In Carabidæ or carnivorous ground beetles, there are about 75 peculiar genera. Among the most characteristic are _Anthia_, _Polyrhina_, _Graphipterus_ and _Piezia_, which are almost all peculiar; while _Orthogonius_, _Hexagonia_, _Macrochilus_, _Thyreopterus_, _Eudema_, and _Abacetus_ are common to this and the Oriental region; and _Hypolithus_ to the Neotropical. Out of 27 genera of Buprestidæ, or metallic beetles, only 6 are peculiar to the region, one of the most remarkable being _Polybothrus_, confined to Madagascar. _Sternocera_ and _Chrysochroa_ are characteristic of this region and the Oriental; it has _Julodis_ in common with the Mediterranean sub-region, and _Belionota_ with the Malayan. The region is not rich in Lucanidæ, or stag-beetles, possessing only 10 genera, 7 of which are peculiar, but most of them {257}consist of single species. The other three genera, _Cladognathus_, _Nigidius_, and _Figulus_, are the most characteristic, though all have a tolerably wide range in the Old World. In the elegant Cetoniidæ, or rose-chafers, this region stands preeminent, possessing 76 genera, 64 of which are peculiar to it. The others are chiefly Oriental, except _Oxythræa_ which is European, and _Stethodesma_ which is Neotropical. Preeminent in size and beauty is _Goliathus_, comprising perhaps the most bulky of all highly-coloured beetles. Other large and characteristic genera are _Ceratorhina_, _Ischnostoma_, _Anochilia_, _Diplognatha_, _Agenius_, and many others of less extent. In the enormous tribe of Longicorns, or long-horned beetles, the Ethiopian is not so rich as the other three tropical regions; but this may be, in great part, owing to its more productive districts having never been explored by any competent entomologists. It nevertheless possesses 262 genera, 216 of which are peculiar, the others being mostly groups of very wide range. Out of such a large number it is difficult to select a few as most characteristic, but some of the peculiarities of distribution as regards other regions may be named. Among Prionidæ, _Tithoes_ is a characteristic Ethiopian genus. A few species of the American genera _Parandra_ and _Mallodon_ occur here, while the North Temperate genus _Prionus_ is only found in Madagascar. Among Cerambycidæ, _Promeces_ is the most characteristic. The American genera _Oeme_ and _Cyrtomerus_ occur; while _Homalachnus_ and _Philagathes_ are Malayan, and _Leptocera_ occurs only in Madagascar, Ceylon, Austro-Malaya, and Australia. The Lamiidæ are very fine; _Sternotomis_, _Tragocephala_, _Ceroplesis_, _Phryncta_, _Volumnia_, and _Nitocris_, being very abundant and characteristic. Most of the non-peculiar genera of this family are Oriental, but _Spalacopsis_ and _Acanthoderes_ are American, while _Tetraglenes_ and _Schoenionta_ have been found only in East and South Africa and in Malaya.
