  sclerotizatii)n 
  of 
  the 
  canlo; 
  tho 
  niaiulihlos 
  arc 
  very 
  stout 
  and 
  overlap 
  

   across 
  tlie 
  median 
  line. 
  

  

  The 
  anomaline 
  larva 
  (pi. 
  49, 
  fig. 
  4) 
  is, 
  in 
  some 
  respects, 
  more 
  or 
  less 
  

   intermediate 
  between 
  those 
  of 
  the 
  other 
  two 
  tribes. 
  The 
  labial 
  ring 
  

   is 
  narrow 
  but 
  apparently 
  comj)lete, 
  although 
  its 
  lower 
  mari^in 
  peihaps 
  

   outlines 
  the 
  palpal 
  areas 
  rather 
  than 
  the 
  actual 
  basal 
  margin 
  of 
  the 
  

   labium, 
  and 
  there 
  i.s 
  a 
  median 
  e.xten.sion 
  between 
  the 
  palpal 
  areas; 
  

   the 
  brace 
  across 
  the 
  head 
  above 
  the 
  mouth 
  is 
  complete 
  but 
  slender, 
  

   and 
  the 
  part 
  across 
  the 
  clypeus 
  is 
  much 
  more 
  arched 
  than 
  in 
  the 
  therio- 
  

   nine 
  larva; 
  the 
  ma.xillar 
  branch 
  is 
  present 
  but 
  very 
  short; 
  the 
  marginal 
  

   sclerome 
  of 
  the 
  nuixiilary 
  stii)es 
  is 
  long 
  and 
  slender 
  and 
  the 
  cardo 
  is 
  

   not 
  sclerotized, 
  the 
  mandible 
  is 
  stout 
  at 
  the 
  base 
  with 
  a 
  long 
  slender 
  

   point, 
  the 
  two 
  mandibles 
  nearly 
  meeting 
  on 
  the 
  median 
  line. 
  

  

  TERMINOLOGY 
  

  

  For 
  the 
  most 
  part 
  the 
  terminology 
  employed 
  is 
  that 
  characteristic 
  

   of 
  the 
  vast 
  bulk 
  of 
  the 
  literature 
  of 
  the 
  Ichneumonidac, 
  and 
  that 
  of 
  

   the 
  wing 
  veins 
  and 
  cells 
  is 
  in 
  general 
  that 
  of 
  Rohwer 
  and 
  Gahan's 
  

   "Horismology 
  of 
  the 
  Hymen()j)terous 
  Wing." 
  ^ 
  A 
  few 
  new 
  or 
  unusual 
  

   terms, 
  however, 
  need 
  definition: 
  

  

  Abscissula. 
  — 
  The 
  basal 
  abscissa 
  of 
  radiella 
  (pi. 
  53, 
  fig. 
  52). 
  

  

  Basal 
  constrict 
  ion 
  of 
  propodcnm. 
  — 
  The 
  constriction 
  dividing 
  that 
  

   part 
  of 
  propodeum 
  basad 
  of 
  the 
  basal 
  carina 
  or 
  its 
  normal 
  position 
  

   into 
  frenum 
  (anterior 
  portion) 
  and 
  basal 
  area 
  (posterior 
  portion) 
  (pi. 
  

   52, 
  figs. 
  43, 
  44). 
  

  

  Epipleura. 
  — 
  The 
  lateral 
  portions 
  of 
  the 
  tergites 
  extending 
  as 
  free 
  

   flaps 
  beyond 
  the 
  line 
  of 
  attachment 
  of 
  the 
  ventral 
  membrane. 
  On 
  

   tcrgitc 
  2 
  the 
  ej)ipl(!ura 
  are 
  usually 
  set 
  off 
  by 
  carinae 
  and 
  arc 
  infle.xed, 
  

   but 
  are 
  not 
  so 
  defined 
  or 
  inflexed 
  in 
  the 
  Tliyreodon 
  group 
  and 
  in 
  a 
  

   few 
  other 
  genera. 
  

  

  Fenestra. 
  — 
  A 
  hairless 
  area 
  in 
  the 
  ajiical 
  jiortion 
  of 
  the 
  discocubital 
  

   cell 
  usually 
  more 
  or 
  less 
  outlined 
  by 
  sclerotic 
  thickenings 
  (scleromcs) 
  

   and 
  frequently 
  also 
  with 
  one 
  or 
  more 
  scleromes 
  on 
  its 
  surface. 
  This 
  

   and 
  its 
  parts 
  are 
  fully 
  described 
  and 
  discussed 
  in 
  my 
  paper 
  on 
  the 
  

   Ichneumonidac 
  of 
  the 
  Sauter 
  i^'ormo.san 
  collection 
  ^; 
  and 
  the 
  termi- 
  

   nology 
  of 
  the 
  parts 
  is 
  indicated 
  on

  tho 
  present 
  work. 
  

   This 
  structure 
  is 
  characteristic 
  of 
  K/iiros])ilws 
  and 
  absent 
  in

   Ophion 
  and 
  Thyreodon

  (i)l.

  Paramere. 
  — 
  One 
  of 
  tho 
  paired 
  outer 
  valves 
  of 
  the 
  male 
  genitalia 
  

   (pi.

  Postnervulus. 
  -'Yha

  and 
  thiril 
  abscissae 
  of
