Edwards has decided that this insect and a few related species should be 

 placed in a new genus. The affinities of the fly, to judge from the details 

 supplied by Hudson, arc with the Epiphragmaria rather than with the 

 Limnophilaria, but until more details are forthcoming it cannot be defi- 

 nitely referred to that division. 



Limnophila {Phylidorea) ferruginea (Meig.), of Europe, is closely allied 

 to L. adusta (page 867), and is of especial interest as being the type of 

 the subgenus Phylidorea. It was reared by De Meijere (1916:204-206) 

 from larvae found living between saturated decaying leaves along the 

 banks of watercourses. Further mention of the species is made under 

 the discussion of the subgenus Phylidorea (page 866). 



Limnophila hyalipennis (Zett.), of Europe, was found by Bcling (1886: 

 198-199) in piny woods, where the larvae live in old ant hills or in piles 

 of earth thrown up by wagon wheels. The apparent lack of pupal breathing 

 horns in this species is discussed on page 755. The European species 

 L. lineola (Meig.) (Beling, 1879:54 and 1886:199-200), L. nemoralis 

 (Meig.) (Behng, 1886:200-201), and L. ochracea (Meig.) (Behng, 1886 : 

 202) are all found in damp earth along the margins of woodkmd streams 

 or in damp spots in the woods. Larvae of L. dispar (Meig.) were found 

 by Perris (1849:331) living in the hard, withered stalks of an umbellifer, 

 Angelica sylvestris Linn., where they hollowed out long passages in the 

 pith. (This reference is cited by Mik, 1881:204, and by Osten Sacken, 

 1869:201-202.) Limnophila pallida Bel. was reared by Beling (1873 a: 

 557) from larvae living in a decaying ash trunk. 



The reference to Limnophila platijptera Macq. given by Heeger (1854) 

 is considered })y Osten Sacken (1869:4, 202) to refer to a mycetophilid, 

 probably Bolitophila. 



The American species that are now known are considered in the 

 following pages. In addition, Limnophila unica 0. S. has been bred from 

 larvae found in decaying wood. 



It is very probable that some of the species listed above, as well as 

 many of the limnophiline forms that are still unknown as regards their 

 immature stages, will be found to belong to some one or other of the 

 remaining divisions of the tribe, rather than to the Limnophilaria as here 

 restricted. This group requires more careful study than does any other 

 division of crane-flies.
