  But 
  little 
  collecting 
  was 
  done 
  in 
  such 
  

   net-clogging 
  situations, 
  and 
  hence, 
  but 
  a 
  few 
  of 
  the 
  nymphs 
  were 
  

   obtained. 
  A 
  single 
  cast 
  skin 
  was 
  found 
  on 
  a 
  stump 
  in 
  the 
  edge 
  of 
  a 
  

   boggy 
  place 
  in 
  Little 
  Clear 
  outlet, 
  about 
  eight 
  inches

  the

  along 
  its 
  fore 
  

   margin; 
  mental

  10

  sixth 
  (counting 
  from 
  

   the 
  side) 
  longest; 
  lateral 
  setae 
  seven 
  or 
  six,

  seven 
  the 
  basal 
  one 
  

   smaller 
  than 
  the 
  others 
  ; 
  movable 
  hook 
  hardly 
  longer 
  than 
  the

   much 
  stouter; 
  lateral 
  lobe 
  with 
  about 
  seven 
  low

  two 
  or 
  three 
  graduated 
  spinules.

  a 
  prominent 
  lateral 
  process 
  at 
  each 
  side 
  of 
  the

  a 
  similar 
  anteriorly

  SOMATOCHLORA 
  

  

  This 
  genus 
  is 
  by 
  far 
  the 
  largest 
  in 
  our 
  corduline 
  fauna. 
  I. 
  have 
  set 
  

   apart 
  three 
  species 
  hitherto 
  placed 
  in 
  it, 
  and, 
  with 
  these 
  aside, 
  it 
  still 
  

   comprises 
  about 
  half 
  of 
  the 
  subfamily. 
  The 
  species 
  seem 
  to 
  be 
  common 
  

   only 
  in 
  high 
  altitudes 
  in 
  the 
  northern 
  part 
  of 
  the 
  United 
  States, 
  and 
  in 
  

   British 
  America. 
  In 
  all 
  my 
  collecting 
  I 
  have 
  observed 
  but 
  one 
  species 
  

   in 
  flight. 
  This 
  species 
  was 
  S. 
  elongata, 
  of 
  which 
  a 
  few 
  specimens 
  

   were 
  seen 
  flying 
  about 
  the 
  borders 
  of 
  Bone 
  pond 
  on 
  Aug. 
  14. 
  I 
  obtained 
  

   one 
  nymph 
  only 
  of 
  the 
  species. 
  That 
  one 
  was 
  from 
  Little 
  Clear 
  pond. 
  

   From 
  it 
  I 
  bred 
  a 
  fine 
  male 
  imago 
  July 
  5. 
  This 
  seems 
  to 
  be 
  the 
  only 
  

   specimen 
  bred 
  for 
  all 
  of 
  our 
  species; 
  and 
  so 
  diverse 
  are 
  the 
  imagos 
  among 
  

   themselves 
  that 
  the 
  nymphs 
  may 
  hardly 
  be 
  expected 
  to 
  conform 
  closely 
  

   to 
  the 
  characters 
  of 
  this 
  one 
  in 
  details. 
  I 
  give 
  herewith 
  figures 
  of 
  the
