dans la seconde année de ces Etudes, p. 4'7. Depuis ayant eu l'occasion de me procurer des exemplaires plus
complets., je me suis assuré qu'il n'appartient guère à ce genre, par plusieurs caractères très remarquables, tels

arrondis, et enfin, par des tarses postérieures composées seulement de qiialre articles visibles, vu que le tier est
oblitéré et entièrement soudé au seeoud, n'étant représenté que par nn renflement globuliforme assez insignificant,
à la base de ce dernier, parfaitement caché dans la cavité de la jambe. Cette Cétonide est donc hétéromère'
GENUS 14^CENTR0GNATriUS.
(Guérin-Méneville, Rev. Zool. 1S40, p. 79; Scliaum. Germar Zeitschr. iil. 267.)
Corpus latum crassum. Caput parvum. Cljqieus apice subsinuato margine reflexo et in cornu clavatum
elevato; lateribus supra basin antennarum auriculatis (fig. 4ff, caput e latere visum). Antenna; articulo basali

ambiente (fig. 4 b). Masilloe parvie galea uncinata apice acuto integro ; mandonis dente apieali curvato apice
fisso (fig. 4c). Jlentum oblongum subparallelum, in medio disci angulatum, parte antica oblique troncata,
margineque antico fere recto (fig. id). Prosternum inerme, nee ante eoxas anticas spina armatum. Mesosternura

The genus is here confined to the single species first described by Guérin-Méneville as its type, and which
differs from the allied species, "with which I have formed the Genns Spilophorus (which Burmeister united with
it) in the remarkable structure of the head and leg-s. In its eibarian characters it more nearly agrees with them.

I have hitherto only seen a single specimen of this curious species, now in Major Parry's collection. The
lateral margins of the head are raised into two auriculated processes, and the front of the clypeus is raised into
an erect subtruneated horn (fig. 4«, head seen sideways). The mandibles (4i) are pointed at the tip, with a
setose membranous lobe on the inner margin, of which the base is not much produced ; the galea of the maxillic
(fig. 4 c) is acute, and the mando bidentate. The mentum is oblong, straight in front, and rather constricted in
the middle on each side (fig. 4i?). The legs are very short and thick (fig. the anterior tibia and tarsus),
the latter being 5-jointed. The frontal horn is polished in front. The prosternum is entirely simple, and not in
the least prominent, nor with a defiexed point in front of the anterior COXIE. The podex is semicircular, with a
very slight longitudinal central carina.

This genus is now composed of several species from South Africa and India, remarkable for their general
resemblance to some of the robust species of Cetonia;, and for the brilliant shining upper surface of the bodies
more or less marked with white or bufi^ patches.

The specimen of this species, 14 mill, long, figured in pi. IX, fig. 6, was (with another only ll-J mill, long,
but agreeing with it exactly) brought from South Africa by the late Dr. Burchell, both difirering from the
ordinary type in the much smaller extent of the white markings ; the head and pronotum being entirely black,
the latter with the sides (especially near the posterior angles) punctured, with a very minute spot close to the
outer margin of the elytra near the apex, and a very small one on each side of the pygidium ; the under side of
the body is also quite immaculate.
The maxillie (fig. 6 a) have the galea sickle-shaped, but rather thickened in the middle; the mando has a
small tooth on the under side; the mentum is oblong, with the fore margin scarcely emarginate, the lateral
margin slightly narrowed in the middle for the action of the labial palpi (fig. 6 b); the fore legs are strongly
bidentate on the outside (fig. 6 c).
The specimens described by Burmeister and Boheman have the hind part of the head marked with an
irregular white transverse mark, the sides of the pronotum with a broad white band, irregular on its inside, and
not extending to the hinder angles; the sides of the elytra marked in the middle with a large irregular spot,
within which are several black dots, the apex of the elytra with a transverse irregular white broken spot, and
