Hob. India, Assam, Burma, Ceylon, ascending up to 7000 ft., 

 perhaps higher ; extending through Eussia and Arabia into Africa, 

 and on the east to the Malayan subregion. 



This species is plentiful where it occurs, but in Burma certainly 

 it is locally distributed. Interesting accounts of its habits are 

 given by Mr. Eothney (Trans. Ent. Soc. Lond. 1889, pp. 347-350) 

 and by Mr. Wroughton (Jour. Bomb. N. H. Soc. vii (1892), 

 p. 30). It is one of the ants noted for tending and keeping 

 " ant-cattle."
