  Fore 
  coxa 
  a 
  little 
  over 
  one-half 
  the 
  length 
  of 
  femur 
  or 
  tibia, 
  tarsi 
  

   about 
  one-fourth 
  longer, 
  first 
  segment 
  nearly 
  equal 
  to 
  the 
  remaining 
  seg- 
  

   ments 
  ; 
  middle 
  legs 
  nearly 
  the 
  same; 
  posterior 
  tibia 
  one-fourth 
  longer 
  

   than 
  the 
  slightly 
  elongated 
  femur; 
  first 
  segment 
  of 
  tarsi 
  equal 
  in 
  length 
  

   to 
  the 
  remaining 
  segments. 
  

  

  Abdomen 
  of 
  both 
  sexes 
  sparsely 
  invested 
  with 
  setse. 
  The 
  abdomen 
  

   of 
  the 
  female 
  enlarges 
  sHghtly 
  to 
  the 
  fourth 
  segment, 
  from 
  which 
  it 
  

   tapers 
  moderately 
  to 
  the 
  slender 
  ovipositor; 
  the 
  terminal 
  portion 
  of 
  

   the 
  genital 
  plates 
  oval. 
  

  

  Abdomen 
  of 
  the 
  male 
  nearly 
  cylindrical 
  and 
  bearing 
  the 
  usual 
  en- 
  

   larged 
  segment 
  with 
  claspers 
  which 
  are 
  terminated 
  by 
  a 
  single 
  stout 
  curved 
  

   spine. 
  The 
  setae 
  are 
  thickest 
  on 
  the 
  claspers, 
  especially 
  on 
  the 
  apical 
  

   portion 
  and 
  along 
  the 
  inner 
  margin. 
  On 
  the 
  median 
  line 
  of 
  the 
  ventral 
  

   sclerite 
  of 
  the 
  last 
  segment 
  there 
  is 
  a 
  sparse 
  group 
  of 
  stout 
  setae, 
  each 
  

   arising 
  from 
  an 
  enlarged 
  base 
  (PL 
  VI, 
  fig. 
  12). 
  Near 
  the 
  basal 
  third 
  of 
  

   the 
  clasper 
  there 
  is 
  a 
  very 
  long 
  seta 
  on 
  its 
  inner 
  margin, 
  extending 
  nearly 
  

   to 
  the 
  median 
  hne. 
  There 
  is 
  also 
  a 
  pair 
  of 
  long 
  stout 
  setae, 
  a 
  dorsal 
  and 
  

   a 
  ventral 
  one, 
  at 
  the 
  base 
  of 
  each 
  clasper. 
  

  

  Length: 
  male, 
  body 
  2.75 
  mm., 
  wing 
  2.5 
  mm.; 
  female, 
  body 
  3.5 
  m.m.^ 
  

   wing 
  3 
  mm. 
  

  

  This 
  species 
  may 
  be 
  separated 
  from 
  the 
  preceding 
  by 
  the 
  darker 
  color 
  

   of 
  the 
  palpi, 
  thorax, 
  and 
  abdomen, 
  by 
  the 
  greater 
  length 
  of 
  the 
  third 
  

   antennal 
  segment, 
  and 
  by 
  the 
  few 
  setae 
  in 
  the 
  group 
  on 
  the 
  median 
  line 
  

   of 
  the 
  ventral 
  sclerite 
  of 
  the 
  terminal 
  segment 
  in 
  the 
  male. 
  

  

  Numerous 
  small 
  flies 
  of 
  this 
  genus 
  were 
  found 
  in 
  the 
  mushroom 
  cellar 
  

   of 
  Dr. 
  Wm. 
  Hailes, 
  of 
  Albany, 
  N. 
  Y., 
  June 
  6, 
  1896. 
  It 
  was 
  stated 
  that 
  

   at 
  times 
  the 
  cellar 
  would 
  be 
  almost 
  black 
  with 
  this 
  and 
  other 
  species, 
  

   although 
  they 
  were 
  by 
  no 
  means 
  so 
  abundant 
  w^hen 
  the 
  cellar 
  was 
  visited 
  

   by 
  me. 
  With 
  the 
  advent 
  of 
  hot 
  weather 
  the 
  flies 
  become 
  so 
  numerous 
  

   as 
  to 
  destroy 
  the 
  mushrooms 
  quickly 
  and 
  render 
  their 
  further 
  culture 
  

   unprofitable. 
  

  

  The 
  flies 
  agree 
  with 
  no 
  description 
  of 
  American 
  forms 
  known 
  to 
  me. 
  

   The 
  species 
  is 
  evidently 
  closely 
  related 
  to 
  Sciara 
  villosa 
  Winnertz, 
  though 
  

   apparently 
  diflerent.
