  This 
  is 
  tlie 
  forty-first

  The 
  measurements 
  given 
  by 
  authors 
  in 
  this 
  and 
  other 
  

   families, 
  when 
  only 
  single 
  specimens 
  are 
  available, 
  are 
  some- 
  

   times 
  misleading 
  — 
  e.g., 
  1 
  have 
  now 
  an 
  example 
  of 
  Platylister 
  

   procerus 
  v^^hich 
  measures 
  11|^ 
  mm., 
  and 
  another 
  of 
  Macro- 
  

   lister 
  rohusticollis 
  which 
  measures 
  12^ 
  mm., 
  and 
  a 
  sj)ecinien 
  

   of 
  Proholosternus 
  africanus 
  of 
  9 
  mm. 
  The 
  orio-inal 
  records 
  

   were 
  8^-9, 
  9, 
  and 
  7 
  mm. 
  respectively. 
  The 
  size 
  oiveu 
  of 
  a 
  

   species 
  in 
  the 
  Histeridse 
  is 
  only 
  of 
  an 
  approximate 
  value, 
  but 
  

   it 
  is 
  essential 
  that 
  an 
  accurate 
  standard 
  should 
  be 
  maintained 
  

   in 
  using 
  words 
  such 
  as 
  ovalis, 
  ohlonc/o-ovalis, 
  subovalis, 
  

   h>-eviter-ovalis, 
  and 
  other 
  terms 
  employed 
  by 
  describers 
  in 
  

   indicating 
  the 
  outline 
  of 
  a 
  species.
