of neiv genera and species of Tenehrionidce. 357 
— except at apex — bvit not very closely punctured ; under- 
side metallic green variegated with coppery, purple, &c. ; 
legs, antennas and palpi entirely testaceous-yellow. 
In the $ the entire punctuation is stronger and closer, 
the pro- and meso-tarsi are dilated, and the size is smaller. 
Long. 7^ to 9 lin. ; lat. elytr. 3^ to 4 lin. 
Hab. — Queensland ? Four examples. 
Very distinct from O. (^Adelium) cupreus, Gray; which 
has the prothorax wider — and scarcely sinuously emargi- 
nate — in fr-ont ; the sides more rounded, more expanded, 
flatter, broadly testaceous, and nearly smooth, and the disk 
impunctate : the elytra more gibbous, very faintly and 
remotely punctulate, the reflexed margins reddish-testa- 
ceous ; and the legs, antennas and palpi reddish-testaceous, 
with the apex of the femora broadly cyaneous. 
Apomesteis, n. g. 
Mentum trapezoidal, convex : maxillary palpi wanting : 
eyes rather large, not prominent, fr-ee : epistoma short, 
slightly — and broadly — emarginate in front, the sutiu'e 
strongly marked : antennary orbits long, sides subparallel : 
antenna moderate, joint 3 elongate, 4 — 7 subequal, sub- 
cylindric, or elongate-obconic, 8 — 10 gradually shorter, 
strongly obconic, 9 — 10 scarcely transverse, 11 large, 
rounded at apex : prothorax depressed, transverse, strongly 
emarginate in front, angularly so at each side, anterior 
angles moderate, scarcely produced, subacute, a little de- 
pressed, slightly outwardly directed;' sides very slightly 
narrowed fi'om the base to before the apex, thence more 
rapidly incurved, the edges thickened ; base rather strongly 
bisinuate : scutellum broad, rounded behind : elytra Avider 
than prothorax ; base sinuous ; shoulders convex, the 
angles rounded ; iiTCgularly convex, the greatest convexity 
before the middle, thence gi-adually declivous to apex ; 
sides irregularly expanded at the margins, very finely 
bordered ; apex narrowly rounded ; e-pipleural fold very 
gradually narrowed behind : prosternum rather short, 
strongly compressed, carinate, the apex produced ; its 
process prominent behind, compressed, lanceolate : meso- 
sternum A^ertical in front, very strongly, deeply and Avidely 
excavated : inter coxal process wide, apex broadly rounded : 
legs rather stout ; femora faintly emarginate on the inner 
edge, from near the apex ; the anterior with a short tooth.
