  pp. 
  44-45 
  [Southern

  The 
  female 
  of 
  P. 
  hirticornis. 
  

  

  This 
  species 
  closely 
  resembles 
  the 
  last 
  in 
  structure 
  of 
  the 
  fore 
  

   legs, 
  but 
  the 
  coxae 
  are 
  more 
  slender 
  and 
  nearly 
  twice 
  as 
  long 
  as 
  the 
  

   tibiae, 
  the 
  fore 
  tarsi 
  are 
  as 
  long 
  as 
  the 
  tibiae, 
  the 
  elevated 
  bases 
  of 
  

   the 
  long 
  spines 
  of 
  postero-ventral 
  series 
  are 
  about 
  as 
  in 
  the 
  last 
  

   species, 
  white, 
  and 
  the 
  spines 
  are 
  blackish; 
  the 
  pronotum 
  is 
  longer 
  

   and 
  narrower 
  than 
  in 
  granulosa, 
  the 
  abdomen 
  has 
  no 
  lateral 
  projec- 
  

   tions 
  on 
  tergites 
  and 
  the 
  dorsal 
  tubercles 
  are 
  small 
  anteriorly, 
  in- 
  

   creasing 
  in 
  size 
  posteriorly 
  ; 
  the 
  seventh 
  tergite 
  of 
  the 
  female 
  has 
  the 
  

   lateral 
  angles 
  slightly 
  produced 
  and 
  a 
  longer 
  central 
  process 
  (fig. 
  

   90) 
  ; 
  the 
  apical 
  border 
  of 
  the 
  male 
  hypopygium 
  is 
  as 
  in 
  figure 
  91; 
  

   apical 
  tergite 
  as 
  in 
  figure 
  92. 
  All 
  our 
  specimens 
  have 
  minute 
  wing 
  

   pads 
  except 
  one 
  male 
  paratype 
  which 
  is 
  fully 
  winged 
  ; 
  the 
  wings 
  are 
  

   rather 
  closely 
  reticulated 
  with 
  fuscous, 
  the 
  heaviest 
  markings 
  being 
  

   in 
  discal 
  cell 
  and 
  along 
  hind 
  side 
  of 
  vein 
  emanating 
  from 
  it.
