Tipula olia sp. nov. 



Brown: Head grayish with faint median and lateral brownish lines; rostrum 

 yellow with brown stripes laterally; palpi, brownish yellow, darker toward the base; 

 first and second segments of the antennje yellow, others brown; mesonotum with 

 three broad brown stripes, the median one is entirely divided by a broad fusiform 

 grayish line, the lateral stripes are also marked but not completely divided by a 

 broad gray line; metanotum and scutellum yellowish gray, the latter with two 

 faint brown spots; pleura grayish with a rather distinct brownish line reaching 

 from the neck almost or quite to the base of the wing; halteres brownish, knobs 

 darker, base yellowish; legs yellowish; tarsi and tips of femora and tibite darker; 

 abdomen yellowish brown, with interrupted median and lateral brown lines; pos- 

 terior margin of each segment grayish; eighth sternite wholly brown, produced 

 posteriorly and ending in three blunt conical projections which are covered with 

 thick short yellow hairs; hypopygium (see Snod. fig. of T. fallax) much elongated; 

 ninth tergite brown, lateral margins converging slightly, posterior margin strongly 

 chitinized, extreme tip produced downward into two short sharp curved claws; 

 ninth sternite brown, lighter posteriorly, no pleural sutures, posterior ventral mar- 

 gin deeply notched and provided with two long, slender, sinuous, blade-like proc-

esses; lateral margins of the sternite with deep oval incisions which are filled with 

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

 of pendulous appendages which are made up of a somewhat quadrate basal portion 

 and three arms, the upper and middle arms are short incurved, claw-like and chiti- 

 nous at the tips, the lower arm is long, slender, pointed and membranous; the first 

 pair of appendages are a little more than twice as long as wide with the tip bluntly 

 rounded; the second pair of appendages consists of a membranous basal portion 

 and two strongly chitinized lobes, the largest one triangular and sharp pointed, 

 the smaller one rounded at the tip; the third pair is membranous, roughly quadrate, 

 broadly joined to the middle appendage; the upper margin is provided with fine 

 short hairs and a weakly chitinized ridge sets off a small darker lobe on the poste- 

 rior dorsal corner; the females that I think belong with this species have the upper 

 valves of the ovipositor long, slender and blunt at tip; lower valves shorter, broad, 

 obtuse; wings, brownish with several whitish hyaline spots in nearly all the cells; 

 a whitish, hyaline, interrupted band beginning in the anterior margin just beyond 

 the stigma extends through the submarginal, first posterior and discal cells and 

 along the edges of the fourth and fifth posterior cells to the posterior margin of the
