1921] Dietz: Impudica Group of Tipula 5 
the margin is deeply emarginate, the inflexed portion ends in a spine; 
the subtergal process is long, laterally compressed and very acute. 
Ninth sternite with deep, U-shaped emargination. Pleurites ample, 
subtruncate, emarginate, each end of the emargination ends in a claw- 
shaped, inward bent hook. The lower apical appendages are long, 
narrowly lanceolate, somewhat twisted and extend considerably beyond 
the ninth sternite. 
Female.—Length 21 mm.; wing 16.5 mm. The dorsal abdominal 
stripe entire on tergite one, indicated by a median dash anteriorly on 
segments two to six; lateral margin of tergites conspicuously white and 
a large, lateral, fuscous dash on each segment; tergites two to seven 
with a transverse line each side, anteriorly; venter paler; hirsutity in 
conspicuous. 
Holotype— o. Vineyard, Utah; June, 1912, (T. Spalding). 
Allotype— 9. Silver City, New Mexico, May 24, 1913. 
Paratypes—1o. Platt Canyon, Colorado, June 27, 1915. 
20 o', Clear Creek, Colorado, June 23, 1914 (Oslar); 30° of and 
29 9, Silver City, New Mexico, May, 1913. 
A very distinct species. Its nearest ally is T. lyrifera, which 
it closely resembles in the lower apical appendages, but from 
which it is distinguished in its general darker coloration, grayish 
wings, cell C. concolorous and the fuscous spot at the origin of 
R. s. and at the end of the S. c. vein. 
Tipula lyrifera spec. n. 
Yellowish. Wings pale. Ninth tergite of hypopygium with deep, 
narrow incision, its canthi obtuse; lateral lobes with deep, rounded 
emargination; lower apical appendages elongate-lanceolate, twisted, 
conspicuously prolonged beyond the ninth sternite. 
Male.—Length 17.5 mm.; wing 17 mm. 
Head: Rostrum yellow, frontal prolongation beset with short, 
black hairs; nasus scarcely indicated. Palpi yellowish, light fuscous 
outwardly. Face and occiput yellowish with whitish pollinosity and 
darker median line. 
Thorax light, grayish-yellow. Pronotal scutum infuscate in the mid- 
dle; scutel pale yellow. Prascutal lines light brown, the inner pair 
almost obsolete posteriorly; sides of preescutum light brown. Scutum 
concolorous, an elongate light brown patch along the median line, 
another, irregular, curved line externally. Scutel and postnotum slightly 
darker, the former with an obscure, the latter with a distinct, median 
fuscous line. 
Pleura sordid yellowish, with grayish-white bloom. Legs slender, 
yellowish; hairy vestiture dense, short, blackish. Femora and tibiz 
lightly infuscate at the apex, tibiz conspicuously longer than the 
metatarsi; tarsi yellowish-fuscous.
