Gen. 36, Tetramorium (Mayr).

 spurs simple.

Kanara E. H. Aitken. 



Calcutta G, A. J. Rothney (variety). 



I have several times seen T. obesum harvesting some vegetable 

 product (not grain) which looked like dead wood, or fungus. 

 Dr. Forel records of a Tunisian species, that he found them, as 

 slaves, in the nests of other ants; though I have never been able to 

 detect anything approaching to slavery among the Indian ants, I 

 should not have been astonished to find Tetramorium enslaved, for 

 her movements and manner remind one irresistibly of the patient, 

 plodding ass. 



138. Tetr. similUmum (Nyl.). 

 Poona Districts. 



In the only nest I have found there was a little grain stored. 

 The general economy seemed to me to be very much that of Hole, 

 clarus, a nest of which was close by. 



339. Tetr. coespitum (Lin.). 

 Poona Districts. 



This insect is almost, if not quite, identical with the European form.
