MYIASIS  IN  MAN  PRODUCED  BY  THE  LARVAE  OF 
CHRYSOMYIA  lC03fPS0J/YIA}  MACELLARIA 
Dr.  J.  A.  Allwood  of  Kingston  very  kindly  presented  to  the  School 
three  immature  larvae  of  this  horrid  pest  which  he  extracted  from 
the  ear  of  a  Syrian,  December  26th,  1909. 
Though  immature  they  are  undoubtedly  referable  to  this  species, 
and  there  can  be  little  doubt  that  the  patient  had  become  infested 
during  his  short  stay  in  the  Island.  At  Constant  Spring  and  also  in 
other  parts  of  the  parish  of  St.  Andrews  this  insect  is  one  of  the 
commonest  of  the  ‘  blow  flies,’  and  the  foetid  carcase  of  a  bird  or 
mammal,  placed  in  the  sun,  forms  an  attractive  bait  for  this  very 
handsome  thoug'h  much  dreaded  Muscid.  They  are  extremely  active 
in  their  habits ;  but  though  repeatedly  disturbed  by  the  sweep  of  the 
fly-net  they  would  return  again  and  again  to  the  same  tempting  bait.
