The four following species form a natural group, with 
the third leg in the male modified, with the third femur en- 
larged, and one or two stout, cone-shaped spines on the 
posterior ventral side of the tibia. In both sexes there is 
a distinct dark ring near the distal end of each femur.

A widely distributed species found under dead leaves 
from New England to Texas. The position of the ventral 
furrow varies from mid-w.ay between the spinnerets and 
the epigastric plate and nearer to the epigastric plate. 
The under side of the tibia of the third' leg has two very 
short spines on the posterior side. 
A common species from Massachusetts south to Texas.

Crosby and Bishop give a very full description of the 
male, but fail to mention the enlarged third femur and the 
two stout spines on the tibia of the third leg. The palpus 
is very similar to that of A. celer , but the tibial apophysis 
is quite distinct. The upper branch is shorter and ends in 
a sharp point, and the inner branch is a thin leaf-like plate, 
folded almost double. The large rounded protuberance on 
the basal half is larger and more conspicuous than in A. 
celer. 
Type: $ D. C. Washington.
