  vein 
  prolonged 
  to 
  the 
  hind 
  border. 
  The 
  star-shaped 
  apical 
  patch 
  is 
  blackish 
  

   brown 
  ; 
  it 
  encloses 
  a 
  triangular 
  indentation 
  into 
  the 
  marginal 
  cell, 
  two 
  hyaline 
  

   spots 
  near 
  the 
  border 
  at 
  end 
  of 
  the 
  submarginal 
  cell, 
  one 
  just 
  below 
  the 
  end 
  of 
  the 
  

   2nd 
  vein 
  and 
  the 
  other 
  broader 
  and 
  subquadrate 
  before 
  the 
  end 
  of 
  the 
  3rd 
  vein. 
  

   The 
  first 
  posterior 
  cell 
  has 
  two 
  hyaline 
  spots 
  at 
  base, 
  the 
  first 
  as 
  long 
  as 
  the 
  breadth 
  

   of 
  the 
  cell 
  itself 
  and 
  in 
  contact 
  with 
  the 
  small 
  cross- 
  vein, 
  the 
  second 
  rounded, 
  half 
  

   as 
  long, 
  and 
  in 
  contact 
  with 
  the 
  4th 
  longitudinal 
  vein 
  ; 
  the 
  cell 
  has 
  at 
  the 
  end 
  the 
  

   three 
  usual 
  spots, 
  which 
  form 
  the 
  two 
  usual 
  radiating 
  branches 
  ; 
  two 
  other 
  fuscous 
  

   parallel 
  rays 
  are 
  in 
  the 
  second 
  posterior 
  cell, 
  and 
  another 
  less 
  distinct 
  ray 
  on 
  the 
  

   hind 
  cross- 
  vein. 
  The 
  fuscous 
  rays 
  at 
  the 
  apex 
  and 
  hind 
  border 
  are 
  therefore 
  five 
  

   in 
  number. 
  The 
  basal 
  portion 
  of 
  the 
  wing 
  shows 
  a 
  pale 
  but 
  complete 
  reticulation, 
  

   formed 
  by 
  rounded 
  hyaline 
  spots 
  of 
  rather 
  large 
  size 
  ; 
  of 
  these 
  spots 
  there 
  is 
  a 
  row 
  

   only 
  in 
  the 
  base 
  of 
  the 
  submarginal 
  and 
  first 
  basal 
  cells 
  ; 
  the 
  discoidal 
  cell 
  has 
  a 
  

   row 
  in 
  the 
  basal, 
  and 
  two 
  rows 
  in 
  the 
  apical 
  half 
  ; 
  the 
  third 
  posterior 
  cell 
  has 
  ten 
  

   broader 
  spots 
  disposed 
  in 
  two 
  rows, 
  and 
  along 
  the 
  hind 
  border 
  three 
  more 
  spots 
  ; 
  

   axillary 
  cell 
  with 
  six 
  spots 
  in 
  two 
  rows. 
  The 
  base 
  of 
  the 
  second 
  posterior 
  cell 
  has 
  

   three 
  spots, 
  two 
  larger 
  and 
  one 
  small, 
  between 
  the 
  ray 
  of 
  the 
  hind 
  cross-vein 
  and 
  

   the 
  middle 
  ray. 
  The 
  short 
  stigma 
  is 
  quite 
  colourless, 
  with 
  only 
  a 
  black 
  dot 
  near 
  

   the 
  costa 
  at 
  base 
  of 
  the 
  costal 
  bristle 
  ; 
  it 
  is 
  not 
  united 
  with 
  the 
  subapical 
  patch 
  ; 
  

   the 
  oblique 
  ray 
  departing 
  from 
  it 
  and 
  extending 
  to 
  the 
  small 
  cross- 
  vein 
  is 
  very 
  

   faint 
  and 
  belongs 
  to 
  the 
  pale 
  reticulation. 
  

  

  Type 
  §, 
  a 
  single 
  specimen 
  from 
  British 
  East 
  Africa, 
  Nairobi, 
  27.iv.1911 
  (T. 
  J. 
  

   Anderson). 
  

  

  From 
  T. 
  abstersa 
  (which 
  I 
  have 
  in 
  my 
  collection 
  from 
  California, 
  New 
  Mexico 
  

   and 
  Colorado) 
  the 
  present 
  species 
  differs 
  in 
  the 
  closer 
  reticulation 
  of 
  the 
  wings, 
  

   in 
  the 
  wholly 
  colourless 
  stigma, 
  and 
  in 
  the 
  want 
  of 
  the 
  hyaline 
  spot 
  in 
  the 
  marginal 
  

   cell, 
  just 
  above 
  the 
  end 
  of 
  the 
  second 
  longitudinal 
  vein 
  (not 
  to 
  be 
  confounded 
  with 
  

   the 
  hyaline 
  spot 
  in 
  the 
  submarginal 
  cell 
  just 
  below 
  the 
  end 
  of 
  the 
  same 
  vein). 
  

   From 
  T. 
  reticulata 
  it 
  differs 
  in 
  the 
  subapical 
  brown 
  patch 
  being 
  much 
  more 
  extended 
  

   and 
  more 
  typically 
  shaped. 
  

  

  Trypanea 
  peregrina, 
  Adams 
  (1905). 
  

  

  Having 
  had 
  occasion 
  to 
  see 
  the 
  type 
  of 
  this 
  species 
  in 
  the 
  Entomological 
  Museum 
  

   of 
  the 
  University 
  of 
  Kansas, 
  Lawrence, 
  I 
  must 
  recognize 
  that 
  it 
  is 
  the 
  same 
  as 
  my 
  

   T. 
  uropJiora 
  of 
  the 
  preceding 
  paper, 
  as 
  already 
  suspected. 
  The 
  figure 
  11 
  on 
  pi. 
  i, 
  

   is 
  too 
  dark, 
  the 
  ray 
  extending 
  from 
  the 
  stigma 
  to 
  the 
  small 
  cross- 
  vein 
  being 
  really 
  

   much 
  paler 
  and 
  interrupted. 
  The 
  form 
  of 
  the 
  ovipositor 
  is 
  the 
  same, 
  even 
  though 
  

   it 
  is 
  depressed 
  in 
  the 
  type 
  of 
  peregrina.

  A 
  pretty 
  species 
  recalling 
  T. 
  guimari, 
  Becker, 
  from 
  the 
  Canary 
  Islands, 
  and 
  

   likewise 
  with 
  the 
  apical 
  half 
  of 
  the 
  wing 
  only 
  occupied 
  by 
  a 
  not 
  typically 
  star- 
  

   shaped 
  pattern, 
  which 
  shows 
  however 
  more 
  numerous 
  hyaline 
  spots.
