  Head 
  broader 
  than 
  anterior 
  segments, 
  though 
  nearly 
  equaled 
  by 
  the 
  

   first. 
  

  

  Vertex 
  smooth, 
  the 
  sulcus 
  distinct, 
  but 
  not 
  deep; 
  clypeus 
  smooth, 
  

   sparsely 
  hirsute 
  below. 
  

  

  First 
  segment 
  sabelliptic, 
  nearly 
  straight 
  in 
  the 
  middle 
  in 
  front, 
  

   slightly 
  and 
  broadly 
  emarginate 
  behind, 
  the 
  lateral 
  corners 
  rounded. 
  

  

  Segments 
  dorsally 
  smooth 
  except 
  for 
  a 
  very 
  distinct 
  transverse 
  sulcus 
  

   near 
  the 
  middle 
  of 
  the 
  posterior 
  subsegment, 
  beginning 
  on 
  the 
  fifth 
  

   segment* 
  and 
  not 
  distinct 
  on 
  segments 
  18-20. 
  

  

  Lateral 
  cariuae 
  distinct 
  on 
  all 
  the 
  segments 
  except 
  the 
  first 
  and 
  the 
  

   lust 
  two; 
  carinae 
  of 
  second 
  segment 
  somewhat 
  oblique, 
  extending 
  con- 
  

   si<lerably 
  below 
  the 
  lateral 
  corners 
  of 
  the 
  first 
  segment, 
  their 
  posterior 
  

   corners 
  produced 
  somewhat 
  more 
  than 
  on 
  other 
  segments; 
  posterior 
  

   corners 
  of 
  carinae 
  of 
  all 
  segments 
  distinctly, 
  though 
  slightly, 
  produced 
  

   beyond 
  the 
  jiosterior 
  margin 
  ; 
  carinae 
  defined 
  above 
  by 
  a 
  distinct 
  groove, 
  

   while 
  below 
  they 
  are 
  distinct 
  only 
  in 
  front; 
  the 
  poriferous 
  face 
  is 
  flat- 
  

   tened 
  and 
  strongly 
  deflected 
  so 
  that 
  the 
  pores 
  face 
  nearly 
  laterad; 
  on 
  

   anterior 
  segments 
  the 
  pores 
  are 
  located 
  about 
  halfway 
  between 
  the 
  

   line 
  of 
  the 
  transverse 
  sulcus 
  and 
  the 
  posterior 
  margin; 
  on 
  posterior 
  

   segments 
  they 
  are 
  gradually 
  nearer 
  to 
  the 
  posterior 
  corner, 
  which 
  

   becomes 
  more 
  pointed 
  and 
  produced 
  to 
  the 
  nineteenth, 
  where 
  the 
  carina 
  

   is 
  obsolete 
  and 
  the 
  pore 
  is 
  located 
  in 
  a 
  small 
  depression. 
  

  

  Transverse 
  sulcus 
  deep, 
  very 
  distinct 
  and 
  abrupt 
  on 
  the 
  anterior 
  

   side, 
  not 
  creiiulate. 
  

  

  Last 
  segment 
  smooth, 
  tapering 
  gradually 
  to 
  the 
  narrow 
  truncate 
  apex 
  

   which 
  bears 
  four 
  setiferous 
  punctations 
  of 
  which 
  the 
  lower 
  pair 
  is 
  

   much 
  larger 
  and 
  farther 
  apart 
  than 
  the 
  upper. 
  

  

  Anal 
  valves 
  sparsely 
  rugulose, 
  apparently 
  smooth 
  and 
  shining; 
  two 
  

   pairs 
  of 
  fine 
  bristles 
  borne 
  on 
  broad 
  rounded 
  prominences, 
  both 
  dis- 
  

   tinct 
  from 
  the 
  prominent 
  thin 
  margins. 
  

  

  Preanal 
  scale 
  subtriangular, 
  the 
  apex 
  rounded. 
  

  

  Sterna 
  with 
  a 
  distinct 
  conic 
  process 
  at 
  the 
  base 
  of 
  each 
  leg; 
  these 
  

   processes 
  decrease 
  in 
  size 
  cephalad; 
  sternum 
  of 
  fourth 
  pair 
  of 
  legs 
  

   with 
  a 
  small 
  process 
  the 
  shape 
  of 
  which 
  can 
  not 
  be 
  seen 
  without 
  injury 
  

   to 
  the 
  dried 
  specimen.
