  That 
  these 
  last, 
  whatever 
  they 
  may 
  have 
  been, 
  were 
  extraneous, 
  is 
  evident 
  

   from 
  an 
  examination 
  of 
  the 
  maxillae 
  of 
  fresh 
  or 
  alcoholic 
  specimens 
  (tig, 
  34). 
  

   McLachlan 
  had 
  for 
  examination 
  only 
  a 
  few 
  dried 
  specimens. 
  "Larva 
  probably 
  

   aquatic". 
  

  

  The 
  single 
  species 
  of 
  this 
  genus 
  hitherto 
  known, 
  C. 
  areolaris 
  Hagen 
  

   has 
  been 
  reported 
  only 
  from 
  the 
  southern 
  states. 
  There 
  are 
  numerous 
  

   specimens 
  of 
  it, 
  however, 
  in 
  the 
  Museum 
  of 
  comparative 
  zoology 
  from 
  

   Waltham 
  and 
  Cambridge 
  Mass., 
  as 
  well 
  as 
  a 
  number 
  from 
  Florida. 
  The 
  

   species 
  found 
  at 
  Saranac 
  Inn 
  and 
  described 
  below 
  differs 
  from 
  areolaris 
  

   in 
  being 
  of 
  darker 
  color 
  on 
  the 
  wings 
  (black, 
  where 
  areolaris 
  is 
  but 
  

   brown), 
  of 
  larger 
  size 
  (females 
  of 
  areolaris 
  do 
  not 
  exceed 
  the 
  measure- 
  

   ments 
  given 
  by 
  Hagen^ 
  ), 
  and 
  in 
  having 
  the 
  vein 
  Cuj 
  seven-branched 
  (it 
  

   is 
  six-branched 
  in 
  areola 
  ris).
