  dark 
  discal 
  patch 
  extending 
  from 
  the 
  base 
  to 
  the 
  top 
  of 
  the 
  declivity 
  and 
  outwardly 
  

   as 
  far 
  as 
  stria 
  4, 
  the 
  scaling 
  there 
  being 
  dark 
  brown 
  slightly 
  variegated 
  with 
  grey 
  ; 
  

   the 
  sternum 
  with 
  rather 
  thin 
  fulvous 
  scaling 
  laterally 
  and 
  denser 
  paler 
  scales 
  in 
  the 
  

   middle 
  ; 
  the 
  venter 
  with 
  very 
  sparse 
  whitish 
  setiform 
  scales. 
  

  

  Head 
  with 
  coarse 
  confluent 
  punctation 
  that 
  is 
  not 
  obscured 
  by 
  the 
  scaling, 
  the 
  

   intervals 
  between 
  the 
  punctures 
  becoming 
  sharp 
  and 
  prominent 
  on 
  the 
  forehead; 
  

   the 
  scales 
  fulvous 
  and 
  narrow, 
  becoming 
  noticeably 
  broader 
  on 
  the 
  middle 
  line 
  ; 
  at 
  

   the 
  junction 
  with 
  the 
  rostrum 
  a 
  shallow 
  transverse 
  depression 
  containing 
  a 
  deep 
  

   median 
  fovea, 
  and 
  a 
  faint 
  broad 
  impression 
  above 
  each 
  eye. 
  Rostrum 
  stout, 
  cylin- 
  

   drical, 
  moderately 
  curved, 
  longer 
  than 
  the 
  prothorax 
  in 
  both 
  sexes, 
  slightly 
  dilated 
  

   at 
  the 
  apex, 
  rugosely 
  punctate 
  and 
  five-carinate 
  a 
  far 
  as 
  the 
  antennae, 
  the 
  outer 
  

   carinae 
  being 
  less 
  distinct 
  and 
  undulating 
  and 
  the 
  apical 
  area 
  closely 
  punctate 
  in 
  

   both 
  sexes. 
  Antennae 
  inserted 
  at 
  about 
  one-fourth 
  from 
  the 
  apex 
  in 
  the 
  $ 
  and 
  about 
  

   one-third 
  in 
  the 
  $ 
  ; 
  joint 
  2 
  of 
  the 
  funicle 
  a 
  little 
  shorter 
  than 
  1. 
  Prothorax 
  

   subconical, 
  transverse, 
  gradually 
  narrowed 
  from 
  the 
  base 
  to 
  beyond 
  the 
  middle, 
  

   then 
  more 
  rapidly 
  so, 
  the 
  sides 
  gently 
  rounded 
  and 
  shallowly 
  constricted 
  near 
  the 
  

   apex 
  ; 
  the 
  basal 
  margin 
  shallowly 
  bisinuate, 
  the 
  median 
  dorsal 
  lobe 
  broadly 
  sub- 
  

   truncate 
  at 
  the 
  apex 
  ; 
  the 
  dorsum 
  finely 
  coriaceous, 
  unevenly 
  set 
  with 
  large 
  punctures, 
  

   which 
  are 
  deepest 
  and 
  most 
  numerous 
  in 
  the 
  dark 
  basal 
  triangle 
  and 
  towards 
  the 
  

   sides 
  ; 
  a 
  low 
  boss-like 
  elevation 
  in 
  the 
  middle 
  of 
  the 
  disk, 
  from 
  the 
  top 
  of 
  which 
  a 
  

   low 
  carina 
  runs 
  to 
  the 
  front 
  margin 
  ; 
  the 
  scales 
  narrow 
  and 
  elongate, 
  interspersed 
  

   on 
  the 
  fulvous 
  area 
  with 
  white 
  scale-like 
  recumbent 
  setae, 
  which 
  are 
  blackish 
  on 
  

   the 
  dark 
  area. 
  Scutellum 
  oval, 
  longer 
  than 
  broad, 
  with 
  confluent 
  shallow 
  punctation 
  

   and 
  fulvous 
  setiform 
  scales. 
  Elytra 
  broad, 
  subtriangular, 
  broadest 
  at 
  the 
  roundly 
  

   angulate 
  shoulders, 
  with 
  regular 
  rows 
  of 
  large 
  distant 
  punctures, 
  the 
  distances 
  

   between 
  them 
  being 
  as 
  long 
  as 
  the 
  punctures 
  themselves, 
  which 
  become 
  much 
  shallower 
  

   on 
  the 
  posterior 
  declivity 
  ; 
  the 
  intervals 
  broader 
  than 
  the 
  punctures 
  and 
  finely 
  

   rugulose, 
  3, 
  5, 
  7 
  and 
  9 
  being 
  carinate 
  and 
  the 
  others 
  flat 
  ; 
  the 
  carina 
  on 
  3 
  

   much 
  higher 
  than 
  the 
  others 
  and 
  deeply 
  interrupted 
  before 
  the 
  middle 
  and 
  more 
  

   broadly 
  so 
  behind 
  the 
  middle, 
  the 
  other 
  carinae 
  complete 
  ; 
  the 
  scales 
  on 
  the 
  dark 
  

   area 
  rather 
  narrower 
  and 
  less 
  dense 
  than 
  on 
  the 
  fulvous 
  parts, 
  the 
  intervals 
  with 
  a 
  

   row 
  of 
  recumbent 
  scale-like 
  white 
  setae, 
  and 
  each 
  puncture 
  containing 
  a 
  white 
  seta. 
  

   Legs 
  rugulose, 
  with 
  fairly 
  dense 
  fulvous 
  scales 
  intermingled 
  with 
  white 
  setae 
  ; 
  the 
  

   femora 
  each 
  with 
  a 
  single 
  stout 
  tooth 
  ; 
  the 
  front 
  and 
  hind 
  tibiae 
  rather 
  sharply 
  

   angulate 
  externally 
  at 
  the 
  apex 
  ; 
  the 
  tarsal 
  claws 
  with 
  a 
  rather 
  long 
  sharp 
  tooth. 
  

   Sternum 
  : 
  the 
  mesosternum 
  hollowed 
  and 
  with 
  a 
  low 
  prominence 
  on 
  each 
  side 
  between 
  

   the 
  middle 
  coxae, 
  the 
  side-pieces 
  finely 
  aciculate, 
  opaque, 
  and 
  closely 
  and 
  coarsely 
  

   punctate 
  ; 
  the 
  metasternum 
  shiny, 
  with 
  numerous 
  fine 
  punctures 
  and 
  scattered 
  

   large 
  ones, 
  and 
  with 
  a 
  strong 
  oblique 
  ridge 
  between 
  the 
  mid 
  and 
  hind 
  coxae. 
  Venter 
  

   very 
  shallowly 
  punctate, 
  except 
  at 
  the 
  base 
  of 
  the 
  first 
  and 
  apex 
  of 
  the 
  last 
  visible 
  

   ventrite, 
  the 
  latter 
  being 
  longer 
  and 
  flatter 
  in 
  the 
  j 
  1 
  than 
  in 
  the 
  $. 
  

  

  Length, 
  5-75-7 
  mm. 
  ; 
  breadth, 
  3-5-4 
  mm. 
  

  

  Brazil 
  : 
  Bahia 
  (G. 
  Bondar). 
  

  

  Described 
  from 
  four 
  specimens. 
  

  

  This 
  species 
  is 
  very 
  closely 
  allied 
  to 
  C. 
  dimidiatus 
  , 
  Champ., 
  from 
  Central 
  America, 
  

   but 
  the 
  latter 
  differs 
  in 
  the 
  following 
  particulars 
  : 
  — 
  the 
  mesosternum 
  is 
  quite 
  flat 
  

   between 
  the 
  middle 
  coxae 
  ; 
  the 
  metasternum 
  is 
  as 
  coarsely 
  and 
  closely 
  punctate 
  

   as 
  the 
  mesosternum 
  ; 
  the 
  middle 
  portion 
  of 
  the 
  carina 
  on 
  interval 
  three 
  is 
  much 
  

   less 
  elevated 
  and 
  the 
  carina 
  on 
  five 
  is 
  evanescent 
  on 
  its 
  basal 
  third 
  ; 
  the 
  shoulders 
  

   are 
  less 
  sharply 
  angulated, 
  etc. 
  

  

  Dr. 
  Bondar 
  has 
  found 
  this 
  insect 
  attacking 
  the 
  fruits 
  of 
  the 
  guava 
  (Psidium 
  

   guayava), 
  though 
  the 
  nature 
  of 
  the 
  injury 
  is 
  not 
  indicated.
