  D. 
  testacens,

  was 
  described 
  upon 
  a 
  single 
  female 
  

   example 
  from 
  Lake 
  Superior", 
  and 
  I 
  am 
  not 
  aM'are 
  of 
  any 
  

   subsequent 
  records 
  of 
  its 
  occurrence. 
  

  

  D. 
  lesnei, 
  sp. 
  n., 
  resembles 
  D. 
  concoJor, 
  Newm., 
  but 
  is 
  

   pitchy 
  brown 
  in 
  colour. 
  The 
  eyes 
  in 
  the 
  (J 
  are 
  separated 
  

   by 
  a 
  space 
  about 
  as 
  wide 
  as 
  the 
  thickness 
  of 
  the 
  second 
  joint 
  

   of 
  the 
  antennae. 
  The 
  thorax 
  is 
  fully 
  as 
  long 
  as 
  broad, 
  

   broadest 
  about 
  the 
  middle, 
  becoming 
  slightly 
  narrower 
  

   towards 
  the 
  base, 
  which 
  is 
  sharpl}' 
  margined 
  and 
  more 
  

   rapidly 
  narrower 
  to 
  the 
  apex 
  ; 
  the 
  disc 
  is 
  nitid, 
  clothed 
  with 
  

   a 
  scanty 
  pubescence, 
  with 
  a 
  slight 
  median 
  depression 
  before 
  

   the 
  base. 
  The 
  el^ftra 
  are 
  subparallel, 
  with 
  the 
  lateral 
  margins 
  

   visible 
  from 
  above 
  for 
  the 
  posterior 
  three-quarters 
  of 
  their 
  

   length 
  ; 
  they 
  are 
  moderately 
  nitid, 
  punctate, 
  with 
  a 
  thin 
  

   pubescence 
  and 
  slight 
  indications 
  of 
  longitudinal 
  furrows 
  as 
  

   in 
  D.

   Aug. 
  1909 
  [E. 
  Gallois) 
  ; 
  environs 
  ot 
  Tokio 
  {J. 
  Harmand, 
  

   1906). 
  Communicated 
  by 
  the 
  Paris 
  Museum. 
  

  

  It 
  is 
  curious 
  that 
  a 
  species 
  of 
  this 
  genus 
  should 
  at 
  last 
  have 
  

   been 
  discovered 
  in 
  Japan, 
  since 
  the 
  two 
  Japanese 
  species 
  

   ascribed 
  to 
  it 
  by 
  Mr. 
  Lewis 
  belong 
  to 
  a 
  distinct 
  genus 
  

   {Pseudodendroides, 
  gen. 
  nov.). 
  

  

  PSEUDODENDROIDES, 
  gCU. 
  nOV. 
  

  

  Differs 
  from 
  Dendroides, 
  Latr., 
  in 
  the 
  less 
  parallel, 
  more 
  

   depressed 
  form, 
  in 
  the 
  denser 
  puncturation 
  and 
  pubescence 
  of 
  

   the 
  elytra, 
  and 
  in 
  the 
  much 
  stouter 
  antennae, 
  of 
  which 
  the 
  

   branches 
  in 
  tlie 
  ^ 
  are 
  not 
  exceptionally 
  long 
  and 
  slender. 
  

   From 
  Pseudodendruides, 
  Pic, 
  whicii 
  it 
  more 
  closely 
  resembles, 
  

   it 
  may 
  at 
  once 
  be 
  separated 
  by 
  the 
  large 
  eyes, 
  approximate 
  

   above 
  in 
  the 
  ^ 
  . 
  (Type, 
  P. 
  niponensis, 
  Lew.) 
  

  

  The 
  species 
  placed 
  here, 
  which 
  were 
  all 
  originally 
  assigned 
  

   to 
  Dendroides, 
  Latr., 
  may 
  be 
  tabulated 
  as 
  follows 
  : 
  — 
  

  

  1. 
  (4j 
  Second 
  joint 
  of 
  autennge 
  longer 
  than 
  broad 
  ; 
  

   joints 
  4-10 
  of 
  c? 
  scarcely 
  broader 
  towards 
  

   apex 
  ; 
  colour 
  blackish 
  piceous, 
  with 
  pur- 
  

   plish-red 
  elytra.
