   upon 
  rubber 
  (Castilloa) 
  from 
  Nicaragua, 
  C. 
  America. 
  This 
  

   species 
  is 
  even 
  more 
  closely 
  allied 
  to 
  palmae 
  than 
  is 
  rapax, 
  and 
  

   were 
  the 
  determination 
  made 
  by 
  a 
  worker 
  less 
  careful 
  than 
  Mr. 
  

   Newstead 
  one 
  would 
  be 
  inclined 
  to 
  doubt 
  the 
  authenticity 
  of 
  the 
  

   name. 
  A. 
  cydojiiae 
  and 
  its 
  var., 
  crawii, 
  are 
  quite 
  common 
  on 
  

   these 
  islands 
  as 
  is 
  also 
  a 
  variety 
  of 
  rubber 
  trees 
  but 
  so 
  far 
  this 
  

   species 
  has 
  not 
  been 
  reported

  thorax 
  separated

  third,
