  Ilyalopeplus 
  pellucidus 
  (Stal) 
  

  

  Although 
  only 
  known 
  so 
  far 
  from 
  the 
  Hawaiian 
  Isles, 
  this 
  

   species 
  is 
  hardly 
  an 
  endemic 
  form, 
  and 
  may 
  be 
  looked 
  for 
  in 
  

   Australia 
  or 
  one 
  of 
  the 
  Southern 
  Isles. 
  It 
  is 
  principally 
  

   attaclied 
  to 
  Hibiscus 
  rosasinensis, 
  at 
  least 
  in 
  the 
  Lowlands. 
  

  

  The 
  ultimate 
  nymph 
  is 
  pale 
  translucent 
  greenish; 
  the 
  vertex 
  

   has 
  three 
  purplish-red 
  or 
  sanguineous 
  percurrent 
  lines, 
  (the 
  

   outer 
  ones 
  sinuate) 
  rui:ining 
  obscurely 
  onto 
  the 
  pronotum, 
  

   there 
  is 
  also 
  a 
  lateral 
  percurrent 
  line 
  on 
  the 
  gula. 
  The 
  anten- 
  

   nae 
  have 
  the 
  apical 
  third 
  of 
  the 
  second, 
  third 
  and 
  fourth 
  seg- 
  

   ments 
  purplish-red 
  (or 
  pinkish 
  or 
  blood-red) 
  and 
  the 
  rest 
  

   is 
  speckled 
  with 
  the 
  same; 
  the 
  form 
  is 
  as 
  in 
  the 
  adult. 
  La- 
  

   bium 
  with 
  the 
  apex 
  dark 
  fuscous. 
  The 
  head 
  and 
  antennae 
  

   have 
  black 
  and 
  yellow 
  pilosity 
  mixed, 
  the 
  nota 
  and 
  ter- 
  

   gites 
  have 
  short 
  black 
  bristly 
  hairs. 
  Beneath 
  there 
  are 
  

   golden 
  yellow 
  hairs. 
  The 
  hind 
  femora 
  and 
  tibiae 
  are 
  

   sparsely 
  speckled 
  with 
  red. 
  The 
  head 
  is 
  shaped 
  much 
  

   as 
  in 
  the 
  adult, 
  being 
  about 
  one-half 
  wider 
  than 
  long, 
  

   the 
  vertex 
  is 
  wider 
  than 
  the 
  eyes 
  together. 
  The 
  second 
  

   segment 
  of 
  the 
  antennae 
  is 
  three 
  times 
  as 
  long 
  as 
  the 
  first 
  and 
  

   nearly 
  twice 
  as 
  long 
  as 
  the 
  third, 
  also 
  twice 
  and 
  two-thirds 
  as 
  

   long 
  as 
  the 
  fourth. 
  The 
  labium 
  reaches 
  to 
  the 
  middle 
  of 
  the 
  hind 
  

   coj.ie, 
  the 
  tirst 
  segment 
  being 
  one-third 
  longer 
  than 
  the 
  second 
  

   and 
  twice 
  as 
  long 
  as 
  the 
  third, 
  second 
  and 
  fourth 
  subsequal. 
  The 
  

   pronotum 
  is 
  a 
  little 
  longer 
  than 
  the 
  head, 
  and 
  a 
  little 
  less 
  long 
  

   than 
  its 
  apical 
  width, 
  the 
  hind 
  margin 
  is 
  about 
  two-thirds 
  wider 
  

   than 
  the 
  apical 
  margin. 
  The 
  scutellum 
  is 
  rounded 
  behind. 
  There 
  

   is 
  one 
  odoriferous 
  orifice 
  on 
  the 
  basal 
  margin 
  of 
  the 
  fourth 
  

   tergite. 
  The 
  xyphus 
  is 
  angularly 
  rounded 
  behind, 
  the 
  coxae 
  

   are 
  subcontiguous. 
  

  

  Penultimate 
  stage 
  is 
  very 
  similar 
  to 
  the 
  last, 
  but 
  of 
  

   course 
  the 
  tegmina 
  are 
  less 
  developed. 
  The 
  labium 
  

   reaches 
  nearly 
  to 
  the 
  apical 
  margin 
  of 
  the 
  2nd 
  sternite, 
  but 
  

   the 
  actual 
  length 
  is 
  the 
  same 
  as 
  in 
  the 
  last 
  instar, 
  as 
  also 
  the 
  

   proportions, 
  and 
  it 
  is 
  the 
  body 
  which 
  is 
  shorter. 
  The 
  antennal 
  

   proportions 
  are 
  practically 
  as 
  in 
  the 
  ultimate 
  instar 
  ; 
  the 
  hind 
  

   margin 
  of 
  the 
  pronotum 
  is 
  scarcely 
  wider 
  than 
  the 
  apical, 
  and 
  

   is 
  nearly 
  one-half 
  wider 
  than 
  its 
  median 
  length.
