 her, than if we had been trees blown about by the 

 wind. 



Some of the wasps dig deep into the stems of bushes 

 to form galleries for their nests, but we found one wise 

 genus that went in only far enough to make one or two 

 cells, thus saving the trouble of carrying her cuttings 

 thirty or forty centimeters in direct opposition to the 

 force of gravity. This was Odynerus, whose nests we 

 found in July, in blackberry and raspberry 

 stems. Our first species was perennis, whose 

 nests bear her mark in the shape of a pellet 

 of earth placed above each mud partition. 

 One of her cells contained a wasp larva and
