  Of 
  the 
  interesting 
  but 
  rather 
  limited 
  family 
  of 
  the 
  North 
  American 
  

   Uroceridae, 
  in 
  which 
  six 
  genera 
  are 
  included, 
  about 
  one 
  half 
  of 
  the 
  

   species 
  are 
  embraced 
  in 
  the 
  genus 
  Urocerus. 
  This 
  genus 
  is 
  one 
  that 
  

   evidently 
  finds 
  its 
  most 
  favorable 
  conditions 
  in 
  the 
  Canadian 
  provinces,

  Cresson 
  List
