Figs.— Alexander, Cfls. N. Y., 1, pi. 50, fig. 277 (hyp.) ; 1919. Dickinson, Cfls. 

 Wise, p. 234, fig. 148 (wing), p. 249, fig. 183 (hyp.) ; 1932. 



Antennae ( S ) with flagellar segments strongly nodose, uniform- 

 ly darkened. Praescutum with four stripes that are narrowly bor- 

 dered with brown. Wings brown, with three major white areas, in- 

 cluding an incomplete band beyond cord and isolated areas near outer 

 end of cell M and before midlength of cells Cu and 1st A. Median 

 dark stripe on abdominal tergites rarely obsolete. Tergite of hypo- 

 pygium (Fig. 30, K, 9t) ; appendage of eighth sternit« (Fig. 30, K, 

 8s). $. L. 15-16 mm.; w. 14-16 mm.; antenna, 5-5.5 mm. ?. L. 18- 

 23 mm. ; w. 15-16 mm. 



(Late May, June) Ont., Que., Lab., Me., N. H., Vt., Mass., R. L, N. Y., westw. to 

 Minn., Wise, Sask. and Alta. 



Connecticut.— Portland, May 23, 1930 (M. P.Z.); Storrs, 1932 (C. S. C.) ; Union- 

 ville, June 10, 1904 (W. E. B.) ; Winsted, June 10, 1928 (R. B. F.). 



T. discolor is here considered as being the same as serta. The 

 wing-pattern of the unique female type is practically the same as in 

 serta but the median praesciital stripe is entire. 



T. {Oreomyza) stylifera Dtz, 



1921. Tijmla stylifera Dietz ; Trans. Amer. Ent. Soc, 4T : 264-265. 



Praescutum with four grayish brown stripes that are narrowly 

 margined with darker; interspaces with brown punctures. Pleura 

 grayish white, variegated by pale brown areas. Femora dusky yel- 

 low, tips slightly darker. Pale crossband beyond cord extending to 

 midlength of cell Mz. Abdominal tergites yellow, without median 

 dark stripe except on segment two; lateral borders whitish; a vague 

 sublateral darkening. $ . L. 14 mm. ; w. 18 mm. 



(June) Pa. Still known only from the unique type. 



T. {Oreomyza) subfasciata Lw. 



1863. Tipula suhfasciata Loew; Berlin. Ent. Zeitschr., 7:282. 



Figs.— Alexander, Cfls. N. Y., 1, pi. 48, fig. 248 (wing) ; 1919. Dickinson, Cfls. , 

 Wise, p. 232, fig. 140 (wing), p. 248, fig. 174 (hyp.) ; 1932. 



Flagellar segments not excised. Head with median dark vitta. 

 Legs yellowish brown, the individual segments undarkened. Wings : 

 narrow; Rs very long, nearly three, times m-cu\ petiole of cell Mi 

 short. The hypopygium as figured by Dickinson (possibly not cor- 

 rectly determined) is much as in angulata but median tergal notch 

 without basal denticle. $ . L. about 12 mm. ; w. 15.5 mm. 



Hudson's Bay Region; N. S., Wise. 



T. (6'r6(97?^?/.?a) neptun Alex. (Fig. 30, L). 



1921. Tipvia neptun Dietz ; Ent. News, 32 : 300-301. 



1928. Tipvia suhserta Alexander ; Can. Ent., 60 : 97. 



Close to serta, differing most decisively in hypopygial characters. 

 Abdominal tergites rich reddish brown, the median stripe lacking.
