  One 
  specunen 
  collected 
  by 
  Prof. 
  C. 
  R. 
  Crosby 
  on 
  May 
  23, 
  1923. 
  

   It 
  gives 
  me 
  great 
  pleasure 
  to 
  name 
  this 
  species 
  after 
  the 
  late 
  Professor 
  

   Crosby. 
  This 
  is 
  but 
  one 
  of 
  the 
  many 
  interesting 
  new 
  species 
  that 
  he 
  

   collected 
  and 
  sent 
  to 
  me 
  for 
  study.
