﻿PROCEEDINGS 
  OF 
  THE 
  FOURTH 
  ENTOMOLOGICAL 
  MEETING 
  319 
  

  

  soil 
  is 
  three 
  feet. 
  In 
  flat 
  and 
  elevated 
  ground, 
  the 
  chimneys, 
  which 
  they 
  

   are 
  wont 
  to 
  erect, 
  are 
  at 
  the 
  most 
  two 
  feet 
  high 
  ; 
  but 
  it 
  is 
  different 
  if 
  

   the 
  ants 
  build 
  amongst 
  bushes, 
  on 
  old 
  stumps, 
  or 
  on 
  the 
  bunds 
  

   (" 
  Reinen 
  ") 
  of 
  the 
  wet 
  rice-fields 
  ; 
  as 
  then 
  their 
  mounds 
  rear 
  up 
  like 
  

   old 
  ruins 
  to 
  a 
  man's 
  height 
  above 
  ground-level. 
  The 
  number 
  of 
  these 
  

   chimneys, 
  which 
  have 
  more 
  than 
  one 
  opening, 
  is 
  not 
  so 
  accurately 
  

   defined 
  ; 
  however, 
  there 
  is 
  rarely 
  more 
  than 
  one 
  principal 
  chimney 
  which 
  

   is 
  built 
  up 
  like 
  a 
  pillar 
  ; 
  the 
  others 
  are 
  only 
  low 
  ones. 
  

  

  The 
  principal 
  entrances 
  which 
  lead 
  through 
  these 
  chimneys 
  into 
  the 
  

   earth 
  to 
  the 
  separately 
  constructed 
  chambers 
  of 
  the 
  nest 
  (" 
  abgetheilten 
  

   Wohnungen 
  ") 
  occur 
  in 
  various 
  numbers 
  and 
  are 
  quite 
  irregular. 
  At 
  

   first 
  they 
  go 
  vertically 
  downwards, 
  but 
  divide 
  as 
  soon 
  as 
  they 
  reach 
  

   below 
  ground-level 
  into 
  numerous 
  small 
  passages, 
  and 
  they 
  are 
  mostly 
  

   round. 
  In 
  addition 
  to 
  these, 
  the 
  nests 
  have 
  now 
  and 
  then 
  cavities 
  

   which 
  are 
  at 
  a 
  lower 
  level, 
  and 
  sometimes 
  even 
  quite 
  small 
  ones 
  at 
  some 
  

   depth 
  in 
  the 
  ground. 
  

  

  Each 
  single 
  nest 
  is 
  divided 
  up 
  into 
  many 
  chambers 
  separated 
  from 
  

   one 
  another 
  ; 
  but 
  these 
  arc 
  placed 
  so 
  irregularly 
  that 
  nothing 
  definite 
  

   can 
  be 
  said 
  regarding 
  their 
  divisions. 
  They 
  are 
  found 
  approximately 
  

   in 
  three 
  rows 
  one 
  below 
  the 
  other 
  and 
  the 
  uppermost 
  lies 
  barely 
  a 
  foot 
  

   below 
  the 
  ground. 
  

  

  Each 
  single 
  chamber 
  forms 
  a 
  conical 
  vault 
  which 
  is 
  quite 
  flat 
  at 
  the 
  

   bottom 
  and 
  is 
  rounded 
  well-nigh 
  spherically 
  at 
  the 
  top. 
  Their 
  inner- 
  

   surface 
  is 
  everywhere 
  quite 
  smooth 
  and 
  even 
  and 
  they 
  are 
  separated 
  

   from 
  each 
  other 
  by 
  strong 
  partition 
  walls 
  consisting 
  of 
  soil 
  (" 
  durch 
  

   starke 
  Zwischenraume 
  von 
  Erde 
  getrennt."). 
  The 
  entrance 
  to 
  each 
  

   chamber 
  is 
  found 
  at 
  one 
  side, 
  near 
  the 
  floor, 
  and 
  I 
  have 
  never 
  found 
  

   more 
  than 
  one; 
  these 
  lead, 
  as 
  stated 
  above, 
  from 
  the 
  divided 
  main- 
  

   galleries. 
  

  

  Very 
  rarely 
  I 
  have 
  found 
  that 
  the 
  upper 
  chamber 
  had 
  a 
  gallery 
  

   through 
  its 
  floor 
  leading 
  to 
  the 
  lower 
  chamber. 
  

  

  The 
  height 
  of 
  a 
  single 
  one 
  of 
  the 
  finished 
  chambers 
  is 
  not 
  above 
  two- 
  

   thirds 
  of 
  a 
  foot, 
  and 
  in 
  diameter 
  it 
  is 
  somewhat 
  more 
  than 
  half 
  the 
  height. 
  

  

  The 
  semiglobular 
  shape 
  of 
  its 
  arch 
  appears 
  to 
  be 
  characteristic 
  of 
  

   it 
  ; 
  for 
  this 
  is 
  invariably 
  found 
  in 
  all 
  newly 
  commenced 
  and 
  small 
  cham- 
  

   bers. 
  

  

  Their 
  dwellings 
  [i.e., 
  the 
  fungus-combs] 
  have, 
  as 
  stated, 
  the 
  shape 
  

   of 
  the 
  vault 
  [in 
  which 
  they 
  are 
  placed] 
  except 
  that 
  they 
  are 
  separated 
  

   everywhere 
  from 
  the 
  inside 
  wall 
  by 
  a 
  small 
  interval 
  ; 
  also 
  on 
  the 
  bottom 
  

   there 
  is 
  not 
  to 
  be 
  found 
  the 
  slightest 
  trace 
  that 
  they 
  are 
  made 
  firm 
  

   somehow 
  or 
  other 
  by 
  an 
  adhesive 
  substance 
  or 
  by 
  any 
  other 
  means.
