The Crane-Flies of New York — Part I 923 



Eriocera longicornis, E. cinerea, and E. spinosa arc 6n the wing in late 

 April and May, the last-named species flying in July. E. brachycera, 

 E. fultonensis, E. fuliginosa, and E. tristis are on the wing during the 

 summer months. 



Tribe Pediciini 



The genera of the tribe Pediciini may be separated in accordance with 

 the following key: 



1. Antennae with 16 segments 2 



Antennae with 13 or 15 segments 3 



2. Cord oblique; cell 1st Mi very short, pentagonal; size large, wing over 20 mm.; palpi 



elongated Pedicia Latr. (p. 923) 



Cord transverse; cell 1st Mi elongate; size smaller, wing under 18 mm.: palpi short. 



Tricyphona Zett. (p. 924) 



3. A supernumerary cross-vein in cell i?i Dicranota Zett. (p. 925) 



No supernumerary cross-vein in cell R\. (Genus Rhaphidolabis O. S.) 4 



4. Cell Ml absent Subgenus Plectromyia O. S. (p. 925) 



Cell Ml present 5 



5. Antennae 15-segmented; cell 1st Ms closed Subgenus Rhaphidolahina Alex. (p. 925) 



Antennae 13-segmented; cell 1st M- open Subgenus Rhaphidolabis 0. S. (p. 925) 



The recent accession of several curious new venational types in this 

 tribe indicates that the vein herein hold to be the radial cros.s-vein is 

 in reality the upward deflection of R2, which, in most species, is short 

 and transverse or but slightly oblique and is fused distally with /?i. 

 A detailed account of this venational peculiarity may be consulted else- 

 where (Alexander, 1918 d). 



Genus Pedicia Latreille

Pedicia is a small genus including six species, four of which are North 

 American. The species are among the largest of the Limnobiinae, and 

 with their conspicuous browu-and-white wings attract considerable atten- 

 tion. The larvae are carnivorous, living beneath moss in percolating 

 water and in cold springs (Needham, 1903 b: 285-286). There are two 

 regional species, both of which were originally described from Nova 

 Scotia by Walker. The following ke}^ divides the local species of Pedicia: 



Wings with the costal margin brown; vein Cih seamed with dark brown. [List Dipt. Brit. 



Mus., vol. 1, p. 37. 1848.] (Plate XLII, 175.) P. albiviita Walk. 



Wings with the costal margin brownish yellow; no brown seam on ^'ein Cu^. [List Dipt. 



Brit. Mus., vol. 1, p. 38. 1848.] (Plate XLII, 176.) P. contennim Walk.
