  CRABRONIDiE. 
  

  

  Rather 
  small 
  diggers, 
  with 
  an 
  unusually 
  large 
  quadrate 
  head. 
  They 
  are 
  

   not 
  uniform 
  in 
  habit, 
  but 
  many 
  live 
  in 
  pithy 
  stems, 
  burrow 
  in 
  dead 
  wood 
  

   or 
  make 
  use 
  of 
  an 
  old 
  cavity. 
  They 
  store 
  their 
  cells 
  with 
  flies, 
  plant-lice, 
  

   other 
  insects 
  or 
  even 
  spiders.
