FOSSORES. Lat. 
Never more than two kinds of individuals, and both have 
wings ;—the superior ones not longitudinally folded. The 
tongue never lanceolate or filiform, the feet never adapted 
to collect pollen; the posterior tibiz never either very 
hirsute like a brush, or hollowed like a basket; the first 
joint of the tarsi attached to them is never much wider than 
the subsequent ones. The other parts of the body never 
present hairs suited to gather pollen.

1. The latter have their feet short and the antenne thick, with 
their joints very close and short.
