rather closely and finely but irregularly punctured, the punctures largest 
and most crowded (and frequently, especially at the base, more or less run 
together, forming indistinct irregular foveze) between the costz ; these very 
indistinct ; expanded lateral margins rather broad at the base, gradually 
narrowing behind and scarcely extending to the apex, concave in their basal 
portion: underside shining, pitchy black; legs and epipleural fold with a 
reddish tinge ; flanks of prothorax and sterna more or less strongly reticu- 
lately rugose and granuldse; antennz, palpi, and labrum (sometimes) 
ferruginous ; anterior border of epistoma rufescent. 
Length 54-6 lines ; width of elytra across the middle 22-3 lines. 
Hab. New Zealand. Four examples. 
_ AntheFem. ? the form is slightly more expanded, the prothorax slightly 
more transverse, the sides less strongly narrowed anteriorly, and the punc- 
tuation of the elytra a little more open. 
The three species last described are very near to each other, but I think 
there is ample justification, at present at least, in holding them distinct. 
The species last described is of a more oblong form (especially in the 
Mas. ?) than the others; the prothorox has not the same glossy blackness 
as in elongata ; and the elytra are less opaquely roughened, more closely 
punctured, and much less distinctly granulose ; the humeral angle is much 
more prominent, the lateral expanded margins broader and strongly concave 
within the humeral angle. From pascoet it may be known by its narrower 
and more oblong form, finer and closer punctuation, and more narrowly ex- 
panded lateral margins. 
Cilibe thoracica, n. sp. 
In this species the prothorax is still more decidedly elongated (but is yet 
wider than long) than in the preceding. Form elongate-oval; entirely in a 
dark brownish black, subopaque. Head and prothorax (save on the middle 
of the disk) closely punctured, the punctures rounded, a little more 
crowded at the sides of the latter, the interstices distinctly punctulate ; 
sides of prothorax gradually and but slightly curvedly narrowed from near 
the hind angles to the apex, distinctly incurved at the hind angles, which 
are more produced than in humeralis, and slightly convergent or directed 
inwardly ; apex deeply emarginate, front angles subacute, slightly con- 
vergent ; expanded lateral margins moderately wide, scarcely concave, the 
edges finely and almost uniformly thickened; a rather slight sublunate im- 
Pression at each side of the middle, close to the basal margin, and another 
still less distinct, rounded fovea above and in front of them; scuttellum 
transversely triangular, punctured; base of elytra as in C. humeralis, the 
humeral angle still more produced (but not strongly concave within the 
angle), sides with a very distinct sinus behind the humeral angle; disk
