  1918. 
  

   Leucotaeniella 
  guttipennis, 
  sp. 
  nov. 
  (PL 
  xvii, 
  fig. 
  3). 
  

  

  Very 
  like 
  trispila 
  in 
  the 
  scutellar 
  pattern, 
  but 
  distinct 
  from 
  it 
  and 
  from 
  the 
  other 
  species 
  

   on 
  account 
  of 
  its 
  peculiar 
  wing 
  pattern, 
  which 
  approaches 
  that 
  of 
  the 
  reticulate 
  type. 
  

  

  ?. 
  Length 
  of 
  body 
  6-6 
  '5 
  mm. 
  ; 
  of 
  ovipositor 
  1 
  mm. 
  ; 
  of 
  wing 
  5-6*5 
  mm. 
  

  

  Head 
  exactly 
  as 
  in 
  trispila, 
  but 
  without 
  the 
  black 
  ocellar 
  dot, 
  and 
  the 
  semi- 
  

   circular 
  spot 
  in 
  the 
  middle 
  of 
  the 
  frontal 
  stripe 
  is 
  paler 
  and 
  less 
  distinct. 
  Thorax, 
  

   scutellum 
  and 
  halteres 
  as 
  in 
  trispila 
  ; 
  the 
  black 
  apical 
  scutellar 
  spot 
  is 
  less 
  developed, 
  

   being 
  much 
  smaller 
  than 
  the 
  space 
  between 
  the 
  apical 
  pair 
  of 
  bristles, 
  and 
  not 
  

   at 
  all 
  visible 
  from 
  above. 
  Abdomen 
  similar, 
  but 
  the 
  ovipositor 
  not 
  darkened 
  at 
  

   end 
  ; 
  legs 
  entirely 
  similar. 
  The 
  wings 
  in 
  shape, 
  coloration 
  and 
  venational 
  

   characters 
  are 
  exactly 
  as 
  in 
  trispila, 
  but 
  they 
  show 
  conspicuous 
  differences 
  in 
  the 
  

   pattern. 
  This 
  last 
  in 
  its 
  general 
  features 
  is 
  of 
  the 
  same 
  type, 
  but 
  the 
  middle 
  and 
  

   cubital 
  bands 
  are 
  broadly 
  fused 
  together 
  and 
  even 
  with 
  the 
  marginal 
  and 
  anal 
  

   bands, 
  forming 
  thus 
  a 
  single 
  broad 
  patch 
  filling 
  up 
  the 
  apical 
  two-thirds 
  of 
  the 
  

   wing, 
  interrupted 
  by 
  some 
  rounded 
  hyaline 
  spots, 
  which 
  form 
  a 
  kind 
  of 
  broad 
  reticu- 
  

   lation. 
  The 
  basal 
  band 
  is 
  broadly 
  united 
  with 
  the 
  anal 
  one 
  in 
  the 
  submarginal 
  

   and 
  first 
  basal 
  cells, 
  thus 
  forming 
  a 
  rounded 
  hyaline 
  spot 
  in 
  the 
  marginal 
  cell 
  just 
  

   below 
  the 
  stigma, 
  and 
  a 
  hyaline 
  indentation 
  which 
  ends 
  above 
  in 
  the 
  middle 
  of 
  

   the 
  first 
  basal 
  cell. 
  The 
  stigma 
  is 
  blackish 
  on 
  the 
  basal 
  half, 
  and 
  almost 
  hyaline 
  

   in 
  the 
  apical 
  one 
  ; 
  the 
  second 
  costal 
  cell 
  is 
  hyaline, 
  with 
  the 
  two 
  ends 
  narrowly 
  

   infuscated. 
  The 
  anal 
  band 
  is 
  broader, 
  and 
  infuscated 
  on 
  its 
  lower 
  part; 
  the 
  

   marginal 
  band 
  has 
  a 
  broad 
  hyaline 
  spot 
  before 
  the 
  end 
  of 
  the 
  marginal 
  cell 
  (which 
  

   shows 
  therefore 
  two 
  broad 
  hyaline 
  spots), 
  and 
  another 
  at 
  wing 
  border 
  before 
  the 
  

   end 
  of 
  the 
  submarginal 
  cell, 
  which 
  has 
  another 
  hyaline 
  spot 
  in 
  the 
  middle 
  just 
  below 
  

   but 
  much 
  smaller 
  than 
  the 
  apical 
  one 
  of 
  the 
  marginal 
  cell 
  ; 
  the 
  first 
  posterior 
  cell 
  

   is 
  entirely 
  infuscated, 
  yellowish 
  on 
  the 
  basal 
  part 
  and 
  fuscous 
  on 
  the 
  apical, 
  with 
  

   three 
  rounded 
  hyaline 
  spots, 
  two 
  of 
  which 
  are 
  in 
  the 
  middle 
  (one 
  behind 
  the 
  other), 
  

   and 
  one 
  at 
  the 
  end 
  in 
  the 
  lower 
  apical 
  corner 
  just 
  above 
  the 
  end 
  of 
  the 
  fourth 
  

   longitudinal 
  vein 
  and 
  passing 
  a 
  little 
  below 
  it. 
  The 
  second 
  posterior 
  cell 
  has 
  two 
  

   hyaline 
  spots 
  at 
  the 
  border 
  with 
  a 
  less 
  defined 
  light 
  (but 
  not 
  hyaline) 
  space 
  above 
  

   them 
  ; 
  the 
  discoidal 
  cell 
  has 
  a 
  rounded 
  hyaline 
  spot 
  before 
  its 
  apex, 
  united 
  with 
  

   the 
  indentation 
  of 
  the 
  third 
  posterior 
  cell. 
  All 
  these 
  hyaline 
  spots 
  and 
  indentations 
  

   are 
  broadly 
  margined 
  with 
  fuscous 
  ; 
  but 
  the 
  hind 
  cross- 
  vein 
  is 
  entirely 
  on 
  the 
  

   yellowish 
  part, 
  being 
  nearer 
  to 
  the 
  fuscous 
  border 
  of 
  the 
  spots 
  of 
  the 
  second 
  posterior 
  

   cell 
  than 
  to 
  that 
  of 
  the 
  indentation 
  of 
  the 
  discoidal 
  cell. 
  

  

  Type 
  $, 
  a 
  single 
  specimen 
  from 
  N. 
  Nigeria, 
  Zungeru,18.xi.l910 
  (Dr. 
  J. 
  W. 
  Scott 
  

   Macfie). 
  An 
  additional 
  female 
  specimen 
  from 
  the 
  same 
  locality 
  and 
  collector 
  differs 
  

   only 
  in 
  having 
  three 
  (instead 
  of 
  two) 
  hyaline 
  spots 
  in 
  the 
  submarginal 
  cell 
  along 
  

   the 
  costa, 
  a 
  third 
  (half 
  as 
  small) 
  hyaline 
  spot 
  being 
  present 
  between 
  the 
  two 
  spots 
  

   of 
  the 
  type. 
  

  

  Bisirispinaria, 
  Speiser, 
  1913. 
  

  

  Owing 
  to 
  the 
  fact 
  that 
  the 
  present 
  very 
  distinct 
  genus 
  was 
  shortly 
  characterised 
  

   by 
  Dr. 
  Speiser 
  as 
  a 
  section 
  of 
  Ceratitis, 
  I 
  will 
  give 
  here 
  a 
  more 
  complete 
  description 
  

   of 
  it. 
  It 
  is 
  more 
  closely 
  allied 
  to 
  the 
  genera 
  Chelyophora 
  and 
  Acroceratitis, 
  than 
  

   to 
  those 
  that 
  have 
  been 
  separated 
  by 
  me 
  from 
  Ceratitis, 
  s.l.
