  Microlepidoptera. 
  

  

  very 
  dark 
  brown, 
  inserted 
  deeply 
  into 
  the 
  next 
  segment, 
  through 
  

   which 
  it 
  is 
  visible 
  in 
  the 
  form 
  of 
  two 
  rounded 
  lobes 
  ; 
  on 
  this 
  second 
  

   segment, 
  posteriorly, 
  are 
  four 
  brown 
  spots, 
  two 
  on 
  each 
  side 
  of 
  a 
  

   central 
  whitish 
  line, 
  which 
  extends 
  hence 
  down 
  the 
  other 
  segments 
  ; 
  

   anal 
  segment 
  with 
  a 
  small 
  faint 
  brownish 
  mark 
  ; 
  low 
  down 
  on 
  the 
  

   side 
  are 
  two 
  dark 
  lines 
  along 
  the 
  whole 
  length. 
  On 
  the 
  upper 
  

   surface 
  are 
  some 
  faint 
  indistinct 
  depressions. 
  

  

  Six 
  pectoral 
  legs 
  black, 
  eight 
  ventral 
  and 
  two 
  anal 
  legs 
  the 
  colour 
  

   of 
  the 
  body. 
  

  

  Feeds 
  in 
  the 
  leaves 
  of 
  Dactrjlus 
  glomeratus, 
  hollowing 
  out 
  the 
  

   entire 
  extremity, 
  which 
  thus 
  becomes 
  bleached 
  (fig. 
  3h). 
  

  

  Found 
  by 
  myself 
  near 
  Mickleham 
  on 
  17th 
  April, 
  and 
  by 
  

   Mr. 
  Stainton 
  and 
  Mr. 
  Wing 
  on 
  the 
  Croydon 
  tram-road 
  on 
  12th 
  

   May. 
  

  

  Pupa 
  (fig. 
  3 
  c). 
  Length 
  Q\ 
  lines. 
  Whitish 
  brown, 
  curved, 
  ro- 
  

   bust 
  and 
  obtuse 
  in 
  front, 
  the 
  back 
  elevated 
  into 
  a 
  strong 
  ridge, 
  at 
  

   the 
  base 
  of 
  which 
  on 
  each 
  side 
  is 
  a 
  similar 
  but 
  smaller 
  lateral 
  

   projection, 
  the 
  furrow 
  between 
  occupied 
  by 
  a 
  dark 
  brown 
  line. 
  

   The 
  wing 
  cases 
  are 
  marked 
  with 
  a 
  curved 
  brown 
  line. 
  These 
  

   markings 
  are 
  all 
  visible 
  on 
  the 
  pupa-skin 
  after 
  the 
  imago 
  has 
  

   emerged. 
  There 
  is 
  no 
  thread 
  thrown 
  across 
  the 
  body 
  as 
  in 
  the 
  

   two 
  preceding 
  species 
  ; 
  it 
  is 
  held 
  in 
  situ 
  upon 
  a 
  slight 
  carpeting 
  

   of 
  silk 
  by 
  the 
  attachment 
  thereto 
  of 
  the 
  anal 
  segment 
  by 
  silken 
  

   threads, 
  aided 
  probably 
  by 
  some 
  very 
  short 
  stout 
  hairs 
  which 
  pro- 
  

   ject 
  from 
  the 
  underside 
  of 
  the 
  rounded 
  anal 
  segment. 
  

  

  Imago 
  (fig. 
  3, 
  $ 
  and 
  ?). 
  Not 
  an 
  uncommon 
  species 
  among 
  

   grass 
  in 
  many 
  places 
  in 
  June. 
  

  

  Note. 
  — 
  It 
  will 
  be 
  observed 
  that 
  the 
  figures 
  of 
  the 
  perfect 
  insects, 
  

   as 
  well 
  as 
  the 
  preparatory 
  states, 
  are 
  highly 
  magnified, 
  although 
  

   the 
  usual 
  indication 
  of 
  the 
  expansion 
  of 
  the 
  former 
  has 
  been 
  acci- 
  

   dentally 
  omitted 
  on 
  the 
  plates.
