  nov. 
  

  

  BY 
  R. 
  C. 
  L. 
  PERKINS, 
  

  

  Reddish 
  brown, 
  the 
  prothorax 
  above 
  being 
  darker 
  than 
  the 
  elytra 
  or 
  

   legs, 
  clothed 
  with 
  sparse 
  pale 
  pubescence. 
  Furcate 
  pubescent 
  lines 
  of 
  

   the 
  elytra 
  slender, 
  pale 
  yellowish, 
  distinct. 
  Antennae 
  clear 
  testaceous. 
  

   Behind 
  the 
  antennae 
  the 
  head 
  has 
  very 
  large 
  and 
  shallow, 
  but 
  not 
  dense, 
  

   punctures; 
  the 
  pronotum 
  above 
  appears 
  bare 
  on 
  the 
  large 
  subovate 
  dark 
  

   area, 
  already 
  mentioned, 
  though 
  in 
  reality 
  it 
  bears 
  extremely 
  short 
  black 
  

   hairs; 
  at 
  the 
  sides 
  it 
  has 
  a 
  pale 
  pubescence 
  and 
  is 
  finely 
  punctate, 
  the 
  

   punctures 
  becoming 
  much 
  less 
  numerous 
  towards 
  the 
  sternum, 
  with 
  the 
  

   surface 
  smooth 
  and 
  shining. 
  The 
  elytra 
  are 
  densely 
  and 
  rugosely 
  pun- 
  

   ctate 
  throughout. 
  Middle 
  and 
  posterior 
  femora 
  with 
  conspicuous 
  black 
  

   hairs 
  apically, 
  generally 
  more 
  or 
  less 
  mixed 
  with 
  some 
  white 
  ones 
  at 
  the 
  

   tip; 
  hind 
  femora 
  with 
  dense 
  hairs 
  throughout, 
  those 
  at 
  the 
  extreme 
  base 
  

   white, 
  the 
  rest 
  black; 
  hind 
  tarsi 
  with 
  whitish 
  hairs. 
  

  

  Hab. 
  Oahu, 
  on 
  Pipturtis; 
  not 
  rare, 
  and 
  easily 
  bred, 
  but 
  it 
  re- 
  

   quires 
  good 
  eyesight 
  to 
  collect 
  a 
  series 
  in 
  the 
  field, 
  as 
  it 
  closely 
  

   resembles 
  the 
  surface 
  on 
  which 
  it 
  rests, 
  and 
  is 
  as 
  a 
  rule 
  sluggish.

  koebelei, 
  an 
  

   autochthonous 
  species 
  of 
  beetle 
  hither- 
  

   to 
  undescribed. 
  On 
  request, 
  Dr. 
  

   Perkins 
  has 
  kindly
