330 CONCLUDING REMARKS. 



Widening the range so as to include, as far as known, 

 Africa South of the Equator, the amount of peculiarity is 

 increased by the addition of 41 species, making the whole 

 number of endemic forms in the larger region 136, or about 

 three- fifths of th^ South African species ; while, if the whole 

 of the African Continent is made the limit, a further addi- 

 tion of 59 species must be made, yielding a total of 195 (or 

 all but nine-tenths of the entire number of Butterflies that 

 have hitherto been found in Extra-Tropical South Africa) 

 which are confined in their range to Africa, alone. 



This result speaks strongly for the dominant character of 

 African fcrms, and the similarity of the conditions of life, 

 throughout the continent, and tends to show how small has 

 been the influx of immigrant species powerful enough suc- 

 cessfully to contest the soil with the indigenes. All but one 

 of the small proportion of South African species that are 

 found in other continents are natives of Asia, the exception 

 (if actually such) being a native of Europe. Seven only are 

 European natives, three have been found in America, and 

 but tw r o have occurred in the Australian Continent. 



It now only remains for me to express my grateful thanks 

 for the very kind and valuable assistance so freely accorded 

 me, in many instances by those to whom I am personally 

 unknown. 



Nearly all the kind assistants of my labours named in the 

 Preface to this volume have laid me under fresh obligations 

 by renewed and continuous aid. Among these I have plea- 

 sure in specially mentioning Mr. C. J. Andersson, Mr. W. 

 S. M. D'Urban, the Yen. H. Kitton (now Archdeacon of 

 King William's Town), Mr. E. L. Layard, and Mr. L. Taats, 

 all of whom have most liberally contributed to my stores of 

 specimens and information, 



But not to these friends only am I now indebted. Since 

 the publication of trie First Part of this work, I have been 

 so fortunate as to find many other persons, chiefly residents 

 in South Africa, not only willing but anxious to render every 

 aid in their power to Entomology, and the majority of these 

 I rejoice to number among my correspondents. How greatly 

 the completeness of the Catalogue has been promoted by 

 their means, or how encouraged in my work I have been by 

 such cordial co-operation, it is needless to relate. Every
