breed in ant-nests. The larva of E. inda is recorded from nests of 

 Formica integra and the adult from those of F. rufa obscuripes. Dur- 

 ing the spring of 1906, while watching a large nest of F. exsectoides, 

 I saw a E. inda fly from a distance, alight on the mound and at once 

 bury itself out of sight in the earth and vegetable debris. E. Jiirtipes 

 has also been taken in the nests of F. obscuripes by Bruner. It ap- 

 pears, therefore, that all the myrmecophilous Cetoniinse have a predi- 

 lection for ants of the genus Formica or of the allied genus Plagio- 

 lepis, which represents Formica in South Africa. That this predilec- 

 tion is exhibited by so many genera of the subfamily and in such 

 widely separated regions as South Africa, Europe and North America, 

 shows that it must be of very ancient origin.
