  RUSTICUS 
  SERIES. 
  

  

  This 
  is 
  a 
  tolerably 
  homogeneous 
  group 
  in 
  which 
  the 
  prozona 
  of 
  the 
  

   male 
  varies 
  from 
  quadrate 
  to 
  distinctly 
  longitudinal 
  and 
  in 
  which 
  the 
  

   mesosternal 
  lobes 
  of 
  the 
  same 
  sex 
  are 
  sei)arated 
  by 
  an 
  inters])a(;e 
  

   which 
  is 
  rarely 
  a 
  little 
  transverse, 
  usually 
  quadrate 
  or 
  subquadrate, 
  

   and 
  rarely 
  as 
  much 
  as 
  nearly 
  half 
  as 
  long 
  again 
  as 
  broad. 
  The 
  hind 
  

   border 
  of 
  the 
  pronotum 
  is 
  usually 
  very 
  obtusangulate, 
  and 
  the 
  tegmina 
  

   always 
  abbreviate, 
  usually 
  about 
  as 
  long 
  as 
  the 
  pronotum. 
  The 
  

   hind 
  tibiae 
  are 
  usually 
  red, 
  rarely 
  pale 
  greenish, 
  with 
  usually 
  ten 
  to 
  

   eleven 
  spines 
  in 
  the 
  outer 
  series, 
  but 
  sometimes 
  nine 
  or 
  twelve, 
  and 
  in 
  

   one 
  case 
  only 
  seven 
  spines 
  may 
  be 
  found 
  in 
  the 
  female. 
  

  

  The 
  male 
  abdomen 
  is 
  usually 
  more 
  or 
  less 
  clavate 
  and 
  recurved, 
  the 
  

   supraanal 
  plate 
  triangular, 
  its 
  median 
  sulcus 
  inclosed 
  by 
  high 
  walls
