  This 
  species 
  is 
  known 
  from 
  one 
  female 
  only, 
  the 
  type, 
  from 
  CapetUlo, 
  

   Guatemala, 
  collected 
  also 
  by 
  Champion, 
  which 
  is 
  in 
  the 
  British 
  Mu- 
  

   seum 
  (Natural 
  History). 
  It 
  is 
  smaller 
  than 
  the 
  preceding 
  species 
  

   (8.5 
  mm.) 
  ; 
  the 
  apical 
  segment 
  of 
  the 
  maxUlary 
  palpus 
  is 
  smaller, 
  and 
  

   triangular 
  instead 
  of 
  cultriform. 
  The 
  color 
  is 
  pale 
  testaceous. 
  The 
  

   costae 
  and 
  suture 
  are 
  conspicuous, 
  and 
  each 
  has 
  an 
  indistinct, 
  inter- 
  

   rupted 
  row 
  of 
  fine 
  oblong 
  streaks 
  on 
  either 
  side.

  characters. 
  — 
  The 
  dark 
  orange 
  pronotum 
  with 
  a 
  median 
  and 
  

   two 
  lateral 
  spots 
  is 
  unique 
  among 
  the 
  species 
  of 
  this 
  genus. 
  It 
  is 
  the 
  

   largest 
  known 
  species 
  in 
  the 
  genus 
  and 
  is 
  most 
  closely 
  related 
  to 
  V. 
  

   sordidus 
  but 
  has 
  the 
  orange 
  markings 
  which 
  are 
  lacking 
  in 
  that 
  species.
