  Frontal

  The 
  female 
  from 
  Grenada 
  here 
  described, 
  with 
  shorter 
  pronotal 
  

   tubercles,

  with 
  elevations 
  on 
  the 
  hind 
  margins 
  of 
  tergites 
  4-6, 
  

   and 
  other 
  differences, 
  may 
  well 
  be 
  a 
  species 
  distinct 
  from 
  the 
  true 
  

   angulata 
  of 
  St. 
  Vincent. 
  However, 
  settlement 
  of 
  this 
  question 
  may 
  

   well 
  await 
  the 
  availability 
  of 
  more 
  material. 
  

  

  APPENDIX

  GENOTYPES 
  OF 
  THE 
  FABRICIAN 
  GENERA. 
  

  

  Certain 
  authors 
  claim 
  that 
  Fabricius 
  indicated 
  types 
  of 
  various 
  

   hemipterous 
  genera 
  by 
  repeating 
  generic 
  characters 
  in 
  the 
  specific 
  

   descriptions 
  of 
  the 
  so-called 
  genotypes. 
  Much 
  is 
  made 
  also 
  of 
  the 
  

   fact 
  that 
  in 
  most 
  cases 
  some 
  of 
  the 
  phrases 
  in 
  these 
  descriptions 
  begin 
  

   with 
  italicized 
  words. 
  

  

  In 
  examining 
  these 
  claims 
  it 
  will 
  be 
  well 
  to 
  state 
  the 
  historical 
  

   background 
  of 
  the 
  case. 
  Of 
  the 
  various 
  early 
  authors 
  credited 
  with 
  

   the 
  selection 
  of 
  genotypes 
  in 
  Hemiptera, 
  Latreille 
  (Considerations 
  

   generates, 
  etc., 
  1810) 
  is 
  the 
  only 
  one 
  who 
  asserts 
  his 
  definite 
  inten- 
  

   tion 
  (l'indication 
  de 
  Pespece 
  qui 
  leur 
  sert 
  de 
  type) 
  and 
  who 
  consist- 
  

   ently 
  names 
  only 
  a 
  single 
  species 
  to 
  a 
  genus. 
  Lamarck 
  and 
  Laporte 
  

   frequently 
  .cite 
  more 
  than 
  one 
  species 
  to 
  a 
  genus 
  and 
  are 
  only 
  credited 
  

   with 
  fixing 
  types 
  when 
  they 
  happen 
  to 
  name 
  just 
  one 
  illustration 
  of 
  

   a 
  genus. 
  Now 
  it 
  is 
  clear 
  that 
  using 
  the 
  term 
  in 
  the 
  modern 
  sense
