  Mr.

  Waterhouse's 
  Descriptions 
  of 
  

  

  produced 
  in 
  front, 
  and 
  keeled 
  above 
  ; 
  the 
  elytra 
  are 
  short, 
  the 
  

   sides 
  nearly 
  straight, 
  but 
  diverging 
  gradually 
  from 
  the 
  base 
  to 
  the 
  

   posterior 
  third, 
  from 
  which 
  point 
  they 
  rather 
  suddenly 
  converge 
  

   towards 
  the 
  apex, 
  which 
  might 
  be 
  described 
  as 
  obtusely 
  rounded, 
  

   were 
  it 
  not 
  that 
  the 
  sutural 
  portion 
  projects 
  and 
  forms 
  an 
  angle 
  

   in 
  the 
  middle 
  \ 
  the 
  apical 
  portion 
  is 
  much 
  bent 
  downwards, 
  so 
  as 
  

   to 
  form 
  an 
  obtuse 
  angle 
  with 
  the 
  dorsal 
  surface, 
  the 
  sides 
  are 
  nearly 
  

   vertical, 
  the 
  back 
  moderately 
  convex 
  ; 
  the 
  legs 
  rather 
  short 
  and 
  

   very 
  thick. 
  

  

  Plagiocorynus 
  quadrituberculatus. 
  

  

  Oblongus, 
  niger, 
  umbrino-squamosus 
  ; 
  fronte 
  foveolata 
  ; 
  rostro 
  

   valido 
  perparum 
  arcuato, 
  supra 
  ruguso-punctato, 
  irregu- 
  

   lariter 
  quadri-carinato, 
  squamulis 
  setiformibus 
  semi-erectis, 
  

   obsito 
  ; 
  thorace 
  utrinque 
  parum 
  rotundato-ampliato, 
  supra 
  

   convexo, 
  rugoso-punctato, 
  medio 
  carinato, 
  utrinque 
  disci 
  

   carinula 
  brevi 
  notato 
  ; 
  elytris 
  tuberculis 
  parvulis 
  rotundis 
  

   scrobiculisque 
  alternatim 
  et 
  seriatim 
  notatis 
  ; 
  pone 
  medium 
  

   tuberculis 
  quatuor 
  transversim 
  obsitis.

  ;

  Head 
  coarsely 
  punctured, 
  with 
  a 
  deep 
  fovea 
  surrounded 
  by 
  a 
  

   slight 
  ridge 
  on 
  the 
  forehead 
  ; 
  rostrum 
  with 
  four 
  longitudinal 
  

   ridges 
  on 
  the 
  basal 
  portion 
  ; 
  scape 
  of 
  antennae 
  apparently 
  with 
  a 
  

   small 
  tuft 
  of 
  scales 
  in 
  the 
  middle 
  of 
  the 
  under 
  side. 
  Thorax 
  

   equal 
  in 
  length 
  and 
  breadth, 
  the 
  sides 
  slightly 
  rounded 
  ; 
  the 
  

   margin 
  of 
  the 
  anterior 
  lobe 
  slightly 
  raised 
  ; 
  the 
  dorsal 
  keel 
  high, 
  

   and 
  continued 
  from 
  the 
  base 
  to 
  the 
  apex 
  of 
  the 
  thorax. 
  Elytra 
  

   rather 
  strongly 
  trisinuated 
  in 
  front, 
  and 
  closely 
  applied 
  to 
  the 
  

   thorax, 
  with 
  small 
  pits 
  arranged 
  in 
  longitudinal 
  series 
  in 
  place 
  of 
  

   the 
  ordinary 
  punctures 
  of 
  the 
  striae 
  ; 
  these 
  pits 
  filled 
  with 
  scales, 
  

   and 
  separated 
  from 
  each 
  other 
  by 
  a 
  small 
  rounded 
  tubercle, 
  which 
  

   is 
  but 
  little 
  raised 
  — 
  they 
  are 
  most 
  distinct 
  on 
  the 
  sides 
  of 
  the 
  

   elytra, 
  and 
  are 
  wanting 
  on 
  the 
  apical 
  portion. 
  The 
  interstices 
  are 
  

   for 
  the 
  most 
  part 
  flat 
  ; 
  but 
  the 
  second 
  interstice 
  from 
  the 
  suture 
  

   is 
  slightly 
  raised. 
  Rather 
  behind 
  the 
  middle 
  of 
  the 
  elytra 
  (at 
  the 
  

   part 
  where 
  they 
  are 
  suddenly 
  bent 
  down) 
  is 
  a 
  transverse 
  row 
  of 
  

   four 
  tubercles 
  ; 
  the 
  innermost 
  tubercle 
  on 
  either 
  side 
  is 
  large 
  and 
  

   obtuse, 
  and 
  clothed 
  with 
  erect 
  dusky 
  setiform 
  scales; 
  the 
  outer 
  

   tubercle 
  is 
  small 
  and 
  obtuse, 
  and 
  clothed 
  with 
  the 
  same 
  rich 
  

   brown 
  scales 
  as 
  other 
  parts. 
  The 
  legs 
  are 
  densely 
  clothed 
  with 
  

   scales, 
  which 
  in 
  parts, 
  especially 
  on 
  the 
  tibiae, 
  assume 
  nearly 
  the 
  

   form 
  of 
  short 
  bristles.
