  This 
  l)rightest 
  of 
  our 
  green 
  Tijplilnctjhas 
  was 
  

   found 
  iu 
  large 
  numbers 
  at 
  Denver 
  and 
  Clear 
  Creek 
  

   Canyon, 
  upon 
  the 
  leaves 
  of 
  willows 
  August 
  7 
  to 
  18. 
  

  

  This 
  s])ecies 
  is 
  close 
  to 
  ohtusa 
  but 
  is 
  more 
  robust, 
  the 
  vertex 
  is 
  uot 
  

   produced, 
  but 
  evenly 
  rounded, 
  and 
  the 
  last 
  ventral 
  segmeut 
  of 
  the 
  

   female 
  is 
  sinuate 
  at 
  the 
  sides 
  posteriorly. 
  

  

  I 
  have 
  found 
  this 
  species 
  quite 
  abundant 
  ou 
  willows 
  near 
  Fort 
  Col- 
  

   lins, 
  at 
  Palmer 
  Lake, 
  and 
  on 
  Marshall 
  Pass, 
  Colorado. 
  Those 
  from 
  the 
  

   last-nan)cd 
  i)lace 
  were 
  taken 
  August 
  23, 
  and 
  are 
  more 
  or 
  less 
  smoky 
  in 
  

   color, 
  some 
  being 
  nearly 
  black
