  rable 
  to 
  this 
  species. 
  The 
  antennae 
  bear 
  a 
  short 
  white 
  pile, 
  

   and 
  have 
  the 
  third 
  joint 
  less 
  than 
  one-fourth 
  longer 
  than 
  the 
  

   fourth. 
  The 
  cheeks, 
  eye 
  incision, 
  and 
  clypeus 
  are 
  densely 
  

   covered 
  with 
  silvery 
  pubescence 
  ; 
  the 
  front 
  and 
  vertex 
  are 
  

   shining, 
  minutely 
  punctured 
  ; 
  and 
  there 
  is 
  in 
  the 
  latter 
  a 
  

   large 
  depression, 
  rounded 
  behind, 
  triangular 
  in 
  front, 
  with 
  a 
  

   distinct 
  raised 
  margin 
  ; 
  from 
  the 
  middle 
  (at 
  the 
  angle) 
  a 
  

   short 
  keel 
  runs 
  to 
  the 
  eye 
  incision 
  ; 
  and 
  from 
  the 
  apex 
  a 
  

   stout 
  keel 
  runs 
  to 
  the 
  antennae. 
  At 
  the 
  top 
  the 
  eyes 
  are 
  

   separated 
  by 
  the 
  length 
  nearly 
  of 
  the 
  second 
  and 
  third 
  

   joints 
  united. 
  The 
  two 
  hinder 
  ocelli 
  are 
  placed 
  in 
  round 
  

   depressions, 
  and 
  are 
  separated 
  by 
  a 
  margin 
  ; 
  the 
  front 
  

   ocellus 
  is 
  placed 
  in 
  the 
  large 
  frontal 
  area. 
  The 
  meta- 
  

   notum 
  is 
  strongly 
  transversely 
  striolated 
  ; 
  at 
  the 
  base 
  in 
  

   the 
  centre 
  there 
  is 
  a 
  wide 
  furrow, 
  twice 
  longer 
  than 
  broad, 
  

   surrounded 
  by 
  a 
  broad 
  margin 
  ; 
  and 
  on 
  either 
  side 
  of 
  this 
  

   is 
  a 
  broad 
  furrow 
  which 
  unites 
  into 
  a 
  broad 
  furrow 
  running 
  

   down 
  the 
  centre 
  to 
  the 
  apex. 
  The 
  metapleurse 
  are 
  much 
  

   more 
  finely 
  and 
  closely 
  striolated. 
  The 
  mesonotum 
  is 
  

   finely 
  punctured, 
  and 
  is 
  of 
  almost 
  an 
  olive 
  hue. 
  The 
  

   abdomen 
  is 
  more 
  than 
  twice 
  the 
  length 
  of 
  the 
  head 
  and 
  

   thorax 
  united. 
  The 
  petiole 
  is 
  nearly 
  twice 
  the 
  length 
  of 
  

   the 
  second 
  joint. 
  The 
  calcaria 
  are 
  pale. 
  

  

  The 
  peculiar 
  shield-shaped 
  depression 
  separates 
  this 
  

   species 
  readily 
  from 
  the 
  others. 
  

  

  Trypoxylon 
  intrudens. 
  

  

  Smith 
  has 
  named 
  doubtfully 
  some 
  specimens 
  in 
  Mr. 
  

   Rothney's 
  collection 
  as 
  this 
  species. 
  They 
  have 
  the 
  head 
  

   rather 
  strongly 
  punctured 
  ; 
  the 
  front 
  furrowed 
  in 
  the 
  centre 
  ; 
  

   the 
  eyes 
  at 
  the 
  top 
  separated 
  by 
  the 
  length 
  of 
  the 
  third 
  

   antennal 
  joint 
  ; 
  there 
  is 
  a 
  wide 
  furrow 
  in 
  the 
  centre 
  of 
  the 
  

   metanotum, 
  with 
  a 
  curved 
  narrower 
  furrow 
  on 
  either 
  side 
  of 
  

   it, 
  meeting 
  at 
  the 
  central 
  apical 
  furrow. 
  The 
  furrows 
  trans- 
  

   versely 
  striolated 
  ; 
  the 
  rest 
  of 
  the 
  metanotum 
  finely 
  punc-
