Ceratina, who behaves as the leaf-cutter does, but waits 

 about till her young ones are hatched, and then flies away 

 with them. 



Third, there are mining bees, like Andrena, that make 

 many tunnels in one place, with a distinct tendency to be 

 gregarious, though each digs a distinct hole for itself. 



Fourth, there is the stage represented by Halictus, where 

 several combine to make a burrow or street in the sandy 

 bank, and then dig their respective tunnels opening 

 separately into it. 



Fifth, there is the temporary community represented by 

 Bombus, where only the queens survive the Winter. But it 

 is very interesting to notice, especially in connection with 

 seasonal punctuation, that just as there are some northern 

 humble-bees that have no workers and no community, so 

 there are some southern humble-bees, as in Corsica, which 

 survive as a big family or incipient community through the 

 Winter. 



Sixth, the climax of the series is reached in the 

 permanent society of the hive-bee, where workers as well as 

 queens live through the Winter.
