  more 
  narrowly 
  at 
  the 
  apex 
  ; 
  the 
  second 
  is 
  similarly 
  

   coloured, 
  but 
  with 
  the 
  white 
  narrower 
  ; 
  the 
  third 
  and 
  

   fourth 
  have 
  the 
  sides 
  white 
  ; 
  the 
  apical 
  is 
  entirely 
  white. 
  

   All 
  the 
  segments 
  are 
  stoutly 
  longitudinally 
  striolated 
  ; 
  

   the 
  third 
  and 
  fourth 
  project 
  at 
  the 
  apex 
  into 
  stout, 
  sharp 
  

   spines, 
  and, 
  in 
  the 
  middle 
  above, 
  into 
  stouter 
  triangular 
  

   ones 
  ; 
  the 
  apical 
  segment 
  ends 
  in 
  a 
  long, 
  sharp, 
  slightly 
  

   curved 
  spine 
  ; 
  the 
  sheath 
  of 
  the 
  ovipositor 
  is 
  black 
  and 
  

   slightly 
  curved. 
  Wings

  there 
  is 
  an 
  oblique, 
  

   black 
  cloud 
  at 
  the 
  base 
  of 
  the 
  stigma 
  ; 
  the 
  apex 
  of 
  both 
  

   wings 
  smoky 
  ; 
  the

  the

   luteous. 
  

  

  Only 
  one 
  species 
  of 
  Spinaria 
  has 
  been 
  recorded 
  from 
  

   the 
  Indian 
  mainland 
  ; 
  — 
  S. 
  spinator 
  Guerin, 
  from 
  Bengal. 
  

   It 
  differs 
  from 
  the 
  species 
  here 
  described 
  in 
  the 
  thorax 
  

   being 
  entirely 
  rufous 
  ; 
  the 
  abdomen 
  pale 
  red 
  ; 
  and 
  the 
  

   hinder 
  tarsi 
  only 
  black. 
  In 
  its 
  general 
  coloration 
  our 
  

   species 
  comes 
  nearest 
  to 
  5. 
  dimidiata 
  from 
  Ceram. 
  The 
  

   genus 
  appears 
  to 
  be 
  characteristic 
  of 
  the 
  Indian 
  and 
  

   Malay 
  Islands.
