  The 
  synonymy 
  given 
  above 
  is, 
  I 
  believe, 
  correct, 
  the 
  determination 
  being 
  based 
  

   upon 
  an 
  examination 
  of 
  material 
  received 
  from 
  both 
  Morgan 
  and 
  Maskell. 
  A 
  co-type 
  

   $ 
  from 
  Morgan 
  in 
  my 
  collection 
  was 
  originally 
  mounted 
  in 
  Canada 
  balsam 
  without 
  

   staining, 
  so 
  that 
  the 
  true 
  form 
  of 
  the 
  strikingly 
  characteristic 
  squamae 
  on 
  the 
  

   pygidium 
  of 
  the 
  $ 
  could 
  not 
  be 
  detected 
  and 
  was 
  thus 
  overlooked 
  by 
  Morgan 
  in 
  the 
  

   first 
  instance, 
  and 
  subsequently 
  also 
  by 
  Leonardi, 
  to 
  whom 
  I 
  sent 
  my 
  example 
  for 
  

   examination, 
  and 
  for 
  the 
  purpose 
  also 
  of 
  figuring 
  it 
  in 
  his 
  memoir 
  (I.e.). 
  In 
  1906 
  I 
  

   had 
  occasion 
  to 
  stain 
  the 
  female 
  given 
  to 
  me 
  by 
  Morgan 
  for 
  comparison 
  with 
  examples 
  

   submitted 
  to 
  me 
  by 
  Kotinsky, 
  on 
  Ficus 
  sp., 
  from 
  Honolulu. 
  I 
  then 
  found 
  that 
  the 
  

   squamae 
  were 
  strikingly 
  different 
  from 
  what 
  they 
  appeared 
  to 
  be 
  when 
  unstained. 
  

   Subsequently 
  I 
  stained 
  and 
  mounted 
  an 
  example 
  of 
  Maskell's 
  A. 
  longispina 
  var. 
  

   omata 
  and 
  found 
  it 
  to 
  be 
  specifically 
  identical 
  with 
  Morgan's 
  co-type 
  female. 
  Clearly 
  

   therefore 
  the 
  specific 
  names 
  maskelli 
  of 
  Cockerell 
  and 
  omata 
  of 
  Maskell 
  must 
  sink.
