  PLOIARIA 
  BRUNNEA, 
  new 
  species. 
  

  

  A 
  much 
  darker 
  species 
  than 
  macrophthalma, 
  differing 
  as 
  stated 
  

   in 
  key 
  and 
  in 
  having 
  a 
  much 
  more 
  noticeable 
  white 
  annulus 
  at 
  apex 
  

   of 
  each 
  of 
  the 
  first 
  two 
  segments 
  of 
  antenna, 
  that 
  on 
  basal 
  one- 
  

   being 
  much 
  narrower. 
  

  

  Head 
  as 
  in 
  figure 
  69, 
  not 
  so 
  much 
  narrowed 
  posteriorly 
  as 
  in 
  

   macro 
  phthafona. 
  Antennae 
  and 
  fore 
  legs 
  similar 
  to 
  those 
  of 
  pre- 
  

   ceding 
  species 
  in 
  proportions. 
  Pronotum 
  and 
  mesonotum 
  slightly 
  

   granulose 
  and 
  subopaque, 
  not 
  conspicuously 
  shining 
  as 
  in 
  macro- 
  

   phthalma, 
  nor 
  so 
  gradually 
  tapered. 
  

  

  Fore 
  wing 
  more 
  conspicuously 
  marked 
  than 
  in 
  preceding 
  species, 
  

   the 
  dark 
  marks 
  in 
  cells 
  more 
  or 
  less 
  distinctly 
  radiating 
  from 
  a 
  cen- 
  

   tral 
  spot 
  or 
  streak. 
  Apical 
  tergite 
  of 
  male 
  less 
  concave 
  than 
  in 
  

   preceding 
  species, 
  the 
  hypopygium 
  with 
  a 
  strong 
  blunt 
  upwardly 
  

   directed 
  protuberance 
  in 
  center, 
  not 
  conspicuously 
  haired, 
  the 
  claspers 
  

   stouter 
  and 
  more 
  circularly 
  curved, 
  gradually 
  tapered 
  from 
  base.
