170 THE CANADIAN ENTOMOLOGIST 



Habitat.— New York (Suffolk County). 



Holotype. — cf , Yaphank, Long Island, September 3-4, (Charles Schaeffer). 



Paratopotype.- — cf • 



Type in the collection of the Brooklyn Museum. 



Tipula phoroctenia, new species. 



Belongs to the marmorata group, closest to T.fragilis Lw.; male hypopygium 

 with the ninth tergite having a broad V-shaped notch; outer pleural appendage 

 without a basal tooth; eighth sternite strongly projecting, shovel-like, the pos- 

 terior margin shallowly notched and with a row of black, comb-like spines. 



Male.- — ^Length about 13 mm., wing 14 mm. 



Similar to T. fragilis Lw. in most respects, differing as follows : The 

 praescutal stripes are broader and less distinct, the intermediate pair extending 

 a little farther cephalad, the grey thoracic interspaces narrower. The wings 

 are a little narrower, with the dark pattern less distinct. The abdomen is 

 light yellow with a narrow, dark brown sublateral stripe and silvery grey lateral 

 margins. The ninth tergite and the sixth to ninth sternites are dark brown. 

 The most conspicuous differences are to be found in the structure of the male 

 hypopygium, the ninth tergite of which has a broad, posterior V-shaped notch 

 the caudal margin blackened, with the lobes running out into slender, chitinized 

 points, the space between with a few smaller elevations; lateral notches ex- 

 tensive, not so deep as in T. fragilis. Outer pleural appendage long, slender, 

 somewhat flattened, without a distinct chitinized basal ridge or tooth as in 

 most other species of the group. The fleshy lobes that arise near the ventral 

 angle of the pleurites are very large so that they practically fill this portion of 

 the opening of the genital chamber; they are pale reddish, covered with a short, 

 dense pale pubescence. Ninth sternite with a Broad square notch, from the 

 base of which projects a stout, reddish rod, presumably the penis-guard. Eighth 

 sternite extensive, projecting, the posterior margin nearly truncated with a 

 very shallow notch, set with a row of short, black spinous teeth; extreme pos- 

 terior lateral angles of the sternite with a few long yellowish hairs. 



Habitat. — Maine. 



Holotype. — cf, Orono, Penobscot Co., in a bog at the edge of a wood, 

 October 3, 1913, (H. M. Parshley). 



Paratopotype. — cf , indoors, October 16, 1913. 



Type in the collection of the author. 



Tipula nebulipennis, new species. 



Belongs to the marmorata group, closest to T. fragilis Lw.; legs mostly 

 brown with only the femoral bases yellowish; male hypopygium having the 

 caudal margin of the ninth tergite with two flattened divergent lobes separated 

 from one another by a very small notch ; outer pleural appendage with a subacute 

 shiny chitinized tooth; eighth sternite slighlty projecting, the posterior margin 

 with a broad, U-shaped median notch. 



If a/e.— Length 12-13 mm.; wing, 12.2-13.5 mm. 



Frontal prolongation of the head dark grey, the sides more brownish, 

 palpi short, brownish black. Antennae with the scape yellow, the flagellum 

 brownish black; flagellar segments only slightly enlarged basally. Head grey.
