  Mr. 
  Cameron 
  oji 
  

  

  lower 
  part 
  of 
  cheeks 
  densely 
  covered 
  with 
  silvery 
  hair. 
  

   Front 
  raised, 
  furrowed 
  down 
  the 
  centre, 
  bearing 
  large, 
  

   distinct 
  punctures, 
  narrowed 
  before 
  the 
  antennae 
  into 
  a 
  

   wedge. 
  The 
  eyes 
  at 
  top 
  are 
  separated 
  by 
  the 
  length 
  of 
  the 
  

   second 
  and 
  third 
  antennal 
  joints 
  united 
  ; 
  ocelli 
  rather 
  

   widely 
  separated 
  ; 
  clypeus 
  with 
  a 
  raised 
  margin, 
  sharply 
  

   rounded 
  at 
  the 
  apex. 
  Mandibles 
  reddish 
  beyond 
  the 
  base. 
  

   Thorax 
  shining, 
  covered 
  with 
  long 
  fuscous 
  hair 
  ; 
  mesonotum 
  

   rather 
  strongly 
  punctured 
  ; 
  the 
  scutellum 
  and 
  fore 
  part 
  of 
  

   the 
  mesopleurae 
  slightly 
  punctured 
  ; 
  the 
  hinder 
  part 
  of 
  the 
  

   latter 
  impunctate. 
  Metanotum 
  strongly 
  transversely 
  

   striolated, 
  the 
  striae 
  wide 
  apart 
  ; 
  there 
  is 
  a 
  wedge-shaped 
  

   depression 
  in 
  the 
  centre 
  of 
  the 
  upper 
  part 
  ; 
  the 
  depression 
  

   with 
  a 
  keel 
  down 
  its 
  edges 
  ; 
  there 
  are 
  two 
  lateral 
  keels 
  

   and 
  the 
  posterior 
  part 
  of 
  the 
  metanotum 
  is 
  widely 
  excavated 
  

   in 
  the 
  centre 
  ; 
  this 
  portion 
  having 
  a 
  gradual 
  rounded 
  curved 
  

   slope. 
  Petiole 
  as 
  long 
  as 
  the 
  mesothorax, 
  clavate 
  ; 
  fully 
  

   one-third 
  longer 
  than 
  the 
  second 
  segment 
  ; 
  the 
  latter 
  is 
  a 
  

   little 
  longer 
  than 
  the 
  third, 
  and 
  both 
  have 
  an 
  elongate 
  fovea 
  

   on 
  the 
  top 
  at 
  the 
  apex. 
  At 
  the 
  apex 
  the 
  abdomen 
  is 
  

   sparsely 
  pilose. 
  Femora 
  sparsely 
  haired 
  ; 
  tibiae 
  and 
  tarsi 
  

   closely 
  pilose 
  ; 
  spurs 
  pale 
  testaceous. 
  

  

  Trypoxylon 
  accumulator. 
  

  

  In 
  this 
  species 
  the 
  front 
  is 
  not 
  much 
  raised 
  on 
  either 
  

   side 
  of 
  the 
  central 
  furrow, 
  which 
  is 
  wide 
  but 
  shallow 
  ; 
  the 
  

   eyes 
  at 
  the 
  top 
  are 
  separated 
  by 
  about 
  the 
  length 
  of 
  the 
  

   third 
  antennal 
  joint, 
  at 
  the 
  bottom 
  below 
  the 
  antennae 
  by 
  

   fully 
  more 
  than 
  the 
  length 
  of 
  the 
  third. 
  The 
  third 
  joint 
  of 
  

   the 
  antennae 
  is 
  nearly 
  one-half 
  longer 
  than 
  the 
  fourth. 
  

   Clypeus 
  broadly 
  carinate, 
  the 
  apex 
  projecting, 
  broadly 
  

   rounded. 
  Petiole 
  longer 
  than 
  the 
  thorax, 
  rather 
  abruptly 
  

   dilated 
  towards 
  the 
  apex 
  ; 
  the 
  second 
  segment 
  distinctly 
  

   shorter 
  than 
  the 
  third.
