  Revision 
  of 
  

  

  Tlie 
  species 
  may 
  be 
  separated 
  as 
  follows 
  : 
  — 
  

  

  1.

  Head

  (3) 
  Underside 
  and 
  limbs 
  testaceous 
  ; 
  elytra 
  sub- 
  

  

  opaque 
  ; 
  frontal 
  excavation 
  of 
  J 
  almost 
  

   closed 
  by 
  hood-liife 
  projection 
  of 
  the 
  

   vertex.

  (2) 
  Underside 
  and 
  limbs 
  in 
  greater 
  part 
  piceous 
  ; 
  

  

  elytra 
  more 
  nitid 
  ; 
  eyes 
  more 
  approxi- 
  

   mate 
  ; 
  frontal 
  excavation 
  of 
  ^ 
  bi- 
  

   foveate, 
  widely 
  open 
  ; 
  vertex 
  only 
  

   slightly 
  prominent 
  femoralis, 
  Lee. 
  

  

  4. 
  (1) 
  Head 
  black 
  *califvrnica, 
  Horn. 
  

  

  Hemidendroides, 
  Ferr. 
  

  

  This 
  was 
  proposed 
  as 
  a 
  subgenus 
  of 
  Dendroides 
  , 
  although 
  

   its 
  athuity 
  with 
  Pyruchroa, 
  as 
  evidenced 
  by 
  the 
  structure 
  of 
  

   the 
  head 
  and 
  antennae, 
  is 
  closer 
  than 
  with 
  the 
  Aiuericau 
  

   genus. 
  From 
  the 
  description 
  it 
  is 
  probable 
  that 
  P. 
  davidis, 
  

   Fairm., 
  should 
  be 
  placed 
  here. 
  

  

  The 
  species 
  are 
  as 
  follows 
  : 
  —

  Elytra 
  unicolorous, 
  testaceous

  ledereri,

  (2) 
  Head 
  and 
  thorax 
  concolorous 
  with 
  elytra 
  .... 
  ijeyroni,

  4. 
  (1) 
  Elytra 
  black, 
  with 
  suture 
  and 
  apex 
  red 
  ; 
  head 
  

  

  and 
  thorax 
  dark 
  red 
  *davidis, 
  Fairm. 
  

  

  EUPYROCHROA, 
  gCU. 
  UOV. 
  

  

  Differs 
  from 
  Pi/rochroa 
  in 
  its 
  large 
  size 
  and 
  in 
  the 
  conical 
  

   genae, 
  which 
  project 
  beyond 
  the 
  eyes. 
  The 
  sides 
  of 
  the 
  

   prothorax 
  also 
  project 
  strongly 
  just 
  before 
  the 
  base 
  ; 
  the 
  

   elytra 
  are 
  more 
  explanate 
  behind 
  and 
  more 
  distinctly 
  

   tricostate. 
  

  

  There 
  are 
  only 
  two 
  described 
  species^ 
  which 
  may 
  be 
  

   separated 
  as 
  follows 
  : 
  — 
  

  

  Head 
  and 
  thorax 
  shining 
  black 
  ; 
  elytra 
  bright 
  red. 
  

  

  (Pi. 
  XII. 
  tig. 
  6.) 
  insiffnita, 
  Fairm. 
  

  

  Head 
  black 
  ; 
  thorax 
  and 
  elytra 
  dull 
  red, 
  the 
  former 
  

  

  with 
  black 
  spot 
  on 
  disc 
  and 
  black 
  on 
  sides 
  .... 
  limhaticollis, 
  Pic. 
  

  

  Of 
  these, 
  the 
  latter 
  was 
  described 
  as 
  a 
  variety 
  of 
  the 
  

   former; 
  but 
  M. 
  Pic 
  now 
  agrees 
  with 
  me 
  that 
  it 
  is 
  probably 
  

   a 
  good 
  species. 
  

  

  * 
  Known 
  to 
  me 
  only 
  from 
  description.
