three setiferous spines on posterior ring, arranged transversely; spiracles very rudimentary 
opposite base of posterior ring; sternites with spines slightly more numerous and stouter 
near base of posterior ring two transverse spines on either side median line, the outermos 
setiferous. Male cauda on dorsum with six lobes; the four posterior ones stout, with tip 
spinous or those of ventral pair slightly bifid; the two anterior median lobes shorter an 
more slender; eighth sternite with four large spines about equally spaced; eighth pleurit 
with a large, powerful, acutely tipped lobe, and two or three smaller dorso-lateral spine 
above base of middle pair of dorsal lobes. Female cauda almost the same as male cauda 
due to the blunt terebral sheaths of this species. 
Nepionotype.— Ithaca, New York, March 30, 1917. 
Neanotype—— With type larva. 
Paratypes—— Numerous larvae and pupae, March 30 to April 18, 1917. 
Tipula nobilis (Loew) 
1864 Pachyrrhina nobilis Loew. Berl. Ent. Ztschr., vel. 8, p. 62. 
Larvae of T7pula nobilis were found in wet moss and beneath decayin 
witch-hazel leaves at Orono, Maine, on June 17, 1918. An adult emerge 
on July 1. A fully grown pupa found on July 11 attempted to transform 
but died after two hours without being able to extricate itself from th 
pupal case. 
The adults, which strikingly resemble some species of Nephrotoma, fl 
somewhat later than does T. collaris, but both species may be take 
together in early June. » 
T. nobilis is very similar in all respects to 7’. collaris. 
Larva.— Length, 20 mm. 
Diameter, 2.9-3 mm. 
Coloration, reddish brown. 
Spiracular disk as in T. collaris, the brown lateral margin to the lobes a little paler. An 
gills as shown in Plate XCII, 507. 
Head capsule almost as in 7’. collaris. Mentum with apical point elongate, with thre 
blunt teeth on either side. Hypopharynx with five moderately acute teeth. Antenna wit] 
a blunt conical papilla, larger and more conspicuous than in 7’ collaris. Mandible with teet 
very blunt. 
Pupa.— Length of cast pupal skin, about 18.5 mm. 
Pupa very similar to that of 7. collaris. 
Nepionotype.— Orono, Maine, June 19, 1913. No. 40-1913. 
Neanotype.— With type.
