At Camp Perry, Onslow County, North Carolina, July 9, 1915, 
on a small branch of the New River. The flies occurred in a typical 
sweet-gum swamp, the dominant forest cover being the Liquidamhar, 
Ilex opaca, Quercus rnichauxi, Acer rubrum, Fraxinus sp., with 
considerable Liriodendron and a little Pinus tceda, growing in very wet 
to moist soil, and the undergrowth was very rank and luxuriant, 
consisting of the all-dominant lizards-tail, Saururus cernuus, from 
which plant the flies were swept; other plants, as Osmunda regalis, 
Onoclea sensibilis, Carpinus caroliniana and Callicarpa americana, 
being common. The following crane-flies were associated with this 
species : 
Gonomyia sulphurella, rare; G. manca, common; Gnophomyia 
■tristissima , uncommon; Epiphragma solatrix, rare; Limnophila 
macrocera, uncommon; L. tenuipes and luteipennis abundant; Pen- 
thoptera alhitarsis, common; Brachypremna dispellens, al^undant, 
many being heavily infested with a species of Tromhidium; Oropeza 
subalbipes, rare; Tipula tricolor, common; T. perlongipes, rare; 
Bittacomorpha clavipes and Ptychoptera rufocincta, common. 
It should be here noted that there is a Polymoria irrorata Philippi^^ 
that in all probability is a Limnophila and prior to the present 
species. This apparent status of Polymoria has been pointed out 
by the author in another paper.^^
