The smaller and narrower size of the insect, and especially the form of the yellow spot on the pygidium (fig'.
5 h), and the rich chestnut coloured stripe on each elytron, well distinguish this species from its immediate allies.
The mentum is light chestnut coloured ; it is much angulated in the middle; the apical portion (fig. 5 a, head
seen in front, concealing the hasal portion of the mentum) being broadly cordate, the front margin being but
slightly emarginate. The middle of the thorax, in front of the scutellum, is but slightly impressed.

This species is at once distinguished by the deeply emarginated hind margin of the prothorax. The mandibles
have the outer blade considerably elongated (fig. I I a). The maxillse have the upper lobe forming a very
acute sickle-shaped tooth, and the lower lobe is acutely bidentate with several spinulose sette on the inner
margin (fig. I I 5). The mentimi is oblong, with the apical half oblique and the apex nearly truncate (fig.
l i e , II f?, the same seen sideways). The mesosternum is broad, rather rounded in front, obtuse (Eg. lI/),
and but slightly porreeted ( I I e, seen sideways). The anterior tarsi are 5-jointed, but the basal joint is concealed
above by the produced extremity of the tibia. The punctm-es on the disc of the elytra form transverse
curved lines, and they are very crowded together at the sides, the apex being marked with obhque striolie.
The pygidimn is black, longitudinally earinated down the middle with two oval convex yellow spots, striolated
at the sides, the striola? in the middle being transversely curved. The abdomen beneath is black and glossy ;
it is convex, the second and third segments with a very slight longitudinal impression in the middle. The
metasteruum is marked with a large nearly circular spot of yellow on each side (visible from above), and the
third and fourth segments have a yellow spot on each side also seen from above. The terminal pair of spiracles
of the abdomen are conically elevated.
The specimen figured in the plate was kindly forwarded to me by M. Boheman from Stockholm, where
I have also since examined other individuals.

The clypeus is convex, very slightly angulated, and elevated in the middle of the fore margin. The maxilla»
(fig. 6 a) have the galea very acute and curved, and the basal lobe is produced at its apex into an acute spine,
with another nearly as large in the middle of the inner edge; the mentum (fig. 6 i) is oblong, rounded at the
anterior angles, and but very slightly emarginate in front. The yellow colour of the clypeus extends in a
triangle nearly to the back of the head, which is nearlj^ smooth. The yellow margin of the prothorax is angulated
near the Under angles; the disc is sparingly impressed with very fine punctures, as are also the elytra,
where they scarcely form longitudinal lines. The black lateral margin of the elytra extends from the shoulders
to rather beyond the middle, where it suddenly terminates, the yellow then extending to the margin. The black
apex of the clj^tra is separated from the yellow portion by a strong elevated arched ridge, beyond which the
apex is closely covered with delicate transverse striola;, with which also the tricarinated pygidium is also covered.
The black suture of the elytra is but little depressed at the base, and is slightly raised at the extremity. With
the exception of the exposed sides of the metasternum and posterior COXEB, the under side of the body is black.
I n the large size of the tooth in the middle of the inner margin of the basal portion of the maxilla; (mando),
this species is distinguished from the majority of the genus, but agrees with Faldermann's Jf. mirahilis. The
very slight emargina.tion of the mentum is also a peculiar character. The fulvous colour of the disc of the
elytra occasionally assumes a rich more chestnut tint.
