  Northern

  : 
  type 
  from 
  Ngoa, 
  Mpika 
  Division, 
  between 
  Sept. 
  15th 
  and 
  

   Oct. 
  18th, 
  1913, 
  bred 
  from 
  puparium 
  of 
  Glossina 
  morsitans, 
  Westw. 
  (LI. 
  Lloyd 
  : 
  

   presented 
  to 
  the 
  British 
  Museum 
  by 
  the 
  Imperial 
  Bureau 
  of 
  Entomology). 
  

  

  So 
  far 
  as 
  the 
  author 
  is 
  aware, 
  Villa 
  lloydi 
  is 
  the 
  first 
  Dipteron 
  to 
  be 
  recorded 
  as 
  

   parasitic 
  on 
  any 
  tsetse-fly, 
  and 
  Mr. 
  Lloyd, 
  in 
  whose 
  honour 
  the 
  new 
  species 
  is 
  named, 
  

   is 
  heartily 
  to 
  be 
  congratulated 
  on 
  a 
  most 
  interesting 
  discovery. 
  

  

  In 
  conclusion, 
  it 
  is 
  perhaps 
  advisable 
  to 
  add 
  a 
  few 
  words 
  as 
  to 
  the 
  

   systematic 
  position 
  of 
  the 
  species 
  described 
  above. 
  Owing 
  to 
  the 
  shape 
  of 
  the 
  

   discal 
  and 
  third 
  posterior 
  cells 
  in 
  the 
  wing 
  (see 
  fig. 
  1), 
  the 
  venation 
  in 
  this 
  species 
  is 
  

   not 
  that 
  of 
  a 
  typical 
  member 
  of 
  the 
  genus 
  Villa, 
  Lioy. 
  As 
  regards 
  the 
  details 
  

   mentioned, 
  V. 
  lloydi 
  resembles 
  certain 
  Ethiopian 
  species 
  assigned 
  by 
  Bezzi 
  to 
  the 
  

   subgenus 
  Thyridanthrax, 
  0. 
  Sack., 
  though 
  the 
  species 
  referred 
  to 
  are 
  themselves 
  

   aberrant 
  in 
  these 
  respects, 
  as 
  also 
  in 
  their 
  wings 
  being 
  entirely 
  or 
  almost 
  entirely 
  

   hyaline. 
  Villa 
  lloydi, 
  however, 
  cannot 
  be 
  included 
  in 
  Thyridanthrax, 
  since 
  the 
  face 
  

   instead 
  of 
  being 
  conical 
  is 
  merely 
  bluntly 
  convex. 
  Although 
  it 
  may 
  ultimately 
  prove 
  

   necessary 
  to 
  institute 
  a 
  new 
  subgenus 
  for 
  the 
  reception 
  of 
  this 
  species, 
  such 
  a 
  step 
  

   must 
  in 
  any 
  case 
  be 
  postponed 
  until 
  further 
  material 
  is 
  received.
