[March- June 
the bottom of this depression very finely punctate and clothed 
with an inconspicuous pale pubescence. The epistoma sepa- 
rated from the front by a swelling. Eyes elliptic, feebly con- 
vex, converging to the occiput ; antennae reaching the level of 
the anterior cotyloid cavities. 
Pronotum a little more than once and one third as wide at 
base as at the anterior margin, and a little more than once 
and a half as wide as long; widest at the base; the anterior 
margin strongly arcuately emarginate; the sides feebly at- 
tenuate from the base to the anterior third, then arcuately 
narrowed to the anterior angles, the posterior acute and 
rather prominent; the base nearly tranversely truncate. 
Disk coarsely sculptured, the punctures becoming more 
distinct near the sides and the anterior angles ; the middle 
of the surface narrowly furrowed; each side with a deep, 
wide depression, finely punctured, occupying half of the 
length and reaching the posterior margin. 
Scutellum small, rounded posteriorly and straight an- 
teriorly, smooth. 
Elytra as wide as the pronotum at base, slightly expanded 
and truncate at the shoulders, then nearly parallel to behind 
the middle, and straight and strongly acuminate to the tips, 
strongly and sharply serrate along the margin from the 
middle to apex; the sutural angle toothed. Surface with 
eight punctate striae, the juxtasutural stria reaching only 
from the base to the basal quarter of the length ; the intervals 
between the striae very slightly convex. 
The prothoracic episterna, and the sides beneath, very 
finely punctate and clothed with very inconspicuous re- 
cumbent pubescence; the middle of the body shining, gla- 
brous, very sparsely punctate. Prosternal process deeply 
furrowed and coarsely punctate at middle; first abdominal 
segment flattened at middle ; last abdominal segment brown- 
ish, constricted at apex, angularly and feebly emarginate. 
Legs and tarsi long. 
A single specimen (type, M. C. Z. no. 22,508) of this very 
beautiful species was captured by Dr. W. M. Mann at 
Nadarivatu, Viti Levu, Fiji Islands. 
It seems to me that this species is very unlike all others in 
the genus.
