  band 
  across 
  the 
  bend

   the

  Like 
  the

  The 
  metamorphoses 
  of 
  this 
  and 
  the 
  two 
  next 
  families 
  have 
  

   been 
  summarized

  The 
  metamorphoses 
  have 
  been 
  partially 
  studied 
  by 
  myself 
  

   (^^). 
  This 
  introduced 
  species 
  has 
  now 
  spread 
  from 
  the 
  guava 
  and 
  

   coffee 
  districts 
  into 
  the 
  native 
  forests, 
  where 
  it 
  feeds 
  on 
  

   Acacia 
  koa 
  and 
  other 
  trees. 
  It 
  is 
  parasitized 
  by 
  Aphanomerus 
  

   pusillus, 
  an 
  introduced 
  egg-parasite 
  and 
  attacked 
  by 
  a 
  fungus.

  Differs 
  from 
  Delphacodes 
  and 
  allied 
  genera

  the 
  form

   the

  is

  May 
  be 
  at 
  once 
  distinguished 
  from 
  any 
  other 
  Hawaiian 
  

   asiracid 
  by 
  the 
  green 
  color 
  and 
  long 
  tegmina. 
  There 
  is 
  a 
  

   variety, 
  (rubescens), 
  found 
  with 
  it, 
  suffused 
  with 
  pinkish. 
  It 
  

   is 
  likely 
  to 
  be 
  found 
  on 
  Oahu 
  practically 
  wherever 
  Acacia 
  koa 
  

   occurs, 
  but 
  I 
  am 
  not 
  sure 
  of 
  its 
  distribution 
  on 
  the 
  other 
  islands. 
  

  

  Nymph 
  in 
  fifth 
  instar 
  is 
  green 
  (or 
  suffused 
  with 
  pink) 
  and 
  

   resembles 
  the 
  adult 
  in 
  most 
  particulars.
