  This 
  seems 
  to 
  be 
  principally 
  an 
  Oahuan 
  species. 
  I 
  have 
  now 
  

   only 
  one 
  Mauian 
  example 
  before 
  me, 
  which 
  differs 
  by 
  the 
  unicol- 
  

   orous 
  pale 
  red-brown 
  tegmina, 
  not 
  chequered 
  laterally. 
  For 
  the 
  

   present, 
  it 
  may 
  be 
  termed 
  var. 
  mauiensis. 
  The 
  smaller 
  dimen- 
  

   sions 
  given 
  for 
  njida 
  belong 
  to 
  the 
  next 
  species.

  The 
  genital 
  characters 
  separating 
  this 
  from 
  nuda 
  seem 
  very 
  

   slight, 
  but 
  some 
  examples 
  from 
  Hawaii 
  are 
  distinctly 
  smaller 
  and 
  

   darker, 
  and 
  seem 
  to 
  constitute 
  a 
  good 
  species,

  In 
  the 
  "Fauna 
  Hawaiiensis" 
  I 
  described 
  the 
  i 
  labium 
  

   as 
  reaching 
  to, 
  or 
  slightly 
  beyond, 
  the 
  hind 
  coxae, 
  the 
  9 
  labium 
  

   as 
  reaching 
  to 
  the 
  base 
  of 
  the 
  4th 
  sternite. 
  This 
  does 
  not 
  at 
  all 
  

   characterize 
  the 
  Oahuan 
  specimens 
  now 
  before 
  me, 
  and 
  must 
  re- 
  

   fer 
  to 
  the 
  Lanai 
  examples 
  from 
  Haalelepakai, 
  &c., 
  (which 
  may 
  

   then 
  be 
  termed 
  lanaiensis 
  sp. 
  n.). 
  In 
  contracta, 
  the 
  $ 
  labium 
  

   reaches 
  at 
  least 
  to 
  the 
  middle 
  of 
  the 
  6th 
  sternite 
  and 
  to 
  the 
  middle 
  

   of 
  the 
  ultimate 
  one 
  in 
  the 
  9 
  . 
  In 
  both 
  sexes, 
  the 
  first 
  segment 
  

   reaches 
  the 
  fore 
  coxae. 
  

  

  var. 
  picea 
  nov. 
  This 
  has 
  the 
  pronotum, 
  tegmina 
  &c., 
  fuscopi- 
  

   ceous, 
  the 
  tegmina 
  being 
  rather 
  obscurely 
  speckled 
  with 
  pallid, 
  

   which, 
  however, 
  is 
  conspicuous 
  on 
  the 
  dilated 
  part. 
  The 
  under- 
  

   side 
  is 
  almost 
  uniformly 
  piceous, 
  except 
  the 
  leg-annulations, 
  &c.

  (?

  &c.

   In 
  addition 
  to 
  the 
  "Fauna 
  Hawaiiensis" 
  series, 
  I 
  have 
  seen 
  speci- 
  

   mens 
  taken 
  by 
  Messrs. 
  Giffard, 
  Swezey, 
  Terry 
  and 
  myself. 
  

  

  M. 
  contracta 
  is 
  so 
  distinct 
  structurally 
  from 
  the 
  other 
  species, 
  

   that 
  it 
  forms 
  at 
  least 
  a 
  subgenus, 
  which 
  will 
  probably 
  be 
  raised 
  to 
  

  

  (t 
  ) 
  The 
  subfamily 
  Metrarginae 
  is, 
  so 
  far 
  as 
  is 
  known, 
  entirely 
  Ha- 
  

   waiian. 
  It 
  has 
  really 
  little 
  to 
  do 
  with 
  the 
  Cyrainae, 
  as 
  I 
  formerly 
  sup- 
  

   posed, 
  and 
  should 
  probably 
  be 
  placed 
  near 
  the 
  Oxycareninae. 
  The 
  

   spiracles 
  of 
  the 
  last 
  three 
  segments 
  open 
  on 
  to 
  the 
  sternites.
