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 Liquidambar, 

 Ilex opaca, Quercus michauxi, 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 albitarsis, common; Brachypremna dispellens, abundant, 

 many being heavily infested with a species of Trombidium; 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 11 

 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. 12
