  rather 
  later 
  in 
  appearance 
  in 
  the 
  spring 
  than 
  A. 
  parvula. 
  

   The 
  variabihty 
  to 
  which— 
  apart 
  from 
  that 
  due 
  to 
  seasonal 
  

   dimorphism 
  — 
  both 
  species 
  are 
  subject, 
  sometimes 
  makes 
  

   them 
  difficult 
  to 
  separate, 
  but 
  minutuloides 
  occurs 
  in 
  Surrey, 
  

   Kent, 
  Suffolk 
  and 
  Devonshire, 
  and, 
  doubtless, 
  in 
  many 
  

   other 
  counties, 
  but 
  I 
  have 
  seen 
  none 
  from 
  the 
  north, 
  

  

  A. 
  dorsata 
  in 
  the 
  wilkella 
  group 
  is 
  a 
  local 
  bee, 
  which 
  one 
  

   would 
  expect 
  to 
  occur 
  in 
  Scotland, 
  unless 
  it 
  were 
  there 
  

   replaced 
  by 
  the 
  veTy 
  similar 
  A. 
  propinqua 
  of 
  N.W. 
  Europe, 
  

   a 
  species 
  (or 
  ? 
  race) 
  with 
  similar 
  habits 
  ; 
  but 
  I 
  have 
  seen 
  

   no 
  Scotch 
  examples. 
  It 
  is 
  reg-ularly 
  double-brooded, 
  the 
  

   first 
  generation 
  frequenting 
  Salix 
  and 
  blackthorn, 
  but 
  also 
  

   many 
  other 
  plants, 
  I 
  have 
  taken 
  it 
  in 
  abundance 
  on 
  

   daisies 
  and 
  Brassica, 
  gathering 
  pollen 
  from 
  these 
  ; 
  also 
  on 
  

   Veronica, 
  Ruhus 
  idaeus, 
  fruit-trees 
  and 
  dandelions, 
  and 
  

   late 
  examples 
  on 
  white 
  Umbelliferae. 
  The 
  second 
  brood 
  

   occurs 
  on 
  Rubus, 
  yellow 
  Composites, 
  daisies 
  and 
  Melilohis, 
  

   and 
  sometimes 
  on 
  ragwort 
  and 
  PotentiUa. 
  Saunders 
  

   mentions 
  br3^ony 
  as 
  a 
  flower 
  visited 
  by 
  this 
  brood, 
  and 
  

   Mr. 
  Morice 
  informs 
  me 
  that 
  it 
  is 
  frequent 
  on 
  this 
  flower 
  

   in 
  his 
  garden. 
  The 
  species 
  is 
  fomid 
  on 
  the 
  commons 
  near 
  

   London, 
  and 
  is 
  abundant 
  locally 
  in 
  Norfolk 
  and 
  Suffolk, 
  

   and 
  very 
  common 
  in 
  mmierous 
  Devonshire 
  locahties, 
  both 
  

   on 
  the 
  coast 
  and 
  inland, 
  to 
  an 
  altitude 
  of 
  nearly 
  1000 
  ft, 
  

   above 
  the 
  sea. 
  It 
  is 
  also 
  found 
  in 
  Hampshire 
  and 
  Essex, 
  

   and 
  must 
  occur 
  in 
  several 
  other 
  comities 
  in 
  the 
  south. 
  I 
  

   have 
  never 
  seen 
  any 
  large 
  compact 
  colony 
  of 
  this 
  bee, 
  but 
  

   only 
  scattered 
  ones. 
  No 
  Nomada 
  appears 
  to 
  attack 
  it, 
  nor 
  

   is 
  it 
  infested 
  by 
  Sty 
  lops.* 
  

  

  A. 
  similis 
  Sm. 
  is 
  also 
  local, 
  but 
  occurs 
  on 
  a 
  number 
  of 
  

   commons 
  close 
  to 
  London 
  ; 
  was 
  found 
  commonly 
  at 
  Oxford 
  

   in 
  1886, 
  and 
  is 
  widely 
  distributed, 
  and 
  in 
  some 
  places 
  

   abundant, 
  in 
  Devonshire. 
  It 
  is 
  recorded 
  from 
  Denbigh- 
  

   shire 
  and 
  Essex, 
  and 
  is 
  found 
  in 
  Hampshire. 
  Some 
  

   examples 
  from 
  Colchester 
  sent 
  by 
  W. 
  H. 
  Harwood 
  for 
  my 
  

   inspection 
  many 
  years 
  ago 
  had 
  the 
  face 
  beneath 
  the 
  

   antennae 
  clothed 
  with 
  pale 
  fulvous 
  hairs, 
  instead 
  of 
  the 
  

   usual 
  white 
  ones, 
  this 
  being 
  the 
  usual 
  form 
  in 
  some 
  N. 
  

   European 
  localities. 
  Walcott 
  first 
  discovered 
  it, 
  at 
  Bristol, 
  

   and 
  supplied 
  Smith 
  with 
  specimens. 
  Sometimes 
  it 
  forms 
  

   compact 
  and 
  fairly 
  large 
  colonies, 
  and 
  the 
  males 
  will 
  be 
  

   seen 
  flying 
  over 
  the 
  soil 
  and 
  setthng, 
  for 
  the 
  purpose 
  of

  Recently 
  my 
  brother 
  has 
  sent 
  me 
  a 
  stylopised 
  female 
  from 
  

   East 
  Devon, 
  captured 
  on 
  March 
  26th, 
  1919.
