  Museum 
  by 
  the 
  Imperial 
  

   Bureau 
  of 
  Entomology. 
  

  

  This 
  species 
  is 
  very 
  distinct 
  from 
  all 
  others 
  yet 
  known 
  from 
  Africa 
  ; 
  in 
  position 
  

   it 
  seems 
  to 
  be 
  somewhat 
  intermediate 
  between 
  the 
  A. 
  marshalli 
  and 
  the 
  A. 
  tarsalis 
  

   group. 
  Its 
  nearest 
  ally 
  is 
  apparently 
  A. 
  lowisi, 
  Theo., 
  of 
  the 
  Andaman 
  Islands. 
  

  

  * 
  I 
  have 
  previously 
  (following 
  Dyar) 
  used 
  the 
  name 
  Ecculex 
  for 
  this 
  subgenus, 
  overlooking 
  

   the 
  fact 
  that 
  Theobald's 
  Aedimorphus 
  was 
  published 
  a 
  year 
  previously.
