 around for a few minutes, and when she did this all 

 her feet came down to the ground, the beetle being 

 allowed to hang loosely. At last she made the best of a

 occupied with hunting, the capture of each beetle taking

 home she spent fifteen or twenty minutes in the nest. 



This species soon became very common, and for two 

 weeks scarcely a morning passed without our finding at

 found, one morning, two nests within six inches of each 

 other. It turned out afterward that these were inhabited 

 by two different wasps ; but at the moment we supposed 

 that one of them had been dug and deserted and then a
