  of 
  its 
  length 
  ; 
  the 
  transfer 
  apparatus 
  is 
  in 
  the 
  form 
  of 
  a 
  small 
  bent 
  chitinous 
  rod 
  ; 
  

   the 
  struts 
  of 
  the 
  median 
  lobe 
  are 
  comparatively 
  short 
  and 
  unusually 
  slender 
  and 
  

   delicate, 
  breaking 
  off 
  very 
  readily 
  in 
  dissection. 
  The 
  vagina 
  of 
  the 
  female 
  is 
  lightly 
  

   and 
  irregularly 
  chitinised; 
  the 
  palps 
  are 
  conspicuous 
  (0-26 
  mm. 
  long), 
  and 
  each 
  

   bears 
  one 
  or 
  two 
  short 
  setae 
  and 
  two 
  that 
  are 
  about 
  three-fourths 
  the 
  length 
  of 
  the 
  

   palp 
  ; 
  below 
  each 
  palp 
  is 
  a 
  prominence 
  bearing 
  a 
  seta 
  nearly 
  half 
  as 
  long 
  again 
  as 
  

   the 
  palp, 
  and 
  two 
  very 
  short 
  ones. 
  The 
  bursa 
  copulatrix 
  is 
  about 
  as 
  long 
  as 
  the 
  

   vagina 
  and 
  twice 
  as 
  long 
  as 
  broad, 
  very 
  lightly 
  and 
  indefinitely 
  chitinised 
  in 
  the 
  

   anterior 
  (proximal) 
  half, 
  and 
  with 
  irregular 
  darker 
  chitinous 
  stripes 
  in 
  the 
  

   posterior 
  third. 
  

  

  Subfamily 
  Liparixae.

  Mr. 
  G. 
  N. 
  Wolcott 
  states 
  that 
  specimens 
  of 
  this 
  species 
  were 
  found 
  in 
  a 
  rotten 
  

   stump 
  of 
  a 
  castor-oil 
  plant 
  at 
  Rio 
  Piedras, 
  Porto 
  Rico. 
  The 
  attack 
  was 
  probablv 
  

   a 
  secondary 
  one, 
  but 
  as 
  very 
  little 
  is 
  known 
  as 
  to 
  the 
  habits 
  of 
  the 
  species 
  of 
  this 
  

   genus, 
  it 
  is 
  perhaps 
  worth 
  recording. 
  

  

  The 
  Cuban 
  specimens 
  examined 
  differ 
  only 
  in 
  having 
  a 
  trace 
  of 
  a 
  median 
  costa 
  

   on 
  the 
  pronotum, 
  which 
  is 
  not 
  likely 
  to 
  be 
  a 
  reliable 
  distinction.

  Integument 
  black, 
  thinly 
  clothed 
  above 
  and 
  below 
  with 
  minute 
  hair-like 
  

   brownish 
  grey 
  scales, 
  with 
  the 
  following 
  markings 
  of 
  much 
  larger 
  narrow 
  white 
  

   scales 
  : 
  a 
  narrow, 
  rather 
  irregular 
  stripe 
  on 
  each 
  side 
  of 
  the 
  prothorax, 
  and 
  a 
  similar 
  

   short 
  obliquely-transverse 
  lateral 
  band 
  outside 
  each 
  stripe 
  and 
  uniting 
  with 
  it 
  a 
  

   little 
  behind 
  the 
  middle 
  ; 
  the 
  elytra 
  with 
  three 
  similar 
  narrow 
  transverse 
  bands 
  

   (often 
  more 
  or 
  less 
  interrupted), 
  the 
  first 
  near 
  the 
  base, 
  the 
  second 
  at 
  the 
  middle, 
  

   and 
  the 
  third 
  about 
  half-way 
  between 
  the 
  middle 
  and 
  the 
  apex 
  ; 
  the 
  first 
  runs 
  

   obliquely 
  from 
  the 
  scutellum 
  to 
  the 
  lateral 
  margin 
  a 
  little 
  in 
  front 
  of 
  the 
  hind 
  coxa, 
  

   and 
  at 
  its 
  inner 
  end 
  continues 
  along 
  the 
  side 
  of 
  the 
  scutellum 
  and 
  for 
  a 
  short 
  distance 
  

   along 
  the 
  suture 
  ; 
  the 
  second 
  extends 
  from 
  the 
  suture 
  to 
  stria 
  8, 
  curving 
  slightly 
  

   forwards 
  at 
  the 
  side 
  and 
  almost, 
  or 
  quite, 
  uniting 
  with 
  the 
  first 
  ; 
  the 
  third 
  extends 
  

   to 
  stria 
  8 
  or 
  9 
  ; 
  between 
  the 
  second 
  and 
  third 
  there 
  are 
  usually 
  irregular 
  white 
  

   marks 
  along 
  the 
  suture.

   far 
  from
