  The 
  j^enus 
  ai)pareiitly 
  differs 
  from 
  all 
  others 
  treated 
  here, 
  except 
  

   Schtherellns 
  Masi. 
  by 
  having 
  the 
  head 
  and 
  thorax 
  distinctly 
  

   sculptured 
  instead 
  of 
  mostly 
  smooth 
  and 
  polished. 
  From 
  Seia- 
  

   fherfllii.s, 
  known 
  only 
  in 
  the 
  male 
  sex. 
  it 
  may 
  be 
  distinguished 
  by 
  

   the 
  characters 
  used 
  in 
  the 
  key. 
  

  

  The 
  antennae 
  are 
  said 
  to 
  be 
  clavate. 
  inserted 
  below 
  the 
  middle 
  

   of 
  face 
  but 
  a 
  little 
  above 
  a 
  line 
  connecting 
  the 
  lower 
  extremities 
  

   of 
  the 
  eyes. 
  10-segmented, 
  without 
  a 
  ring 
  segment, 
  the 
  funicle 
  

   6-segmented 
  and 
  the 
  club 
  indistinctly 
  2-segmented. 
  The 
  head, 
  

   viewed 
  from 
  in 
  front, 
  is 
  nearly 
  as 
  broad 
  as 
  long, 
  the 
  eyes 
  promi- 
  

   nent, 
  and 
  the 
  cheeks 
  curved. 
  The 
  axillae 
  are 
  rugoso-sulcate. 
  and 
  

   the 
  scutellum 
  similarly 
  but 
  less 
  strongly 
  sculptured. 
  The 
  propo- 
  

   deum 
  has 
  a 
  deep, 
  semielliptical. 
  transverse 
  excavation 
  basally. 
  

   The 
  forewing 
  is 
  without 
  a 
  tuft 
  of 
  hairs 
  at 
  the 
  juncture 
  of 
  marginal 
  

   and 
  submarginal 
  veins, 
  the 
  marginal 
  vein 
  is 
  about 
  eight 
  times 
  as 
  

   long 
  as 
  the 
  rather 
  short 
  stigmal 
  vein, 
  the 
  stigmal 
  knob 
  is 
  armed 
  

   with 
  a 
  short 
  tooth, 
  and 
  the 
  postmarginal 
  vein 
  is 
  a 
  little 
  shorter 
  

   than 
  the 
  stigmal. 
  The 
  wing 
  beyond 
  the 
  basal 
  cell 
  is 
  said 
  to 
  be 
  

   yellowish 
  gray 
  ("flavido-grisescentes") 
  with 
  the 
  transverse 
  fascia 
  

   behind 
  the 
  juncture 
  of 
  marginal 
  and 
  submarginal 
  veins 
  and 
  the 
  

   macula 
  adjacent 
  to 
  the 
  stigmal 
  vein 
  obscure, 
  the 
  apical 
  margin 
  

   pallid. 
  The 
  abdominal 
  petiole 
  is 
  almost 
  as 
  long 
  as 
  the 
  propodeum, 
  

   cylindrical 
  and 
  finely 
  striated, 
  and 
  the 
  gaster 
  is 
  about 
  as 
  long 
  as 
  

   thorax, 
  smooth 
  and 
  shining, 
  its 
  first 
  segment 
  not 
  incised 
  at 
  dorsal 
  

   margin. 
  The 
  ovipositor 
  is 
  exserted 
  one-third 
  the 
  length 
  of 
  gaster.

  The 
  type 
  species, 
  S. 
  orncinxs 
  Masi. 
  described 
  in 
  the 
  same 
  paper 
  

   as 
  the 
  genus, 
  was 
  based 
  on 
  a 
  single 
  male 
  specimen 
  collected 
  in 
  the 
  

   Seychelles 
  Islands. 
  

  

  This 
  genus, 
  like 
  Neoscuitheras 
  Masi, 
  apparently 
  differs 
  from 
  

   the 
  other 
  genera 
  in 
  this 
  group 
  by 
  having 
  the 
  mesonotum 
  punctate. 
  

   It 
  differs 
  from 
  Meosciatheras 
  according 
  to 
  the 
  de.scription 
  by 
  hav- 
  

   ing 
  the 
  stigmal 
  vein 
  about 
  one-fourth 
  as 
  long 
  as 
  the 
  marginal. 
  

   the 
  stigmal 
  knob 
  only 
  slightly 
  developed 
  and 
  without 
  a 
  process, 
  

   the 
  postmarginal 
  vein 
  almost 
  effaced, 
  the 
  antennae 
  inserted 
  a 
  

   little 
  above 
  the 
  middle 
  of 
  head, 
  the 
  scape 
  extending 
  above 
  thf 
  

   level 
  of 
  vertex, 
  the 
  flagellum 
  very 
  long 
  and 
  not 
  thickened, 
  and 
  the 
  

   propodeum 
  without 
  a 
  transverse 
  fovea 
  at 
  base. 
  The 
  forewing 
  is 
  

   without 
  a 
  tuft 
  of 
  bristles 
  at 
  the 
  juncture 
  of 
  marginal 
  and 
  sub- 
  

   marginal 
  veins 
  and 
  has 
  two 
  transverse 
  fuscous 
  bands. 
  The 
  head, 
  

   viewed 
  from 
  in 
  front, 
  is 
  a 
  little 
  broader 
  than 
  long, 
  and 
  the 
  face 
  is 
  

   obliquely 
  striate 
  without 
  projections.
