  Anal 
  valves 
  nearly 
  smooth, 
  the 
  bristles 
  borne 
  on 
  slight 
  prominences 
  

   located 
  near 
  the 
  sloping 
  margins. 
  

  

  Preanal 
  scale 
  broadly 
  subtriangular, 
  the 
  apex 
  truncate. 
  

  

  Sterna 
  with 
  conic 
  processes 
  much 
  larger 
  at 
  the 
  base 
  of 
  the 
  posterior 
  

   leg 
  of 
  each 
  segment; 
  these 
  processes 
  are 
  smaller 
  on 
  the 
  posterior 
  seg- 
  

   ments 
  and 
  do 
  not 
  appear 
  on 
  the 
  anterior. 
  

  

  Sternum 
  of 
  fourth 
  pair 
  of 
  legs 
  with 
  a 
  broad, 
  prominent, 
  hirsute, 
  

   entire 
  process 
  which 
  is 
  strongly 
  flattened 
  antero-postically 
  ; 
  sternum 
  of 
  

   sixth 
  pair 
  of 
  legs 
  with 
  a 
  broadly 
  conic 
  median 
  process. 
  

  

  Legs 
  long 
  and 
  slender, 
  rather 
  sparsely 
  hirsute 
  with 
  short 
  hairs, 
  more 
  

   numerous 
  and 
  longer 
  distad; 
  anterior 
  legs 
  of 
  male 
  slightly 
  crassate, 
  

   the 
  two 
  distal 
  joints 
  with 
  pads 
  of 
  dense 
  hairs, 
  and 
  the 
  second 
  and 
  third 
  

   joints 
  with 
  the 
  ventral 
  face 
  smooth 
  and 
  membraneous 
  or 
  fleshy. 
  

  

  Copulatory 
  legs 
  with 
  a 
  subconic 
  prominence 
  on 
  the 
  lateral 
  face 
  of 
  the 
  

   basal 
  hairy 
  part; 
  above 
  strongly 
  thickened 
  and 
  then 
  abruptly 
  narrowed 
  

   into 
  a 
  slender 
  strongly 
  curved 
  and 
  distally 
  divided 
  process, 
  which 
  turns 
  

   laterad 
  upon 
  itself 
  instead 
  of 
  lying 
  across 
  its 
  fellow, 
  as 
  in 
  other 
  species 
  

   of 
  the 
  i^resent 
  group. 
  

  

  Color 
  of 
  alcoholic 
  specimens 
  brown, 
  a 
  median 
  band 
  of 
  chestnut, 
  

   broadened 
  at 
  each 
  transverse 
  sulcus; 
  on 
  either 
  side 
  of 
  this 
  is 
  an 
  area 
  

   of 
  light 
  brown, 
  and 
  then 
  an 
  equal 
  longitudinal 
  band 
  of 
  very 
  dark 
  

   brown 
  or 
  black, 
  extending 
  to 
  the 
  level 
  of 
  the 
  pores; 
  below 
  this 
  the 
  

   anterior 
  subsegments 
  have 
  a 
  series 
  of 
  brown 
  spots, 
  while 
  the 
  surface 
  

   is 
  elsewhere 
  very 
  light, 
  becoming 
  nearly 
  white 
  below. 
  Basal 
  joints 
  of 
  

   legs 
  white, 
  the 
  distal 
  brown 
  ; 
  antennae 
  dark 
  brown.

  The 
  process 
  of 
  the 
  sternum 
  of 
  the 
  fourth 
  pair 
  of 
  legs 
  differs 
  from 
  

   that 
  of 
  Phaeodesmiis 
  loiujipes 
  in 
  being 
  broader, 
  not 
  so 
  strongly 
  chiti- 
  

   nized, 
  less 
  prominent 
  and 
  hirsute 
  over 
  its 
  entire 
  surface. 
  

  

  The 
  color 
  pattern, 
  while 
  somewhat 
  different 
  from 
  Scolodesmus, 
  resem- 
  

   bles 
  that 
  form 
  rather 
  than 
  Habrodesmus, 
  there 
  being 
  no 
  transverse 
  band 
  

   of 
  bright 
  color.

  Body 
  rather
