376 Mr. F. Bates's descriptions 
bronzy-green with the base violet, or purplish-violet, and 
the suture more or less broadly dark green, punctate- 
striate, the striaj very faint even at the sides, the punc- 
tures minute at the sides, obsolete at the apex ; intervals 
minutely punctulate, flat, the 7 th only feebly convex at 
the extreme apex : underside and legs shining pitchy- 
black, palpi and antennae dark chestnut-red : prosternal 
process broadly triangulate behind : mesosternum very 
prominent, broadly and somewhat angularly notched in 
front, and produced at each side : intercoxal process wide, 
apex very broadly triangulate. 
Long. 4^ to 4^ lin. ; lat. elytr. '2\ to 2| lin. 
Hah. — New Caledonia. Three examples. 
Var. Smaller. Long. 3;^ to 3|^ hn. Disk of prothorax 
slightly rugulose. 
JIah. — New Caledonia. Two examples. 
This species is easily to be distinguished from all the 
others by the disk of the prothorax foveate-pimctate. I have 
received it from Paris, and have also examples out of the 
Coll. Done, as the 1. convexus, Montrouz., but this is 
manifestly Avrong, his description clearly gives tlie whole 
surface of a brilliant black, and as having a scutellum. 
Isopus Allardi, n. sp. 
Briefly oval, shining, head and prothorax dark olive 
green, elytra purplish-violet with slight greenish reflections, 
the basal half of the suture green : head above entirely 
finely and not closely punctured : prothorax moderately 
convex, feebly depressed at the middle of the base, sides 
gradually, and scarcely curvedly, narrowed fr-om base to 
apex, apex strongly emarginate, the angles acutely pro- 
duced and directed forwards ; moderately punctured on the 
disk, the punctures near the base a little larger (but by no 
means foveate) and more scattered, those on the sides very 
minute : elytra very convex, but more gradually declivous 
behind than in those preceding, but little wider at base 
than base of prothorax, sides gradually narrowed from 
before the middle to the apex, which is strongly produced 
and very narrowly rounded ; jjunctate-striate, the stria3 
more distinct than in rohustus ; the 7th, 8th and 9tli in- 
tervals as in Blanchardi : underside and legs very glossy, 
pitchy-black with a slight greenish tinge on the meta- 
stcrnum and abdomen : coxa; and palpi glossy light chest- 
nut-red, basal joints of antennae and tarsi a little darker :
