  The

  This 
  

   species 
  has 
  not 
  otherwise 
  been 
  recoirnized 
  since 
  its 
  description 
  in 
  1829, 
  

   and 
  the 
  correctness 
  of 
  the 
  identification 
  of 
  Gray's

  is 
  ex- 
  

   tremely 
  doubtful. 
  Townes, 
  in 
  1938,* 
  synonymized 
  Paniscus 
  Schrank 
  

   with 
  Ophion 
  and 
  used 
  A^etilia 
  Gray 
  for 
  Paniscns 
  of 
  authors. 
  Although 
  

   1 
  fi'cl 
  that 
  this 
  action 
  was 
  too 
  precipitate 
  and 
  will 
  perhaps 
  not 
  receive 
  

   the 
  support 
  and 
  following 
  of 
  a 
  majority 
  of 
  the 
  contemporary 
  specialists 
  

   on 
  the 
  Ichneumonidae, 
  his 
  action 
  seems 
  to 
  have 
  blocked 
  the 
  preserva- 
  

   tion 
  of 
  Paniscus 
  in 
  the 
  sense 
  sanctioned 
  by 
  well 
  over 
  a 
  hundred 
  years 
  

   of 
  usage, 
  and 
  I 
  shall 
  follow 
  him 
  in 
  the 
  use 
  of 
  Netelia. 
  There 
  is, 
  

   however, 
  still 
  the 
  threat 
  of 
  instability 
  in 
  the 
  nomenclature 
  of 
  the 
  genus 
  

   if 
  the 
  type 
  of 
  Paniscus 
  inquinatus 
  Gravenhoj'st 
  is 
  still 
  in 
  existence, 
  

   for 
  there 
  is 
  no 
  assurance 
  that 
  examination 
  of 
  the 
  type 
  will 
  show 
  it 
  to 
  

   be 
  congeneric 
  with 
  the 
  species 
  now 
  to 
  be 
  known 
  as 
  Netelia, 
  especially 
  

   those 
  of 
  the 
  subgenus 
  Netelia 
  as 
  identified 
  by 
  Townes. 
  

  

  Ophion 
  is 
  a 
  genus 
  of 
  world-wide 
  distribution 
  and 
  contains 
  many 
  

   hundreds 
  of 
  species 
  differing 
  widely 
  among 
  themselves 
  but 
  each 
  

   possessing 
  virtually 
  all 
  the 
  characters 
  in 
  the 
  foregoing 
  key 
  that 
  apply 
  

   to 
  the 
  Ophion 
  group 
  of 
  genera. 
  In 
  this 
  somewhat 
  heterogeneous 
  

   assemblage 
  are 
  included 
  a 
  number 
  of 
  groups 
  of 
  sj)ecies 
  which 
  are 
  more 
  

   or 
  less 
  well 
  distinguished 
  from 
  the 
  general 
  mass 
  of 
  more 
  typical 
  forms 
  

   but 
  are 
  not, 
  I 
  think, 
  generically 
  distinct. 
  Such 
  species 
  as 
  bifoveolatus 
  

   Brulld, 
  colnradensis 
  (Felt), 
  slossonae 
  Davis, 
  and 
  others 
  in 
  the 
  North 
  

   American 
  fauna 
  are 
  representatives 
  of 
  such 
  groups, 
  and 
  one 
  is 
  perhaps 
  

   justified 
  in 
  suspecting 
  that 
  some 
  of 
  the 
  generic 
  names 
  that 
  have 
  been 
  

   proposed 
  apply 
  to 
  such 
  groups. 
  It 
  may 
  be 
  possible 
  and 
  advisal)le 
  to 
  

   employ 
  some 
  of 
  these 
  names, 
  and 
  others 
  not 
  yet 
  proposed, 
  in 
  the 
  

   subgeneric 
  sense. 
  

  

  The 
  synonymy 
  of 
  Neophion 
  Morley 
  is 
  on 
  the 
  authority 
  of 
  J. 
  F. 
  

   Perkins, 
  who 
  examined 
  the 
  tyi)e 
  of 
  A'^. 
  crassus 
  Morley 
  and 
  pronounced 
  

   it 
  a 
  species 
  of 
  Ophion. 
  

  

  The 
  genus 
  is 
  characterized 
  as 
  follows: 
  

  

  Head 
  (pi. 
  50, 
  fig. 
  21): 
  Various 
  in 
  form, 
  but 
  ahva^'s 
  with 
  trophi 
  

   normal, 
  with 
  none 
  of 
  the 
  elements 
  greatly 
  elongate; 
  mandible 
  gradually 
  

   narrowed 
  from 
  base 
  to 
  apex 
  and 
  not 
  conspicuously 
  twisted, 
  teeth 
  

   equal 
  or 
  lower 
  tooth 
  the 
  longer; 
  clypeus 
  truncate 
  or 
  broadly 
  arcuate 
  

   at 
  apex; 
  occipital 
  carina 
  distinct. 
  

  

  Thorax: 
  Pronotal 
  sinus 
  (i)l. 
  /jo, 
  fig. 
  73) 
  broad, 
  exposing 
  spirncular 
  

   sclcrite; 
  notaulices 
  more 
  or 
  less 
  distinct 
  at 
  least 
  anteriorly; 
  meso- 
  

   pleuron 
  with 
  speculum 
  distinct; 
  prcpectoral 
  carina 
  (pi. 
  52, 
  fig. 
  41)
