  green, 
  the 
  dorsum 
  more 
  or 
  less 
  mottled 
  with 
  reddish 
  brown. 
  Dried 
  insect 
  uniform 
  

   reddish 
  brown. 
  Rostrum 
  conspicuous, 
  pyriform, 
  approximately 
  central. 
  Antennae 
  

   submarginal, 
  rudimentary, 
  consisting 
  of 
  an 
  irregular 
  tubercle 
  surmounted 
  by 
  two 
  

   longish 
  stout 
  bristles 
  and 
  one 
  short 
  spiniform 
  hair. 
  Spiracles 
  conspicuous, 
  

   subglobular, 
  at 
  a 
  considerable 
  distance 
  from 
  margin, 
  with 
  scattered 
  series 
  of 
  minute 
  

   pores 
  connecting 
  them 
  with 
  the 
  margin. 
  Abdominal 
  extremity 
  slightly 
  cleft 
  ; 
  anal 
  

   tubercles 
  broad 
  and 
  stout, 
  but 
  not 
  very 
  prominent, 
  each 
  with 
  a 
  long 
  seta 
  at 
  its 
  

   apex 
  and 
  one 
  or 
  two 
  short 
  stout 
  spines 
  near 
  the 
  base. 
  Anal 
  ring 
  stout, 
  with 
  six 
  

   stout 
  hairs 
  which 
  just 
  project 
  beyond 
  the 
  margin. 
  Margin 
  with 
  a 
  continuous 
  

   series 
  of 
  large 
  approximately 
  circular 
  thick-rimmed 
  pores, 
  in 
  pairs, 
  and 
  a 
  double 
  

   ventro-marginal 
  series 
  of 
  minute 
  pores. 
  There 
  are 
  some 
  scattered 
  paired 
  pores 
  of 
  

   a 
  slightly 
  larger 
  size 
  on 
  the 
  dorsum, 
  and 
  many 
  simple 
  circular 
  pores 
  on 
  the 
  ventral 
  

   surface 
  of 
  the 
  abdomen. 
  Length 
  of 
  extended 
  insect 
  1*25 
  to 
  1*75 
  mm. 
  Breadth 
  

   0*80 
  to 
  1'25 
  mm. 
  After 
  oviposition 
  the 
  insect 
  becomes 
  greatly 
  shrunken 
  and 
  does 
  

   not 
  resume 
  its 
  original 
  proportions 
  during 
  maceration. 
  

  

  " 
  Early 
  adult 
  female 
  at 
  first 
  pinkish, 
  later 
  dull 
  green, 
  finely 
  maculated 
  with 
  reddish 
  

   brown. 
  The 
  outermost 
  series 
  of 
  the 
  fringe 
  is 
  at 
  first 
  the 
  shorter, 
  but 
  soon 
  outgrows 
  

   the 
  nymphal 
  fringe. 
  Traces 
  of 
  the 
  larval 
  fringe 
  can 
  often 
  be 
  distinguished 
  at 
  intervals 
  

   within 
  the 
  margin. 
  

  

  " 
  In 
  the 
  nymphal 
  stage 
  the 
  fringe 
  is 
  in 
  a 
  single 
  series, 
  but 
  within 
  the 
  margin 
  are 
  

   remains 
  of 
  the 
  divaricating 
  filaments 
  of 
  the 
  later 
  larval 
  stage. 
  

  

  " 
  The 
  newly 
  hatched 
  larva 
  is 
  of 
  an 
  oblong 
  oval 
  form, 
  very 
  pale 
  pinkish 
  or 
  reddish 
  

   brown. 
  Limbs 
  well 
  developed. 
  Antennae 
  six- 
  jointed, 
  the 
  sixth 
  much 
  the 
  longest, 
  

   with 
  truncate 
  apex. 
  Margin 
  with 
  fourteen 
  8-shaped 
  spinnerets 
  on 
  each 
  side, 
  and 
  a 
  

   median 
  dorsal 
  pair 
  of 
  similar 
  pores 
  immediately 
  above 
  the 
  rostrum. 
  Length 
  0*2 
  mm. 
  

  

  " 
  The 
  larva 
  subsequently 
  secretes 
  a 
  fringe 
  of 
  short 
  glassy 
  filaments 
  which 
  are 
  paired 
  

   and 
  diverging 
  on 
  the 
  cephalo-thoracic 
  area, 
  but 
  single 
  on 
  the 
  abdominal 
  margin 
  

   (although 
  the 
  spinnerets 
  giving 
  rise 
  to 
  these 
  latter 
  are 
  of 
  the 
  same 
  form 
  as 
  the 
  others). 
  

  

  " 
  Ova 
  very 
  pale 
  pinkish 
  or 
  yellowish. 
  

  

  " 
  Male 
  unknown. 
  A 
  single 
  example 
  was 
  observed, 
  in 
  which 
  the 
  dorsum 
  was 
  

   distinctly 
  tricarinate 
  and 
  bore 
  a 
  marginal 
  and 
  three 
  dorsal 
  series 
  of 
  curling 
  filaments. 
  

   This 
  may 
  possibly 
  be 
  the 
  male 
  puparium."

  caudal 
  extremity 
  and 
  part 
  of 
  the 
  marginal 
  series 
  of 
  figure-8 
  glands 
  of 
  the 
  adult 
  

   female 
  are

  " 
  The

  the

  of

  with 
  a

  of 
  a 
  

   yellowish
