  toward 
  apex; 
  coxae 
  and 
  trochanters 
  black 
  or 
  

   blackish; 
  the 
  femora 
  varying 
  from 
  entirely 
  ferrugino-testaceous 
  

   to 
  almost 
  entirely 
  black; 
  even 
  in 
  specimens 
  having 
  the

   femora 
  wholly 
  ferruginous 
  the

  tibiae 
  are 
  entirely 
  black

   at

  their

  In 
  this 
  series 
  the 
  number 
  of 
  

   segments 
  in 
  the 
  antennae 
  varies 
  from 
  32

  Exceedingly 
  similar 
  to 
  sesiae; 
  but 
  the 
  antennal 
  segments 
  are 
  even 
  

   stouter 
  than 
  in 
  that 
  species; 
  the 
  radial 
  cell 
  is 
  shorter; 
  the 
  last 
  ab- 
  

   scissa 
  of 
  radius 
  is 
  distinctly 
  shorter 
  than 
  the 
  last 
  abscissa 
  of 
  cubitus 
  ; 
  

   and 
  the 
  duskiness 
  of 
  the 
  posterior 
  tibiae 
  is 
  confined 
  to 
  the 
  apical 
  

   third. 
  The 
  antennae 
  are 
  very 
  stout, 
  most 
  of 
  the 
  flagellar 
  segments 
  

   being 
  not 
  longer 
  than 
  broad 
  and 
  some 
  of 
  them 
  being 
  broader 
  tha-i 
  

   long; 
  opening 
  between 
  clypeus 
  and 
  mandibles 
  large; 
  the 
  thorax 
  is 
  

   not 
  quite 
  so 
  deep 
  as 
  in 
  sesiae, 
  being 
  twice 
  as 
  long 
  as 
  its 
  greatest 
  

   height; 
  in 
  the 
  sculpture 
  of 
  the 
  abdomen 
  and 
  the 
  color 
  of 
  the 
  body 
  

   the 
  two 
  species 
  agree 
  almost 
  exactly; 
  the 
  difference 
  in 
  the 
  color 
  of 
  

   the 
  tibiae 
  noted 
  above 
  appears 
  to 
  be 
  constant 
  ; 
  the 
  ovipositor 
  sheaths 
  

   are 
  about 
  as 
  long 
  as 
  the 
  abdomen.
