The polished surface of this insect, and the peculiar form of the prothorax, well distinguish it from its
congeners. It bears indeed a certain amount of resemblance to some of the species of Cymophorus, but the
very acutely bidentate galea of the maxillffi (fig. 1 a), and the great length of the bidentate terminal spine of
the mando, prevent its introduction into that genus. The elytra are t\\'ice the length of the widest part of tlie
prothorax; the four posterior tibi^ are longitudinally sulcated, and there is a fine impressed line down the
middle of the meiasterniim.

This very small narrow species is at once distinguished by the raised tubercle in the middle of the head, between
the eyes, and by the somewhat oval prothorax having a large oval impression in the middle of its upper side. The
head is rather short, the elypeus broad, with the fore margin slightly emarginate in the middle. The prothorax
is broader than the head, the sides rounded, the greatest width being about the middle of its length.
The anterior angles are not prominent, but the posterior ones are acute, and the hind margin is slightly emarginate
in front of the scntellum. The elytra are very narrow. The head is punctured rather strongly and closely,
as is also the front of the pronotum, with the punctures circular, but behind the middle the punctures are more
linear, and so arranged as to form two oval circles. The elytra are punctured, the punctures emitting luteous
setie, those on the basal half of the elytra being sometimes more or less confluent, forming two or three illdefined
abbreviated strife in addition to the two decided strise on each side of the suture. The posterior spiracles
form two very minute conical points. The legs are rather robust, the anterior tibi£e, in the only specimen I
have seen, broad and bidentate, the tarsi flattened, with the joints dilated, only the three apical joints being
visible from above in the anterior feet. The prosternum forms a strong deflexed spine in front of the fore cox®.
The abdomen is convex beneath. On the under side the body is black and glossy, punctured, and setigerous,
as are the top and under sides of the prothorax.

This species is distinguished by its convex head and prothorax, the latter nearly as broad in the middle as
the elytra, with the hind part wider than the front, and by the very broad bidentate tibia:. The cly[)eus is rather
dilated on each side into a flattened lobe, with the margin slightly reflexed, the fore margin being emarginate
in the middle. The prothorax is broadest across the middle, with the sides rounded, the anterior portion being
much more gradually narrowed than the hinder, which latter has the posterior lateral angles aeute and slightly
produced in front of the epimera ; the disc is convex and entire, but there is a transverse impression on eacli
side of the base; the punctures on the front of the prothorax are simple and round, but in the middle and
hind parts they are more oblong, closer, and more confluent, becoming short striol® near the posterior angles.
The elytra are very long and narrow ; they are shining and very debcately and irregularly punctured; they have
a moderately prominent costa at a short distance from the suture, the sntural stria being curved and duplicated
beyond the middle of the elytra; on the disc are three duplicated strite, which are abbreviated behind, the
lateral one not extending to the middle, behind which is a longitudinal impression parallel with the lateral
marn-in. The two terminal spiracles are conical and prominent; the legs are rather short and strong, with the
tibia! broad, the anterior being strongly bidentate ; the podex is very convex and semicircular; the body beneath
is black and very glossy; the abdomen in the only (lemale) specimen which I have seen not being channelled.
The deflexed sides of the pronotum are marked with curved strife, and all the femora on the under side and the
sides of the metasternum are similarly striated.

The small size and narrow form of this species, with an oblong prothorax somewliat swollen across the
middle, distinguish it from the other species. It is black, slightly glossy ; the head and pronotum covered with
minute circular punctures; the reflexed lateral margins of the latter marked with close curved longitudinal
strife ; and the hind margin is nearly straight, being scarcely emarginate in front of the seutellum, which is transversely
striolated at the base and punctured behind. The elytra are very delicately punctured, and each is
marked with five very fine duplicated stria; ; on each elytron, beyond the middle, there is a longitudinal
impression parallel with the lateral margin. Each of the two maxiUary lobes are acutely bidentate; the mentum
is oblong, rounded in front, with a notch in the middle of the fore margin (fig. 6 a). The anterior femora
are longitudinally striated on the under side. The middle of the metasternum is punctured, and its sides
marked with curved longitudinal striai placed close together. The abdomen beneath, especially at the sides,
is finely but irregularly striolated ; the pygidium is terminated by an obtuse point, and is marked with very
delicate cn-cnlar striolce.

The mando of the maxillai is acutely bidentate ; the inner edge below the teeth armed with several strong
spinose setic. The galea is also acutely bidentate ; the mentum (fig. 8 a) is oblong, rather widened in front,
where it is obhqnely truncate ; the posterior margin of the oblique truueation clothed with strong erect set®. The
elytra are marked next the suture with a stria formed of a fine double impressed line extending from near the
extremity of the seutellum almost to the pygidium: a second similarly formed stria is more abbreviated both
