This is the notorious and vicious " Red Ant " of India ; it in- 

 habits trees and makes a nest of leaves. Its habits have been very 

 fully described by Messrs. Aitken *, Wroughton t, Kothnt^y J, 

 and Green §. Mv. E. E. Green records the remarkable habit 

 (E. smarai/diiia has of using its larva) to spin the silk with which 

 its nest of leaves is constructed. In Ivanara -ind some other parts 

 of India, and throughout Jku'ma and Siam, a paste made of this 

 species of ant poimded is eaten as a condiment with curry.
