NEW NEARCTIC CRANE-FLIES (TIPULID.E, DIPTERA) 
PART III. 
BY CHARLES P. ALEXANDER, CORNELL UNIVERSITY, ITHACA, N. Y. 
This paper is a continuation of the preceding articles under 
the same title (Can. Ent., vol. 48, p. 42-53, 1916; vol. 49, p. 22-31, 
1917). The species here considered include a small number of 
subapterous forms, these belonging to the genera Chionea, Lim- 
nophila, and Tricyphona. 
I am indebted to Mr. W. L. McAtee, Mr. R. C. Shannon, 
Mr. C. W .Johnson and other gentlemen mentioned in the paper. 
I am especially indebted to Mr. L. O. Jackson for specimens herein 
described. Unless stated otherwise, the types are in the collec- 
tion of the author. 
Subfamily LimnohihicB. 
Tribe Limnobiini. 
Genus Limnohia Meigen. 
Limnobia indigena jacksoni, subsp. n. 
Male. — Length 7.4 mm.; wing 8.8 mm. 
Female. — Length 7.1 mm.; wing 7.6-8 mm. 
Similar to typical indigena O. S. (Northeastern America), 
differing as follows: 
The medial praescutal stripes are continuous and well-defined 
behind, the interspaces obscure, not bright yellow; pleura largely 
dark brown, this including also the outer faces of the coxre. Wings 
similar, the ground-colour more grayish, the brown clouds less 
distinct and rhore extensive, pale grayish brown; these markings 
include a broad, continuous seam along and slightly before the 
cord and the apex of the wing; basal deflection of vein Cm close 
to the fork of M. Abdominal tergites with the cross-bands poorly 
defined, the sternites suffused with brownish. 
June, 1917.
