Amazon Ants should always select the pupae which will after- 

 wards be developed into neuters, and never take those from 

 which males or females will issue. 



The Amazon of the Continent is not the only Ant which 

 enslaves the ueutei-s of another species, for in different parts of 

 the world several species of Ants have been observed which 

 seize upon workers belonging to other nests, and bring them 

 to do the work of the home. A ErazUian species {Myrmica 

 paleata) has been observed to act in a similar manner. 



In the accompanying illustration are shown two remarkable 

 nests, made by insects of the same genus, which have been 

 placed side by side in order to show the different manner in 

 which cells are arranged by insects which are closely allied to 

 each other.

The smaller, though more conspicuous nest, is formed by an 

 insect which is called Polistes aterrima, a name which is very 

 appropriate to the creature, inasmuch as the generic title sig- 

 nifies a builder, or the founder of a city, and the specific name 

 signifies intense blackness, and is given to the insect on account
