  A 
  relatively 
  small 
  species, 
  the 
  distinguishing 
  features 
  of 
  which 
  are 
  the 
  densely 
  

   packed 
  group 
  of 
  long 
  stiff 
  bristles 
  at 
  the 
  end 
  of 
  the 
  inferior 
  claspers 
  and 
  the 
  two 
  pairs 
  

   of 
  widely 
  separated 
  spines 
  on 
  the 
  superior 
  claspers.

  ingrami, 
  sp.n.,

  ; 
  a, 
  genital 
  armature, 
  X 
  150 
  ; 
  

   by 
  distal 
  portion 
  of 
  inferior 
  clasper, 
  x 
  225. 
  

  

  Antennae 
  composed 
  of 
  long 
  slender 
  segments 
  similar 
  to 
  those 
  of 
  P. 
  simillimus, 
  but 
  

   the 
  third 
  segment 
  is 
  relatively 
  shorter 
  and 
  barely 
  reaches 
  to 
  the 
  tip 
  of 
  the 
  proboscis. 
  

   Palpi 
  relatively 
  stout, 
  2nd 
  segment 
  about 
  half 
  the 
  length 
  of 
  the 
  fourth. 
  Wings 
  

   narrowly 
  lanceolate 
  ; 
  tip 
  of 
  1st 
  longitudinal 
  vein 
  overlapping 
  the 
  anterior 
  branch 
  of 
  

   the 
  second 
  vein 
  by 
  a 
  little 
  more 
  than 
  one-third 
  its 
  total 
  length. 
  Legs 
  densely 
  clothed 
  

   with 
  narrowly 
  lanceolate 
  scales 
  ; 
  ungues 
  simple 
  and 
  near 
  them, 
  on 
  the 
  tarsus, 
  three 
  

   pairs 
  of 
  spines, 
  the 
  ventral 
  pair 
  minute 
  ; 
  the 
  subventral 
  pair 
  about 
  half 
  the 
  length 
  

   of 
  the 
  lateral 
  ones. 
  External 
  genital 
  armature 
  (fig. 
  1, 
  a) 
  relatively 
  small 
  compared 
  

   with 
  the 
  width 
  of 
  the 
  abdomen 
  ; 
  terminal 
  segment 
  of 
  the 
  superior 
  claspers 
  with 
  two 
  

   pairs 
  of 
  widely 
  separated 
  spathuliform 
  spines 
  ; 
  inferior 
  claspers 
  (fig. 
  1, 
  b) 
  with 
  a 
  

   densely 
  packed 
  group 
  of 
  long 
  stiff 
  bristles 
  ; 
  there 
  are 
  5 
  of 
  these 
  on 
  one 
  of 
  the 
  appen- 
  

   dages 
  and 
  7 
  or 
  8 
  on 
  the 
  other, 
  possibly 
  one 
  or 
  more 
  may 
  have 
  been 
  broken 
  away 
  from 
  

   the 
  former 
  in 
  preparing 
  the 
  specimen 
  for 
  microscopical 
  examination. 
  

  

  I 
  cannot 
  unfortunately 
  give 
  any 
  details 
  regarding 
  the 
  general 
  arrangement 
  of 
  the 
  

   hairs 
  on 
  the 
  body, 
  as 
  the 
  specimens 
  were 
  mounted 
  in 
  Canada 
  balsam 
  before 
  they 
  were 
  

   seen 
  to 
  differ 
  in 
  any 
  marked 
  degree 
  from 
  P. 
  minutus 
  var. 
  africanus, 
  Newst., 
  with 
  which 
  

   they 
  were 
  associated. 
  I 
  have 
  pleasure 
  in 
  dedicating 
  this 
  very 
  distinct 
  species 
  to 
  

   its 
  discoverer.
