  Female. 
  — 
  Length 
  13-16 
  mm. 
  

  

  Structurally 
  very 
  similar 
  to 
  aclnaces 
  but 
  with 
  temples 
  weakly 
  con- 
  

   vex; 
  apophyses 
  rather 
  slender. 
  

  

  Body 
  color 
  almost 
  exactly 
  as 
  in 
  aclnaces 
  except 
  that 
  the 
  mandibles 
  

   apparently 
  are 
  always 
  yellow 
  at 
  the 
  base 
  and 
  the 
  orbital 
  rings 
  are 
  

   very 
  narrow 
  or 
  even 
  interrupted 
  in 
  the 
  temples, 
  and 
  the 
  scutellum 
  

   is 
  more 
  or 
  less 
  black 
  at 
  the 
  base 
  ; 
  but 
  the 
  legs 
  are 
  yellow, 
  with 
  the 
  front 
  

   and 
  middle 
  coxae, 
  trochanters, 
  and 
  femora 
  piceous 
  behind, 
  the 
  hind 
  

   coxa 
  with 
  a 
  broad 
  piceous 
  stripe 
  on 
  the 
  outer 
  side 
  of 
  the 
  upper 
  sur- 
  

   face 
  and 
  a 
  shorter 
  one 
  on 
  the 
  inner 
  side, 
  the 
  hind 
  trochanter 
  piceous 
  

   with 
  a 
  trace 
  of 
  yellow 
  on 
  the 
  upper 
  and 
  lower 
  surfaces 
  of 
  the 
  basal 
  

   joint, 
  and 
  the 
  hind 
  femur 
  piceous 
  above 
  and 
  on 
  the 
  inner 
  surface. 
  

  

  Before 
  me 
  are 
  a 
  paratype 
  and 
  another 
  female 
  from 
  Mexico 
  (Fron- 
  

   tera, 
  Tabasco) 
  ; 
  a 
  pair 
  from 
  San 
  Jose, 
  Costa 
  Rica 
  (M. 
  Valerio,

   101) 
  ; 
  two 
  females 
  from 
  Costa 
  Rica 
  (Paul 
  Serre, 
  1920) 
  ; 
  and 
  one 
  female 
  

   from 
  Nicaragua 
  (Mniszech, 
  1871), 
  the 
  last 
  three 
  received 
  from 
  the 
  

   Paris 
  Museum. 
  

  

  The 
  male 
  has 
  the 
  malar 
  sj^ace 
  shorter, 
  the 
  frontal 
  horns 
  more 
  slen- 
  

   der 
  and 
  separated, 
  the 
  apophyses 
  reduced 
  to 
  high 
  elevations 
  in 
  the 
  

   apical 
  carina, 
  which 
  is 
  distinct 
  and 
  sharply 
  angulated 
  medially, 
  the 
  

   petiolar 
  area 
  defined 
  laterally 
  by 
  curved 
  carinae, 
  the 
  apical 
  slope 
  of 
  

   propodeum 
  not 
  distinctly 
  transversely 
  striate 
  and 
  the 
  space 
  between 
  

   the 
  carinae 
  longitudinally 
  striate, 
  and 
  the 
  abdomen 
  small 
  and 
  slender

  PRETIOSA 
  (Viereck),

  Polyacnidia 
  pretiosa 
  Viereck, 
  Proc. 
  U. 
  S. 
  Nat. 
  Mus., 
  vol. 
  46, 
  p. 
  382, 
  1913. 
  

  

  This 
  species 
  differs 
  from 
  all 
  the 
  other 
  species 
  with 
  red 
  abdomen 
  

   which 
  follow 
  it 
  in 
  the 
  present 
  arrangement 
  in 
  its 
  entirely 
  red 
  front 
  

   and 
  middle 
  femora 
  and 
  in 
  the 
  form 
  of 
  the 
  yellow 
  marking 
  of 
  the 
  

   lower 
  division 
  of 
  the 
  metapleuron. 
  The 
  latter 
  is 
  in 
  the 
  form 
  of 
  an 
  oval 
  

   spot 
  extending 
  forward 
  from 
  the 
  hind 
  coxa, 
  whereas 
  in 
  the 
  other 
  

   species 
  it 
  either 
  extends 
  the 
  entire 
  length 
  of 
  the 
  sclerite 
  or 
  has 
  an 
  

   angular 
  forward 
  extension 
  above.
