 plumbeous, the sclerites underneath the wing yellowish; wings with Sc a little 

 longer, sometimes extending to about half the length of Rs.

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 infumed 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 rostrum of numenius is much longer than in plum- 

 hei pleura. 



Geranomyia townsendi sp. n. 



Rostrum very long and slender, in the male almost as long as the body; 

 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, S.S to 9 mm.; 

 rostrum, 7.1 to 7.4 mm. 



Rostrum very long and slender, black, a little paler at the tij). Fal{ii 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 i)ule gray silver^' mark, 

 a dark brown patch on the vertex on cither 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
