like that on the wings of T. alia except that the brown is a little more intense. 

 Length 18 mm.; wing 20 nun. Coite Madera Creek, near Stanford University, 

 Cal., "i males, 1 female. Stanford University, 2 males, 1 female. 



Although the markings and general appearance of this species 

 are very like T. fallax, the structure of the lateral appendages of 

 the ninth sternite will enable one readily to separate them. 



Tipula newcomeri nov. sp. 



Brown: Head brownish yellow, with a broad, dorsal, brown stripe; rostrum 

 yellow; palpi brown, the last segment lighter; first and second joints of antennae 

 yellowish, others brown, cylindrical; collar light brown with three brown spots; 

 mesothorax light brown, with three brown stripes, each of which is divided by a 

 brownish yellow line; coxse and pleura hoary; scutellum and metanotum yellow- 

 ish brown with a narrow, median, brown line; hal teres brown; extreme base yel- 

 low; knobs darker brown; legs yellowish brown, tips of the tibiae, femora and tarsi, 

 darker; abdomen brownish yellow, with a broad dorsal brown line and narrow 

 interrupted lateral lines; posterior margin of each segment lighter; eighth tergite 

 almost wholly brown, lighter posteriorly; eighth sternite broad, somewhat pro- 

 duced posteriorly, posterior half, particularly the posterior margin and two light 

 colored areas on the posterior lateral angles, thickly covered with short, soft, yellow- 

 hairs; ninth tergite wholly brown, a little longer than wide, posterior margin 

 somewhat depressed and with a pair of short, black, downwardly-projecting, hook- 

 like processes; ninth sternite brown, completely divided below by a broad suture 

 which is filled with a white membrane; from the posterior lateral margins of the 

 suture arises a pair of rather long, thin, sharp-pointed, blade-like processes; lateral 

 margins with deep, oval incisions which are filled with a whitish membrane; the 

 points just above these bear a pair of appendages consisting of a slightly chitin- 

 ized base with three processes, the upper one spatulate and black-tipped, the mid- 

 dle one triangular, sharp-pointed, the lower one long, narrow and slightly curved 

 toward the tip; first pair of appendages broad, brown, tips rounded; second pair 

 rather flattened, edge and tips black; posterior margin of third pair with a deep 

 median incision dividing the appendage into two lobes, the lower one largest, yellow- 

 ish; the upper one oval, brown, with short brown hairs; the upper valves of the 

 ovipositor long, very slender, tips rounded, lower valves rather long, narrow, sides 

 parallel, tip rounded; wings with a brownish tinge, with several irregular whitish 

 spaces, and darker brown spots; two irregular whitish spots in the middle of the 

 second basal cell, the first sending an arm across the anal into the axillary cell, the 

 second sending an arm into the anal cell; the posterior half of the first basal cell, 

 the bases of both the marginal cells, the submarginal, and the first and fourth pos- 

 terior cells, whitish; discal cell, almost wholly whitish; distal portion of the first 

 posterior cell somewhat lighter, a brownish spot over the origin of the prsefurca 

 and a larger one over the stigma; veins brown. Length male 13 mm., wing 15 

 mm.; female 15 mm., wing 15 mm. Deer Park, California. Four males, four 

 females.
