  July 
  numerous 
  pupal 
  cases 
  of 
  an 
  unknown 
  species 
  were 
  seen 
  sticking 
  out 
  

   between 
  the 
  boards 
  which 
  covered 
  the 
  bank 
  of 
  the 
  creek 
  beside 
  the 
  

   hatchery. 
  Many 
  larvae 
  and 
  pupae 
  of 
  the 
  singular 
  Bittacomorpha

  were 
  collected 
  from 
  the 
  rotting 
  vegetation 
  in 
  little 
  shallow 
  

   bays 
  in 
  the 
  borders 
  of 
  Little 
  Clear 
  creek, 
  where 
  they 
  were 
  very 
  

   abundant; 
  the 
  imagos 
  were 
  seen 
  commonly, 
  also, 
  gliding 
  slowly 
  along 
  

   through 
  the 
  air 
  with 
  a 
  singularly 
  phantom-like 
  appearance 
  and 
  motion. 
  

   The 
  few 
  that 
  retained 
  their 
  six 
  caducous 
  legs 
  after 
  pinning 
  are 
  in 
  the 
  

   state 
  collection 
  at 
  Albany. 
  

  

  Chironomidae 
  and 
  Culicidae 
  — 
  gnats, 
  mosquitos, 
  midges, 
  etc. 
  These 
  

   famiUes 
  were 
  abundantly 
  represented, 
  and 
  a 
  goodly 
  number 
  of 
  species 
  

   were 
  reared, 
  but, 
  unfortunately, 
  there 
  has 
  not 
  been 
  opportunity 
  for 
  the 
  

   preparation 
  of 
  descriptions 
  in 
  time 
  for 
  incorporation 
  into 
  this 
  report. 
  

  

  Mycetophilidae. 
  During 
  the 
  last 
  days 
  of 
  our 
  session 
  the 
  large 
  A

   dulum 
  montanum 
  Roeder 
  was 
  common 
  in 
  the 
  hatchery 
  windows. 
  

  

  Simuliidae. 
  The 
  single, 
  unobtrusive 
  species, 
  S. 
  venustum 
  Say, 
  

   was 
  very 
  common; 
  during 
  the 
  earlier 
  part 
  of 
  our 
  session 
  the 
  hatchery 
  

   windows, 
  specially 
  the 
  windows 
  nearest 
  the 
  inflow 
  pipes, 
  swarmed 
  

   with 
  them. 
  Some 
  new 
  observations 
  on 
  the 
  oecology 
  and 
  habits 
  of 
  the 
  

   black 
  fly 
  in 
  its 
  earlier 
  stages 
  are 
  recorded 
  on 
  pages 
  407-8 
  and 
  illustrated 
  

   in

  Stratiomyiidae. 
  Soldier 
  flies. 
  But 
  few 
  specimens 
  were 
  taken 
  belong- 
  

   ing 
  to 
  this 
  family. 
  These 
  belonged 
  to 
  two 
  very 
  interesting 
  species, 
  

   one 
  to 
  our 
  largest 
  and 
  handsomest, 
  Stratiomyia 
  badius 
  Walk., 
  

   whose 
  larva 
  is 
  described 
  on 
  page 
  576 
  ; 
  and 
  the 
  other, 
  one 
  of 
  the 
  smallest 
  

   members 
  of 
  the 
  family, 
  representing 
  a 
  new 
  genus 
  and 
  species, 
  is 
  described 
  

   below 
  by 
  D. 
  W. 
  Coquillett, 
  and 
  named 
  by 
  him 
  Zabrachia 
  polita. 
  

  

  Empididae. 
  A 
  new 
  genus 
  and 
  species 
  was 
  found 
  in 
  its 
  immature 
  

   stages 
  associated 
  with 
  Simulium 
  in 
  rapids 
  and 
  reared: 
  it 
  is 
  de- 
  

   scribed 
  below 
  by 
  Mr 
  Coquillett 
  as 
  Roederiodes 
  juncta. 
  

   Hilara 
  mutabilis 
  Loew 
  was 
  common 
  about 
  the 
  shores 
  of 
  Lake 
  

   Clear 
  during 
  the 
  last 
  week 
  in 
  June. 
  Little 
  companies 
  would 
  start 
  before 
  

   one's 
  feet 
  when 
  approaching 
  the 
  edge 
  of 
  the 
  water, 
  disperse 
  and 
  settle 
  

   again 
  near 
  by. 
  

  

  Sciomyzidae. 
  Two 
  interesting 
  swale 
  flies, 
  Sepedon 
  fuscipen- 
  

   nis 
  Loew 
  and 
  Tetanocera 
  pictipes 
  Loew, 
  were 
  reared' 
  in 
  

   large 
  numbers. 
  Their 
  larvae 
  and 
  pupae 
  are 
  figured 
  and 
  described 
  here- 
  

   with. 
  These 
  were 
  from 
  below 
  the 
  hatchery 
  on 
  Little 
  Clear 
  creek. 
  Above 
  

   the 
  hatchery, 
  nearer 
  the 
  railroad 
  in 
  the 
  natural 
  meadow 
  beside 
  the 
  water, 
  

   were 
  collected, 
  while 
  sweeping, 
  several 
  additional 
  species 
  of
