Inner pleural appendage complex, consisting of a slender caudal lobe which is directed 
backward and pointed, and a cephalic lobe which is compressed, black, and heavily 
chitinized along the margin; coloration yellowish; antennae bicoiorous; head light 
gray; thoracic stripes rather indistinct, brownish orange; ninth tergite (Plate LII, 
312) with the lateral angles tipped with a cylindrical, conical point; median lobe 
prominent, convex, rounded; eighth sternite large, prominent, projecting caudad, 
the posterior margin with a rounded notch bearing a dense tuft of long, silvery hairs 
on each side of the mid-line; wing of male 18-19 mm. [Proc. Acad. Nat. Sci. Phila.,

103 Lobes of ovipositor ‘blunt, unchitinized...........0.....045........... bicornis group 
Lobes of ovipositor pointed, chitinized .. . . Females of other species with unmarked wings 
No attempt is made here to separate the females of the species with unmarked 
wings; many of the species have not been definitely associated with their mates and 
are not really known. Im all cases in which pairs of flies are taken in copula, the two 
sexes should be pinned on the same pin, the male above. In many groups of the 
genus it is quite impossible to separate the females on the characters known at 
present. 
Since the above key was completed a few additional species of Tipula 
have been described. These are briefly diagnosed here in order to ecom- 
plete the data. 
Tipula aprilina Alex. (Alexander, 1918 a:63-64.) 
Dejecta group; close to TJ. dejecta. Male hypopygium with the ninth tergite large, 
the posterior margin with the lateral angles produced caudad into prominent blunt lobes 
which are blackened and furnished with small tubercles, the caudal margin truncated; between 
these lateral lobes two parallel, usually longer and slightly pointed, lobes which are 
directed slightly ventrad, one on either side of the median line; outer pleural appendage 
very small and inconspicuous, elongate-cylindrical, yellowish; inner pleural appendage 
elongate, narrow; margins of ninth sternite not widely separated beneath, carinate, and with 
a narrow V-shaped posterior notch bearing a pair of small, fleshy lobes. Wing of male, 
11.5 mm. (Virginia, April.)
