  species 
  

  

  Fcinale. 
  — 
  Length 
  17 
  mm., 
  antennae 
  15 
  mm., 
  ovipositor 
  sheath 
  9 
  mm. 
  

  

  Conspicuous 
  for 
  its 
  large 
  size 
  and 
  long 
  slender 
  ovipositor, 
  this 
  

   species 
  is, 
  nevertheless, 
  very 
  closely 
  allied 
  to 
  pai'anensis 
  and 
  vaHegata^ 
  

   tlilFering 
  from 
  the 
  former 
  principally 
  by 
  the 
  characters 
  employed 
  in 
  

   the 
  key. 
  In 
  structure 
  and 
  sculpture 
  it 
  agrees 
  very 
  well 
  with 
  variegata^ 
  

   while 
  in 
  detail 
  of 
  color, 
  especially 
  of 
  scutellum 
  and 
  propodeum, 
  it 
  is 
  

   more 
  like 
  parancn-sis. 
  The 
  flagellum 
  is 
  somewhat 
  stouter 
  basally 
  than 
  

   in 
  either 
  of 
  the 
  other 
  two 
  species, 
  the 
  first 
  joint 
  of 
  the 
  flagellum 
  being 
  

   distinctly 
  less 
  than 
  six 
  times 
  as 
  long 
  as 
  thick, 
  and 
  the 
  antenna 
  is 
  

   38-jointed, 
  with 
  the 
  annulus 
  embracing 
  flagellar 
  joints 
  (5) 
  6-19 
  (14). 
  

   The 
  ovipositor 
  sheath 
  is 
  nearly 
  as 
  long 
  as 
  the 
  abdomen 
  and 
  the 
  ovi- 
  

   positor 
  very 
  slender, 
  and 
  of 
  uniform 
  depth 
  to 
  the 
  distinctly 
  subsagit- 
  

   tate 
  apex.

  This 
  and 
  the 
  species 
  next 
  following 
  differ 
  from 
  the 
  preceding 
  six 
  

   species 
  in 
  the 
  much 
  shorter 
  and 
  stouter 
  hind 
  femur, 
  which 
  is 
  barely 
  

   two-thirds 
  as 
  long 
  as 
  the 
  tibia. 
  The 
  antenna 
  in 
  this 
  group 
  is 
  some- 
  

   what 
  more 
  slender 
  and 
  less 
  strongly 
  thickened 
  and 
  flattened 
  toward 
  

   the 
  apex. 
  Otherwise 
  these 
  s|X'cies 
  are, 
  in 
  structure 
  and 
  color 
  i)attern, 
  

   very 
  similar 
  to 
  the 
  preceding 
  group.
