niiiiulo of equLil size. The meiitum is oblong, scarcely coDstrictcd in the middle, and with the fore margin
s l i g h t l y angularly emarginale. The prolhorax is obcordate, narrowed iu front, the sides gradually rounded,
the widest part being behind the middle, the hinder angles rounded olF, and the hind margin nearly straight.
There is a slender impressed longitudinal line down the middle of the pronotum, the hinder margin of which
is also marked with two transversely ovate impressions; the prosternum is armed with a strong spine in front
of the fore legs, and there is a smaller acute one in front of the mesostcrnum (fig. 9 a). Each of the elytra is
marked with six longitudinal striai not reaching to the base or apex, the interstices rngosely punctured or subgranulated
and setose. The spines of the legs are strong and acute.

The front margin of the clypeus is sl ightly emarginate ; the maxill® have both the mando and galea armed
w i t h two nearly equal thick teeth (fig. 7 a) ; the meutum is subquadrate in its outline, but the middle of the
disc is strongly ang-ulated (fig. 7 h, seen from beneath ; fig. 7 0, seen laterally) ; the obliquely truncate anterior
portion semicircular, and fringed with strong setse. The exposed part of the epimera of the mesothorax is
clothed with whitish pile, as are also the lateral parts of the metathoraeic epimera, with a large patch on each
side of the metasternum., and a spot on each side of the second and third segments of the abdomen, those on
the third being smaller than the others. The under side of the abdomen is not longitudinally channelled at
the base, and the anterior tibiie are obtusely bidentate (fig. 7 d).

The maxillse bave the mando terminated by a short transverse acutely bifid spine ; and the galea is of large
size, nearly sickle-shaped, and terminating in two acute spines. The mentum is cup-shaped, transversely
truncate at its front margin, which is vertical (figures 8«, 8c, and 8(7, seen in different positions). The
prosternum has a deflexed spine in front. The anterior coxaa arc dilated with a broad emarginate depression in
front, the produced basal angle with a large impressed puncture. The fore legs have the tibiie rather narrow
and slightly arched outwardly, with the apex rather broad and bidentate ; the tarsi are rather short in the fore
legs. The elytra have the sutural margin slightly depressed; between the suture and the middle of the disc
are four punctured, longitudinal striiE wi t h the interstices rather raised and archcd, and finely punctured, adjoining
the third stria (and between it and the lateral margin) is a fourth abbreviated stria, the punctures of these stri®,
being acicnlated and semiovai, open behind, the lateral margin thickly covered with small oval punctures. The
hind tarsi are moderately elongate, each joint marked wilh a large oblong puncture. The unguiculi of all the
ieet are small.

The acuminated and costated elytra, with the peculiar form of the anterior tibiffi, well distinguish this
species, especially from C. trabecula.
The clypeus is not refiexed at its fore margi n (fig. 4 a), which is slightly emarginate. The maxillse (fig. 41 )
have the galea moderately long and bidentate, and the mando is short, and notched at its tip. The mentum is
oblong, rather narrowed across the middle (fig. 4 c), rather deeply notched in the middle of its fore margin, the
angles of which are rounded; the disc is rather slightly longitudinally impressed, forming only a very slight
angle before the middle. The prosternum is armed before the anterior coxas with a deflexed spine, setose in
front (fig. 4 a). The anterior tibiffi, in some specimens (fig. 4f/), terminate in a broad flat lobe, rounded and
entire on its outer edge, but in others the outer edge of this lobe has a more or less distinct angular incision
(figs. 4(5 and 4/) . I presume that the former are males, and the latter females, although in all the abdomen is
convex beneath; in those, however, mt h the entire tibia, the pygidium is convex, but in the others it is rather
flattened in the middle, with a very shghtly-defined longitudinal carina. The anterior tarsi have the five joints
marked with an impressed line. The elytra, wdien seen with a lens, are delicately shagreened, being, except at
the base and along the raised costa? (which are more regularly punctured), entirely and thickly covered with
minute short lines, either straight or angulated, amongst which a few more distinct punctures are to be seen.

This species is distinguished by its convex head, nearly circular prothorax, short legs, and prominent
posterior spiracles. The clypeus is dilated at the sides, and rounded in front. The head is convex, and thickly
but very finely punctured (fig. 6 a); the fore margin is not refiexed. The maxillaj have the galea large and sickleshaped,
with two very sharp equal spines; the mando is smaller, the under tooth being smaller than the upper
(fig. 6¿). The mentum is obtriaugular, being widest and truncated in front, where it is thickened into a transversely
triangular mass, the apex of which is concave (fig. 6 c, the mentum seen from beneath ; 6 d, seen from
within, shewing the palpi concealed from above by the dilated sides of ihe mentum; 6 e, the mentum seen
