Genus PEDICIA Latreille. 



PEDICIA ALBIVITTA Walker. 



Spring Hill, Virginia, September 21, 1911; Rosslyn, Virginia, 

 October 6, 1912, F. Knab; Falls Church,' Virginia, September 17, 

 1919, at light, L. O. Jackson; Thrifton, Va., October 15, 1919, in 

 spider web, McAtee ; Cleveland Park, District of Columbia, Septem- 

 ber 17, 1906, E, A. Preble. The immature stages are semiaquatic, 

 living in cold springs, in saturated moss, and in similar situations. 

 Practically all of the adults taken here have come to light or have 

 been found in spider webs. Alexander has caught two species at 

 light, and has found them sitting on tree trunks by day; the indi- 

 cations are therefore that Pedicia is crepuscular or nocturnal in its 

 activities. 



Genus TRICYPHONA Zetterstedt. 



KEY TO SPECIES. 



1. Cell 7?3 of the wings short petiolate; m^cu obliterated by the fusion of Cui 



with Mz; general coloration yellowish; wings with the costal region dark- 

 ened T. inconstans (p. 430). 



Cell Ri of the wings broadly sessile ; ?n-CM present or barely obliterated by 

 the fusion of Cui with M^; general coloration gray; wings with brown or

2. Antennae with the basal segments dull yellowish, notably brighter than the 



black flagellum ; wings with a brownish tinge, marked with pale brown 

 spots along the costal margin and pale gray clouds at the ends of the 

 longitudinal veins ; the mark at the origin of the sector does not pass into 

 the costal cell; cell J/i sessile or very short petiolate—T. renialis (p. 430). 

 Antennae black throughout ; wings nearly hyaline, with large brown spots 

 along the costal margin, the mark at the origin of the sector passing into 

 the costal cell; cell Mi long petiolate T. macateei (p. 430). 



The immature stages are spent in moist earth.
