  the 
  tliorax, 
  with 
  the 
  humerus 
  projecting 
  and 
  angular, 
  the 
  dorsal 
  

   surface 
  considerably 
  arched 
  ; 
  with 
  coarse 
  punctures 
  and 
  scattered 
  

   granules, 
  an 
  equal 
  row 
  of 
  fine 
  nearly 
  equidistant 
  tubercles, 
  one 
  of 
  

   which 
  is 
  small, 
  and 
  close 
  to 
  the 
  apex 
  ; 
  the 
  others 
  are 
  large 
  and 
  

   conical, 
  and 
  the 
  sub-apical 
  tubercle 
  is 
  very 
  large 
  and 
  sub-acute 
  ; 
  

   besides 
  these 
  there 
  is 
  a 
  row 
  of 
  three 
  smaller 
  tubercles 
  arranged 
  

   in 
  an 
  oblique 
  line, 
  running 
  from 
  the 
  shoulder 
  to 
  the 
  third 
  of 
  the 
  

   dorsal 
  tubercles. 
  On 
  the 
  sides 
  of 
  the 
  elytra 
  are 
  three 
  rows 
  of 
  

   comparatively 
  small 
  punctures, 
  and 
  these 
  very 
  widely 
  separated, 
  

   and 
  each 
  one 
  incloses 
  a 
  scale 
  ; 
  between 
  these 
  rows 
  of 
  punctures 
  

   there 
  are 
  series 
  of 
  large 
  and 
  but 
  little 
  raised 
  granules. 
  The 
  scales 
  

   are 
  tolerably 
  dense, 
  pale 
  ash 
  colour 
  on 
  the 
  thorax, 
  excepting 
  on 
  

   the 
  disc 
  and 
  on 
  the 
  tubercles, 
  where 
  they 
  are 
  brown 
  ; 
  the 
  gra- 
  

   nules 
  here 
  and 
  elsewhere 
  are 
  denuded 
  ; 
  they 
  are 
  scattered 
  over 
  

   the 
  surface 
  of 
  the 
  four 
  dorsal 
  tubercles 
  as 
  well 
  as 
  other 
  parts 
  of 
  

   the 
  thorax. 
  On 
  the 
  sides 
  of 
  the 
  elytra 
  the 
  scales 
  are 
  rufous 
  

   brown 
  ; 
  on 
  the 
  upper 
  parts 
  they 
  are 
  chiefly 
  ash-coloured, 
  except- 
  

   ing 
  on 
  the 
  space 
  between 
  the 
  inner 
  rows 
  of 
  tubercles, 
  where 
  the 
  

   brown 
  tint 
  prevails. 
  The 
  legs 
  are 
  rather 
  larger 
  and 
  more 
  slender 
  

   than 
  in 
  the 
  other 
  species 
  described 
  in 
  this 
  paper. 
  On 
  the 
  abdo- 
  

   men 
  are 
  three 
  longitudinal 
  denuded 
  bands.

   The 
  form 
  of 
  the 
  club 
  of 
  the 
  antennae 
  in 
  this 
  genus 
  differs 
  from 
  

   that 
  of 
  other 
  Cryptorhynchides, 
  it 
  being 
  short, 
  and 
  obliquely 
  trun- 
  

   cated 
  on 
  the 
  outer 
  side, 
  and 
  the 
  terminal 
  joints 
  are 
  as 
  it 
  were 
  

   thrust 
  into 
  the 
  basal 
  joint 
  ; 
  the 
  rostrum 
  is 
  thick, 
  sub-angular, 
  has 
  

   four 
  irregular 
  keels 
  above, 
  and 
  is 
  unusually 
  short, 
  being 
  but 
  little 
  

   longer 
  than 
  the 
  head 
  ; 
  the 
  thorax 
  is 
  large, 
  much 
  contracted 
  and
