  the 
  original 
  description 
  given 
  by

  makes 
  no 
  

   mention 
  of 
  the 
  most 
  remarkable 
  characters 
  of 
  this 
  species. 
  

  

  Group 
  VIII. 
  

   This 
  is 
  the 
  central 
  group 
  of 
  the 
  genus, 
  and 
  contains 
  a 
  large 
  number 
  of 
  species, 
  

   which 
  seem 
  in 
  some 
  cases 
  to 
  be 
  so 
  closely 
  allied 
  as 
  to 
  be 
  undistinguishable, 
  thus 
  pre- 
  

   senting 
  the 
  phenomenon 
  of 
  races, 
  of 
  which 
  the 
  examples 
  are 
  already 
  so 
  numerous 
  in 
  

   this 
  as 
  in 
  every 
  other 
  department 
  of 
  Natural 
  History. 
  The 
  body 
  is 
  glabrous 
  above, 
  

   and 
  sometimes 
  pruinose 
  ; 
  the 
  head 
  is 
  small, 
  or 
  moderate 
  in 
  size 
  ; 
  the 
  clypeus 
  is 
  more 
  

   or 
  less 
  emarginate, 
  though 
  in 
  L. 
  serricornisit 
  is 
  entirely 
  rounded. 
  The 
  thorax 
  is 
  

   usually 
  gradually 
  broader 
  from 
  tip 
  to 
  base, 
  but 
  sometimes 
  its 
  widest 
  part 
  is 
  at 
  the 
  

   middle. 
  The 
  fifth 
  ventral 
  segment 
  is 
  broadly 
  emarginate, 
  and 
  in 
  the 
  male 
  is 
  

   variously 
  impressed, 
  while 
  the 
  last 
  of 
  the 
  same 
  sex 
  is 
  widely 
  but 
  not 
  deeply 
  exca- 
  

   vated. 
  The 
  ungues 
  are 
  variable 
  in 
  form, 
  even 
  between 
  closely 
  allied 
  species. 
  The 
  

   inner 
  spur 
  of 
  the 
  posterior 
  tibiaa 
  of 
  the 
  male 
  is 
  straight 
  and 
  connate, 
  while 
  in 
  the 
  

   female 
  both 
  are 
  free, 
  and 
  not 
  very 
  unequal. 
  

  

  According 
  to 
  the 
  form 
  of 
  the 
  clypeus 
  and 
  the 
  sides 
  of 
  the 
  thorax, 
  the 
  following 
  

   division 
  may 
  facilitate 
  the 
  determination 
  of 
  the 
  species 
  :
