1900. J Cataloyue of the Coleoptcva of South Africa. 21 



C. J. Aiidersson, Alex. Eoss, Eev. F. Kolbe, Eev. J. A. O'Neil, I ani 

 especially indebted for invaluable information, as well as for tlie 

 accumulation of material. But there are many othei- correspondents 

 who have also helped, and to those I tender my very best thanks, 

 and may this Catalogue, in which I have endeavoured to brin<i; 

 together within certain limits all that is known of the South African 

 representatives of the Family Scaeab.eid.t;, be to them the tangible 

 expression of my indebtedness. 



The types and co-types of nearly all the new genera or species are 

 in the South African Mus^eum.
