  In 
  addition 
  to 
  the 
  lack 
  of 
  the 
  occipital 
  carina, 
  all 
  the 
  species, 
  of 
  

   which 
  only 
  the 
  genotype 
  is 
  identified 
  specifically, 
  conform 
  to 
  the 
  

   following 
  description: 
  

  

  Head 
  (pi. 
  50, 
  fig. 
  12): 
  Broad 
  behind, 
  temples 
  nearly 
  reaching 
  out- 
  

   side 
  tangents 
  of 
  eyes; 
  stemmaticum 
  high 
  and 
  sharply 
  defined 
  by 
  a 
  

   surromiding 
  groove; 
  malar 
  space 
  short; 
  mandible 
  rather 
  long 
  and 
  little 
  

   narrower 
  at 
  apex 
  than 
  at 
  base; 
  clypeus 
  broadly 
  truncate. 
  

  

  Thorax: 
  Notaulices 
  rather 
  deep 
  and 
  foveolate 
  anteriorly; 
  pre- 
  

   pectoral 
  carina 
  complete; 
  scutellum 
  not 
  at 
  all 
  margined; 
  propodeum 
  

   long, 
  in 
  profile 
  with 
  a 
  gradual, 
  weakly 
  convex 
  slope. 
  Wings 
  with 
  a 
  

   hairless 
  area 
  below 
  base 
  of 
  stigma; 
  discocubitus 
  broken 
  but 
  with 
  at 
  

   most 
  a 
  veiy 
  short 
  ramelius, 
  basal 
  portion 
  nearly 
  parallel 
  to 
  basal 
  

   vein; 
  second 
  discoidal 
  cell 
  rather 
  long 
  and 
  narrow; 
  postnervulus 
  and 
  

   nervellus 
  broken 
  distinctly 
  above 
  middle. 
  

  

  Abdomen: 
  rather 
  slender.

  Australophion 
  Morley, 
  A 
  revision 
  of 
  the 
  Ichneumonidae 
  based 
  on 
  the 
  collection 
  

   in 
  the 
  British 
  Museum 
  (Natural 
  History), 
  pt. 
  1, 
  pp. 
  4, 
  30, 
  1912. 
  [Genotype: 
  

   Ophion 
  peregrinus 
  Smith.] 
  Monobasic. 
  

  

  I 
  have 
  seen 
  no 
  specimen 
  of 
  the 
  genotype, 
  but 
  there 
  appears 
  no 
  

   doubt 
  that 
  the 
  species 
  described 
  below 
  is 
  properly 
  referred 
  to 
  the 
  

   genus. 
  Despite 
  the 
  remarkable 
  inflation 
  of 
  the 
  scutellum, 
  subalar 
  

   tubercles, 
  and 
  metapleura, 
  this 
  species 
  is 
  hardly 
  more 
  than 
  subgeneri- 
  

   cally 
  distinct 
  from 
  Ophion. 
  It 
  agrees 
  with 
  all 
  the 
  key 
  characters 
  

   leading 
  to 
  Ophion.

  species 
  

  

  Male. 
  — 
  Length 
  17 
  mm., 
  antenna 
  20 
  mm. 
  

  

  Head: 
  Temples 
  strongly 
  convex 
  but 
  not 
  reaching 
  outside 
  tangents 
  

   of 
  eyes; 
  occipital 
  carina 
  complete, 
  joining 
  hypostomal 
  carina 
  far 
  above 
  

   ventral 
  articulation 
  of 
  mandible; 
  ocelli 
  not 
  touching 
  eyes, 
  stenmiaticum 
  

   only 
  moderately 
  high 
  and 
  defined 
  by 
  rather 
  weak 
  grooves; 
  face 
  very- 
  

   little 
  broader 
  than 
  frons, 
  clypeus 
  broadly 
  truncate; 
  malar 
  space 
  

   distinct 
  but 
  short; 
  mandible 
  considerably 
  narrowing 
  toward 
  apex; 
  

   antennae 
  slightly 
  longer 
  than 
  body 
  and 
  very 
  slender, 
  all 
  joints 
  much 
  

   longer 
  than 
  thick. 
  

  

  Thorax 
  (pi. 
  52, 
  fig. 
  45): 
  Polished, 
  finely 
  and 
  sparsely 
  punctate; 
  

   notaulices 
  broad 
  and 
  shallow 
  anteriorly; 
  scutellum 
  high, 
  almost 
  

   hemispherical, 
  fovea 
  deep; 
  frena 
  of 
  scutellum 
  and 
  postscutellum 
  not 
  

   at 
  all 
  foveolate; 
  prepectoral 
  carina 
  complete; 
  subalar 
  tubercle 
  and 
  

   metapleuron 
  very 
  large 
  and 
  convex; 
  propodeum 
  rather 
  short 
  and
