(1884) in submerged stems of the water dock, Rumex aquaticus Linn. 
The eggs are described as being rather long, white, and granulate. It is 
suggested that the developmental stages may be associated with water. 
The two local species have been reared and are discussed herewith. 
Rhamphidia mainensis Alex. 
1916 Rhamphidia mainensis Alex. Proc. Acad. Nat. Sci. Phila., p. 498-499, fig. 14. 
Rhamphidia mainensis appears to be a rather uncommon form, much 
rarer than f. flavipes, the other local species. Adult flies were not 
uncommon in the Basin Swamp, Orono, Maine, on June 12, 1913. This 
swamp is a low, sunken area surrounded on most sides by hills, opening 
into the ‘‘ Basin,” an affluent of the Penobscot River. Cold springs of 
water percolate down from these hillsides, and the soil is very wet, boggy, 
and richly filled with organic matter. The chief floral constituents are 
a few elms and white birches and an abundance of alders, Spiraea latifolia 
Borkh., and S. tomentosa Linn. The herbage consists of ferns such as 
Onoclea and Osmunda, patches of Iris, Impatiens biflora Walt., and many 
rushes and sedges. Crane-flies associated with R. maznensis on the 
date mentioned included the following: Dicranomyia _ haeretica, 
Epiphragma fascipennis, Pseudolimnophila lutecpennis, P. inornata, 
Limnophila fasciolata, L. macrocera, Pilaria recondita, Ulomorpha pilosella, 
Tricyphona inconstans, Erioptera vespertina, and Tipula sulphurea, also 
an abundance of Ptychoptera rufocincta and Bitiaéomorpha clavipes. 
Larvae were first found on April 20, 1917, in the dark, cold swamp 
known as Larch Meadows, south of Ithaca, New York. Here they 
occurred in the thick, black, saturated organic matter comprising the | 
soil of the swamp. ‘The vegetation consists of the dominant alder (Alnus 
incana |Linn.| Moench.), the poison sumac (Rhus Vernix Linn.), and 
the marsh marigold (Caltha palustris Linn.), as well as an abundance 
of other plant species in lesser numbers. The earthy material in which 
the crane-fly larvae were found was full of the organic remains of plants, 
such as ferns, leaves, alder catkins, and the like. Associated with these 
larvae at this time were numerous small hydrophilid beetles, and a great 
abundance of larvae of a dascillid beetle of the subfamily Helodinae, 
of various sizes and ages. Numerous tabanid and stratiomyiid larvae, 
and the larvae of the crane-fly species Bittacomorpha clavipes, Pseudolimno- 
phila lutecpennis, and Tipula dejecta, also occurred.
