  The 
  preapical 
  tibial 
  spur 
  of 
  the 
  fore 
  legs 
  short 
  and 
  weak 
  ; 
  the 
  spur 
  of 
  the 
  second 
  

   tibia 
  long 
  and 
  saltatorial, 
  reaching 
  to 
  the 
  middle 
  of 
  the 
  second 
  tarsal 
  joint 
  ; 
  the 
  

   subapical 
  femoral 
  spurs 
  of 
  the 
  same 
  leg 
  strong 
  ; 
  the 
  tibial 
  spur 
  of 
  third 
  leg 
  strong 
  and 
  

   short, 
  with 
  a 
  comb 
  of 
  seven 
  short 
  spines 
  on 
  inner 
  aspect. 
  

  

  Length, 
  1*25 
  mm. 
  ; 
  alar 
  expanse, 
  nearly 
  2*5 
  mm. 
  

  

  Described 
  from 
  a 
  single 
  female, 
  bred 
  3., 
  viii., 
  1914. 
  

  

  Host 
  : 
  the

  Genus 
  Sympiesis, 
  Forst. 
  

  

  The 
  following 
  species 
  is 
  apparently 
  congeneric 
  with 
  Sympiesis 
  felti, 
  Crawford, 
  

   (Proc. 
  U.S. 
  Nat. 
  Mus., 
  xl. 
  p. 
  448, 
  1911), 
  described 
  from 
  Agromyza 
  melanopyga 
  in 
  

   fern 
  leaves. 
  In 
  the 
  single 
  <$ 
  present 
  in 
  the 
  material 
  the 
  frons 
  had 
  been 
  injured 
  

   and 
  the 
  antennae 
  crushed 
  off 
  at 
  the 
  scape. 
  Two 
  chitinous 
  fragments 
  adhering 
  to 
  the 
  

   face 
  were 
  detached, 
  and 
  after 
  treating 
  with 
  potash 
  followed 
  by 
  glacial 
  acetic 
  acid, 
  

   were 
  sufficiently 
  swollen 
  to 
  be 
  identified 
  as 
  the 
  first 
  and 
  second 
  funicular 
  joints 
  ; 
  

   neither 
  was 
  furnished 
  with 
  a 
  branch 
  or 
  unusually 
  long 
  hair. 
  All 
  the 
  generic 
  

   characters 
  are, 
  I 
  think, 
  distinctly 
  marked, 
  except 
  in 
  the 
  condition 
  of 
  the 
  hind 
  tibia, 
  

   which 
  unless 
  carefully 
  examined, 
  might 
  be 
  taken 
  as 
  indicating 
  a 
  Hemitarsenine 
  

   affinity. 
  The 
  second 
  spur, 
  however, 
  though 
  short, 
  is 
  undoubtedly 
  present. 
  

   Sympiesis 
  purpureus 
  is 
  a 
  purplish 
  black 
  form, 
  with 
  duller 
  thorax 
  and 
  entirely 
  

   dark 
  antennae. 
  The 
  abdomen 
  shows 
  bluer 
  reflections. 
  The 
  legs 
  are 
  pale, 
  with 
  

   darker 
  tarsal 
  tips 
  and 
  femoral 
  streaks.

  $. 
  — 
  Head 
  much 
  broader 
  than 
  deep 
  (4:3), 
  eyes 
  bare, 
  swollen 
  and 
  prominent. 
  Vertex, 
  

   frons 
  and 
  clypeus 
  shining, 
  without 
  pattern 
  (except 
  within 
  the 
  ocellar 
  triangle) 
  ; 
  

   aerobes 
  roughly 
  circular, 
  or 
  square 
  with 
  rounded 
  angles 
  ; 
  a 
  narrow 
  linear 
  ridge 
  

   between 
  the 
  mouth 
  corner 
  and 
  the 
  lower 
  eye 
  angle 
  ; 
  clypeal 
  edge 
  simple, 
  concave. 
  

   Occiput 
  reticulate, 
  with 
  a 
  few 
  short 
  bristles. 
  At 
  each 
  side 
  of 
  the 
  vertex 
  two 
  bristles 
  ; 
  

   posterior 
  ocelli 
  wide 
  apart 
  near 
  the 
  occipital 
  edge, 
  with 
  four 
  bristles 
  between 
  and 
  one 
  

   in 
  front 
  of 
  each 
  ; 
  along 
  the 
  orbits 
  about 
  10 
  minute 
  bristles. 
  Frons 
  remarkably 
  bare. 
  

   Before 
  the 
  narrow 
  ridge 
  separating 
  the 
  face 
  from 
  the 
  genae 
  are 
  two 
  minute 
  bristles, 
  

   and 
  four 
  more 
  stand 
  in 
  a 
  square 
  above 
  the 
  middle 
  of 
  the 
  mouth 
  edge. 
  Although 
  

   the 
  surface 
  of 
  the 
  face 
  is 
  uniformly 
  smooth, 
  there 
  is 
  an 
  internal 
  reticulation 
  of 
  the 
  

   integument 
  demonstrable 
  by 
  focussing 
  through. 
  Behind 
  the 
  malar 
  keel 
  there 
  is 
  a 
  

   distinct, 
  curved, 
  elongate 
  reticulation, 
  and 
  the 
  usual 
  row 
  of 
  post-ocular 
  bristles. 
  

  

  Antennae 
  (fig. 
  4, 
  a) 
  with 
  scape, 
  pedicel, 
  ring 
  joints, 
  four 
  funicular, 
  and 
  two 
  club 
  

   joints. 
  Scape 
  long 
  and 
  narrow 
  (5:1) 
  ; 
  pedicel 
  transverse, 
  hardly 
  wider 
  than 
  the 
  

   scape 
  and 
  extremely 
  short 
  (one-fifth 
  of 
  the 
  scape 
  or 
  one-half 
  the 
  first 
  funicular 
  

   joint), 
  with 
  a 
  reticulation 
  so 
  coarse 
  that 
  one 
  cell 
  extends 
  almost 
  the 
  length 
  of 
  the 
  

   joint 
  ; 
  ring 
  joints 
  (two) 
  minute, 
  narrow, 
  closely 
  appressed. 
  Joints 
  of 
  funicle 
  equal, 
  

   the 
  first 
  distinctly, 
  the 
  second 
  almost, 
  cylindrical 
  ; 
  joints 
  3 
  and 
  4 
  appear 
  slightly 
  

   shorter, 
  as 
  their 
  distal 
  angles 
  are 
  rounded 
  off 
  and 
  the 
  joint 
  produced 
  into 
  a 
  neck. 
  

   Club 
  not 
  expanded,

  the 
  joint 
  of 
  the 
  funicle 
  ; 
  basal 
  

   joint 
  a 
  little 
  longer 
  than 
  the 
  apical 
  one, 
  which 
  has 
  a 
  short, 
  blunt 
  spur. 
  The 
  whole 
  

   antennae 
  bristly 
  and 
  the 
  flanges 
  of 
  the 
  sensoria 
  stout. 
  Length 
  of
