  This 
  is 
  the 
  American 
  analog 
  of 
  Siauropoctonus 
  Brauns, 
  with 
  which 
  

   it 
  shares 
  all 
  the 
  most 
  anomalous 
  characters, 
  but 
  it 
  is 
  immediately 
  

   distinguishable 
  by 
  its 
  entire 
  lack 
  of 
  the 
  postpectoral 
  carina 
  and 
  differs 
  

   further 
  as 
  follows: 
  

  

  Temples 
  (pi. 
  50, 
  fig. 
  13) 
  weakly 
  convex 
  and 
  exceedingly 
  narrow; 
  

   eyes 
  strongly 
  convergent 
  below 
  emargination 
  ; 
  clypeus 
  more 
  strongly 
  

   rounded 
  at 
  apex, 
  not 
  or 
  barely 
  exposing 
  labrum; 
  pronotal 
  sinus 
  very 
  

   broad; 
  scutellum 
  subquadrate, 
  not 
  margined 
  basally; 
  longitudinal 
  

   impression 
  of 
  mesopleuron 
  (pi. 
  52, 
  fig. 
  49) 
  m 
  the 
  form 
  of 
  a 
  narrow 
  

   groove; 
  postpectoral 
  carma 
  entirely 
  lacking; 
  propodeum 
  with 
  basal 
  

   and 
  apical 
  carinae 
  complete 
  to 
  entirely 
  lacking; 
  forewing 
  (pi. 
  54, 
  

   fig. 
  58) 
  with 
  hairless 
  area 
  extending 
  along 
  base 
  of 
  radius, 
  extreme 
  

   base 
  of 
  radial 
  cell 
  also 
  hau-less; 
  discocubitus 
  sharply 
  curved 
  or 
  sub- 
  

   angulate 
  at 
  about 
  middle, 
  straight 
  basally 
  and 
  weakly 
  curved 
  apically, 
  

   basal 
  portion 
  strongly 
  convergent 
  with 
  basal 
  vein; 
  lov/er 
  outer 
  angle 
  

   of 
  second 
  discoidal 
  cell 
  sharply 
  acute; 
  nervulus 
  antefurcal 
  to 
  inter- 
  

   stitial; 
  postnervulus 
  broken 
  far 
  above, 
  nervelius 
  far 
  below, 
  middle; 
  

   petiole 
  flattened 
  dorsally; 
  tergite 
  2 
  with 
  lateral 
  grooves 
  broad 
  and 
  

   shallow, 
  epipleura 
  not 
  infolded, 
  separated 
  only 
  basally 
  and 
  there 
  

   only 
  by 
  thinner 
  texture. 
  Agreeing 
  otherwise
