Psyche 
[March- June 
rugose ; prosternal process wide, depressed at middle, 
rounded at apex. Abdomen very finely punctate ; disk of the 
last segment arcuately emarginate at apex, the pleural mar- 
gin feebly emarginate at middle, separated from the disk of 
the segment by a deep, narrow, entire groove; the apex 
bordered by some long erect hairs. The suture between the 
first two segments not distinct. Tibiae slender, the anterior 
nearly straight ; tarsi elongate. 
Seventeen specimens of this new species (type, M. C. Z. no. 
22,516) were captured at Yandina, Russell Islands, by Dr. 
W. M. Mann; paratypes of this species are in my own col- 
lection and in that of the British Museum. 
Agrilus levuensis n. sp. (PI. IV, Fig. 12) 
Length: 11 mm.; breadth: 3 mm. — 9. Shining bluish 
black with a violaceous tinge above, of the same color below ; 
elongate, rather robust; elytra sinuate laterally from the 
shoulders to behind the middle, then sinuously narrowed to 
the tips, which are separated, each ending in a strong spine. 
Elytra with a wide sulcus along the suture, the surface finely 
and irregularly punctate and clothed with short, greyish, 
recumbent pubescence which is scarcely distinguishable. 
The front with a large white spot. Abdominal segments 
with, on each side, little depressions not reaching the margin, 
and clothed at bottom with recumbent white pubescence. 
Head rather wide, with the front strongly concave be- 
tween the eyes, the excavation carinate at the sides along 
the eyes, finely grooved at middle; the sides of the front, 
between the eyes, are at first parallel, then abruptly con- 
vergent toward the epistoma; the surface covered with 
transverse and slightly oblique wrinkles. Eyes elliptic, large, 
reaching the anterior margin. Antennae extending nearly 
to the middle of the pronotum, serrate from the fourth joint, 
the second joint wider than, and once and a half as long as, 
the third. 
Pronotum trapezoidal, scarcely once and three quarters as 
wide as long, widest at the base ; the anterior margin scarcely 
bisinuate ; the sides straight, a little angulose at middle ; the 
base deeply bisinuate, with the median lobe truncate in front 
of the scutellum. The posterior angles obtusely angulate; 
the marginal carina feebly sinuate; the lower carina obso-
