  Thorax 
  golden

  a

  Abdomen 
  orange-fulvous, 
  

   somewhat 
  darker 
  at 
  extremity, 
  with 
  a 
  black 
  median 
  stripe, 
  much 
  better 
  marked 
  

   than 
  in

   The

  that 
  of

  a

  Genus 
  Haematopota. 
  

  

  This 
  genus 
  was 
  well 
  represented 
  in 
  the 
  neighbourhood 
  of 
  Mt. 
  Mlanje, 
  and 
  several 
  

   species 
  were 
  collected 
  which 
  are 
  probably 
  new 
  to 
  science, 
  but 
  are 
  not 
  included 
  in 
  

   this 
  paper. 
  The 
  larvae 
  were 
  by 
  no 
  means 
  easy 
  to 
  obtain 
  as 
  compared 
  with 
  those 
  of 
  

   Chrysops, 
  a 
  few 
  individuals 
  of 
  three 
  species 
  only 
  being 
  found 
  in 
  September 
  and 
  

   October. 
  Later 
  in 
  the 
  season, 
  in 
  January, 
  considerable 
  numbers 
  of 
  the 
  larvae 
  of 
  

   an 
  unidentified 
  species 
  were 
  obtained, 
  perhaps 
  those 
  of 
  H. 
  insatiabilis 
  or 
  an 
  allied 
  

   species. 
  The 
  larvae 
  all 
  seem 
  to 
  resemble 
  each 
  other 
  closely 
  and 
  it 
  is 
  very 
  difficult 
  

   to 
  distinguish 
  specific 
  differences 
  in 
  them, 
  though 
  they 
  differ 
  in 
  a 
  marked 
  manner 
  from 
  

   those 
  of 
  any 
  other 
  genus 
  of 
  Tabanidae 
  which 
  I 
  have 
  seen. 
  The 
  differences 
  between 
  

   these 
  larvae 
  and 
  those 
  of 
  Chrysops 
  have 
  already 
  been 
  discussed 
  under 
  that 
  genus. 
  

   The 
  limitation 
  of 
  the 
  pigmented 
  areas 
  to 
  the 
  anal 
  segment 
  and 
  the 
  abruptly 
  truncated 
  

   syphon 
  seem 
  to 
  be 
  characteristic 
  of 
  and 
  peculiar 
  to 
  this 
  genus, 
  as 
  also 
  are 
  the 
  very 
  

   short, 
  sometimes 
  almost 
  invisible, 
  pseudopodia.
