   [Genotype: 
  Ophiogostrella 
  maculilhorax 
  Brues.] 
  Monobasic 
  and 
  designated. 
  

  

  Through 
  the 
  kindness 
  of 
  C. 
  T. 
  Brues 
  I 
  have 
  been 
  able 
  to 
  study 
  the 
  

   two 
  paratypes 
  of 
  the 
  genotype, 
  and 
  one 
  of 
  these 
  is 
  now 
  deposited 
  in 
  

   the 
  United 
  States 
  National 
  Museum. 
  

  

  The 
  peculiarly 
  formed 
  apicnl 
  joint 
  of 
  the 
  front 
  tarsus 
  (pi. 
  54, 
  fig. 
  57) 
  

   with 
  its 
  notched 
  lower 
  outer 
  margin 
  and 
  the 
  venation 
  of 
  (he 
  forewing 
  

   (pi. 
  55, 
  fig. 
  75), 
  especially 
  the 
  long 
  narrow 
  stigma 
  with 
  radius 
  near 
  

   base, 
  the 
  strongly 
  curved 
  apicnl 
  abscissa 
  of 
  radius, 
  and 
  the 
  very 
  short 
  

   intercubitus 
  distinguish 
  tliis 
  genus 
  immediately. 
  Brucs 
  described 
  the 
  

   vertex 
  as 
  "not 
  margined 
  behind," 
  but 
  I 
  find 
  that 
  the 
  occipital 
  carina, 
  

   though 
  not 
  stronir, 
  is 
  complete. 
  The 
  second 
  disroidal 
  cell 
  is 
  short 
  

   and 
  broad, 
  with 
  the 
  lower 
  posterior 
  angle 
  shari)ly 
  acute, 
  the 
  ba.se 
  very 
  

   short 
  and 
  the 
  di.scocubitus 
  very 
  strongly 
  curved, 
  but 
  witliout 
  a 
  ramel- 
  

   lus; 
  the 
  nervulus 
  dislinftly 
  antefurcal; 
  the 
  n<'rvellus 
  broken 
  at 
  about 
  

   its 
  lower 
  third. 
  The 
  prep(!ctoral 
  carina 
  is 
  obsolete 
  above 
  and 
  weak 
  

   elsewhere. 
  The 
  speculum 
  is 
  indistinctly 
  defined 
  because 
  of 
  the 
  very 
  

   weak 
  groove 
  and 
  the 
  fact 
  that 
  the 
  entire 
  Tn(>sopl<'uron 
  is 
  poli.^hed; 
  the 
  

   scutellum 
  is 
  carinately 
  margined 
  to 
  apex. 
  Otherwise 
  the 
  genus 
  agrees 
  

   with 
  all 
  the 
  key 
  characters 
  leading 
  to 
  the 
  Ophion 
  group 
  of 
  genera. 
  

  

  The 
  genotype 
  is 
  the 
  smallest 
  (7-8 
  mm. 
  long) 
  species 
  of 
  the 
  Ophionini 
  

   known 
  to 
  mo.
