  Head 
  and 
  thorax 
  black, 
  rugose-punc- 
  

   tate 
  ; 
  the 
  stemmata 
  placed 
  forwards 
  on 
  the 
  vertex 
  ; 
  antennae 
  

   ferruginous. 
  Thorax, 
  the 
  collar 
  produced 
  at 
  the 
  anterior 
  angles 
  

   into 
  a 
  short 
  acute 
  tooth 
  ; 
  the 
  metathorax 
  is 
  also 
  produced 
  at 
  the 
  

   posterior 
  angles 
  into 
  a 
  sharp 
  spine 
  ; 
  the 
  wings 
  ferruginous. 
  Legs 
  

   ferruginous, 
  the 
  coxae 
  and 
  trochanters 
  black. 
  Abdomen, 
  the 
  two 
  

   nodes

  This 
  insect 
  was 
  in 
  my 
  possession 
  some 
  time 
  before 
  Mr. 
  Bates 
  

   discovered 
  the 
  male 
  of 
  C, 
  clypeatus. 
  I 
  had 
  placed 
  it 
  with 
  " 
  C, 
  

   airatus" 
  as 
  being 
  probably 
  its 
  male, 
  but 
  I 
  had 
  no 
  other 
  evidence 
  

   of 
  its 
  being 
  a 
  male 
  Cryptoceriis 
  than 
  the 
  circumstance 
  of 
  its 
  agree- 
  

   ing 
  in 
  the 
  neuration 
  of 
  the 
  wings 
  with 
  that 
  genus 
  ; 
  from 
  its 
  size 
  I 
  

   still 
  suspect 
  it 
  to 
  be 
  the 
  male 
  of 
  " 
  airatus." 
  I 
  have 
  seen 
  no 
  second 
  

   example.

  lines. 
  Black, 
  opaque, 
  lateral 
  margins 
  of 
  the 
  

   head 
  dilated, 
  and 
  slightly 
  raised, 
  within 
  which 
  is 
  an 
  indistinct 
  

   longitudinal 
  ferruginous 
  stripe 
  ; 
  at 
  the 
  posterior 
  angles 
  of 
  the 
  

   head 
  are 
  two 
  acute 
  spines, 
  and 
  in 
  front 
  of 
  each 
  eye, 
  beneath 
  the 
  

   dilated 
  margin, 
  is 
  a 
  short 
  tooth 
  visible 
  from 
  above 
  ; 
  at 
  the 
  vertex 
  

   of 
  the 
  head 
  are 
  also 
  two 
  minute 
  spines. 
  At 
  the 
  anterior 
  angles 
  

   of 
  the 
  thorax 
  is 
  a 
  short 
  spine 
  or 
  tooth, 
  behind 
  which 
  is 
  a 
  stout 
  

   elongate 
  spine, 
  bidentate 
  at 
  the 
  apex 
  ; 
  the 
  posterior 
  angles 
  are 
  

   also 
  armed 
  with 
  acute 
  spines, 
  which 
  curve 
  outwardly

  the 
  posterior 
  node, 
  

   The 
  head, 
  thorax 
  and 
  nodes 
  of 
  the 
  abdomen 
  have 
  distant 
  large 
  

   shallow 
  punctures 
  ; 
  abdomen 
  very 
  delicately 
  shagreened, 
  polished 
  

   on
