  Neuroptera. 
  

  

  Mr. 
  Newman 
  has 
  commenced 
  in 
  the 
  ' 
  Zoologist 
  ' 
  for 
  October, 
  1852, 
  an 
  article 
  en- 
  

   titled 
  " 
  Proposed 
  Division 
  of 
  Neuroptera 
  into 
  two 
  Classes 
  '' 
  [orders], 
  from 
  the 
  charac- 
  

   ter 
  of 
  their 
  metamorphosis 
  ; 
  to 
  which 
  (instead 
  of 
  giving 
  new 
  classical 
  names) 
  he 
  has 
  

   applied 
  the 
  names 
  of 
  Neuroptera, 
  Linn., 
  and 
  Stegoptera, 
  Dum., 
  in 
  senses 
  different 
  

   from 
  those 
  of 
  their 
  original 
  proposers. 
  The 
  proposal 
  of 
  an 
  eighth 
  class 
  [order] 
  at 
  once 
  

   overthrows 
  the 
  septenary 
  system 
  : 
  whilst 
  it 
  is 
  equally 
  evident 
  that 
  the 
  formula 
  of 
  the 
  

   primary 
  divisions 
  of 
  the 
  Insecta 
  Tetraptera 
  given 
  by 
  the 
  author, 
  is 
  at 
  variance 
  with 
  his 
  

   opening 
  paragraphs, 
  since 
  his 
  Neuroptera 
  ought 
  to 
  enter 
  into 
  the 
  Isomorphous 
  divi- 
  

   sion, 
  and 
  the 
  Stegoptera 
  into 
  the 
  Necromorphous. 
  Of 
  the 
  characters 
  given 
  of 
  these 
  

   two 
  classes, 
  the 
  only 
  one 
  distinctive 
  of 
  the 
  larvae 
  is 
  untenable, 
  whilst 
  that 
  of 
  the 
  want 
  

   of 
  a 
  mouth 
  in 
  the 
  pupa 
  of 
  the 
  Stegoptera 
  is 
  also 
  incorrect, 
  the 
  pupa 
  of 
  Myrmeleon 
  

   having 
  a 
  mouth 
  quite 
  unlike 
  that 
  of 
  the 
  larva 
  or 
  imago; 
  and 
  the 
  pupae 
  of 
  Eaphidia 
  

   and 
  Phryganea 
  are 
  active 
  before 
  assuming 
  the 
  imago 
  state.* 
  Neither 
  is 
  the 
  presence 
  

   of 
  a 
  cocoon 
  constant 
  in 
  the 
  Stegoptera. 
  Again, 
  with 
  reference 
  to 
  the 
  characters 
  of 
  the 
  

   imago 
  : 
  Perla, 
  Termes, 
  and 
  Thrips 
  have 
  decumbent 
  wings, 
  and 
  Psocus 
  has 
  roof-life 
  

   wings. 
  Power 
  of 
  flight 
  is 
  denied 
  to 
  Thrips, 
  and 
  the 
  heavily 
  flying 
  Perla 
  is 
  ranked 
  

   next 
  to 
  Libellula. 
  In 
  the 
  family 
  characters 
  of 
  the 
  Agrionidse 
  derived 
  from 
  the 
  larvae, 
  

   Mr, 
  Newman 
  has 
  erred 
  in 
  respect 
  to 
  one 
  of 
  the 
  most 
  important, 
  describing 
  the 
  breath- 
  

   ing-apparatus 
  as 
  internal, 
  whereas 
  in 
  Agrion 
  the 
  branchiae 
  are 
  external 
  and 
  caudal 
  ; 
  

   and 
  he 
  has 
  omitted 
  one 
  equally 
  important, 
  namely, 
  the 
  possession 
  of 
  ocelli, 
  which 
  are 
  

   wanting 
  in 
  the 
  larvaj 
  of 
  the 
  Libellulidaj. 
  Lastly, 
  in 
  order 
  to 
  make 
  each 
  of 
  these 
  two 
  

   classes 
  consist 
  of 
  seven 
  divisions, 
  Agrion 
  is 
  raised 
  to 
  the 
  same 
  rank 
  as 
  Ephemera, 
  

   Perla, 
  and 
  Termes; 
  and 
  Thrips, 
  with 
  its 
  veinless 
  wings, 
  is 
  now 
  for 
  the 
  first 
  time 
  added 
  

   to 
  the 
  Neuroptera 
  : 
  whilst 
  Phryganea 
  is 
  added 
  to 
  the 
  Stegoptera. 
  With 
  the 
  exception 
  

   of 
  these 
  two 
  additions, 
  the 
  propriety 
  of 
  which 
  seems 
  to 
  me 
  very 
  questionable, 
  the 
  two 
  

   divisions 
  are 
  identical 
  with 
  my 
  two 
  sections, 
  Biomorphotica 
  and 
  Necromorphotica. 
  — 
  

   (Gen. 
  Synops. 
  p. 
  46). 
  The 
  exceptional 
  characters 
  alluded 
  to 
  above, 
  are, 
  however, 
  in 
  

   my 
  opinion, 
  sufficiently 
  important 
  to 
  show 
  the 
  impropriety 
  of 
  raising 
  these 
  two 
  sec- 
  

   tions 
  to 
  the 
  rank 
  of 
  orders, 
  such 
  as 
  Hymenoptera, 
  Coleoptera, 
  or 
  Lepidoptera. 
  

  

  The 
  first 
  part 
  of 
  the 
  Catalogue 
  of 
  the 
  species 
  of 
  Neuroptera 
  contained 
  in 
  the 
  

   Collection 
  of 
  the 
  British 
  Museum, 
  by 
  Mr. 
  F. 
  Walker, 
  has 
  been 
  published, 
  containing 
  

   the 
  Phryganeidae 
  and 
  Perlidae.f 
  

  

  * 
  It 
  is 
  equally 
  incorrect 
  to 
  assert 
  that 
  the 
  motion 
  of 
  these 
  pupae 
  is 
  similar 
  to 
  that 
  

   of 
  ^geria 
  or 
  Hepialus 
  : 
  movement 
  in 
  these 
  is 
  confined 
  simply 
  to 
  a 
  wriggling 
  of 
  the 
  

   abdominal 
  segments 
  ; 
  in 
  the 
  former, 
  the 
  antennae, 
  legs, 
  and 
  mouth-organs 
  are 
  en- 
  

   dowed 
  with 
  powers 
  of 
  motion. 
  

  

  t 
  Acentropus 
  niveus, 
  although 
  aflirmed 
  to 
  be 
  Lepidopterous, 
  is 
  admitted 
  into 
  this 
  

   catalogue, 
  being 
  rejected 
  by 
  the 
  Micro-Lepidopterists.
