The Neomida sulcata (elongata), Montrouzier (sec. Coll. 
Done), will enter into this genus. 
Chlorocamma carenipennis, n. sp. 
Larger than Sulcata, Montr. : head black, epistoma 
more closely punctured, front densely, reticulately rugose- 
punctate ; prothorax greenish-black and moderately shin- 
ing — or metallic — green, with pale purplish reflections, and 
more or less closely punctured, according to the sex?: 
scutellum shining black ; elytra deeply striated, or sulcated, 
the strias distinctly punctured at bottom ; intervals dis- 
tinctly pimctured, convex — strongly so at sides and apex ; 
the 3rd, 5tli and 7th are most strongly and distinctly cari- 
nate behind ; the 3rd ounces inwards to the extreme apex 
and encloses the 1st and 2nd; the 5th and 7th luiite be- 
hind, and enclose the 6th ; sometimes the 4th and 7tli and 
5th and 6th ap})car to be united in pairs behind ; the colovir 
is of a dark green, shining, the base and suture pnx'])le ; 
miderside deep shining black, with slight metallic reflec- 
tions on the metasternum and abdomen ; flanks of prothorax 
more or less coarsely — but not closely — rugose-punctate ; 
pro- and meso-sterna, prosternal process, and base of meta- 
sternum, coarsely and closely rugose-punctate ; underside 
deep shining black ; legs pitchy ; antennaB, palpi and tarsi 
ferruginous.

Hah. — New Caledonia. Two examples. 
In both the present species and in C. sulcata the form 
that I take to be the $ is more broadly oval ; the pro- 
thorax distinctly wider, more brightly coloured, and more 
finely and sparsely pimctured. 
The present species may at once be distinguished from 
sulcata by the larger size, and the head densely and 
reticiJately rugose-punctate on the front. 
Episopus, n. g. 
Very near to Isopus, but of a more regidarly oval and 
much less convex form ; legs a little shorter and stouter, 
\\h\X: more thickened outwardly and more compressed ; 
eyes smaller ; scutellum small but very distinct, triangular;
