  nature 
  of 
  the 
  different

   do 
  not 
  undergo 
  any 
  subsequent 
  change.

  t 
  From 
  information 
  recently 
  received 
  from 
  Dr. 
  Schaum, 
  I 
  am 
  able 
  to 
  state 
  that 
  

   the 
  remarkable 
  larva 
  figured 
  in 
  my 
  ' 
  Introduction,' 
  ii. 
  fig. 
  66, 
  1, 
  and 
  described 
  by 
  Roux 
  

   under 
  the 
  name 
  of 
  Necrophilus 
  arenarius, 
  referred 
  to 
  by 
  H. 
  Brauer, 
  is 
  the 
  real 
  larva 
  

   of 
  Nemopteryx, 
  as 
  I 
  had 
  suggested 
  was 
  probably 
  the 
  case. 
  By 
  an 
  unfortunate 
  typo- 
  

   graphical 
  error, 
  this 
  name 
  is 
  printed 
  throughout 
  Herr 
  Brauer's 
  paper 
  as 
  Neuroptera.
