  entering 
  the

  of 
  the

   margin, 
  the 
  outer 
  one 
  hardly 
  perceptibly 
  separated 
  from 
  an

  the

  Fringes

  plumule 
  

   of 
  hindwing 
  broadly 
  white

  whitish. 
  The

  white 
  before 
  the 
  apex 
  with 
  a 
  broad 
  

   spot 
  of 
  black-brown 
  scales. 
  This 
  species 
  is 
  distinguished 
  from 
  all 
  its 
  relatives 
  by 
  

   its 
  abnormal 
  ground-colour 
  ; 
  according 
  to 
  Dr. 
  Wocke, 
  it 
  occurs 
  also 
  in 
  the 
  south 
  

   of 
  France, 
  but 
  is 
  not 
  yet 
  described, 
  and 
  I 
  name 
  it 
  after 
  Graf 
  von 
  Hoffmannsegg. 
  

  

  Egglaying. 
  — 
  The 
  eggs 
  are 
  laid 
  singly, 
  on 
  the 
  hairs 
  on 
  the 
  upper 
  

   surface 
  of 
  the 
  leaves 
  of 
  Hieracium 
  pilosella, 
  about 
  halfway 
  up 
  the 
  hair, 
  or 
  a 
  

   little 
  higher. 
  On 
  June 
  24th, 
  1905, 
  I 
  took 
  a 
  ? 
  of 
  this 
  species, 
  and 
  two 
  

   or 
  three 
  $ 
  s. 
  They 
  were 
  swept 
  from 
  the 
  short 
  turf 
  in 
  places 
  where 
  

   H. 
  pilosella 
  was 
  growing. 
  The 
  moths 
  were 
  sleeved 
  over 
  a 
  plant 
  of 
  H. 
  

   pilosella 
  and 
  a 
  piece 
  of 
  thyme, 
  and, 
  on 
  June 
  29th, 
  at 
  4.15 
  p.m., 
  I 
  noticed 
  

   that 
  the 
  moths, 
  of 
  which 
  there 
  were 
  then 
  only 
  two 
  left, 
  were 
  paired. 
  The 
  

   $ 
  was 
  hanging 
  from 
  the 
  ? 
  in 
  the 
  usualAlucitid 
  manner, 
  but 
  was 
  also 
  cling- 
  

   ing 
  to 
  the 
  muslin 
  of 
  the 
  sleeve. 
  When 
  I 
  saw 
  them 
  again 
  at 
  7.40 
  p.m. 
  

   they 
  had 
  separated, 
  and 
  I 
  fancy 
  they 
  must 
  have 
  been 
  disturbed. 
  On 
  

   July 
  2nd, 
  ova 
  were 
  found 
  on 
  the 
  sleeved 
  plant 
  of 
  Hieracium, 
  but 
  none 
  

   on 
  the 
  thyme. 
  The 
  eggs 
  were 
  all 
  attached 
  to 
  the 
  long 
  hairs 
  (near 
  the 
  

   summit) 
  which 
  grow 
  on 
  the 
  upper 
  surface 
  of 
  the 
  Hieracium 
  leaves. 
  

   These 
  eggs 
  subsequently 
  proved 
  infertile, 
  but 
  they 
  showed 
  the 
  position 
  

   and 
  situation 
  in 
  which 
  this 
  species 
  lays 
  its 
  eggs. 
  Acting 
  on 
  the 
  know- 
  

   ledge 
  thus 
  gained, 
  I 
  visited 
  the 
  moth's 
  haunts, 
  fortunately 
  meeting 
  

   with 
  Dr. 
  Chapman 
  on 
  the 
  way. 
  After 
  some 
  searching 
  we 
  found, 
  in 
  all, 
  

   about 
  a 
  dozen 
  ova 
  on 
  the 
  Hieracium 
  leaves 
  in 
  the 
  position 
  above 
  

   described. 
  This 
  was 
  on 
  July 
  5th, 
  and 
  ten 
  days 
  later 
  I 
  took 
  a 
  few 
  more 
  

   ova 
  in 
  a 
  different 
  locality, 
  but 
  these 
  were 
  also 
  laid 
  in 
  the 
  same 
  position. 
  

   The 
  egg, 
  as 
  already 
  noted, 
  is 
  laid 
  singly 
  at 
  the 
  end 
  of 
  one 
  of 
  the 
  hairs, 
  

   on 
  the 
  upper 
  surface 
  of 
  the 
  leaf 
  of 
  H. 
  pilosella. 
  As 
  a 
  rule, 
  only 
  one 
  egg 
  is 
  

   laid 
  on 
  one 
  plant. 
  It 
  reminds 
  the 
  observer 
  superficially 
  of 
  the 
  egg 
  of 
  the 
  

   Lace 
  wing 
  fly, 
  which 
  is 
  laid 
  at 
  the 
  summit 
  of 
  a 
  long 
  egg- 
  stalk, 
  but 
  in 
  

   this 
  case 
  the 
  egg 
  is 
  not 
  laid 
  actually 
  on 
  the 
  apex, 
  but 
  along 
  the 
  ter- 
  

   minal 
  portion 
  of 
  the 
  hair, 
  so 
  that 
  it 
  stands 
  well 
  off 
  the 
  surface 
  of 
  the 
  

   leaf, 
  about 
  2mm. 
  That 
  portion 
  of 
  the 
  hair 
  to 
  which 
  the 
  egg 
  adheres 
  

   seems 
  to 
  be 
  of 
  the 
  same 
  colour 
  as 
  the 
  egg 
  itself 
  (? 
  the 
  effect 
  of 
  the 
  

   gum), 
  the 
  rest 
  of 
  the 
  hair 
  is 
  transparent. 
  The 
  egg 
  rests 
  with 
  its 
  

   longer 
  axis 
  parallel 
  to 
  the 
  hair 
  (Sich). 
  On 
  July 
  5th, 
  1905, 
  a 
  search 
  

   was 
  made 
  with 
  Mr. 
  Sich, 
  who 
  had 
  ascertained 
  that 
  the 
  eggs 
  were 
  laid 
  on 
  

   the 
  hairs 
  of 
  the 
  leaves 
  of 
  H. 
  pilosella 
  ; 
  we 
  both 
  found 
  several, 
  and 
  all 
  

   were 
  laid 
  about 
  midway 
  up 
  one 
  of 
  the 
  long 
  hairs 
  on 
  the 
  upperside 
  of 
  

   the 
  leaf; 
  the 
  hairs 
  beneath 
  may 
  also 
  have 
  them, 
  but 
  they 
  are 
  not 
  

   easily 
  searched. 
  Several 
  eggs 
  were 
  pale, 
  nearly 
  white, 
  the 
  majority 
  

   were 
  orange 
  ; 
  one 
  was 
  darker 
  and 
  already 
  showed 
  the 
  black 
  larval 
  

   head, 
  this 
  egg 
  hatched 
  on 
  July 
  6th. 
  A 
  2 
  taken 
  on 
  Reigate 
  Hill 
  only 
  

   laid 
  three 
  eggs, 
  one 
  being 
  ready 
  to 
  hatch 
  on 
  July 
  12th 
  (Chapman). 
  

   The 
  following 
  particulars 
  of 
  three 
  ova 
  observed 
  closely 
  may 
  be 
  

   interesting 
  :
