JOHNSON: NEW TIPULIDAE. 125 
Limnobia fallax new species. 
Limnobia solitaria Johnson, in Smith's Cat. insects N. J., p. 630, 1900 
(non Osten Sackcn). 
(5^, 9 • — Head dark brown above, yellowish below; antennae dark 
brown, the basal joints of the flagellum light brown. Thorax reddish 
yellow with four obscure dark brown stripes; pleurae, seutellum, and 
metanotum yellow, the last margined with stripes of dark brown. 
Abdomen yellowish obscurely banded with brown on the posterior 
portions of the segments, less prominent in the female; h\']Jopygium 
and ovipositor reddish. Halteres dark brown. Femora yellowish, the 
brown on the apical third divided by a light yellow band; tibiae 
brown, basal portions yellow, tarsi brown. Wings yellowish, with 
dark brown spots along the anterior; those in the first basal cell vary- 
ing in size, and in number from three to seven. There is a large spot 
at the junction of the radial section (praefurca), one at the end of 
the subcosta extending obliquely across the inner end of the submargi- 
nal cell, and another at the end of the radius, the last ocellated. 
Length, c^, 6 mm.; 9 , 7 mm. 
Three specimens: tyj^es, c?, Dunnfield Creek, Delaware Water 
Gap, New Jersey, July 14, 1898; 9, Morton, Delaware Co., Penn- 
sylvania, May 8, 1892, both in the author's collection. 
From the description this was inadvertently referred to L. solitaria 
Osten Sacken, in the list of New Jersey Diptera. Since that time I 
have collected numerous specimens of L. solitaria (which is really a 
boreal species) and find that the two are distinct. It is distinguished 
from L. solitaria by its smaller size, darker antennae, less conspicuous 
thoracic stripes, and porportionately narrower wings. 
Limnobia parietina (Osten Sacken). 
Of this beautiful species (which has only been recorded from 
Trenton Fall, New York, and the White Mts., New Hampshire), 
I have the following additional records: Prouts Neck, Maine; Inter- 
vale, New Hampshire, Sept. 15 (Dr. G. M. Allen); Hampton, New 
Hampshire, Sept. 9 (S. A. Shaw); and Lake Ganoga, North Mt., 
Pennsylvania, Aug. 28, Sept. 1, 1897 (C. W. Johnson).
