Tegmina of female hidden under pronotum, of male barely 
exposed. Hind legs extremely long, two and one-half times as 
long as pronotum, thighs stout at base. Last dorsal segment of 
abdomen of male shallowly V-emarginate. Cerci long, straight, 
acutely pointed, bearing a short, claw-like spur or tooth on the 
upper inner side. Subgenital plate of female very deeply divided, 
the two lobes prolonged, sublanceolate. Ovipositor equal to

This appears to be the more common of our species. It matures 
late ; the young may be found in late June and July, and mature 
individuals from late July till October. It is definitely known 
from several points in the vicinity of Boston (Blue Hills, Dedham, 
Sharon, Turtle Pond Reservation) and from West Chop, Mar- 
tha's Vineyard. It probably occurs in much of the coastwise 
part of New England from southeastern Maine to Connecticut 
and extends extralimitally to Alabama and Mississippi.

Similar in color and general appearance to A. americanus but 
smaller and differing particularly as follows: lateral carina of 
pronotum straighter; tegmina of female two-thirds as long as 
pronotum; hind femora only twice as long as pronotum; pro-
