  Genotype. 
  — 
  HylotasteUa 
  schwarsi, 
  new 
  species. 
  

  

  This 
  genus 
  resembles 
  a 
  small 
  species 
  of 
  Hylotastes 
  Bonvouloir, 
  but 
  

   it 
  differs 
  from 
  that 
  genus 
  in 
  being 
  gradually 
  narrowed 
  posteriorly 
  

   and 
  in 
  having 
  the 
  antenna 
  cylindrical 
  and 
  four-fifths 
  as 
  long 
  as 
  the 
  

   body, 
  the 
  clypeus 
  broadly 
  rounded 
  in 
  front, 
  the 
  posterior 
  coxa 
  

   abruptly 
  expanded 
  internally, 
  the 
  propleural 
  triangle 
  longer 
  than 
  

   wide, 
  the 
  tips 
  of 
  the 
  elytra 
  conjointly 
  broadly 
  rounded, 
  and 
  the 
  last 
  

   abdominal 
  tergite 
  not 
  extending 
  over 
  the 
  last 
  abdominal 
  sternite.
