  posterior 
  callus 
  distinct, 
  the 
  surface 
  is 
  covered 
  with 
  very 
  short 
  black 
  

   bristles 
  somewhat 
  seriate 
  and 
  longer 
  and 
  stiffer 
  along 
  the 
  suture 
  and 
  

   the 
  outer 
  margins 
  ; 
  the 
  two 
  apical 
  outer 
  teeth 
  of 
  the 
  anterior 
  tibiae 
  are 
  

   not 
  connate, 
  and 
  the 
  three 
  are 
  nearly 
  equi-distant 
  ; 
  in 
  the 
  male 
  the 
  

   hind 
  tibiae 
  are 
  only 
  moderately 
  thickened 
  in 
  comparison 
  with 
  the 
  

   previously 
  described 
  species, 
  not 
  being 
  thicker 
  than 
  the 
  thighs, 
  they 
  

   are 
  somewhat 
  strangulate 
  at 
  apex, 
  and 
  simple 
  ; 
  basal 
  joints 
  of 
  tarsi 
  

   triangular, 
  fifth

  preceding, 
  and 
  slightly 
  tri- 
  

   dentate 
  beneath 
  ; 
  claw 
  a 
  little 
  shorter

  Pachycnema

  n. 
  spec. 
  

  

  This 
  species 
  greatly 
  resembles 
  P. 
  marginella, 
  but 
  differs 
  in 
  the 
  

   colour 
  which 
  is 
  opaque 
  black 
  in 
  the 
  male 
  with 
  the 
  propygidium, 
  

   pygidium 
  and 
  abdomen 
  clothed 
  with 
  white 
  scales, 
  and 
  reddish 
  brown 
  

   on 
  the 
  elytra 
  in 
  the 
  female 
  with 
  the 
  pygidium 
  and 
  abdomen 
  yellow 
  ; 
  

   there 
  is 
  a 
  faint 
  trace 
  of 
  a 
  scaly 
  band 
  in 
  the 
  anterior 
  part 
  of 
  the 
  sides 
  

   of 
  the 
  prothorax, 
  but 
  no 
  scaly 
  patches 
  or 
  spots 
  on 
  the 
  disk, 
  and 
  in 
  the 
  

   elytra 
  the 
  bristles 
  of 
  the 
  sutural 
  and 
  marginal 
  rows 
  are 
  much 
  longer 
  ; 
  

   in 
  the 
  female 
  the 
  elytra 
  are 
  more 
  distinctly 
  tri-sulcate 
  longitudinally 
  

   on 
  each 
  side 
  ; 
  hind 
  legs 
  similar 
  in 
  both 
  sexes.

  Shape 
  and 
  sculpture 
  of 
  P. 
  marginella 
  and 
  P. 
  moerens 
  from 
  which 
  

   it 
  differs 
  in 
  the 
  colour 
  of 
  the 
  elytra, 
  which 
  are 
  lighter 
  brick- 
  

   red, 
  and 
  occasionally 
  narrowly 
  infuscate 
  along 
  the 
  outer 
  margin, 
  and 
  

   in 
  the 
  scales 
  on 
  the 
  propygidium 
  and 
  pygidium 
  being 
  whiter 
  in 
  the 
  

   male, 
  there 
  is 
  no 
  trace 
  of 
  scales 
  on 
  the 
  discoidal 
  part 
  of 
  the 
  prothorax, 
  

   and 
  they 
  are 
  even 
  as 
  often 
  as 
  not 
  obliterated 
  along 
  the 
  outer 
  margins 
  

   in 
  both 
  sexes, 
  but 
  the 
  distinctive 
  character 
  consists 
  in 
  the 
  very 
  long 
  

   and 
  dense 
  villosity 
  covering 
  the 
  prothorax, 
  and 
  the 
  longer 
  but 
  less 
  

   dense 
  black 
  or 
  flavescent 
  bristly 
  hairs 
  clothing 
  the 
  elytra 
  ; 
  in 
  most 
  

   females 
  there 
  are 
  on 
  the 
  elytra 
  some 
  very 
  fine, 
  appressed 
  yellowish 
  

   but 
  closely 
  set 
  scales.
