  This 
  is 
  a 
  common 
  species 
  in 
  the 
  northeastern 
  United 
  States, 
  ranging 
  

   from 
  Illinois 
  eastward 
  ; 
  it 
  is 
  more 
  generally 
  distributed 
  throughout 
  its 
  

   range 
  than 
  are 
  most 
  gomphines. 
  Next 
  to 
  G. 
  exilis 
  it 
  was 
  the 
  com- 
  

   monest 
  Gomphus 
  at 
  Saranac 
  Inn, 
  where 
  it 
  frequented 
  all 
  sorts 
  of 
  waters. 
  

   Imagos 
  were 
  common 
  during 
  the 
  latter 
  part 
  of 
  June 
  and 
  the 
  first 
  two 
  

   weeks 
  of 
  July 
  along 
  the 
  wagon 
  road 
  and 
  railroad 
  between 
  Little 
  Clear 
  

   and 
  Big 
  Clear 
  creeks 
  ; 
  they 
  were 
  foraging 
  there, 
  and, 
  while 
  a 
  little 
  sh^ 
  

   and 
  wary, 
  were 
  not 
  very 
  difficult 
  to 
  catch 
  with 
  a 
  net.
