Tipula rupicola n. sp. 
Brown; head brownish with broad, darker, dorso-median and post- 
ocular lines; rostrum darker brown; palpi very dark brown; antennz 
yellowish darker toward the tip, base of each segment beyond the third 
blackish; mesonotum tawny the three brown stripes bordered by dis- 
tinct darker brown lines, the median one divided by a rather broad, dark 
brown line; dorso-pleural membrane whitish; pleura grayish brown; an 
irregular line just below the dorso-pleural suture, and other spots, 
darker brown; scutellum and metanotum brown; halteres light yellow, 
knobs brown, tips lighter; legs yellowish brown, tarsi and tips of femora 
and tibia darker, a broad whitish ring on the femora a short distance 
from the tip; abdomen brown, darker posteriorly, lateral margin darker; 
ninth tergite somewhat tumid, posterior margin reflexed and with a 
pair of inconspicuous black edged teeth; pleural suture complete extend- 
ing to the anterior margin of the segment thus distinctly separating the 
pleura from the sternum; ninth sternite almost hidden by the eighth 
sternite; posterior margin with two broad appendages the edges of 
which are rolled in such a way that the contiguous edges of the two 
form a large projecting open tube; posterior margin of the pleura rather 
strongly chitinized, lower corner produced into a short, sharp point; 
upper pair of appendages broad, short, tips with a shallow rounded 
incision and with a fringe of black hairs; upper and posterior margin of 
second pair of appendages furnished with rather long reddish brown 
hairs the lower angle produced into a rather long spatulate projection; 
the upper posterior angle of the third pair of appendages strongly 
chitinized and bearing a few black hairs; wings rather broad and long, 
brownish with the following parts darker brown: the stigma, a spot 
over the origin of the preefurca, the base of the fourth posterior cell, 
the tips of all the veins beyond the apex of the wing, the middle of the 
posterior margin of the second basal cell, the middle of the anal cell; 
the distal portion of the second and fifth vein narrowly bordered with 
brown; a whitish spot beginning in the margin of the wing just beyond 
the stigma extends into the first posterior cell and follows it to the tip 
of the wing; another whitish spot beginning in the margin in front of 
the origin of the praefurca extends diagonally across the first basal and 
just into the second basal cell; other smaller spots in the discal, anal, 
axillary and the margins of all the posterior cells, those in the anal cell 
extending forward into the second basal cell. Length 25 mm., wing 
25 mm. 
Habitat: Oak Creek Canon, Ariz. 1 male. 
The coloring of the body and the wing markings somewhat 
resemble T, contaminata Doane, but there are several differ- 
ences the most important of which is the structure of the hypopy- 
gium. This and the following species, T. albimacula, have the 
pleural sutures well developed thus entirely separating the pleura 
from the other sclerites. Following Snodgrass, these species
