  and 
  by 
  the 
  transverse 
  dorsal-plates 
  (" 
  Querstreifen 
  ") 
  which 
  are 
  still 
  

   contiguous 
  and 
  of 
  a 
  brown 
  colour. 
  At 
  this 
  time 
  of 
  year 
  I 
  found 
  in 
  each 
  

   nest 
  usually 
  one, 
  sometimes 
  two, 
  very 
  rarely 
  three, 
  individuals 
  of 
  this 
  

   modified 
  form. 
  Still 
  at 
  other 
  times 
  of 
  the 
  year, 
  before 
  they 
  obtain 
  

   wings, 
  their 
  number 
  must 
  be 
  very 
  large, 
  since 
  so 
  many 
  of 
  them 
  fly 
  out. 
  

   I 
  only 
  know 
  them 
  as 
  individuals 
  which 
  have 
  flown 
  from 
  their 
  nest 
  [i.e., 
  

   which 
  have 
  dropped 
  their 
  wings 
  — 
  T. 
  B. 
  F.], 
  and 
  at 
  that 
  time 
  their 
  four 
  

   wings 
  are 
  club-shaped, 
  on 
  the 
  outer 
  side 
  with 
  a 
  strong 
  margin, 
  rounded 
  

   at 
  the 
  tip, 
  veined, 
  finely 
  membranous, 
  brown, 
  of 
  almost 
  equal 
  lengths, 
  

   longer 
  and 
  many 
  times 
  broader 
  than 
  the 
  whole 
  body, 
  which 
  [wings] 
  

   however, 
  break 
  ofi 
  very 
  easily 
  near 
  their 
  base. 
  

  

  Fourthly, 
  the 
  soldiers 
  (" 
  Spadones 
  ")* 
  remain 
  to 
  be 
  noticed. 
  In 
  

   these 
  the 
  head 
  is 
  more 
  flattened, 
  narrower 
  and 
  more 
  hairy 
  than 
  in 
  the 
  

   male 
  [worker] 
  ; 
  hence 
  the 
  neck 
  is 
  not 
  so 
  rounded 
  of? 
  as 
  in 
  other 
  cases, 
  

   as 
  is 
  indicated 
  by 
  Sir 
  C. 
  von 
  Linne's 
  description 
  of 
  the 
  head. 
  They 
  have 
  

   only 
  the 
  upper 
  pair 
  of 
  mandibles 
  which 
  are 
  much 
  longer 
  and 
  project 
  much 
  

   more 
  beyond 
  the 
  mouth 
  and 
  are 
  often 
  crossed. 
  Each 
  of 
  them 
  is 
  straight, 
  

   slender, 
  pointed 
  inwardly 
  ; 
  towards 
  the 
  tip 
  it 
  has 
  a 
  strong 
  tooth, 
  is 
  nar- 
  

   row, 
  horny, 
  curved, 
  bent 
  inwards 
  and 
  also 
  upwards, 
  smooth, 
  black, 
  

   yellow 
  near 
  the 
  base. 
  In 
  the 
  lower 
  lip 
  the 
  parts 
  are 
  all 
  much 
  shorter 
  ; 
  

   but 
  their 
  [i.e., 
  of 
  the 
  divisions 
  of 
  the 
  lower 
  lip] 
  base 
  is 
  larger 
  and 
  stretches 
  

   further 
  back 
  towards 
  the 
  neck 
  and 
  is 
  as 
  if 
  composed 
  of 
  three 
  parts. 
  They 
  

   have, 
  however, 
  all 
  the 
  parts 
  of 
  the 
  head 
  as 
  described 
  for 
  the 
  male, 
  only 
  

   they 
  are 
  smaller 
  ; 
  the 
  abdomen 
  is 
  longer 
  and 
  more 
  slender. 
  

  

  Young 
  animals 
  were 
  abundant 
  at 
  this 
  time. 
  Those 
  most 
  developed 
  

   are 
  snow-white 
  ; 
  the 
  younger 
  ones 
  at 
  the 
  same 
  time 
  somewhat 
  trans- 
  

   parent. 
  On 
  the 
  abdomen 
  erect 
  hairs 
  are 
  plainly 
  visible. 
  Because 
  of 
  

   their 
  uniform 
  white 
  colour 
  I 
  could 
  make 
  no 
  discovery 
  about 
  the 
  eyes. 
  

   They 
  lived 
  in 
  the 
  innermost 
  combs 
  of 
  all 
  the 
  chambers. 
  

  

  The 
  eggs 
  are 
  usually 
  cylindrical, 
  rounded 
  at 
  both 
  ends, 
  small, 
  

   smooth, 
  shining, 
  milk-white, 
  somewhat 
  transparent 
  withal, 
  on 
  one 
  side 
  

   rather 
  more 
  opaque. 
  They 
  were 
  slightly 
  fastened 
  together 
  one 
  upon 
  

   another, 
  without 
  order, 
  on 
  the 
  walls 
  in 
  the 
  interior 
  of 
  the 
  combs 
  ; 
  

   some 
  of 
  the 
  large 
  combs 
  were 
  filled 
  full 
  of 
  them 
  ; 
  their 
  number 
  was 
  very 
  

   large 
  at 
  this 
  time 
  of 
  the 
  year. 
  By 
  which 
  of 
  these 
  animals 
  they 
  have 
  

   been 
  brought 
  there 
  [i.e., 
  into 
  the 
  combs] 
  and 
  how, 
  I 
  have 
  not 
  been 
  

   able 
  to 
  observe. 
  

  

  The 
  thorax 
  is 
  split 
  up 
  into 
  three 
  segments, 
  whereof 
  the 
  midmost 
  is 
  

   adjoining 
  the 
  neck, 
  whose 
  end 
  has 
  an 
  incision 
  ; 
  both 
  the 
  other 
  segments 
  

   are 
  divided 
  above 
  by 
  a 
  grove 
  and 
  small 
  points 
  project 
  at 
  the 
  sides.
