  Tabanus 
  claritibialis, 
  Ric. 
  

  

  This 
  species 
  was 
  found 
  in 
  considerable 
  numbers 
  in 
  January 
  between 
  Mt. 
  Mlanje 
  

   and 
  Lake 
  Chilwa. 
  It 
  had 
  then 
  evidently 
  been 
  on 
  the 
  wing 
  some 
  little 
  time, 
  as 
  the 
  

   females 
  were 
  biting 
  readily 
  and 
  no 
  males 
  were 
  obtainable. 
  

  

  Tabanus 
  thoracinus, 
  P. 
  de 
  B. 
  

  

  Occasional 
  individuals 
  of 
  whet 
  appear 
  to 
  be 
  this 
  species, 
  which 
  is 
  distinguished 
  

   at 
  a 
  glance 
  in 
  life 
  from 
  T. 
  obscuripes 
  in 
  having 
  green 
  eyes 
  instead 
  of 
  brownish-purple 
  

   ones, 
  were 
  captured 
  at 
  Mlanje 
  between 
  October 
  and 
  January. 
  In 
  other 
  respects 
  they 
  

   more 
  resemble 
  T. 
  obscuripes, 
  and 
  further 
  material 
  may 
  prove 
  that 
  though 
  normal 
  

   individuals 
  of 
  that 
  species 
  have 
  brownish-purple 
  eyes, 
  occasional 
  specimens 
  have 
  the 
  

   eyes 
  green 
  like 
  those 
  of 
  T. 
  thoracinus. 
  

  

  Tabanus 
  obscuripes, 
  Ric. 
  

  

  This 
  species 
  occurred 
  in 
  some 
  numbers 
  in 
  October 
  and 
  November, 
  but 
  was 
  less 
  

   common 
  near 
  Mlanje 
  itself 
  than 
  on 
  the 
  plains 
  in 
  Portuguese 
  territory 
  to 
  the 
  east 
  and 
  

   south. 
  In 
  the 
  majority 
  of 
  typical 
  examples 
  the 
  eyes 
  of 
  the 
  female 
  of 
  this 
  species 
  

   are 
  brownish-purple, 
  but 
  in 
  these 
  Mlanje 
  specimens 
  a 
  few 
  individuals 
  had 
  green 
  eyes

  like

  of

  though 
  not 
  differing 
  in 
  other 
  ways. 
  A 
  single 
  male 
  was 
  

   bred 
  from 
  a 
  collected 
  pupa 
  on 
  the 
  1st 
  October. 
  The 
  pupal 
  aster 
  somewhat 
  resembles 
  

   that 
  of 
  T. 
  laverani 
  and 
  has 
  the 
  same 
  very 
  large 
  middle 
  pair 
  of 
  hooks. 
  The 
  dorso- 
  

   lateral 
  comb 
  is 
  reduced 
  to 
  a 
  single 
  knob-like 
  process.

  Though 
  never 
  a 
  common 
  insect 
  in 
  the 
  Mlanje 
  district, 
  occasional 
  specimens 
  of 
  this 
  

   species 
  were 
  taken 
  over 
  a 
  wide 
  area 
  from 
  October 
  to 
  January. 
  

  

  Tabanus 
  medionotatus, 
  Aust. 
  

  

  A 
  series 
  was 
  obtained 
  comprising 
  a 
  single 
  male 
  and 
  a 
  large 
  number 
  of 
  females 
  which 
  

   are 
  attributable 
  with 
  some 
  doubt 
  to 
  this 
  species. 
  They 
  are 
  readily 
  distinguishable
