  the 
  processes 
  on 
  the 
  fourth 
  and 
  fifth 
  sternites. 
  To 
  the 
  four 
  species 
  

   which 
  I 
  Hsted 
  in 
  the 
  place 
  cited, 
  C. 
  serripes 
  Ducke 
  is 
  to 
  be 
  added. 
  

   This 
  species, 
  described 
  in 
  both 
  sexes, 
  is 
  considerably 
  smaller 
  than 
  our 
  

   insect. 
  The 
  hind 
  tibiae 
  of 
  the 
  male 
  are 
  strongly 
  serrate 
  on 
  outer 
  side, 
  

   which 
  is 
  not 
  at 
  all 
  true 
  of 
  C. 
  uyacanus. 
  Eventually, 
  perhaps, 
  C. 
  

   uyacanus 
  will 
  be 
  assigned 
  to 
  a 
  new 
  genus 
  to 
  which 
  C. 
  sicheli 
  (Aga- 
  

   postemon 
  sicheli) 
  of 
  Vachal 
  will 
  be 
  added. 
  I 
  saw 
  a 
  specimen 
  of 
  C. 
  

   sicheli 
  in 
  the 
  British 
  Museum; 
  it 
  has 
  the 
  clypeus 
  yellowish 
  white 
  

   except 
  upper 
  margin; 
  labrum 
  yellowish 
  white.

  HALICTUS 
  LIGATUS 
  TOWNSENDI 
  Cockerell 
  

  

  Female. 
  — 
  A 
  black 
  form 
  with 
  a 
  very 
  large 
  head, 
  on 
  the 
  under 
  side 
  

   of 
  which 
  are 
  two 
  short 
  spines. 
  

  

  Male. 
  — 
  Head 
  not 
  enlarged; 
  a 
  yellow 
  band 
  on 
  clypeus. 
  

  

  Honduras: 
  Common 
  at 
  Zamorano. 
  Many 
  years 
  ago 
  I 
  described 
  

   this 
  as 
  H. 
  townsendi 
  from 
  Mexico, 
  but 
  Miss 
  Sandhouse, 
  in 
  her 
  revi- 
  

   sion, 
  considered 
  it 
  a 
  synonym 
  of 
  the 
  cormnon 
  H. 
  ligatus 
  of 
  the 
  United 
  

   States. 
  In 
  my 
  opinion 
  it 
  is 
  a 
  valid 
  subspecies, 
  but 
  it 
  is 
  closely 
  allied 
  

   to 
  the 
  form 
  from 
  Florida 
  described 
  by 
  F. 
  Smith 
  (1853) 
  as 
  H. 
  capitosus. 
  

   I 
  have 
  no 
  material 
  from 
  Florida 
  for 
  comparison.

  Compared 
  with 
  H. 
  pseudovagans, 
  this 
  is 
  conspicuously 
  less 
  bulky, 
  

   with 
  a 
  much 
  narrower 
  abdomen. 
  I 
  took 
  it 
  in 
  November 
  at 
  flowers 
  

   of 
  Baltimora

  A 
  male 
  was 
  obtained 
  February

  It
