which are directed backwards; base bisinuate, closely applied to the base 
of the elytra; apex deeply subangularly emarginate, front angles produced, 
acute, directed forwards; disk not closely punctured, acute, directed 
forwards; disk not closely punctured, the interstices not granulose, but 
sparsely finely punctulate, basal impressions as in C. elongata ; lateral ex- 
panded margins wide, a little concave, and (together with the sides of the 
disk) rather strongly reticulately rugose-punctate, the edges unequally (not 
uniformly) thickened; scutellum strongly transversely triangular, punc- 
tured: elytra convex, very dark purplish brown, the suture and narrowly 
at the base inclined to reddish; base subtruncate; disk finely irregularly 
punctured, the cost but little evident except at the base, and, together 
with the suture, smoother than the intervals ; indistinctly, except at ie s 
apex, minutely granulose; intervals between the costx irregular! 
pressed with much larger punctures, and feebly reticulately rugose, = 
distincsly so at the sides ; lateral expanded margins wide, distinctly extend- 
ing to the apex, concave, faintly punctured: underside shining a: ; legs 
and antenns dard reddish brown.

Hab. Pitt island (the Chathams.) A single example. 
Easily separable from C. elongata by the relatively broader form, ‘the 
subangulately rounded sides of prothorax, the peculiar punctuation of the 
head, etc., the much broader expanded lateral margins, which in the elytra 
' are distinctly broadly continuous to the apex. 
Cilibe humeralis, n. sp. 
Oblong or oblong-oval ; black ; elytra sometimes with a slight purplish- 
brown tinge, slightly shining, moderately convex. Head moderately punc- 
tured, the punctures not crowded, the interstices sometimes sparsely 
minutely punctulate: prothorax distinctly less transverse than in any 
preceding species, sides more or less strongly and obliquely narrowed from 
behind the middle, slightly sinuously narrowed behind ; hind angles acute, 
slightly outwardly directed; disk finely punctured, the punctures more 
crowded at the sides, the interstices not perceptibly granulose, sparsely 
minutely punctulate ; a transverse, slightly bowed, impressed line at each 
side the middle near the basal margin, and sometimes a rounded fovea at 
each side the median line near the middle of the thorax ; lateral margins 
moderately expanded, a little concave, rugosely punctured, finely and some- 
what uniformly thickened at the edges; apex deeply emarginate, front 
angles prominent, acute, directed forwards; elytra slightly emarginate at 
the middle of the base, obliquely and slightly arcuately truncated at each 
side ; humeral angle very prominent, slightly rounded, reflexed, and deeply 
concave within the angle; disk finely rugulose, studded with — granules,
