1912] New Western Tipula 51 
would be in a group lower than any he studied, a group cor- 
responding to the simplest of the brevipalpi where the pleura 
and sterna are entirely separated. 
Tipula albimacula n. sp. 
Brownish yellow; head brownish yellow with a darker stripe above; 
first segment of palpi yellowish others brownish, last segment darker; 
antenne yellowish toward the base, growing darker toward the tip, 
last four or five segments brown; metanotum brown with three broad, 
darker brown stripes; pleura yellowish, pruinose, with a rather broad, 
brown stripe extending from above the base of the first coxee to the base 
of the wings; scutellum brown with a median lighter line; metanotum 
yellowish with a very narrow median brown line; legs yellowish, tarsi 
and tips of femora and tibia darker; abdomen yellowish, spotted with 
brownish, with dorsal and lateral brown stripes; first, sixth, seventh and 
eighth terga brownish; ninth tergite tumid, posterior margin with a 
broad crescent-shaped incision in the middle of which is a small semi- 
circular incision; ninth sternite similar to the preceding sternites, pos- 
terior margin bearing a pair of leaf-like appendages which are attached 
near the middle of their long sides, the margins of the opposing faces 
shightly curled in, thus forming an incomplete tube; pleural suture 
extending to the anterior margin of the segment so that the pleural 
sclerites are completely separated from the others; upper appendages. 
broad, rounded, margins somewhat more chitinized; lower appendages 
long, rather broad, somewhat twisted, ending in an upper rather broad, 
blunt arm and a lower narrow, curved, sharp-pointed claw; wings with 
a brownish tinge with several lighter and darker spots; an irregular 
broken V-shaped, whitish band beginning in front of the stigma and 
ending close to the tip of the sixth vein; a rather large irregular whitish 
spot on the margin of the axillary cell and other smaller whitish spots 
in all of the cells in the apical portion of the wing; the whitish spots in 
the margins of the posterior cells are bordered on each side by brownish 
spots. Length 20 mm., wing 22 mm. 
Habitat; Arizona. 1 male: 
See the note in regard to the hypopygium of T. rupicola.

above and brownish lines back of the eyes; rostrum grayish brown, 
darker laterally; palpi dark brown; antennze yellowish, base of each

ish stripes each of which is margined by darker brown; median stripes 
divided by a narrow brown line, lower margin of metanotum bordered 
by a brown line; pleura grayish pruinose with two median brown spots 
and a brown stripe which begins on the prothorax and ends just beyond 
the mesopleural suture; scutellum and metanotum grayish, each with 
a median brown line; a brown spot above the base of the halteres; 
halteres yellowish, knobs brown; legs yellowish, tarsi and tips of femora
