The peculiar or characteristic forms are Amauris(Danaidse); Gnophodes, Leptoneura, Bicyclus, Heteropsis andCcenyra (Satyridse) ; Acrcea (Acraeidae) ; LacJmoptcra, Precis,Salamis, Crenis, Godartia, Amphidcma, Pscudacrcea, Catuna,Euryphcnc, Romalceosoma, Hamanumida, Aterica, Harma,Mencris, Charaxes, and Philognoma (Nymphalidae) ; Pentila,Liptena, Durbania, Zcritis, Capys, Phytala, Epitola, Heivitsoniaand Deloneura (Lycamidffi) ;Pscudopontia, Idmais, Tcracolus,Callosune (Pieridse) ; Abantis, Ceratrichia and Caprona (Hesperidse).The total number of species known is about 750which is very poor for an extensive tropical region, but thisis not to be wondered at when the nature of much of thecountry is considered. It is also, no doubt, partly due to ourcomparative ignorance of the great equatorial forest district,which is the only part likely to be very productive in thisorder of insects.Coleoptcra.— In our first representative family, Cicindelidseor tiger-beetles, the Ethiopian region is rather rich, having 13genera, 11 of which are peculiar to it; and among these aresuch remarkable forms as Manticora, Myrmecoptcra and Dromicawith Mcgacephala, a genus only found elsewhere in Australiaand South America.In Carabidae or carnivorous ground beetles, there areabout 75 peculiar genera. Among the most characteristicare Anthia, Polyrhina, Graphipierus and Piczia, which arealmost all peculiar ; while Orthogonius, Hexagonia, Macrochilus,Thyreopterus, Eudcma, and Abacctus are common to this andthe Oriental region ;and Hypolithus to the Neotropical.Out of 27 genera of Buprestidse, or metallic beetles, only 6 arepeculiar to the region, one of the most remarkable being Polybothrus,confined to Madagascar.Sternocera and Chrysochroa arecharacteristic of this region and the Oriental ; it has Julodis incommon with the Mediterranean sub-region, and Bclionotawith the Malayan.The region is not rich in Lucanidae, or stag-beetles, possessingonly 10 genera, 7 of which are peculiar, but most of them con-
