   tinct 
  angle, 
  especially 
  on 
  the 
  metazona,

  8. 
  IMPUDICUS 
  SERIES. 
  

  

  This 
  group 
  is 
  composed 
  of 
  a 
  single 
  species 
  of 
  medium 
  size, 
  and 
  is 
  more 
  

   nearly 
  related 
  to 
  the 
  next 
  groui) 
  than 
  to 
  any 
  other. 
  The 
  prozona 
  is 
  

   slightly 
  longitudinal 
  in 
  the 
  male. 
  The 
  interspace 
  between 
  the 
  meso- 
  

   sternal 
  lobes 
  in 
  the 
  same 
  sex 
  is 
  nearly 
  half 
  as 
  long 
  again 
  as 
  broad 
  and 
  

   the 
  metasternal 
  lobes 
  are 
  only 
  approximate. 
  The 
  tegmina 
  are 
  fully 
  

   developed 
  and 
  surpass 
  the 
  hind 
  femora. 
  The 
  hind 
  tibiae 
  are 
  red 
  and 
  

   have 
  eleven 
  to 
  thirteen 
  spines 
  in 
  the 
  outer 
  series.
