  Thorax.

  20-22 
  bristles 
  in 
  the 
  posterior 
  row. 
  Mesonotum 
  with 
  

   the 
  scutum 
  pattern 
  fine, 
  strongly 
  raised. 
  Axillae 
  not 
  touching. 
  On

  more 
  drawn 
  out 
  and 
  equally 
  raised. 
  Whole 
  mesonotum

   numerous 
  short

  upwards 
  of 
  30 
  (15-17 
  : 
  15-17) 
  stand 
  on 
  the 
  

   scutellum. 
  Metanotum 
  and 
  propodeon 
  rugulose 
  ; 
  pleurae 
  of 
  propodeon 
  beyond 
  the

  The

  at 
  the 
  side 
  of 
  the 
  tergites 
  are 
  much 
  less 
  numerous, 
  

   e.g., 
  in 
  the 
  second 
  tergite 
  only 
  two 
  such 
  cells 
  occur 
  on 
  each 
  side

  That 
  either 
  of 
  the 
  following 
  species 
  is 
  in 
  the 
  strict 
  sense 
  an 
  Encyrtus 
  is 
  debatable. 
  

   With 
  Andre's 
  species 
  I 
  have 
  no 
  direct 
  acquaintance, 
  and 
  so 
  have 
  left 
  it 
  as 
  the 
  author 
  

   placed 
  it. 
  E. 
  pidvinatus, 
  sp. 
  n., 
  differs 
  from 
  the 
  other 
  Encyrtus 
  spp. 
  known 
  to 
  me 
  

   mainly 
  in 
  its 
  type 
  of 
  colour 
  pattern, 
  somewhat 
  shorter 
  marginal 
  vein 
  and 
  its 
  mandibles. 
  

   It 
  may 
  represent 
  a 
  new 
  genus, 
  but 
  little 
  inconvenience 
  should 
  result 
  from 
  its 
  present 
  

   placing. 
  In 
  any 
  case 
  its 
  final 
  position 
  cannot 
  be 
  fixed 
  till 
  the 
  male 
  is 
  known.

  Andre 
  states 
  that 
  E. 
  triozae 
  is 
  an 
  internal 
  feeder 
  on 
  both 
  larvae 
  and 
  pupae, 
  but 
  

   to 
  the 
  description 
  itself 
  he 
  appends 
  merely 
  the 
  words 
  "

  ?. 
  A 
  dark 
  metallic 
  (?) 
  green 
  species, 
  with 
  conspicuously 
  pale 
  legs. 
  The 
  second 
  

   tergite 
  of 
  the 
  abdomen 
  is 
  characteristic. 
  Body 
  dark 
  green, 
  the 
  scutellum 
  matt. 
  

   Antennae 
  very 
  pale 
  brown, 
  a 
  little 
  darker 
  on 
  scape, 
  pedicel 
  (dorsally) 
  and 
  club. 
  

   Wings 
  faintly 
  but 
  completely 
  brown-tinted. 
  Fore 
  legs 
  (including 
  coxae) 
  entirely 
  

   pale, 
  except 
  for 
  the 
  fifth 
  tarsal 
  joint, 
  which 
  is 
  infuscated 
  as 
  in 
  the 
  mid 
  and 
  hind 
  

   legs 
  ; 
  mid 
  legs 
  pale 
  except 
  for 
  faintly 
  brown 
  coxa 
  and 
  fifth 
  joint 
  of 
  tarsus 
  ; 
  in 
  the 
  

   hind 
  legs 
  the 
  coxa 
  (except 
  near 
  the 
  trochanter) 
  and 
  the 
  distal 
  two-thirds 
  of 
  the 
  

   femur 
  are 
  brown, 
  the 
  rest 
  pale. 
  

  

  Note. 
  — 
  The 
  general 
  body 
  colour 
  may 
  have 
  altered 
  a 
  little 
  in 
  alcohol 
  but 
  it 
  appeared 
  

   to 
  be 
  mainly 
  dark 
  green. 
  The 
  clear 
  spot 
  between 
  the 
  marginal 
  and 
  submarginal 
  

   veins 
  is 
  indistinct.
