  Issororo, 
  N.W. 
  district, 
  ix.1921, 
  bred 
  from 
  larvae 
  inhabiting 
  

   bases 
  of 
  pineapple 
  plant 
  ;

  2

  bred 
  from

   bromelias. 
  

  

  The 
  only 
  described 
  species 
  which 
  seems 
  to 
  be 
  nearly 
  allied 
  to 
  this 
  is 
  W. 
  aphobema, 
  

   Dyar, 
  in 
  which 
  the 
  male 
  claspers 
  are 
  much 
  more 
  slender, 
  and 
  which 
  probably 
  differs 
  

   also 
  in 
  the 
  structure 
  of 
  its 
  middle 
  feet. 
  

  

  Wyeomyia

  2$, 
  Issororo, 
  ix.1921, 
  bred 
  from 
  larvae 
  inhabiting 
  bases 
  of 
  leaves 
  of 
  pineapple 
  

   plant, 
  associated 
  with 
  W. 
  bodkini, 
  sp. 
  n., 
  and 
  W. 
  telestica, 
  D. 
  & 
  K. 
  

  

  The 
  coloration 
  of 
  these 
  examples 
  is 
  almost 
  precisely 
  as 
  in 
  W. 
  bodkini, 
  which 
  I 
  

   at 
  first 
  took 
  to 
  be 
  merely 
  a 
  form 
  of 
  W. 
  aphobema 
  ; 
  but 
  the 
  male 
  hypopygium 
  differs 
  

   distinctly 
  and 
  agrees 
  fairly 
  well 
  with 
  Dyar's 
  description 
  and 
  subsequent 
  figure. 
  

   According 
  to 
  Dyar's 
  description 
  the 
  mid-tarsi 
  are 
  white 
  beneath, 
  but 
  this 
  is 
  perhaps 
  

   an 
  error, 
  since 
  in 
  the 
  specimens 
  before 
  me 
  the 
  white 
  on 
  the 
  mid 
  tarsi 
  extends 
  almost 
  

   all 
  round, 
  but 
  leaves 
  a 
  narrow 
  dark 
  line 
  beneath, 
  as 
  in 
  W. 
  bodkini. 
  The 
  male 
  claspers 
  

   apparently 
  bear 
  only 
  three 
  fine 
  hairs 
  and 
  only 
  two 
  minute 
  terminal 
  spines. 
  

  

  The 
  last 
  mid 
  tarsal 
  segment 
  (fig. 
  1, 
  a) 
  is 
  only 
  a 
  little 
  over 
  twice 
  as 
  long 
  as 
  its 
  

   greatest 
  breadth, 
  and 
  bears 
  four 
  small 
  spines 
  in 
  the 
  middle 
  beneath 
  ; 
  its 
  claws 
  are 
  

   very 
  unequal, 
  the 
  larger 
  one 
  strongly 
  curved, 
  sickle-shaped.

  $. 
  Closely 
  allied 
  to 
  A. 
  simpsoni, 
  Theo., 
  differing 
  only 
  in 
  mesonotal 
  ornamentation, 
  

   as 
  follows 
  : 
  — 
  The 
  white 
  patch 
  on 
  the 
  anterior 
  margin 
  is 
  smaller 
  and 
  composed 
  of 
  

   narrower 
  scales. 
  The 
  two 
  main 
  white 
  patches 
  are 
  much 
  smaller, 
  rather 
  narrowly 
  

   crescent-shaped, 
  almost 
  as 
  in 
  A. 
  argenteus. 
  The 
  two 
  admedian 
  golden 
  lines 
  are 
  

   more 
  evident 
  than 
  is 
  usual 
  in 
  A. 
  simpsoni, 
  and 
  run 
  distinctly 
  the 
  whole 
  length 
  of 
  

   the 
  mesonotum. 
  The 
  pair 
  of 
  shorter 
  lines 
  in 
  front 
  of 
  the 
  scutellum 
  are 
  golden 
  

   instead 
  of 
  white, 
  and 
  composed 
  of 
  very 
  narrow 
  scales. 
  The 
  scutelhnn 
  has 
  white 
  

   scales 
  on 
  the 
  median 
  lobe, 
  black 
  scales 
  on 
  the 
  lateral 
  lobes.
