  appears 
  to 
  be 
  carnivorous, 
  and 
  was 
  probably 
  inhabiting 
  the 
  

   fungus 
  in 
  which 
  it 
  occurred 
  rather 
  plentifully 
  for 
  the 
  purpose 
  

   of 
  preying 
  upon 
  the 
  eggs 
  and 
  young 
  larvae 
  of 
  minute 
  animals, 
  

   which 
  the 
  peculiar 
  shape 
  of 
  its 
  head 
  would 
  enable 
  it 
  to 
  extract 
  

   from 
  the 
  cells 
  without 
  difficulty.

  Dimorphella 
  does 
  not 
  appear 
  to 
  be 
  intimately 
  allied 
  to 
  any 
  

   other 
  genus 
  ; 
  the 
  males 
  bear 
  some 
  resemblance 
  in 
  outward 
  

   form 
  to 
  Ptery 
  codes 
  and 
  the 
  females 
  to 
  Ptinella, 
  and 
  for 
  that 
  

   reason 
  it 
  should, 
  I 
  think, 
  be 
  placed 
  in 
  the 
  vicinity 
  of 
  one 
  or 
  

   other 
  of 
  those 
  genera.
