  Remarkably 
  distinguished 
  in 
  its 
  subfamily 
  by 
  the 
  shape 
  of 
  the 
  

   head; 
  instead 
  of 
  being 
  short, 
  broadly 
  rounded, 
  and 
  bent 
  downwardly 
  

   and 
  posteriorly 
  as 
  usual, 
  the 
  head 
  in 
  Nannocoris 
  is 
  conspicuous^ 
  

   porrect, 
  conical 
  (figs. 
  22-25), 
  with 
  the 
  beak 
  arising 
  from 
  the 
  anterior 
  

   extremity; 
  the 
  beak 
  is 
  longer 
  than 
  in 
  the 
  other 
  genera, 
  reaching 
  the 
  

   hind 
  coxae, 
  the 
  underside 
  of 
  head 
  is 
  grooved 
  (fig. 
  33) 
  and 
  the 
  sterna 
  

   obviously 
  troughlike 
  for 
  its 
  reception. 
  Pronotum 
  with 
  distinct 
  col-

  Pubescence 
  short 
  and
