  carbonatus, 
  from 
  a 
  specimen 
  from 
  Sicily, 
  notes 
  the 
  shape 
  of 
  the 
  upper 
  margin 
  of 
  

   the 
  third 
  antennal 
  joint. 
  

  

  According 
  to 
  Brauer 
  (loc. 
  cit.), 
  the 
  eyes 
  in 
  both 
  sexes 
  are 
  dark 
  green 
  ; 
  in 
  the 
  

   specimens 
  collected 
  near 
  Jerisheh, 
  however, 
  the 
  eyes 
  of 
  <$ 
  and 
  $ 
  in 
  life 
  were 
  

   unicolorous 
  black. 
  

  

  The 
  Museum 
  collection 
  contains 
  several 
  examples 
  (2 
  <$$, 
  3 
  $ 
  $), 
  from 
  Algeria 
  

   and 
  Tunis, 
  of 
  what 
  must, 
  at 
  any 
  rate 
  provisionally, 
  be 
  regarded 
  as 
  a 
  variety 
  or 
  

   local 
  race 
  of 
  the 
  present 
  species.* 
  This 
  western 
  form 
  is 
  distinguished 
  from 
  the 
  

   typical 
  one, 
  as 
  represented 
  by 
  Palestine 
  specimens, 
  by 
  the 
  absence 
  of 
  the 
  greyish- 
  

   white 
  hairs 
  on 
  the 
  lateral 
  margins 
  of 
  the 
  dorsum 
  of 
  the 
  thorax 
  in 
  the 
  $, 
  on 
  and 
  

   in 
  front 
  of 
  the 
  postalar 
  calli, 
  and 
  by 
  the 
  distal 
  extremity 
  of 
  the 
  expanded 
  portion 
  

   of 
  the 
  third 
  joint 
  of 
  the 
  antenna 
  being 
  distinctly 
  emarginate 
  above. 
  This 
  is 
  at 
  any 
  

   rate 
  the 
  case 
  in 
  the 
  $ 
  ; 
  in 
  the 
  two 
  $$ 
  from 
  Algeria 
  and 
  Tunis 
  the 
  third 
  joints 
  of 
  

   the 
  antennae 
  are 
  unfortunately 
  missing. 
  

  

  Brauer's 
  record 
  of 
  Tahanus 
  alexandrinus 
  from 
  Syria, 
  referred 
  to 
  above, 
  gives 
  

   no 
  more 
  precise 
  indication 
  of 
  locality, 
  but 
  Bezzi 
  (Broteria, 
  Ser. 
  Zool.,viii,1909, 
  p. 
  42) 
  

   records 
  the 
  species 
  as 
  having 
  been 
  taken 
  at 
  Ghazir 
  (about 
  15 
  miles 
  N.-E. 
  of 
  Beirut), 
  

   on 
  14th 
  June, 
  1904. 
  

  

  It 
  is 
  interesting 
  to 
  note 
  that 
  clinging 
  to 
  the 
  hair 
  clothing 
  the 
  front 
  coxae 
  of 
  one 
  

   of 
  the 
  (J 
  specimens 
  taken 
  near 
  Jerisheh 
  on 
  26th 
  April 
  1918, 
  were 
  six 
  little, 
  hexapod, 
  

   Campodea-\i\ze 
  larvae, 
  which 
  Dr. 
  Gahan 
  states 
  are 
  the 
  "triungulin" 
  stage 
  of 
  an 
  

   oil-beetle 
  (Meloe

  The
