  I 
  was 
  at 
  first 
  in 
  doubt 
  whether 
  to 
  refer 
  this 
  to 
  H. 
  desertus 
  Smith, 
  

   but 
  the 
  polished 
  scutellum 
  is 
  distinctive. 
  At 
  the 
  British 
  Museum 
  I 
  

   examined 
  the 
  type 
  of 
  H. 
  desertus, 
  and 
  made 
  the 
  following 
  notes: 
  

  

  H. 
  desertus. 
  Hind 
  spur 
  serrate; 
  second 
  and 
  third 
  submarginal 
  cells 
  very 
  broad, 
  

   third 
  without 
  any 
  distinct 
  double 
  curve 
  on 
  outer 
  margin; 
  area 
  of 
  metathorax 
  

   merely 
  minutely 
  granular. 
  Looks 
  much 
  like 
  H. 
  coriaceus 
  or 
  politus, 
  but 
  is 
  

   smaller; 
  stigma 
  brown, 
  not 
  nearly 
  so 
  yellow, 
  wings 
  not 
  yellow 
  hke 
  politus.

  conspicuously 
  

   punctured, 
  shining; 
  lower 
  part 
  of 
  supraclypeal 
  area 
  with 
  a 
  polished 
  

   space, 
  but 
  face 
  and 
  front 
  otherwise 
  dull; 
  eyes 
  of 
  the 
  Halictus 
  type; 
  

   thorax 
  dullish, 
  median 
  groove 
  of 
  mesonotum 
  very 
  distinct; 
  scutellum 
  

   with 
  two 
  shining 
  spaces; 
  area 
  of 
  metathorax 
  bluer 
  than

   with 
  a 
  thick 
  rim; 
  tegulae 
  small, 
  shining 
  black;

  greenish.

  There 
  is 
  some 
  resemblance 
  to 
  H. 
  nigroaeneus 
  Friese, 
  but 
  the 
  blue 
  

   color 
  of 
  head 
  and 
  thorax 
  is 
  distinctive. 
  The 
  blue 
  color 
  separates 
  it 
  

   also 
  from 
  H. 
  cyanicoUis 
  Friese.
