  Igarape 
  Assti 
  is 
  about 
  120 
  miles 
  from 
  the 
  city 
  of 
  Pard. 
  It 
  is 
  situated 
  about 
  1,000 
  

   feet 
  above 
  the 
  sea 
  level 
  and 
  in 
  the 
  heart 
  of 
  the 
  forest. 
  I 
  arrived 
  at 
  my 
  destination 
  

   about 
  the 
  first 
  of 
  December, 
  1911, 
  which 
  is 
  the 
  latter 
  part 
  of 
  the 
  dry 
  season. 
  Thte 
  rains 
  

   did 
  not 
  start 
  until 
  about 
  the 
  middle 
  of 
  January, 
  and 
  from 
  then 
  on 
  it 
  rained 
  almost 
  

   every 
  day 
  for 
  three 
  or 
  four 
  hours. 
  It 
  was 
  usually 
  fine 
  in 
  the 
  morning, 
  but 
  toward 
  12 
  

   o'clock 
  clouds 
  loomed 
  up 
  on 
  the 
  horizon. 
  When 
  these 
  wet 
  days 
  come 
  it 
  is 
  very 
  hard 
  

   to 
  keep 
  things 
  from 
  molding, 
  especially 
  insects. 
  There 
  were 
  very 
  few 
  Tipulidse 
  to 
  

   be 
  had 
  during 
  the 
  dry 
  season, 
  but 
  they 
  became 
  more 
  plentiful 
  as 
  the 
  wet 
  season 
  

   advanced. 
  I 
  used 
  to 
  go 
  out 
  with 
  a 
  waterproof 
  on 
  and 
  an 
  umbrella 
  in 
  one 
  hand 
  and 
  

   net 
  in 
  the 
  other. 
  The 
  place 
  where 
  I 
  stopped 
  was 
  right 
  beside 
  a 
  swamp, 
  so 
  that 
  it 
  made 
  

   it 
  all 
  the 
  better 
  for 
  your 
  material. 
  At 
  night 
  I 
  put 
  a 
  light, 
  mounted 
  on 
  a 
  chair, 
  with 
  a 
  

   sheet 
  behind 
  it, 
  and 
  this 
  had 
  the 
  desired 
  effect.' 
  

  

  It 
  is 
  not 
  proposed 
  nor 
  mtehded 
  to 
  give 
  the 
  characters 
  of 
  any 
  

   genus, 
  except 
  where 
  such 
  genera 
  have 
  been 
  insulTiciently 
  described. 
  

   In 
  the 
  case 
  of 
  monotypic 
  genera, 
  described 
  in 
  papers 
  that 
  are 
  diffi- 
  

   cult 
  of 
  access 
  to 
  the 
  student, 
  the 
  generic 
  and 
  specific 
  descriptions 
  

   are 
  included. 
  Under 
  each 
  genus 
  is 
  given 
  references 
  to 
  the 
  best 
  

   characterizations 
  of 
  the 
  genera 
  that 
  are 
  available, 
  some 
  one 
  or 
  more 
  

   of 
  which 
  will 
  be 
  accessible 
  to 
  the 
  general 
  student 
  of 
  the 
  Diptera. 
  

   As 
  regards 
  the 
  synonomy 
  of 
  the 
  species, 
  it 
  has 
  been 
  given 
  complete 
  

   in 
  the 
  case 
  of 
  purely 
  Neotropical 
  forms. 
  In 
  wide-ranging 
  or 
  cos- 
  

   mopolitan 
  species, 
  only 
  the 
  more 
  important 
  or 
  significant 
  changes 
  

   are 
  given. 
  

  

  For 
  the 
  information 
  of 
  the 
  reader 
  concerning 
  any 
  points 
  of 
  nomen- 
  

   clature 
  that 
  may 
  be 
  doubtful,

  give
