  This 
  species, 
  hitherto 
  known 
  from 
  three 
  somewhat 
  immature 
  specimens 
  

   in 
  the 
  Museum 
  of 
  comparative 
  zoology, 
  was 
  common 
  at 
  Saranac 
  Inn. 
  

   Many 
  imagos 
  of 
  both 
  sexes 
  were 
  observed 
  flying 
  over 
  Little 
  Clear 
  creek 
  

   in 
  the 
  places 
  where 
  the 
  shallow 
  current 
  rippled 
  over 
  sand. 
  The 
  males 
  

   would 
  fly 
  back 
  and 
  forth 
  a 
  few 
  times 
  and 
  then 
  rest 
  for 
  a 
  time 
  on 
  some 
  

   prominent 
  twig 
  near 
  shore, 
  generally 
  on 
  the 
  higher 
  bank. 
  They 
  were 
  not 
  

   difficult 
  to 
  approach 
  or 
  to 
  capture 
  when 
  at 
  rest. 
  Except 
  when 
  oviposit-
