in orio-in, luul not auised by a geographical barrier liaviiig existed at au earlier 

 epoch. ^Vllere the physiogvaiihy of West Africa is similar to that of the 

 Eastern districts, a similar fauna appears — as, for instance, in Angola and the 

 Hinterland of Sierra Leone and of the Gold Coast ; and where in East Africa there 

 are extensive forests, insects of the West African type tnrn up. The genera 

 l'ol>ij>t;/rhiis and TcmiHira have very manj- species in AVest Africa and few in 

 East Africa : Imt allowance must be made for the fauna of East Africa being 

 less e.\j)]ored than that of the West t'oast. The South of the Continent, from 

 ('aj^ctowu (o Bciiguella and the Zambesi, is i)hysiographically and faunistically 

 similar to that of I<]ast Africa. Tliere are, however, some sjiecies of Lepidoptera 

 wliicli do not go far northwards into the tropics. Of Hawk Moths, Tlicretra 

 rapeiwi<, l'oli/})h/clius iniitata, and OUijograplia jiiniperi may be spoken of as 

 being characteristic of this area. Some other species {Rhudafra opheltes and 

 nutrslialU, Temnora ixital/s a,nd namuqua, Microsphinx pumilio,Leptoclani8 pulchra, 

 etc.) are too rare to be safely regarded as being restricted to the South. 



The differences between Madagascar and the Continent are very obvious. 

 The Malagassic Suhregion has 4 genera of its own {^Panogena, Lomocijma, 

 Temnoripais, Muasseiiia) and 20 species * and subspecies restricted to itself, 

 out of 23 genera and 44 species. We append a list of the species found in the 

 Subregion, those confined to it being marked with au asterisk : —
