  thickly 
  studded 
  with 
  circular 
  gland-pores 
  (fig. 
  5, 
  d). 
  Dorsum 
  with 
  numerous 
  spines, 
  

   especially 
  towards 
  the 
  margin. 
  Rostrum 
  relatively 
  large 
  ; 
  the 
  filaments 
  protected 
  

   by 
  a 
  very 
  long 
  membranous 
  sheath. 
  Length, 
  4*2-6*8 
  mm 
  ; 
  width, 
  4*3-5*5 
  mm. 
  

  

  Female, 
  second 
  stage. 
  Short 
  ovate 
  ; 
  dorsum 
  flat. 
  Colour 
  and 
  the 
  structural 
  

   characters 
  of 
  the 
  antennae 
  and 
  legs 
  as 
  in 
  the 
  adult 
  female. 
  Stigmatic 
  clefts 
  (fig. 
  5, 
  e) 
  

   relatively 
  deep. 
  Stigmatic 
  spines 
  two, 
  one 
  on 
  either 
  side 
  of 
  the 
  external 
  glandular 
  

   arch 
  ; 
  the 
  latter 
  much 
  more 
  extended 
  towards 
  the 
  margin, 
  and 
  with 
  fewer 
  gland- 
  

   pores 
  than 
  in 
  the 
  adult 
  ; 
  fulcrum 
  to 
  the 
  atrium 
  of 
  the 
  stigmata 
  strongly 
  produced. 
  

   Anal 
  lobes 
  (fig. 
  5,/) 
  with 
  a 
  tongue-shaped 
  sclerite 
  between 
  them 
  at 
  the 
  base. 
  

  

  Larva. 
  Ovate. 
  Antennae 
  and 
  legs 
  well 
  developed 
  ; 
  the 
  former 
  of 
  six 
  segments, 
  

   of 
  which 
  the 
  3rd 
  is 
  much 
  the 
  longest 
  and 
  equal 
  in 
  length 
  to 
  the 
  2nd, 
  4th 
  and 
  5th 
  

   together. 
  Anal 
  lobes 
  large 
  ; 
  apical 
  hair 
  very 
  long 
  and 
  stout. 
  One 
  large 
  stigmatic 
  

   spine 
  in 
  each 
  cleft. 
  Marginal 
  hairs 
  in 
  an 
  irregular 
  double 
  row. 
  Abdominal 
  segments 
  

   with 
  a 
  transverse 
  series 
  of 
  hairs, 
  slightly 
  smaller 
  than 
  those 
  at 
  the 
  margin. 
  Rostral 
  

   filaments 
  as 
  long, 
  apparently, 
  as 
  the 
  circumference 
  of 
  the 
  body. 
  

  

  Jamaica 
  : 
  on 
  the 
  banks 
  of 
  the 
  Great 
  River, 
  near 
  Montpelier 
  ; 
  attached 
  to 
  the 
  

   bark 
  of 
  an 
  unknown 
  tree 
  beneath 
  a 
  large, 
  blackish 
  coloured 
  " 
  paper 
  ' 
  nest 
  of 
  

   Cremastogaster 
  brevispinosa, 
  Mayr, 
  var. 
  tumulijera, 
  For. 
  The 
  nest 
  in 
  question 
  

   was 
  attached 
  to 
  the 
  bole 
  of 
  the 
  tree 
  about 
  six 
  feet 
  from 
  the 
  ground 
  ; 
  10.xii.1908 
  

   (R. 
  Newstead). 
  

  

  I 
  have 
  placed 
  this 
  rather 
  remarkable 
  insect 
  in 
  Cockerell's 
  genus 
  Pseudophilippia 
  

   as 
  it 
  agrees 
  best, 
  in 
  its 
  morphological 
  characters, 
  with 
  Cockerell's 
  diagnosis 
  ; 
  but 
  

   the 
  absence 
  of 
  an 
  ovisac 
  may 
  be 
  thought 
  by 
  other 
  students 
  to 
  preclude 
  its 
  admission 
  

   here. 
  It 
  seems 
  to 
  me, 
  however, 
  that 
  the 
  presence 
  of 
  a 
  glassy 
  ventral 
  scale 
  beneath 
  

   the 
  body 
  of 
  the 
  female 
  and 
  the 
  curiously 
  protected 
  stigmata 
  do 
  not 
  in 
  themselves 
  

   call 
  for 
  the 
  erection 
  of 
  a 
  new 
  genus. 
  

  

  Antonina 
  waterstoni, 
  sp. 
  nov. 
  

  

  Female, 
  adult. 
  Colour, 
  in 
  life, 
  pale 
  buff 
  to 
  dusky 
  buff. 
  Form 
  flat, 
  narrowly 
  

   ovate 
  to 
  very 
  elongate^ 
  broadly 
  rounded 
  in 
  front, 
  widest 
  generally 
  in 
  the 
  region 
  of 
  

   the 
  proximal 
  segments 
  of 
  the 
  abdomen, 
  narrowing 
  rather 
  suddenly 
  behind 
  ; 
  last 
  

   two 
  segments 
  of 
  abdomen 
  (fig. 
  6, 
  a) 
  strongly 
  constricted. 
  Antennae 
  quite 
  rudimentary 
  

   and 
  apparently 
  unsegmented 
  ; 
  they 
  are 
  placed 
  quite 
  close 
  to 
  the 
  margin. 
  Legs 
  

   absent. 
  Mentum 
  very 
  small 
  and 
  unisegmented 
  ; 
  just 
  below 
  it 
  there 
  are 
  several 
  

   minute 
  tubercles, 
  each 
  with 
  a 
  short 
  stiff 
  hair. 
  Stigmata 
  large 
  and 
  widely 
  separated 
  ; 
  

   first 
  pair 
  in 
  a 
  line 
  with 
  the 
  rostrum 
  ; 
  the 
  small 
  group 
  of 
  parastigmatic 
  glands 
  merging 
  

   into 
  those 
  at 
  the 
  margin. 
  On 
  the 
  dorsal 
  surface 
  just 
  behind 
  the 
  2nd 
  pair 
  of 
  stigmata 
  is 
  

   a 
  large 
  group 
  of 
  minute 
  spines 
  (fig. 
  6, 
  b) 
  occupying 
  the 
  whole 
  width 
  of 
  the 
  1st 
  proximal 
  

   segment 
  of 
  the 
  abdomen. 
  Margin, 
  all 
  round, 
  with 
  an 
  almost 
  continuous 
  band 
  of 
  

   relatively 
  large 
  pores 
  (fig. 
  6, 
  c) 
  and 
  a 
  few 
  minute 
  pointed 
  spines. 
  Anal 
  segment 
  

   (fig. 
  6, 
  a) 
  markedly 
  distinct 
  ; 
  dorsal 
  surface 
  with 
  a 
  pair 
  of 
  forwardly 
  directed 
  bristles 
  ; 
  

   ventrally 
  it 
  is 
  almost 
  covered 
  with 
  pores, 
  which 
  are 
  almost 
  as 
  numerous 
  as 
  those 
  

   on 
  the 
  preceding 
  segment. 
  Anal 
  lobes 
  quite 
  rudimentary, 
  each 
  bearing 
  a 
  few 
  stiff 
  

   hairs. 
  Anal 
  ring 
  (fig. 
  6> 
  a 
  1 
  ) 
  placed 
  in 
  a 
  slight 
  depression; 
  hairs 
  six 
  in 
  number, 
  and 
  

   rather 
  stout. 
  Length 
  of 
  young 
  adult, 
  3-4 
  °2 
  ; 
  width, 
  2-3*2 
  mm. 
  Old 
  adults 
  

   measure 
  : 
  length, 
  5*7-6 
  mm 
  ; 
  width, 
  3-3*2 
  mm.
