  the 
  species 
  introduced 
  into 
  Puerto 
  Rico 
  and 
  that 
  this 
  introduction 
  was 
  

   successful 
  even 
  though 
  the 
  species 
  introduced 
  was 
  not 
  the 
  one 
  intended. 
  

   Pseudaphycus 
  mundus 
  may 
  be 
  indigenous 
  in 
  Louisiana. 
  As 
  noted 
  

   above 
  it 
  was 
  reared 
  at 
  Audubon 
  Park, 
  New 
  Orleans, 
  as 
  early 
  as 
  1916, 
  at 
  

   least 
  16 
  years 
  prior 
  to 
  the 
  attempted 
  introduction 
  of 
  Aphycus 
  terryi. 
  

   Circumstantial 
  evidence 
  would 
  seem 
  to 
  indicate 
  that 
  in 
  the 
  attempt 
  to 
  

   increase 
  the 
  stock 
  of 
  the 
  Hawaiian 
  parasite 
  in 
  the 
  laboratory, 
  field- 
  

   collected 
  material 
  of 
  the 
  host 
  which 
  had 
  already 
  been 
  attacked 
  by 
  

   P. 
  mundiis 
  was 
  introduced 
  into 
  the 
  cages 
  and 
  the 
  two 
  species 
  thus 
  

   became 
  confused.

  PSEUDAPHYCUS 
  LDIATULUS,

  Bpceies 
  

  

  The 
  dorsum 
  of 
  the 
  thorax 
  in 
  this 
  species 
  is 
  more 
  weakly 
  sculptured, 
  

   more 
  distinctly 
  shining, 
  and 
  of 
  a 
  darker 
  yellowish-gray 
  color 
  than 
  in 
  

   any 
  of 
  the 
  other 
  species. 
  Most 
  closely 
  resembles 
  graminicola 
  but 
  

   distinguishable 
  by 
  the 
  above 
  characters 
  and 
  its 
  slightly 
  narrower 
  

   frontovertex.
