3G6 Mr. F. Bates's desci-iptions 
Adelium nigroceneuvi, sp. n. 
Oval, subdepressed, black sHglitly bronzed, very glossy : 
head rugosely punctured : protliorax ample, convex, regu- 
larly rounded at the sides, which are slightly expanded 
and rather strongly margined ; front arcuate-emarginate ; 
base closely applied to base of elytra, rather strongly tri- 
sinuate, distinctly bilobed in the middle ; hind angles 
slightly rounded, a little outwardly directed ; median 
dorsal furrow Avell marked at base, absent at apex ; some- 
what finely and irregularly punctured and rugose ; a dis- 
tinct oblong impression at each side near the middle of 
the margin, and another impression at each side the base 
at the outer sinus : elytra subdepressed, scarcely wider at 
base than base of protliorax ; sides gradually narrowed 
from before the middle to the apex ; each elytron with 9 
well-marked striae, which are minutely and indistinctly 
punctured ; intervals smooth, impunctate, subconvex 
(especially at sides and apex) ; the 4th and 8th shortest, 
exclosed by the 3rd and 5tli and 7th and 9th; the 3rd and 
7th extend to — and unite at — the margin, just before the 
apex ; epiplein-al fold normal : underside and legs bronze- 
black, shining ; the former almost impunctate ; the latter 
rather robust, feebly punctured, sparsely pilose : antennse 
stout, very gradually thicker outwardly ; 3rd joint as long 
as 3 — 4 united ; last joint elongate, ovoid : ])rosternal 
process horizontal, strongly and acutely produced behind : 
mesosternum prominent, broadly concave thronghoiit its 
length : intercoxal process very wide ; apex squarely tnui- 
cated : last joint of antennre, and the tarsi, fulvous.

Hob. — New Caledonia. One example. 
By the form of the prosternal process, mesosternum, and 
the trisinuate base of prothorax, the present species will 
form the type of a new section of the genus. The pro- 
thorax is disproportionately large. It might Avell be the 
Adelium exul of Montrouzier ; but he gives eight strife only 
to each elytron, the intervals as slightly rugose, and the 
legs as " presque greles." 
Adelium Fairmairei, n. sp. 
c??. — Oblong-oval, depressed, dark bronzy-brown, shin- 
ing : head and prothorax irregularly punctured and indis- 
tinctly foveolate and rugulose : prothorax wider tlian long, 
depressed, arcuate-emarginate in front, and slightly com-
