 Genus LXV. MUSCA. 



GENERIC CHARACTER. 



Antenna short. Mouth with a short fleshy 

 proboscis or trunk, which is retractile, bila- 

 biate, and channeled. Palpi two, very short. 



General Observations, 



Linnaeus has divided the Muscae into the 

 following families, founded on the form of their 

 antennae : 



1. Filatce. With simple antennae, or without 



any lateral hair, or feather. 



2. Armatte. In which the antennae have a 



lateral hair, or plume. These are sub- 

 divided into 



Tomentosce or Pilosce. 



The former have the body very slightly 

 downy, and the antennae are either 



Plumatce, feathered, or 



Setarice, with a simple lateral bristle.
