The species of tins genus differ from all the rest of the sub-family in their variegated colours as well as in
the shape of their robust bodies, which bear a greater resemblance to the ordinary form of the typical Cetoniidai.
The species are natives of Africa and the East.

Dr. Schaum (in a letter to me of October 28, 1848) says : ' I have lately obtained two specimens of Macroma
Aii/ssiaica, and seen about a dozen more in the Senkenberg Museum, in Frankfm-t, taken by Riippel. I have
compared them very earefuUy with my specimen of Macr. conftisa, Hope [sculellaris, Gor. et Perch.), from
Senegal, and do not find any difference. Macroma Ahjssinica must therefore be sunk. I have no doubt, by
comparing Mr. Hope's specimen of confusa with that of Äbyuinka in the British Museum, you will comc
to the same conclusion.' The specimens from Abyssinia, to which I applied the MS. name M. Ahi/ssinica,
are smaller than all the others from South Africa, Natal, and Zulu, being only lines long. I can, however,
discover no other specific distinction.

No flg'ure has hitherto been published of this pretty species.
The basal joint of the antenna is rather dilated. The apex of the clypeus is emarginate, having a transverse
elevated line close to the apex. The maxilla (fig. 3 a) in both sexes has the inner lobe armed with three
teeth, of which the upper one is the largest, and the inner one scarcely prominent. The mentum (alike in both
sexes) is emarginate on each side opposite the insertion of the labial palpi (fig. 31), and the anterior tibia of the
male (fig. 3 c) is narrower and less strongly toothed than that of the female (fig. 3 cl).

Dr. Schaum says of this species in the French Annales, 1844, where he first applied to it the name of
Macroma snlcicollis, 'l'espèce que j'avais regardée (Germar Zeitschr., 1. c.) comme étant la Macroma scutellata
des auteurs est plus grande, plus large ; elle a la tête noire avec une bande transversale au milieu et une
tache y-jointe qui occupe tout le vertex, jaunes ; le corselet est sillonné au milieu dans toute sa longueur et n'a
pas des points enfoncés sur les côtés.'
