Holotype, cf , Simmons Woods, Gloversville, Fulton County, New 
York, altitude 900 feet, June 22, 1916 (Alexander). 
This is the first Eastern species that has the antennse elongated 
and cell Mi of the wings lacking at the same time. It bears a great 
resemblance to L. tenuipes Say, a species with cell Mi present and the 
venational details slightly different. 
The type was taken in a cold woods with decided Canadian floral 
tendencies, in association with the following Tipulidse: 
Dicranomyia puhipennis, Ormosia monticola, 0. rubella, Erioptera 
stigmatica, Gonomyia florens, Limnophila toxoneura, L. areolata, 
L. alleni, L. fuscovaria, L. munda, Adelphomyia minuta, Ula elegans, 
Rhaphidolabis rubescens, Tricyphona calcar, Tipula oropezoides, 
T. hermannia and T. monticola. 
I dedicate this species to Thomas Edward, the eminent Scotch 
naturalist, the story of whose life and struggles^^ in the interests of 
natural science has always done much to encourage me in this work.

cross-vein r at the tip of Ri and situated on R2; deflection of Ri+s 
arcuated, nearer the wing-root than is the r-m cross-vein; cell Mi 
absent; basal deflection of Cui variable in position, at the fork of M, 
just beyond the fork of M to about one-third the length of the cell 
1st M2.
