plumose, and forked at the extremity ; wings white, about 

 a line in length. The Midge very closely resembles the 

 true Gnat, but differs in wanting the long proboscis. The 

 antennae are ornamented with whorls of hair, which, in the

Generic Distinctions. Antenna, second joint very short, terminal 

 one long ; palpi very visible ; proboscis very long ; body short, thick,

 is inappropriate, as it is larger than B. major. 



BOMBYLIUS MINOR is much smaller than either of the 

 preceding species ; the wings are quite clear. 



These insects are very active, flying with great rapidity ; 

 they hover over flowers without settling on them, but extract
