  Mr. 
  G. 
  R. 
  Waterhouse's 
  Descriptions 
  of 
  

  

  have 
  been 
  originally 
  covered 
  throughout 
  the 
  upper 
  parts 
  with 
  

   dirty 
  brown 
  scales, 
  but 
  these 
  have 
  been 
  in 
  a 
  great 
  measure 
  rubbed 
  

   off. 
  Each 
  of 
  the 
  rows 
  of 
  tubercles 
  on 
  the 
  elytra 
  consists 
  of 
  four 
  

   large, 
  nearly 
  equal, 
  rounded 
  tubercles, 
  the 
  foremost 
  being 
  very 
  

   near 
  the 
  base 
  of 
  the 
  elytra, 
  and 
  the 
  hindermost 
  far 
  removed 
  from 
  

   the 
  apex 
  ; 
  besides 
  which 
  there 
  are 
  two 
  or 
  three 
  small 
  tubercles 
  

   near 
  the 
  apex, 
  and 
  there 
  is 
  a 
  small 
  tubercle 
  on 
  the 
  anterior 
  margin 
  

   on 
  either 
  side 
  at 
  some 
  distance 
  from 
  the 
  scutellum. 
  The 
  trans- 
  

   verse 
  and 
  longitudinal 
  depressions 
  on 
  the 
  thorax 
  are 
  bounded 
  by 
  

   large 
  rugae, 
  and 
  there 
  are, 
  moreover, 
  a 
  few 
  large 
  punctures 
  and 
  

   some 
  small 
  and 
  slightly 
  raised 
  tubercles 
  on 
  the 
  thorax. 
  The 
  ros- 
  

   trum 
  has 
  a 
  longitudinal 
  groove 
  on 
  each 
  side, 
  and 
  a 
  triangular 
  

   elevated 
  plate 
  at 
  the 
  apex. 
  

  

  EuRYCHiRUS, 
  nov. 
  gen. 
  Molytid^. 
  

   Antennce 
  breviusculae, 
  scapo 
  davato, 
  oculos 
  attingente 
  ; 
  articu- 
  

   lis 
  duobus 
  basalibus 
  funiculi 
  obconicis, 
  reliquis 
  brevibus, 
  sub- 
  

   rotundatis 
  ; 
  clava 
  elongato-ovata, 
  acuminata. 
  Rostrum 
  bre- 
  

   viusculum, 
  capite 
  vix 
  longius, 
  teres, 
  versus 
  apicem 
  sensim 
  

   crassius, 
  supra 
  leviter 
  carinatum. 
  Oculi 
  magni, 
  sub-rotun- 
  

   dati, 
  modice 
  convexi, 
  in 
  fronte 
  sub-approximati. 
  Thorax 
  

   basi 
  apiceque 
  truncatus, 
  convexus, 
  lateribus 
  ante 
  medium 
  

   rotundatus, 
  postice 
  elevato-marginatus. 
  Scutellum 
  triangu- 
  

   lare. 
  Elytra 
  ampla, 
  humeris 
  productis, 
  obtuse 
  angulatis. 
  

   Pedes 
  magni, 
  longi, 
  femoribus 
  pone 
  medium 
  valde 
  incrassatis; 
  

   tibiae 
  apice 
  muticae 
  ; 
  tarsis 
  latis, 
  articulo 
  ultimo 
  crassiusculo, 
  

   biunguiculato. 
  Corpus 
  breve, 
  modice 
  convexum, 
  squamo- 
  

   sum, 
  mediae 
  magnitudinis. 
  

   The 
  rostrum 
  in 
  this 
  genus 
  is 
  very 
  like 
  that 
  of 
  Phytonomus, 
  and 
  

   is 
  a 
  trifle 
  longer 
  in 
  proportion 
  and 
  less 
  thick 
  than 
  in 
  P. 
  punclatus 
  ; 
  

   the 
  head 
  is 
  rather 
  more 
  exserted, 
  and 
  hence 
  the 
  eyes 
  are 
  some- 
  

   what 
  removed 
  from 
  the 
  lateral 
  margin 
  of 
  the 
  thorax, 
  which 
  pre- 
  

   sents 
  no 
  trace 
  of 
  lateral 
  lobe 
  : 
  excepting 
  that 
  the 
  scape 
  is 
  rather 
  

   less 
  thickened, 
  the 
  antennae 
  are 
  very 
  nearly 
  the 
  same 
  — 
  they 
  spring 
  

   from 
  the 
  apex 
  of 
  the 
  rostrum. 
  The 
  eyes 
  are 
  very 
  large, 
  for 
  the 
  

   most 
  directed 
  forwards, 
  and 
  encroach 
  upon 
  the 
  forehead. 
  The 
  

   elytra 
  differ 
  in 
  having 
  the 
  humeral 
  portion 
  more 
  produced, 
  oblique 
  

   at 
  first, 
  then 
  obtusely 
  angular. 
  The 
  legs 
  are 
  remarkably 
  large 
  ; 
  

   the 
  femora 
  very 
  long, 
  and 
  much 
  incrassated 
  : 
  the 
  tarsi 
  are 
  very 
  

   large, 
  the 
  joints 
  much 
  expanded, 
  and 
  differing 
  but 
  little 
  in 
  width 
  ; 
  

   the 
  claw 
  joint 
  is 
  very 
  stout, 
  and 
  provided 
  with 
  moderate 
  sized, 
  

   diverging, 
  simple 
  claws. 
  — 
  1 
  have 
  no 
  hesitation 
  in 
  placing 
  this 
  

   genus 
  in 
  the 
  family 
  Molytides, 
  and 
  near 
  to 
  Hypera.
