  fig. 
  33. 
  

  

  Male 
  : 
  Very 
  closely 
  allied 
  to 
  H. 
  analis 
  ; 
  the 
  shape, 
  size, 
  and 
  hind 
  

   legs 
  of 
  the 
  male 
  are 
  also 
  similar, 
  but 
  the 
  vestiture 
  is 
  different 
  ; 
  the 
  

   clypeus 
  is 
  also 
  quadri-dentate, 
  but 
  the 
  two 
  median 
  teeth 
  are 
  

   distinctly 
  smaller 
  than 
  the 
  outer 
  ones 
  ; 
  the 
  median 
  groove 
  of 
  the 
  

   prothorax 
  and 
  the 
  base 
  have 
  a 
  band 
  of 
  flavescent 
  or 
  golden-yellow 
  

   scales 
  ; 
  the 
  scutellum 
  is 
  scaly 
  ; 
  the 
  elytra 
  have 
  two 
  moderately 
  

   raised, 
  yet 
  distinct 
  costse 
  on 
  each 
  side, 
  and 
  four 
  somewhat 
  broad 
  

   bands 
  of 
  rounded, 
  dense, 
  yellow 
  or 
  yellowish 
  scales, 
  the 
  second 
  band 
  

   does 
  not 
  reach 
  quite 
  to 
  the 
  apex, 
  and 
  the 
  fourth 
  coalesces 
  with 
  the 
  

   third 
  at 
  about 
  half 
  the 
  length 
  ; 
  the 
  propygidium 
  and 
  sides 
  of 
  the 
  

   abdomen 
  are 
  very 
  densely 
  scaly 
  and 
  so 
  is 
  the 
  pygidium, 
  the 
  scales 
  

   of 
  which 
  are, 
  however, 
  of 
  a 
  uniform 
  tint. 
  

  

  Female 
  : 
  Densely 
  hairy 
  on 
  the 
  prothorax 
  ; 
  elytra 
  pale 
  testaceous, 
  

   clothed 
  with 
  dense 
  greyish 
  hairs, 
  and 
  having 
  an 
  apical 
  band 
  of 
  

   yellow 
  scales 
  ; 
  pygidium 
  and 
  sides 
  of 
  abdomen 
  covered 
  with 
  light 
  

   orange-yellow 
  scales. 
  

  

  Length 
  4f-5 
  mm.

  width 
  2-J—

  Hob. 
  Cape 
  Colony 
  (Caledon, 
  Eiversdale, 
  Namaqualand). 
  

  

  In 
  the 
  examples 
  from 
  Namaqualand 
  the 
  scales 
  are 
  orange-yellow, 
  

   but 
  much 
  paler 
  in 
  those 
  from 
  other 
  localities.

  Male 
  : 
  Black, 
  with 
  the 
  elytra 
  chestnut-brown 
  and 
  the 
  legs 
  either 
  

   dark 
  brown 
  or 
  black 
  ; 
  clypeus 
  sharply 
  quadri-dentate 
  and 
  with 
  the 
  

   two 
  median 
  teeth 
  only 
  slightly 
  smaller 
  than 
  the 
  outer 
  ; 
  prothorax 
  

   deeply 
  grooved 
  from 
  the 
  median 
  part 
  to 
  the 
  base, 
  densely 
  but 
  some- 
  

   what 
  briefly 
  hairy, 
  the 
  hairs 
  are 
  slightly 
  flavescent 
  and 
  there 
  is 
  

   no 
  basal 
  band 
  of 
  scales 
  in 
  my 
  examples 
  ; 
  scutellum 
  clothed 
  with 
  

   appressed, 
  squamose 
  hairs 
  ; 
  elytra 
  covered 
  with 
  appressed, 
  slightly 
  

   flavescent 
  and 
  squamose 
  hairs 
  which 
  do 
  not 
  hide 
  the 
  colour 
  of 
  the 
  

   background, 
  and 
  having 
  occasionally 
  a 
  narrow 
  apical 
  band 
  of 
  yellow 
  

   scales 
  ; 
  apical 
  part 
  of 
  the 
  propygidium 
  and 
  pygidium 
  with 
  contiguous 
  

   golden-yellow 
  scales, 
  the 
  latter 
  with 
  two 
  darker 
  yellow 
  longitudinal 
  

   patches 
  ; 
  hind 
  legs 
  somewhat 
  robust, 
  trochanters 
  non-spinose, 
  hind 
  

   femora 
  simple, 
  but 
  with 
  the 
  knee 
  somewhat 
  sharply 
  angular 
  on 
  each 
  

   side 
  ; 
  hind 
  tibiae 
  simple, 
  a 
  little 
  compressed 
  inwardly 
  towards 
  the 
  

   apex, 
  and 
  slightly 
  concave 
  there, 
  sharply 
  angular, 
  almost 
  sub- 
  

   mucronate 
  on 
  each 
  side 
  at 
  tip, 
  and 
  with 
  a 
  distinct 
  but 
  short 
  apical 
  

   spur 
  ; 
  hind 
  claws 
  simple, 
  single.
