Abdomen rather finely strigose-punctate, more coarsely at the 
base, moderately pubescent; first ventral segment convex, not 
impressed nor more pubescent than rest of body; last ventral -

pubescent; pygidium rather strongly carinate, the carina pro- 
jecting and truncate at tip. Hind tarsi a little more than 
one-half as long as tibie; first joint fully as long as the four

Agrilus aguinaldoi sp. nov. 
Male.—Form elongate, parallel, head greenish blue, pronotum 
and base of elytra blue, with a strong violaceous tinge, balance 
of elytra purplish brown, becoming violaceous toward apex. 
Antenne piceous, with a metallic luster, reaching to middle of 
pronotum, serrate from the fourth joint. Head with the front 
strongly convex, the sides gradually narrowed from occiput to 
clypeus; widely and very deeply, longitudinally impressed from 
occiput to clypeus, with the impression suddenly expanded at 
the middle of the front; surface coarsely and rather densely 
punctured, becoming concentrically rugose on the occiput, in- 
tervals smooth, sparsely clothed with long white hairs on the 
anterior half, the hairs becoming finer and darker posteriorly. 
Clypeus nearly square, narrower at base, front margin truncate 
with an obtuse tooth at each anterior angle. Pronotum quad- 
rate, nearly as long as wide, slightly narrower at base than apex, 
sides rather strongly arcuate from apex to base; lateral margin 
very strongly sinuate when viewed laterally; hind angles rec- 
tangular, carina not well defined and reaching the lateral margin 
at basal third; disk strongly convex, with a very deep, round, 
lateral depression, the median line with a feeble impression in 
front of middle and a broad, deeper one in front of scutellum; 
surface coarsely, closely, and irregularly strigose, the intervals 
between the strige deep and densely, coarsely punctate, from 
each puncture arises a short, erect, inconspicuous hair. Scutel- 
lum strongly, transversely carinate, the carina bisinuate. 
Elytra strongly sinuate behind the humeri, with a strong post- 
median dilatation, entirely concealing the sides of the abdomen 
from above, from the postmedian dilation the sides are broadly,
