  The

  This 
  species 
  has 
  more 
  resemblance 
  to 
  X 
  Thaxteri, 
  than 
  

   to 
  any 
  other 
  of 
  our 
  known 
  species. 
  It 
  lacks, 
  however, 
  the 
  

   marked 
  contrasts 
  presented 
  in 
  paler 
  ground 
  color, 
  the 
  heavier 
  

   black 
  markings 
  and 
  the 
  red 
  dashed 
  reniform.of 
  that 
  species. 
  

   The 
  black 
  line 
  on 
  the 
  submedian 
  fold 
  is 
  not 
  so 
  long 
  or 
  so 
  

   heavy, 
  and 
  its 
  posterior 
  wings 
  are 
  not 
  so 
  dark. 
  

  

  It 
  resembles 
  more 
  closely 
  the 
  X 
  conformis 
  of 
  Europe, 
  but 
  

   it 
  has 
  not 
  the 
  distinct 
  basilar 
  line, 
  the 
  claviform 
  spot, 
  or 
  the 
  

   broad 
  reniform 
  of 
  that 
  species. 
  Its 
  transverse 
  lines 
  are 
  also 
  

   more 
  sharply 
  angulated, 
  and 
  it 
  is 
  apparently 
  a 
  shorter- 
  

   winged 
  species. 
  

  

  Xylina 
  unimoda 
  n. 
  sp. 
  

  

  Head 
  and

  cinereous. 
  Abdomen

  white 
  scales 
  on 
  costal

   basal 
  regions. 
  Transverse 
  lines

  scarcely 
  visible

  bordered 
  by 
  a 
  darker 
  

   shade. 
  Median 
  band 
  faintly 
  visible, 
  angulated 
  on 
  the 
  lower 
  

   portion 
  of 
  the 
  reniform. 
  Anterior 
  transverse 
  band 
  prominently 
  

   toothed 
  ; 
  the 
  cellular 
  teeth 
  separated 
  from 
  the 
  orbicular 
  ; 
  the 
  

   two 
  small 
  teeth 
  inclosing 
  the 
  submedian 
  fold, 
  with 
  some 
  

   whitish 
  scales 
  interiorly, 
  and 
  outwardly 
  continued 
  in 
  an 
  acute 
  

   claviform 
  mark. 
  Posterior 
  transverse 
  line 
  dentate, 
  removed 
  

   from 
  the 
  reniform.

  obsolete 
  subterminal 
  line 
  preceded 
  by 
  

   intranervular 
  fuscous 
  sagittate 
  spots. 
  Orbicular 
  spot 
  pale 
  

   gray, 
  darker 
  scaled 
  interiorly, 
  either 
  connected 
  with 
  or 
  

   detached 
  from 
  the 
  suborbicular, 
  which 
  is 
  gray-bordered 
  

   above. 
  Eeniform 
  inconspicuous, 
  cinereous, 
  with 
  a 
  black 
  

   border 
  more 
  heavily 
  marked 
  below, 
  and 
  edged 
  within 
  by 
  

   gray. 
  

  

  Secondaries 
  pallid, 
  slightly 
  darker 
  along 
  the 
  margin, 
  with 
  

   paler 
  fringes, 
  which 
  are 
  almost 
  white 
  near 
  the 
  anal 
  angle, 
  a 
  

   distinct 
  cellular 
  spot, 
  and 
  faint 
  median 
  line. 
  

  

  Beneath, 
  secondaries 
  paler 
  than 
  in

  and 
  less 
  

   thickly 
  sprinkled 
  with 
  fuscous 
  scales.
