  The 
  more 
  important 
  characters 
  of 
  the 
  genus 
  are 
  as 
  follows: 
  Head 
  

   transverse; 
  ocelli 
  close 
  together, 
  the 
  lateral 
  ones 
  remote 
  from 
  the 
  eye 
  

   margin; 
  antennae 
  12-jointed 
  in 
  both 
  sexes, 
  in 
  the 
  female 
  with 
  a 
  com- 
  

   pact 
  6-jointed 
  club, 
  in 
  the 
  male 
  filiform, 
  the 
  flagellar 
  joints 
  usually 
  

   long; 
  thorax 
  stout; 
  pronotum 
  not 
  or 
  scarcely 
  visible 
  from 
  above; 
  

   parapsidal 
  grooves 
  absent, 
  complete, 
  or 
  partly 
  complete; 
  scutellum 
  

   semicircular, 
  unarmed; 
  metanotum 
  with 
  one 
  tooth 
  or 
  spine 
  wliich 
  

   may 
  be 
  very 
  short, 
  hardly 
  distinguishable, 
  or 
  long, 
  extending 
  well 
  

   over 
  the 
  petiole; 
  propodeum 
  short, 
  frequently 
  armed 
  with 
  a 
  tooth 
  at 
  

   the 
  posterior 
  angles; 
  front 
  wings 
  often 
  abbreviated, 
  in 
  one 
  Nearctic 
  

   species 
  absent; 
  marginal 
  vein 
  very 
  long, 
  much 
  longer 
  than 
  the 
  stigmal 
  

   vein; 
  radius 
  short; 
  postmarginal 
  vein 
  absent; 
  abdomen 
  rather 
  short, 
  

   broadly 
  oval, 
  narrowed 
  at 
  base; 
  first 
  segment 
  subpetiolate, 
  sometimes 
  

   with 
  a 
  slight 
  basal 
  prominence 
  in 
  the 
  female; 
  tliird 
  segment 
  the 
  

   longest; 
  segments 
  4-6 
  short. 
  

  

  CHARACTERS 
  USED 
  IN 
  CLASSIFICATION 
  

  

  Characters 
  found 
  in 
  the 
  surface 
  sculpture 
  of 
  the 
  frons, 
  mesonotum, 
  

   and 
  the 
  first 
  three 
  tergites 
  of 
  the 
  abdomen 
  have 
  proved 
  to 
  be 
  the 
  most 
  

   useful 
  and 
  reliable. 
  A 
  median 
  carina 
  usually 
  extends 
  from 
  the 
  bases 
  

   of 
  the 
  antennae 
  all 
  the 
  way 
  to 
  the 
  anterior 
  ocellus. 
  In 
  one 
  species 
  

   this 
  carina 
  is 
  entirely 
  absent 
  and 
  in 
  several 
  others 
  it 
  is 
  shortened 
  above, 
  

   not 
  present 
  below 
  the 
  ocellus. 
  All 
  the 
  species 
  known 
  to 
  the 
  author 
  

   have 
  striations 
  on 
  the 
  frons. 
  These 
  striae 
  are 
  usually 
  short, 
  but 
  in 
  

   some 
  species 
  they 
  tend 
  to 
  become 
  longer 
  and 
  sometimes 
  extend 
  the 
  

  

  6 
  Order 
  Ilymenoptera: 
  family 
  Scelionidae: 
  subfamily 
  Teleasinae.
