  RemarTcs. 
  — 
  This 
  is 
  a 
  slight 
  form, 
  the 
  least 
  marked 
  of 
  any 
  recog- 
  

   nized. 
  Its 
  relationships 
  are 
  close 
  to 
  M. 
  v. 
  energumenos, 
  with 
  which 
  

   it 
  probably 
  blends 
  along 
  the 
  coast. 
  Though 
  specimens 
  from 
  the 
  

   Alaska 
  Peninsula 
  are 
  placed 
  with 
  ingens, 
  these 
  show 
  an 
  approach 
  

   toward 
  melampeplus.
