  GonomyisB 
  appear 
  to 
  be 
  numerous 
  in 
  the 
  Neotropical 
  regions 
  and 
  

   many 
  species 
  are 
  herein 
  recorded. 
  Some 
  of 
  the 
  aberrant 
  species 
  

   that 
  I 
  have 
  referred 
  to 
  the 
  subgenus 
  Leiponeura 
  Skuse, 
  have 
  been 
  

   placed 
  in 
  various 
  genera 
  of 
  the 
  Antochini, 
  simply 
  because 
  of 
  the 
  lack 
  

   of 
  one 
  branch 
  of 
  the 
  radial 
  sector.

   Johnson, 
  and 
  the 
  two 
  Australian 
  species 
  of 
  Leiponeura 
  are, 
  apparently, 
  

   all 
  Gonomyise. 
  I 
  have 
  had 
  for 
  examination 
  all 
  of 
  the 
  American 
  

   Gonomyi£e 
  excepting 
  G. 
  galactoptera 
  Bergroth, 
  of 
  Alaska. 
  (Aldrich 
  

   gives 
  also 
  G. 
  caudata 
  Lundberg, 
  but 
  Kertesz 
  calls 
  this 
  an 
  Empeda.) 
  

  

  The 
  American 
  species 
  referable 
  to 
  the 
  subgenus 
  Gonomyia 
  Meigen, 
  

   (type

   new

  Those 
  species 
  referable 
  to 
  Leiponeura 
  Skuse 
  (type

  In

  prominent

  the 
  sides 
  of 
  the 
  

   mesothoracic 
  prsescutum 
  that 
  I 
  have 
  called 
  the 
  ''pseudosuture" 
  are 
  

   normal 
  in 
  position, 
  but 
  the 
  tuberculate 
  pits 
  are 
  far 
  cephalad

   small,

  on 
  the

  of
