  old 
  specimens 
  of 
  ludlowi 
  lose 
  the 
  lustre 
  in 
  the 
  leg 
  spotting, 
  and 
  this 
  is 
  then 
  much 
  less 
  

   distinct, 
  while, 
  on 
  the 
  other 
  hand, 
  the 
  tawny 
  mottling 
  which 
  exists 
  in 
  rossi 
  is 
  rather 
  

   increased 
  in 
  dry 
  specimens, 
  owing 
  partly 
  to 
  contraction 
  of 
  the 
  scales 
  over 
  the 
  

   tawny-coloured 
  leg 
  and 
  partly 
  to 
  denudation. 
  

  

  We 
  thus 
  see 
  that 
  the 
  two 
  species, 
  ludlowi 
  and 
  rossi, 
  can 
  be 
  readily 
  distinguished 
  

   in 
  either 
  the 
  well-grown 
  larval 
  or 
  imaginal 
  stage. 
  It 
  is 
  satisfactory 
  that 
  this 
  is 
  so 
  

   with 
  regard 
  to 
  the 
  larva, 
  for 
  the 
  identification 
  of 
  the 
  larva 
  in 
  the 
  field 
  saves 
  much 
  

   trouble 
  and 
  is 
  preferable, 
  if 
  feasible, 
  to 
  breeding 
  out 
  the 
  imago.
