  This 
  species 
  was 
  reared 
  by 
  Dr. 
  Smiih 
  from 
  mushrooms. 
  

  

  The 
  specimens 
  reared 
  by 
  him 
  from 
  decaying 
  potatoes 
  resemble 
  the 
  

   preceding 
  species 
  in 
  many 
  ways; 
  however, 
  on 
  further 
  study 
  it 
  was 
  found 
  

   to 
  be 
  quite 
  distinct. 
  Its 
  description 
  follows:
