Anopheles \A*noph"e*les\ ([.a]*n[o^]f"[-e]*l[=e]z), n. [NL.,
         fr.
   Gr. 'anwfelh`s useless, hurtful.] (Zool.)
   A
         genus of mosquitoes which are secondary hosts of the
  
         malaria parasites, and whose bite is the usual, if not the

           only, means of infecting human beings with malaria.
         Several
   species are found in the United States. They may
         be
   distinguished from the ordinary mosquitoes of the
         genus
   Culex by the
         long slender palpi, nearly equaling the beak
   in length,
         while those of the female Culex are very short.
  
         They also assume different positions when resting, Culex
   usually holding the
         body parallel to the surface on which it
   rests and
         keeping the head and beak bent at an angle, while
  
         Anopheles holds the
         body at an angle with the surface
         and
   the head and beak in line with it. Unless they
         become
   themselves infected by previously biting a
         subject affected
   with malaria, the insects cannot
         transmit the disease.
