This species appears to be a very common, early spring form, 
since it was taken in numbers May 14, 1900, flying about the flowers 
of shadbush, Amelanchier canadensis, and also about 
the flowers of wild cherry, Prunus pennsylvanica, at 
Karner, N. Y. 
Male. Length .75 mm. Antennae nearly as long as the body, 
thickly clothed with long hairs, dark brown; 14 segments, the fifth 
with a stem two-thirds the length of the subcylindric basal en- 
largement, apically a pair of oval, stemmed disks; terminal seg- 
ment obconical, sometimes fused with the preceding, the apex 
scarcely produced. Palpi; the first segment rather long, broadly 
swollen distally and with a sensory organ on the internal distal 
surface, second more slender, as long as the first, the third a little 
longer than the second, slightly stouter, the fourth one-half longer 
than the third. Thorax and abdomen dark brown or black. Wings 
hyaline, iridescent, reddish at the insertion, anterior veins brown, 
subcosta uniting with the margin at the basal half; halteres whitish 
transparent. Legs brownish yellow, tarsi light yellow, tip of pos- 
terior tibiae, anterior tarsi and the terminal segments of the middle 
and posterior tarsi variably tinged with reddish; claws slender,

terminal clasp segment slender at. base, broadly expanded distally, 
thickly setose apically. Dorsal plate broad, short, broadly rounded,
