  Although 
  Thomas's 
  description 
  of 
  G. 
  yarroioii 
  was 
  based 
  upon 
  a 
  

   female 
  only, 
  I 
  am 
  tolerably 
  confident 
  that 
  this 
  species 
  is 
  to 
  be 
  referred 
  

   to 
  it; 
  it 
  certainly 
  fits 
  it 
  better 
  than 
  any 
  known 
  to 
  me, 
  and 
  its 
  reference 
  

   here 
  was 
  suggested 
  to 
  me 
  by 
  Professor 
  Bruner. 
  Thomas 
  gave 
  no 
  locality 
  

   beyond 
  "found 
  in 
  the 
  collection," 
  which 
  was 
  made 
  in 
  "portions 
  of 
  

   IS'evada, 
  Utah, 
  California, 
  Colorado, 
  New 
  Mexico 
  and 
  Arizona." 
  He 
  

   afterwards 
  mentions 
  it 
  as 
  " 
  probably 
  from 
  Arizona, 
  but 
  possibly 
  from 
  

   Nevada," 
  without 
  giving 
  reasons. 
  From 
  all 
  that 
  appears 
  it 
  might 
  have 
  

   come 
  as 
  well 
  from 
  Colorado 
  or 
  Utah.
