  This 
  contains 
  the 
  true 
  bees, 
  most 
  of 
  them 
  social, 
  with 
  workers 
  or 
  un- 
  

   developed 
  females 
  in 
  the 
  colonies, 
  and 
  most 
  of 
  them 
  storing 
  honey 
  to 
  a 
  

   greater 
  or 
  less 
  extent.

  The 
  species 
  of 
  this 
  genus 
  resemble 
  the 
  bumble 
  bees, 
  but 
  are 
  really 
  para- 
  

   sitic, 
  in 
  so 
  far 
  as 
  they 
  develop 
  as 
  unbidden 
  guests 
  in 
  the 
  nests 
  of 
  the 
  

   Bombi. 
  The 
  females 
  have 
  no 
  pollen-baskets; 
  the 
  males 
  are 
  not 
  easily 
  

   distinguished 
  from 
  bumble 
  bees.
