  Limbs 
  entirely 
  wanting. 
  Dorsum 
  with 
  numerous 
  large 
  and 
  conspicuous 
  paired 
  

   glands, 
  disposed 
  principally 
  in 
  three 
  broad 
  transverse 
  bands 
  across 
  the 
  middle 
  of 
  the 
  

   body, 
  leaving 
  the 
  anterior 
  and 
  posterior 
  areas 
  comparatively 
  free. 
  The 
  first 
  and 
  

   third 
  bands 
  divide 
  near 
  the 
  margins, 
  where 
  they 
  enclose 
  a 
  series 
  of 
  small 
  circular 
  

   glands. 
  There 
  is 
  a 
  straggling 
  group 
  of 
  the 
  large 
  paired 
  glands 
  within 
  the 
  anterior 
  

   margin; 
  a 
  short 
  marginal 
  series 
  on 
  each 
  side 
  of 
  the 
  abdomen, 
  just 
  before 
  the 
  

   constriction 
  ; 
  and 
  another 
  short 
  series, 
  on 
  each 
  side, 
  close 
  to 
  the 
  anal 
  lobes. 
  Amongst 
  

   the 
  larger 
  paired 
  glands, 
  and 
  scattered 
  over 
  other 
  parts 
  of 
  the 
  dorsum, 
  are 
  many 
  of 
  a 
  

   much 
  smaller 
  size. 
  Cribriform 
  plates 
  small, 
  each 
  with 
  a 
  broad 
  densely 
  chitinous 
  

   border 
  and 
  areola 
  te 
  centre; 
  in 
  two 
  groups 
  of 
  four, 
  immediately 
  anterior 
  to 
  the 
  

   narrowed 
  part 
  of 
  the 
  abdomen. 
  Venter 
  with 
  small 
  circular 
  glands 
  in 
  loose 
  transverse 
  

   series 
  across 
  the 
  abdominal 
  segments, 
  and 
  some 
  scattered 
  paired 
  glands 
  of 
  the 
  smaller 
  

   size.

  Although 
  the 
  single 
  

   example 
  examined 
  showed 
  no 
  waxy 
  caudal 
  filaments, 
  there 
  is 
  a 
  distinct 
  glandular 
  pit 
  

   on 
  each 
  side, 
  giving 
  rise 
  to 
  fine 
  paired 
  setae 
  such 
  as 
  usually 
  support 
  caudal 
  filaments.

  Test 
  of

  long, 
  elongate, 
  convex, 
  with 
  the 
  posterior

  produced, 
  thin,

  dull

  The 
  dorsum 
  is 
  convex, 
  with 
  a 
  wide 
  

   shallow 
  groove 
  from 
  about 
  the 
  middle 
  to 
  the 
  caudal 
  end. 
  The 
  remainder 
  of 
  the 
  test 
  

   is 
  uniformly 
  arched, 
  but 
  in 
  a 
  few 
  specimens

  appears 
  to 
  be 
  a 
  sub 
  marginal 
  series 
  

   of 
  low 
  tubercles. 
  

  

  Puparium

  Cleared

  mounted 
  the 
  adult 
  $ 
  is 
  broad 
  pear-shaped, 
  with 
  the 
  prominent 
  anal 
  

   portion 
  produced. 
  The 
  integument 
  is 
  thin 
  and 
  hyaline, 
  with 
  8-shaped 
  glands 
  

   numerous 
  but 
  scattered. 
  Those 
  of 
  the 
  marginal 
  series 
  are 
  large, 
  and 
  mostly 
  in 
  a 
  

   single 
  row, 
  but 
  at 
  the 
  sides 
  the 
  series 
  becomes 
  double 
  or 
  treble 
  for 
  a 
  short 
  distance. 
  

   The 
  8-shaped 
  glands 
  scattered 
  over 
  the 
  dorsum 
  are 
  smaller, 
  being 
  only 
  about 
  half 
  the 
  

   diameter 
  of 
  those 
  in 
  the 
  marginal 
  series. 
  The 
  rudimentary 
  antennae 
  consist 
  of 
  small 
  

   •conical 
  protuberances 
  each 
  with 
  about 
  6 
  spines 
  (fig. 
  216,

  The 
  caudal 
  lobes 
  are 
  

   prominent, 
  with 
  their 
  inner 
  faces 
  chitinised 
  and 
  the 
  spines 
  strongly 
  developed 
  (fig.
