  The 
  species 
  of 
  Oechalia 
  are 
  carnivorous, 
  preying 
  on 
  cater- 
  

   pillars 
  of 
  Omiodes 
  accepta, 
  Scotorythra 
  rara, 
  etc., 
  though 
  they 
  

   do 
  not 
  always 
  disdain 
  vegetal 
  juices, 
  at 
  least 
  in 
  captivity. 
  They 
  

   lurk 
  principally 
  in 
  Filices, 
  or 
  in 
  Kukui 
  (Aleurites 
  triloba), 
  

   and 
  when 
  captured, 
  usually 
  feign 
  death. 
  

  

  In 
  attacking 
  a 
  small 
  larva 
  of 
  Hymenia 
  recurvalis 
  in 
  captivity 
  

   a 
  nymph 
  of 
  Oechalia 
  inserted 
  its 
  stylets 
  in 
  one 
  of 
  the 
  clasping 
  

   legs 
  and 
  maintained 
  its 
  hold, 
  — 
  despite 
  the 
  larva's 
  struggles 
  — 
  

   without 
  at 
  all 
  employing 
  its 
  fore

  A 
  popular 
  error 
  among 
  Entomologists 
  is 
  to 
  suppose 
  that 
  the 
  

   labium 
  (rostrum) 
  acts 
  as 
  a 
  piercing 
  instrument. 
  In 
  sut'h 
  bugs 
  as 
  Oechalia, 
  

   the 
  labium 
  is 
  directed 
  to 
  the 
  supposed 
  prey, 
  and 
  its 
  suitability 
  is 
  ascer- 
  

   tained 
  by 
  the 
  sensory 
  hairs 
  at 
  the 
  apex, 
  then 
  the 
  stylets 
  pierce 
  the 
  skin 
  

   and 
  the 
  labium 
  is 
  applied 
  to 
  the 
  orifice 
  thus 
  make, 
  possibly 
  entering 
  a 
  

   little 
  as 
  it 
  becomes 
  enlarged.
