  J.

  Perkins 
  examined 
  the 
  type 
  and 
  made 
  the 
  following 
  notes 
  

   comparing 
  the 
  species 
  with 
  Aglaophion 
  flavinervis: 
  "Differs 
  in 
  having 
  

   the 
  mandible 
  in 
  front 
  of 
  a 
  line 
  joining 
  the 
  base 
  anteriorly 
  to 
  the 
  V 
  

   between 
  the 
  teeth, 
  strongly 
  depressed; 
  clypeus 
  conspicuously, 
  though 
  

   not 
  strongly, 
  outwardly 
  reflexed 
  in 
  the 
  apical 
  one-third 
  (at 
  an 
  angle 
  

   of 
  about 
  150°) 
  ; 
  ocular 
  carina 
  of 
  the 
  same 
  form 
  as 
  in 
  Euryophion, 
  but 
  

   the 
  weak 
  groove 
  to 
  the 
  ocelli 
  is 
  not 
  interrupted; 
  propodeum 
  and 
  meta- 
  

   pleura 
  of 
  the 
  same 
  form 
  as 
  in 
  Aglaophion, 
  but 
  a 
  httle 
  shorter, 
  tergites 
  

   3-5 
  weakly 
  excised 
  apically."

  This 
  African 
  genus 
  is 
  unknown 
  to 
  me, 
  and 
  I 
  should 
  have 
  been 
  

   unable 
  to 
  place 
  it 
  without 
  the 
  assistance 
  of 
  J. 
  F. 
  Perkins. 
  With 
  this 
  

   assistance 
  I 
  place 
  it, 
  I 
  think 
  satisfactorily, 
  in 
  the 
  Thyreodon 
  group, 
  

   where 
  it 
  appears 
  to 
  be 
  the 
  South 
  African 
  analog 
  of 
  Aglaophion. 
  The 
  

   following 
  description 
  is 
  compounded 
  of 
  the 
  characters 
  given 
  by 
  

   Cameron 
  and 
  Morley 
  together 
  with 
  those 
  furnished 
  by 
  Mr. 
  Perkins: 
  

  

  Large 
  insects, 
  exceeding 
  25 
  mm. 
  in 
  length, 
  entirely 
  black 
  wings. 
  

  

  Head: 
  Strongly 
  swollen 
  behind 
  eyes; 
  occipital 
  carina 
  with 
  a 
  median 
  

   notch 
  directed 
  toward 
  the 
  neck; 
  frons 
  margined 
  by 
  carinae 
  both 
  be- 
  

   low 
  and 
  at 
  sides, 
  carina 
  at 
  side 
  of 
  frons 
  extraordinarily 
  raised 
  and 
  

   continued 
  to 
  posterior 
  ocellus 
  by 
  a 
  groove 
  which 
  runs 
  from 
  eye 
  to 
  

   front 
  of 
  posterior 
  ocellus, 
  the 
  carina 
  and 
  groove 
  interrupted 
  shortly 
  

   before 
  ocellus 
  by 
  a 
  short, 
  deep, 
  transverse 
  fiU"row; 
  clypeus 
  medially 
  

   reflexed 
  and 
  truncate; 
  mandibles 
  broad, 
  not 
  conspicuously 
  twisted; 
  

   eyes 
  parallel 
  and 
  not 
  emarginate; 
  ocelli 
  small; 
  mandibles 
  short 
  and 
  

   broad, 
  only 
  slightly 
  twisted; 
  antenna 
  thick, 
  tapering 
  and 
  about 
  as 
  

   long 
  as 
  forewing. 
  

  

  Thorax: 
  Mesoscutum 
  with 
  a 
  shallow 
  median 
  longitudinal 
  furrow, 
  

   notauHces 
  obsolete; 
  scutellum 
  not 
  margined; 
  postscutellum 
  elevated; 
  

   mesosternum 
  flat, 
  sternauUces 
  shallow 
  anteriorly, 
  deep 
  posteriorly; 
  

   postpectoral 
  carina 
  complete, 
  but 
  difficult 
  to 
  see 
  ventrally 
  as 
  it 
  

   runs 
  close 
  to 
  the 
  coxae; 
  metapleuron 
  with 
  a 
  large 
  tubercle 
  in 
  middle; 
  

   propodeum 
  not 
  longer 
  than 
  broad, 
  not 
  conspicuously 
  intumescent
