into the southern limits of the territory here considered. This is a curious 
fly which is common all over the South, where in some sections it is called 
“weaver.” The flies of this species have a remarkable dance over a 
vertical height of several feet, and have been aptly termed ‘the kings 
of the dancing crane-flies.”” The larval life is spent in decaying wood.

Dolichopeza americana is a curious fly usually found beneath bridges 
and culverts, or in similar darkened situations. The adults hang sus- 
pended from the roof by the anterior two pairs of feet, the wings being 
spread wide apart and the long, white-tipped hind legs dangling con- 
spicuously. The dark color of the body and the pure white tarsi easily 
serve to distinguish the species from the forms of Oropeza that may be 
found with it. The wing venation is shown in Plate XLIII, 187.
