  distinctly 
  white 
  pollinose, 
  

   leaving 
  a 
  black 
  central 
  stripe 
  and 
  posterior 
  triangular 
  dilatations 
  on 
  

   each

   hair-like 
  bristle; 
  antero-ventral 
  surface 
  with 
  a 
  row 
  of 
  about 
  20-22 
  

   bristles 
  which 
  begin 
  at 
  base 
  rather 
  weak 
  and 
  gradually 
  become 
  longer 
  

   and 
  rather 
  wider 
  spaced 
  to 
  middle, 
  then 
  decrease 
  gradually 
  in 
  size 
  

   and 
  become 
  closer 
  placed 
  on 
  the

  nkrrowed 
  apical 
  third; 
  the 
  

   postero-ventral 
  row 
  is 
  of 
  similar 
  nature, 
  but 
  the 
  basal 
  3-4 
  are

  those 
  on

  base 
  of 
  antero-ventral 
  surface; 
  

   posterior 
  surface 
  with 
  a 
  row

  which 
  are 
  curled

   hair-like 
  to 
  beyond 
  the

  two 
  very 
  

   strong 
  bristles 
  on 
  apical 
  third,

  b}^ 
  two 
  weaker 
  bristles, 
  which 
  

   are 
  much 
  closer 
  placed;

  One 
  male. 
  White 
  Mountains, 
  New 
  Hampshire 
  (Morrison). 
  

  

  This 
  species 
  is 
  allied 
  to 
  carhonella 
  Stein, 
  but 
  that 
  species 
  has 
  the 
  

   calyptrse 
  equal 
  in 
  size 
  or 
  very 
  slightly 
  unequal, 
  and 
  the 
  halteres 
  are 
  

   black. 
  It 
  also 
  comes 
  very 
  close 
  to 
  atra 
  Stein, 
  and 
  nigra 
  Malloch. 
  

   From 
  the 
  first 
  named 
  it 
  differs 
  in 
  the 
  bristling 
  of 
  the 
  hind 
  femora, 
  

   and 
  from 
  the 
  latter 
  in 
  the 
  absence 
  of 
  the 
  additional 
  bristle 
  above 
  the 
  

   normal 
  one 
  present 
  on 
  mid 
  tibia, 
  as 
  well 
  as 
  in 
  some 
  minor 
  particulars. 
  

  

  Named 
  after 
  H. 
  K. 
  Morrison, 
  who 
  collected 
  the 
  specimen.
