  Of 
  this 
  group 
  as 
  now 
  delimited 
  by 
  most 
  entomologists, 
  a 
  small 
  pro- 
  

   portion 
  is 
  aquatic, 
  constituting 
  one 
  family 
  (SiaHdae) 
  and 
  part 
  of 
  another 
  

   (Hemerobiidae). 
  Members 
  of 
  the 
  order 
  agree 
  in 
  the 
  possession 
  of 
  

   carnivorous 
  habits 
  and 
  in 
  their 
  type 
  of 
  metamorphosis, 
  and 
  in 
  little 
  else.

  Neuroptera
