  having 
  in 
  addition 
  a 
  supra-marginal 
  costule, 
  they 
  are 
  finely 
  coriaceous, 
  

   and 
  very 
  densely 
  hairy, 
  but 
  these 
  hairs 
  are 
  sometimes 
  wanting 
  on 
  the 
  

   costas 
  at 
  regular 
  intervals, 
  and 
  gives 
  thus 
  to 
  the 
  elytra 
  a 
  sub-tessellated 
  

   appearance 
  ; 
  pygidium 
  broad, 
  vertical 
  in 
  both 
  sexes. 
  

  

  In 
  the 
  male 
  the 
  slightly 
  squamulose 
  hairs 
  are 
  denser 
  than 
  in 
  the 
  

   female, 
  and 
  the 
  latter 
  has 
  an 
  apical 
  spur 
  to 
  all 
  the 
  legs.

  Spec. 
  

  

  Male 
  : 
  Colour, 
  sculpture, 
  and 
  vestiture 
  of 
  C. 
  tessellata 
  ; 
  the 
  head 
  

   and 
  clypeus 
  are 
  similar, 
  but 
  the 
  prothorax 
  is 
  more 
  angular 
  laterally 
  

   at 
  middle 
  and 
  more 
  obliquely 
  attenuated 
  thence 
  towards 
  the 
  basal 
  

   angle 
  ; 
  the 
  elytra 
  are 
  much 
  more 
  plainly 
  tri-costate 
  on 
  each 
  side, 
  

   and 
  the 
  intervals 
  are 
  deeper, 
  but 
  the 
  minute 
  scale-like 
  hairs 
  are 
  

   identical.

  CONGELLA 
  VALIDA, 
  n. 
  spec. 
  

  

  Eeddish 
  brown, 
  sometimes 
  slightly 
  infuscate 
  ; 
  head 
  with 
  scattered 
  

   granules, 
  clypeus 
  parabolic 
  but 
  a 
  little 
  blunt 
  at 
  the 
  tip 
  ; 
  prothorax 
  as 
  

   in 
  the 
  preceding 
  species, 
  but 
  the 
  space 
  among 
  the 
  scar-like 
  punc- 
  

   tures 
  are 
  plainly 
  wrinkled 
  or 
  rugose 
  ; 
  the 
  elytra 
  are 
  similarly 
  costate, 
  

   the 
  hairs 
  are 
  not 
  so 
  dense, 
  but 
  longer 
  and 
  less 
  squamulose, 
  and 
  

   the 
  sculpture 
  consists 
  of 
  contiguous 
  impressed 
  punctures 
  having 
  in 
  

   ibhe 
  centre 
  a 
  smaller 
  one 
  emitting 
  a 
  hair 
  ; 
  these 
  hairs 
  are 
  similar 
  

   on 
  the 
  upper 
  and 
  under 
  sides 
  and 
  also 
  on 
  the 
  legs 
  as 
  well 
  as 
  on 
  the 
  

   pygidium, 
  the 
  latter 
  is 
  granulose 
  and 
  has 
  a 
  median 
  longitudinal 
  

   furrow 
  ; 
  in 
  the 
  male 
  the 
  legs 
  have 
  no 
  apical 
  spur, 
  but 
  in 
  the 
  female 
  

   the 
  four 
  posterior 
  legs 
  are 
  provided 
  with 
  one. 
  

  

  Length 
  11-12^- 
  mm. 
  ; 
  width 
  6J 
  mm. 
  

  

  This 
  species 
  is 
  much 
  more 
  massive 
  than 
  C. 
  tessellatula, 
  and 
  the 
  

   vestiture 
  is 
  not 
  much 
  denser 
  in 
  the 
  male 
  than 
  in 
  the 
  female.

  Spec. 
  

  

  Intermediate 
  in 
  size 
  between 
  C. 
  tessellatula 
  and 
  C. 
  valida 
  ; 
  the 
  

   colour 
  is 
  black 
  on 
  the 
  upper 
  side, 
  piceous 
  red 
  underneath, 
  and 
  

   the 
  prothorax 
  and 
  elytra 
  bear 
  minute, 
  scattered, 
  greyish 
  appressed 
  

   hairs 
  ; 
  the 
  shape 
  and 
  sculpture 
  of 
  the 
  head 
  are 
  the 
  same 
  as 
  in 
  

   C. 
  valida, 
  but 
  on 
  the 
  prothorax 
  the 
  cicatricose 
  punctures 
  are 
  deeper 
  ;
