  wholly 
  testaceous. 
  They 
  are 
  crepuscular 
  or 
  nocturnal 
  insects, 
  and 
  

   can 
  be 
  captured

  The 
  specific 
  study 
  of 
  the 
  28 
  South 
  African 
  species 
  known 
  to 
  me 
  is 
  

   extremely 
  difficult. 
  An 
  examination 
  of 
  the 
  genital 
  armature 
  of 
  the 
  

   males, 
  as 
  figured 
  in 
  plate 
  xli. 
  will, 
  however, 
  easily 
  lead 
  to 
  their 
  

   identification, 
  but 
  all 
  the 
  females 
  are 
  extremely 
  alike. 
  I 
  have 
  had 
  

   no 
  difficulty, 
  however, 
  in 
  identifying 
  both 
  sexes 
  by 
  means 
  of 
  the 
  

   locality, 
  for 
  a 
  glance 
  at 
  the 
  habitat 
  of 
  the 
  species 
  shows 
  how 
  

   restricted 
  is 
  their 
  area 
  of 
  distribution 
  in 
  South 
  Africa, 
  and 
  so 
  far 
  

   as 
  I 
  know 
  A. 
  fuscipes 
  is 
  the 
  only 
  one 
  having 
  a 
  somewhat 
  wide 
  

   range, 
  for 
  it 
  occurs 
  in 
  the 
  Orange 
  Eiver 
  Colony, 
  in 
  Buluwayo, 
  and 
  

   Mazoe 
  in 
  Southern 
  Ehodesia, 
  and 
  also 
  in 
  Northern 
  Damaraland.
