B. SUB-FAMILY DORYLIDE3. 

 (Wandering, Driver or Visiting Ants.) 



These ants are nomads, having no fixed place of 

 abode, never resting more than several days in one 

 place. There are two groups (a) the Dorylus 

 Group, found in Africa and some species in Asia 

 also; (b) the Eciton Group, which is found in 

 America only. The males, females and workers 

 differ remarkably. The female is usually very 

 large and is blind: the workers are blind, like the 

 female, or with rudimentary simple eyes. There 

 are sometimes two worker castes, the soldier type, 

 large and with strong, long mandibles; the smaller 

 worker, whose mandibles are suitable for industrial 

 purposes. 



The Dorylus Group is represented by genera 

 Dorylus, /Uionuna. and Aoiictiis. Savage describes 

 in a very interesting manner the habits of Driver 

 Ants in Africa. They march in huge columns, and 

 v/ill pass through houses, ridding them of vermin, 

 meat, etc., for they are carnivorous types. Savage 

 says that if confined they will attack animals sucli 

 as large lizards, snakes, and even monkeys and pigs. 



Belt thus describes the habits of one of the Eci- 

 tons (the American type): "One of the smaller 

 species (Eciton pracdator) used occasionally to visit
