3 16 mm., 2 20 mm.; wings of 5’ 18 mm., of 2 10mm. 50%, 6 2 collected by 
Mr. F. X. Williams near San Francisco. 
Tipula silvestra n. sp. Cinereous; head cinereous with a more or less distinct 
median brown stripe above; rostrum darker; palpi dark brown, yellowish at the 
base; antennae brown, segments one and two and the basal half of three yellow; 
thorax cinereous, dorsum with four rather broad brown stripes, lateral ones inter- 
rupted anteriorly; scutellum and metanotum with a more or less distinct median 
brown line; halters yellow, knobs brown; legs rather stout, yellowish brown; tarsi 
and tips of femora and tibia darker; abdomen cinereous with dorsal and lateral brown 
stripes; ovipositor dark reddish brown, upper valves acute, almost straight when 
viewed from the side, decidedly arcuated near the tip when seen from above; lower 
valves broad, ending in a sharp corner above, obtusely rounded below; wings much 
reduced and distorted, but little longer than the halters with more or less distinct, 
complete veins; length 2 26 mm.,wing4mm. ‘Two & collected at Pacific Grove, 
Cal., by Mr. Ewal Newcomer, and 1 2 from Stanford University. 
This species looks very much like 7. vestigipennis Doane and the specimen 
from Stanford University, being in bad condition, was placed with this species, but a 
comparison with the two females from Pacific Grove shows it to belong with them. 
T. silvestra differs from T. vestigipennis in being cinereous instead of brownish or 
yellowish, and in the shape of the valves of the ovipositor. In vestigipennis the upper 
valves are straight when viewed from above as well as from the side, and the lower 
valves are narrower and obtusely rounded at the tip. 
Tipula quaylii n. sp. Brown; head brown with a somewhat hoary bloom; a 
more or less distinct darker stripe above; rostrum short not longer than the head, 
brown, darker above; palpi brown, last segment darker, equal in length to the three 
preceding segments taken together, antennae wholly brown, 3rd segment almost 
as long as the first; thorax reddish or grayish brown, dorsum with a median darker 
brown stripe; pleura, coxae and metathorax hoary; wings reduced to mere irregular 
shaped pads less than 4 the length of the halters, halters rather long and slender, 
brown; legs with a short, dense, black pubescence, rather stout, brown; tarsi and 
tips of the femora and tibia darker; abdomen brown, with a rather distinct broad 
brown stripe above; hypopygium rather small; 9th tergite with a median groove 
and with a broad deep U-shaped incision from the middle of which arise two short 
sharp close cut processes; 9th sternite almost completely divided by a narrow deep 
V-shaped incision; first pair of appendages spatulate; second pair claw shaped and 
strongly chitinized at tip; upper valves of ovipositor curiously twisted in such a way as
