  Hardly 
  a 
  true 
  Melissodes, 
  but 
  I 
  find 
  no 
  better 
  genus 
  for 
  it. 
  It 
  will 
  

   be 
  known 
  by 
  the 
  small 
  size, 
  rather 
  short 
  antennae, 
  and 
  white 
  hair 
  

   covering 
  most 
  of 
  abdomen. 
  There 
  is 
  considerable 
  resemblance 
  to 
  

   Tetralonia 
  costaricensis 
  Friese, 
  but 
  the 
  abdomen 
  is 
  different.

  from 
  T. 
  albilabris

   the 
  short 
  hair 
  of 
  thorax; 
  mesonotum 
  with 
  white 
  hair 
  posteriorly, 
  but 
  

   scutellum 
  black 
  with 
  no 
  yellowish 
  hair 
  at 
  sides; 
  tegula 
  black; 
  wings 
  

   grayish, 
  not 
  tinged 
  with 
  yellow; 
  abdomen 
  black, 
  the 
  fourth 
  and 
  fifth 
  

   tergites 
  with 
  some 
  pale 
  hair, 
  but 
  the 
  tergites 
  without 
  testaceous 
  

   margins.
