  upper 
  side 
  and 
  having 
  in 
  the 
  

   base 
  of 
  the 
  prothorax 
  and 
  also 
  on 
  the 
  scutellum 
  and 
  elytra 
  a 
  few 
  

   widely 
  scattered, 
  whitish 
  scales, 
  traces 
  of 
  which 
  are 
  also 
  seen 
  on 
  the 
  

   sides 
  of 
  the 
  metasternum 
  and 
  on 
  the 
  abdominal 
  segments 
  ; 
  head 
  very 
  

   •scabrose 
  ; 
  clypeus 
  somewhat 
  excavate 
  and 
  with 
  the 
  margins 
  very 
  dis- 
  

   tinctly 
  raised, 
  strongly 
  angular 
  laterally 
  in 
  the 
  basal 
  part 
  and 
  slightly 
  

   oblique 
  there, 
  broad 
  at 
  the 
  tip, 
  slightly 
  emarginate 
  in 
  the 
  middle, 
  

   and 
  with 
  the 
  apical 
  angles 
  somewhat 
  rounded 
  ; 
  prothorax 
  deeply 
  and 
  

   very 
  closely 
  scabroso-punctate, 
  moderately 
  deeply 
  grooved 
  longitu- 
  

   dinally 
  in 
  the 
  middle 
  and 
  having 
  along 
  the 
  lateral 
  outer 
  margin 
  a 
  

   series 
  of 
  equi-distant, 
  sub-remote 
  short 
  black 
  bristles 
  ; 
  elytra 
  covered 
  

   with 
  somewhat 
  closely 
  set 
  transverse 
  scabrose 
  punctures 
  and 
  having 
  

   on 
  each 
  side 
  three 
  very 
  faint 
  costae 
  ; 
  pygidium 
  finely 
  punctulate 
  with 
  

   the 
  punctures 
  slightly 
  scabrose 
  ; 
  pectus 
  very 
  briefly 
  pubescent 
  ; 
  hind 
  

   femora 
  very 
  thick 
  and 
  with 
  the 
  trochanters 
  produced 
  into 
  a 
  long 
  

   spine, 
  hind 
  tibiae 
  somewhat 
  flattened 
  and 
  not 
  grooved 
  underneath 
  

   but 
  having 
  the 
  lower 
  edge 
  strongly 
  bi-dentate 
  near 
  the 
  knee 
  and 
  the 
  

   apical 
  part 
  mucronate 
  on 
  each 
  side, 
  in 
  the 
  great 
  development 
  the 
  

   second 
  inner 
  tooth 
  is 
  sometimes 
  truncate 
  at 
  tip 
  or 
  slightly 
  bifid 
  ; 
  hind 
  

   claws 
  single, 
  simple. 
  

  

  Female 
  : 
  Fulvous 
  brown, 
  and 
  with 
  the 
  upper 
  side, 
  the 
  abdomen 
  

   and 
  legs 
  covered 
  with 
  moderately 
  closely 
  set, 
  elongate 
  whitish 
  scales 
  

   turning 
  to 
  squamiform 
  appressed 
  hairs 
  on 
  the 
  pygidium 
  ; 
  the 
  head 
  

   is 
  shaped 
  as 
  in 
  the 
  male, 
  but 
  the 
  apical 
  margin 
  is 
  still 
  more 
  highly 
  

   reflexed 
  ; 
  the 
  two 
  apical 
  outer 
  teeth 
  of 
  the 
  fore 
  tibiae 
  are 
  more 
  robust 
  

   than 
  in 
  the 
  male, 
  and 
  the 
  hind 
  claws 
  are 
  single 
  and 
  simple.

  mm. 
  ; 
  width

  mm. 
  

  

  I 
  have 
  often 
  met 
  with 
  this 
  species 
  in 
  fields 
  of 
  corn 
  or 
  oats, 
  at 
  the 
  

   beginning 
  of 
  the 
  spring 
  (September) 
  but 
  I 
  have 
  very 
  seldom 
  captured 
  

   iihe 
  female, 
  whose 
  facies 
  differs 
  very 
  strongly 
  from 
  that 
  of 
  the 
  male.
