  Only 
  one 
  specimen 
  was 
  taken, 
  and 
  when 
  I 
  examined 
  it 
  I 
  did 
  not 
  

   know 
  what 
  genus 
  to 
  refer 
  it 
  to. 
  It 
  is 
  unique 
  by 
  the 
  largely 
  yellow 
  

   clypeus 
  of 
  the 
  female 
  and 
  the 
  fulvous 
  tomentum 
  of 
  the 
  abdomen 
  

   beyond 
  the 
  second 
  tergite; 
  the 
  abdomen 
  is 
  rather 
  long 
  and 
  narrow, 
  

   not 
  like 
  that 
  of 
  an 
  Exomalopsis. 
  When 
  both 
  sexes 
  are 
  loiown, 
  it 
  

   will 
  probably 
  be 
  referred 
  to 
  a 
  new 
  subgenus 
  or 
  genus. 
  Certainly 
  

   the 
  stigma 
  and 
  palpi 
  are 
  not 
  like 
  those 
  of 
  Exomalopsis.

  Upon 
  his 
  return 
  from 
  Honduras 
  in 
  1947, 
  Professor 
  Cockerell 
  described 
  four 
  specimens 
  of 
  Nomada, 
  col- 
  

   lected 
  at 
  Zamorano, 
  Honduras. 
  He 
  then 
  turned 
  the 
  specimens 
  over 
  to 
  me 
  with 
  the 
  request 
  that 
  I 
  make 
  

   such 
  comments 
  upon 
  them 
  as 
  might 
  seem 
  appropriate, 
  these 
  comments 
  to 
  be 
  included 
  with 
  his 
  manuscript. 
  

  

  Three 
  of 
  the 
  specimens 
  were 
  described 
  as 
  types 
  of 
  new 
  species 
  and 
  the 
  fourth 
  as 
  a 
  variety 
  of 
  a 
  previously 
  

   described 
  species 
  of 
  E. 
  T. 
  Cresson. 
  I 
  am 
  not 
  in 
  a 
  position 
  to 
  comment 
  on 
  N. 
  tenvicornis, 
  as 
  it 
  is 
  the 
  first 
  

   non-MicTonomada 
  specimen 
  from 
  outside 
  the 
  limits 
  of 
  the 
  United 
  States 
  I 
  have 
  had 
  occasion 
  to 
  examine. 
  

  

  The 
  two 
  remaining 
  new 
  species 
  and 
  the 
  new 
  variety 
  may 
  be 
  assigned 
  provisionally 
  to 
  the 
  subgenus 
  

   Mkronomada. 
  Although 
  not 
  all 
  of 
  them 
  have 
  "strong 
  coxal 
  spines" 
  on 
  the 
  front 
  coxae, 
  they 
  are 
  somehow 
  

   allied 
  to 
  Mkronomada 
  as 
  constituted 
  in 
  North 
  America. 
  They, 
  with 
  Cresson's 
  limata, 
  several 
  unidentified 
  

   Caribbean 
  specimens 
  that 
  I 
  have 
  examined 
  in 
  various 
  collections, 
  and 
  some 
  species 
  described 
  from 
  South 
  

   America, 
  seem 
  to 
  form 
  a 
  group 
  of 
  species 
  represented 
  vaguely 
  in 
  the 
  United 
  States 
  but 
  apparently 
  much
