segments, rather densely clothed with short, recumbent, white 
pubescence; first ventral segment convex, the middle with a 
longitudinal series of long, semierect, silken hairs ; last ventral 
feebly concave, with a series of longer hairs and distinct asperi- 
ties posteriorly, feebly, arcuately emarginate at apex; vertical 
portions except the first and second densely clothed with white 
pubescence; pygidium punctate, with a median carina, which is 
not projecting at apex. Hind tarsi not quite one-half as long 
as the tibise, first joint about as long as the second and third 
joints united; anterior tibiae feebly arcuate, wjth a very feeble 
mucro at tip ; middle and posterior tibiae simple ; claws similar on 
all tarsi, strongly cleft, the lower portion incurved, with the 
point not quite touching that of the opposite side. 
Length, 5.75 millimeters; width, 1.75. 
Female . — Differs from the male in having the front of head 
cupreous, slightly less pubescent; first ventral segment without 
distinct, long, semierect hairs, and by having all the tibiae simple. 
Described from six specimens, one male and five females. 
The type, which is a male, is from Davao, Mindanao ( Baker 
8325) ; alloptype from the same locality ( Baker 8365). Para- 
types : One female from same locality as type ; one female from 
Baguio, Benguet Province, Luzon ; one female from Puerto Prin- 
cesa, Palawan ; and a female from Mount Maquiling, Luzon, all 
collected by C. F. Baker. 
The female from Luzon has the front of head more convex 
and strongly, transversely rugose, becoming concentrically ru- 
gose on the vertex, and the front margin of prosternal lobe more 
squarely truncate than in the type. 
Agrilus rotundipennis sp. nov. 
Male . — Form elongate, subcylindrical, color uniformly dark 
blue, with a slight greenish tinge, each elytron with the tip and a 
round spot near suture at apical third of short white pubescence. 
Antennse brassy, reaching to middle of pronotum, serrate 
from the fourth joint. Head with the front nearly flat, sides 
slightly narrowed toward clypeus; vertex broadly and rather 
deeply impressed, the impression becoming nearly obliterated 
near clypeus ; surface sparsely and rather coarsely punctate, be- 
coming concentrically rugose on vertex, intervals smooth and 
shining, nearly glabrous. Clypeus slightly wider than long, with 
the front margin broadly, arcuately emarginate. Pronotum 
nearly one-half wider than long, not narrower at base than apex ; 
sides feebly arcuate in front, slightly sinuate behind the middle.
