  Periiampsis, 
  gen. 
  nov. 
  

  

  This 
  new 
  genus 
  is 
  erected 
  here 
  with 
  Carpophthoromyia 
  pulchella, 
  Austen, 
  as 
  

   type, 
  and 
  includes 
  Carpophthoromyia 
  formosula, 
  Austen, 
  but 
  not 
  Trypeta 
  grata, 
  

   Wied., 
  which 
  probably 
  belongs 
  to 
  Clinotaenia, 
  as 
  stated 
  above. 
  It 
  comprises 
  

   very 
  beautiful 
  (whence 
  the 
  generic 
  name) 
  Ethiopian 
  flies, 
  which 
  agree 
  in 
  coloration 
  

   of 
  the 
  body 
  and 
  in 
  wing 
  pattern, 
  as 
  well 
  in 
  the 
  following 
  characters 
  : 
  —

  in 
  front 
  view 
  broader

  at

  Perilampsis 
  pulchella, 
  Austen, 
  1910. 
  

  

  Of 
  the 
  present 
  species, 
  known 
  from 
  Uganda 
  and 
  Kamerun, 
  there 
  is 
  a 
  specimen 
  

   from 
  S. 
  Abyssinia 
  (R. 
  J. 
  Stordy). 
  The 
  species 
  seems 
  therefore 
  to 
  have 
  a 
  very 
  

   wide 
  distribution 
  over 
  the 
  whole 
  centre 
  of 
  the 
  Ethiopian 
  Region. 
  

  

  Hoplolopha, 
  gen. 
  nov. 
  

   This 
  new 
  genus 
  is 
  a 
  very 
  interesting 
  one, 
  because, 
  although 
  it 
  is 
  without 
  doubt 
  

   closely 
  allied 
  to 
  Ceratitis 
  (s. 
  I.) 
  and 
  has 
  a 
  wing 
  pattern 
  very 
  like 
  that 
  of 
  the 
  preceding 
  

   genus, 
  it 
  shows 
  in 
  the 
  male 
  sex 
  on 
  the 
  frons 
  the 
  cristiform 
  protuberances 
  with
