Of the sacred beetles, SCARABÆIDÆ, eminently characteristic of Africa, and especially of the southern region, specimens of the gigantic _Pachylomera femoralis_, Kirby, and a _Heliocantharus_, the largest species of the genus, were taken by Mr. Oates, together with _H. transversus_, Laporte (_operosus_, Dejean), and _H. intricatus_. _Circellium Bacchus_, _Chalconotus cupreus_ (varietas minor et brevior); three charming species of _Gymnopleurus_, _G. Olivierii_, _fulgidus_, and _speciosus_; _Sisyphus_, one small species; _Copris_, eight species, including _C. Jachus_, _Œdipus_, _Nemestrinus_, and _cœlatus_; six small obscure species of _Onthophagus_; _Onitis inuus_ and _ciliatus_:--the preceding, of all of which specimens were taken, together with several small obscure species of _Aphodius_, all being coprophagous in their habits, sufficiently testify to the existence of numbers of large mammalia in the regions where they occur. Family MELOLONTHIDÆ. 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_, _Peritrichia_, _Lepitrix_, _Pachycnema_, _Dichelus_, _Monochelus_, and _Gymnoloma_, all very numerous in species, and peculiar to South Africa, no specimens were captured by Mr. Oates. Family DYNASTIDÆ. _Oryctes Boas_, Fabricius, and a small _Syrichthus_, allied to _S. gagates_, were the only DYNASTIDÆ captured; the former in large numbers. Family CETONIIDÆ. Of the family of the Rose Chafers (CETONIIDÆ), containing about 1000 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, _Goliathus albo-signatus_, Boheman (_Kirkii_, G. R. Gray), inhabits the Zambesi country. _Ceratorhina splendens_, Bertoloni (_Petersiana_, 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 CETONIIDÆ were taken by Mr. Oates, including _Pachnoda obsoleta_, Schaum; _Spilophorus plagosus_; _Phoxomela umbrosa_, Gory and Perchéron; and _Oxythyrea discicollis_, Reiche, and _hæmorrhoidalis_, Fabricius. Family LUCANIDÆ. 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 _Lucanus_ and _Dorcus_ are absent from Africa. No species of this family was taken by Mr. Oates. Family BUPRESTIDÆ.
