  One 
  female. 
  Arizona, 
  G. 
  W. 
  Dunn 
  (L. 
  Bruner). 
  It 
  was 
  originally 
  

   described 
  from 
  southern 
  Arizoua. 
  

  

  I 
  have 
  here 
  adhered 
  to 
  my 
  original 
  limitation 
  ^ 
  of 
  Thomas's 
  species, 
  

   although 
  I 
  was 
  mistaken 
  in 
  supposing 
  that 
  the 
  male 
  I 
  then 
  had 
  before 
  

   me 
  was 
  one 
  of 
  those 
  used 
  by 
  him 
  in 
  his 
  description, 
  since 
  he 
  describes 
  

   the 
  cerci 
  as 
  enlarged 
  at 
  the 
  extremity, 
  which 
  they 
  certainly 
  were 
  not 
  

   in 
  the 
  one 
  then 
  in 
  my 
  hands. 
  Thomas's 
  originals, 
  so 
  far 
  as 
  now 
  i)re- 
  

   served 
  in 
  the 
  ]S"ational 
  Museum, 
  all 
  belong 
  to 
  my 
  Met. 
  aridus, 
  but 
  for- 
  

   tunately 
  a 
  specimen 
  in 
  Professor 
  Bruner's 
  collection, 
  altbough 
  it 
  is 
  

   only 
  a 
  female, 
  enables 
  me 
  to 
  fix 
  the 
  species. 
  It 
  may 
  be 
  separated 
  from 
  

   3Iel. 
  aridus 
  by 
  the 
  character 
  which 
  Thomas 
  describes 
  thus: 
  "Posterior 
  

   margin 
  [of 
  pronotum] 
  truncate 
  on 
  the 
  back 
  [i. 
  e., 
  disk], 
  or 
  curved 
  

   slightly 
  forward" 
  [i. 
  e., 
  emarginate], 
  the 
  posterior 
  margin 
  in 
  Jlel. 
  andus 
  

   being 
  distinctly 
  obtusangulate, 
  though 
  subtruncate.
