  Head

   marked. 
  

  

  Antennae 
  (fig. 
  2, 
  b) 
  with 
  the 
  scape 
  flavescent, 
  six 
  times 
  as 
  long 
  as 
  broad, 
  not 
  swollen 
  

   near 
  the 
  apex. 
  Pedicel 
  more 
  than 
  a 
  third 
  of 
  the 
  scape 
  and 
  longer 
  than 
  broad 
  (5:3). 
  

   First 
  funicular 
  joint 
  a 
  little 
  broader 
  than 
  long, 
  and 
  shorter 
  than 
  the 
  second. 
  Joints 
  

   2 
  to 
  5 
  equal 
  and 
  quadrate, 
  the 
  sixth 
  hardly 
  shorter 
  and 
  also 
  quadrate 
  ; 
  club 
  

   distinctly 
  expanded, 
  with 
  sub-equal 
  segments 
  (17 
  : 
  16 
  : 
  15). 
  The 
  sensoria 
  of 
  the 
  

   funicle 
  and 
  club 
  are 
  more 
  numerous 
  in 
  the 
  $ 
  than 
  in 
  the

   The 
  pedicel 
  of 
  the 
  $ 
  antenna 
  is 
  also 
  broader 
  and 
  more 
  swollen 
  than 
  in 
  the

  Length 
  

   of 
  antenna, 
  -60 
  mm. 
  

  

  In 
  other 
  respects 
  the 
  $ 
  is 
  very 
  similar 
  in 
  dimensions, 
  colour, 
  etc., 
  to 
  the 
  <$. 
  

   Described 
  from 
  a 
  single 
  pair, 
  <J 
  and 
  $. 
  These 
  insects 
  were 
  bred 
  from 
  a 
  jak 
  fruit 
  

   (Artocarpus) 
  which 
  had 
  been 
  attacked 
  by 
  some 
  undetermined 
  insect. 
  

  

  Genus 
  Closterocerus, 
  Westw. 
  (1833). 
  

  

  To 
  this 
  genus 
  belong 
  some 
  of 
  the 
  most 
  beautiful 
  Entedonine 
  (Omphaline) 
  flies. 
  

   The 
  species 
  are 
  characterised 
  by 
  a 
  fine 
  refringent 
  sculpture 
  on 
  the 
  head 
  and 
  thorax, 
  

   by 
  their 
  exceedingly 
  brilliant 
  metallic 
  colour, 
  and 
  the 
  maculate 
  or 
  banded 
  fore 
  wings. 
  

   The 
  antennae 
  are 
  much 
  flattened 
  and 
  the 
  demarcation 
  between 
  club 
  and 
  funicle 
  is 
  

   hard 
  to 
  recognise. 
  Westwood 
  (Mag. 
  Nat. 
  Hist., 
  p. 
  419, 
  fig. 
  55c, 
  1833) 
  in 
  defining 
  the 
  

   genus 
  neither 
  mentions 
  nor 
  figures 
  a 
  ring 
  joint. 
  He 
  assigns 
  8 
  joints 
  to 
  the 
  genus, 
  

   remarking 
  that 
  the 
  last 
  is 
  " 
  very 
  minute 
  and 
  subulate 
  " 
  ; 
  apparently 
  he 
  ranked 
  as 
  a 
  

   joint 
  the 
  terminal 
  spur 
  of 
  the 
  seventh 
  visible 
  segment. 
  Girault's 
  account 
  (Mem. 
  

   Queensld. 
  Mus., 
  ii, 
  p. 
  177, 
  10th 
  Dec. 
  1913) 
  is 
  more 
  precise. 
  There 
  are 
  seven 
  apparent 
  

   segments 
  to 
  the 
  antennae, 
  or 
  eight 
  reckoning 
  the 
  tiny 
  ring 
  joint 
  which 
  is 
  practically 
  

   concealed 
  within 
  a 
  cavity 
  of 
  the 
  scape. 
  Similar 
  flattened 
  antennae 
  are 
  found 
  in 
  

   Neochrysocharis, 
  Kurdj. 
  (Revue 
  Russe 
  d'Ent., 
  xii, 
  no. 
  2, 
  p. 
  234, 
  fig. 
  3, 
  1912), 
  but 
  

   the 
  wings 
  in 
  this 
  genus 
  are 
  hyaline. 
  

  

  The 
  genus 
  Closterocer 
  us, 
  Westw., 
  is 
  at 
  present 
  a 
  small 
  one. 
  Schmiedeknecht 
  (Gen. 
  

   Ins. 
  Wytsman, 
  p. 
  428, 
  1909) 
  lists 
  11 
  species, 
  and 
  one 
  or 
  two 
  have 
  since 
  been 
  described 
  

   from 
  North 
  America, 
  Java 
  and 
  Australia. 
  Kurdjumov 
  (he. 
  cit., 
  p. 
  235) 
  points 
  out 
  

   that 
  besides 
  for 
  mosus, 
  Westw., 
  and 
  trifasciatus, 
  Westw., 
  Entedon 
  ovulorum, 
  Ratz., 
  

   should 
  be 
  placed 
  here. 
  There 
  are 
  therefore 
  at 
  least 
  three 
  European 
  forms. 
  Crawford 
  

   (Proc. 
  U.S. 
  Nat. 
  Mus., 
  xliii, 
  p. 
  175, 
  1913) 
  mentions 
  five 
  species 
  (one 
  doubtfully) 
  as
