in origin, iind nut cuused by a geograijbical barrier having existed at au earlier 

 epocli. Where the physiography of West Africa is similar to that of the 

 Eastern districts, a similar fauna appears — as, for instance, iu 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 turn up. The genera 

 I'ohiptychus and Tcmnora have very many species iu West Africa and few iu 

 East Africa ; but allowance must he made for the fauna of East Africa being 

 less explored than that of the West Coast. The South of the Continent, from 

 Capetown to Benguella and the Zambesi, is physiographically and faunistically 

 similar to that of East Africa. Tiiere are, however, some si)ecies of Lepidoptera 

 which do not go far northwards into the tropics. Of Hawk Moths, Theretni 

 capensis, Poli/pfi/chus mututa, and Oliijotjruplm juniperi may be spoken of as 

 being characteristic of this area. Some other species {RhodaJ'ra opheltes and 

 mnrshalli, Temnova iiatalis and nainaipia, Microsplunx puniilio, Leptoclanis 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 Subregion has 4 genera of its own (Fauogena, Lomoci/ma, 

 Temnoripais, Mucmseiiia) and 20 species* and G subspecies restricted to itself, 

 out of ~3 genera and 44 species. We append a list of the species found in the 

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