June, igiS.] ALEXANDER: New CrANE-FlIES FROM AsiA. 73 



short and powerful ; cox?e dark gray ; trochanters brown ; femora strongly 

 incrassated, reddish-brown, the tips dark brown ; tibis brown, the spurs very 

 long ; tarsi very short, brown. Wings greatly atrophied, short and broad, 

 about equal in length to the halteres, appressed to the postnotum. 



Abdomen reddish with a broad black median stripe on the dorsum that is 

 almost continuous, lateral stripes less distinct. Ovipositor with the dorsal 

 basal shield blackened, heaxiiy chitinized ; the dorsal valves of the ovipositor 

 slender, divergent, reddish horn-colored ; sternal valves short, the tips pointed. 



Habitat: Northeastern Siberia. 



Holotype, J, Plover Bay, Siberia, July ii, 1899 (Dall). (The 

 Harriman Alaska Expedition, 1899.) 



This species is close to T. zvhifneyi Alex, of the Pribilof Islands, 

 off the Alaskan coast. This latter species, however, has the eyes 

 much larger and more protuberant ; the antennae much more elongate, 

 the third segment especially being much longer; the praescutum is 

 without distinct stripes, the second antennal segment reddish, etc. 



Tipula subcentralis new species. 



Male. — Length 20 mm. ; wing 20.5 mm. 



Frontal prolongation of the head elongate, pale brown, thinly dusted with 

 gray; nasus stout; palpi light brown. Antennae with the scalpal segments and 

 the first flagellar segment light yellow ; remaining segments of the flagellum 

 with the enlarged base black, the stem yellow, on the apical segments becom- 

 ing more dusky; flagellar segments rather deeply incised, the enlarged bases 

 a little shorter than the apical swelling of each segment. Head gray, the 

 tubercle on the vertex more reddish ; a very narrow median brown line extend- 

 ing the length of the head. 



Mesonotal praescutum light gray, the usual stripes concolorous, narrowly 

 and somewhat indistinctly margined with brown, the broad median stripe 

 bisected by a brown line ; thoracic interspaces with a few short setre, set in 

 black punctures ; pseudosutural foveje large, triangular, pale in color ; scutal 

 lobes gray; scutellum pale brown, with an indistinct median stripe; post- 

 notum brownish, thinly dusted with gray. Pleura gray, the dorso-pleural 

 membrane more yellowish. Halteres pale, the knobs brown. Legs with the 

 coxae dull brownish-yellow, thinly dusted with a gray pollen ; trochanters yel- 

 low ; femora yellow, a little darkened at the tip ; tibiae yellowish-brown, tipped 

 with darker; tarsi brown, the tips of the metatarsi dark brown. Wings with 

 a brown, gray and whitish pattern, the ground color brown ; a large white 

 area beyond the stigma; apex of cell 7?^ white; a large irregular blotch before 

 the cord, extending across the sector and across cell ist M. nearly to the wing 

 margin; a large white area on cell M and another near the base of the wing; 

 basal half of anal cells conspicuously whitish. Venation: Rn persistent; Rs 

 elongate ; petiole of Mi a little longer than m ; m-cu obliterated or punctiform. 



Basal abdominal tergites rich yellow, with a broad median brown stripe, 

 on the fifth to seventh segments expanded to include most of the segments;
