  Transvaal 
  : 
  Amersfoort 
  (Claude 
  Fuller). 
  

  

  This 
  species 
  is 
  reported 
  as 
  infesting 
  the 
  leaves 
  of 
  the 
  peach. 
  I 
  have 
  previously 
  

   described 
  another 
  and 
  somewhat 
  allied 
  species 
  (0. 
  exitiosus, 
  Dist., 
  " 
  Entomologist," 
  

   1905, 
  p. 
  169) 
  from 
  near 
  Cape 
  Town, 
  which 
  was 
  also 
  recorded 
  as 
  " 
  injurious 
  to 
  peach." 
  

   As 
  there 
  are 
  now 
  three 
  allied 
  species, 
  the 
  following 
  synopsis 
  may 
  be 
  useful 
  : 
  — 
  

  

  Pronotum 
  with 
  the 
  anterior 
  lobe 
  black, 
  the 
  posterior 
  lobe 
  sanguineous 
  : 
  

  

  Corium 
  red 
  ; 
  abdomen 
  beneath 
  sanguineous, 
  the 
  apex 
  black. 
  0. 
  annulipes, 
  

  

  Germ.* 
  

   Corium 
  red, 
  the 
  lateral 
  margins 
  lutescent 
  ; 
  abdomen 
  beneath 
  sanguineous, 
  the 
  

  

  apex 
  and 
  lateral 
  margins 
  black. 
  0. 
  exitiosus, 
  Dist. 
  

   Corium 
  pale 
  grey 
  hyaline.

  These 
  characters 
  are 
  taken 
  from 
  Germar's 
  description. 
  I 
  have 
  not 
  seen 
  the 
  species.
