  The 
  time 
  required 
  for 
  relaxation 
  varies 
  with 
  the 
  nature 
  

   of 
  the 
  beetle 
  and 
  its 
  condition. 
  

  

  A 
  Rhyncogonus 
  blackburni, 
  which 
  after 
  a 
  day 
  or 
  two 
  in 
  the 
  

   usual 
  relaxing 
  jar 
  it 
  was 
  impossible 
  to 
  mount 
  properly, 
  was 
  in 
  

   perfect 
  condition 
  for 
  mounting 
  in 
  thirty 
  minutes. 
  This 
  was 
  a 
  

   1902 
  specimen. 
  

  

  A 
  large 
  Cossonid 
  Nesotocus 
  munroi, 
  a 
  species 
  which 
  is 
  most 
  

   apt 
  to 
  assume 
  a 
  most 
  wiry 
  condition, 
  and 
  was 
  one 
  of 
  the 
  worst 
  

   samples 
  of 
  this 
  condition 
  I 
  have 
  ever 
  seen, 
  was 
  mounted 
  after 
  

   one 
  hour's 
  immersion, 
  but 
  less 
  easily 
  than 
  the 
  Rhyncogonus. 
  

   This 
  specimen, 
  however, 
  was 
  nine 
  or 
  ten 
  years 
  old, 
  had 
  been 
  

   collected 
  in 
  alcohol, 
  then 
  simply 
  pinned 
  with 
  all 
  the 
  legs 
  folded 
  

   up, 
  and 
  entangled; 
  and 
  subjected 
  to 
  the 
  fumes 
  of 
  carbolic 
  in 
  a 
  

   store 
  box 
  for 
  at 
  least 
  eight 
  years. 
  As 
  to 
  the 
  mouldy 
  specimens 
  

   the 
  treatment 
  was 
  first 
  given 
  to 
  some 
  moderate-sized 
  Carabids. 
  

   Every 
  particle 
  of 
  mould 
  brushed 
  off 
  with 
  ease, 
  and 
  relaxation 
  

   was 
  complete 
  in 
  thirty 
  minutes. 
  I 
  then 
  tried 
  smaller 
  species, 
  

   Bembidium, 
  with 
  similar 
  results. 
  The 
  surface 
  of 
  the 
  Carabidae 
  

   being 
  smooth, 
  I 
  then 
  took 
  mouldy 
  specimens 
  of 
  the 
  little 
  beetle 
  

   Antilissus 
  aper, 
  a 
  species 
  very 
  easily 
  injured. 
  The 
  resiilts 
  were 
  

   similar, 
  the 
  mould 
  was 
  removed 
  in 
  spite 
  of 
  the 
  rough 
  surface, 
  the 
  

   sculpture 
  and 
  setae 
  showing 
  again 
  in 
  the 
  most 
  perfect 
  manner. 
  

   The 
  most 
  obstinate 
  and 
  dirty 
  specimens 
  of 
  Dryophthorus 
  and 
  

   Oodemas 
  were 
  cleaned 
  to 
  a 
  degree 
  that 
  exhibited 
  the 
  clothing 
  or 
  

   sculpture 
  in 
  a 
  way 
  never 
  seen 
  in 
  specimens 
  taken 
  at 
  large. 
  I 
  

   exhibit 
  one 
  or 
  two 
  species 
  of 
  beetles 
  relaxed 
  and 
  cleaned 
  by 
  the 
  

   above 
  method, 
  not 
  as 
  samples 
  of 
  absolutely 
  accurate 
  mounting, 
  

   but 
  as 
  showing 
  what 
  can 
  be 
  done 
  with 
  apparently 
  hopeless 
  

   specimens.

  This 
  common

  also 
  in 
  

   other
