  Legs 
  subgraiiular, 
  modorately 
  liirsute, 
  the 
  hairs 
  more 
  numerous 
  and 
  

   longer 
  distad; 
  anterior 
  legs 
  of 
  male 
  subcrassate 
  and 
  more 
  densely 
  

   hirsute, 
  the 
  two 
  distal 
  joints 
  with 
  broad 
  pads 
  of 
  dense 
  hairs; 
  these 
  

   pads 
  decrease 
  caudad 
  and 
  are 
  lost 
  at 
  about 
  segment 
  15. 
  No 
  other 
  

   modifications 
  of 
  the 
  male 
  legs 
  could 
  be 
  made 
  out. 
  

  

  Copulatory 
  legs 
  closely 
  similar 
  to 
  those 
  figured 
  by 
  Pocock 
  for 
  the 
  

   next 
  species; 
  more 
  slender, 
  the 
  two 
  apical 
  divisions 
  longer 
  and 
  less 
  

   strongly 
  curved, 
  the 
  four 
  proximal 
  processes 
  not 
  evident. 
  

  

  Color 
  of 
  dried 
  specimen, 
  dark 
  brown, 
  probably 
  nearly 
  black 
  in 
  life; 
  

   clypeus, 
  all 
  the 
  margins 
  of 
  first 
  segment, 
  posterior 
  margin 
  of 
  all 
  other 
  

   segments, 
  carinae, 
  ventral 
  surface, 
  except 
  a 
  large 
  spot 
  below 
  the 
  carinae 
  

   in 
  front, 
  and 
  legs, 
  dull 
  yellowish; 
  in 
  life 
  these 
  parts 
  may 
  have 
  bueu 
  

   bright 
  yellow 
  or 
  red, 
  from 
  the 
  analogy 
  of 
  the 
  related 
  Liberian 
  species, 
  

   H. 
  laetus 
  Cook. 
  

  

  Length 
  about 
  24 
  mm. 
  ; 
  width 
  2.5 
  mm. 
  ; 
  length 
  of 
  antenna 
  nearly 
  5 
  mm. 
  ;

  leg 
  of 
  segmeut 
  14 
  nearly 
  7 
  mm. 
  

  

  This 
  description 
  was 
  taken 
  from 
  the 
  dried 
  male 
  specimen. 
  No. 
  250 
  of 
  

   the 
  Berlin 
  Museum, 
  the 
  true 
  type 
  of 
  the 
  species. 
  It 
  was 
  collected 
  in 
  

   Sennar 
  by 
  Hartmann. 
  

  

  From 
  an 
  alcoholic 
  specimen 
  found 
  later 
  it 
  appears 
  that 
  the 
  processes 
  

   of 
  the 
  sternum 
  of 
  the 
  fourth 
  pair 
  of 
  legs 
  are 
  very 
  slightly 
  developed, 
  

   consisting 
  merely 
  of 
  rounded 
  prominences. 
  This 
  individual 
  was 
  col- 
  

   lected 
  with 
  the 
  type 
  and 
  bears 
  the 
  same 
  number 
  in 
  the 
  Berlin 
  Museum. 
  

  

  HABRODESMUS 
  FLAVOCINCTUS 
  (Pocock.) 
  

  

  Tetracentroaternus 
  fiavocinctus 
  Pocock, 
  Ann. 
  aud 
  Mag.

  Hist. 
  (6),

  p. 
  438,

  1896. 
  

  

  This 
  species 
  may, 
  it 
  would 
  seem, 
  be 
  safely 
  referred 
  to 
  the 
  present 
  

   genus. 
  From 
  the 
  figure 
  of 
  the 
  copulatory 
  legs 
  it 
  appears 
  to 
  occupy 
  a 
  

   position 
  intermediate 
  between 
  the 
  preceding 
  and 
  the 
  following 
  species. 
  

   The 
  measurements 
  are 
  given 
  as 
  27 
  mm. 
  by 
  4.3 
  mm. 
  It 
  is 
  to 
  be 
  pre- 
  

   sumed 
  that 
  this 
  refers 
  to 
  the 
  females, 
  which 
  in 
  the 
  present 
  genus 
  are 
  

   always 
  distinctly 
  more 
  robust 
  than 
  the 
  males 
  and 
  have 
  shorter 
  legs. 
  

  

  • 
  HABRODESMUS 
  MASSAI, 
  new 
  species. 
  

  

  To 
  be 
  distinguished 
  from 
  all 
  previously 
  described 
  species 
  by 
  the 
  sub- 
  

   dentate 
  posterior 
  margins 
  of 
  the 
  segments 
  and 
  the 
  strongly 
  contracted 
  

   copulatory 
  legs. 
  

  

  Head 
  scarcely 
  wider 
  than 
  the 
  first 
  segment; 
  vertex 
  smooth, 
  the 
  sulcus 
  

   very 
  distinct; 
  clypeus 
  sparsely 
  hirsute, 
  the 
  hairs 
  rising 
  from 
  slight 
  

   I)unctations; 
  labrum 
  scarcely 
  emarginate, 
  the 
  teeth 
  distinct. 
  

  

  First 
  segment 
  subelliptic-reniform 
  as 
  in 
  H. 
  hartmanni, 
  laterad 
  with 
  

   a 
  narrow, 
  though 
  distinct, 
  raised 
  margin 
  ; 
  lateral 
  corners 
  even 
  more 
  

   rounded 
  than 
  in 
  H. 
  hartmanni. 
  

  

  Segments 
  smooth 
  with 
  a 
  velvety 
  appearance, 
  scarcely 
  shining, 
  marked 
  

   only 
  by 
  the 
  transverse 
  sulcus 
  which 
  is 
  located 
  slightly 
  behind 
  the 
  middle
