New Species of Crane-Flies from the 
United States and Canada 
(Tipulide, Diptera). 
By Charles P. Alexander, State Natural History Survey, Urbana, Illinois. 
Most of the new species described in the present paper were found among material 
sent to the writer for identification. I am greatly indebted to Mr. W. L. McAtee and 
to Mr. F. R. Cole for the privilege of studying and describing many of the species 
included in this paper. Two interesting forms were collected in southern Illinois 
during the season of 1919 by Mr. Malloch and the writer. 
Family Tipulide. 
Subfamily Limnobiine. 
Genus Dicranomyia Stephens. 
Dicranomyia terre-nove sp. n. 
General coloration gray, the prescutum with three dark brown stripes; antenne 
dark brown throughout, the flagellar segments short-oval; wings with a heavy dark 
brown pattern, including five large costal blotches; Sc short, basal deflection of Cul 
far before the fork of M. 
Male.—Length about 5.5 mm.; wing, 7.6 mm. 
Female.—Length about 7.5 mm.; wing, 7.7 mm. 
Rostrum dark brown; palpi brownish black. Antenne dark brown, the flagellar 
segments short-oval, clothed with an abundant pale pubescence. Head bright silvery 
on the front, duller on the posterior parts of the head; a conspicuous brown line on 
the vertex. 
Pronotum dark brown. Mesothorax very deep, the mesonotum gibbous. Mesonotal 
prescutum light gray with three conspicuous dark brown stripes, the broad median 
stripe indistinctly split by a capillary line; scutum gray with the lobes dark brown; 
scutellum and postnotum gray, the latter with a delicate brown median line. Pleura 
light gray with an indistinct brownish longitudinal stripe extending backward from 
the fore coxe; a similar line on the mesosternum. Halteres yellow, the knobs dark 
brown. Legs with the coxe small, gray; trochanters dull yellow; femora brownish 
yellow, the tips indistinctly darker; tibie and tarsi brown. Wings whitish subhyaline 
with a heavy brown and grayish pattern, as follows: five dark brown blotches along 
the costal margin, the first near the wing-base, the third at the tip of Sc and the origin 
of Rs, the fourth at the tip of R/, the last at the tip of R2+3, suffusing the wing-apex; 
the first three of these markings reach the costa and pass into cell R; the fourth 
(stigmal) is rectangular, connected with a blotch at the fork of Rs; narrow brown 
seams along the cord and the outer end of cell 7st M2; large brownish gray clouds 
along the margin at the ends of the veins and at the anal angle of the wings. 
Venation: Sc short; ending just beyond the origin of Rs, Sc2 indistinct, apparently 
somewhat removed from the tip of Sc, this distance about equal to the basal deflec-
