  I 
  have 
  in 
  my 
  collection 
  one 
  adult 
  male 
  and 
  two 
  immature 
  females 
  

   from 
  Apus 
  andecolus 
  parvulus 
  (Berlepsch 
  and 
  Stolzmann) 
  collected 
  

   at 
  Huarmey, 
  Peru, 
  and 
  one 
  adult 
  female 
  from 
  the 
  type 
  host 
  collected 
  

   at 
  Oploca, 
  Bolivia. 
  The 
  type 
  of 
  australis 
  is 
  a 
  female, 
  and 
  my 
  female 
  

   from 
  Oploca 
  agrees 
  closely 
  with 
  Ewing's 
  description 
  and 
  figure 
  of 
  the 
  

   species, 
  although 
  the 
  measurements 
  differ 
  slightly, 
  those 
  given 
  for 
  

   the 
  type 
  being 
  2.75 
  by 
  1.30, 
  while 
  my 
  female 
  measures 
  2.86 
  by 
  1.19. 
  

  

  The 
  male 
  from 
  A. 
  andecolus 
  parvulus 
  has 
  exactly 
  the 
  same 
  shape, 
  

   structure, 
  and 
  chaetotaxy 
  of 
  the 
  head 
  as 
  the 
  female, 
  as 
  well 
  as 
  the
