  A 
  very 
  distinct 
  species 
  with 
  no 
  close 
  ally. 
  The 
  coloration 
  is 
  rather 
  suggestive 
  

   of 
  the 
  Canadian 
  Aides 
  (Odder 
  otatus) 
  spencer 
  i, 
  but 
  the 
  presence 
  of 
  spiracular 
  bristles 
  

   and 
  the 
  simple 
  claws 
  show 
  that 
  the 
  insect 
  is 
  a 
  Psorophora 
  of 
  the 
  subgenus 
  Grabhamia. 
  

   The 
  small 
  size 
  of 
  the 
  mesonotal 
  scales 
  is 
  noteworthy.
