The Lucanidæ are few in number, and all have African affinities. Madagascar is very rich in Cetoniidæ, and possesses 20 peculiar genera. _Bothrorhina_, and three other genera belonging to the _Ichnostoma_ group, have wholly African relations. _Doryscelis_ and _Chromoptila_ are no less clearly allied to Oriental genera. A series of eight peculiar genera belong to the Schizorhinidæ, a family the bulk of which are Australian, while there are only a few African forms. The remaining genera appear to have African affinities, but few of the peculiarly African genera are represented. _Glyciphana_ is characteristic of the Oriental region. The Buprestidæ of Madagascar consist mainly of one large and peculiar genus, _Polybothris_, allied to the almost cosmopolite _Psiloptera_. Most of the other genera are both Ethiopian and Oriental; but _Polycesta_ is mainly South American, and the remarkable and isolated genus _Sponsor_ is confined to the Mauritius with a species in Celebes and New Guinea. The Longicorns are numerous and interesting, there being no less than 24 peculiar genera. Two of the genera of Prionidæ are very isolated, while a third, _Closterus_, belongs to a group which is Malayan and American. Of the Cerambycidæ, _Philematium_ ranges to Africa and the West Indies; _Leptocera_ is only found eastward in Ceylon and the New Hebrides; while _Euporus_ is African. Of the peculiar genera, 2 are of African type; 3 belong to the _Leptura_ group, which are mostly Palæarctic and Oriental, with a few in South Africa; while _Philocalocera_ is allied to a South American genus. Among the Lamiidæ there are several wide-ranging and 7 {284}African genera; but _Coptops_ is Oriental, and the Oriental _Praonetha_ occurs in the Comoro Islands. Among the peculiar genera several have African affinities, but _Tropidema_ belongs to a group which is Oriental and Australian; _Oopsis_ is found also in the Pacific Islands; _Mythergates_, _Sulemus_, and _Coedomæa_, are allied to Malayan and American genera.
