  MEMBRACIOIDES, 
  new 
  genus 
  

  

  Pronotum 
  produced 
  posteriorly 
  in 
  a 
  median 
  lobe 
  which 
  extends 
  to 
  

   middle 
  of 
  clavus 
  thus 
  entirely 
  concealing 
  the 
  scutellum 
  (fig.

  ; 
  

   the 
  sides 
  of 
  the 
  process 
  are 
  decidedly 
  concave, 
  and 
  the 
  apex 
  mod- 
  

   erately 
  pointed; 
  there 
  is 
  a 
  distinct 
  median 
  impressed 
  line 
  from 
  

   anterior 
  margin 
  of 
  pronotum 
  nearly 
  to 
  apex 
  of 
  the 
  posterior 
  pro- 
  

   longation. 
  Suture 
  between 
  propleurum 
  and 
  pronotum 
  running 
  

   straight 
  back 
  behind 
  eye; 
  inner 
  posterior 
  angle 
  of 
  metapleurum 
  

   produced 
  as 
  a 
  rounded 
  lobe; 
  venation 
  as 
  in 
  Corixidea 
  (fig.
