third wider than long, slightly 
narrower at base than apex; sides slightly sinuate, lateral mar- 
gin strongly sinuous when viewed laterally; hind angles rectan- 
gular, with a sharply defined, arcuate carina, the carina ending 
abruptly near lateral margin at basal third, disk moderately 
convex, a moderately deep, oblique, lateral depression and a vague 
anterior and posterior depression on the median line; surface 
finely, densely, and irregularly strigose, the intervals between 
the strigse densely and coarsely punctate, each puncture with 
a short, erect, inconspicuous hair. Scutellum transversely car- 
inate. Elytra with a slight posthumeral sinuation, behind
