Tipula Huron, sp. n. 



Related to T. submacidata Loew.; wings with a heavy brown 

 pattern. 



Male. — Length 14 mm.; wing 15.6 mm. 



Frontal prolongation of the head light yellow dorsally, more 

 infuscated on the sides below, palpi light brown, the apical seg- 

 ments somewhat darker. Antennae bicolorous, the flagellar seg- 

 ments beyond the first with the basal enlargement black, the re- 

 mainder of each segment dull yellow. Anterior part of the vertex 

 with three linear down dashes, the median one on the frontal 

 tubercle. Vertex dusky gray with a brown more or less interrupted 

 median line; occiput paler. 



Prgescutum pale gray with three broad, dark brown stripes, 

 the median one broadly bisected by a reddish brown line; thoracic 

 interspaces dull, infuscated; scutum light gray, the lobes brown, 

 scutellum and postnotum dull brownish yellow. Pleura clear, 

 light gray, the dorso-pleural membranes more yellow. Halteres 

 brownish, paler basally. Legs with the coxae whitish pollinose, 

 the anterior coxae more pink; femora dull yellow, the tips darkened; 

 tibiae dull yellow, the tips very narrowly darkened; tarsi brown. 

 Wings hyaline or sub-hyaline with the costal region more yellow; 

 a heavy brown and gray pattern arranged about as in T. angulata, 

 T. siibfasciata, etc. The brown areas including a large basal area, 

 a blotch at the origin of the sector, along the cord and the wing- 

 apex, all of these marks passing into gray on the caudal cells of 

 the wing; a broad, white fascia beyond the cord extending en- 

 tirely across the wing except the extreme apex of cell Ma. Vena- 

 tion: vein i?2 persists for its whole length. 



Abdomen dull yellow above, the tergites indistinctly ringed 

 caudally with silvery; tergites seven and eight, and the caudal 

 portion of six, infuscated; an interrupted sub-lateral brown line 

 extending from the middle of tergite two to the base of tergite 

 five; sternites dull yellow. Male hypopygium very similar to T. 

 suhmactilata, but the lateral points of the ninth tergites in the latter 

 species are usually shorter and less acute.
