 whilst in their habit of living in societies, they resemble a large

 tribes of which these communities consist. A more particular 

 account of their operations will be given in a later part of this 

 volume ; and at present it will be sufficient to say, that the larva? 

 resemble the perfect insect, except in the absence of wings, and are 

 the workers. Among the adult insects there are 

 some, which never acquire wings, and in which 

 the reproductive organs are not developed ; these,

 the larvae, and the mandibles are very long and 

 cross each other ; they are far less numerous 

 than the larvae, and live near the outer surface 

 of the nest, so that they are the first to make their appearance
