  Order 
  DIPTERA 
  

  

  Of 
  this 
  immense 
  group 
  a 
  considerable 
  part 
  is 
  aquatic. 
  That 
  part 
  is 
  

   abundantly 
  represented 
  at 
  Saranac 
  Inn, 
  but 
  did 
  not 
  receive 
  a 
  fair 
  

   measure 
  of 
  attention. 
  Dipterous 
  larvae, 
  comparatively 
  speaking, 
  are 
  

   somewhat 
  better 
  known 
  than 
  are 
  the 
  immature 
  stages 
  of 
  the 
  "lower" 
  

   orders 
  to 
  which 
  we 
  gave 
  our 
  principal 
  attention. 
  Only 
  those 
  Diptera 
  

   which 
  in 
  their 
  immature 
  stages 
  were 
  most 
  accessible, 
  or 
  seemed 
  likely 
  to 
  

   yield 
  new 
  or 
  interesting 
  forms, 
  were 
  studied. 
  Below 
  is 
  an 
  annotated 
  

   list 
  of 
  the 
  groups 
  which 
  came 
  more 
  or 
  less 
  under 
  observation. 
  

  

  Tipjilidae 
  — 
  Crane 
  flies. 
  Abundant 
  in 
  individuals, 
  representing 
  a 
  con- 
  

   siderable 
  number 
  of 
  species. 
  No 
  attempt 
  was 
  made 
  to 
  determine 
  

   the 
  few 
  specimens 
  collected, 
  save 
  the 
  giant 
  Tipula 
  abdominalis 
  

   Say, 
  whose 
  larva 
  is 
  described 
  below. 
  A 
  small 
  species 
  with 
  beautifully 
  

   spotted 
  wings 
  was 
  bred 
  from 
  a 
  floating 
  pupa, 
  but 
  the 
  single, 
  imperfect, 
  

   alcoholic 
  specimen 
  is 
  insuflicient 
  for 
  description.

  the
