  and 
  touching 
  tlie 
  posterior 
  point 
  of 
  the 
  sternal 
  keel 
  ;

  plate 
  

   heart-shaped,

  The 
  anal 
  plate 
  in 
  this 
  specimen 
  is 
  raised 
  so 
  as 
  to 
  exhibit 
  the 
  

   more 
  internal 
  generative 
  organs 
  (fig. 
  6«), 
  as 
  is 
  also 
  frequently 
  the 
  

   case 
  in 
  Acanthosoma 
  ; 
  in 
  some 
  species 
  of 
  which 
  genus 
  {A.forfex, 
  m. 
  

   VLX\A 
  elongatnm,m.), 
  the 
  crescent-shaped 
  dorsal 
  plate 
  (a*) 
  attains 
  

   a 
  very 
  great 
  development. 
  The 
  same 
  thing 
  takes 
  place 
  in 
  several 
  

   instances 
  in 
  the 
  males 
  of 
  the 
  Urostylidce. 
  

  

  Family 
  UROSTYLID^. 
  

  

  The 
  next 
  insect 
  that 
  I 
  propose 
  to 
  describe 
  belongs 
  to 
  a 
  group 
  

   which 
  includes 
  insects 
  presenting 
  such 
  singular 
  characters 
  as 
  to 
  

   render 
  their 
  location 
  in 
  any 
  of 
  the 
  great 
  groups 
  of 
  Heriiiptera 
  a 
  

   matter 
  of 
  some 
  difficulty. 
  Mr. 
  Westwood, 
  who, 
  in 
  1837, 
  first 
  

   described 
  three 
  of 
  the 
  species 
  comprised 
  in 
  it, 
  placed 
  them 
  at 
  the 
  

   end 
  of 
  Mr. 
  Hope's 
  Catalogue 
  of 
  Sciitelleridce 
  (^Scutati, 
  Burm.), 
  

   and 
  this 
  is 
  probably 
  as 
  nearly 
  as 
  possible 
  their 
  true 
  position. 
  

   Mr. 
  White, 
  in 
  1839, 
  in 
  describing 
  (Mag. 
  Nat. 
  Hist. 
  N.S. 
  iii. 
  543, 
  

   and 
  Ent. 
  Trans,

  []

  ) 
  a 
  new 
  species 
  belonging 
  to 
  tiie 
  

   group, 
  under 
  the 
  name 
  of 
  CalUprepes 
  Grayii, 
  considers 
  it 
  to 
  be 
  

   allied 
  to 
  Cajisus 
  ; 
  and 
  Dr. 
  Herrich 
  Schaffer, 
  in 
  the 
  same 
  year 
  

   (1839), 
  in 
  describing 
  one 
  of 
  the 
  species 
  described 
  in 
  Hope's 
  

   Catalogue, 
  under 
  the 
  new 
  name 
  of 
  Typhlocor'is 
  semicircularis, 
  re- 
  

   gards 
  it 
  also 
  as 
  belonging 
  to 
  the 
  Capsini, 
  in 
  which 
  family, 
  he 
  says, 
  

   if 
  we 
  do 
  not 
  consider 
  the 
  structure 
  of 
  the 
  elytra 
  as 
  one 
  of 
  its 
  

   characters, 
  it 
  may 
  form 
  a 
  peculiar 
  group, 
  the 
  character 
  of 
  which 
  

   would 
  be, 
  " 
  Membrane 
  with 
  several 
  distinct 
  longitudinal 
  nervures; 
  

   corium 
  without 
  an 
  appendix." 
  As, 
  however, 
  the 
  essential 
  cha- 
  

   racter 
  of 
  the 
  Capsini 
  is 
  derived 
  from 
  the 
  structure 
  of 
  the 
  elytra, 
  

   it 
  w^ould 
  be 
  manifestly 
  absurd 
  to 
  admit 
  into 
  that 
  family 
  a 
  group 
  

   which 
  was 
  distinguished 
  by 
  not 
  possessing 
  that 
  character. 
  The 
  

   error 
  in 
  both 
  these 
  cases 
  arose 
  from 
  the 
  authors 
  referred 
  to 
  possess- 
  

   ing 
  only 
  mutilated 
  specimens 
  of 
  species 
  of 
  the 
  genus 
  Urolabida, 
  in 
  

   which 
  the 
  ocelli 
  are 
  wanting, 
  giving 
  them 
  to 
  a 
  certain 
  extent 
  a 
  more 
  

   doubtful 
  character 
  than 
  properly 
  belongs 
  to 
  them. 
  In 
  the 
  ninth 
  

   volume 
  of 
  the 
  Wanzenartigen 
  Insecten, 
  Dr. 
  Herrich 
  Schaffer 
  re- 
  

   curs 
  to 
  his 
  genus 
  Typhlocor'is 
  ; 
  and 
  whilst 
  quoting 
  as 
  synonymous 
  

   with 
  it, 
  Mr. 
  Westwood's 
  genus 
  Urostylis, 
  which 
  he 
  must 
  have 
  

   known 
  had 
  five 
  joints 
  in 
  its 
  antennae, 
  places 
  it 
  " 
  without 
  doubt" 
  

   amongst 
  the 
  Ccecigeni 
  of 
  Amyot 
  and 
  Serville, 
  in 
  which 
  the 
  number 
  

   of 
  joints 
  never 
  exceeds 
  four, 
  and 
  from 
  which 
  it 
  differs 
  in 
  all 
  its 
  

   characters 
  quite 
  as 
  much 
  as 
  from 
  the 
  Capsini.
