  A. 
  NEAVE. 
  

  

  at 
  the 
  end 
  of 
  October 
  and 
  beginning 
  of 
  November. 
  The 
  larva 
  (Plate 
  xxviii, 
  fig. 
  14) 
  

   resembles 
  that 
  of 
  T. 
  biguttatus, 
  but 
  is 
  less 
  pigmented. 
  

  

  The 
  upper 
  hooks 
  of 
  the 
  pupal 
  aster 
  are 
  considerably 
  larger 
  than 
  the 
  remainder. 
  

   The 
  spines 
  of 
  the 
  dorso-lateral 
  comb 
  are 
  much 
  reduced, 
  especially 
  in 
  the 
  male. 
  

  

  Tabanus 
  denshami, 
  Aust. 
  

  

  This 
  species 
  occurs 
  sparingly 
  in 
  the 
  neighbourhood 
  of 
  Mt. 
  Mlanje 
  in 
  October 
  and 
  

   November. 
  It 
  is 
  commoner 
  in 
  the 
  lower 
  and 
  drier 
  ground 
  lying 
  out 
  from 
  the 
  moun- 
  

   tain. 
  Like 
  most 
  Nyasaland 
  and 
  Rhodesian 
  specimens, 
  the 
  abdominal 
  markings 
  

   are 
  much 
  less 
  strongly 
  developed 
  than 
  in 
  examples 
  from 
  British 
  East 
  Africa 
  and 
  

   Uganda. 
  

  

  Tabanus 
  fraternus, 
  Macq. 
  

  

  This 
  Tabanus 
  is 
  uncommon 
  in 
  so 
  damp 
  and 
  well 
  wooded 
  a 
  locality 
  as 
  Mt. 
  Mlanje, 
  

   though 
  a 
  single 
  female 
  was 
  bred 
  on 
  16th 
  December 
  1914, 
  from 
  a 
  locally 
  collected 
  

   larva, 
  which 
  was 
  not 
  recognised 
  as 
  distinct 
  from 
  that 
  of 
  T. 
  taeniola.

  (6) 
  the 
  dorso- 
  

  

  The 
  pupal 
  aster 
  resembles 
  that 
  of 
  T. 
  maculatissimus 
  in 
  having 
  a 
  small 
  papilla 
  

   on 
  each 
  side 
  of 
  the 
  middle 
  line. 
  The 
  dorso-lateral 
  comb 
  consists 
  of 
  only 
  a 
  small 
  

   number 
  of 
  spines, 
  which, 
  though 
  rather 
  long, 
  are 
  fairly 
  stout. 
  

  

  Tabanus 
  distinctus, 
  Eic. 
  

  

  An 
  uncommon 
  species 
  near 
  Mt. 
  Mlanje 
  itself, 
  as 
  it 
  prefers 
  drier 
  country. 
  It 
  was 
  

   fairly 
  numerous 
  in 
  Portuguese 
  territory 
  to 
  the 
  south 
  and 
  east 
  of 
  the 
  mountain. 
  

  

  Tabanus 
  coniformis, 
  Ric. 
  

  

  This 
  species 
  is 
  usually 
  commonest 
  in 
  moderately 
  open 
  country 
  and 
  is 
  therefore 
  not 
  

   abundant 
  at 
  Mt. 
  Mlanje, 
  though 
  a 
  large 
  series 
  was 
  taken 
  in 
  the 
  district, 
  especially 
  

   in 
  Portuguese 
  territory, 
  in 
  October. 
  

  

  Tabanus 
  sandersoni, 
  Aust. 
  

  

  This 
  is 
  a 
  widely 
  distributed 
  but 
  not 
  very 
  abundant 
  species 
  near 
  Mt. 
  Mlanje, 
  and 
  

   is 
  one 
  of 
  the 
  latest 
  species 
  of 
  the 
  genus, 
  occurring 
  from 
  January 
  to 
  April. 
  It 
  is 
  not 
  

   uncommonly 
  taken 
  towards 
  dusk, 
  which 
  is 
  not 
  usual 
  among 
  flies 
  of 
  this 
  genus.
