  The 
  San 
  Francisco 
  locality 
  (University 
  of 
  Ohio 
  collection) 
  is 
  prob- 
  

   ably 
  an 
  error 
  in 
  labeling, 
  or 
  an 
  accidental 
  transportation 
  of 
  specimens 
  

   from 
  the 
  southern 
  part 
  of 
  the 
  State. 
  

  

  Remarks. 
  — 
  This 
  is 
  the 
  most 
  variable 
  species 
  of 
  the 
  genus, 
  as 
  the 
  

   genital 
  structure 
  is 
  the 
  only 
  character 
  that 
  does 
  not 
  vary 
  tremen- 
  

   dously. 
  It 
  may 
  be 
  distinguished 
  easily 
  by 
  the 
  characters 
  given 
  in 
  the 
  

   key 
  when 
  it 
  has 
  been 
  placed 
  in 
  the 
  proper 
  group 
  by 
  the 
  genitalia 
  of 
  

   the 
  female.
