  narrower, 
  one-third 
  less 
  so 
  than 
  in 
  Dicerca, 
  but 
  not 
  reaching 
  beyond 
  the 
  

   distal 
  end 
  of 
  the 
  2d 
  palpal 
  joint. 
  The 
  two 
  palpal 
  joints 
  are 
  a 
  little 
  

   longer 
  and 
  slenderer 
  than 
  in 
  Dicerca; 
  1st 
  joint 
  much 
  narrower 
  than 
  in 
  

   Dicerca, 
  the 
  2d 
  joint 
  conical 
  at 
  tip, 
  and 
  as 
  long 
  as 
  the 
  1st 
  is 
  thick.

  This 
  is 
  not 
  an 
  Ancylocheira 
  nor 
  Anthaxia, 
  according 
  to 
  Perris^ 
  figures, 
  

   but 
  is 
  related 
  to 
  Melanophila. 
  Unlike 
  the 
  larvse 
  of 
  this 
  genus, 
  however, 
  

   it 
  has 
  no 
  ^'unguiform 
  spine," 
  but 
  three 
  equal 
  radiating 
  spines 
  on 
  the 
  tip 
  

   of 
  the 
  lobe, 
  while 
  the 
  ligula 
  is 
  entire. 
  It 
  cannot 
  be 
  a 
  Buprestis 
  (B. 
  macu- 
  

   Uventris) 
  as 
  it 
  dift'ers 
  from 
  Buprestis 
  (Ancylocheira) 
  as 
  described 
  by 
  

   Perris, 
  in 
  the 
  entire 
  labium 
  and 
  the 
  much 
  longer 
  labrum 
  as 
  well 
  as 
  the 
  

   much 
  shorter 
  lobe 
  of 
  the 
  maxilla 
  and 
  in 
  the 
  marking 
  of 
  the 
  prothorax.

  on

  In 
  addition 
  to 
  the 
  description 
  given 
  on 
  p. 
  108 
  of 
  Bulletin 
  7, 
  the 
  fol- 
  

   lowing 
  characters 
  may 
  be 
  given. 
  The 
  mouth-parts 
  are 
  as 
  described 
  in 
  

   Chrysohothris 
  femorata, 
  and 
  a 
  drawing 
  could 
  not 
  well 
  show 
  the 
  generic 
  

   or 
  specific 
  differences 
  between 
  Chrysohothris 
  femorata 
  and 
  D. 
  divaricata 
  

   as 
  regards 
  these 
  parts. 
  They 
  are 
  as 
  described 
  in 
  G. 
  femorata; 
  the 
  labium 
  

   is 
  the 
  same, 
  but 
  with 
  the 
  front 
  edge 
  perhaps 
  a 
  little 
  less 
  full 
  and 
  rounded. 
  

   The 
  maxillae 
  are 
  perhaps 
  a 
  little 
  fuller. 
  Antennae 
  the 
  same, 
  the 
  3d 
  

   joint 
  minute 
  and 
  rounded. 
  On 
  the 
  whole, 
  the 
  antennae 
  and 
  maxillae 
  are 
  

   a 
  little 
  stouter, 
  and 
  slightly 
  more 
  developed 
  than 
  in 
  (7. 
  femorata. 
  The 
  

   labrum 
  is, 
  however, 
  less 
  full 
  and 
  rounded 
  on 
  the 
  front 
  edge. 
  On 
  the 
  

   mesothoracic 
  segment 
  is 
  a 
  transverse 
  narrow 
  chitinous 
  area, 
  while 
  that 
  

   on 
  the 
  metathoracic 
  segment 
  is 
  of 
  a 
  double 
  lunoid 
  shape. 
  The 
  1st 
  

   abdominal 
  segment 
  has 
  a 
  short, 
  narrow 
  dorsal 
  area, 
  shorter 
  than 
  the 
  

   one 
  on 
  the 
  preceding 
  segment. 
  The 
  lateral 
  linear 
  crescent-shaped 
  im- 
  

   pressed 
  lines 
  are 
  well 
  marked. 
  

  

  This 
  larva 
  differs 
  from 
  that 
  of 
  Chrysohothris 
  femorata 
  in 
  being 
  con- 
  

   siderably 
  larger, 
  the 
  abdominal 
  segments 
  being 
  thicker 
  in 
  proportion 
  

   to 
  the 
  prothorax, 
  and 
  also 
  in 
  the 
  style 
  of 
  sculpturing 
  on 
  the 
  prothorax. 
  

   The 
  apex 
  of 
  the 
  V 
  is 
  surrounded 
  by 
  a 
  square, 
  deeper-colored 
  area; 
  the 
  

   disk 
  on 
  the 
  under 
  side 
  is 
  divided 
  by 
  a 
  double 
  line, 
  which 
  widens 
  sud- 
  

   denly 
  in 
  front 
  into 
  halves.

  Tjie 
  accompanying 
  figure 
  represents 
  a 
  Buprestid 
  larva, 
  mentioned 
  in 
  

   Bulletin 
  7, 
  p.

  (No.

  It 
  is 
  20™"^ 
  in 
  length, 
  and 
  Dr. 
  Gissler^s 
  figures 
  so 
  well 
  represent 
  the 
  

   larva, 
  that 
  a 
  longer 
  description 
  will 
  not 
  at 
  this 
  time 
  be 
  needed.
