Tliis species is larger than the true G. caslanam, with a very distinct white spot on each elytra; the head
and thorax are densely and finely punctured; the sides of the thorax are attenuated from the middle towards
the apex. Mr. Kirby's type specimens are in the liopeian Collection.
' This is the insect which I described as Castaneffi; believing that the original specimens of Knoch existing
in Berlin belonged to this species. I had, however, no opportunity of comparing both together. Burmeister
has followed me.' (Schaiim in letter of January 9, 1848.)

The head is small, convex, thickly covered with minute punctures, with the fore margin strongly reflexed
and sharp; rounded as seen from above, but arched upwards (or emarginate) as seen from the fi-ont. I he
mentum is very deeply notched in the middle behind. The prothorax is transverse, opaque, less thickly covered
with setose punctures than the head, with a very slight longitudinal impression down the centre. The anterior
ano-les are porrected, glossy, bkek, curved inwards towards the eyes; the sides of the prothorax ai;e emarginate
behind the andes, and are thence curved gradually outwards, the widest part being slightly beyond the middle;
the posterior lateral angles arc acute, conical, glossy, black, rather elevated and directed outwards towards the
shoidders of the elytra ; the sides of the pronotum within the lateral posterior angles are rather deeply impressed.
The elytra are wider than the prothorax, opaque, rather thickly covcred with oval cicatricose pimctures emitting
slender luteous seta;; each elytron with a small transverse not veiy distinct luteous mark near the lateral margin,
beyond the middle ; the disc of each is depressed. The pygidium is covered with mmiite luteons sete
. This species (undescribed by anybody else than Knoeh) is of the size of C. vanolosu.s; the white spot on
the elytra is scarcely visible (and therefore not described by Knoch); the head and thorax sparsely and grossly
punctured ; the thorax broadest immediately before the hind angles, and gradually narrowed towards the apex
This is the true Castanet of Knoch, D. Melsheimer having a specimen in his collection which was transmitted
by Kuoeh to his father. Both species have the canalicnla of the thorax, but they are sufficiently distinct.
KuocVs figure of the thorax of Cr. caeiane^ is pretty correct. I was led into the belief that C;-. o a n a kMs
was the true Cr. carianecs by the Berlin Museum, where Or. canaliculatu, ^^^ considered as synonymous with
Knoeh's insect; and, moreover, by the occurrence of the two principal characters of Cr. oanahcMus, viz. the
white spot and the eanaliciilation of the thorax. The doctrine to be derived is, that we have to learn every
day.' (Schaum, in letter of January 9, 1848.)
