Massachusetts I have taken adults from September 6 to October 
16. Walden records it from Connecticut, and extraHmitally it 
extends to Indiana and North CaroUna.

Nemobius carolinus Scudder, Proc. Boston Soc. Nat. Hist., vol. 19, p. 36 
(1877).— Walden, Bull. Geol. Nat. Hist. Surv. Ct., no. 16, p. 152 (1911).— 
Hebard, Proc. Acad. Nat. Sci. Phila., p. 473 (1913). 
Size medium for Nemobius, rather broad, especially the male. 
Short-winged, the tegmina covering abdomen in male, two- 
thirds or three-fourths of it in female. Ovipositor short, up- 
curved, armed at its tip with relatively few high, distant, erect 
teeth. Disto-ventral spurs of hind tibia equal in length, a char- 
acter that at once distinguishes this species from all others inhab- 
iting New England. 
Color: hair-brown, dark above, sometimes very pale on legs 
and beneath, the tegmina and pronotum nearly black in northern 
specimens. A pale line often extends along edge of tegmina. 
The coloration is exceptionally uniform and singularly free from 
spots and stripes.

This is a common Cricket locally, next to A'', fasciatus the most 
common Nemobius in New England, sometimes occurring plenti- 
fully in colonies in suitable localities, but not as generally dis- 
tributed as the latter. It frequents the densely grassed areas in 
damp pastures, and is often common under dead leaves on the 
edges of swampy woodlands, and under logs and boards near by. 
Its song is a continuous, high-pitched trill, of less volume but with 
a silvery, singing quality more pleasing to the ear than that of 
N. fasciatus. 
It is found throughout New England . I have seen it from Jack- 
man in the western part of Maine (Me. Exp. Sta.) and have taken 
it at Fort Fairfield and Caribou in the northern part of the State
