^ the length or width of those of the d\ otherwise they are fully developed. Length 

 cT 16 mm., 9 20 mm.; wings of cT 18 mm., of 9 10 mm. 5cT, 6 $ 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 $ 26 mm., wing 4 mm. Two $ collected at Pacific Grove, 

 Cal., by Mr. Ewal Newcomer, and 1 $ from Stanford University. 



. This species looks very much like T. 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 \ 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
