  I 
  have 
  described 
  this 
  North 
  American 
  species 
  too 
  recently 
  and 
  too 
  

   fully 
  to 
  make 
  further 
  discussion 
  necessary 
  here. 
  It 
  may 
  well 
  be 
  men- 
  

   tioned, 
  however, 
  that 
  the 
  mesoscutum 
  frequently 
  has, 
  in 
  addition 
  to 
  

   the 
  single 
  median 
  yellow 
  spot, 
  traces 
  of 
  tlie 
  yellow 
  lines 
  along 
  the 
  

   inner 
  margins 
  of 
  the 
  lateral 
  lobes 
  and 
  sometimes 
  those 
  along 
  lateral 
  

   margins 
  next 
  to 
  the 
  tegulae.

  new 
  species 
  

  

  Fennale. 
  — 
  Length 
  14 
  mm., 
  antennae 
  11 
  mm., 
  sheath 
  5 
  mn\. 
  

  

  Except 
  that 
  it 
  has 
  a 
  single 
  median 
  spot 
  on 
  the 
  mesoscutum 
  instead 
  

   of 
  two 
  yellow 
  lines 
  and 
  that 
  the 
  propodeal 
  markings 
  extend 
  narrowly 
  

   forward 
  to 
  the 
  basal 
  carina, 
  this 
  species 
  is 
  very 
  similar 
  in 
  color 
  and 
  in 
  

   large 
  part 
  in 
  structure 
  also 
  to 
  the 
  three 
  species 
  mexicana^ 
  orizabensis, 
  

   and 
  hilineata. 
  The 
  hind 
  legs 
  are 
  colored 
  exactly 
  like 
  those 
  of 
  oriza- 
  

   iensis, 
  as 
  is 
  the 
  mesosternum, 
  while 
  the 
  abdomen 
  is 
  colored 
  like 
  that 
  

   of 
  mexicana. 
  The 
  temples 
  are 
  not 
  at 
  all 
  concave, 
  the 
  cheeks 
  are 
  more 
  

   convex, 
  tlie 
  vertex 
  is 
  flat, 
  the 
  occipital 
  carina 
  is 
  lower, 
  the 
  antennae 
  

   are 
  shorter, 
  the 
  petiole 
  is 
  thicker, 
  with 
  the 
  lateral 
  carinae, 
  both 
  dorsal 
  

   and 
  ventral, 
  more 
  distinct, 
  and 
  the 
  ovipositor 
  longer 
  ; 
  otherwise 
  very 
  

   similar 
  to 
  oiizabensis. 
  

  

  Type 
  locality. 
  — 
  La 
  Caja, 
  near 
  San 
  Jose, 
  Costa 
  E-ica. 
  

  

  Types. 
  — 
  Two 
  females, 
  the 
  holotype 
  and 
  .i 
  paratype, 
  taken 
  at 
  the 
  

   above 
  locality 
  by 
  M. 
  Valeria 
  on 
  July 
  1, 
  1931, 
  at 
  an 
  altitude 
  of 
  900 
  

   meters, 
  and 
  one 
  female 
  paratype 
  captured 
  by 
  Schaus 
  and 
  Barnes 
  at 
  

   Cayuga, 
  Guatemala. 
  All 
  are 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  (No. 
  

   55071). 
  

  

  The 
  Costa 
  Rican 
  paratype 
  is 
  smaller 
  and 
  the 
  Guatemalan 
  paratype 
  

   larger 
  than 
  the 
  type, 
  but 
  otherwise 
  they 
  are 
  similar. 
  

  

  Mesostenus 
  veraepacis 
  Cameron, 
  which 
  seems 
  to 
  be 
  a 
  Ci^ptarmra, 
  

   appears 
  to 
  be 
  very 
  similar 
  to 
  this 
  species 
  but 
  differs 
  in 
  that 
  the 
  hind 
  

   femur 
  is 
  entirely 
  black 
  above 
  without 
  the 
  yellow 
  median 
  line.
