  We 
  are 
  not 
  in 
  ignorance 
  of 
  what 
  has 
  been 
  said 
  5 
  in 
  favor 
  of 
  re- 
  

   garding 
  Ploiariodes 
  and 
  Ploiariola 
  as 
  distinct 
  genera, 
  but 
  we 
  find 
  

   the 
  chief 
  character 
  advanced 
  for 
  their 
  separation, 
  namely 
  the 
  lateral 
  

   carina 
  of 
  pronotum, 
  showing 
  practically 
  all 
  phases 
  from 
  distinct 
  to 
  

   obsolete. 
  6 
  Even 
  were 
  this 
  character 
  unequivocal 
  we 
  should 
  regard 
  

   it 
  of 
  no 
  more 
  than 
  subgeneric 
  value 
  in 
  view 
  of 
  the 
  agreement 
  

   throughout 
  the 
  species 
  in 
  general 
  coloration 
  and 
  habitus 
  as 
  well 
  

   as 
  in 
  the 
  venation 
  of 
  the 
  forewings 
  and 
  the 
  structure 
  of 
  the 
  fore 
  

   legs. 
  All 
  species 
  known 
  to 
  us 
  have 
  the 
  legs 
  and 
  antennae 
  as 
  well 
  

   as 
  the 
  beak 
  with 
  blackish 
  spots 
  or 
  annuli, 
  and 
  the 
  wings 
  are 
  in- 
  

   variably 
  dark 
  spotted. 
  The 
  head 
  and 
  thorax 
  have 
  silvery 
  hairs, 
  usu- 
  

   ally 
  arranged 
  in 
  distinct 
  lines, 
  some 
  of 
  these 
  being 
  almost 
  invaria- 
  

   bly 
  evident 
  on 
  pleura 
  and 
  pectus. 
  The 
  pronotum 
  is 
  more 
  or 
  less 
  

   distinctly 
  vittate, 
  at 
  least 
  behind 
  the 
  constriction 
  but 
  there 
  are 
  

   some 
  differences 
  in 
  this 
  respect 
  which 
  are 
  used 
  in 
  defining 
  a 
  few 
  of 
  

   the 
  species; 
  the 
  carina 
  on 
  side 
  of 
  pronotum 
  is 
  nearly 
  always 
  pale. 
  

   The 
  abdomen 
  usually 
  is 
  dark, 
  with 
  the 
  spiracles 
  and 
  spots 
  on 
  con- 
  

   nexivum 
  pale, 
  the 
  venter 
  finely 
  pubescent, 
  with 
  more 
  or 
  less 
  of 
  

   the 
  median 
  line, 
  and 
  sometimes 
  spots 
  about 
  bases 
  of 
  certain 
  

   longer 
  hairs, 
  bare. 
  

  

  The 
  radial 
  vein 
  runs 
  to 
  beyond 
  the 
  middle 
  of 
  the 
  fore 
  wing, 
  end- 
  

   ing 
  in 
  the 
  costa, 
  the 
  apical 
  portion 
  of 
  it 
  being 
  what 
  we 
  have 
  called 
  

   the 
  " 
  stigma 
  " 
  which 
  offers 
  some 
  good 
  distinguishing 
  characters 
  for 
  

   the 
  species 
  both 
  in 
  its 
  shape 
  and 
  color. 
  The 
  pronotum 
  is 
  divided 
  into 
  

   two 
  parts 
  by 
  a 
  broad 
  constriction, 
  the 
  anterior 
  part 
  being 
  about 
  half 
  

   as 
  long 
  as 
  the 
  posterior, 
  but 
  there 
  are 
  no 
  species 
  known 
  to 
  us 
  in 
  

   which 
  the 
  pronotum 
  is 
  at 
  all 
  pedicillate. 
  All 
  species 
  have 
  the 
  meso- 
  

   notum 
  and 
  metanotum, 
  and 
  usually 
  the 
  basal 
  abdominal 
  tergite 
  with 
  

   a 
  slender 
  thorn 
  on 
  the 
  middle 
  of 
  the 
  hind 
  margin; 
  the 
  presence 
  or 
  

   absence 
  of 
  a 
  process, 
  on 
  middle 
  of 
  hind 
  margin 
  of 
  the 
  pronotum 
  is 
  a 
  

   specific 
  character. 
  The 
  spines 
  or 
  bristles 
  on 
  fore 
  femora 
  are 
  some- 
  

   times 
  difficult 
  to 
  see 
  even 
  with 
  a 
  high 
  power 
  lens.

  • 
  We 
  have 
  examined 
  several 
  species 
  from 
  the 
  Oceanic 
  region 
  in 
  addition 
  to 
  those 
  

   treated 
  herein.
