wider scale. Such large and important African genera as 

 Polyhirma and Anthia, are absent ; but there are four genera 

 in common with South Africa, and two with West Africa ; while 

 three others are as much Oriental as African. One genus, 

 Disirigus, is wholly Oriental ; and another, Homalosoma, Aus- 

 tralian. Colpodes, well developed in Bourbon and Mauritius, is 

 Oriental and South American. Of the peculiar genera, Sphccro- 

 stylis has South American affinities ; Microchila, Oriental ; the 

 others being related to widely distributed genera. 



The Lucanidse are few in number, and all haye African affini- 

 ties. Madagascar is very rich in Cetoniidce, and possesses 20 

 peculiar genera. Bothrorhina, and three other genera belonging 

 to the Ichnostoma group, have wholly African relations. Dory- 

 scelis and Chromoptila are no less clearly allied to Oriental 

 genera. A series of eight peculiar genera belong to the Schizo- 

 rhinidse, 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 Buprestidse 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 Prionidse 

 are very isolated, while a third, Closterus, belongs to a group 

 which is Malayan and American. 



Of the Cerambycidee, 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 Palaearctic and Oriental, with a few in 

 South Africa ; while Philocalocera is allied to a South American 

 genus. 



Among the Lamiidae there are several wide-ranging and 7
