  Group 
  VI. 
  

   In 
  this 
  group 
  we 
  have 
  a 
  species 
  of 
  oblong 
  form, 
  glabrous 
  upper 
  surface, 
  and 
  10-jointed 
  

   antenna?; 
  the 
  clypeus 
  is 
  slightly 
  emarginate, 
  the 
  mandibles 
  are 
  but 
  little 
  prominent, 
  

   the 
  last 
  joint 
  of 
  the 
  maxillary 
  palpi 
  is 
  distinctly 
  oval, 
  but 
  has 
  no 
  lateral 
  impression. 
  

   The 
  thorax 
  is 
  not 
  narrowed 
  at 
  the 
  base, 
  and 
  is 
  hardly 
  serrate 
  on 
  the 
  sides 
  : 
  the 
  upper 
  

   spur 
  of 
  the 
  posterior 
  tibia? 
  of 
  the 
  male 
  is 
  fixed, 
  laterally 
  inserted 
  and 
  is 
  oblique, 
  thus 
  

   causing 
  the 
  apical 
  portion 
  of 
  the 
  tibiae 
  to 
  be 
  emarginate 
  beneath 
  : 
  the 
  upper 
  spur 
  is 
  

   flattened 
  and 
  acute 
  : 
  the 
  claws 
  are 
  armed 
  with 
  a 
  short 
  acute 
  tooth 
  at 
  the 
  middle.

  The 
  pygidiuui 
  is 
  sparsely 
  but 
  strongly 
  punctured. 
  

   Only 
  males 
  are 
  known 
  to 
  me, 
  and 
  in 
  them 
  the 
  club 
  of 
  the 
  antenna? 
  is 
  longer 
  than 
  the 
  

   stem, 
  the 
  last 
  three 
  segments 
  of 
  the 
  abdomen 
  are 
  broadly 
  and 
  deeply 
  channeled, 
  the 
  

   penultimate 
  has 
  a 
  deep 
  posterior 
  longitudinal 
  line, 
  and 
  the 
  last 
  a 
  triangular 
  space 
  

   limited 
  each 
  side 
  by 
  a 
  sharply 
  defined 
  edge 
  ; 
  the 
  outline 
  of 
  the 
  apex 
  is 
  sinuous, 
  and 
  

   has 
  two 
  small 
  lobes 
  at 
  the 
  middle. 
  The 
  inner 
  posterior 
  spur 
  is 
  straight, 
  not 
  shorter 
  

   than 
  the 
  outer, 
  but 
  oblicme 
  and 
  connate, 
  inserted 
  upon 
  the 
  side, 
  so 
  as 
  to 
  produce 
  a 
  

   deep 
  inferior 
  emargination. 
  

  

  Group 
  VII. 
  

   Contains 
  a 
  single 
  oblong 
  convex 
  species, 
  which, 
  although 
  glabrous 
  above, 
  is 
  fringed 
  

   on 
  the 
  margin 
  with 
  long 
  erect 
  hairs. 
  The 
  head 
  is 
  moderate, 
  the 
  clypeus 
  narrowly 
  

   margined, 
  slightly 
  emarginate 
  ; 
  the 
  antenna? 
  are 
  10-jointed, 
  the 
  last 
  joint 
  of 
  the 
  

   maxillary 
  palpi 
  slender, 
  not 
  impressed. 
  The 
  thorax 
  is 
  not 
  narrowed 
  behind 
  ; 
  the 
  

   breast 
  is 
  clothed 
  with 
  long 
  dense 
  hair 
  ; 
  the 
  inner 
  spur 
  of 
  the 
  posterior 
  tibia? 
  of 
  the 
  

   male 
  is 
  very 
  long 
  and 
  irregularly 
  bent, 
  the 
  outer 
  one 
  is 
  ecuially 
  long, 
  but 
  straight 
  

   and 
  slender 
  ; 
  the 
  tarsi 
  are 
  long, 
  and 
  the 
  claws 
  armed 
  with 
  a 
  long 
  tooth 
  a 
  little 
  beyond 
  

   the 
  middle, 
  so 
  as 
  almost 
  to 
  appear 
  cleft.
