on either side of the inidtUe stripe; the pronotum shows a dark brown dorsal 
line continuous with the median praescutal vitta and a short dark brown lateral 
stripe; praescutum with the grountl color more grayish, the lateral stripes 
broadened toward the caudal end; pleura with the dorsal pleurites grayish 
plumbeous, the sclerites underneath the wing yellowish; wings with Sc a little 
longer, sometimes extending to about half the length of /?s.

Related to G. insignis Loew'^ which has the antennal flagellum 
light brown, not black; stripes on the praescutum narrow, the 
middle one not broadened out in front; pleura yellow, not gray- 
ish; the wings more uniformly yellowish, not infumecl with darker, 
the brown markings neither so dark nor so extensive. With G. 
numenius Alexander^'' it agrees in the color of the antennae and 
the head but the antennae are shorter, the individual flagellar 
segments being much more rounded; the thorax is plumbeous, 
not yellowish as in numenius, and the wing-pattern is entirely 
different; the rostrinn of numenius is much longer than in plum- 
beipleura. 
Geranomyia townsendi sp. n. 
Rostrum very long and slender, in the male almost as long as the liody; 
head silvery and black; thoracic coloration reddish with indistinct narrow 
stripes; femora with a brown subapical ring; wings light gray with large rounded 
brown clouds. 
Male. — Length, excluding the rostrum, 7.3 to 8.2 mm.; wing, 8.8 to 9 mm.; 
rostrum, 7.1 to 7.4 mm. 
Rostrum very long and slender, black, a little paler at the tip. Palpi two- 
segmented, black. Antennae rather long, the flagellar segments elongated, 
the segments dark brown with a gray bloom, the extreme tips of each segment 
indistinctly reddish. Head with a narrow median pale gray silvery mark, 
a dark Ijrown patch on the vertex on either side of this pale mark; vertex ad- 
joining the eyes and the occiput gray. 
Thoracic dorsum reddish brown with narrow indistinct brown stripes as 
follows: a dark brown median stripe extending the length of the praescutum, 
more or less indistinct lateral stripes behind the pseudosutural foveae; scutum
