similar lateral lobes that bear pencils of long, yellow hairs, these pencils 

 directed across the median line so as to lie almost in a straight line or 

 very broadly decussate. 



Habitat: Formosa. Holotype, cf, Musha, May 18-June 

 15, 1919 (T. Okuni, J. Sonan, K. Miyake and M. Yoshino). 



Tipula subapterogyne sp. n. 



Belongs to the arctica group; allied to T. serricauda Alexander; 

 praescutal stripes brownish black, much darker than the markings on 

 the remainder of the mesonotum; wings of the female semi-atrophied. 



Male — Length, 15.5 mm.; wing, 21.2-21.5 mm. 



Female — Length about 20 mm. ; wing, 6.8 mm. 



Frontal piolongation of the head gray, more reddish laterally; 

 nasus very long and slender ; palpi brownish black, rather short. Antennas 

 with the basal segment reddish, gray pruinose; second segment light 

 yellow; flagellum black; antennas of the male of moderate length. 

 Head yellowish gray, more rufous adjoining the inner margins of the 

 eyes; a narrow, dark brown median line. 



Mesonotal praescutum light gray with three dark brownish black 

 stripes; remainder of the mesonotum gray, each scutal lobe marked with 

 dark brown, the scutellum and postnotum with a capillary brownish 

 black median line. Pleura yellowish gray, indistinctly blotched with 

 darker. Halteres light brown, the knobs with the basal half dark brown, 

 the apical half yellowish. Legs with the coxae grayish yellow; trochanters 

 yellow; femora brownish yellow, the tips broadly black; tibiae brown, 

 the tips black; tarsi dark brown. Wings subhyaline, the costal and 

 subcostal cells more yellowish; wings marmorate with dark and light 

 brown; dark brown areas at the wing-base in cells R and M, at the 

 origin of Rs, at the stigma and thence along the cord to cell 1st M2; the 

 light brown areas include the broad wing-apex and extensive clouds in 

 cells R, M, most of Cui, the ends of Cu, 1st A and 2nd A; the sub- 

 hyaline areas appear as a broad, oblique crossband beyond the stigma, 

 extending from cell 2nd Ri across the inner ends of cells R2, Rs, R5, 

 through 1st Mo into the base of cell M^; a large area near the bases of cells 

 R and M; another beyond midlength of M; another before the stigma 

 in cells 1st Ri and R; other subhyaline areas in cells Cu and 1st A; cell 

 £nd A largely subhyaline; veins dark brown. Venation: Cell R2 

 large; vein R2 beyond r longer than R2+3; Rs long, about equal to R3; 

 petiole of cell Mi shorter than m; m-cu punctiform or obliterated. In 

 the female, the wings are considerably atrophied and the venation cor- 

 respondingly distorted; the wings are dark brown, paler basally and 

 along the costal region. 



Abdominal tergites yellowish with three conspicuous dark brown 

 stripes; segments six to nine more uniformly brownish; hypopygium 

 indistinctly more reddish brown; sternites yellow, with a conspicuous 

 median brown stripe. Male hypopygium relatively small. Eighth 

 tergite reduced to a mere strip at the median line. Ninth tergite small.
