  Habitat 
  ? 
  ' 
  

  

  I 
  strongly 
  suspect 
  this 
  is 
  a 
  New 
  Holland 
  insect,* 
  but 
  I 
  had 
  no 
  

   habitat 
  with 
  it. 
  In 
  the 
  smaller 
  specimen, 
  which 
  I 
  take 
  to 
  be 
  the 
  

   male, 
  the 
  thorax 
  and 
  elytra 
  are 
  about 
  equal 
  in 
  width, 
  and 
  in 
  the 
  

   larger 
  specimen 
  the 
  elytra 
  are 
  rather 
  broader 
  than 
  the 
  thorax. 
  

   The 
  under 
  parts 
  of 
  the 
  body 
  are 
  very 
  sparingly 
  clothed 
  with 
  

   scales, 
  and 
  are 
  rather 
  finely 
  and 
  irregularly 
  punctured 
  ; 
  on 
  the 
  

   abdominal 
  segments 
  (more 
  especially 
  the 
  terminal 
  segment) 
  are 
  a 
  

   few 
  very 
  minute 
  scattered 
  granules. 
  The 
  scales 
  along 
  the 
  mesial 
  

   line 
  of 
  the 
  thorax 
  are 
  rather 
  paler 
  than 
  on 
  other 
  parts, 
  if 
  we 
  

   except 
  two 
  small 
  spots 
  in 
  the 
  middle 
  of 
  each 
  half. 
  The 
  scales 
  of 
  

   the 
  elytra 
  vary 
  in 
  tint, 
  some 
  being 
  umber 
  brown 
  and 
  others 
  

   brownish 
  yellow; 
  they 
  form 
  small 
  patches 
  of 
  either 
  colour; 
  and 
  

   there 
  are 
  small 
  irregular 
  black 
  markings 
  in 
  parts 
  formed 
  by 
  dark 
  

   scales, 
  but 
  on 
  the 
  sides 
  of 
  the 
  body, 
  where 
  they 
  are 
  most 
  distinct, 
  

   they 
  are 
  seen 
  to 
  be 
  denuded 
  patches. 
  The 
  little 
  rounded 
  tubercles, 
  

   or 
  granules, 
  both 
  on 
  the 
  thorax 
  and 
  elytra, 
  are 
  denuded 
  and 
  glossy. 
  

   The 
  antennae 
  are 
  clothed 
  with 
  black 
  hairs 
  — 
  the 
  scape 
  as 
  well 
  as 
  

   other 
  parts 
  ; 
  and 
  so 
  are 
  the 
  legs.

  • 
  M. 
  Jekel, 
  to 
  whom 
  I 
  have 
  shown 
  this 
  insect 
  (since 
  this 
  paper 
  was 
  read), 
  

   informs 
  me 
  he 
  possesses 
  a 
  species 
  veiy 
  like, 
  if 
  not 
  identical 
  with 
  it, 
  from 
  the 
  Cape 
  

   of 
  Good 
  Hope. 
  It 
  approaches 
  very 
  near 
  to 
  the 
  genus 
  Somatcdes 
  ; 
  indeed, 
  M. 
  Jekel 
  

   had 
  provisionally 
  placed 
  his 
  insect 
  in 
  that 
  genus: 
  we 
  both, 
  however, 
  think 
  that 
  it 
  

   presents 
  characters 
  which 
  render 
  it 
  desirable 
  to 
  form 
  a 
  new 
  genus 
  for 
  its 
  reception.
