  GEOGRAPHICAL 
  DISTRIBUTION 
  OF 
  THE 
  SPECIES 
  AND 
  SUBSPECIES. 
  

  

  Lasiopyga 
  is 
  strictly 
  an 
  African 
  genus 
  and 
  its 
  members 
  are 
  dis- 
  

   persed 
  over 
  the 
  entire 
  continent, 
  save 
  the 
  extreme 
  northern 
  part 
  lying 
  

   along 
  the 
  Mediterranean 
  Sea. 
  They 
  are 
  also 
  found 
  on 
  the 
  large 
  island 
  

   of 
  Fernando 
  Po, 
  but 
  not 
  on 
  Madagascar. 
  Of 
  the 
  known 
  species 
  about 
  

   thirty-nine 
  are 
  East 
  African, 
  thirty-four 
  West 
  African, 
  two 
  South 
  

   African, 
  both 
  ranging 
  northward 
  on 
  the 
  east 
  and 
  west 
  coasts, 
  and 
  the 
  

   dispersion 
  of 
  six 
  remaining 
  species 
  is 
  quite 
  unknown. 
  It 
  will 
  thus 
  be 
  

   perceived 
  that 
  there 
  are 
  something 
  like 
  eighty 
  species 
  and 
  races 
  at 
  

   present 
  recognized 
  and 
  doubtless 
  many 
  more 
  are 
  yet 
  to 
  be 
  discovered, 
  

   as 
  the 
  interior 
  of 
  Africa 
  is 
  better 
  known. 
  Beginning 
  in 
  the 
  north- 
  

   eastern

   Nile, 
  L. 
  neglectus 
  Schlegel, 
  its 
  range 
  unknown, 
  probably 
  somewhat 
  

   restricted 
  as 
  the 
  type 
  is 
  still 
  unique 
  although 
  the 
  species 
  was 
  described 
  

   over 
  thirty 
  years 
  ago.
