tated and stored in the ingluvies, or crop by a certain number of 

 workers. From the fact that other Myrmicine ants, although they 

 spin no cocoons, often have well-developed salivary glands, we may 

 infer that these organs have much the same function as in Pccdalgns. 

 To prove this, however, additional observations are necessary, 

 though other reasons for believing it to be the case, will appear in 

 the sequel. In all the larval stages of the Dolichoderinas and in the 

 immature larvae of Camponotinse the salivary glands are probably 

 put to a similar use. In the species of (Ecophylla and Polyrhachis 

 that employ their young larvae for spinning the silken portions of
