  This 
  genus 
  is 
  the 
  Old 
  World 
  representative 
  of 
  the 
  Thyreodon 
  group. 
  

   It 
  is 
  restricted 
  in 
  distribution 
  to 
  the 
  eastern 
  part 
  of 
  the 
  Palearctic 
  

   region 
  and 
  the 
  Oriental 
  region. 
  

  

  I 
  have 
  not 
  seen 
  the 
  genotype 
  of 
  Aglaophion 
  but 
  believe 
  I 
  am 
  correct 
  

   in 
  transferring 
  it 
  to 
  the 
  genus 
  Thyreodon 
  purpurascens 
  Smith, 
  as 
  which 
  

   I 
  have 
  identified 
  certain 
  specimens 
  in 
  the 
  United 
  States 
  National 
  

   Museum 
  from 
  China 
  and 
  Japan. 
  As 
  Hybopleurax 
  sumatranum 
  

   Enderlein 
  I 
  have 
  identified 
  a 
  specimen 
  in 
  the 
  United 
  States 
  National 
  

   Museum, 
  and 
  on 
  this 
  basis 
  synonymize 
  Hybopleurax 
  with 
  Aglaophion. 
  

   These 
  two 
  are 
  the 
  only 
  described 
  species 
  I 
  know, 
  aside 
  from 
  the 
  

   genotype, 
  that 
  are 
  referable 
  to 
  the 
  genus. 
  The 
  possible 
  synonymy 
  

   of 
  this 
  genus 
  with 
  Dictyonotus 
  Kriechbauxner 
  is 
  discussed 
  under 
  the 
  

   latter 
  genus. 
  

  

  From 
  the 
  other 
  genera 
  of 
  the 
  Thyreodon 
  group 
  tliis 
  genus 
  may 
  at 
  

   once 
  be 
  distinguished 
  by 
  its 
  complete 
  and 
  high 
  postpectoral 
  carina 
  

   (pi. 
  52, 
  fig. 
  36) 
  and 
  deeply 
  emarginato 
  tergites. 
  From 
  the 
  above 
  

   description 
  of 
  Thyreodon 
  it 
  also 
  differs 
  as 
  follows: 
  

  

  Head 
  (pi. 
  51, 
  fig. 
  34) 
  : 
  About 
  as 
  wide 
  as 
  thorax; 
  eyes 
  more 
  shallowly 
  

   emarginate; 
  malar 
  space 
  nearly 
  as 
  long 
  as 
  basal 
  width 
  of 
  mandible; 
  

   antennal 
  scrobes 
  shallow 
  and 
  less 
  distinctly 
  defined; 
  clypeus 
  rather 
  

   distinctly 
  separated, 
  recurved 
  but 
  rounded 
  at 
  apex; 
  second 
  joint 
  of 
  

   maxillary 
  palpus 
  clavate. 
  

  

  Thorax: 
  Pronotum 
  not 
  deeply 
  grooved 
  dorsally, 
  neither 
  anterior 
  nor 
  

   posterior 
  margin 
  prominent; 
  mesoscutum 
  hardly 
  precipitous 
  anteriorly, 
  

   notaulices 
  obsolete; 
  mesopleuron 
  (pi. 
  52, 
  fig. 
  46) 
  with 
  a 
  longitudinal 
  

   groove 
  or 
  impression 
  at 
  top 
  of 
  prepectus 
  dividing 
  the 
  pleuron 
  into 
  

   approximately 
  equal 
  upper 
  and 
  lower 
  areas; 
  sternaulices 
  obsolete; 
  

   metapleuron 
  strongly 
  convex, 
  frequently 
  tuberculate; 
  propodeum 
  

   (pi. 
  51, 
  fig. 
  30) 
  not 
  bulbous, 
  basal 
  constriction 
  only 
  moderatel3^ 
  deep, 
  

   spiracles 
  situated 
  behind 
  constriction. 
  Wings 
  with 
  lower 
  apical 
  angle 
  

   of 
  second 
  discoidal 
  cell 
  right 
  or 
  slightly 
  obtuse; 
  frenulum 
  much 
  shorter 
  

   and 
  with 
  comparatively 
  few 
  (about 
  10) 
  hooks; 
  cubitella 
  nearly 
  reach- 
  

   ing 
  margin 
  of 
  wing; 
  nervellus 
  broken 
  at 
  or 
  near 
  upper 
  third. 
  Legs
