  (J. 
  Head 
  dark 
  brown, 
  pale 
  above. 
  Thorax 
  and 
  abdomen 
  chestnut, 
  inclin- 
  

   ing 
  to 
  orange. 
  Antennae 
  and 
  feet 
  reddish-brown. 
  Fore 
  wings 
  luteous, 
  palest 
  

   at 
  their 
  margins. 
  At 
  the 
  base 
  is 
  a 
  reddish-brown 
  patch, 
  out 
  of 
  which 
  proceeds 
  

   a 
  silver-white 
  streak, 
  (edged 
  outwardly 
  and 
  inwardly 
  by 
  a 
  narrow 
  black 
  line) 
  

   which 
  for 
  a 
  short 
  distance 
  follows 
  the 
  course 
  of 
  the 
  subcostal 
  nerve, 
  then 
  grad- 
  

   ually 
  widens 
  and 
  touches 
  the 
  interior 
  margin 
  near 
  the 
  middle, 
  spreading 
  thence 
  

   upward 
  and 
  outward 
  toward 
  the 
  anterior 
  angle, 
  but 
  becoming 
  obsolete 
  before 
  

   reaching 
  the 
  extremity, 
  and 
  passing 
  off 
  into 
  irregular 
  black 
  patches 
  with 
  white 
  

   centers. 
  The 
  edges 
  of 
  this 
  streak 
  are 
  very 
  irregular 
  in 
  outline. 
  Near 
  the 
  

   disc 
  is 
  a 
  small 
  and 
  indistinct 
  white 
  spot, 
  edged 
  with 
  black, 
  and 
  another 
  is 
  sit- 
  

   uated 
  near 
  the 
  middle 
  of 
  the 
  interior 
  margin, 
  while 
  the 
  posterior 
  margin 
  is 
  

   marked 
  with 
  a 
  row 
  of 
  black 
  blotches, 
  not 
  extending 
  to 
  the 
  anterior 
  angle. 
  

  

  Secondaries 
  clouded 
  with 
  fuscous 
  at 
  the 
  base, 
  reddish 
  chestnut 
  toward 
  the 
  

   margin, 
  with 
  two 
  fuscous 
  submarginal 
  bands 
  united 
  near 
  the 
  middle 
  to 
  the 
  

   fuscous 
  basal 
  cloud. 
  Fringes 
  of 
  both 
  wings 
  entirely 
  reddish-chestnut. 
  

  

  Under 
  side, 
  pale 
  yellowish-brown, 
  irregularly 
  blotched 
  with 
  fuscous, 
  with 
  the 
  

   white 
  streak 
  of 
  the 
  upper 
  side 
  very 
  imperfectly 
  seen.

  Thauma, 
  uov. 
  gen. 
  

  

  Head 
  small, 
  almost 
  concealed 
  by 
  the 
  long 
  hairs 
  which 
  cover 
  all 
  parts 
  of 
  the 
  

   thorax. 
  Antennae 
  of 
  the 
  $ 
  serrated 
  from 
  base 
  to 
  apex, 
  the 
  serratures 
  largest 
  

   beyond 
  the 
  middle. 
  Palpi 
  very 
  short, 
  concealed. 
  Thorax 
  densely 
  covered 
  

   above 
  and 
  below 
  with 
  long 
  hairs, 
  which 
  extend 
  over 
  the 
  base 
  of 
  the 
  wings. 
  

   Abdomen 
  extending 
  as 
  far 
  as 
  the 
  margin 
  of 
  the 
  hind 
  wings, 
  covered 
  with 
  short 
  

   hairs, 
  and 
  with 
  a 
  short 
  anal 
  tuft. 
  Legs 
  stout 
  and 
  rather 
  short, 
  of 
  almost 
  equal 
  

   thickness 
  throughout 
  their 
  entire 
  length. 
  Middle 
  and 
  hind 
  tarsi 
  five-jointed, 
  

   the 
  last 
  joint 
  receiving 
  and 
  almost 
  concealing 
  the 
  claws. 
  Wings 
  ample, 
  opaque, 
  

   straight 
  in 
  front, 
  slightly 
  curved 
  outwardly 
  toward 
  their 
  tip, 
  and 
  considerably 
  

   rounded 
  on 
  their 
  posterior 
  angles. 
  Discal 
  cell 
  very 
  large, 
  subcostal 
  vein 
  reach- 
  

   ing 
  the 
  costa 
  a 
  little 
  beyond 
  the 
  middle. 
  The 
  nervures 
  are 
  widely 
  separated 
  

   toward 
  the 
  posterior 
  margin, 
  gradually 
  decreasing 
  in 
  the 
  width 
  of 
  their 
  inter- 
  

   spaces 
  as 
  they 
  approach 
  the 
  anterior 
  angle. 
  This 
  genus 
  is 
  in 
  many 
  respects 
  

   allied 
  to 
  Endromis 
  of 
  Europe, 
  but 
  differs 
  somewhat 
  in 
  the 
  neuratiou, 
  and 
  in 
  

   the 
  longer 
  and 
  less 
  pilose 
  abdomen. 
  Perhaps 
  its 
  nearest 
  relations 
  will 
  be 
  found 
  

   in 
  the 
  South 
  American 
  genera 
  Ormiscodes 
  and 
  Podalia.
