   A 
  translation 
  of 
  Professor 
  Leonardi' 
  s 
  description 
  is 
  as 
  follows 
  : 
  — 
  

  

  ' 
  Female. 
  Body 
  elongate, 
  with 
  the 
  extremity 
  rounded 
  and 
  having 
  the 
  greatest 
  

   width 
  about 
  the 
  middle. 
  The 
  abdominal 
  segments 
  narrower 
  than 
  the 
  cephalothorax 
  

   and 
  projecting 
  laterally 
  in 
  well 
  defined 
  lobes, 
  which 
  have 
  their 
  free 
  margins 
  rounded. 
  

   The 
  lobes 
  of 
  the 
  last 
  abdominal 
  segments 
  have 
  2-3 
  long 
  and 
  robust 
  hairs 
  along 
  the 
  

   free 
  margin. 
  The 
  buccal 
  apparatus 
  with 
  the 
  maxillary-mandibular 
  bristles 
  radiating 
  

   and 
  extending 
  beyond 
  the 
  posterior 
  extremity 
  of 
  the 
  body. 
  

  

  Antennae 
  tuberculiform 
  and 
  surmounted 
  with 
  a 
  long 
  nagellum. 
  Posterior 
  

   stigmata 
  without 
  glands. 
  

  

  Pygidium 
  with 
  two 
  pairs 
  of 
  lobes, 
  of 
  which 
  the 
  middle 
  pair, 
  which 
  is 
  deeply 
  

   coloured, 
  has 
  the 
  inner 
  margins 
  approximated 
  and 
  the 
  outer 
  more 
  deeply 
  incised. 
  

   Those 
  of 
  the 
  second 
  pair 
  are 
  separated 
  from 
  the 
  first 
  by 
  a 
  robust 
  hair, 
  and 
  by 
  the 
  

   mouth 
  of 
  a 
  large 
  wax-gland. 
  They 
  are 
  very 
  small, 
  slender, 
  somewhat 
  hyaline, 
  with 
  

   the 
  free 
  margin 
  rounded 
  and 
  entire. 
  On 
  the 
  outer 
  side 
  of 
  each 
  of 
  the 
  second 
  lobes 
  

   there 
  is 
  first 
  a 
  hair, 
  then 
  the 
  mouths 
  of 
  two 
  large 
  wax-glands, 
  and 
  at 
  a 
  certain 
  distance 
  

   from 
  these 
  another 
  hair 
  followed 
  by 
  the 
  mouths 
  of 
  two 
  other 
  wax-glands, 
  and 
  lastly 
  

   near 
  the 
  pre-anal 
  segment 
  a 
  fourth 
  hair.
