 ([ueen were tirst deteiinined whenever possible, and that of the 

 worker coinpared with it. 



Repeated observations on some of the ants most common in tlie 

 vicinity of Austin, viz. the Poncriuac, nests of which are frequently 

 found cüiitaining eggs. larvae, pupae, workers and sonietimes males,

 in these forms.
