274 A STR1DULATING ORGAN IN A SOUTH AFRICAN ANT. 



was sent to me by the Rev J. R. Ward, of Richmond, Natal, to 

 whom I am indebted for many objects of microscopic interest 

 which have furnished material for previous communications to 

 the Club, but the species seems to be rather widely distributed 

 in South Africa, and the very perfect example which I have 

 also brought for exhibition was captured by my daughter at 

 Uitenhage, in Cape Colony, about four months ago. It has 

 been identified as Streblognathus JEthiopicus.
