1 62 Psyche [October 



wing; first posterior cell almost wholly white, the base and a spot along the ante- 

 rior margin about the middle being brown. Length, 15 mm., wing, 17mm. Key- 

 port, Wash., 9 males, 2 females; Olympia, Wash., 1 female. 



The liypopygiura of T. fallax differs from T. alia in the follow- 

 ing particulars: The blade-like processes arising from the pos- 

 terior incisions of the ninth sternite are broadly triangular, the 

 tip ending in a sharp backward curved claw; the pendulous appen- 

 dage has but two arms, the middle one being represented by a 

 very short projection, the lower arm is shorter and more slender; 

 there are also other less conspicuous differences but these will 

 serve to separate the two species. 



Tipula madera sp. nov. 



Brownish : Head brownish yellow, with a faint median and plainer lateral brown 

 lines above; rostrum yellow, with brown stripes laterally; palpi brown, lighter 

 toward the tips; first and second and the extreme base of the third segment of the 

 antennjp, yellow; others, brown; mesonotum grayish pruinose, the usual three 

 brown stripes divided in such a way as to appear as eight separate lines, the lateral 

 pairs uniting anteriorly; metanotum and scutellum grayish with a median brown 

 line, scutellum with brownish spots on the sides; pleura grayish pruinose with a 

 distinct brownish line reaching from the neck to the base of the wings, lower half 

 of sternopleura and the margins of the hypopleura brown; halteres yellow; knobs 

 brown, tips whitish; legs brownish yellow; tarsi and the tips of the femora and 

 tibia darker; abdomen light brown with distinct median and lateral, interrupted, 

 brown lines; eighth sternite brown, yellowish posteriorly, posterior margin with 

 two deep incisions making three distinct lobes, which are covered with short, thick, 

 yellowish and brownish hairs; hypopygium much elongated as in T. fallax and 

 T. alia; ninth tergite brown somewhat narrowed posteriorly, posterior margin 

 more strongly chitinized, the median portion produced into a short, broad, three- 

 pointed, downward-projecting tooth; ninth sternite brown, yellowish posteriorly, 

 di\'ided ventrally by a broad more membranous area, no pleural sutures; posterior 

 margin with a broad crescent-shaped incision, from the middle of which arises a 

 pair of long strap-like appendages, the inner edges of which are straight, parallel; 

 the outer edges bisinuate; lateral margins with deep oval incisions which are filled 

 with a whitish membrane; the points that project just above these incisions bear 

 a pair of quadrate, weakly-chitinized appendages, the posterior margins of which 

 are deeply notched; the two triangular teeth thus formed are more strongly chitin- 

 ized and slightly incurved toward the tips; first pair of appendages but little longer 

 than broad; upper edge of second pair of appendages divided into two strongly 

 chitinized unequal teeth; third pair membranous with the base broadly joined to 

 the second; upper valves of ovipositor of female long, narrow, obtusely pointed; 

 lower valves reaching to or beyond the middle of upper valves; wings brownish 

 with several whitish hyaline spots in nearly all the cells, making a pattern exactly
