  A 
  distinct 
  species, 
  the 
  female 
  with 
  rather 
  the 
  aspect 
  of 
  a 
  male. 
  

   There 
  is 
  perhaps 
  some 
  affinity 
  with 
  N. 
  pampicola 
  Yar.flavescens 
  Friese, 
  

   very 
  briefly 
  described 
  from 
  Costa 
  Rica, 
  but 
  it 
  appears 
  not 
  to 
  be 
  

   identical.

  Female. 
  — 
  Length 
  about 
  7 
  mm.; 
  markings 
  pale 
  yellow, 
  consisting 
  of 
  

   lateral 
  face 
  marks, 
  narrow 
  above, 
  broad 
  below 
  and 
  curving 
  away 
  from 
  

   orbit, 
  a 
  spot 
  on 
  clypeus 
  (sometimes 
  absent), 
  upper 
  border 
  of 
  pronotum, 
  

   tubercles, 
  an 
  oval 
  spot 
  on 
  pleura, 
  nearly 
  all 
  of 
  scutellum, 
  postscutel- 
  

  

  more 
  numerous 
  ia 
  Mexico, 
  the 
  Caribbean 
  area, 
  and 
  Central 
  and 
  South 
  America. 
  The 
  group 
  may 
  prove 
  

   to 
  be 
  separable 
  from 
  Micronomada, 
  but 
  the 
  characters 
  by 
  which 
  it 
  might 
  be 
  distinguished 
  become 
  less 
  

   apparent 
  in 
  the 
  United 
  States. 
  Ideally 
  the 
  group 
  is 
  characterized 
  by 
  a 
  planing 
  of 
  the 
  face, 
  usually 
  with 
  

   sparse, 
  shallow 
  facial 
  punctures, 
  by 
  a 
  humpbacked 
  appearance 
  resulting 
  from 
  a 
  depression 
  of 
  the 
  mid- 
  

   dorsum 
  of 
  the 
  pronotum 
  which 
  is 
  overhung 
  by 
  the 
  middorsum 
  of 
  the 
  mesonotum, 
  by 
  the 
  spatulate 
  bristles 
  

   at 
  the 
  apex 
  of 
  the 
  hind 
  (often 
  the 
  middle) 
  tibiae, 
  and 
  by 
  the 
  darkening 
  of 
  the 
  costal, 
  rather 
  than 
  the 
  apical, 
  

   half 
  of 
  the 
  forewing. 
  They 
  do 
  not 
  seem 
  to 
  show 
  complete 
  uniformity 
  in 
  the 
  presence 
  of 
  anterior 
  coxal 
  spines, 
  

   in 
  the 
  degree 
  of 
  flattening 
  of 
  the 
  face, 
  or 
  the 
  density 
  of 
  facia! 
  punctures. 
  

  

  Cresson's 
  limata 
  from 
  Mexico 
  belongs 
  to 
  this 
  group. 
  The 
  outstanding 
  characters 
  of 
  the 
  type 
  are 
  the 
  dirty- 
  

   white 
  markings, 
  the 
  sparse 
  punctation 
  of 
  the 
  face 
  and 
  nearly 
  impunctate 
  shining 
  mesonotum, 
  the 
  flat 
  un- 
  

   lobed 
  scutellum, 
  expanded 
  coxae, 
  and 
  short 
  broad 
  scalelike 
  spines 
  at 
  the 
  apex 
  of 
  the 
  hind 
  tibiae.

  Nomada 
  limata 
  var. 
  xanthaspis 
  Cockerell 
  (9) 
  differs 
  from 
  limata 
  only 
  in 
  minor 
  characters 
  of 
  which 
  the 
  

   yellow, 
  rathei 
  than 
  white, 
  maculation 
  is 
  most 
  apparent. 
  Cockerell, 
  loc. 
  cit., 
  recorded 
  a 
  yellow 
  limata 
  from 
  

   Veracruz. 
  The 
  more 
  extensive 
  souteUar 
  spots 
  and 
  the 
  smaller 
  size 
  are 
  also 
  likely 
  to 
  be 
  within 
  the 
  range 
  of 
  

   specific 
  variation. 
  

  

  Nomada 
  zamoranica 
  Cockerell 
  (cf) 
  at 
  first 
  glance 
  might 
  be 
  assumed 
  to 
  be 
  the 
  undescribed 
  male 
  ot 
  limata. 
  

   It 
  differs 
  from 
  limata 
  in 
  the 
  strong 
  punctation 
  of 
  face 
  and 
  mesonotum, 
  in 
  the 
  protuberant 
  and 
  bilobed 
  scu- 
  

   tellum, 
  and 
  in 
  the 
  long, 
  slender 
  spines 
  of 
  the 
  anterior 
  coxae. 
  Whether 
  these 
  are 
  possibly 
  only 
  sexual 
  differ- 
  

   ences 
  must 
  be 
  decided 
  with 
  the 
  help 
  of 
  more 
  numerous 
  specimens 
  but 
  their 
  presence 
  in 
  the 
  related 
  female 
  

   specimen 
  next 
  discussed 
  suggests 
  that 
  they 
  are 
  real 
  specific 
  differences. 
  

  

  Nomada 
  hondurasica 
  Cockerell 
  ( 
  9 
  ) 
  is 
  also 
  superficially 
  very 
  similar 
  to 
  limata 
  but 
  differs 
  in 
  so 
  many 
  partic- 
  

   ulars 
  that 
  it 
  may 
  well 
  be 
  considered 
  a 
  separate 
  species. 
  It 
  is 
  more 
  extensively 
  marked 
  with 
  yellow 
  than 
  

   limata, 
  I. 
  xanthaspis, 
  or 
  zamoranica, 
  on 
  head, 
  thorax, 
  and 
  both 
  dorsum 
  and 
  sternum 
  of 
  the 
  abdomen. 
  The 
  

   strong 
  punctures 
  of 
  face 
  and 
  mesonotum, 
  the 
  prominent, 
  bilobed 
  scutellum, 
  and 
  the 
  long 
  slender 
  coxal 
  spines 
  

   are 
  like 
  those 
  of 
  zamoranica. 
  I 
  should 
  be 
  tempted 
  to 
  consider 
  this 
  the 
  female 
  of 
  zamoranica 
  if 
  it 
  were 
  not 
  

   for 
  the 
  fact 
  that 
  in 
  my 
  experience 
  males 
  are 
  likely 
  to 
  be 
  more 
  extensively 
  light-marked 
  than 
  the 
  females 
  of 
  

   the 
  same 
  species.
