  than 
  one 
  undoubted 
  instance 
  known 
  ; 
  and, 
  when 
  such 
  is 
  

   the 
  case, 
  the 
  form 
  of 
  the 
  thorax 
  in 
  the 
  $ 
  approximates 
  to 
  

   that 
  of 
  the 
  females. 
  Such 
  is 
  certainly 
  the 
  case 
  with 
  M. 
  

   ccdipus, 
  in 
  which 
  I 
  am 
  not 
  only 
  unable 
  to 
  find 
  any 
  trace 
  of 
  

   there 
  having 
  been 
  wings, 
  but 
  so 
  far 
  as 
  the 
  hind 
  wings 
  are 
  

   concerned, 
  I 
  cannot 
  see 
  where 
  they 
  could 
  have 
  been 
  

   attached. 
  The 
  contracted 
  thorax 
  is 
  well 
  shown 
  in 
  my 
  

   figure 
  {Manch. 
  Memoirs, 
  vol.

  No.

  pi.

  A 
  

   comparison 
  of 
  my 
  figure 
  with 
  that 
  of 
  M. 
  perfecta 
  Rad., 
  

   shows 
  great 
  similarity 
  between 
  these 
  apterous 
  males 
  in 
  

   structure 
  of 
  the 
  thorax.*

  {Manch.

  in 
  both 
  sexes 
  by 
  me, 
  is 
  omitted 
  entirely 
  by 
  

   Bingham. 
  

  

  Col. 
  Bingham 
  also 
  has 
  overlooked 
  my 
  description 
  of 
  

   both 
  sexes 
  of 
  Mutilla 
  opulenta 
  {Manch. 
  Memoirs, 
  I.e., 
  

   P- 
  57). 
  

  

  Mutilla 
  apicipennis 
  Cam. 
  

  

  This 
  species 
  is 
  not 
  mentioned 
  by 
  Bingham 
  under 
  

   this 
  name, 
  unless 
  he 
  regards 
  it 
  as 
  identical 
  with 
  M. 
  

   pedunculata 
  Klug 
  {I.e., 
  p. 
  51). 
  If 
  so, 
  his 
  description 
  

   of 
  the 
  latter 
  is 
  defective 
  in 
  a 
  very 
  important 
  point, 
  

   namely, 
  he 
  says 
  nothing 
  about 
  the 
  petiole 
  being 
  serrate, 
  

   or 
  irregularly 
  armed 
  with 
  teeth 
  beneath, 
  this 
  being 
  one 
  of 
  

   the 
  most 
  specific 
  features 
  whereby 
  M 
  . 
  pedunculata 
  is 
  dis- 
  

   tinguished 
  from 
  the 
  very 
  closely-allied 
  M. 
  chlorotica 
  Grib. 
  

   I 
  have 
  not 
  at 
  hand 
  Klug's 
  original 
  description, 
  but 
  M. 
  

   apicipennis 
  does 
  not 
  agree 
  with 
  Gribodo's 
  description 
  of 
  

   M 
  . 
  pedunculata, 
  e.g., 
  the 
  second 
  abdominal 
  segment 
  is 
  not 
  

   coarsely 
  and 
  strongly 
  rugosely 
  punctured, 
  M. 
  apicipennis 
  

   having 
  it 
  only 
  irregularly 
  roughened 
  at 
  the 
  base 
  ; 
  in 
  M.
