  Plate

  Made 
  up 
  of 
  species 
  formerly 
  included 
  in 
  Ceresa 
  Amyot 
  and 
  Serville 
  

   and 
  Stictocephala 
  Stal 
  but 
  differing 
  from 
  both 
  genera 
  by 
  the 
  reduction 
  

   in 
  size 
  of 
  the 
  male 
  styles 
  and 
  the 
  highly 
  modified 
  aedeagus. 
  The 
  

   members 
  of 
  this 
  group 
  are 
  relatively 
  small 
  compact 
  species 
  that 
  have 
  

   the 
  suprahumerals 
  prominent 
  and 
  frequently 
  developed 
  into 
  small 
  

   horns. 
  

  

  Pronotum 
  low; 
  suprahumerals 
  usually 
  very 
  prominent, 
  small 
  horns 
  

   sometimes 
  present; 
  metopidium 
  broad, 
  rounded 
  transversely 
  and 
  

   posteriorly. 
  Teeth 
  on 
  lateral 
  valves 
  as 
  long 
  as 
  narrowest 
  width 
  of 
  

   valves; 
  arising 
  near 
  ventral 
  margins 
  of 
  valves. 
  Styles 
  of 
  male 
  with 
  

   apical 
  portion 
  broad, 
  flat, 
  slightly 
  lunate; 
  apices 
  obtuse. 
  Aedeagus 
  

   usually 
  with 
  functional 
  orifice 
  apical; 
  knob 
  or 
  flaphke 
  extension 
  present 
  

   on 
  apical 
  margin 
  above 
  orifice 
  usually 
  small 
  but 
  sometimes 
  greatly 
  

   enlarged 
  or 
  variously 
  modified. 
  

  

  Type 
  of 
  the 
  genus, 
  Membracis 
  festina 
  Say 
  (1830, 
  p. 
  243), 
  originally 
  

   described 
  from 
  Florida, 
  is 
  one 
  of 
  the 
  most 
  common, 
  abundant, 
  and 
  

   weD 
  known 
  species 
  occiu-ring 
  in 
  the 
  southern 
  sections 
  of 
  the 
  United 
  

   States. 
  Several 
  varieties 
  have 
  been 
  established 
  on 
  characters 
  of 
  

   color 
  and 
  form 
  of 
  the 
  suprahumerals, 
  but 
  these 
  characters 
  are 
  grada- 
  

   tional 
  and 
  do 
  not 
  warrant 
  varietal 
  consideration. 
  The 
  type 
  specimen 
  

   has 
  been 
  lost 
  and 
  a 
  neotype 
  is 
  designated.

  mm. 
  General 
  color

  meeting

   body; 
  suprahumerals

  Teeth 
  of 
  lateral 
  valves 
  arising 
  from 
  center 
  of 
  lower 
  third 
  of 
  valves, 
  

   flattened

  ventrally 
  and 
  convergent

  Sternal 
  

   plate 
  with 
  shallow 
  apical 
  notch.

  semilunate, 
  obtuse 
  apically.

   apical 
  flap

  orifice 
  which 
  opens
