  with 
  three 
  pairs 
  of 
  long 
  hairs, 
  those 
  of 
  the 
  anterior 
  pair, 
  however, 
  are 
  often 
  consider- 
  

   ably 
  shorter 
  than 
  the 
  others 
  ; 
  one 
  or 
  two 
  pairs 
  of 
  exceedingly 
  minute 
  and 
  incon- 
  

   spicuous 
  hairs 
  may 
  also 
  be 
  present 
  on 
  this 
  shield, 
  in 
  addition 
  to 
  the 
  long 
  ones. 
  

   Between 
  these 
  two 
  principal 
  shields 
  there 
  are 
  two 
  pairs 
  of 
  minute 
  intermediate 
  plate- 
  

   lets, 
  those 
  of 
  the 
  anterior 
  pair 
  being 
  the 
  larger 
  ; 
  there 
  are 
  three 
  central 
  pairs 
  of 
  hairs 
  

   on 
  this 
  unprotected 
  part 
  of 
  the 
  dorsal 
  surface, 
  the 
  first 
  pair 
  being 
  placed 
  between 
  

   the 
  anterior 
  pair 
  of 
  intermediate 
  platelets 
  ; 
  lateral 
  hairs 
  are 
  also 
  present. 
  There 
  

   is 
  a 
  minute 
  platelet 
  in 
  front 
  of 
  the 
  anterior 
  end 
  of 
  the 
  peritreme 
  and 
  another 
  more

  The 
  description 
  of 
  the 
  male 
  of 
  Leiognathus 
  bacoti 
  is 
  based 
  on 
  Australian 
  specimens, 
  

   no 
  others 
  being 
  available, 
  but 
  females 
  and 
  nymphs 
  from 
  Egypt, 
  Australia, 
  and 
  South 
  

   America 
  have 
  been 
  carefully 
  compared 
  with 
  one 
  another 
  ; 
  I 
  cannot 
  find 
  any 
  difference 
  

   between 
  examples 
  from 
  these 
  widely 
  separated 
  localities.
