  HETEROPHAGA. 
  

  

  The 
  species 
  of 
  this 
  series 
  vary 
  greatly 
  in 
  their 
  habits 
  and 
  appearance, 
  

   but 
  none 
  of 
  them 
  have 
  the 
  abdomen 
  sessile 
  or 
  united 
  for 
  its 
  full 
  width 
  to 
  

   the 
  thorax, 
  and 
  none 
  of 
  them 
  feed 
  openly 
  upon 
  vegetation 
  by 
  devouring 
  

   plant 
  tissue. 
  There 
  are 
  collectors 
  of 
  plant 
  products, 
  like 
  honey 
  and 
  

   pollen, 
  and 
  some 
  feeders 
  in 
  stems 
  and 
  seeds, 
  but 
  the 
  latter 
  habit 
  is 
  rather 
  

   exceptional. 
  

  

  Super-family 
  ICHNEUMONOIDEA. 
  

  

  Contains 
  moderate 
  sized 
  species 
  on 
  the 
  whole, 
  the 
  wings 
  with 
  a 
  well- 
  

   arranged 
  series 
  of 
  veins, 
  antennse 
  not 
  elbowed, 
  ovipositor 
  attached 
  before 
  

   the 
  end 
  of 
  the 
  abdomen 
  and 
  sometimes 
  very 
  long. 
  As 
  a 
  whole, 
  parasitic 
  

   on 
  other 
  insects. 
  

  

  In 
  this 
  and 
  the 
  other 
  series 
  of 
  parasitic 
  forms 
  the 
  actual 
  records 
  are 
  

   not 
  always 
  as 
  full 
  and 
  satisfactory 
  as 
  they 
  might 
  be. 
  Many 
  species 
  are 
  

   never 
  obtained 
  unless 
  actually 
  bred 
  from 
  their 
  hosts, 
  and 
  by 
  no 
  means 
  

   all 
  the 
  host 
  species 
  in 
  New 
  Jersey 
  have 
  been 
  bred. 
  It 
  has 
  been 
  deemed 
  

   advisable, 
  therefore, 
  to 
  include 
  those 
  species 
  of 
  wide 
  distribution 
  bred 
  

   from 
  host 
  insects 
  which 
  are 
  actually 
  known 
  to 
  occur 
  with 
  us. 
  The 
  rule 
  

   is 
  that 
  a 
  native 
  parasite 
  has 
  the 
  same 
  distribution 
  as 
  its 
  host, 
  and, 
  while 
  

   there 
  are 
  many 
  exceptions 
  to 
  this, 
  they 
  will 
  hardly 
  be 
  among 
  such 
  species 
  

   as 
  are 
  included 
  here.
