This species and the preceding can be confounded with none of 
the others from the unarmed blades of the ovipositor. The males are 
unknown.

This species is dimorphic: long-winged, with tegmina reaching 
commonly to the end of the abdomen {fasciatus); and apterous, with 
short tegmina {vittatus). To the former belongs A. hospes Fabr., and 
to the latter A. servilis Say and N. exiguus Scudd., this last not being 
Acheta exigua Say, which is an Anaxipha. 
Both forms occur throughout the range of the insect, which is from 
Nova Scotia to North Carolina in the east, westward to the plains. I 
have seen specimens from as far north as northern New England, Mon¬ 
treal, Michigan, Minnesota and Manitoba, and as far west as South Da¬ 
kota, Big Horn Mts. and Pine Cliffs, Wyo.; South Bend, West Point, 
Sydney and Lincoln, Neb.; Topeka, Shawnee and Barbour Cos., Kans. 
(all these western localities in Bruner’s collection), as well as the Platte 
River, Nebr., and Iowa; and as far south as Decatur, Ala. (L. Bruner), 
and Virginia. It has been reported from other southern localities, 
which are probably correct, as Kentucky (Garman) and Mississippi 
* (Ashmead); but of others I have some doubt, such as South Carolina, 
Louisiana and Texas (Scudder), East Florida (Walker) and Peru! 
(Bolivar), where probably other species are in question. In New Eng¬ 
land Mr. A. P. Morse has taken it on the top of Graylock, Mass.,
