  Adult 
  £, 
  when 
  mounted, 
  elongate, 
  narrowly 
  rounded 
  in 
  front, 
  broadest 
  immediately 
  

   behind 
  the 
  middle, 
  and 
  somewhat 
  broadly 
  pointed 
  behind, 
  hyaline, 
  with 
  the 
  pygidium 
  

   slightly 
  denser 
  ; 
  abdominal 
  segments 
  well 
  marked 
  and 
  flatly 
  rounded 
  at 
  the 
  margin. 
  

   Pygidium 
  without 
  lobes 
  or 
  plates, 
  coarsely 
  corrugate, 
  with 
  conspicuous 
  spines 
  and 
  

   dorsal 
  glands 
  as 
  illustrated 
  (fig. 
  178). 
  Circumgenital 
  glands 
  in 
  5 
  groups, 
  which 
  are 
  

   often 
  almost 
  contiguous 
  in 
  a 
  wide 
  bow

  Remarks. 
  — 
  This 
  species 
  is 
  very 
  much 
  like 
  C. 
  simplex 
  Green, 
  and 
  is 
  in 
  all 
  probability 
  

   the 
  variety 
  he 
  mentions 
  from 
  Mauritius 
  ; 
  it 
  has 
  but 
  5 
  groups 
  of 
  circumgenital 
  glands 
  

   instead 
  of 
  7 
  as 
  in 
  C. 
  simplex.
