  U.S.N.M. 
  

  

  Separated 
  from 
  xanthonotus 
  and 
  platynotae 
  by 
  the 
  antennae, 
  

   which, 
  especially 
  in 
  the 
  female, 
  are 
  stout 
  and 
  taper 
  toward 
  the 
  tip 
  ; 
  

   and 
  by 
  the 
  paler 
  head 
  and 
  thorax. 
  It 
  is 
  further 
  distinguished 
  from 
  

   platynotae 
  by 
  the 
  usually 
  coarser 
  longitudinal 
  sculpture 
  of 
  the 
  second 
  

   tergite, 
  and 
  from 
  xanthonotus 
  by 
  the 
  longer 
  ovipositor 
  sheaths, 
  which 
  

   are 
  a 
  little 
  more 
  than 
  half 
  as 
  long 
  as 
  the 
  abdomen. 
  Head 
  and 
  thorax 
  

   entirely 
  finely 
  granularly 
  sculptured; 
  antennae 
  of 
  female

  19 
  

   to 
  22-segmented 
  ;

  21 
  to 
  25 
  segmented; 
  malar 
  space 
  

   of 
  female 
  at 
  least 
  as 
  long 
  as 
  the 
  first 
  flagellar 
  segment; 
  of 
  male, 
  

   nearly 
  as 
  long; 
  wings 
  a 
  little 
  dusky 
  on 
  basal 
  half 
  or 
  more; 
  second 
  

   abscissa 
  of 
  radius 
  only 
  a 
  little 
  or 
  no 
  longer 
  than 
  the 
  first; 
  last 
  ab- 
  

   scissa 
  of 
  radius 
  as 
  long 
  as 
  the 
  last 
  abscissa 
  of 
  cubitus, 
  the 
  latter 
  not 
  

   distinctly 
  twice 
  the 
  preceding 
  abscissa 
  of 
  cubitus; 
  the 
  portion 
  of 
  

   cubitus 
  between 
  recurrent 
  and 
  first 
  intercubitus 
  fully 
  as 
  long 
  as 
  

   recurrent 
  ; 
  abdomen 
  entirely 
  or 
  nearly 
  entirely 
  sculptured, 
  the 
  second 
  

   tergite 
  coarsely 
  so 
  ; 
  the 
  oblique 
  grooves 
  on 
  first 
  tergite 
  usually 
  f 
  oveo- 
  

   late; 
  head, 
  thorax, 
  and 
  abdomen 
  usually 
  mostly 
  testaceous, 
  the 
  

   thorax 
  often 
  more 
  or 
  less 
  fuscous 
  ; 
  legs 
  mostly 
  yellowish-brown.

  Type.— 
  Cat. 
  No.

  U.S.N.M. 
  

  

  Distinguished 
  from 
  cushm,ani 
  as 
  noted 
  under 
  that 
  species; 
  from 
  

   xanthonotus 
  it 
  differs 
  especially 
  by 
  the 
  characters 
  given 
  in 
  the 
  key; 
  

   from 
  gelechiae, 
  which 
  it 
  very 
  closely 
  resembles 
  in 
  general 
  appearance
