wider scale. Sncli large and important African genera as 

 roljjhirma and Anthia, are absent; but there are fonr genera 

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

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

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

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

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

 stj/lis has South American affinities ; MicrocMla, Oriental ; the 

 others being related to widely distributed genera. 



The Lucanidte are few in number, and all have African affini- 

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

 peculiar genera. Bnthrorhiva, and three other genera belonging 

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

 scelis and Cliromoptila 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. Ghjci'pliana is characteristic of the Oriental region. 



The Buprestidae of Madagascar consist mainly of one large 

 and peculiar genus, Polyhothris, allied to the almost cosmopolite 

 I'siloptcra. ISIost of the other genera are both Ethiopian and 

 Oriental ; but Polycesfa 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 Prionidas 

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

 which is IMalayan and American. 



Of the Cerambycida^, rhilcmatinm ranges to Africa and the 

 "West Indies ; Leptoccra. 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 Ltptura group, 

 which are mostly l'ala?arctic and Oriental, with a few in 

 South Africa ; while Philocalocera is allied to a South American 

 genus. 



Amoufr the Lamiidre there are several wide-ranging and 7
