Coloration dark brown; abdomen yellow, with a broad sublateral brown stripe on both 
sternites and tergites; abdominal segments beyond posterior row of spines brighter, more 
yellowish. 
Characters of head as in genus. Cephalic crest very small. Labrum broad. Pronotal 
breathing horns short, slightly curved. Mesonotal prescutum with fine transverse wrinkles; 
two blunt lateral tubercles, and behind these, on either side of median line, two smaller 
flattened ledges which are often bifid at their tips. (Similar ledges, but much less prominent, 
occur in 7. usitata.) 
Abdominal tergites with subapical armature weak, spines varying in number from six to 
eight, those of posterior segments larger; pleural spines long and slender, one on each ring; 
sternal spines powerful, four to six in number, no spines on base of posterior ring. Female 
cauda with sternal valves long and slender, but little shorter than tergal valves; dorsal lobes 
of cauda four in number, posterior pair very powerful, lateral pair smail, anterior median 
pair lacking.

Tipula ignobilis Loew 
1863 Tipula ignobilis Loew. Berl. Ent. Ztschr., vol. 7, p. 280. 
The adult flies of Tipula ignobilis are not common in collections, due 
in part to their retiring habits. The larvae, however, are common in 
their preferred habitat, saturated moss cushions. 
At Orono, Maine, numerous larvae were taken in wet moss on Jun 
17, 1913, associated with other larvae, such as those of Rhaphidolabina, 
Tricyphona, Pedicia, and Tipula nobilis. At Ithaca, New York, on Apri 
23, 1917, four very small larvae were found in wet cushions of moss (Ambly 
stegium). They grew very rapidly, emerging as adults on May 21 
On May 22 this moss was carefully examined and about thirty fully gro 
to rather immature larvae of this species were taken. They wer 
associated with equally numerous larvae of Dicranomyia stulta O. 5. A 
Needham’s Glen, the species occurred in the same moss that earlier 1 
the season harbored Tipula collaris and T. oropezoides. On June 1 
two teneral adults of 7. ignobilis were captured, in company wit 
Dicranomyia stulta, Geranomyia canadensis, Dactylolabis montana, an 
other species. The species is very common at the Indian Ladder, Helder 
berg Mountains, New York. 
Larva.— Length, 16.5-18 mm. 
Diameter, 2.5-2.6 mm.
