OUR ANTS. 197 



Major Yerbury describes nests of this species: "Nest in bush, 

 *' pear-shaped, roughly 5" long, 3* diameter, made of a substance resem- 

 " bling bleached, decomposed cowdung. Another nest, material blacker 

 *' and more like papier mache, possibly due to age ; inverted bottle- 

 " shape, apical portion almost cylindrical. Nests very common."

This is the common forest species of Western India. It builds 

 large nests of ' brown paper,' with projecting pent-houses, more or
