CONCLUDING REMARKS. 



It was my intention to have entered at length into the 

 highly interesting question of the geographical distribution 

 of the butterflies described in this work, both over Southern 

 Africa and throughout the globe, but I have found the data 

 that I have hitherto been able to collect, especially as regards 

 the range of species over the African Continent, too scanty 

 to admit of a proper discussion of the subject. The field is 

 immense, and observers are very few and widely separated ; 

 but materials are surely though gradually accumulating, and 

 there is every reason to hope that, in a few years' time, the 

 facts at our disposal will render practicable a fairly accurate 

 generalization. 



The following Table must accordingly be regarded as a 

 summary only of my present knowledge of the geograjihical 

 range of the South African Rhopalocera already known. 

 New species, as vvell as new localities (often most unexpected) 

 of known forms, are constantly being discovered ; and the 

 importance of this ever-accumulating evidence, inappreciable 

 as it may be at any given time, should never be lost sight of 

 by those -who endeavour to deduce from already-recorded 

 facts the indications of general laws.
