  I 
  would 
  also 
  like 
  to 
  call 
  attention 
  to 
  the 
  food-plant 
  of 
  the 
  

   larva 
  of 
  D. 
  barrettii. 
  The 
  principal 
  food-plant 
  is 
  rock 
  spurrey, 
  

   Spergularia 
  rupestris, 
  and 
  not 
  Silene 
  maritima. 
  The 
  rock 
  

   spurrey 
  grows 
  in 
  the 
  crevices 
  of 
  the 
  rocks 
  amongst 
  the 
  Silene 
  ; 
  

   it 
  makes 
  a 
  very 
  large 
  tap-root, 
  and 
  in 
  this 
  the 
  larva 
  feeds. 
  

   My 
  brother 
  first 
  discovered 
  it, 
  and 
  quite 
  by 
  accident. 
  We 
  were 
  

   searching 
  amongst 
  Silene 
  to 
  see 
  if 
  we 
  could 
  find 
  the 
  larvae, 
  

   when 
  he 
  noticed 
  a 
  withered 
  plant 
  of 
  spurrey, 
  which 
  broke 
  

   off 
  when 
  he 
  touched 
  it. 
  He 
  noticed 
  that 
  a 
  larva 
  had 
  been 
  

   feeding 
  just 
  under 
  the 
  crown, 
  and 
  called 
  my 
  attention 
  to 
  it. 
  

   We 
  dug 
  out 
  the 
  root 
  and 
  the 
  larva 
  was 
  in 
  it. 
  Nearly 
  every 
  

   plant 
  of 
  spurrey 
  was 
  infected 
  in 
  this 
  locality. 
  The 
  larva 
  

   does 
  sometimes 
  feed 
  on 
  Silene, 
  but 
  prefers 
  the 
  spurrey 
  ; 
  where 
  

   the 
  latter 
  occurs 
  it 
  can 
  be 
  taken 
  in 
  some 
  numbers. 
  It 
  leaves 
  

   the 
  plant 
  when 
  full 
  fed 
  and 
  pupates 
  just 
  under 
  the 
  surface 
  

   on 
  the 
  rocky 
  ledges. 
  Rock 
  spurrey 
  being 
  a 
  very 
  local 
  plant 
  

   no 
  doubt 
  accounts 
  for 
  the 
  scarcity 
  of 
  the 
  insect 
  in 
  many 
  

   apparently 
  suitable 
  localities. 
  Spurrey 
  likes 
  to 
  grow 
  right 
  

   on 
  the 
  cliff 
  face 
  if 
  it 
  can, 
  and 
  in 
  some 
  places 
  is 
  quite 
  inaccessible 
  

   except 
  by 
  being 
  let 
  over 
  the 
  clifE 
  by 
  a 
  rope.
