   Eremnus 
  fulleri, 
  sp. 
  no 
  v. 
  (fig.

  <J 
  $. 
  Colour 
  piceous, 
  with, 
  dense 
  light 
  earthy-brown 
  scaling, 
  usually 
  with 
  a 
  very 
  

   variable 
  and 
  often 
  indistinct 
  mottling 
  of 
  greyish 
  and 
  blackish 
  scales 
  ; 
  the 
  thorax 
  

   with 
  three 
  indistinct 
  paler 
  stripes. 
  

  

  Head 
  very 
  convex, 
  separated 
  from 
  the 
  rostrum 
  by 
  a 
  broad, 
  shallow 
  impression, 
  

   the 
  finely 
  rugose 
  sculpturing 
  quite 
  hidden 
  by 
  the 
  scaling 
  ; 
  forehead 
  evidently 
  narrower 
  

   than 
  the 
  rostrum 
  and 
  with 
  no 
  central 
  fovea. 
  Rostrum 
  stout, 
  about 
  three-fourths 
  

   the 
  length 
  of 
  the 
  prothorax, 
  almost 
  straight 
  and 
  parallel-sided 
  ; 
  a 
  broad 
  groove 
  

   running 
  backwards 
  on 
  each 
  side 
  from 
  the 
  scrobe 
  to 
  the 
  eye, 
  so 
  that 
  the 
  centra] 
  dorsal 
  

   area 
  is 
  left 
  as 
  a 
  broad 
  parallel-sided 
  ridge 
  with 
  a 
  shallow 
  impression 
  in 
  the 
  middle 
  ; 
  

   the 
  genae 
  broadly 
  impressed 
  below 
  the 
  scrobe 
  . 
  Antennae 
  with 
  the 
  scape 
  rather 
  slender 
  

   and 
  gradually 
  clavate, 
  clothed 
  with 
  dense 
  scaling 
  and 
  appressed 
  setae 
  ; 
  the 
  funicle 
  

   with 
  joint 
  2 
  very 
  slightly 
  longer 
  than 
  1. 
  Prothorax 
  evidently 
  broader 
  than 
  long, 
  

   especially 
  in 
  the 
  $, 
  the 
  greatest 
  width 
  behind 
  the 
  middle, 
  the 
  sides 
  strongly 
  rounded, 
  

   with 
  a 
  broad 
  shallow 
  constriction 
  at 
  the 
  apex, 
  which 
  is 
  much 
  narrower 
  than 
  the 
  base, 
  

   the 
  dorsal 
  apical 
  margin 
  straight, 
  the 
  ocular 
  lobes 
  slight 
  and 
  with 
  very 
  short 
  vibrissae.

  Scutellum 
  minute, 
  with 
  dense 
  pale 
  scaling. 
  Elytra 
  broadly 
  ovate 
  in 
  the 
  <j>, 
  narrower 
  

   and 
  more 
  pointed 
  behind 
  in 
  the 
  <J, 
  the 
  basal 
  margin 
  rather 
  deeply 
  sinuate 
  ; 
  the 
  striae 
  

   and 
  their 
  shallow 
  punctures 
  almost 
  entirely 
  concealed 
  by 
  the 
  dense 
  scaling, 
  the 
  

   intervals 
  almost 
  plane, 
  each 
  with 
  a 
  single 
  row 
  of 
  suberect 
  scale-like 
  setae, 
  interval 
  7 
  

   with 
  a 
  very 
  short 
  elevated 
  carina 
  at 
  the 
  base 
  which 
  prevents 
  the 
  7th 
  stria 
  from 
  

   reaching 
  the 
  base 
  and 
  causes 
  it 
  to 
  turn 
  outwards 
  into 
  the 
  8th 
  ; 
  the 
  scales 
  are 
  small, 
  

   nearly 
  circular, 
  and 
  slightly 
  imbricated. 
  Legs 
  densely 
  clothed 
  with 
  pale 
  scales 
  and 
  

   with 
  broad 
  recumbent 
  setae, 
  the 
  femora 
  without 
  a 
  tooth.

  The 
  only 
  other 
  species 
  of 
  Eremnus 
  with 
  untoothed 
  femora 
  which 
  has 
  a 
  similar 
  

   humeral 
  callus 
  is 
  E. 
  humeralis, 
  Fahr., 
  which 
  can 
  readily 
  be 
  distinguished 
  from 
  

   E. 
  fulleri, 
  among 
  other 
  characters, 
  by 
  the 
  presence 
  of 
  small 
  tubercles 
  at 
  the 
  sides 
  of
