  A 
  number 
  of 
  species 
  of 
  this 
  genus 
  were 
  noticed 
  in 
  the 
  Tenth 
  Report 
  

   on 
  the 
  Injurious 
  a?td 
  Other 
  Insects 
  of 
  the 
  State 
  of 
  New 
  York, 
  and 
  two, 
  

   believed 
  to 
  be 
  new 
  to 
  science, 
  were 
  described. 
  During 
  the 
  present 
  year 
  

   several 
  other 
  forms 
  were 
  received 
  from 
  Dr. 
  J. 
  B. 
  Smith, 
  of 
  the 
  New 
  Jersey- 
  

   Agricultural 
  Experiment 
  Station, 
  who 
  had 
  bred 
  them 
  from 
  mushrooms^ 
  

   decaying 
  potatoes, 
  and 
  decaying 
  blackberry 
  roots. 
  On 
  his 
  request 
  they 
  

   have 
  been 
  given 
  some 
  study. 
  The 
  species 
  of 
  Sciara 
  are 
  so 
  similar 
  to 
  one 
  

   another 
  in 
  many 
  respects, 
  that 
  it 
  is 
  difficult 
  to 
  recognize 
  the 
  various 
  

   species 
  from 
  some 
  of 
  the 
  descriptions 
  published. 
  Those 
  bred 
  from 
  the 
  

   mushrooms 
  and 
  potatoes, 
  however, 
  do 
  not 
  agree 
  with 
  any 
  descriptions 
  

   accessible 
  to 
  me, 
  of 
  either 
  European 
  or 
  American 
  species 
  of 
  this 
  genus, 
  

   and 
  they 
  are 
  herewith 
  described 
  as 
  new 
  : 
  

  

  Sciara 
  multiseta

  antennae 
  brownish 
  with 
  a 
  thin 
  whitish 
  pubescence;

  wings 
  somewhat 
  iridescent, 
  hyaline, 
  anterior

  femur 
  darker, 
  tibia 
  still 
  darker, 
  and 
  tarsi 
  fuscous 
  distally. 
  

  

  Antennae 
  longer 
  than 
  the 
  head 
  and 
  thorax; 
  basal 
  segments 
  enlarged; 
  

   first, 
  cuboidal; 
  second, 
  globose; 
  third 
  to 
  fifteenth 
  nearly 
  cylindrical, 
  length, 
  

   about 
  twice 
  the 
  thickness, 
  pediceled 
  distally 
  ; 
  terminal 
  segment 
  conical. 
  

   Palpi 
  : 
  basal 
  segment 
  short

  scattering 
  large 
  setae 
  and 
  numerous 
  

   minute 
  ones 
  which 
  have 
  a 
  verticillate 
  arrangement 
  on 
  the 
  last 
  two 
  

   segments. 
  

  

  Thorax 
  with 
  scattering 
  hairs 
  ; 
  on 
  the 
  scutum

  the 
  mesothorax 
  there 
  

   are 
  three 
  rows 
  of 
  fine 
  setae 
  on 
  us 
  dorsal 
  surface. 
  

  

  Wings, 
  subcosta 
  (ist 
  longitudinal) 
  short, 
  not 
  extending 
  to 
  the 
  fork

   the 
  second 
  branch 
  of 
  radius

  First

  middle, 
  joined 
  

   by 
  the 
  small 
  cross-vein 
  to

  second 
  branch, 
  and 
  joining 
  costa 
  before 
  

   the 
  fork

  media. 
  Second

  of 
  radius 
  and 
  media,

  equidis- 
  

   tant

  of 
  the 
  wing. 
  Second

   nal) 
  and 
  the 
  two 
  branches 
  of 
  cubitus 
  (6th 
  and 
  7th 
  longitudinals) 
  reachmg 
  

   border 
  of 
  wing 
  at 
  nearly

   male
