36o APPENDIX. 
Family Melolonthid/e. 
Of this family a number of small obscure-coloured species were also 
collected, with two species of Trox ; but of the very characteristic 
genera Anisonyx, Pcritrichia, Lepit7'ix, Pachycnevia, Dic/ieliis, Moiio- 
chelus, and Gyninoloina, all very numerous in species, and peculiar to 
South Africa, no specimens were captured by Mr. Gates. 
Family Dynastid^E. 
Oryctes Boas, Fabricius, and a small Syrichthus, allied to S.ga^ates, 
were the only Dynastid^ captured ; the former in large numbers. 
Family CetoniiDvE. 
Of the family of the Rose Chafers (Cetoniid^e), containing about 
looo described species, twelve genera are peculiar to Western Africa, 
fourteen to South Africa, and twenty-one to Madagascar. Of the 
gigantic species of Goliath beetles, Goliathiis albo-signatus, Boheman 
{Kirkii, G. R. Gray), inhabits the Zambesi country. Ceratorhina 
sple7idens, Bertoloni {Petersiaiia, Klug), one of the loveliest and most 
remarkable of beetles, inhabits the Tati district and Mozambique, 
but none of these singular insects were found by Mr. Oates. Six 
species of Cetoniid^ were taken by Mr. Oates, including Pachitoda 
obsoleta, Schaum ; Spilophoriis plagosus j Phoxomela Jimbrosa, Gory 
and Perchdron ; and OxytJiyrca discicollis, Reiche, and hcemorrhoi- 
dalis, Fabricius. 
Family LUCANID^. 
Of this family there are ten genera in South Africa, seven of which 
are peculiar, and two of these are confined to the Island of Bourbon ; 
two genera are peculiar to Western tropical Africa and three to South 
Africa ; whilst the otherwise widely- ranging genera Lncamis and 
Dof%-?is are absent from Africa. No species of this family was taken 
by Mr. Oates. 
Family Buprestid^. 
This family is very extensive, containing at least 2700 species, 
many of which are splendidly coloured insects, of gigantic size, amongst 
which is a group essentially African, remarkable for the numerous 
pencils of short erect hairs dotted over their whole upper surface 
(Genus Julodis, Eschscholtz). The species of Steraspis and Ster- 
nocera are also of large size and great brilliancy. Twenty-seven genera 
of these insects occur in South Africa, of which six are peculiar, but 
Mr. Oates only collected four small and obscure species. The singular 
Genus Polybothris, with widely dilated elytra, is peculiar to Mada- 
gascar, no species of the genus having been found on the African 
continent.
