  Mr. 
  R. 
  C. 
  L. 
  Perkins 
  on 
  

  

  cated, 
  published 
  records 
  are 
  of 
  little 
  value, 
  owing 
  to 
  frequent 
  

   misidentification. 
  Smith's 
  supposed 
  Scotch 
  specimens 
  are 
  

   a 
  mixture 
  of 
  A 
  . 
  praecox 
  and 
  synadelpha. 
  

  

  It 
  is, 
  I 
  think, 
  certainly 
  parasitised 
  by 
  Nomada 
  ruficornis, 
  

   but 
  I 
  have 
  not 
  seen 
  a 
  stylopised 
  example, 
  though 
  these 
  

   probably 
  occur. 
  

  

  A. 
  synadeljjha 
  is 
  a 
  very 
  widely 
  distributed 
  species, 
  but 
  

   local. 
  It 
  occurs 
  in 
  many 
  of 
  the 
  southern 
  counties, 
  and 
  also 
  

   in 
  Scotland. 
  The 
  $ 
  frequents 
  the 
  dandelion, 
  hawthorn, 
  wild 
  

   rose 
  and 
  other 
  flowers, 
  and 
  was 
  taken 
  in 
  numbers 
  together 
  

   by 
  Morice 
  on 
  Sisymbrium 
  alliaria. 
  

  

  It 
  is 
  very 
  much 
  parasitised 
  by 
  Nomada 
  ruficornis 
  s.s., 
  but 
  

   is 
  rarely 
  stylopised. 
  The 
  variation 
  in 
  the 
  $ 
  is 
  somewhat 
  

   similar 
  to 
  that 
  of 
  varians, 
  but 
  less 
  extreme. 
  

  

  A.fucata 
  is 
  one 
  of 
  the 
  most 
  widely 
  distributed 
  of 
  all 
  our 
  

   bees, 
  being 
  common 
  in 
  the 
  north 
  of 
  England 
  and 
  in 
  Scotland, 
  

   and 
  also 
  in 
  many 
  parts 
  of 
  the 
  west 
  of 
  England 
  and 
  in 
  Ireland. 
  

   It 
  also 
  occurs, 
  sometimes 
  not 
  rarely, 
  in 
  the 
  more 
  eastern 
  

   counties, 
  in 
  Suffolk, 
  Hampshire 
  and 
  Surrey, 
  also 
  in 
  Oxford- 
  

   shire 
  and 
  Warwickshire, 
  and 
  on 
  a 
  very 
  unfavourable 
  and 
  

   stormy 
  day 
  I 
  observed 
  it 
  in 
  some 
  nmnbers 
  in 
  Bricket 
  Wood, 
  

   Herts, 
  Probably 
  it 
  is 
  to 
  be 
  found 
  in 
  nearly 
  every 
  county, 
  

   but 
  in 
  many 
  localities 
  it 
  is 
  only 
  seen 
  in 
  small 
  numbers. 
  

   Where 
  it 
  frequents 
  gardens, 
  the 
  females 
  are 
  sure 
  to 
  be 
  found 
  

   gathering 
  their 
  pollen 
  from 
  the 
  raspberry 
  flowers 
  ; 
  on 
  wild 
  

   heaths 
  or 
  moorland 
  it 
  frequents 
  the 
  Potentilla 
  in 
  preference 
  

   to 
  any 
  other 
  plant, 
  excepting 
  perhaps 
  Vaccinium 
  in 
  some 
  

   localities. 
  Sometimes 
  it 
  may 
  be 
  taken 
  freely 
  on 
  Crataegus 
  

   and 
  the 
  wild 
  rose, 
  and 
  late 
  examples 
  on 
  Ruhus. 
  It 
  is 
  nor- 
  

   mally 
  on 
  the 
  wing 
  in 
  May 
  in 
  Devonshire, 
  but 
  in 
  some 
  counties 
  

   not 
  usually 
  until 
  June, 
  or 
  even 
  July 
  in 
  the 
  north. 
  I 
  have 
  

   never 
  come 
  across 
  a 
  large 
  colony 
  of 
  this 
  species, 
  but 
  I 
  once 
  

   found 
  a 
  small 
  one 
  of 
  about 
  a 
  dozen 
  burrows 
  placed 
  close 
  

   together. 
  

  

  I 
  beheve 
  that 
  this 
  bee 
  is 
  parasitised 
  by 
  Nomada 
  ruficornis 
  

   S.S., 
  since 
  I 
  have 
  taken 
  the 
  latter 
  in 
  places 
  where 
  I 
  could 
  find 
  

   no 
  other 
  member 
  of 
  the 
  varians 
  group. 
  Occasionally, 
  but 
  

   quite 
  rarely, 
  stylopised 
  individuals 
  are 
  met 
  with. 
  

  

  A. 
  lapponica 
  is 
  an 
  extremely 
  local 
  species 
  in 
  the 
  south, 
  and 
  

   can 
  only 
  be 
  expected 
  where 
  there 
  is 
  a 
  good 
  growth 
  of 
  

   Vaccinium, 
  since, 
  so 
  far 
  as 
  my 
  limited 
  experience 
  goes, 
  the 
  

   $ 
  collects 
  its 
  pollen 
  only 
  from 
  this. 
  The 
  male 
  is 
  said 
  to 
  

   visit 
  other 
  plants, 
  and 
  in 
  moorland 
  locahties 
  is 
  fond 
  of 
  flying 
  

   round 
  or 
  setthng 
  on 
  rocks. 
  The 
  burrows 
  that 
  I 
  have 
  seen
