  Habitat. 
  — 
  The 
  female 
  type 
  comes 
  from 
  San 
  Miguel, 
  Peru, 
  where 
  

   it 
  was 
  collected 
  September 
  1, 
  at 
  an 
  elevation 
  of 
  5,000 
  feet 
  above 
  

   sea 
  level; 
  the 
  allotjrpe 
  was 
  taken 
  on 
  August 
  9, 
  at 
  Tincochaca, 
  at 
  

   7,000 
  feet 
  elevation. 
  Other 
  specimens, 
  immature 
  males 
  and 
  females, 
  

   are 
  at 
  hand 
  from 
  the 
  last-named 
  locality.

  URUBAMBA 
  INCONSPICUA, 
  new 
  species. 
  

  

  A 
  little 
  larger 
  and 
  more 
  robust 
  than 
  the 
  preceding 
  and 
  provided 
  

   with 
  coarsely 
  punctulate, 
  small, 
  lateral, 
  spatulate 
  tegmina 
  that 
  

   reach 
  the 
  apex 
  of 
  the 
  first 
  abdominal 
  segment. 
  This 
  insect 
  has 
  a 
  

   smoother 
  pronotum 
  than 
  U. 
  aptera 
  and 
  also 
  has 
  strong 
  lateral 
  carinae 
  

   on 
  the 
  pronotum. 
  Its 
  hind 
  femora 
  are 
  much 
  more 
  robust 
  and 
  lack 
  

   the 
  fuscous 
  bands 
  that 
  characteri* 
  the 
  species 
  with 
  which 
  com- 
  

   pared, 
  but 
  these 
  members 
  have 
  their 
  genicular 
  area 
  strongly 
  infus- 
  

   cated 
  instead.
