  A 
  single 
  specimen 
  was 
  found 
  on 
  the 
  leeward 
  side 
  of 
  the 
  island. 
  

  

  In 
  respect 
  to 
  form 
  of 
  body 
  and 
  longitudinal 
  direction 
  of 
  veins 
  on 
  the 
  

   hemelytra 
  this 
  insect 
  bears 
  some 
  relation 
  to 
  Hypselosoma, 
  Reuter 
  ; 
  but 
  in 
  all 
  

   other 
  respects 
  it 
  seems 
  sufficiently 
  different 
  to 
  constitute 
  a 
  separate 
  genus 
  

   [p. 
  160]. 
  

  

  It 
  is 
  evident 
  that 
  Oncerodes 
  is 
  closely 
  related 
  to 
  Corixidea, 
  but 
  

   the 
  forewing 
  is 
  more 
  coriaceous, 
  the 
  venation 
  slightly 
  different, 
  the 
  

   ocelli 
  are 
  indistinguishable 
  in 
  the 
  type, 
  and 
  the 
  scutellum 
  is 
  smaller 
  

   than 
  in 
  Corixidea. 
  It 
  is 
  possible 
  that 
  a 
  brachypterous 
  specimen 
  

   of 
  Corixidea 
  might 
  present 
  some 
  of 
  the 
  peculiarities 
  of 
  Oncerodes, 
  

   but 
  meantime 
  it 
  appears 
  advisable 
  to 
  regard 
  the 
  latter 
  as 
  distinct 
  

   pending 
  the 
  acquisition 
  of 
  more 
  material. 
  In 
  none 
  of 
  the 
  specimens 
  

   of 
  Corixidea 
  examined 
  by 
  us 
  is 
  there 
  any 
  indication 
  of 
  an 
  abbrevia- 
  

   tion 
  of 
  the 
  fore 
  wings.

  The 
  original 
  description 
  : 
  

  

  OMMATIDES, 
  gen. 
  nov. 
  

  

  Coleopterine, 
  closely 
  resembling 
  a 
  short 
  thick 
  Geocoris. 
  Eyes 
  very 
  large, 
  

   oval, 
  projecting 
  diagonally 
  against 
  the 
  anterior 
  corner 
  of 
  the 
  pronotum 
  ; 
  front 
  

   of 
  the 
  head 
  short, 
  bluntly 
  tumid, 
  with 
  the 
  face 
  vertical, 
  protracted 
  downward, 
  

   and 
  having 
  long 
  lobate 
  cheeks 
  which 
  converge 
  over 
  the 
  base 
  of 
  the 
  rostrum 
  ; 
  

   antennse 
  filiform 
  beyond 
  the 
  second 
  joint, 
  the 
  basal 
  joint 
  shorter 
  than 
  and 
  a 
  

   little 
  thicker 
  than 
  the 
  second 
  ; 
  rostrum 
  thick 
  at 
  base, 
  short, 
  tapering, 
  quite 
  

   slender 
  toward 
  the 
  tip, 
  reaching 
  almost 
  to 
  the 
  middle 
  coxae. 
  Pronotum 
  very 
  

   short, 
  almost 
  annular, 
  with 
  the 
  sides 
  rounded 
  off 
  anteriorly 
  to 
  admit 
  the 
  form 
  

   of 
  the 
  eyes, 
  the 
  posterior 
  margin 
  almost 
  straight. 
  The 
  two 
  forward 
  pairs 
  of 
  

   legs 
  placed 
  near 
  together; 
  the 
  anterior 
  tibiae 
  greatly 
  thickened 
  at 
  tip 
  and 
  

   armed 
  with 
  long 
  spines. 
  Scutellum 
  very 
  short, 
  transverse, 
  triangular. 
  

   Hemelytra 
  high 
  convex, 
  extending 
  amply 
  over 
  the 
  abdomen 
  and 
  much 
  longer 
  

   than 
  it 
  ; 
  the 
  costal 
  border 
  moderately 
  curved, 
  with 
  the 
  middle 
  areole 
  

   moderately 
  wide, 
  and 
  the 
  thick 
  cubital 
  vein 
  running 
  back 
  parallel 
  with 
  the 
  

   next 
  inner 
  vein 
  all 
  the 
  way 
  to 
  tip 
  of 
  membrane, 
  and 
  with 
  the 
  two 
  exterior 
  

   transverse 
  veins 
  as 
  in 
  ScMzoptera.

  with 
  the 
  pronotum, 
  scutellum, 
  and 
  

   a 
  broad 
  band 
  behind 
  the

  the 
  membrane, 
  blue-black. 
  The 
  

   bead 
  reddish 
  brown 
  above, 
  yellow

  polished, 
  stout, 
  bright 
  yellow, 
  

   remotely 
  hairy. 
  Pronotum 
  moderately 
  arched, 
  opaque, 
  a 
  little 
  scabrous. 
  

   Hemelytra 
  thick, 
  opaque, 
  velvety; 
  the 
  tiembrane 
  but 
  little 
  thinner 
  than 
  the
