OF WASHINGTON. 255 
the rest of the legs pale yellowish, with a dot at the extremity of the 
femora on the upper side ; the extremities of the tibiae, especially the hind 
pair, and the lower portion of each joint of all the tarsi very dusky- The 
basal joint of the hind tarsi, which is as long as the three following 
joints put together, is furnished on the outer edge with a brush of fine, 
short hairs. This species occurs throughout the Atlantic States. 
Trichopoda radiata, Loew. The species of the genus Trichopoda are 
flower-flies. They belong to the first section (Phasina) of the Tachinidce. 
The species vary from rather small up to large and strikingly appearing 
flies, and are characterized, at least in all the specimens that I have seen, 
by having the upper edge of the hind tibiae ciliate. Only one specimen 
of the present species was collected, this one being taken August 19, on 
flowers ofJmw?y7*Dy Mr. Marlatt. The pulvilli are remarkably developed, 
elongate, and of a beautiful light honey-yellow color, each pulvillus bifid 
and apparently consisting of a prong and sheath joined at the base, giving 
the feet the appearance of having each four anthers, like those of certain 
grasses, sticking to them. The empodia are bristle-like and of nearly the 
same color. It is readily recognized by Loew's description, and is there 
recorded from the District of Columbia. 
Trichopoda hirtipes, Fab. Two specimens, probably this species, were 
taken August 19, on flowers of mint and golden rod. They are very near 
to T. lanipes Fab., differing only in having the basal half or more of the 
abdomen and the bases of the femora rufous, while in lanipes the legs 
and abdomen are entirely black. This species bears the locality of 
Carolina in the O. S. list. 
Trichopoda ciliata, Fab. This is a smaller species, and the specimen 
which I have doubtfully referred here, the only one mentioned in these 
notes not from the Virginia side, was taken by Mr. Howard, at Clopper's 
Station, Maryland, August 4, on flowers of boneset. This species is 
recorded by Macquart from Carolina, and by Fabricius and Wiedemann 
from South America. 
Trichopoda sp. Another specimen, very much resembling the pre- 
ceding, and of nearly the same size, but with the abdomen almost entirely 
light orange, while that of the preceding is well tipped with black, was 
taken August 19, on flowers of mint. 
Palloptera superba, Loew. This species belongs to the Lonchceidcz, a 
small family comprising in North America only the two genera, Pallop- 
tera and Lonchcea. It is a very pale-colored fly, with the wings prettily 
marked with smoky-black, and is found only in the shade of the woods, 
on the under side of leaves of various trees. I took four or five specimens 
from August n to 19, on under-side of lower leaves of oak and dogwood, 
about as high up from the ground as I could reach. They are not shy, 
but when disturbed are very quick in their movements. The species was 
described by Loew from specimens taken in Pennsylvania, and has been 
recorded for this vicinity by Glover. The only other N. A. representatives 
of this genus are two smaller species described 1y Loew from Sitka.
