  conic 
  spines, 
  narrower 
  and 
  more 
  pointed 
  tlian 
  tliose 
  of 
  other 
  genera, 
  

   and 
  tlie 
  earinae 
  are 
  more 
  produced 
  and 
  more 
  acutely 
  pointed 
  than 
  

   elsewhere, 
  exceeding- 
  in 
  this 
  respect 
  Cncmodcsmus, 
  which 
  consider- 
  

   ably 
  surjiasses 
  Hahrodesmus, 
  where 
  the 
  middle 
  segments 
  have 
  the 
  

   earinae 
  not 
  produced.

  of 
  processes 
  on 
  the 
  third 
  joints 
  of 
  

   legs 
  5

  Head 
  slightly 
  broader 
  than 
  the 
  first 
  segment; 
  vertex 
  even, 
  sulcus 
  

   fine, 
  broader 
  below; 
  clypeus 
  even, 
  sparsely 
  hirsute 
  with 
  short 
  hairs. 
  

  

  First 
  segment 
  subreniform, 
  the 
  lateral 
  margin 
  raised 
  and 
  defined 
  by 
  

   a 
  distinct 
  j^roove. 
  

  

  Second 
  segment 
  slightly 
  broader 
  than 
  the 
  first, 
  as 
  in 
  Hdbrodesmus 
  

   laetus; 
  its 
  posterior 
  corner 
  produced 
  into 
  a 
  distinct 
  rounded 
  lobe. 
  

  

  Segments 
  dorsally 
  smooth, 
  but 
  scarcely 
  shining, 
  transverse 
  sulcus 
  

   beginning 
  from 
  the 
  fifth 
  segment; 
  fine, 
  not 
  deep, 
  obsolete 
  from 
  the 
  

   sixteenth 
  segment. 
  

  

  Lateral 
  carinas 
  distinct, 
  considerably 
  more 
  prominent 
  than 
  in 
  Huhro- 
  

   desmus 
  laetus, 
  the 
  corners 
  j)roduced 
  on 
  all 
  segments 
  beyond 
  the 
  pos- 
  

   terior 
  margin 
  as 
  a 
  distinct 
  triangular 
  j^rocess. 
  Viewed 
  from 
  the 
  side, 
  

   the 
  earinae 
  appear 
  equally 
  distinct 
  from 
  those 
  of 
  the 
  si^ecies 
  mentioned, 
  

   being 
  narrower 
  and 
  much 
  more 
  produced 
  and 
  pointed. 
  On 
  poreless 
  

   segments 
  they 
  are 
  much 
  reduced, 
  but 
  still 
  distinctly 
  exceeding 
  the 
  

   margin, 
  as 
  is 
  also 
  the 
  case 
  on 
  posterior 
  segments, 
  including 
  the 
  nine- 
  

   teenth. 
  

  

  Transverse 
  constriction 
  rather 
  long, 
  distinct 
  and 
  moderately 
  deep, 
  

   not 
  crenulate. 
  

  

  Last 
  segment 
  smooth 
  to 
  near 
  the 
  apex, 
  where 
  it 
  is 
  abruptly 
  narrowed; 
  

   apex 
  subcylindrical, 
  truncate. 
  

  

  Anal 
  valves 
  sparsely 
  rugulose, 
  the 
  setae 
  borne 
  on 
  minute 
  tubercles 
  

   rather 
  remote 
  from 
  the 
  distinctly 
  compressed 
  and 
  rather 
  prominent 
  

   margins. 
  

  

  Preanal 
  scale 
  subtriangular, 
  rounded, 
  with 
  two 
  small 
  setiferous 
  tuber- 
  

   cles 
  distinct 
  from 
  the 
  margin. 
  

  

  Sterna 
  with 
  a 
  distinct, 
  shari)ly 
  conic 
  process 
  at 
  the 
  bases 
  of 
  the 
  

   posterior 
  legs 
  of 
  each 
  segment. 
  At 
  the 
  bases 
  of 
  tlfe 
  anterior 
  pair 
  are 
  

   much 
  smaller 
  processes; 
  sternum 
  of 
  the 
  fourth 
  legs 
  of 
  male 
  with 
  a 
  very 
  

   prominent, 
  antero-postically 
  flattened 
  process, 
  which 
  is 
  slightly 
  nar- 
  

   rowed 
  on 
  the 
  sides 
  at 
  base 
  and 
  has 
  its 
  distal 
  edge 
  strongly 
  chitinized, 
  

   of 
  a 
  brown 
  color, 
  naked 
  and 
  slightly 
  notched 
  in 
  the 
  middle. 
  

  

  Legs 
  distinctly 
  more 
  slender 
  than 
  those 
  of 
  Hahrodesmvs 
  laetus 
  and 
  

   somewhat 
  more 
  sparsely 
  hirsute; 
  anterior 
  legs 
  of 
  male 
  Avith 
  pads 
  of 
  

   dense 
  hairs 
  ; 
  third 
  joint 
  of 
  legs 
  four 
  and 
  five 
  of 
  male 
  with 
  a 
  subappressed, 
  

   spiniform 
  process 
  from 
  the 
  ventral 
  face 
  of 
  the 
  distal 
  part 
  of 
  the 
  third
