﻿The 
  British

  Hants, 
  Dorset, 
  Devon 
  and 
  Glamorgan, 
  and 
  no 
  doubt 
  in 
  

   other 
  counties, 
  but 
  it 
  is 
  always 
  local. 
  Sometimes 
  it 
  is 
  

   very 
  abundant, 
  as 
  on 
  one 
  occasion 
  eighteen 
  years 
  ago, 
  

   on 
  the 
  border 
  of 
  Suffolk 
  and 
  Cambridge, 
  when 
  I 
  found 
  a 
  

   bank 
  grown 
  over 
  with 
  scabious 
  with 
  nearly 
  every 
  flower 
  

   occupied 
  and 
  often 
  two 
  or 
  three 
  bees 
  on 
  a 
  single 
  blossom. 
  

   All 
  our 
  colour 
  varieties 
  were 
  present, 
  but 
  no 
  trace 
  of 
  

   any 
  parasites 
  was 
  found. 
  In 
  Devon 
  I 
  have 
  not 
  found 
  

   highly 
  coloured 
  specimens, 
  but 
  they 
  occur 
  freely 
  in 
  Dorset. 
  

   Nomada 
  argentata, 
  a 
  very 
  local 
  and 
  generally 
  rare 
  species, 
  

   is 
  the 
  special 
  parasite 
  of 
  marginata, 
  but 
  it 
  has 
  only 
  been 
  

   recorded 
  from 
  a 
  few 
  localities, 
  in 
  Surrey, 
  Sussex, 
  Berkshire 
  

   and 
  Kent. 
  

  

  A. 
  cingidata 
  is 
  a 
  widely 
  distributed 
  bee, 
  probably 
  to 
  be 
  

   found 
  in 
  nearly 
  all 
  the 
  more 
  southern 
  counties 
  at 
  least, 
  

   and 
  it 
  also 
  occurs 
  in 
  the 
  north 
  of 
  England, 
  but 
  is 
  by 
  no 
  

   means 
  always 
  common. 
  It 
  not 
  only 
  frequents 
  sandy 
  

   commons, 
  but 
  is 
  also 
  partial 
  to 
  well-cultivated 
  districts 
  

   and 
  is 
  found 
  high 
  up 
  in 
  hilly 
  districts, 
  e.g., 
  the 
  Cotswolds 
  

   and 
  Dorsetshire 
  hills. 
  It 
  used 
  to 
  be 
  extremely 
  abundant 
  

   in 
  suburban 
  localities, 
  and 
  this 
  probably 
  led 
  to 
  its 
  being 
  

   considered 
  a 
  much 
  commoner 
  species 
  than 
  is 
  really 
  the 
  

   case. 
  Thus 
  Shuckard 
  makes 
  the 
  obviously 
  very 
  erroneous 
  

   statement, 
  that 
  it 
  is 
  perhaps 
  the 
  commonest 
  species 
  of 
  the 
  

   whole 
  genus 
  ! 
  In 
  several 
  extensive 
  districts, 
  where 
  I 
  

   have 
  collected, 
  it 
  occurs 
  very 
  sparingly 
  and 
  even 
  rarely. 
  

   In 
  some 
  it 
  forms 
  large 
  colonies, 
  but 
  these 
  are 
  generally 
  

   local. 
  All 
  observers 
  note 
  its 
  attachment 
  to 
  the 
  flowers 
  of 
  

   Veronica, 
  but 
  the 
  female 
  sometimes 
  collects 
  pollen 
  from 
  

   the 
  dandelion 
  and 
  the 
  common 
  buttercup, 
  and 
  the 
  males 
  

   also 
  visit 
  these. 
  

  

  Kirby 
  records 
  that 
  he 
  took 
  the 
  females 
  on 
  Ranunculus 
  

   bulbosus 
  in 
  May, 
  but 
  his 
  statement 
  that 
  the 
  males 
  occur 
  

   in 
  the 
  autumn 
  must 
  be 
  an 
  error, 
  and 
  (although, 
  of 
  course, 
  

   he 
  knew 
  this 
  sex 
  well) 
  may 
  perhaps 
  be 
  due 
  to 
  some 
  

   momentary 
  confusion 
  between 
  this 
  and 
  the 
  males 
  of 
  

   Sphecodes. 
  Hallett 
  found 
  this 
  bee 
  abundantly 
  on 
  Auhretia 
  

   in 
  a 
  garden. 
  Of 
  very 
  wide 
  distribution, 
  but 
  apparently 
  

   nearly 
  always 
  rare, 
  is 
  its 
  special 
  parasite 
  Nomada 
  guttu- 
  

   lata; 
  but 
  as 
  this 
  occurs 
  in 
  suburban 
  locaUties, 
  in 
  the 
  

   eastern 
  comities, 
  and 
  so 
  far 
  west 
  as 
  Devonshire, 
  it 
  may 
  

   reasonably 
  (being 
  an 
  obscure 
  little 
  species) 
  be 
  expected 
  

   to 
  occur, 
  if 
  specially 
  searched 
  for, 
  in 
  many 
  locaUties, 
  where 
  

   the 
  host 
  thrives. 
  Kirby 
  described 
  the 
  $ 
  as 
  a 
  variety 
  of
