  the 
  antennae. 
  The 
  branch 
  

   issuing 
  from 
  the 
  second 
  transverse 
  cubital 
  nervure 
  is 
  short 
  ; 
  

   the 
  abdominal 
  segments 
  are 
  smooth 
  without 
  any 
  striations 
  

   as 
  in 
  Microdes 
  ; 
  the 
  furrow 
  on 
  the 
  mesopleurae 
  is 
  wide 
  and 
  

   deep, 
  and 
  obscurely 
  marked 
  with 
  keels.

  This 
  genus 
  is 
  divided 
  into 
  two 
  sections, 
  according 
  to 
  

   the 
  neuration 
  of 
  the 
  anterior 
  wings.

  The 
  two 
  species 
  here 
  described 
  may 
  be 
  separated 
  as 
  

   follows 
  : 
  

  

  (a) 
  The 
  recurrent 
  nervure 
  received 
  opposite 
  the 
  end 
  of 
  

   the 
  basal 
  abscissa 
  of 
  the 
  radius 
  ; 
  the 
  depression 
  at 
  the 
  

   base 
  of 
  the 
  median 
  segment 
  indistinct, 
  triangular; 
  the 
  

   middle 
  lobe 
  of 
  the 
  mesonotum 
  fuscous 
  ; 
  the 
  basal 
  trans- 
  

   verse 
  keel 
  on 
  the 
  median 
  segment 
  indistinct. 
  

  

  O. 
  fuscomaculatus. 
  

  

  (b) 
  The 
  recurrent 
  nervure 
  received 
  distinctly 
  in 
  front 
  

   of 
  the 
  end 
  of 
  the 
  basal 
  abscissa 
  of 
  the 
  radius 
  ; 
  the 
  

   depression 
  at 
  the 
  base 
  of 
  the 
  median 
  segment 
  large, 
  deep, 
  

   semicircular 
  ; 
  the 
  basal 
  transverse 
  keel 
  distinct; 
  the 
  orbits 
  

   and 
  vertex 
  broadly 
  yellow. 
  O. 
  areolatus. 
  

  

  Ophion 
  fuscomaculatus, 
  sp. 
  nov.

  This 
  species 
  agrees 
  with
