  Mr. 
  W. 
  Scliaus 
  on 
  

  

  mouth, 
  thin 
  and 
  scale-like, 
  blunt 
  at 
  the 
  extremity, 
  with 
  a 
  

   strong 
  molar 
  tooth 
  at 
  the 
  base. 
  The 
  maxilla 
  has 
  a 
  long 
  

   fleshy 
  outer 
  lobe 
  and 
  the 
  inner 
  lobe 
  is 
  strongly 
  chitinized 
  and 
  

   furnished 
  with 
  a 
  double 
  row 
  of 
  extremely 
  long 
  and 
  sharp 
  

   teeth. 
  The 
  mentum 
  is 
  quadrate, 
  with 
  a 
  terminal 
  fringe 
  of 
  

   long 
  hairs, 
  and 
  the 
  ligula 
  prominent 
  and 
  bilobed. 
  

  

  There 
  is 
  no 
  stridulatory 
  apparatus 
  such 
  as 
  characterizes 
  

   the 
  Orphninse, 
  Ochodseinse, 
  and 
  ldiostominse. 
  

  

  The 
  specimen 
  I 
  have 
  dissected 
  is 
  a 
  male, 
  but 
  I 
  have 
  found 
  

   no 
  external 
  sexual 
  distinction. 
  The 
  species 
  is 
  from 
  the 
  

   White 
  Nile 
  and 
  is 
  at 
  present 
  without 
  a 
  name. 
  It 
  is 
  ex- 
  

   tremely 
  close 
  to 
  Dynamopus 
  pUcifrons, 
  Fairm., 
  from 
  Senegal, 
  

   of 
  which 
  I 
  have 
  seen 
  the 
  type 
  in 
  M. 
  Hene 
  Oberthiir's 
  

   collection, 
  but 
  differs 
  in 
  having 
  the 
  pronotum 
  more 
  coarsely 
  

   and 
  less 
  densely 
  punctured. 
  Dynamopus 
  atkleta, 
  Sem., 
  of 
  

   Western 
  Asia, 
  is 
  a 
  rather 
  smaller 
  and 
  relatively 
  shorter 
  

   insect. 
  

  

  The 
  new 
  species 
  is 
  shortly 
  diagnosed 
  as 
  follows 
  :

  ; 
  prothorace

  grosse

  punctis

  confluentibus, 
  postice 
  discretis, 
  lateralitcr 
  sparsis,

  lateribus 
  fortiter 
  arcuatis,

  The 
  specimens 
  in 
  the 
  British 
  Museum 
  were 
  collected 
  

   many 
  years 
  ago 
  by 
  Mr. 
  Petherick. 
  The 
  species 
  is 
  also 
  con- 
  

   tained 
  in 
  Herr 
  Carl 
  Felsche's 
  collection.
