auditory foramina on both faces of the cephalic tibiae, while all of 

 the other specimens have this organ only present on the external 

 face of these members. 



Wingless females of this species are very similar to the largest 

 females before us of Falcicula hebardi, but are readily distinguished 

 by the presence of auditory foramina on the external face of the 

 cephalic tibiae and, though distinctly more compact than exigua, 

 are not as compact as hebardi. Some variation in the propor- 

 tions of the caudal tibiae is found, and though the length appears 

 to vary chiefly with the size of the insect, long-winged individuals 

 indicate that in these this measurement proportionately averages 

 slightly greater. Extremes in length of caudal femora in material 

 before us: wingless, cf 4.1 to 5, 9 4 to 4.9; winged, d 71 4.7 to 5, 

 9 5 to 5.2 mm. 



This insect does not appear to climb up in high grasses and weeds 

 as much as exigua does, but prefers low grasses, particularly in wet 

 locations. It was taken in undergrowth near a "branch" (Florence), 

 in wet undergrowth of pine woods (Yemassee, Gainesville), in 

 moderate numbers in low grass on edge of salt marsh (Tybee Island) , 

 in "hammock" near stream (Thomasville), common on swampy 

 ground in tangles of low weeds and some raspberry vines, in woods 

 composed mainly of deciduous trees (Beaumont) and not common in 

 undergrowth of pine woods (Dickinson). 



The above records define the known limits 174 of the species' dis- 

 tribution in the United States. 175 Numerous records in the literature, 

 of this species from more northern localities, apply without exception 

 to exigua, which name was for a long time incorrectly referred to 

 the genus Nemobius.

174 The authors' previous record of a single specimen from Key West, Florida, 

 was based on the specimen here correctly recorded under A . vittata. 



175 We have thought best to record here all of the material of the species before 

 us from the United States, in order to correct and define as fully as possible the 

 distribution of the species in this country.
