line; on disk, between spiracles, two indistinct dusky spots; lobes fringed with rather short, 
pale hairs which are narrowly interrupted between lobes. Spiracles irregular, roughly 
triangular. Anal gills four, slender, posterior pair the larger (Plate XCII, 506). 
Head capsule as in genus. Labrum and maxilla very densely fringed with long golden- 
yellow hairs. Mentum (Plate XCIII, 513) with two flattened lateral teeth, the median 
point elongated; mentum very deeply split behind. Hypopharynx (Plate XCIII, 514) with 
but three evident teeth, the lateral teeth very broad, flattened. (In some specimens these 
teeth are all very blunt, so that the anterior margin of the hypopharynx appears merely 
crenulate.) Antenna with apical disk very flattened. Mandible (Plate XCIII, 515) with 
a dorsal tooth and a powerful ventral tooth. 
Pupa.— Length: male, 12 mm.; female, 12.5-13 mm. 
Width, d.-s.: male, 1.6—1.7 mm.; female, 1.8-1.9 mm. 
Depth, d.-v.: male, 1.6 mm.; female, 1.7-1.8 mm. 
Coloration dark brown; dorsum of thorax and abdomen, and face, more reddish brown. 
General features as in Tipula collaris. Form slender. Pronotal breathing horns long 
and slender, dark-colored, divergent at tips. Antenna elongate. Wing sheaths ending 
opposite apex of second abdominal segment. Leg sheaths long, extending to beyond mid- 
length of fourth abdominal segment. Male cauda with dorsal lobes of genitalia short, blunt; 
ventral lobes produced caudad into slender, blunt lobes which are transversely wrinkled, 
separated by a U-shaped notch, at base on outside with a prominent spine. Female ovi- 
positor elongate; dorsal valves narrowed to the blunt tip; ventral lobes stout, a little shorter 
than dorsal valves, tips strongly divergent; the six dorsal lobes of cauda spinous-tipped, 
sharply pointed.

1823 Tipula collaris Say. Journ. Acad. Nat. Sci. Phila., vol. 3, p. 23. 
Larvae and pupae of Tipula collaris, a common vernal crane-fly, 
occurred frequently beneath saturated moss (Amblystegiwm trriguum 
[Wils.| B. & S.) in Needham’s Glen, Ithaca, New York, on April 17, 
1917. Their associates are noted under the account of T'. oropezordes 
(page 1001). In the same moss areas occurred numerous small red-backed 
salamanders (Plethedon cinereus), which probably fed on the insect deni 
zens of the place. Specimens emerged in the writer’s breeding Jars as late 
as May 10. 
The adults are on the wing during April and May, some persisting int 
early June in cool northern woods. The life history undoubtedly require 
a year for its completion. 
Larva.— Length, 21.5-25 mm. 
Diameter, 2.5-3.5 man.
