  forbid 
  its 
  occurrence 
  in 
  Britain, 
  we 
  add 
  Hofmann's 
  lifehistory 
  of 
  the 
  

   species 
  (as 
  known 
  in 
  Germany). 
  This 
  reads 
  as 
  follows: 
  — 
  Larva: 
  

   9mm. 
  long 
  ; 
  yellowish-green, 
  pale 
  green, 
  or 
  yellowish 
  ; 
  dorsal 
  tubercles; 
  

   pale 
  brownish 
  to 
  brown-red, 
  on 
  both 
  sides 
  bordered 
  with 
  rose-red, 
  or 
  

   blood-red, 
  or 
  even 
  brown-red, 
  elongate 
  spots. 
  The 
  dorsal 
  vessel 
  

   beneath 
  the 
  skin 
  appears 
  blackish, 
  or 
  dark 
  green, 
  though 
  sometimes 
  

   even 
  blood-red, 
  sometimes 
  edged 
  on 
  each 
  side 
  by 
  a 
  pale 
  yellowish 
  

   longitudinal 
  line. 
  The 
  small 
  heart-shaped 
  head 
  is 
  brown 
  previously 
  

   to 
  the 
  last 
  ecdysis 
  ; 
  afterwards 
  clear 
  honey-colour 
  with 
  dark 
  mouth 
  - 
  

   parts, 
  sometimes 
  also 
  green. 
  The 
  prothoracic 
  shield, 
  shining 
  brownish 
  

   before 
  the 
  last 
  ecdysis, 
  sometimes 
  made 
  up 
  of 
  three 
  spots, 
  disappears 
  

   afterwards 
  ; 
  spiracles 
  ringed 
  with 
  brown 
  ; 
  anal 
  shield 
  bright 
  brownish- 
  

   yellow, 
  dark 
  brown 
  on 
  the 
  sides 
  ; 
  all 
  the 
  legs 
  of 
  the 
  general 
  colour 
  of 
  

   the 
  body 
  ; 
  ventral 
  claspers 
  long, 
  stilt-like. 
  Habits 
  of 
  larva 
  : 
  It 
  lives 
  

   at 
  the 
  end 
  of 
  May 
  and 
  in 
  June 
  in 
  the 
  terminal 
  shoots 
  of 
  Hieracium 
  

   nmbellatum, 
  which 
  are 
  spun 
  up 
  in 
  longish 
  bunches, 
  in 
  which 
  the 
  larva 
  

   eats 
  the 
  innermost 
  leaves 
  and 
  deposits 
  its 
  excrement 
  ; 
  [the 
  larva 
  also 
  

   occurs 
  on 
  Picris 
  hieracoides* 
  and 
  Teucrium 
  seorodonia* 
  (according 
  to 
  

   Sorhagen, 
  p. 
  4), 
  unless, 
  with 
  regard 
  to 
  the 
  latter 
  plant, 
  a 
  mistake 
  has 
  

   been 
  made 
  with 
  another 
  species, 
  perhaps 
  0. 
  teucrii.] 
  Dr. 
  Steudel, 
  of 
  

   Stuttgart, 
  once 
  bred 
  an 
  example, 
  probably 
  of 
  this 
  species 
  (on 
  account 
  

   of 
  the 
  crippling 
  of 
  the 
  hind 
  wings 
  not 
  exactly 
  identified), 
  on 
  July 
  25 
  th 
  

   from 
  the 
  flowers 
  of 
  Hieracium 
  boreale. 
  Pupation 
  : 
  The 
  pupation 
  takes 
  

   place 
  on 
  a 
  stalk, 
  or 
  on 
  the 
  upperside 
  of 
  the 
  leaf, 
  beside 
  the 
  midrib, 
  etc. 
  

   Pupa 
  : 
  9mm. 
  long, 
  anteriorly 
  bluntly 
  rounded, 
  w 
  7 
  ith 
  very 
  short, 
  blunt, 
  

   frontal 
  prominence, 
  and 
  slight 
  dorsal 
  keels 
  ; 
  these 
  are 
  furnished, 
  on 
  the 
  

   metathorax, 
  each 
  with 
  three 
  small 
  teeth 
  directed 
  forwards 
  ; 
  on 
  the 
  

   dorsum 
  of 
  the 
  abdomen 
  there 
  are 
  laterally 
  compressed 
  elevations 
  

   terminating 
  in 
  one 
  point 
  on 
  the 
  first 
  and 
  last 
  segment 
  but 
  one, 
  and 
  in 
  

   two 
  points 
  on 
  the 
  remaining 
  segments 
  ; 
  they 
  carry, 
  at 
  their 
  bases, 
  a 
  

   white 
  bristle 
  directed 
  forwards 
  and 
  another 
  directed 
  backwards 
  ; 
  the 
  

   elevations 
  are 
  largest 
  on 
  the 
  4th 
  abdominal 
  segment, 
  where 
  the 
  dorsal 
  

   keels 
  terminate, 
  and 
  from 
  here, 
  anteriorly, 
  as 
  posteriorly, 
  they 
  decrease 
  

   in 
  size. 
  The 
  sides 
  of 
  the 
  abdomen 
  are 
  furnished 
  with 
  four 
  rows 
  of 
  

   white 
  tubercles 
  lying 
  one 
  above 
  another 
  (one 
  tubercle 
  in 
  each 
  row 
  to 
  a 
  

   segment), 
  each 
  bearing 
  a 
  white 
  bristle 
  directed 
  backwards, 
  but 
  the 
  

   second 
  row 
  carries 
  two 
  divergent 
  bristles. 
  The 
  leg- 
  and 
  wing-cases 
  

   reach 
  to 
  the 
  posterior 
  margin 
  of 
  the 
  5th 
  abdominal 
  segment.

  the
