The extraordinary size of the first joint of the antennas, the very large mentum, and the 4.-jointed tarsi
in all the feet of both sexes, will at once distinguish the species of this genus, which is essentially Oriental.

I suppose the two specimens of this curious spceies which I have seen are males, because the second and
third segments of the abdomen are slightly longitudinally depressed on their ventral surface. They have,
however, the tarsi 4-jointed with very small ungues. The maxilla have the outer lobe forming a slender very
acute curved hook, and the inner lobe is obliquely truncate and sharp (fig. 6 a). The mentum is somewhat hexagonal,
being widest at the anterior lateral angles ; it covers the whole of the front of the under side of the head. Its
inside is represented in fig. 6 b, shewing the small size of the labial palpi, the labium itself forming two setose
diverging lobes, Ijang flat on the inner surface of the mentum, arising slightly below its centre. The prosternai
point is porrected in front of the anterior coxEe. Tlie basal joint of the antenníE is very large, flat, and subtriangular,
with the anterior angles rounded, it exactly closes the space between the eyes and the mentum,
forming a continuous flat surface with the latter.

The colours of this pretty species, and the flat surface of the elytra shewing only the vestiges of longitudinal
striobn visible in the two slender paler-coloured longitudinal lines, will at once distinguish it. The protliorax is
also comparatively small, and nearly circular. The basal joint of the antenniB is very large, and triangular;
when at rest it shuts exactly between the sides of the mentum and the eyes, completely concealing the sides ot the
head beneath • the second joint is inserted on its inner surface below the middle (fig. 7 a). The mentum is very
laro-c formino- a covering, indeed, for the under side of the greater part of the head (fig. 7 Í ) ; it is angulated in
the"middle of its basal margin, in the front of which it is dilated into a dcflexed horn when seen laterally
a\a. 7 c) The inaxillEE have the apical lobe formed into a slender sickle-shaped hook, the lower lolie being
broader and obliquely truncate ; the labial palpi (fig. T d) have the terminal joint curved. The anterior tibioe
have a very slight tooth on the outer edge. All the tarsi are 4-jointed (fig. 7 e, extremity of anterior tibia
and tarsus ;" fig. 7 / , the same of posterior leg). The sides of the elytra and the exposed margin of the sides ot
the metasternum are clothed with luteous piibescenee. The abdomen beneath is convex, the basal segments not
being channelled longitudinally.

This species is of a leaden-black colour, slightly glossy above, thickly but not strongly punctured, the
punctures of the elytra being oval and cicatricose. The head (fig. 8, i, seen sideways, and fig. 8, 3, froni beneath)
is broad but not dilated in front of the insertion of the antennae; the fore margin is slightiy reflexed, the disc
of the head is depressed, but the space between the eyes is more elevated. The mentum is very large, and
marked with fine circular lines ; it is produced at the middle of its base into a deflexed spine, as is also the
anterior margin of the prosternum; the maxilloe have the imier lobe narrower and less obliquely truncate than
in the two preceding species (fig. 8, 3). The labial palpi are slender, and do not extend beyond the edges of the
mentum (fig. 8, 4). All the tarsi are 4-jointed. The length of the elytia and podex is equal to H of the base of
the elytra. Beneath glossy black, with but few distant punctures. The anterior coxaî are luteous.

(Motschulsky, Etud. Eut. 1857, p. 112.)
The following is the description given by Motschulsky of an insect which seems closely to resemble Callynomes
mandarinus ; but, as it appears that its author had various individuals before him agreeing m having only
the posterior tarsi 4-jointed (for had the four anterior been in that condition he would certainly have noticed it)
and as his description of the mentum, ' élargi antérieurement et rebordé,' does not agree with my species, I
am induced for the present to consider them as distinct.
' CBEMASTOCHILA SCABEOSA.
