  widened, 
  the 
  others 
  gradually 
  taperhig 
  to 
  the 
  extremity 
  of 
  the 
  

   body. 
  Six 
  pectoral, 
  six 
  ventral, 
  and 
  two 
  anal 
  legs 
  the 
  colour 
  of 
  

   the 
  body. 
  

  

  Feeds 
  in 
  the 
  radical 
  leaves 
  of 
  ScaUosa 
  Columbaria 
  (PI. 
  XIII. 
  

   fig. 
  2 
  h), 
  mining 
  on 
  the 
  underside, 
  detaching 
  the 
  epidermis, 
  which 
  

   becomes 
  wrinkled 
  in 
  longitudinal 
  folds 
  ; 
  the 
  upper 
  surface 
  becomes 
  

   convex 
  in 
  consequence, 
  but 
  preserves 
  its 
  colour. 
  

  

  Fupa 
  light 
  brown, 
  with 
  a 
  few 
  very 
  fine 
  hairs, 
  and 
  a 
  stout 
  anal 
  

   spine. 
  

  

  There 
  are 
  two 
  broods 
  in 
  a 
  year. 
  I 
  first 
  found 
  the 
  larvae, 
  very 
  

   small, 
  on 
  the 
  9th 
  of 
  x\pril, 
  1852, 
  at 
  the 
  side 
  of 
  the 
  old 
  tram-way 
  

   beyond 
  Croydon, 
  and 
  they 
  were 
  perfected 
  at 
  the 
  end 
  of 
  May. 
  

   The 
  second 
  brood 
  of 
  caterpillars 
  appeared 
  in 
  July, 
  and 
  the 
  moths 
  

   in 
  August. 
  

  

  This 
  is 
  the 
  only 
  species 
  of 
  this 
  genus 
  whose 
  larvae 
  are 
  known 
  to 
  

   feed 
  upon 
  a 
  herbaceous 
  plant, 
  all 
  the 
  others 
  being 
  found 
  on 
  the 
  

   leaves 
  of 
  trees 
  and 
  shrubs.

  Ent.

   Larva 
  (PI. 
  XIII. 
  fig. 
  3 
  a). 
  — 
  Length 
  3 
  lines. 
  — 
  Greenish 
  white, 
  

   widest 
  in 
  the 
  centre, 
  tapering 
  a 
  little 
  to 
  each 
  end 
  ; 
  thus 
  differing 
  

   from 
  all 
  other 
  known 
  larvae 
  of 
  this 
  genus, 
  inasmuch 
  as 
  in 
  them 
  

   the 
  thoracic 
  segments 
  are 
  widest. 
  Herr 
  v. 
  Nicelli 
  has 
  noticed 
  this 
  

   peculiarity 
  in 
  his 
  paper 
  on 
  Lithocolletis, 
  in 
  the 
  " 
  Entomologische 
  

   Zeitung," 
  for 
  1851 
  (translated 
  by 
  Mr. 
  Stainton, 
  Zoologist, 
  App. 
  

   clxiii). 
  Head 
  pale 
  greenish, 
  margins 
  and 
  mouth 
  brown. 
  Six 
  

   pectoral, 
  six 
  ventral, 
  and 
  two 
  anal 
  legs, 
  the 
  colour 
  of 
  the 
  body. 
  

   Mines 
  the 
  underside 
  of 
  the 
  leaves 
  of 
  honeysuckle 
  (Lonicera 
  

   periclyinenum), 
  making 
  a 
  large 
  cavity 
  (PI. 
  XIII. 
  fig. 
  3 
  c), 
  in 
  con- 
  

   sequence 
  of 
  which 
  a 
  large 
  fold 
  downward 
  of 
  the 
  leaf 
  occurs, 
  and 
  

   the 
  cuticle 
  appears 
  white 
  on 
  the 
  upper 
  side, 
  but 
  tlie 
  leaf 
  does 
  not 
  

   twist 
  round 
  at 
  right 
  angles, 
  as 
  in 
  the 
  case 
  of 
  L. 
  trifasciella. 
  Found 
  

   in 
  July 
  and 
  September. 
  

  

  Pupa 
  (PI. 
  XIII. 
  fig. 
  3 
  b). 
  — 
  Light 
  brown, 
  robust 
  ; 
  obtuse 
  at 
  the 
  

   head 
  and 
  tapering 
  to 
  the 
  other 
  end, 
  on 
  which 
  is 
  no 
  spine, 
  but 
  a 
  

   scarcely 
  visible 
  blunt 
  prolongation. 
  There 
  area 
  few 
  hairs 
  along 
  

   the 
  whole 
  extent, 
  and 
  projecting 
  from 
  under 
  the 
  head 
  towards 
  

   the 
  side, 
  apparently 
  from 
  the 
  margin 
  of 
  the 
  next 
  segment, 
  are 
  

   two 
  stout 
  hairs, 
  or 
  spines, 
  curving 
  outwards. 
  The 
  covers 
  of 
  the 
  

   antennae 
  are 
  longer 
  than 
  the 
  wing 
  cases, 
  but 
  the 
  pair 
  of 
  hind 
  legs 
  

   along 
  which 
  they 
  are 
  laid 
  are 
  still 
  a 
  little 
  longer, 
  and 
  all 
  are 
  joined 
  

   together 
  in 
  one 
  piece, 
  which 
  at 
  the 
  apex 
  is 
  free 
  from 
  the 
  body.
