  Mr. 
  H. 
  E. 
  Aiidrewes 
  on 
  the 
  

  

  his 
  Catascopus 
  elegans, 
  but 
  it 
  did 
  not 
  strike 
  him 
  that 
  

   it 
  belonged 
  more 
  properly 
  to 
  his 
  own 
  next 
  succeeding 
  

   genus. 
  Castelnau 
  redescribed 
  it 
  as 
  Catascopus 
  quadrisig- 
  

   ■natus 
  (Ann. 
  Soc. 
  Ent. 
  Fr. 
  1832, 
  392). 
  Chaudoir 
  proposed 
  

   a 
  new 
  genus, 
  Coeloprosopus, 
  for 
  the 
  species 
  (Bull. 
  Mosc. 
  

   1842, 
  iv, 
  840), 
  but 
  subsequently 
  withdrew 
  it 
  (Berl. 
  Ent. 
  

   Zeit. 
  1861, 
  123). 
  The 
  descriptions 
  of 
  Macleay 
  and 
  Castel- 
  

   nau 
  are 
  both 
  so 
  short 
  that 
  I 
  give 
  a 
  rather 
  more 
  detailed 
  

   one.-
