  Dr. 
  Coppinger 
  obtained 
  at 
  Eagle 
  Island, 
  in 
  the 
  Amirante 
  group, 
  

   some 
  Curculionidao 
  belonging 
  to 
  the 
  genus 
  Cratopus, 
  The 
  species 
  

   of 
  this 
  genus 
  are 
  found 
  in 
  the 
  island 
  of 
  Johanna, 
  in 
  Bourbon, 
  Mau- 
  

   ritius, 
  and 
  Rodriguez. 
  Species 
  have 
  also 
  been 
  described 
  from 
  India 
  

   and 
  the 
  Cape 
  of 
  Good 
  Hope, 
  which 
  appear 
  to 
  belong 
  to 
  the 
  genus. 
  

   I 
  have 
  not 
  yet 
  seen 
  any 
  species 
  from 
  Madagascar. 
  

  

  As 
  the 
  species 
  from 
  Eagle 
  Island 
  appears 
  to 
  be 
  undescribed, 
  I 
  

   propose 
  to 
  call 
  it 
  Cratopus 
  adsjjersus. 
  

  

  Cratopus 
  adspersus. 
  

  

  Oblongo-ovatus, 
  nigro-piceus, 
  pube 
  brevissima 
  grisea 
  vestitus, 
  gut- 
  

   tulis 
  minutis 
  cuprascentibus 
  irregularibus 
  adspersus 
  ; 
  thorace 
  

   antice 
  fortiter, 
  postice 
  paulo 
  angustato, 
  lateribus 
  rotundatis 
  ; 
  

   Bcutello 
  pube 
  pallida 
  dense 
  vestito 
  ; 
  elytris 
  ad 
  apiccra 
  modice 
  

   acuminatis, 
  punctato-striatis, 
  interstitiis 
  fere 
  planis 
  ; 
  femo- 
  

   ribus 
  anticis 
  subtus 
  ante 
  apicem 
  dente 
  minuto 
  instructis. 
  

   Long. 
  41 
  lin., 
  lat. 
  2 
  lin. 
  

  

  Head 
  finely 
  granulose, 
  with 
  a 
  very 
  slight 
  fovea 
  between 
  the 
  eyes. 
  

   The 
  eyes 
  not 
  very 
  prominent, 
  nearly 
  round, 
  only 
  very 
  slightly 
  oval. 
  

   Antennte 
  pitchy, 
  not 
  very 
  long, 
  moderately 
  stout 
  ; 
  the 
  first 
  joint 
  of 
  

   the 
  funiculus 
  about 
  three 
  times 
  as 
  long 
  as 
  broad 
  ; 
  the 
  second 
  joint 
  

   twice 
  as 
  long 
  as 
  broad 
  ; 
  the 
  following 
  joints 
  only 
  a 
  trifle 
  longer 
  than 
  

   broad. 
  Thorax 
  convex, 
  finely 
  granulose, 
  much 
  narrowed 
  in 
  front, 
  

   distinctly 
  narrowed 
  at 
  the 
  base, 
  the 
  sides 
  much 
  rounded 
  ; 
  the 
  

   pubescence 
  very 
  fine 
  and 
  sparse, 
  but 
  closer 
  at 
  the 
  posterior 
  angles, 
  

   where 
  it 
  forms 
  a 
  pale 
  spot. 
  Scutellum 
  oblong, 
  pale 
  sandy 
  white. 
  

   Elytra 
  distinctly 
  broader 
  than 
  the 
  thorax, 
  rather 
  ample, 
  gradually 
  

   (but 
  not 
  much) 
  widened 
  posteriorly 
  for 
  two 
  thirds 
  their 
  length, 
  not 
  

   quite 
  four 
  times 
  as 
  long 
  as 
  the 
  thorax, 
  obliquely 
  acuminate 
  at 
  tlie 
  

   apex 
  ; 
  the 
  apical 
  margins 
  finely 
  serrate. 
  Tlie 
  strife 
  are 
  very 
  distinct, 
  

   the 
  intervals 
  flat 
  and 
  finely 
  granulose 
  ; 
  the 
  pubescence 
  is 
  fine 
  (not 
  

   sufiicient 
  to 
  cover 
  entirely 
  the 
  under 
  colour 
  of 
  the 
  surface), 
  but 
  there 
  

   is 
  an 
  admixture 
  of 
  less 
  fine 
  slightly 
  coppery 
  pubescence, 
  which 
  gives 
  

   the 
  elytra 
  a 
  speckled 
  appearance. 
  

  

  JIab. 
  Eagle 
  Island, 
  Amirante 
  Islands. 
  

  

  This 
  species 
  resembles 
  C. 
  alhoscuteUatus, 
  Bohem., 
  in 
  general 
  form, 
  

   but 
  is 
  a 
  much 
  shorter 
  insect, 
  and 
  has 
  the 
  thorax 
  more 
  narrowed 
  at 
  

   the 
  base, 
  &c. 
  

  

  The 
  only 
  other 
  Coleopterous 
  Insects 
  found 
  in 
  Eagle 
  Island 
  were 
  

   Dermestes 
  felinus, 
  Eabr., 
  and 
  Opatrum 
  micans, 
  Germar, 
  both 
  common 
  

   and 
  widely 
  distributed 
  species.
