wider scale. Such large and important African genera as 
Polyhirma and Antlvia , 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, 
Dislrigus , 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- 
sti/lis has South American affinities ; Microchila, Oriental ; the 
others being related to widely distributed genera. 
The Lucanidse are few in number, and all have African affini- 
ties. Madagascar is very rich in Cetoniidce, and possesses 20 
peculiar genera. Bothrorhina , and three other genera belonging 
to the Iclmostoma group, have wholly African relations. Dory- 
sedis and Chromoptila are no less clearly allied to Oriental 
genera. A series of eight peculiar genera belong to the Schizo- 
rhinidie, 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 Buprestkke 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 Brionidm 
are very isolated, while a third, Closterus, belongs to a group 
which is Malayan and American. 
Of the Cerambycidie, Philematium ranges to Africa and the 
West Indies ; Leptoc&ra 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 Palasarctic 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
